Abstract: Mustard (Brassica juncea L.) is an important oilseed crop cultivated worldwide. The present study was conducted to evaluate the effect of potassium and boron on the growth and yield of lentil. A field experiment was conducted using a randomized complete block design with three replications. The treatments included different combinations of Potassium levels (20 kg/ha, 30 kg/ha, and 40 kg/ha) and boron (1 kg/ha, 1.5 kg/ha and 2 kg/ha). The results indicated that the application of potassium and boron significantly influenced the growth and yield parameters of mustard. The combined application of Potassium at 40 kg/ha along with Boron 2 kg/ha (Treatment 9) significantly increased plant height, number of branches/plant, plant dry weight, number of siliqua/plant, number of seeds/siliqua, Test weight, seed yield and stover yield. These findings suggest that the integrated use of potassium and boron can enhance the growth and yield of mustard, thereby improving its productivity and economic returns for farmers. The result reported the application of Potassium at 40 kg/ha along with Boron 2 kg/ha (Treatment 9) recorded that the plant height (184.44 cm), branches/plant (14.80), dry weight (24.01 g/plant) and yield attributes siliquae/plant (125.75), Seeds/siliquae (15.13 g) Test weight (3.41), Seed yield (2135.15 kg/ha) and Stover yield (4043.38 kg/ha).
