Abstract:

The yield of short-season hybrids is lower than long-season hybrids, mainly as a result of the low final leaf area developed by the short-season plants. This is due to the smaller plant stature and smaller leaf number and size of short-season adapted hybrids. In addition, in short-season areas the thermal-time available may be insufficient to mature grain of current maize hybrids. Maize hybrids which accumulate leaf area quickly, mature earlier, yield well and tolerate higher population densities better than the currently available hybrids would be more suitable for production in short-season areas. The "Leafy reduced-stature" maize hybrids, which have only recently been developed, have traits which address these criteria. There has been no previous effort to evaluate the effects of more than two plant population densities or the effects of planting patterns on the yield, yield components and vegetative growth of these hybrids. in 1995, field experiments were conducted at two sites near Montreal to compare the response of leafy reduced-stature (LRS), non-leafy normal stature (NLNS), and non-leafy reduced-stature (NLRS) maize hybrids to plant population densities and planting patterns. LRS maize hybrids showed the most rapid growth of the first ear, and the highest yield per single plant and per hectare at high plant population densities in paired rows. LRS hybrids also had longer grain filling periods, lower grain moisture contents and higher harvest indices than conventional (NLNS) hybrids. Rapid growth of the first ear and a higher harvest index are indications that LRS hybrids should be more tolerant of higher population densities than currently available hybrids. Therefore, LRS hybrids show promise for production in short-season areas at high plant population densities where maize cultivation is not currently economical due to shortness of the growing-season.

Abstract:

Studies were conducted to determine if corn stalk strength had an effect on southwestern corn borer (Diatraea grandiosella Dyar) survival during different growth stages. In 2006 southwestern corn borer larvae were placed on corn during the tassel stage near the ear and base of the plant. Survival was higher near the ear than near the base of the plant. In 2007, five varieties of corn were planted at three locations in Mississippi. Plants were infested with five 3rd instar larvae at the ear zone during tassel, dough and dent development stages. After five days stalk strength and borer survival were measured. Survival decreased as the corn progressed from tassel to dent stage. Survival varied among corn varieties. The relationship between stalk strength and borer survival was not consistent, indicating that there are likely factors more directly limiting borer survival than physical stalk strength.

Abstract:

Studies of corn root morphology, canopy description, light and nutrient relationships, have focused on conventional corn hybrids. We are now extending these studies to other corn types with contrasting canopy and root architectures. Field and greenhouse experiments were carried out in order to characterize root morphology, N status in the plant and its relationship with yield and yield components, canopy architecture and light interception of these genotypes. The indoor experiments investigated root morphology and how N affects it. Root fractal geometry and its relationship with standard measured root variables were investigated. The field research, at two sites and over two growing seasons, examined (i) maize canopy architecture with regard to light interception and (ii) nitrogen effects on grain yield of different maize genotypes. Four genotypic types were included: (i) Leafy reduced-stature, Lfy1rd1 (LRS), (ii) non Leafy-reduced stature, lfyrd1 (NLRS), (iii) Leafy normal stature, Lfy1Rd1 (LNS), and (iv) conventional commercial hybrids, lfy1Rd1. Pioneer 3905 served as the check hybrid for late maturity, and Pioneer 3979, the check for early maturity. The work allowed development of following methods: (i) root sampling for measurement of large root systems, (ii) staining to enhance root contrast for measurement with a scanner-based software system, (iii) sample size determination for SPAD meter readings, and (iv) the design and construction of a mobile and multi-strata device for measurement of light interception. Data were collected for mathematical characterization of canopies (i.e. leaf angle, co-ordinates of the maximum height of the leaf, co-ordinates of the leaf tip), plant N status (SPAD meter readings), light interception, yield and grain yield components. Conventional hybrids generally showed greater root length and surface area than their leafy genotypic counterparts at early developmental stages (i.e. up to 15 days from emergence).

Abstract:

Data were collected on 24 traits to characterize and classify 35 white floury corn (Zea mays L.) landraces collected on native reserves in Ontario. Several landrace x landrace and landrace x inbred crosses were evaluated. Test crosses were made to determine whether the landraces carry the floury-l (fl$ sb1$) allele. Most traits examined exhibited considerable variation among the landraces. Variation was also observed within many of the landraces for ear and cob colour, for endosperm texture and row number. The landraces were grouped into 10 clusters by centroid clustering analysis. Significant heterosis over the mid-parent value was observed in the crosses among landraces. Some crosses between landraces and inbreds yielded more than either parent. Crossing the landraces with the inbreds improved some agronomic characteristics, but disrupted some of the ear characteristics of the landraces. The floury factor responsible for the characteristic endosperm texture of the IAPO landraces was identified as being the dosage dependent fl$ sb1$.

Abstract:

Maize production in short-season environments has at least two critical problems. Firstly, maize grown in short-season areas has lower leaf area indices (LAI) than maize grown in long season areas, due to shorter plant stature and less time for development, which results in reduced leaf number and size. Secondly, in very short-season areas the seasonal thermal-time available may be insufficient to mature grain of current maize hybrids. Therefore development of maize types that accumulate leaf area and mature quickly would increase production of maize in mid- to short-season areas. The leafy (Lfy1) and reduced-stature (rd1) genes make contributions to this end. However, these two genes have not previously been combined. From 1991 to 1993, field experiments were conducted to evaluate the leafy reduced-stature (LRS) inbred lines and hybrids for yield, maturity times and morphological traits, at different planting densities and patterns in Montreal and Ottawa. LRS maize inbred lines showed the most rapid silk extrusion, optimum leaf area development, and rapid growth of the first ear, the highest yield per unit leaf area, and the closest synchronization of pollen shed and silk extrusion at high plant population densities. LRS maize hybrids had the most rapid leaf development, longest grain filling period, lowest grain moisture content at harvest, and highest harvest index. Therefore LRS hybrids should allow an extension into shorter season areas where it can not now be successfully cultivated, and may increase yields in mid- to short season areas where maize is now produced.

Abstract:

This research focuses on the study of Egyptian corn-mummies. The aim is to systematically record and analyse this class of objects in terms of form, decoration, representational theme, archaeological and cultural context, chronology and use. The present catalogue comprising 91 specimens (over 10 of which have not been previously studied) makes it possible to define the artefacts as mummiform objects, 35-50 cm long, made from a mixture of earth and grain, wrapped in resin-soaked linen bandages and often provided with Osirian wax mask and four small packages interpreted as the Sons of Horus. The mummies, identified as representation of Osiris, are commonly placed in decorated wooden falcon-headed coffins which are the main key for dating the objects to a period between the late Third Intermediate Period and the early Ptolemaic Period. Tehne, Meydum, El-Sheik Fadl, Tuna el-Gebel and Wady Qubbanet el-Qirud are the necropolises where the corn-mummies have been found. They have been chosen in view of the strong association of Orisis with the local cult. These data form the basis of the interpretation in the light of literary, pictorial and archaeological related evidence, associated religious beliefs and symbolic concepts. Corn-mummies illustrate the complex relationship between grain, embodying the idea of renewal as living substance whose life and death follows a cyclic pattern, and the notion of rejuvenation through the figure of Osiris. The sprouting of the grain represents a striking manifestation of the forces of rebirth and growth under the control of Osiris, the imperishable principle of life. It follows that the process of assembling grain and earth in the shape of Osiris ought to be considered not as a mere process of manufacturing grain packages but as a ritual involving the preservation of the cosmic cycle of death and rebirth, the maintenance of the Creative Order.

Abstract:

An incubation study was conducted to evaluate the effects of added urea, NH$ sb4$Cl, and KCl on fixation of NH$ sb4 sp{+}$ and K$ sp{+}$. A field study was carried out to observe the effects of rates and methods of added urea and KCl on the forms and distribution of N and K in soils, and on yields and nutrient uptake of silage corn.
Generally, the fixation of NH$ sb4 sp{+}$ was increased by added N but reduced by added K and vice versa. One exception was that added K increased NH$ sb4 sp{+}$ fixation when NH$ sb4$Cl was the N source. In comparison with NH$ sb4$Cl, urea resulted in greater K$ sp{+}$ fixation but less NH$ sb4 sp{+}$ fixation.
Band placement of urea and KCl showed apparent accumulation of NH$ sb4$-N and NO$ sb3$-N, and exchangeable K$ sp{+}$ in the fertilizer bands, particularly early in the growing season. On the other hand, band placement resulted in lower levels of available N and K in soil between the bands in comparison with broadcast.
Yields of silage corn and nutrient uptake values were increased by N and K fertilizers, except for one soil in the first year. Band placement of urea was superior in the case of frequent and light rainfall but inferior with dry surface soil conditions followed by a relatively large rainfall 3 or 4 days after application. In the latter condition, banding K resulted in less yields on one soil, and banding the two fertilizers together further reduced N utilization on another soil.
Additions of K suppressed Ca and Mg uptake but did not influence N uptake, whereas K uptake was usually enhanced by added N.

Abstract:

Field corn, Zea mays L., has been introduced to the market with pyramided Bacillus thuringiensis (Bt) corn technologies. These technologies reduce kernel damage from ear feeding caterpillar pests, including corn earworm, Helicoverpa zea (Boddie). The first generation Bt traits in field corn demonstrated limited activity on corn earworm feeding on grain in ears. The pyramided corn technologies have greater cumulative protein concentrations and improved expression throughout the plant, so these corn traits should provide an effective management tool against these pests. In addition, reduced kernel injury may also have a direct effect on physical grain quality. The results for this trial showed no relationship between number of damaged kernels and yield was observed for corn hybrid expressing the Herculex^®, YieldGard^®, or Genuity VT Triple Pro^® technologies. A significant relationship between both damaged kernels and test weight and damaged kernels and aflatoxin concentrations was observed in two technologies.

Full text

Abstract:

An experiment was conducted to investigate the effects of N formulation, application rate, and application time on corn yield and quality under Eastern Canadian conditions, to evaluate the hypothesis that application of N will increase corn grain yield and protein concentration without decreasing the total energy content. Three N formulations, each with the rates of 90, or 180 kg ha$ sp{-1}$ were applied at different times. The results indicated that the grain yield increased with increasing N fertilizer rate and with increasing numbers of N application times. N application significantly increased grain protein concentration, on both a per kernel and a dry matter basis, and protein yield. Such as, N application increased the averaged protein concentration, on a dry matter basis, of corn grain by about 8.40% as compared to the control. The protein concentration was not affected by the number of N application times before the plants were 90 cm high. Neither lipid nor non-structural carbohydrate concentration, on both a per kernel and a dry matter basis, were significantly affected by N application in most of the location-years. In addition Near infrared reflectance (NIR) was used to determine the lipid concentration in the aerial corn tissue at different growth stages. The correlation coefficients between the standard analytical method and the NIR method of lipid concentration were all above 0.95, and were significant at 0.01 level.

Full text

Abstract:

The NDSU EarlyGEM or the Early Germplasm Enhancement of Maize (Zea maize L.) is a long term incorporation program designed to increase the genetic diversity of short season hybrids. Starting in 1999, exotic GEM breeding crosses derived from temperate accessions: BR52051, CH05015; tropical accessions: SCR01, CUBA17, FS8B; and tropical hybrid DKB844 along with late checks: B73, Mo17, and Iowa Stiff Stalk Synthetic (BSSS), were adapted to short-seasons and incorporated via a modified backcross (BC) procedure. This study was designed to assess the genetic diversity in exotic derived BC1:S1 lines and their competitive potential as sources of new and unique hybrids. Useful genetic diversity was evaluated with testers belonging to opposite heterotic groups, LH176 representing a non stiff stalk and TR3026 x TR2040 a stiff stalk testers and were tested in five North Dakota environments over two years (2009 and 2010). All the traits showed highly significant (P<0.01) differences across genotypes except root and stalk lodging. Among 236 experimental testcrosses, 64 were statistically not different (LSD, 0.05) to industry hybrids for grain yield. BC derived lines from BR52051, CHO5015, DKB844 showed diverse alleles for low grain moisture (below 87 relative maturity days) at harvest and high grain yield. SCR01, BR52051, CHO5015 and CUBA117 derived lines produced hybrids with high grain oil (4. 9% vs. 4.1%) and grain protein (10.4% vs. 9.1%) contents compared to top checks. The results showed that the exotic incorporations are the sources of unique new alleles for early maturing maize not present in existing US germplasms (e.g. B73, Mo17, and BSSS). Even though each exotic cross was unique to integrate diverse alleles, utilizing multiple unique exotic crosses for incorporation showed large variation for specific traits. Phenotypic correlations of traits showed grain moisture played the most important role for short season hybrid development. Exotic incorporation through NDSU EarlyGEM has shown a new way of breeding early maturing maize keeping the breeding program open and genetic diversity high.

Due to high nutrient soil, K, Mg and S had no effects on corn grain and silage yields. However, there were trends observed in the treatment effects that were significant. Added K at 240 kg K$ sb2$O/ha increased grain yield over zero kg K$ sb2$O/ha in 1983 and Mg at 60 kg/ha increased grain yield over 30 kg/ha in 1984. In silage, 240 kg K$ sb2$O/ha increased yield over 120 and zero kg K$ sb2$O/ha in 1984. Although there was no K by Mg interaction, there was a need for added Mg to achieve higher yields.
The cumulative effect of fertilizer S at 50 kg/ha significantly reduced silage yield in 1984 over zero S treatment indicating that fertilizer S was unnecessary for corn growth by reason of high levels of soil S and sufficient S provided from precipitation and air dry deposition. S had no interaction with K and Mg because there was no need for fertilizer S to increase yields.
The antagonistic association between K and Mg was seen at the seedling, tasseling and silking stages.
There was an indication of a K by S interaction which was expressed at different stages of growth, but this effect was not evident for dry matter yields.

Abstract:

Baby corn (Zea mays L.) consists of unfertilized young ears harvested at silkemergence. The 2011 study was a culmination of four successive years of productionand evaluation of baby corn at Western Kentucky University (36.93 N, 86.47 W). Theobjective was to compare the effect of tassel removal on baby corn (BC) production onfour cultivars of corn, two field (‘N77P-3000GT’, ‘N68B-3000GT’) and two sweet(‘Silver Queen’, ‘Peaches N Cream’). Results indicated that tassel removal gavesignificant increases (P<0.01) of BC ears across harvests (H) and cultivars; however, the effect was not consistent over treatments. For harvests, the difference due to detasseling was significant (P<0.05) for H2 and H3, but not significant (P>0.05) for H1 or H4. For cultivars, numerical values were higher for detasseled than non-detasseled treatments in the first three harvests for each cultivar, but significant (P<0.05) only for ‘Peaches n’ Cream’. Quality of BC from both tassel treatments decreased in H3 and H4. Based upon the increased number of ears resulting from detasseling, additional labor costs would be more than covered. Baby corn has excellent potential as a niche crop for producers and consumers in Central Kentucky.

Abstract:

An experiment was undertaken to determine the effect of tillage and fertilizer on silage and grain corn production and on soil properties as well as to develop a crop yield model. Conventional, reduced, and zero tillage treatments in combination with inorganic or organic (cattle dairy manure) fertilizer treatments were applied yearly on a clay and a sandy loam soil from 1982 to 1986. The best yields were obtained for the combination of zero or reduced-till and inorganic fertilizers. Zero-till resulted in increased soil density and soil water content and a slight accumulation of P and K in the surface layer of the clay soil. Manure improved soil physical properties especially when combined with zero-till, but resulted in lower N availability to the plants. The factors that limited plant yield in the clay site were plant population, soil nitrate content, bulk density and soil water content. Plant population was the only limiting factor in the sandy loam site. A simplified method for predicting corn yields under different management practices was developed.

Abstract:

Cakes were prepared with high fructose corn syrup (HFCS) at 0, 50, and 75% replacement for sucrose by weight of sugar and pregelatinized cross-bonded waxy corn starch added at 0, 0.5, and 1% by weight of flour. The water was adjusted to allow for the moisture content (literature value) of the syrup. Cakes were tested freshly baked, after 3 days of room temperature storage, and after 14 and 45 days of frozen storage (-16°C). The pH, specific gravity, and sugar composition by HPLC were determined for the cake batters. Baked cakes were evaluated for moisture content, volume, and crust and crumb color. Photographs were taken to record the overall appearance. Sensory evaluation of crust and crumb color, moistness, tenderness, flavor, and overall acceptability were completed on all variations after each storage time. The HFCS level and storage time were significant variables. The addition of starch had no effect on the quality of the cakes. Acceptable cakes were made at all levels of HFCS replacement for sucrose. Crust and crumb color were significantly (P < 0.0001) darker and volume was significantly (P < 0.0001) lower for cakes containing HFCS, however, there was little difference in cakes made with the two levels of HFCS (SO and 75%). Storage did lower the overall quality of the cakes, but not significantly in all cases. Moisture content of the cakes stored for 14 days was equal to that of freshly baked cakes. Crust and crumb color continued to darken slightly with storage. A satisfactory cake suitable for frozen storage may be prepared using HFCS.
