Title StatementIncidence of stalk rot on corn as influenced by different agronomic practices
General NoteKabacan, North Cotabato: USM, 1986. 94p
Summary, Etc.The study was conducted to determine the effect of population density, tillage practices, weed control and soil fertilization on the occurrence of stalk rot on corn and to evaluate the effect of stalk rot on corn yield. Occurrence and severity of stalk rot were assessed five days after inoculation and thereafter until 15 days. Findings revealed that the percentage occurrence and severity of stalk rot during wet and dry seasons were not significantly affected by the variety of corn used, population density, tillage, weed control, and soil fertilization. Yield of corn, however, was significantly affected by these practices. Higher infection was manifested at plant population of 90,000/ha both on wet and dry season trials. A plant population density of 80,000/ha gave the highest mean yield of 5633.66 kg/ha and 4721 kg/ha in the wet and dry season trials, respectively. In tillage practices, the highest infection was observed in plots which involved off-barring and hilling up operations. Plots with off-barring plus handweeding and hilling up produced the highest mean yield of 3371.64 kg/ha and 4155.33 kg/ha in wet and dry season trials, respectively. In different weed control practices tested, the highest mean yield was obtained from handweeded plots with 5519.49 kg/ha and 5683.20 kg/ha in wet and dry season trials, respectively. The lowest yield was obtained from the unweeded plots with 2323.16 kg/ha in wet season and 3040.81 kg/ha in dry season. Plots applied with nitrogen alone or in combination with phosphorous or potassium had higher degree of infection. However, yield of corn was significantly increased with the application of the fertilizer
