Abstract:

An experiment was conducted at Sylhet Agricultural University, Bangladesh in 2017 to see the effect of lime and NPKS fertilizers on the growth and yield of Basella alba using acid soil. This pot experiment used six treatments viz. control, lime, NPKS, lime + NPKS, 75% NPKS and lime + 75% NPKS. The 30 kg amended (cowdung @ 5 t ha1) soils were filled into 46 cm2 earthen pots, and 3 healthy plants were used as test crop. The rate of urea-N, TSP-P, MoP-K, gypsum, and lime were 90, 18, 60, 15, and 3000 kg ha1 respectively. The lime, TSP-P, gypsum, and 1/3 of urea-N and 1⁄2 of MoP-K were applied as basal doses. The rest of the fertilizers were applied at 35 (1/3 of N and 1⁄2 of K) and 52 (1/3 of N) days after sowing (DAS). Randomized Complete Block Design with three replications used to arrange treatments in this study. The data were recorded at 35, 50, 65, and 80 DAS. The data was statistically analyzed using the R software for ANOVA, and means were compared with LSD values. Combined application of lime + NPKS responded significantly in almost all growth and yield parameters of B. alba. The highest and lowest yields were 809.34 and 468.27 g pot1 obtained from lime + NPKS and control, respectively. The treatments lime + 75% NPKS, NPKS and 75% NPKS showed the statistically identical result. Combined application of lime with fertilizers performed well due to the positive effect of lime with NPKS and reduction of soil acidity.
