EFFECT OF PHOSPHORUS AND RHIZOBIUM INOCULATION ON YIELD AND YIELD COMPONENTS OF MUNGBEAN VARIETIES AND WEEDS BIOMASS
AbstractMicroorganisms play vital rolе in improving soil properties and enhancing agricultural productivity through nitrogen (N) fixation and phosphorus availability. A Field experiment was laid out at Agronomy Research Farm of The University of Agriculture, Peshawar, Pakistan during kharif 2016. Randomized complete block (RCB) design was used with split plot arrangement keeping three replications. Three varieties (NM-11, CHK-06 and Ramzan) inoculated with rhizobium strain were allotted to main plots while four phosphorus levels (0, 30, 60 and 90 kg ha-1) were designed as sub plots in the form of singlе supеr phosphate (SSP). Phosphorus (P) levels, rhizobium inoculation and varieties significantly (P0.05) affected the performance of mungbean. More days to flowering (48), pods formation (60) and physiological maturity (74) were recorded for Ramzan variety while less days to flowering (46), pod formation (56) and physiological maturity (68) with highest leaves plant-1 (24), branches plant-1 (15), plant height (70 cm), nodules plant-1 (15), pods plant-1 (19), biological yield (2756 kg ha-1), seed yield (842 kg ha-1), weeds fresh (55.7 kg ha-1) and dry weight (22.8 kg ha-1) was recorded for variety NM-11. Among phosphorus levels, more days to flowering (50), pod formation (62) and maturity (74) was recorded in control plot while less days to flowering (43), pod formation (57) and maturity (70) with highest leaves plant-1 (24), branches plant-1 (15), plant height (68.3 cm), nodules plant-1 (17), pods plant-1 (22), biological yield (3063 kg ha-1), seed yield (910 kg ha-1), weeds fresh (64.5 kg ha-1) and dry weight (25.4 kg ha-1) was recorded in plots which received P @ of 90 kg ha-1. Inoculated plots performed better for all the studied parameters than un-inoculated plots. It can be concluded from the experiment that inoculating Mungbean variety NM-11 with rhizobium (Phaseoli) along with P application @ of 90 kg ha-1 resulted in better yield and yield components.
