- Abstract
Front line demonstrations on cumin consisting of two improved varieties (GC-4 and RZ-209) with scientific interventions viz., seed treatment (Bavistin @2.5 g kg-1 seed and Trichoderma viride @4 g kg-1 seed), and pre-emergence application of oxadiragil (Raft) @75 g a.i. ha-1 for effective weed management and application of recommended doses of nutrients (40:40:0 kg ha-1 NPK) for balanced nutrition and appropriate plant protection schedule [(Two sprays of malathion (0.2%), two sprays of Dithan M-45 (0.2%) and one spray of karathan (0.1%) for the control of aphids, blight and powdery mildew, respectively)] were carried out at farmers' fields in two villages (Kajipura and Bhadal) of Jaipur and one village (Karad) of Sikar district of Rajasthan during Rabi season of 2011-12 and 2012-13. Study revealed that overall yield was increased by 21.09% over farmers' practice due to the technological interventions with average yield of 536.50 kg ha-1. Overall extension gap of 112.50 kg ha-1 and technical gap of 463.50 kg ha-1 were recorded in the study with 46.35% technology index. Maximum additional return (Rs. 15,875 ha-1) with highest effective gain (Rs. 10,775 ha-1) and incremental B: C ratio (3.11) were obtained in the year 2011-12. However, the overall average additional return was Rs. 14601 ha-1 with effective gain of Rs. 9,401 ha-1 and incremental B: C ratio of 2.81.
