This book was released on 2001 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: This experiment was conducted during the 1999 and 2000 growing seasons at the Iowa State University Sorenson Farm located southwest of Ames, Iowa and at the Iowa State University North Central Research and Demonstration Farm located south of Kanawha, Iowa. The experimental design for both locations was a randomized complete block with a split-split-split plot design and three replications of each treatment. Treatments included three planting dates, three hybrids, two row spacings, and two fertility regimes. Whole plot treatment was planting date and split plot treatments were hybrid, row spacing, and fertility regime. Significant difference was found between row spacing treatments for yield with the June planting dates in 1999 with 38-cm row spacing yielding more than 76-cm row spacing. Significant difference was not found between row spacing treatments for yield at the other planting dates in 1999 or in 2000. As planting date was delayed, weight kernel−1 decreased at both locations in both years. Starter fertilizer produced significantly higher yields in 1999, with a cold and wet spring, but not in 2000 with a warm and dry spring. Producers should rely on calendar date recommendations in determining optimum planting date. Planting dates between late April to early May should result in maximum yields in most years. Starter fertilizer may provide benefits during a cold and wet spring as well in situations of a low soil test for P or K.

Download or read book The Effects of Planting Date, Nitrogen and Boron Application on Mineral Element Concentration, Yield, Dry Weight and Fresh Weight of Sweet Corn written by Jonathan Anthony Sisson and published by . This book was released on 1981 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of planting date on mineral element concentration in sweet corn (Zea mays L. cv. Jubilee) at six developmental stages and on yield were investigated. Planting dates were chosen to correspond to early, mid-season, and late commercial plantings. Two nitrogen rates were applied since nitrogen is more often limiting than any other nutrient for sweet corn grown in Western Oregon. Boron was also applied since it has been shown to be limiting in many other crops grown in the Willamette Valley. Planting date significantly affected N, P, K, Ca, Mg, Mn, Fe, Cu, B, and Zn concentration in the whole plants during the vegetative growth stages and in the ear leaves during the stages between tasseling and harvest. During the early stage of growth, N, P, K, Ca, Mg, B, and Zn tended to be higher in the early planted corn plants, while later in the development of corn the effects of planting date were more variable. Planting date also affected the fresh and dry weight of whole plants; the later planting produced more dry weight than the earlier two plantings, while the early planted corn produced more fresh weight at harvest than the later two plantings. Consequently, when analyzing sweet corn for nutritional status, date of planting should be considered when interpreting the plant analysis data. The application of B had no effect on yield, fresh weight or dry weight and only increased B concentration at the first developmental stage. The additional application of N, did not significantly increase yield for the late planted corn, but did for early planted corn. N concentration, as well as Mg, Mn, Cu, and Zn concentrations increased with the higher rate of N fertilizer applied (125 kg/ha). Fresh weight and dry weight were both higher in the plants receiving the higher rate of N, with the difference becoming greater as the plants matured.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Water stress and heat stress are considered to be two primary factors that limit crop production in many parts of the world. Global warming appears to be increasing the water requirements of plants. Understanding the impact of water deficit on plant physiological processes and efficient water management are of great concern in maintaining food production to meet ever increasing world food demand. The book addresses various climatic soil and plant factors that contribute to the water use efficiency in plants subjected to water stress. It covers all issues related to soil, plant and climatic factors that contribute to the crop responses to water stress. The books advances the knowledge in improving and sustaining crop yields in ever increasing unpredictable climatic fluctuations This book uses crop simulation models for response of crops to limited water under various management and climatic conditions.
