Abstract:

Abstract: The use of fast and precise procedures for seed analysis is an important factor for making decisions at different stages of seed production. The aim of this study was to evaluate the occurrence of internal damage and associate morphological traits of pearl millet seeds with their physiological potential, and evaluate seed vigor using the Seed Vigor Imaging System (SVIS®) compared to other traditional vigor tests. Eight seed lots of the pearl millet cultivar ADR 300 were analyzed for germination, vigor (first count, accelerated aging, cold test, and SVIS®), internal morphology (X-ray), and morphological parameters (perimeter, area, and roundness). The X-ray test is effective in evaluating the internal morphology of pearl millet seeds, allowing identification of mechanical damage and of deteriorated and malformed tissues, making it possible to establish a relationship between the damage observed and the negative effect on germination. SVIS® analyses on two-day-old seedlings are a reliable method for assessing seed vigor of pearl millet. Parameters of perimeter and area of the seeds are related to their physiological potential.

Abstract:

In sub-Saharan Africa, the use of maize (Zea mays L.) grain as an energy source in poultry feeds has become unsustainable due to competing demands and suboptimal growing conditions for the maize crop. Sorghum (Sorghum bicolor Moench L.) and pearl millet (Pennisetum glaucum) grains are potential sustainable alternatives, given their tolerance to local growing conditions. Therefore, this study evaluated the effect of total replacement of maize grain with whole or crushed sorghum and pearl millet grains on feed intake, and physiological and meat quality parameters of Jumbo quail. Five experimental diets were formulated by completely replacing crushed maize grain in a commercial grower diet (CON) with whole sorghum (WSG), crushed sorghum (CSG), whole millet (WMG), or crushed millet (CMG). Three hundred and fifty, two-week-old Jumbo quail chicks (74.7 ± 8.81 g live-weight) were evenly distributed into 35 replicate pens to which the experimental diets were allotted. Statistically similar (P > 0.05) weight gain and FCE values were observed between birds reared on the control and pearl millet-based diets. However, birds fed with sorghum-based diets had the lowest FCE and weight gain. Blood parameters fell within the normal ranges reported for healthy quail. Birds fed the whole sorghum grain diet had the least (P < 0.05) serum calcium and higher monocytes, cholesterol, and alkaline phosphatase (ALP) concentrations compared to those reared on the control diet. Compared to the control, the whole sorghum-containing diet reduced (P < 0.05) carcass, breast, wing, thigh, drumstick, liver, gizzard, and large intestine weights of the birds. Complete replacement of maize grain with pearl millet grain (whole or crushed) did not compromise feed intake, growth performance, and meat quality traits of the Jumbo quail birds. However, whole sorghum grain reduced growth performance of the birds.

Abstract:

AbstractWhole-grain cereal breakfast consumption has been associated with beneficial effects on glucose and insulin metabolism as well as satiety. Pearl millet is a popular ancient grain variety that can be grown in hot, dry regions. However, little is known about its health effects. The present study investigated the effect of a pearl millet porridge (PMP) compared with a well-known Scottish oats porridge (SOP) on glycaemic, gastrointestinal, hormonal and appetitive responses. In a randomised, two-way crossover trial, twenty-six healthy participants consumed two isoenergetic/isovolumetric PMP or SOP breakfast meals, served with a drink of water. Blood samples for glucose, insulin, glucagon-like peptide 1, glucose-dependent insulinotropic polypeptide (GIP), peptide YY, gastric volumes and appetite ratings were collected 2 h postprandially, followed by an ad libitum meal and food intake records for the remainder of the day. The incremental AUC (iAUC2h) for blood glucose was not significantly different between the porridges (P > 0·05). The iAUC2h for gastric volume was larger for PMP compared with SOP (P = 0·045). The iAUC2h for GIP concentration was significantly lower for PMP compared with SOP (P = 0·001). Other hormones and appetite responses were similar between meals. In conclusion, the present study reports, for the first time, data on glycaemic and physiological responses to a pearl millet breakfast, showing that this ancient grain could represent a sustainable alternative with health-promoting characteristics comparable with oats. GIP is an incretin hormone linked to TAG absorption in adipose tissue; therefore, the lower GIP response for PMP may be an added health benefit.

Abstract:

<p> </p><p>Pearl millet is a dual-purpose crop in semi-arid zones of Uganda. However, no studies have been conducted to determine the gene effects for yield and yield-related traits and rust resistance in these environments; yet this knowledge is important in improving grain yield and rust resistance. A North Carolina II mating design was adopted to study the genetic effects for rust resistance and yield-related traits of improved pearl millet genotypes. The experimental design to study the objectives was alpha in two [locations, seasons and replications]. A higher proportion of general combining ability (GCA) effect was observed for grain yield, days to 50% flowering, days to 50% anthesis, flower-anthesis interval, days to 50% physiological maturity, plant height, total tiller number, number of productive tillers, percentage of productive tillers, panicle area, leaf area, 1000-grain weight, biological yield and harvest index. The specific combining ability (SCA) effect was predominant for area under disease progress curve. Eleven hybrids performed better than the best male parent and five crosses performed better than the best female parent for grain yield while all the fifteen selected best crosses performed better than all parents for area under disease progress curve. Ten crosses were more resistant to rust than the best male parent and all the crosses were more resistant to rust than the female parents. The additive gene action was predominant for grain yield, rust severity at 50% physiological maturity, days to 50% flowering, days to 50% anthesis, total tiller number, percentage of productive tillers, panicle area, 1000-grain weight, biological yield, harvest index and leaf area. High better-parent heterosis was also observed for most traits including grain yield and rust resistance. The traits were also characterized by relatively low levels of narrow sense heritability.</p>

Abstract:

SUMMARYThe interaction of water stress and time from sowing to floral initiation was investigated in the field with pearl millet hybrid BJ 104. Extended daylength was used to delay panicle initiation (PI) and flowering (FL) of crops exposed to single periods of mid-season drought. Growth, yield and yield components were related to the number of days for PI and FL in both irrigated and water-stressed treatments. Delay in PI resulted in more leaves and tillers per plant, and greater leaf area, height and total dry matter. Grain yield, however, was not affected resulting in lower ‘harvest index’. There was, however, an increase in the grain yield of main shoots which was offset by a proportional decrease in the grain yield of tillers.Water stress effects were dependent on the physiological stage of the crop at which stress occurred, as a result of the photoperiod treatments. Water stress prior to panicle initiation did not affect the grain yield of the main shoot but increased tiller grain yield, resulting in a higher total (crop) grain yield. Water stress during panicle development reduced the grain yield on the main shoot but this loss was compensated by the grain from the increased number of tiller panicles which reached flowering. Water stress during flowering and grain filling reduced grain yields of both main shoot and tillers, making this the most sensitive stage. Photoperiodic control of floral initiation can provide an escape mechanism to avoid the coincidence of mid-season water stress with sensitive periods of growth.

Abstract:

Introduction: Pearl millet (Pennisetum glaucum) is an important cereal of traditional farming systems that has the natural ability to withstandvarious abiotic stresses such as drought, which is one of the most important manifestations of abiotic stress in plants. These plants havehowever evolved mechanisms that allow them to adapt and survive prolonged periods of water deficit at some level or form of plant structure,if not at the whole plant level. The hostile conditions augment the formation of reactive oxygen species (ROS) during physiological stresses inplants which are combated by various enzymatic and non-enzymatic mechanisms. The present study aims at examining the role of fourimportant enzymes namely Ascorbic peroxidase (APX), Peroxidase (POX), Catalase (CAT) and Superoxide Dismutase(SOD) expressed duringdrought stress in pearl millet (Pennisetum glaucum). Method: 12 and 22 days old seedlings of Pennisetum cultivar HHB-68 were subjectedto drought stress by treatment of 30% Polyethylene glycol for different time periods 30min (T1), 2hr (T2), 4hr (T3), 8hr (T4), 16hr (T5), 24hr(T6) and 48hr (T7) respectively, monitored by examining RWC of seedlings. The treatment seedlings were then used for investigating thelevels of enzymes activity in response to prolonged dehydration periods of 22 days. The enzyme activity of POX, APX, CAT and SOD wereassayed. Result: Enzymes expression was assayed for each treatment sets at both time intervals. Drought stress was observed to causeremarkable increase in POX, APX and SOD activity while incidence of CAT enzyme decreased with the increasing period of water deficit.Conclusion: Prolonged periods of water deficiency causes significant variations in expression of various enzymes in Pennisetum glaucum,known to be involved in ROS scavenging and drought stress management. The study provides a sturdy validation of the role of these enzymesas potent mechanisms undertaken by drought resistant plants for successful management of drought stress, which can be used for thedevelopment of more efficient and economic drought resistant cultivars.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.12278 Int J Appl Sci Biotechnol, Vol. 3(1): 134-138

Abstract:

Pearl millet is grown by inhabitants of the semi-arid zones. Due to the unpredictable climatic conditions the genotype-by-environment interaction (GEI) makes it hard to select genotypes adapted to such conditions. The study objectives therefore were to analyse the patterns of GEI and to identify superior genotypes for grain yield and rust resistance. Seventy six genotypes were planted in four environments in 4×19 alpha design with two replications. The ANOVA results showed that main effects of environments were significant (p ≤ 0.05) for grain yield and highly significant (p ≤ 0.001) for rust resistance while the main effects of the genotypes and their interactions with environments were also important for grain yield and rust severity at 50% physiological maturity. The GGE biplot analysis revealed that environments associated with more rains received during vegetative phase performed better than those receiving more rains during post-anthesis phase. The winner in the best environment for grain yield was ICMV3771×SDMV96053 while Shibe×CIVT9206 and Shibe×GGB8735 were the best for rust resistance.

Abstract:

: A rapid and continuous growth of silver nanoparticles (AgNPs) via their precursor “silver nitrate” (AgNO3) has increased their environmental risk because of their unsafe discharge into the surrounding environment. Both have damaging effects on plants and induce oxidative stress. In the present study, differential responses in the morpho-physiological and biochemical profiles of P. glaucum (L.) seedlings exposed to various doses of AgNPs and AgNO3 were studied. Both have forms of Ag accelerated the reactive oxygen species (ROS) production, which adversely affected the membrane stability as a result of their enhanced accumulation, and resulted in a significant reduction in growth, that is, root length, shoot length, fresh and dry biomass, and relative water content. AgNO3 possessed a higher degree of toxicity owing to its higher accumulation than AgNPs, and induced changes in the antioxidants’ enzyme activity: superoxide dismutase (SOD), peroxidase (POD), catalases (CAT), guaiacol peroxidase (GPX), ascorbate peroxidase (APX), and glutathione reductase (GR) activity, as well as proline content, total phenolic, and total flavonoids contents (TFCs) under all tested treatments (mM). A decline in photosynthetic pigments such as total chlorophyll content and carotenoid content and alterations in quantum yield (Fv/Fm), photochemical (qP), and non-photochemical quenching (NPQ) indicated the blockage of the electron transport chain (ETC), which led to a significant inhibition of photosynthesis. Interestingly, seedlings exposed to AgNPs showed less damaging effects on P. glaucum (L.) seedlings, resulting in relatively lower oxidative stress in contrast to AgNO3. Our results revealed that AgNO3 and AgNPs possessed differential phytotoxic effects on P. glaucum (L.) seedlings, including their mechanism of uptake, translocation, and action. The present findings may be useful in phytotoxic research to design strategies that minimize the adverse effects of AgNPs and AgNO3 on crops, especially in the agriculture sector.

Abstract:

Pearl millet (Pennisetum glaucum (L.) R.Br.) is a resilient crop suiting the harshest conditions of the semi-arid tropics, in which we assessed possible relationships between crop tolerance, anti-oxidative enzyme activity and plant/soil water status. Biochemical acclimation and cell homeostasis traits have been proposed as critical for the drought tolerance of crops, but their limited practical application in breeding so far suggests that the role of biochemical acclimation for drought tolerance is still unclear. Previous research may have been of limited value because it has not approached biochemical acclimation from the angle of plant water relations. Four pearl millet genotypes, contrasting for terminal drought tolerance, were evaluated (sensitive H77/833–2, tolerant PRLT2/89–33 and two near isogenic lines carrying a terminal drought tolerance quantitative trait locus) under water-stress (WS) and well-watered (WW) conditions in a lysimetric system that simulates field-like conditions. We assessed the genotypic variation and relationship between photosynthetic pigments (chlorophylls a and b and carotenoids), antioxidative isoenzymatic spectrum (superoxide dismutase, ascorbate peroxidase and catalase), physiological traits (soil moisture available, normalised transpiration, stay-green score and water extraction) and biomass and yield. Biochemical traits investigated were tightly related among each other under WS conditions but not under WW conditions. Two major ascorbate peroxidase isoforms (APX6&7), whose variation in both water regimes reflected the presence/absence of the drought tolerance quantitative trait locus, were identified, but these did not relate to yield. Both, yield and biochemical traits under terminal drought stress were closely related to the traits linked to plant/soil water status (soil moisture available, normalised transpiration, stay-green score and water extraction), whereas yield and the biochemical indicators were not correlated, except for one. It is concluded that there is no direct effect of biochemical traits on yield parameters since both are consequences of soil-plant water status and their putative relation appear to be secondary – through plant/soil water status.

Abstract:

The pearl millet seed is small and its size varies, making sowing more difficult. The pelleting technique increases and homogenizes seed size, but it is essential to determine the physical and physiological characteristics of pelleted seeds. The physiological analysis consisted of: first germination count, final germination, speed emergence index, and seedling emergence. Physical analysis consisted of determining the 1000-seed weight, 1000-seed volume and fragmentation. The control treatment did not receive any coating, and the other 36 treatments combined four binders: bentonite, polyvinyl acetate (PVA), polyvinylpyrrolidone (PVP) and methyl cellulose (Methocel®), and nine powder coating products: microcellulose, plaster, vermiculite, magnesium thermophosphate (Yoorin®), phytic acid, dicalcium phosphate, super simple phosphate (SS), monoamonic phosphate (MAP) and reactive phosphate. Among the materials used to form the pearl millet pellet, the most efficient binders were the polyvinyl acetate and the methyl cellulose, and as coaters, the vermiculite and the microcellulose.

Abstract:

In the present study effect of processing treatments viz. blanching and germination on the proximate composition of Pennisetum glaucum (pearl millet) was studied. Proximate composition was analysed by the standard methods determined according to Association of Official Analytical Chemists. Results indicated that moisture content increased significantly after processing treatments. Blanching resulted in non significant increase in ash content of pearl millet grains. The crude protein content of unprocessed pearl millet was 11.55%. The crude protein content of blanched pearl millet grains was 11.27%. Crude protein content of germinated grains was found to be 12.38% as in comparison to 11.55% in unprocessed and 11.27 in blanching treatment. Crude fat content of unprocessed (control), blanched and germinated pearl millet grains were 5.36, 5.09 and 4.55%, respectively. Fiber content increased significantly after blanching and germination processing treatments. Processing treatments not only effect the nutritional composition of pearl millet but also contribute towards enhancement of shelf life.

College of Agriculture, Navsari Agricultural University, Navsari during summer, 2019 and 2020 comprising four intercropping treatments i.e. pearlmillet sole, pearlmillet+greengram, pearlmillet+cowpea, pearlmillet+clusterbean and three fertility levels viz., 75 % RDF, 100 % RDF and 125 % RDF. Among the different intercropping system examined, sole pearl millet (I1) accumulated significantly less content of N and P in pearl millet grain and straw as compared to intercropping with pulses treatments. Pearl millet + green gram (I2) recorded significantly higher N and P uptake by pearl millet straw than other intercropping systems. The sole pearl millet (I1) was at par with pearl millet intercropped with green gram (I2) had significantly higher K content and uptake in pearl millet grain and straw. In case of fertility levels, nitrogen and phosphorus content and uptake in pearl millet grain and straw were recorded significantly higher by application of 100 % RDF. Significantly higher N, P and K uptake by pearl millet grain and straw in pooled results were produced by treatment combination of pearl millet + green gram (I2) intercropping along with 75 % RDF (F1).

Planting of pearl millet in paired rows of 30 and 70 cm gave as much yield as normal planting in uniform rows of 50 cm. The productivity per unit area was increased considerably when pearl millet was interplanted with one row of cow pea or green gram. Cow pea gave higher yield than green gram. Nitrogen fertilizer increased pearl millet as well as intercrops yield significantly. Pearl millet responded up to 60 kg N/ha and intercrops up to 30 kg N/ha. Phosphorus fertilizer did not produce marked improvement in either growth or yield of pearl millet. Application of 40 kg P2O5/ha increased grain yield of intercrops significantly

Abstract A field study was conducted in Quebec to determine the effect of crop rotation with grain pearl millet (Pennisetum glaucum) on Pratylenchus penetrans populations and the subsequent yields of two potato cultivars (Solanum tuberosum) when compared with rye and continuous potato with and without fumigation. Pearl millet had a suppressive effect on P. penetrans populations compared with rye but not as much as continuous potato with fumigation. In 2002, total potato yields of cv. Superior and cv. Hilite Russet were negatively correlated with P. penetrans densities at harvest. Total yields of potato cv. Superior were increased by 123 and 229% following pearl millet and fumigation, respectively, compared with rye. Total yields of potato cv. Hilite Russet increased by 26 and 17% following pearl millet and fumigation. Grain pearl millet CGPM H-1 reduced P. penetrans densities and improved potato yields in Quebec.

Abstract:

The use of high quality seeds is of utmost importance and is intimately related to seed vigor. The objective of this study was to stablish a novel methodology for evaluating the vigor of pearl millet seeds. The experiment was performed at the Federal University of Pelotas, using 5 seed lots of pearl millet cv. BRS1501. The research was carried out in two stages: first, seed lots were characterized (physiological quality tests); second, the initial emergence and development of pearl millet seedlings was evaluated, testing four different substrates and five sowing depths in the emergence test. The experimental set up consisted of a completely randomized design with four replicates. Means were compared by the Scott-Knott test at the 5% probability level. The substrates sand and carbonized rice husk, at 1.0 cm depth, satisfactorily stratified seed lots. These methodologies correlated with the speed of emergency index and seedling emergency. Thus, the study identified an innovative method for testing vigor in pearl millet seeds.

Abstract:

SummaryA 2-year field study indicated that pearl millet yielded more when sown after fallow, cow pea and green gram than after maize. Preceding fallow, cow pea and green gram reduced the nitrogen requirement of pearl millet by 40 kg/ha compared with maize. Pearl millet responded linearly up to the highest rate of nitrogen (80 kg/ha). N applied to millet had no residual effect on the subsequent crop of chickpea. The chickpea yield followed the order fallow > green gram ≥ cow pea > maize. Chickpea responded to phosphorus up to 40 kg/ha. Green gram-pearl millet-chickpea proved the most profitable cropping sequence. Continuous cropping and application of nitrogen and phosphorus improved the organic carbon and available phosphorus but decreased the available potassium status of the soil.

Abstract:

Background: Millets are small-seeded cereals having excellent nutritional quality. They are comparable or superior to some commonly consumed cereals like wheat and rice. Millets are gluten-free, have low Glycemic Index and are a good source of calcium, iron, potassium, zinc magnesium and B vitamins. Natural fermentation of millets can improve their lower cooking quality, taste, low bioavailability and palatability. Objective: This study was undertaken to evaluate the effect of natural fermentation on antioxidant activity of Pearl millet (Pennisetum glaucum). Methods: The present work has been done to standardize the natural fermentation process of pearl millet using response surface methodology for enhanced iron content and antioxidant activity. Pearl millet was treated with natural fermentation process at varying temperature (30-50°C), time (4-12 hrs) and pH (3-7). The effect of these fermentation treatments were studied on total reducing sugar, iron content, antioxidant activity (Total Phenolic content and DPPH), tannin content and antinutritional factors of pearl millet using a second order central composite design. Results: The cofficient of determination, R2 values for Total reducing sugar, iron content, antioxidant activity and tannin content was greater than 0.900. Statistical analysis showed that sugar, iron content, antioxidant activity and tannin content varied significantly (p <0.05) with a change in pH, temperature and time. pH was found to be the most important factor affecting the quality parameters of the pearl millet during fermentation as it exerted a strong influence (p < 0.01) on all the dependent variables. Conclusion: Increase in total reducing sugar, iron content, antioxidant activity and decrease in tannin content of pearl millet were observed along with a decrease in pH and temperature of fermentation. On the basis of response surface and contour plots, the fermentation conditions of pearl millet were optimized at a temperature of 40°C, pH 5 and time duration of 8 hours.

Abstract:

Production of pearl millet with yield improvement would have a direct impact on the drought-prone areas of Ethiopia since pearl millet is drought tolerant and early maturing with high water use efficiency. An experiment was conducted to study the performance of pearl millet under different technologies in 2013 and 2014 main cropping seasons at the main site of the research center, Aybra, with the objective of evaluating and identifying appropriate combinations of technologies that enhance the production of pearl millet in the study area. About fourteen integrated technologies were applied in a randomized complete block design with three replications. The analysis was done by using SAS software version 9.1, and means were separated through the Duncan multiple range test. Results of analysis of variance showed that yield-related traits of pearl millet were significantly influenced by the integration of technologies in the 2013 cropping season. According to the results, the maximum yield (3084 kg ha−1) was recorded with the application of the treatment combination of recommended fertilizer application + seed primming + tie ridging, while the minimum was recorded (919 kg ha−1) in the treatment combination of microdose application of fertilizer + primed seed + intercropping of pearl millet with mung bean. In the case of the 2014 cropping season, the highest grain yield (3687 kg ha−1) was recorded with the treatment combination of microdose fertilizer application + primed seed + tie ridging + intercropping of pearl millet with mung bean, whereas the lowest grain yield (2115 kg ha−1) was recorded in the treatment combination of no fertilizer application + primed seed + flat bed. Based on the results of the current investigation, it could be recommended that using technology integration of microdose, tied ridge, primed seed, and intercropping of pearl millet with mung bean is better to attain maximum yield in the study area and similar agroecologies.

Abstract:

ABSTRACT The present study aimed to investigate the temperature at different depths of the stack silo and strata front profile before and after the removal of silage. Also, the pH values in the upper and lower profile and the silage density of the fresh materials (FM) and dry matter (DM) in pearl millet silages with particle sizes of 5 or 20 mm, with or without inoculant, were assessed, using corn silage as controls. There was an interaction (P<0.05) silage × stratum profile and silage × depth profile for the temperatures before the removal of silage, and the pearl millet silages had lower temperatures in the upper stratum compared to corn. The temperature gradient between the silage and environment pearl millet and corn silos were smaller in the lower stratum profile. The temperature gradient after the removal of the silage was less than 50 cm deep at all the pearl millet silos. There were no differences in the densities of the FM and DM of the studied silages. The pH values of the silages before their removal were higher in the upper stratum and lower stratum in the bottom of all the pearl millet silages, in contrast with corn silage. The pearl millet silos had lower pH values in the lower stratum of the silo. Silages with 5 mm particle size provide lower temperatures in the middle portion of the panel before the removal of the silage. The use of bacterial inoculant in this study did not change the characteristics evaluated.

Abstract:

AbstractWhile crop rotations improve soil quality indicators and crop yields in humid temperate regions, much less information is available under harsher arid tropical and subtropical conditions. A field experiment conducted from 1990 to 1993 compared the effect of continuous pearl millet and pearl millet-fallow systems with six rotations of pearl millet that included one, two, or three years of a legume (cluster bean or mung bean). Data were collected on several soil quality indicators and pearl millet yield. Continuous pearl millet monoculture for three y ears did not affect soil organic C, NaHCO3-soluble P, DTPA extractable Fe, Cu, Mn, or Zn, or several soil organic N fractions, but slightly increased activity of dehydrogenase and acid and alkaline phosphatase enzymes. Similar trends were observed for fallow-based cropping systems, except that enzyme activities were lower. Cropping systems containing mung bean or cluster bean improved availability of soil N and other nutrients and increased enzyme activity. These effects increased with number of years of legume. Improvements from cluster bean generally were greater than from mung bean. The lowest pearl milkt yield was obtained with continuous pearl millet and no N, and yields f or fallow-based cropping systems were 13% greater than with continuous pearl millet. Grain yields of pearl millet with two or three years of mung bean in the cropping system were, respectively, 37 and 65% greater than for continuous pearl millet; with cluster bean the corresponding increases were 68 and 101%. Pearl millet yield increased with N applications up to 40 kg/ha under all cropping systems, and up to 60 kg/ha for some cluster bean-based systems. Yield of pearl millet following cluster bean was nearly double that of continuous pearl millet. These results indicate that in hot, dry climates cropping systems that include a legume, especially cluster bean, are more productive, use the limited water supply and fertilizer N more effectively, and improve several soil quality indicators more than do cropping systems without legumes.

SummaryIn a field experiment conducted from 1981 to 1984 on alluvial soil (Ustochrept) of Jalandhar, green manure (GM) of dhaincha, sannhemp, pearl millet and moong did not affect tuber yield in the 1st year but increased it in the 2nd and 3rd years. GM of dhaincha and sannhemp were more effective than the moong in reducing responses of potatoes to K. GM of pearl millet was as effective as the dhaincha or sannhemp in 1981–2 and 1982–3 when buried 55 days after sowing but was inferior in 1983–4 when buried 85 days after sowing and resulted in reduced concentrations of N and P in potato plants. GM of dhaincha, sannhemp and pearl millet increased concentration of K in potato plants and available K in soil. GM of dhaincha and sannhemp, in particular, increased soil available K by decreasing non-exchangeable K whereas GM of pearl millet increased soil available K without affecting non-exchangeable K.

Abstract:

Pearl millet (Pennisitum glaucum L.) is a warm season C4 grass well adapted to semiarid climates where concerns over scarce and depleting water resources continually prompt the search for water efficient crop management to improve water use efficiency (WUE). A two-year study was conducted in the Southern Great Plains, USA, semi-arid region, to determine optimum levels of irrigation, row spacing, and tillage to maximize WUE and maintain forage production in pearl millet. Pearl millet was planted in a strip-split-plot factorial design at two row widths, 76 and 19 cm, in tilled and no-till soil under three irrigation levels (high, moderate, and limited). The results were consistent between production years. Both WUE and forage yield were impacted by tillage; however, irrigation level had the greatest effect on forage production. Row spacing had no effect on either WUE or forage yield. The pearl millet water use-yield production function was y = 6.68 × x (mm) − 837 kg ha−1; however, a low coefficient of determination (r2 = 0.31) suggests that factors other than water use (WU), such as a low leaf area index (LAI), had greater influence on dry matter (DM) production. Highest WUE (6.13 Mg ha−1 mm−1) was achieved in tilled soil due to greater LAI and DM production than in no-till.

Abstract:

Abstract Pearl millet (Pennisetum glaucum) is considered an important kharif crop, which is grown extensively in the arid and semi-arid tropical regions, where other crops, like sorghum and maize, fail to produce economic yields. Its grains are valued as human food, while its dry stover makes significant livestock ration in croplivestock farming system. Pearl millets (MB-87), a newly developed variety of Fodder Research Institute, Sargodha, Pakistan, is one of the best pearl millet variety, which gives more than one cutting and helps to cope with fodder lean period, as well as more income can be generated in addition to seed. So, overcome the scarcity period the study was conducted to check the effect of last cutting dates on seed production of multicut pearl millet MB-87 was conducted at Fodder Research Institute, Sargodha, Pakistan, during 2015 and 2016. Following parameters were taken in to consideration, i.e. plant height (cm), stem thickness (cm), number of leaves per tiller, number of tillers per plant, green fodder yield (t/ha), length of head (cm), 1000 grains weight (g) and grain yield (kg/ha). The results depicted that grain yield, i.e. 319.20, was maximum and head length was highest, i.e. 35.13 cm on 20th of August having last date of cut, whereas all others parameters were found to be nonsignificant. Multicut bajra gives three cutting of fodder, followed by seed, as compared with conventional bajra, which gives only one cutting or seed. Therefore, it is more economical for the growers of fodders to grow the pearl millets MB-87 as fodder, as well as for seed purposes. So, it is concluded that for gaining maximum grain yield of multicut pearl millet MB-87 the last cutting date should be 20th of August. In future, pearl millet is likely to play a larger role in providing food and nutritional security.

Abstract:

A field experiment was conducted at Panwari village of Agra district during Kharif and rabi season of 2015-16 and 2016-17 to study the effect of sulphur and zinc management on yield, nutrient uptake and residual soil fertility under pearl millet (Pennisetum glaucum) – lentil (Lens culinaris Medikus) crop sequence. Four levels each of sulphur and zinc were evaluated under randomized block design with three replications. Both the nutrients were applied to pearl millet and their direct and residual response was ascertained to pearl millet and lentil in sequence. Pooled results indicated that grain and stover yield of pearl millet improved significantly with increasing levels of S up to 20 kg S ha-1 over control. An increase of 17.0 and 16.5 % in grain and stover yield was recorded with 20 kg S ha-1 over control. Similarly, grain and stover yield of pearl millet increased significantly with Zn and maximum grain (3.46 t ha-1 ) and stover (8.19 t ha-1 ) yields were recorded with 4 kg Zn ha-1 . The content and yield of protein in both the crops increased significantly with the addition of S and Zn over control. The residual effect of S in lentil was significant at 40 kg S ha-1 and grain and straw yield increments were to the extent of 18.6 and 15.8 per cent, respectively. The residual effect of 6 kg Zn ha-1 on succeeding lentil crop produced 16.7 and 14.0 % higher grain and straw yield over control, respectively. Application of S and Zn showed significantly beneficial effect on S and Zn uptake by pearl millet and succeeding lentil crop over control. Nitrogen and P uptake by both the crops also improved significantly with these elements over control

A Field experiment was conducted at Crop Research Farm, Chaudhary Charan Singh Haryana Agricultural University, Hisar, during the kharif seasons of 2004 and 2005 to find out suitable spacing for pearl millet hybrids along with N and P levels so as to increase the productivity of pearl millet. The experiment was laid out in split plot design allocating combinations of two hybrids and three plant densities in main plots and four fertility levels in sub plots with three replications. Highest pooled grain yield was recorded by HHB 67-2. Sowing pearl millet at 45x12 cm spacing produced highest pooled grain and stover yield. Application of 90 kg N + 45 kg P2O5 ha–1 resulted maximum pooled grain and stover yield and was at par with 60 kg N + 30 kg P2O5 ha–1. HHB 67-2 had significantly higher total uptake over HHB 67. Wider spacing of 60x12 cm had higher NPK content but 45x12 cm resulted into higher total uptake of NPK. NPK content and uptake was found higher when pearl millet was fertilized with 90 kg N + 45 kg P2O5 ha–1.

Abstract:

Pearl millet crop has been increasingly growing in Brazilian Savanna and it is already being used as cover crop between annual crops. The plant has great forage potential, besides being a nutrient recycling plant due to its peculiar root system. This study was developed in order to assess the pearl millet nutritional value when submitted to nitrogen fertilizer. It was evaluated the effect of nitrogen fertilizer (ammonium sulfate nitrate) treated with the nitrification inhibitor 3,4-dimethyl pyrazole phosphate (DMPP) on the ruminal degradability of two pearl millets’ cultivars, under four nitrogen fertilization levels (0, 45, 90 and 180 kg ha-1) and pre-cutting heights (0.70, 0.80 and 0.90 m). The experimental design was a randomized block design in a factorial 3 × 4 (3 cutting heights × 4 nitrogen doses) with three replications. Data were submitted to analysis of variance and means were compared by Tukey test at 5% probability. The DMPP treated Nitrogen, in high doses, increased the dry matter, crude protein and neutral detergent insoluble fiber degradability in pearl millet handled at 0.90 m. The combination of fertilization with 45 or 90 kg ha-1 of nitrogen treated with DMPP, with the management of millet at 0.70 or 0.80 m did not favored the forage nutritional quality, indicating that in these treatments, the ratio between the availability of nitrogen in ammonium and nitrate forms may have been detrimental to the plants.

Abstract:

The present investigation was conducted to study the effect of storage period on flour quality of wheat, maize and pearl millet. Their flour were stored at 15 °C and 82 % relative humidity RH for one month and changes in fat acidity (FA), activities of peroxidase (POX), lipoxygenase (LOX) and polyphenol oxidase (PPO) in control and stored flour along with change in pH of water extract of flour were monitored. Increase in FA (mg KOH/100 g d.m.) and decrease in pH of flour was maximal in pearl millet (287.5 mg KOH/100 g d.m. and 0.4) followed by maize (151 mg KOH/100 g d.m. and 0.23) and wheat (61 mg KOH/100 g d.m. and 0.1) respectively. A decline in activity of POX, LOX and PPO was observed during storage. Pearl millet flour possessed almost double activity of POX (413 Units/g d.m.) in comparison to wheat (198 Units/g d.m.) and 1.3 fold higher than that of maize (153 Units/g d.m.) and even after decrease activity of POX was higher in flour of pearl millet compared to the other two. However, activity of LOX and PPO was found to be comparable in fresh flour of pearl millet, maize and wheat. Since pearl millet has poor shelf life and increase in FA, decrease in pH and activity of POX was found to be very high in pearl millet (poor shelf life) as compared to wheat and maize, therefore, these selected parameters might be used as biochemical markers to determine shelf life of flour.

Full text

Abstract:

Abscission of the stigmas of pearl millet (Pennisetum typhoides (Burman) Stapf et Hubbard) after pollination results from the activation of a specialized zone of tissue near the base. This abscission zone comprises a well-defined stretch of the basal column made up of thin-walled cells lacking a cuticularized epidermis. The penetration of the first few pollen tubes following a compatible pollination results in loss of turgor throughout the tissue, followed by loss of adhesion between the cells and ultimately disruption of the whole zone. Pectolytic enzymes are released concomitantly, but the cellulosic skeletons of the cells persist. Numerous calcium oxalate druses, identified cytochemically and by energy-dispersive X-ray analysis, are present in the cells of the abscission zone; these undergo dissolution after activation of the zone, while simultaneously the druse population in the stigma stump and the upper ovary wall increases. The barrier formed by the degenerating abscission zone tissues excludes pollen tubes arriving after the initial activation and prevents the penetration of pathogens such as ergot and so has a prophylactic role. We suggest that the collapsed abscission zone forms not only a physical barrier but also a chemical one. Dissolution products of the numerous calcium oxalate druses during the breakdown of the tissue are likely to raise the calcium ion concentrations beyond the optimum for pollen-tube growth, thereby preventing further penetration. Inhibited tubes swell at the tips and may show growth disorientation before arrest, responses similar to those seen in pearl millet tubes in culture when exposed to higher than normal calcium ion concentration. Key words: Pennisetum typhoides, stigma abscission, millet (pearl), calcium oxalate druses, pollen-tube inhibition, abscission.

Abstract:

Intercropping of pearl millet (Pennisetum glaucum) with clusterbean (Cyamopsis tetragonoloba) is a common practice in the arid zone of northwestern India. Field experiments were conducted for two years to examine the performance of two contrasting genotypes of each of these crops grown both as sole crops and as intercrops using all possible genotypic combinations of the pearl millet with the clusterbean. The seed yields of both crops were always lower in intercropping than in sole cropping, though the degree of reduction in the seed yield of each intercrop component was influenced greatly by the genotype of its companion crop. The seed yield of both clusterbean genotypes was reduced more when intercropped with the tall and late-maturing pearl millet, MH 179, than with the medium-statured and early-maturing HHB 67. On the other hand, the two clusterbean cultivars had similar effects on intercropped pearl millet. As a result, the highest land equivalent ratios (LERs) were obtained with intercrops containing pearl millet HHB 67 rather than MH 179, while the genotype of clusterbean had little overall effect on LER. The results obtained are discussed in the context of developing cultivars for intercropping.

Abstract:

SUMMARYTopsoil depth and yields of sorghum, pearl millet and castor bean were found to be positively correlated when monitored over thirteen seasons under widely varying rainfall conditions on an Alfisol in Andhra Pradesh, India. Yields responded up to 2.5 times more to topsoil depth when rainfall in the critical period exceeded evapotranspiration than under drier conditions. Yield variations were explained by topsoil depth in cereals, and by the interaction between rainfall during the critical period and topsoil depth in cereals and castor bean (R2<0.72). The expected yield losses as a result of erosion, based on 56 years of rainfall data, were 138, 84 and 51 kg ha−1cm−1for sorghum, pearl millet and castor bean, respectively. Quadratic models explained the yield losses due to cumulative erosion under conditions of both poor and good rainfall during the critical period. Sorghum and pearl millet tended to produce no yield when erosion exceeded 34 cm and castor bean when it exceeded 40 cm. There was less reduction in yield when rainfall was poor, up to about 10 cm of erosion, than when rainfall was good. The results indicate that pearl millet and castor bean are more suitable than sorghum for low rainfall and eroded conditions.

Abstract:

Drought stress is an important limitation to the growth and grain yield of pearl millet in arid and semi-arid regions of the world. Potassium iodide, a senescing agent, was used as a screening tool for evaluating drought tolerance of 22 strains of pearl millet at the grain development stage (grain filling) under glasshouse conditions. In order to use potassium iodide as a selection method in breeding programs for improvement of drought tolerance, the technique was compared with some drought evaluating parameters such as water retention capability, osmotic adjustment, photosynthetic capacity and water-use efficiency. Application of a 0.3% solution of potassium iodide at anthesis was very effective in causing drought stress, and hence grain yield reduction, in pearl millet. It showed a significant association with water deficit in growth attributes such as fresh and dry weights of shoots, and grain yield. Osmotic adjustment, water retention capability (decrease in weight of excised leaves during 5-h drying period), photosynthetic rate, and single-leaf water-use efficiency (net CO2 assimilation rate/transpiration) did not show positive relationships with the degree of drought tolerance measured using potassium iodide spray or water-deficit treatment. A large amount of variation in drought tolerance observed in 22 lines of pearl millet can be of considerable practical value. For example, the 3 lines ICMP-83720, ICMV-9413 and ICMV-94472, ranked as highly drought tolerant on the basis of their overall growth and physiological performance, and could be of direct use under mild drought conditions.

Abstract:

Recombination between wild and cultivated genomes of pearl millet were studied by multivariate analysis on morphological and physiological traits in backcross progenies from four cultivated × wild crosses. The cultivated genotypes, Souna and Thiotandé, have evolved in sympatric and allopatric situations, respectively, with wild forms. The distinct evolutionary history of the cultivated genotypes seems to have an incidence on the segregation pattern of their progenies with the wild relatives. Segregation distortions favouring the recovery of "wild-like" phenotypes were observed in progenies with Thiotandé as the cultivated parent. They are probably a consequence of the genetic divergence between this genotype and wild forms already shown at different levels of observation (histological, physiological, and genetic). On the other hand, when Souna is the cultivated parent, the recovery of "cultivated-like" phenotypes was shown to be easier with Souna as the female. This could be due to preferential homogametic fertilization favouring "Souna-type" gametes on Souna pistils owing to intergametophytic competition through a pollen–pistil interaction, already evidenced on the genotypes used here.Key words: pearl millet, multivariate analysis, segregation distortion, wild/cultivated genome recombination, genetic resources.
