Yield and economics of fenugreek (Trigonella foenum graecum L.) as Influenced by irrigation and weed management practices

Abstract

A field investigation was conducted during Rabi season of 2016-17 and 2017-18 at Rajasthan College of Agriculture, MPUAT Udaipur to study the productivity and economic efficiency of fenugreek as influenced by irrigation scheduling and weed management. The treatments comprised 4 irrigation levels (0.4, 0.6, 0.8 and 1.0 IW/CPE ratio) as main plots treatment and 4 weed management (weedy check, pre emergence application of pendimethalin + imazethapyr (RM) 0.75 kg ha-1 in conjugation with one hand weeding 40 DAS, imazethapyr 0.075 kg ha-1 fb one hand weeding 40 DAS and two hand weeding 20 and 40 DAS) as sub plot treatments. The experiment was laid out in a split plot design with 4 replications. The yield attributes, seed and haulm yield of fenugreek were significantly highest when irrigation applied at 1.0 IW/CPE ratio, however, its effect was statistically at par with 0.8 IW/CPE ratio on two year mean basis. The additional income of Rs 25680 and 53090 was realized with 0.8 IW/CPE ratio compared to 0.6 and 0.4 IW/CPE ratio on pooled basis. Significantly more number of number of pods plant-1, number of seeds pods-1, weight of seeds pod-1, 1000 seed weight and seed weight plant-1 as well as seed and haulm yield were recorded with pre emergence application of pendimethalin + imazethapyr (RM) 0.75 kg ha-1 in conjugation with one hand weeding 40 DAS followed by two hand weeding.
