| dc.description.abstract | Field experiment was conducted during Kharif 2021 at ZAHRS, Brahmavar, Udupi to know the effect of soil application of potassium solubilizing bacteria and foliar application of potassium on soil properties and yield of paddy in coastal acid soils of Karnataka. The experiment was laid out in Randomized Complete Block Design with eleven treatments replicated thrice. The treatment comprised of recommended dose of fertilizer and absolute control for comparison along with supplemental addition of soil application of KSB (Bacillus mucilaginous) @ 5 kg ha-1 plus foliar application of 2 per cent KCl @ 30 and 60 DAT and 50 and 75 per cent recommended dose of K. Among the eleven treatments, the treatment received with recommended dose of N and P2O5 + 75 % K2O + soil application of KSB @ 5 kg per ha + 2 % KCl @ 30 and 60 DAT has significantly recorded higher growth and yield parameters i.e., plant height (102.10 cm), number of tillers hill-1 (22.90), number of leaves hill-1 (9.92), leaf area (310 cm2 hill-1), leaf area index (1.03), total dry matter production (84.61 g hill-1), number of productive tillers hill-1 (19.88), panicle length (22.71 cm), panicle weight (4.23 g), number of filled grains panicle-1 (119), total number of grains panicle-1 (129), test weight (26.14 g), grain yield (5436 Kg ha-1) and straw yield (7079 kg ha-1) as well as higher soil available nutrient status at harvest (N: 275.86 kg ha-1, P2O5: 65.76 kg ha-1, K2O: 129.10 kg ha-1, Zn: 2.63 mg kg-1 and Cu: 4.47 mg kg-1). Further, higher nutrient uptake and content of grain and straw of paddy (N: 63.87, 43.11 kg ha-1 and 1.175, 0.609 per cent, P: 20.10, 26.18 kg ha-1 and 0.370, 0.328 per cent and K: 57.31, 84.04 kg ha-1 and 1.054, 1.187 per cent respectively) and soil general microflora, potassium solubilizing bacteria, nutrient use efficiency and potassium determination and performance indicator also noticed in the above said treatment. | en_US |
