EFFECT OF DIFFERENT LEVELS OF N·FERTILIZERS ON THE YIELD AND QUALITY OF MAIZE

M. Sarwar

Open publisher page 3 citations

Abstract

The experiment was carried out to study the effect of 4 nitrogen levels on grain yield and quality of maize. The yield with 200 kg nitrogen ha·1 was 7130 kg ha·1 but was 5450 ha·1 without nitrogen. The increase in yield with 100 and 150 kg nitrogen ha·1 was statistically at par but significantly lower from that with 200 kg nitrogen ha'. The oil and protein contents were significantly increased with the successive increase of nitrogen, maximum being at 200 kg nitrogen ha·1.
