INFLUENCE OF PHOSPHORUS AND POTASSIUM ON GROWTH AND YIELD OF MUNGBEAN (BARI Mung-6)

Abstract

The experiment was conducted at the research plot of the department of Soil science of Sher-e-Bangla Agricultural University, Dhaka during the period from February, 2014 to June, 2014 to study the influence of phosphorus and potassium on growth and yield of mungbean. The experiment was designed with three phosphorus level viz. P and three different potassium level viz. K 0 (0 kg P/ha), P 0 1 (15 kg P/ha), P (0 kg K/ha), K 1 2 (20 kg P/ha) (15 kg K/ha) and K (20 kg K/ha). The experiment was laid out in a two factors randomized complete block design (RCBD) with three replications. Results showed that different phosphorus and potassium levels significantly differed the growth and yield contributing characters of mungbean. The maximum seed yield (1.65 t ha (1.56 t ha (1.90 t ha 20 K kg ha -1 -1 -1 ) was recorded in 20 P kg ha ) was obtained from 20 K kg ha -1 treatments. The maximum seed yield -1 treatment. The highest seed yield ) was recorded with the treatment combination of 20 P kg ha -1 . On the other hand, the lowest seed yield (0.95 t ha -1 control treatment (no phosphorus and no potassium). The maximum N, P and K concentration in stover and soil was recorded in the 20 kg P/ha treatment. The -1 2 with ) was found in maximum N, P and K concentration in stover and soil was recorded in the 20 kg K/ha treatment. The highest N, P and K concentration in stover and soil was recorded in 20 kg P/ha with 20 kg K/ha treatment combination. Mungbean yield was increased with increasing the P and K levels.
