Abstract:
Field experiment was conducted at AICRP on Water Management, Belavatagi, UAS, Dharwad, during 2013-14 to 2014-15 on soil deficient in available micronutrient to study the Yield, water use and economics of sunflower (Helianthus annuus) as influenced by irrigation and integrated nutrient management. The crop receiving irrigation level at 0.8 IW/CPE recorded significantly higher sunflower yield (18.14 q/ha), gross income (Rs.58, 968 /ha), net income (Rs.43,593) B: C ratio (3.84) during 2013.However, such significance was not observed during 2014 and in pooled analysis. Among different nutrient combinations, RPP (RDF+ FYM) treatment also recorded higher gross returns (Rs. 69,247) and net returns (Rs.50,519) B:C ratio (3.73) and WUE (5.97) in pooled analysis. The interaction effect between irrigation and nutrient level showed that, the treatment received RPP with 0.8 IW/CPE recorded significantly higher grain yield (21.5 q/ha) and economics. The higher B:C ratio (3.94) and WUE (6.37 kg/ha. mm) was observed with irrigating at critical stages with RPP treatment combinations.
