<p>The mechanism of reforms is not given enough government funding and financial assistance to the agriculture sector. This impacted the conditions of cultivation, particularly in rural living conditions. The impact of free trade brought unstable prices, difficulties in agriculture export and import and which is affected farmer’s welfare, livelihood, and other employment alternatives. The most adverse effect that has become a curse to farmers is the multiple of low price and instability in the output of cash crops. Andhra Pradesh mostly depends on rainfall agriculture. Monsoon and seasonal conditions play a crucial role in Andhra Pradesh agriculture. The proportion of area under agriculture is 37.30 percent (including fish ponds). The gross irrigated area (35.81 lakh hectares) is 48.29 percent of gross area sown (74.18 lakh hectare.) in the state. The ratio of gross irrigated area to net irrigated area is 1.32 in 2016-17, where it was 1.29 in 2015-16. (Agricultural Statistics at a Glance 2016-17). An attempt is made to study in depth the evolution of cost conditions in the rainfed and irrigated land agricultural practices, regarding the sustainability of livelihood practices. Both quantitative and qualitative methods of research were applied in the study through a collection of data by household survey and in-depth interviews, site visits, and field observations. For an understanding of costs and returns, calculate Cost A, Cost B and Cost C and Gross, Farm Business, Family Labour, Net, Farm Investment Incomes. The policymakers should focus on strict implement National Commission on farmer’s recommendations of increasing MSP should be at least 50 percent more than the weighted average cost of production, introduce availability of the leased technology (i.e. crop sowing and cutting machines etc.) to marginal and small farmers, reduce the inequalities between villages and towns and promote Zero Budget Natural Farming across the country.</p>

Full textAbstract:
The pinto bean breeding line 94-4 (Phaseolus vulgaris L.) showed seed coat yellowing in on-farm field trials in Nebraska in 1996. After reviewing weather data, sprinkler irrigation appeared to be one of the cultural factors involved with increase in seed coat yellowing. Cultural conditions were again investigated in 1997 in on-farm trials. In one test half of the NE 94-4 plants were cut and combined promptly while the other half of the cut plants were left on the ground, rained upon, and combined later. Seed from the pods of former and latter treatments were compared for degree of seed coat yellowing. Yellowing was recorded visually by determining percentage of the yellow area on a bean seed. The seed from the pods of the cut wetted plants showed more discoloration than seed from the plants that were not rained on. In another experiment two or four samples (40 g each) were taken from each of seven cultivars as well as NE 94-4 to determine degree of yellow discoloration of seed. The percent seed coat yellowing of the varieties/line was as follows: `Apache' 12.5%, `Bill Z' 14.9%, `Buckskin' 20.7%, `Chase' 9.2%, `NE-94-4' 54.1%, `179' 48%, `Vision' 35.5%, `Winchester' 10%. Results of pigment extraction and simulated irrigation experiments will be presented in order to better explain the cause of pinto seed coat yellowing.

A pot experiment was conducted under rainfed condition to study the effect of water hyacinth compost on the morpho-physiological parameters of soybean (Glycine max L.) at the Teaching and Research Farm of Faculty of Agriculture and Veterinary Medicine, Imo State University, Owerri. The treatments were control (T1) 100g (T2), 150g (T3) and 200g (T4) of water hyacinth compost and replicated four times. The treatments were arranged in Complete Randomized Design (CRD). The parameters measured were plant height, number of leaves, leaf area (cm2), leaf area index, relative growth rate (RGR), Net assimilation rate (NAR), shoot dry weight(g), yield and yield components (Number of pods, pods weight, 100 seed weight). The results obtained indicated that T3 significantly produced highest plant height (57.6cm) compare to control. While it was observed that T4 (200g) significantly produced the highest number of leaves (233.25), leaf area (631.80cm2), shoot dry weight (15.445g), number of pods (129.75), pod weights (25.38g) seed weight (7.23g) and yield (0.72kg/ha) relative to control and other treatment levels. Root parameters were also significantly improved by the rates of water hyacinth application compared to control. It will be worthy to note that there was no nodulation perhaps that was why the yield was poor. The results showed that soybean growth can effectively be improved with incorporation of water hyacinth into soil.

Full textAbstract:
Three varieties of groundnut were used to assess the drought tolerance and high yielding potential. Groundnut (Arachis hypogaea L.) is an important oil seed crop mainly grown under rainfed situation. Erratic rainfall and frequent drought during the crop growth period, groundnut yields are generally low under rainfed conditions. Drought during critical crop growth stages is crucial for loss in yield of groundnut varieties. But tolerant genotypes may give better yield due to maintenance of physiological responses that were triggered during drought. On Farm Trials was conducted by Krishi Vigyan Kendra, Hansroever campus, Perambalur district in Tamilnadu, India to assess suitable drought tolerant and high yielding groundnut variety in terms of yield, acceptability and adoption potential during rabi 2018-19 in Perambalur district, India. Three varieties of groundnut were used to assess the drought tolerance and high yielding potential viz., Dharani, Co7 and TMV 7. The study revealed that Dharani recorded higher pod yield (2402 kg ha-1), higher number of pods plant-1 (26) and optimum plant population (26.3 plants m-2) as compared to farmers practice. The groundnut variety Dharani resulted in the highest shelling percentage (75%), while the lowest was registered with TMV 7. Gross and net returns were ` 115324 and ` 66593 ha-1, respectively by cultivating Dharani as against ` 87523 and ` 41550 ha-1 in the check variety. Dharani and Co7 would be a better option forrainfed cultivation in Perambalur district.

Full textAbstract:
Peanuts are regarded as the second most important commodity after soybeans which have quite high economic value. Its production tends to decrease every year due to the reduction in planting areas. Meanwhile, the rainfed paddy fields land in Central Java is quite potential, thus its utilization can be used as an alternative to developing peanut. Accordingly, this study aims to find out the level of income and feasibility of peanut farming in Tegalsari Barat, Ampelgading Subdistrict, Pemalang District, Indonesia. The sampling was performed using purposive random sampling method with a total of 22 people. The level of profit could be found by using the return cost ratio (R/C ratio). The results indicated that during one planting season, the average cost was IDR 12,647,000 ha-1. The average production of peanut was 4,600 kg ha-1 wet pods with a selling price at farm level of IDR 8,500, so the average revenue was IDR 39,100,000 ha-1. The analysis of R/C feasibility showing the value of 3.09 (R/C > 1) indicates that peanut farming in the 3rd Planting Season (PS-3) in Pemalang District is feasible to be cultivated.

Field experiment was conducted at Instructional Farm, Jaguli (Mohanpur), Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India during two consecutive summer seasons of 2010-11, and 2011-12. The experiment was laid out in split-plot design having 4 levels of irrigation rainfed without mulch, rainfed with mulch, irrigation at IW (depth of irrigation water) / CPE (Cumulative pan evaporation) ratios of 0.5 and 0.75 in main-plot and 4 inter cropping systems, sole maize, sole mungbean, maize + mungbean (1:1 row ratio) and maize + mungbean (3:2 row ratio) considered as sub-plot treatments replicated thrice. Results revealed that application of irrigation and intercropping systems markedly influenced the growth, yield and yield components (number of cobs/plant, number of grains/cob in case of maize and number of pods/plant and number of seeds/pod in case of mungbean) where the maximum value of these components were recorded with the application of irrigation at IW/CPE ratio 0.75 in sole crop. Maize-mungbean in 3:2 row ratio yielded higher than that of 1:1 intercropping system which might be due to less light interception and more competition for water and nutrition between both the crops. CU of water increased with the increasing levels of irrigation and the maximum value (17.75 kg ha-1 mm- 1) of WUE (water use efficiency) was observed with irrigation at IW: CPE ratio 0.75 under intercropping system of maize : mungbean in 3:2 row ratio followed by IW: CPE ratio 0.50. Among the sole crop, maximum WUE was with IW/CPE ratio 0.75 might be due to more consumption of water corresponding to production potential of maize, while, it was more under rainfed with mulch in mungbean. The relative crowding coefficient (RCC) also revealed both the intercropping systems were advantageous and the land equivalent ratio (LER) increased with the level of irrigation.Thus, maize grown in association with mungbean (3:2 row ratio) were found to be more profitable (B:C ratio of 2.58) with higher monetary advantage as compared to sole crop of maize (B:C ratio of 1.98) with the application of irrigation at IW: CPE ratio of 0.75 in new alluvial zone of West Bengal.SAARC J.

Crop and Pasture Science 65, no. 7 (2014): 602. http://dx.doi.org/10.1071/cp13331.
Full textAbstract:
The time of sowing chickpea (Cicer arietinum L.) in the High Barind Tract of north-west Bangladesh is critical to crop success. To ensure adequate emergence and subsequent crop growth, chickpea relies on residual soil moisture stored in the profile after rice (Oryza sativa L.) cultivated in the preceding rainy season. With the development of mechanised, one-pass minimum tillage sowing, the time between rice harvest and chickpea sowing is decreased, and temperature constraints that limit biomass and/or pod formation and filling may be avoided. Minimum tillage may also limit evaporation from the soil surface compared with traditional, full cultivation procedures. The objective of this study was to identify the optimum sowing time to achieve adequate crop establishment and limit exposure of the chickpea crop to terminal drought and heat stress later in the growing season. Over three experimental seasons, chickpea sowing dates were spread from 22 November to 22 December. Soil water content, crop growth and temperature were monitored to determine the optimum sowing time. Over all seasons and sowing dates, the volumetric soil water content in the seedbed under minimum tillage remained within 17–34%, a range non-limiting for chickpea establishment in glasshouse and field experiments. Late planting (after 10 December) exposed seedlings to low temperatures (<15°C), which limited biomass formation and extended the vegetative growth phase into periods with high maximum temperatures (>35°C), resulting in unfilled pods and depressed grain yield. The preferred sowing time was determined to be 30 November to 10 December to reduce the risk of high temperatures and low soil water content during chickpea reproductive growth causing terminal heat and drought stress, respectively. Mechanised sowing in one operation allows farmers to optimise their time of sowing to match seed requirements for soil water at emergence and may assist farmers to avoid temperature stresses (both low and high) that constrain chickpea vegetative and reproductive growth.

Full textAbstract:
Abstract This study investigates the potential impacts of climate change on water resources and evaluates adaptation strategies on rainfed rice water management under climate change scenarios in the Songkhram River Basin, Thailand. The Soil and Water Assessment Tool (SWAT) model was used to project the future water availability under climate change scenarios for the period of 2020–2044. Future annual water availability is expected to remain unchanged due to unchanged future rainfall but expected to reduce from June to November due to changes in seasonal rainfall. The effects of supplying irrigation water to reduce the impact of climate change and increase rainfed rice production were evaluated. To increase the rice production by 15%, it is proposed to construct a reservoir with a capacity of below 65 MCM in each of the 15 sub-basins to fulfill the irrigation water requirements during the rainfed rice season. Alternatively, adaptation at the farm scale can be implemented by constructing ponds with a capacity of 900 m3 to store water for 1 ha of rice field to meet the potential rice yield during the non-rainfed rice season. The results of this study are helpful to policymakers in understanding the potential impacts of climate change and the formulation of adaptation strategies for water and rice sectors in the basin.

India has been predominantly an agricultural country. The progress of India is very much dependent on the development of agriculture. In recent years, effect of climate change seen in the form of long dry spells and heavy rains in rainfed areas causing drought and floods, respectively. However, these vagaries can be overcome by adopting soil conservation measures, changing cropping pattern, rain water harvesting etc., The present study was undertaken ‘to know the utilization pattern of the components by the KBS beneficiaries’ in Bagalkot and Vijayapura districts of Karnataka during 2017-2018 by the ex-post-facto research design with the sample size of 120 beneficiaries. The results revealed that contour bunds were constructed to increase ground water table (6.67 %) and control erosion (5.83 %). The probable reason might be that, majority of them having semi-medium land holdings. So, they are not ready to reduce the area on their productive lands. All the beneficiaries were constructed farm ponds to harvest rain water to provide protective irrigations in critical stages of crops to get good yield, collected water is also used for providing drinking water for humans and animals (77.50 %). All the beneficiaries installed diesel pump set to lift water from farm pond. Diesel pump is available in lower price and is compulsory to get subsidy under this scheme. So, the poor farmers can able to purchase and used for own purpose. Forty per cent of beneficiaries providing irrigations to the crops through sprinkler irrigations once in two weeks. So, that not even a drop is wasted and crop gets the required quantity of water at the right time for better yield. Thirty-five per cent of beneficiaries growing capsicum and tomato (15.00 %) in poly house. This study implies that KBS is facilitating the farming community not only in increasing production and productivity, but also in conserving natural resources to the greater extent. Therefore, the replication of the KBS for the non-beneficiaries is most desired to transform the socio-economic condition of the farming community at large.

The present investigation was carried out in 0.8 ha rainfed farm from April 2010 to March 2013 with two sources of water i.e. no pond/rainfed and pond/irrigated in five different blocks viz., Khajuripada of Kandhamal district (North Eastern Ghats Zone), Dhenkanal Sadar and Odapada of Dhenkanal district (Mid Central Table Land Zone), Golamunda and Narla of Kalahandi district (Western Undulating Zone) of Odisha. The 0.8 ha Integrated Farming System (IFS) model farm recorded 31.92 q Rice Equivalent Yield (REY) which was 7.4 times higher productivity than conventional rice-greengram system. The net return in IFS model was Rs. 1,61,148/- as compared to Rs. 11,631/- in conventional rice-greengram cropping system. The recyclable wastes of 3.3 t paddy straw, 3000 kg pond silt, 2129 kg poultry excreta and 13 t mushroom spent in IFS model were used as input by other units. Due to efficient recycling of wastes, the productivity and profitability of IFS models were higher compared to conventional cropping system. Thus, almost no waste was left to pollute the environment or to degrade the resource base where as the wastes in conventional system were not utilized effectively.

Maize (Zea mays L.) is one of the most versatile crop grown throughout the tropical as well as temperate regions of the world. On the other hand, the lathyrus or grass pea or chickling pea is also called ‘khesari’ and is a very hardy crop that thrives well under adverse climatic conditions. It can fix biological nitrogen in their roots through symbiotic relationship with Rhizobium leguminoseram. The field experiment was conducted on seed priming of hybrid maize and lathyrus at Central Research Farm, BCKV, Nadia under new alluvial zone of West Bengal, India in Randomized Complete Block Design (RCBD) with 3 replications during kharif season of 2016 and 2017 and rabi season of 2016-17 and 2017-18. Experimental results reveal that seed priming methods significantly influenced the germination, growth parameters, yield attributes and yield of hybrid maize-lathyrus grown in sequence under rainfed situation. Seed priming with ZnSO4 @ 0.5% for 12 hours recorded the highest number of grains per cob (319.9) and highest plant height (262.10 cm) at harvest of hybrid maize. Grain yield and stover yield of hybrid maize showed positive and highly significant (P = 0.01) with each other (r = 0.945). The maximum number of pods per plant (50.28) was observed in seed priming with ZnSO4 @ 0.5% for 12 hours and was statistically at par with seed priming with KNO3 @ 0.5% for 12 hours (48.33) in case of lathyrus. Number of pods/ plants showed positive and highly significant (P = 0.01) correlation with grain yield (r = 0.986) of lathyrus. On the basis of pooled values of 2 years of experimentation, seed priming with ZnSO4 @ 0.5% for 12 hours could be recommended due to higher yield (7.94 t ha-1 of kharif hybrid maize and 1682 kg ha-1 of lathyrus) and higher net return (Rs.69,904/-ha-1 for maize, Rs.40,327/- ha-1 for lathyrus) as well as highest B:C ratio (2.74 of kharif hybrid maize and 2.94 of lathyrus) for maize-lathyrus in sequence under rainfed situation.

Productivity of lentil in rainfed ecology is very low and crop was infested with different soil and seed born fungal disease. In light of fragment information available on response of seed treatment with Trichodermaharzianum strains S1 and S3, a field experiment was conducted during winter seasons of 2013-14 and 2014-15 at experimental farm of KrishiVigyan Kendra, Buxar and farmers field. Among different seed treatment practices coupled with IRRI BMP, Trichoderma strain S3 produced the highest number of pods/plant (59.6) and 100-grain weight (2.60 g) followed by seed treatment with S1+ IRRI BMP and Thiram+IRRIBMP. However, farmers’ practice recorded lowest value of all these traits. Highest number of nodules/plant (15.80) and dry matter of nodules, (37.12 mg/plant) were recorded under seed treatment with S3+IRRI BMP followed by S1+IRRI BMP and Thiram+IRRI BMP in order. Seed treatment with S3+IRRI BMP recorded highest root length (25.2 cm), root dry weight (0.90 g/plant) and seed yield (13.33 q/ha) followed by seed treatment with S1+IRRI BMP and Thiram+IRRI BMP in order. However, farmers’ practice recorded minimum value of these traits. Economic analysis of data showed that maximum net return (Rs 23489/ha) and cost-benefit ratio (2.42) was recorded under seed treatment with strain S3+IRRI BMP followed by seed treatment with S1+IRRI BMP and Thiram+IRRI BMP. However, minimum economic return was recorded with farmers’ practice.

Background: Chickpea is a second most important pulse crop grown in 56 countries and India rank first in production which shares 61.4% of the total world chickpea production however, productivity is very low as compared to other countries. Therefore, varietal development with inherent tolerance to biotic and abiotic stress is the prime objective to improve component productivity traits to get better yield in rainfed agro-climatic conditions.Methods: Ninety germplasm accessions of chickpea along with four check viz., JG 14, JG 16, JAKI 9218 and Radhey were evaluated in augmented block design at experimental research farm of Banda University of Agriculture and Technology, Banda, Uttar Pradesh, India. Phenotypic data were subjected to study the genetic parameters and association analysis of yield and its component traits using SPAR 2.0 Package and Windostat Version 9.2.Result: The significant variation was observed for all the traits except number of secondary branches, number of pod per plant, number of seeds per pod among the genotypes. The maximum GCV and PCV was observed for height of first pod (35.28 and 39.29), followed by seed yield per plant (29.77 and 40.32) and number of primary branches (25.63 and 31.44). The high magnitude of heritability with genetic advance was estimated for seed index (96.61%), while the high genetic advance as per cent of mean was recorded for first pod height (65.27%). The positive and significant association of seed yield with number of pods per plant, seed index, number of seeds per pod, number of secondary branches, number of primary branches and height of first pod indicating the importance of these traits in selection criteria. Path analysis identified that number of seeds per pod, number of pods per plants, seed index and number of secondary branches per plant as highly desirable component for direct effect on seed yield per plant. The genotypes ICVT-181106 had highest selection indices for seed yield followed by ICVT-181107, PUSA-1053, JG-218, GNG-1999, ICVT-181102 and HC-5. Therefore, high GCV and PCV, significant positive direct and indirect correlation and high estimate of selection indices for grain yield can be directly and indirectly used for chickpea breeding program.

Full textAbstract:
Background: Climatic variations such as drought have high level of impingement on the yield of rain-fed crops like mustard. A drought is an extended period of months or years when region notes a deficiency in its water availability. Water stress causes heavy yield losses in Indian mustard (17-94%). Low water availability during stem elongation, flowering and pod development causes reduction of pods per plant leading to reduction in grain yield. Very meagre efforts have been made towards improving drought tolerance of this crop. Hence there is an urgent need for, development of water use efficient genotypes. Drought Susceptibility Index (DSI) is a measure of drought, based on loss of yield under drought conditions in comparison to the yield under normal conditions. It expresses the separate effects of yield potential and drought susceptibility on yields under drought. In these terms, lower DSI is considered synonymous with higher drought tolerance. In view of above facts, present study is aimed at investigating the effects of drought on yield attributing traits with, the objective of identifying Indian mustard genotypes and their hybrids which can withstand water stress with minimum loss in yield. Methods: Nine Indian mustard genotypes and their F1s were evaluated under irrigated and rainfed conditions to study the effect of drought by calculating DSI, on yield and yield traits and to characterize their relative tolerance against drought at the Agriculture Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during Rabi 2017-18 season. Observations were made for different yield and yield related traits. Result: Genotype RB-50 was found as tolerant for seed yield per plant with DSI 0.38 while hybrids RB-50×RH-749 and RB-50×Giriraj were exhibiting tolerant DSI values for siliqua per plant, 1000 seed weight, seed yield per plant and oil content. These parents and F1s would serve as useful donors and hybrids respectively, in mustard breeding programmes for improving drought tolerance.

Background: Urdbean (2n=2x=22), also known as blackgram is an important short duration legume crop belonging to family Fabaceae, widely cultivated in Asia. Urdbean occupies an important position among pulses owing to its high seed protein (25-26%), carbohydrates (60%), fat (15%), minerals, amino acids and vitamins. Owing to its low water requirement, it is also suitable for rainfed conditions. It adapts well to various cropping systems owing to its ability to fix atmospheric nitrogen in symbiosis with soil bacteria, rapid growth and early maturity. Half diallel analysis was adopted in present study to gather information on gca (general combining abilities) and sca (specific combining abilities) of 6 diverse parents and simultaneously estimating various types of gene effects involved in the expression of seed yield and related attributes in urdbean. Methods: The F1’s were developed during 2017 in 9 x 9 half diallel fashion by Sharma et al. 2019 and these F1’s were evaluated. Significant crosses on the basis of gene action and combining ability were selected for further advancement. The experimental material comprised of the six parents and 15 F2’s of a 6 x 6 half diallel cross among six cultivars of urdbean (four are purelines viz., Palampur-93, HPBU-111, DU-1 and KU-553 and rest of the two are advanced and indigenous lines viz., Him Mash-1 and IC-281994). The F2’s along with the parental genotypes were grown in a Randomized block Design (RBD) with three replications at Experimental Farm of the Department of Crop Improvement, COA, CSK HPKV Palampur (H.P.) during Kharif, 2018. Results: The cross combination, Him Mash-1× HPBU-111, was identified the best for high seed yield on the basis of sca. The specific crosses, Palampur-93 × IC-281994, Palampur-93 × KU-553 were good specific combiners for most of the traits viz., plant height, branches per plant, pods per plant, biological yield per plant, seed yield per plant, harvest index, 100-seed weight and crude protein content.
