Experimental Study on Dynamic Root and Canopy Development of Peanuts under Different Water Regimes

Dynamic development of peanuts root and canopy under different water regimes was experimentally studied. The results showed that for peanut’s growth the flowering/needling stage was the period that was most sensitive to water status. Lack of water in this period would restrict root and canopy growth. The availability of water during this period also affected the dry-weight root to canopy ratio as well as their growth rate. The information is critical to further research on optimal root to canopy ratio and appropriate irrigation scheduling for peanut crops.
