Effectiveness of the use of biologically active substances (bas) at different levels of mineral nutrition of beans (paseolus vulgaris l.) grown under condition Afghanistan

Abstract

This experiment was carried out in experimental field of Alberoni University of Kapisa province of Afghanistan, in the summer of 2022 and 2023. The experiment was carried out in the form of randomized complete block design with three replications. The treatment included three different levels nitrogen (N30, N45, N60), phosphorus (P20, P40, P60), potassium (K10, K20, K30), and one level of gibberellic acid GA3 (G1 = 100ppm). This study flowing the weight of 1000-grain, Grain yield, biological yield and straw yield were affected by experimental treatments. In evaluating the effects, the highest rate of studies traits was obtained at yield parameters in bean. Moreover, due to the application of 100ppm gibberellic acid with N60, P60, K30 kg/ha the highest rate was obtained from weight of 1000 grain, Grain yield and biological yield, but in the parameter of straw yield was earned low amount then T4 during 2022 and 2023 year. In addition, investigating the effect of gibberellic acid showed that the highest rate of grain yield was obtained at T7.
