Selecting Corn Hybrids
Corn is physiologically mature when kernels reach maximum dry weight and are safe from frost. All milky fluid disappears from the kernel, and the black layer, a dark layer of cells, forms near the tip of mature kernels. Most hybrids adapted to Wisconsin reach this stage when kernel moisture decreases to 30–32%, but it may not occur until moisture content decreases to 28% for some early hybrids....
متن کاملRanking Corn Silage Hybrids
Corn hybrids for silage vary in yield and several quality traits that affect farm profitability, which is the prime criterion on which hybrids should be ranked. The partial budget approach is the only way to rank corn hybrids for silage for individual farms according to their effects on farm profits. Partial budgets consider only those costs and returns that change in response to the corn hybri...
متن کاملForage Yield and Silage Quality of Dual-Purpose Corn Hybrids in Two Levels of Urea Fertigation
The experiment was completed to evaluate the responses of forage yield and silage quality of dual-purpose corn hybrids to urea fertigation. For this purpose, two studies were conducted each as a split plot experiment based on a randomized complete block design with three replications at two locations in research farms of College of Agriculture, Isfahan University of Technology, Isfahan, Iran, i...
متن کاملEvaluation of selection indices for drought tolerance of corn (Zea mays L.) hybrids
Drought is one of the major problems affecting crops production, including corn, in many parts of Iran. In order to detect drought tolerant grain corn hybrids, an experiment with twenty corn hybrids was conducted during 2006 in Qom Province, Iran, using a complete randomized block design with four replications, under optimal moisture and drought stress condition. Results showed diversity among ...
متن کاملEffect of drought stress and application of clinoptilolite on yield and quality of silage corn hybrids
Present study was carried out to evaluate the effects of drought stress and clinoptilolite on the yield and forage quality of silage corn hybrids. The experiment was arranged in a three-replicated split-spilt plot based on randomized complete blocks design (RCBD) with three irrigation regimes including optimum irrigation, moderate and severe drought stress (irrigation after 70, 100 and 130 mm e...
