Abstract
The present investigation entitled “Yield and economics of relay cropped Lathyrus (Lathyrus sativus) as influenced by seed treatment and foliar spray of nutrients under rainfed ecology of Chhattisgarh plain.” was carried out during rabi season of 2016-17 at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh, with the objective to find out effect of foliar nutrition and seed treatments on growth and yield of lathyrus under utera system. The soil of the experimental field was Vertisols with low, medium and high in N, P and K, respectively and neutral in reaction. The climate of the region is sub-humid to semi-arid. The experiment was laid out in Factorial Randomized Block Design having the combination of twelve treatments and three replications. The treatment consisted of six foliar nutrients spray and two seed treatments. The experiment was comprised of factor A. Foliar nutrients, F1: Control (No foliar nutrients spray), F2 : 2% Neem Coated Urea spray at branching, F3: 2% Neem coated urea spray at branching and 15 days after 1st spray, F4: 0.5% NPK (19:19:19) spray at branching, F5 : 0.5% NPK (19:19:19) spray at branching & 15 days after 1st spray, F6: 2 % DAP spray at branching & 15 days after 1st spray, and factor B. Seed Treatments, S1: Control (No seed treatment) and S2: Seed treatment with Sodium molybdate @ 0.5 g kg-1 seed. Lathyrus (Lathyrus sativus L.) variety Prateek was sown on 17th October, 2017 with a seed rate of 75 kg ha-1. The crop was harvested on 7th February 2016.Result indicated that among foliar nutrients spray, treatment F5: 0.5% NPK (19:19:19) spray at branching & 15 days after 1st spray, was found effective in enhancing plant height, growth of branches, dry matter production and LAI of Lathyrus which was at par with F6: 2 % DAP spray at branching & 15 days after 1st spray, Factor. F5 : 0.5% NPK (19:19:19) spray at branching & 15 days after 1st spray, was found effective in enhancing number of nodules plant-1 and number of pods plant-1 which ultimately gave the highest yield as well as economic returns. Highest cost of cultivation, gross realization, net realization and B:C ratio as well as energy output, energy output : input ratio and energy use efficiency was found in F5 : 0.5% NPK (19:19:19) spray at branching & 15 days after 1st spray. Highest energy input was obtained under F3: 2% neem coated urea spray at branching and 15 days after 1st spray. Between two seed treatments, S2: Seed treatment with Sodium molybdate @ 0.5 g kg-1 seed resulted in maximum number of plant population m-2, plant height over S1: Control (No seed treatment). Similarly the seed treatment with Sodium molybdate @ 0.5 g kg-1 seed was also gave the higher yield, economic returns, and B:C ratio than S1: Control (No seed treatment).
