ASSESSMENT OF DOABLE TECHNOLOGIES FOR ENHANCINGTHE YIELD POTENTIALS IN SUNFLOWER (HELIANTHUS ANNUUSL.) UNDER RAINFED CONDITIONSK. Prabhakar, K. Venkataramanamma, B.V.P. Reddy , R. Narasimhulu, D. Satish Kumar,S. Neelima and N.C. VenkateswarluAbstract Cluster FLDs were organized by AICRP on sunflower scheme, Regional Agricultural Research Station,Nandyal during three consecutive years of 2018-19, 2019-20 and 2020-21 in an area of 50 ha at 66 locations.At every demonstration site improved management practices viz improved sunflower hybrid with high oilcontent (Prabhath), thinning at 10 days after sowing boron spray @0.2% at ray floret stage and need basedplant protection measures were demonstrated against viz., farmerâs practice of sunflower cultivation. Thesunflower yields under demonstration practice higher than farmer practice in all the three years. Thepercentage increase over farmers practice was lowest 13.3% during 2020-21 and highest 25.6 during 2018-19 with an average increase of 20.7 per cent observed in demonstration practice. The average gross returnsof three years were Rs. 92477/- per hectare in demo practice which is 19.7 per cent higher than the farmerspractice (Rs. 72262/- per ha.). The net returns of Rs.65393/- per hectare was recorded under demonstrationpractice and it was 26.9 per cent higher than the farmer practice (Rs. 51528/- per ha.). The mean benefit costratio of three years of demonstration practice higher (1:3.2) than farmer practice (1:2.96). |
