Abstract

Field experiments were conducted on vertisols during North East monsoon season of 2001-
2002 and 2002-2003 under rainfed condition to study the effect of insitu moisture conservation and integrated nutrient management on growth and yield of sunflower. The experiments were laid out in split plot design with three replications. Main plot consisted of three different insitu moisture
conservation methods, whereas in sub – plots integrated nutrient management practices were
taken. The experimental results revealed that sowing of sunflower on broad bed and furrow in
combination with application of 75% N through inorganic + 25% N through CCP + Azophos + 0.2% boron spray favourably increased the growth and yield attributes which in turn increased the seed and stalk yield of sunflower. Magnitude of increase of seed yield of sunflower was of 22.1 to 26.4 per cent over RDN as inorganic fertilizer application. Similarly the increase in grain yield in
BBF was 27.3 to 30.0 per cent over flat bed method.
