Book excerpt: The objective of this study was to investigate the effect of hybrid and advancing maturity on corn plant quality to simulate corn silage, as measured by feeding trials. Four corn cultivars - brown midrib low lignin cultivar (BM 105), waxy (WX 135), a normal (JX113)-a sister line of the BM 105, and a male sterile type, mix elm, were grown at the Arlington Experiment Farms, Wisconsin, at the population of 88,920 plants per hectare. Entire plants were harvested at 75 percent silk, 23 days post-silking and at physiological maturity. The waxy cultivar produced significantly more dry matter per hectare than the other cultivars. Concnetration of acid detergent fiber (ADF), acid detergent lignin (ADL), neutral detergent fiber (NDF) and crude protein (CP) decreasedsignificantly with advancing maturity in all hybrids. Whole plant forage was dried and fed to goats in conventional 14 by days feeding trials in a complete randomized design. At physiological maturity, the mix elm cultivar was the highest in percent ADF, ADL and lowest in digestibility of DM, ADF, and NDF. O f all the cultivars, the low lignin cultivar was the lowest in concentration of ADF, ADL and ndf and highest in digestibility of DM, ADF and ndf, The normal and waxy cultivars were not significantly different in ADF and ADL concentration and were intermediate in NDF and digestibility. Voluntary intake of pelleted material did not differ significantly between the low lignin, waxy normal cultivars, but was significantly lower for mix elm. (...).

Download or read book Effects of Harvest Date on Sweet Corn Maturity Sugar Content and Yield written by Yueh-mei Wong and published by . This book was released on 1978 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted in 1976 and 1977 on the effects of harvest dates on maturity, yields and sugar content of four cultivars of sweet corn. The cultivars were 'Golden Cross Bantam', 'Jubilee', 'Rapidpak' and 'Tendertreat'. Moisture content of kernels ranged from 80 to 67 per cent for the six harvest dates. A regression technique was used to estimate relationships of yield, percent moisture in kernels and sugar content to the six harvest dates. Relationships of yield and sugar content to percent moisture, content in kernels were also estimated. Yield of husked, acceptable (good) ears, which was used as a standard of yield estimation, was increased by a delay in harvest. The increase averaged 0.135 tons per acre for each day's delay in harvest for three cultivars in 1976 and 0.152 tons per acre per day in 1977. No evidence of linear or quadratic relationships between yield and harvest date were found for 'Tendertreat'. Kernel moisture loss was highly correlated with harvest date and degree hours. Kernel moisture loss averaged 0.687 per cent for each day's delay in harvest in 1976 and 0.577 per cent per day in 1977. Yield increases averaged 0.173 tons per acre for each one percent drop in moisture content of kernels for three cultivars in 1976 and 0.264 tons per acre percent moisture drop of kernels in 1977. Quantitative analysis of sugar content in kernel samples that had been frozen was made by using a gas chromatography technique. Total sugar and sucrose contents dropped most rapidly at early harvests, then decreased slowly. Average rate of sucrose decline was 0.579 per cent for each day of delay of harvest in 1976 and 0.226 per cent per day in 1977. Total sugar decreases averaged 0.589 per cent for each one percent drop in moisture content of kernels in 1976 and 0.304 per cent with each per cent moisture drop of kernels in 1977. Reducing sugar decreased rapidly as harvest was delayed and fructose decreased faster than glucose. There were differences in cultivars in initial sugar content and rapidity of loss as maturity progressed. It appears that a 1:10 ratio of fructose to sucrose may be related to good quality of kernels. The use of the accumulated heat unit system for predicting optimum maturity showed no increase in precision over the use of the number of days from planting to harvest. Proper timing of harvest and selection of cultivars need to be made, as well as giving consideration to other factors, to achieve optimum yields and sugar content of sweet corn.
