Abstract

A study was conducted to estimate the effect of potassium and KSB on the growth and yield of lentil at SKUAST-K during rabi 2019 and 2020. The experiment was laid out in randomized complete block design with eight treatments (Control, 10 kg K/ha, 20 kg K/ha, 30 kg K/ha, KSB, 10 kg K/ha + KSB, 20 kg K/ha + KSB and 30 kg K/ha + KSB) replicated thrice. Application of potassium alone or in combination with KSB had a significant effect on growth and yield of lentil. The combined application of 30 kg K/ha + KSB recorded highest the plant height (28.55 cm), pods per plant (49.93) and seeds per pod (1.87) but statistically at par with application of potassium at 30 kg/ha alone. The lowest value of growth and yield attributes was recorded in control treatment. The highest grain yield of 6.81 q/ha was observed with combined application of 30 kg K/ha + KSB which was at par with potassium application @ 30 kg/ha alone with the lowest yield recorded in control treatment. The experiment indicated that potassium application alone or in combination was found to have a significant impact on lentil growth and yield.

小扁豆对施钾和增钾菌的响应

研究了钾和KSB对2019和2020年水稻生长和产量的影响。试验采用随机完全区组设计，8个处理(对照、10 kg K/ha、20 kg K/ha、30 kg K/ha、KSB、10 kg K/ha + KSB、20 kg K/ha + KSB和30 kg K/ha + KSB)重复3次。单独施用钾或与KSB联合施用对小扁豆的生长和产量有显著影响。30 kg K/ha + KSB配施的株高(28.55 cm)、单株荚果(49.93)和每荚果种子(1.87)最高，但与单独施用30 kg/ha的结果相当。对照处理的生长和产量属性值最低。30 kg K/ha + KSB配施的最高产量为6.81 q/ha，与单独施钾30 kg/ha相当，而对照处理的产量最低。试验表明，单施或配施钾对小扁豆生长和产量有显著影响。
