VARIETAL EFFECT WITH DIFFERENT DOSES OF PHOSPHORUS FERTILIZER ON THE YIELD AND YIELD CONTRIBUTING CHARACTERS OF WINTER MUNGBEAN (Pages : 38 - 46)

The experiment was conducted to study the effect of variety with different level of phosphorus fertilizers on the growth parameters and seed yield of winter mungbean during November 2010 to March 2011 in the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh. Four varieties of mungbean viz. BINA Mung-1, BINA Mung-3, BARI Mung-4 and BARI Mung-5 and four levels of phosphorus viz. 0, 12, 25 and 35 kg P ha-1 were used in the experiment. The experiment was laid out in randomized complete block design (RCBD) with three replications. Results revealed that among the variety BARI Mung-5 the highest number of pods plant-1(20.45), mature pods plant-1 (14.97), pod length (5.49 cm), number of seeds pod-1 (17.78), seed weight plant-1 (29.49 g), 1000 seeds weight (40.68 g), straw yield (3.00 t ha-1), biological yield (4.34 t ha-1), harvest index (36.06%) and seed yield (1.34 t ha-1). Among the phosphorus level, the highest number of pods plant-1 (19.52), pod length (5.64 cm), number of seeds pod-1 (16.41), weight of 1000seeds (39.39 g), harvest index (35.94%), straw yield (2.99 t ha-1) and seed yield (1.32 t ha-1) were obtained from the application of 25 kg P ha-1. The interaction effect showed, BARI Mung-5 fertilized with 25kg P ha-1 gave highest result in all growth parameters and seed yield (1.34 t ha-1). It was observed that increase level of phosphorus fertilizer exhibited an increase in number of seed plant-1 and reached the maximum at 25kg P ha-1 and further increase of phosphorus did not increase the seed number plant-1. Further higher dose of phosphorus decreased the values of all yield contributing characters and seed yield. It is concluded that BARI Mung-5 fertilized with 25 kg P ha-1 gave the highest number of pods plant-1 (20.98), pod length (6.30 cm) and seed yield (1.44 t ha-1) compared with other treatments and it may be recommended.
