Description
Summary:The study was carried out at Agriculture Research Institute, Jaffarabad at Usta Mohammed Balochistan. A wire house pot experiment was performed in Completely Randomized Design (CRD) with three replications. The aimed to assess efficacy of Zinc sulfate (ZnSO4.7H2O), as soil amendment on plant dry biomass, phyto availability and macronutrient uptake by two cotton genotypes (NIAB-78 and Bt-802) under in-situ condition. The top soil was treated with different concentration of Zinc (Zn) viz: Ck, 0.01, 0.02, 0.04, 0.08, and 0.16 mg L-1(w/v) hydrated ZnSO4-7H2O. The results indicated thatZn-0.04 mg L-1 application rate maximally increased the shoot dry biomass by 31.64% for NIAB-78 and35.82% for BT-802 respectively. Meanwhile, as compared to control the Zn concentration, uptake in shoot biomass and Zn utilization efficiency were increased with addition of amendment rates. However NPK concentration in shoot biomass was observed higher in NIAB-78 than BT-802 genotype. Such research should be focused on soil type, Zn-fractions and its mechanism under field condition and can improve soil fertility with essential plant nutrients and could be fruitful results in future sustainable agriculture for farmers community.
