| Abstract | ||||
| Two field experiments were conducted at Hada Al-sham Experimental Station, King Abdulaziz University, during two sowing dates (Fall 1994 and Spring 1995) to study the effects of soil solarization (mulching wet soil with clear polyethylene during summer season for the control of soil pests) and different rates of chicken manure as a soil amendment (0, 10, 20 and 40 t/ha) on yield and ear characters and nitrogen uptake by hybrid corn (AGA seed 215 cultivar). The results indicated that values in the Fall was higher than the values in the Spring sowing date in the following parameters: total yield dry matter, weight of 1000 kernels, ear diameter, ear volume, number of kernels/row and weight of ears and its parts (kernels and cobs). However, harvest index was higher in the spring than the fall sowing date. On the other hand, weight of kernels, cobs, and ears shelling %, and protein content of kernels were not significantly affected by sowing date. However, yield and ear characters and their parts were not significantly affected by either soil solarization or chicken manure treatments. Total yield dry matter and nitrogen uptake by corn plants were increased in solarized than in non-solarized soil for both sowing dates. | ||||
