EFFECT OF N-LEVEL AND ITS TIME OF APPLICATION ON GROWTH CHARACTERS OF SOME RICE VARIETIES
Soil and Water Research Institute, Agricultural Research Centre, Giza, Egypt
Abstract
Two field experiments were conducted in 1988 and 1989 seasons at Al-Khadmia, Kafr El-Sheikh Governorate to study the effect of five levels of nitrogen and three times of its application on the growth characters of two rice varieties, namely, Giza 181 and Giza 175. Over two seasons, Giza 181 surpassed Giza 175 in most of growth characters, while Giza 175 gave the largest number of panicles/m2. Ascending N-levels up to 60 kg N/fed. as half of N on dry soil and the other half of N at 20 days after transplanting significantly increased most of growth characters. The interaction between rice varieties, N-levels and its time of application significantly affected different growth characters under study.
