Effect of cultural management practices and weather factors on sorghum stalk rot in Mindanao [Philippines]
1986
Tangonan, N.G. | Quimio, H.
Two sorghum croppings, a main and a ratoon crop, were used to determine the effect of various cultural management practices and prevailing weather conditions on the occurrence and development of sorghum stalk rot. Except for lesion length, no other disease parameter was significantly influenced by tillage practice. Deep field plowing and weeding apparently limited the lesion size or infection severity on sorghum plants regardless of NPK levels applied and population density. Grain yield of sorghum in both croppings was higher where a maximum tillage supplemented with hand weeding was employed. Weather factors, such as high temperature and high rainfall, slowed down infection rate whereas high relative humidity and longer sunshine increased infection rate but not beyond the optimum levels
