Book Description
Research in varied experiment at different locations showed that management markedly influenced corn production for silage. Work was conducted to relate these various management factors to silage production in an experiment repeated across locations. Studies were conducted at two locations in the Coastal Plain region, and at one locative each in the Peidmont, Limestone Valley, and Mountain regions. The objective were: (1) to determine the effects of plant populations, nitrogen (N) rates, and hybrids on production and quality of corn for silage; and (2) to relate these results to those in previous experiments. The results can be summarized as follows: 1. Maximum yields were produced with populations of 28,000 plants/acre under optimum management, but ar lower populations when soil moisture was limiting. However, the higher plant populations never reduced yields compared to lower populations, so even in the case of droughtty soils the higher population of 28,000 plants/acre could be planted to take advantage of seasons with good rainfall distribution. 2. Forage quality was maintained ar populations of 28,000 corn plants/acre. The general trend, although not always significant, was for digestibility (IVDMD), percentage ears, and percentage protein to decrease and percentage stalks and fiber to increase in the forage with a population increase. 3. Nitrogen rates of 150 pound/acre produced maximum yields (...).
