This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In Kansas, productivity of grain sorghum [Sorghum bicolor (L.) Moench] is affected by weather conditions at planting and during pollination. Planting date management and selection of hybrid maturity group can help to avoid severe environmental stresses during these sensitive stages. The hypothesis of the study was that late May planting improves grain sorghum yield, growth and development compared with late June planting. The objectives of this research were to investigate the influence of planting dates on growth, development, and yield of different grain sorghum hybrids, and to determine the optimal planting date and hybrid combination for maximum biomass and grains production. Three sorghum hybrids (early, medium, and late maturing) were planted in late May and late June without irrigation in Kansas at Manhattan/Ashland Bottom Research Station, and Hutchinson in 2010; and at Manhattan/North Farm and Hutchinson in 2011. Data on leaf area index, dry matter production, harvest index, yield and yield components were collected. Grain yield and yield components were influenced by planting date depending on environmental conditions. At Manhattan (2010), greater grain yield, number of heads per plant, harvest index, and leaf-area were obtained with late-June planting compared with late May planting, while at Hutchinson (2010) greater yield was obtained with late May planting for all hybrids. The yield component most affected at Hutchinson was the number of kernels panicle-1 and plant density. Late-May planting was favorable for late maturing hybrid (P84G62) in all locations. However, the yield of early maturing hybrid (DKS 28-05) and medium maturing hybrid (DKS 37-07) was less affected by delayed planting. The effects of planting dates on growth, development, and yield of grain sorghum hybrids were found to be variable among hybrid maturity groups and locations.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sorghum [Sorghum bicolor (L.) Moench] is a relatively drought- and heat-tolerant cereal crop. Global demand and consumption of agricultural crops for food, feed, and fuel is increasing at a rapid pace. To satisfy the growing worldwide demand for grain, production practices must be well optimized and managed. The objectives of the present study were: to optimize sorghum production by determining the best management practices (planting date, row spacing, seeding rate, hybrid maturity) for growth and yield, to evaluate the agronomic responsiveness of grain sorghum genotypes to nitrogen (N) fertilizer and to develop a partial financial budget to N fertilizer application based on best management practices. In order to meet these objectives, field experiments were conducted in 2009, 2010 and 2011 at Manhattan, Belleville, Ottawa, Hutchinson, Hays, at KSU Experiment Stations and Salina, and Randolph at Private Farms. Results indicated that early planting date (late May) and narrow row spacing (25 cm) providing the most equidistant spacing, produced better plant growth, light interception, yield components (number of grains per panicle, 300-grain weight), and biological yield. Results indicated that with increasing N rate, there was a proportional increase in chlorophyll SPAD meter reading, leaf color scores and number of green leaves. There was a significant difference among hybrids for N uptake, NUE and grain yield. However, there was no effect of N and no interaction between N and hybrid on grain yield. Over all, the genotypes with high NUE also had higher grain yield. Economic analysis using partial budget indicated that all N levels had positive gross benefit greater than control at all locations. However, the response varied across locations. Our research has shown that sorghum responds to changing management practices and opportunities exist to increase grain yield by optimizing planting date, seeding rate, row spacing, N application and selection of genotypes.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Grain sorghum (Sorghum bicolor L.) is an important crop to Kansas agriculture, and Palmer amaranth (Amaranthus palmeri S. Wats.) is considered the most troublesome weed in grain sorghum. In 2019, field experiments were conducted near Manhattan and Hutchinson, Kansas to determine the influence of grain sorghum planting dates and Palmer amaranth emergence timings on competitive outcomes. Grain sorghum was planted on June 3 and July 1 at Manhattan and May 17 and June 17 at Hutchinson. Natural populations of Palmer amaranth were established at an early and late emergence timing relative to crop planting along with a weed-free treatment. Palmer amaranth was thinned and maintained at a target population of 4 plants m−1 of row. The growth stage and height of grain sorghum and Palmer amaranth were recorded weekly. Biweekly up to grain sorghum flag-leaf stage, two grain sorghum and two Palmer amaranth plants plot−1 were harvested to measure leaf area and biomass. Grain sorghum was harvested to measure yield and seed weight. Late planted grain sorghum accumulated height, leaf area, and biomass more quickly than early planted grain sorghum on a time scale of days after planting (DAP) at both locations. On a scale of growing degree units (GDU), grain sorghum leaf area and biomass accumulation at Manhattan were similar across planting dates, while the late planting accumulated more height. In Hutchinson, grain sorghum leaf area accumulation was similar across plantings, while the late planting accumulated height and biomass more quickly on a GDU scale. Palmer amaranth density in both sites were less than desired and inconsistent, therefore, it was impossible to test the effects of Palmer amaranth emergence timing. In Manhattan, grain yields were similar across treatments, excluding the treatment with the highest Palmer amaranth density (1.5 plants m−1 of row), and seed weight was greater in the early planting than the late. In Hutchinson, grain sorghum yield was 37% less in the early planting than the late planting, due to poor crop establishment in cool soil temperatures after planting, and poor pollination and grain fill during hot and dry conditions. Later planted grain sorghum grew faster than early planted grain sorghum, thus was more competitive against weed competition in early growth stages. This research demonstrated a potential tactic that a producer could implement to enhance early season competitiveness of grain sorghum against Palmer amaranth.

Available in PDF, EPUB and Kindle. Book excerpt: Interest has grown regarding management options to improve and stabilize dryland corn production (Zea mays L.) in challenging environments. Grain sorghum (Sorghum bicolor L.) has been documented to produce more consistent grain yields than corn in dryland production in Kansas. In periods of reduced water availability, sorghum can delay growth and development, allowing the plant to capture water later in the season for flowering and grainfill. Delaying planting in corn can serve a similar purpose. In central Kansas, planting corn earlier so pollination occurs before periods of extreme stress has been successful, but little research has investigated delayed planting or its long-term effect. The objectives of this study were to evaluate plant growth and yield response to delayed planting through field research and to quantify its long-term effects through crop model simulations. Field trials with delayed planting dates and hybrids of varying maturity revealed that yield at Manhattan, KS, did not decrease significantly until the final planting date in 2007 and did not decrease at all with delayed planting in 2008. At Belleville, yield increased with later planting in 2007 and was not affected by planting date in 2008. At Hutchinson, yield decreased significantly with each planting date until the third in 2007. However, in 2008, yield increased significantly from the second to fourth planting dates. Simulations in CERES-Maize over 51 years revealed no difference in yield between planting dates at Manhattan and Belleville, but showed a significant decrease between the first planting date and the third and fourth planting dates at Hutchinson. Chi-squared tests indicated that all planting date x hybrid combinations at Manhattan and Belleville produced economically profitable yields at frequencies significantly greater than 0.5. At Hutchinson, all but two of the twelve planting date x hybrid combinations produced profitable yields at frequencies significantly less than 0.5. The two remaining combinations produced profitable yields at frequencies that were not different than 0.5. One of these combinations was observed at the fourth planting date. These results suggest that the economical viability of delayed planting of corn is heavily dependent on location.
