The present investigation aimed to find out the “Effects of Basaland Foliar Application of Potassium in Indian Mustard (Brassica juncea L.) was carried out at Agronomy Research Farm of Faculty of Agriculture and Veterinary Science, Mewar University, Gangrar, Chittorgarh, Rajasthan. Geographically Chittorgarh. The experiment was laid out in Randomized Block Design. Replicated thrice with 09 treatment combinations, comprising like T1 Control, T2 40 kg K at basal, T3 20 kg K at basal followed by 20 kg top dressing at 25 DAS, T4 30 kg K at basal followed by 10 kg top dressing at 25 DAS. T5 2 Foliar applications of KNO3 at 25 DAS and 50 DAS, T6 20 kg K at basal followed by 1 foliar application of KNO3 at 25 DAS, T7 30 kg K at basal followed by 1 foliar application of KNO3 at 25 DAS, T8 20 kg K at basal followed by 1 foliar application of KNO3 at 50 DAS and T9 40 kg K at basal followed by 2 foliar applications of KNO3 at 25 DAS and 50 DAS.
The application of Potassium fertilizer on productivity was found most effective improve success on growth yield and nutrient uptake of mustard crops. The plant height was found to be maximum (8.74, 45.76 and 173.55 cm) at 20, 40 DAS and at harvest, The higher dry matter accumulation (1.36, 22.44 and 129.60) respectively, were recorded at 20, 40 DAS and at harvest, The maximum leaf area index (8.87), The highest seed yield (1645.00 kg/ha), The maximum biological yield (6174.92 kg/ha),The highest straw yield (4529.92 kg/ha), The higher potassium content (0.47 and 0.59%), The maximum potassium uptake (7.73 and 29.44 kg/ha), The highest net return (₹52250), The maximum B:C (1.74) in under treatment T9 (40 kg K at basal followed by 2 foliar applications of KNO3 at 25 DAS and 50 DAS, which was at par with T5 and T7). Whereas the minimum growth yield and nutrient uptake were recorded in T1 (Control).
