Effect of sowing methods and varieties on growth and yield of wheat (Triticum aestivum L.) in Dang, Nepal

Abstract

In this study conducted in Gadhawa Rural Municipality, Dang district, from November 2021 to April 2022, the impact of two sowing methods (Line sowing and broadcasting) and four varieties (Bijaya, Gautam, Aditya, and Borlaug 2020) on wheat was investigated. We aimed to identify the best sowing method and variety using a randomized complete block design with three replications. The study focused on various growth and yield parameters, including plant height, tiller number, grain per spike, effective tillers per square meter, thousand grain weight, grain yield per hectare, and biological yield per hectare. Line sowing was found to have the highest impact on biometrical as well as yield attributing characters. More height (111.51 cm), number of tillers (3.80), grain/spike (57.02), and grain yield (3.85 ton/ha) were obtained in line sowing. There was a significant difference observed among the varieties for all the traits except tiller number and biological yield. Borlaug 2020 was found to be superior for performance based on yield attributing traits which have grain/spike, effective tiller/m2, biological yield, and grain yield of 62.88, 177.15, 6.60 ton/ha, and 3.95 ton/ha respectively. From the interaction effects, variety Borlaug 2020 and line sowing method were found to be superior for cultivation. The study further demonstrates that farmers of Dang can combine Borlaug 2020 with line-sowing methods to obtain promising results.
