RESPONSE OF MUNGBEAN TO VARIOUS LEVELS OF PLANTING DENSITY AND PHOSPHORUS

The present study was carried out to determine the response of mungbean to various levels of planting density and phosphorus. The experiment was laid out in randomized complete block design under split plot arrangement having three replications at the Research Area of University College of Agriculture, Sargodha, Punjab, Pakistan during the spring seasons of 2013. Planting density was assigned in the main plots (20 cm, 30 cm and 40 cm row spacing), whereas phosphorus rates (40, 80, and 120 kg ha-1) were applied in sub plots. The net plot size was 2.4 m x 6 m. Observations on various agro-physiological parameters of crop was recorded using standard procedures. Data analysis was performed by Fisher’s analysis of variance, and the means statistically different were separated by LSD at 5% probability level. Plant height at harvest and number of seed per pods were not significantly affected while number of pod bearing branches, numbers of pods per plant, 1000-grain weight, seed yield and total dry matter were affected significantly by the planting density. The highest seed yield (977.71 kg ha-1) was obtained at planting density when the crop was sown at a distance of 30 cm row spacing (333333 plant ha-1) and phosphorus was applied at the rate of 80 kg ha-1.
