Assessment of wheat through varietal investigation based on yield attributing traits in pyuthan, Nepal

A field experiment was conducted in Pyuthan, Nepal, from March to June 2024, to evaluate the performance of five wheat varieties (NL 1446, Sworgadwari, NL 1179, Khumal Shakti, and NL 1488) based on yield-attributing traits. The experiment followed a Randomized Complete Block Design (RCBD) with four replications. Data were collected on plant height, spike length, number of spike heads per square meter, number of grains per spike, grain weight per spike, thousand-grain weight (TGW), and total yield. Results revealed significant differences among the varieties. NL 1446 exhibited the highest yield (6.175 tons/ha) and superior performance in most yield-related traits, including plant height (104.05 cm), spike length (11.2 cm), and TGW (61.875 g). In contrast, Khumal Shakti had the shortest plant height (88.50 cm) and the lowest TGW (48.10 g). The number of grains per spike ranged from 36.70 (NL 1488) to 49.30 (Sworgadwari), while NL 1446 had the highest grain weight per spike (3.375 g). Sworgadwari and NL 1488 recorded the lowest yields of 3.650 and 3.550 tons/ha, respectively. The findings suggest that NL 1446 is the most promising variety for wheat production in Pyuthan due to its high yield and favorable agronomic traits, making it suitable for commercial cultivation.
