Influence of moisture regimes on growth parameter, yield attributes, and yield with sowing methods of wheat (Triticum aestivum L.) cultivar

Abstract

A field experiment was conduct at Agronomy Research farm, Acharya Narendra Dev University of Agriculture and Technology, Kumarganj, Ayodhya, (U.P.) during Rabi season of two combined year of 2017-18 and 2018-19 with an objective of to find out the suitable wheat two varieties with moisture regime and different sowing method system. Eighteen treatment combination consisted of two wheat variety (PBW-343 and HUW-234) and three moisture regimes (irrigation at 0.8 IW/CPE, 1.0 IW/CPE ratio and irrigation at CRI late jointing and flowering stage allotted in main plots and three sowing methods system (Broad casting, seed drill and FRIB) in sub-plots. The experiment was conducted in split plot design (SPD) with 3 replication on silty loam soil having low organic carbon (0.33% and 0.32%) and available nitrogen (137.60 kg ha-1 and 136.82 kg ha-1) medium in phosphorus (15.20 kg ha-1 and 14.70 kg ha-1) and available potassium (249.30 kg ha-1 and 248.32 kg ha-1) and soil pH is high (8.30 and 8.20). The crop was show on November 25 in the first and second both years, respectively using a seed rate of 125 kg ha-1 with row sowing of 22.5 (cm) apart. The crop was harvest on April 17 and April 19 during 2018 and 2019 respectively. The growth parameters character like plant height (cm), dry matter accumulation (gm-2), LAI as well as attributing are spike length (cm), number of grain Spike-1, test weight (g) were found significantly high with variety PBW-343along with moisture regime 1.0 IW/CPE and wheat sown by FIRB (Furrow irrigation raised bed) method over rest of the treatments during both year. The biological yield were also followed the same trend as of growth and yield attributes during both the year. The highest gross income (₹ 125203.80 and 134785.75 ha-1), net return (₹ 91728.80 and 98485.75 ha-1) and benefit: cost ratio (2.74 and 2.71 ₹-1 invested) was obtained with the PBW-343 and Irrigation at 1.0 IW/CPE ratio along with furrow irrigated raised bed method during 2017-18 and 2018-19, respectively.
