Effect of Chicken Manure on the Growth and Uptake of N, P, and K by Spinach (Spinacia oleracea L.) Grown in Three Different Soils

Abstract

Chicken manure was applied at 0, 5, 10, 20, and 30 t.ha^-1 in pots containing 5Kg soil separately of three different soil series- Bijipur, Pahartali, and Mirsarai and spinach (Spinacia oleracea L.) was grown in them. The growth parameters and concentrations of N, P, and K in plant samples were determined. The pot experiment was carried out in the glass house of the Department of Soil Science, University of Chittagong. The soils were acidic in nature and low in CEC, organic matter, N, P, and K contents. The growth of spinach significantly increased with increasing rates of chicken manure application. The 30 t.ha^-1 chicken manure application produced the highest root and shoot dry matter yield. Nutrients such as N, P, and K concentrations in root and in shoot and their uptake by both parts increased significantly (p=0.01) with increasing rates of manure applications irrespective of soil types.
