The garbage dumps near human settlements of hunting and food gathering, emerged out as the nucleus of agriculture. Nearly ten Thousand years ago man learnt to grow the plants of his own choice from seeds & propagules as he saw them growing on garbage dumps. For present investigation Phaseolus mungo crop was taken. From stand point of determination of yield, sink parameters i.e. average number of pods per plant, average pod yield per plant, average length of pods, average number of seeds per pod, average weight of seeds per pod and grain yield gram / plot were calculated under different treatments. These experiments were laid in RBD with three replicates. From stand point of achieving maximum yield it is quite clear that weed free condition obtained through constant weeding is the best method.
