The desirable early sowing of vegetable peanut by double film mulch could make fresh peanut pods available in market early and hence increase the benefits of peanut cultivation. Six sowing date were tested to investigate the effect of early sowing on the fresh pod yield, output value, profit and growth of peanut.
