Response of copper on growth and yield of tomato cv. pkm-1 in coastal soil
A Field experiment was conducted in a sandy loam soil to find out the effect of copper on the growth, yield and uptake of nutrients by tomato (Var. PKM-1). Ten treatments were applied. The result of the experiment revealed that soil application of CuSO4 @ 12.5 kg ha-1 and foliar spray 0.1% Cu (T4) enhanced the yield of tomato over control. The highest uptake of N and K was recorded in the treatment receiving soil application of CuSO4 @ 12.5 kg ha-1 along with foliar application of 0.2% Cu on 30 and 60 DAT (T8).
