Studying the Yield and Yield Parameters of Mungbean in Response to Different Weed-Crop Competition Periods

Impact of weed-crop competition periods on the yield and yield parameters of mungbean was investigated during the spring and summer season of 2018 at Agronomic Research Farm, Bahauddin Zakariya University, Multan. Treatments comprised of different weed-crop competition periods, weeds were allowed to compete for 15, 30, 45 and 60 days with mungbean after sowing. For comparison, weed free and weedy check plots were also maintained. Results revealed the importance of controlling weeds for getting better grain and other yield contributing traits during both the seasons. Uncontrolled weeds caused about 50 percent yield losses. Whereas similar results of grain yield and other yield related parameters were also recorded in weed free plots and weed-crop competition period for 15 days after sowing plots, while there is a gradual decline in yield and other yield related parameters if weed-crop competition periods were prolonged. These studies highlighted the importance of controlling weeds with further indication of controlling weeds till 15-30 days after sowing to get better yield of mungbean crop in both the spring and summer seasons.
