Effect of integrated nutrient management techniques on yield attributes and yield of sunflower (Helianthus annuus)
Year: 2001
Type: article
Abstract: An experiment was conducted during 1995-97 to develop integrated nutrient management package for sunflower (Helianthus annuus L.), with.2 types of organic sources, viz. farmyard manure (FYM) and P-enriched FYM, inorganic nutrients and biofertilizers. lntegrated application of either FYM or P-enriched FYM combined with Azospirillum and phosphobacteria and borax spray in addition to recommended NPK alone gave the highest yield. On-farm experiment showed that integrated application gave 29% higher yield than recommended NPK. lntergrated nutrition using P-enriched FYM was found to be effective, considering the benefit : cost ratio. Highest benefit : cost ratio was obtained with integrated application of P-enriched FYM, inorganic fertilizers and biofertilizers compared to application of NPK alone.
