Abstract

A two-year field experiments were conducted during the rabi season of 2020–21 and 2021–22 at the Agriculture Farm, Himgiri Zee University, P.O. Sherpur, Chakrata Rd. Dehradun, Uttarakhand, to study theeffect of different dates of sowing, irrigation scheduling, and soil amendments on the yield attributes and yield of wheat (Triticum aestivum L.). The study consists of three irrigation schedulings: viz., I1 (irrigation at 40% depletion from ASM), I2 (irrigation at 50% depletion from ASM), and I3 (irrigation at growth stages) in the main plots, while the three soil amendments S1 (FYM @ 10 t ha-1), S2 (urban compost @ 5 t ha-1), and S3 (vermicompost @ 5 t ha-1) are in the sub-plots with two dates of sowing, viz., D1 (timely sown) and D2 (late sown) in the sub-sub plot with three replications. Among the different dates of sowing, irrigation scheduling and soil amendment application, of D1(timely sown), I1 (irrigation at 40% depletion from ASM), and S3 (vermicompost @ 5 t ha-1) showed the maximum yield attributes of wheat viz spike weight, number of spikelets per spike, number of grains per spike and test weight were observed during both years of the experiment (2020-21 and 2021-22), respectively. Timely sowing of wheat crop I1 (irrigation at 40% depletion from ASM), and S3 (vermicompost @ 5 t ha-1) showed the maximum yield observation, viz., grain yield, biological yield, and harvest index were observed during both years of the experiment (2020-21 and 2021-22), respectively. Thus, it can be concluded that a timely sown wheat crop, along with 40% depletion of available soil moisture and vermicompost @ 5 t ha-1 showed the best agronomic practices and resulted in the highest grain yield and economic return under sandy loam soil conditions at Himgiri Zee University.

Conclusion

From the above results, it can be concluded that irrigation applied at 40% DASM (Depletion from Available Soil Moisture) provided optimal conditions for wheat under timely sowing conditions. In addition to this, the application of vermicompost at a rate of 5 t ha-1 improved soil fertility by adding more nutrients to the soil, leading to better results compared to the other treatment combinations.
