Abstract
The use of regular chemical fertilizers are known to increased crop yield, but also degrading soil quality (physically and chemically). Sugar industry wastes can be used as soil amendments to improve crop yield, soil physico-chemical characteristics and provide a reasonable economic means to recycle these wastes in an environmentally friendly manner. To the current research work achieve the aim, sugar industry bagasse ash was applied to Pisumsativum crop in pots having 2 kg soil at 10%, 20%, 30%, 40%, 60%, 80% and 100% respectively, compared to the control. The soil nature under the investigation was having a high pH (8.5), low in organic matter (8200 mg kg-1), and deficient in N (334 mg kg-1), P (4.4 mg kg-1), Zn (6.1 mg kg-1) and Fe (5.5 mg kg-1). Bagasse ash was rich in micronutrients like Fe, Mn, Zn and Cu and also contained sufficient amount of K and P. Consequently, total porosity of soil, available P, K, Fe, Mn, Zn and Cu content in soil, increased with the levels of bagasse ash application. On the other hand, dry bulk density declined which is a positive effect. ECe and pH of the soil was minutely increased. Yields and most of the yield components of Pisumsativum crop in pots, also increased due to bagasse ash application. It is recommended that application of bagasse ash 40-60% will result in enhanced yield of Pisumsativum crop soil.
