Comparative evaluation of two Canola germplasm under varying levels of NPK fertilizer in Layyah irrigated zones

Canola (Brassica napus L.) is a vital oilseed crop globally, renowned for its high nutritional and oil content. This study aims to assess and compare the growth and yield performance of two canola germplasm, namely Punjab and Faisal, under various NPK fertilizer levels in irrigated zones. The experiment employed a factorial experiment based on a completely randomized design with eight treatments, three replications conducted twice in 2021 and 2022 at Chak no. 114 Shahpur Daurata, situated at latitude 30.9693° N and longitude 70.9428° E. The findings indicate that the optimal fertilizer rate for canola cultivation in Pakistan is dependent on the variety and level of NPK fertilizer. The recommended NPK fertilizer enhanced the plant height, number of leaves, pods, 1000-grain weight and yield of canola significantly. In terms of yield and growth parameters, the Punjab canola variety outperformed the Faisal canola variety. The highest yield was achieved in T1 treatment that received the recommended NPK dose of (100:75:30 kg/ha1 ). This study's outcomes are critical for sustainable agricultural intensification, which is essential to meet the growing population's food demand. This comparative evaluation of two canola germplasm under varying levels of NPK fertilizer in irrigated zones is a crucial research domain that can provide essential insights into optimal fertilizer management practices for canola cultivation in Pakistan. Therefore, the application of recommended NPK doses in conjunction with the Punjab canola variety may result in increased crop yields for local farmers, specifically under the prevailing soil and climate conditions in Shahpur Durata
