Abstract:
A field experiment to study the comparative performance of urea and
neem coated urea on the yield and yield attributes of rice variety-Triveni was
conducted at the College of Agriculture, Vellayani, Kerala during Virrippu season
of 1973. The treatments consisted of four levels of nitrogen (0), 40, 80 and 120
kg N/ha) and five methods of applications ie. (1) full basal urea (2j full basal neem
coated urea (3) 75% basa! urea -I- 25% urea as top dressing (4) 75% basal urea
4- 25% neem coated urea as top dressing, and (5) 75% basal neem coated urea +
25% neem coated urea as top dressing. It was found that the number of panicles
per square meter, 1000 grain weight and yield of grain and straw were increased
by nitrogen application. The application of 40 kg nitrogen as neem coated urea
was found to be equivalent to 80 kg nitrogen as urea as far as the yield of
grain was concerned. The results showed that rieem cake can be profitably used
to increase the efficiency of urea applied to wet land rice.
