Abstract
Field experiments were conducted at
three research farms of Cotton Development Board located at Sreepur, Sadarpur
and Jagadishpur to determine the effect of various combinations of organic and
inorganic source of nitrogen on cotton yield and yield contributing characters
in 2013-2014 growing period. The performance of five N sources viz. 100% N from
urea, 90% N from urea + 10% N from poultry manure, 80% N from urea + 20% N from
poultry manure, 70% N from urea + 30% N from poultry manure and 60% N from urea
+ 40% N from poultry manure were evaluated. The effect of N sources was found
significant for number of primary fruiting branch and number of boll per plant.
Besides the interaction effect of location × treatment was found significant
for individual boll weight and seed cotton yield. Results revealed that that
application of 40% N from poultry manure at Sreepur farm and application of 30%
N from poultry manure at Sadarpur and Jagadishpur farm were comparable to 100%
of N from urea only in respect of producing seed cotton yield.
Key words: Organic
fertilizer, Inorganic fertilizer and Cotton yield.
