Influence on the nutrients of condiments irrigated by distillery spentwash in untreated and spentwash treated soil.

摘要

Cultivation of some condiments (Capsicum annuum, Allium sativum, Zingiber officinale and Curcuma domestica [Curcuma longa]) was made by irrigation with distillery spentwash of different proportions in India. The spent wash, i. e. primary treated spentwash (PTSW) and 33% spentwash, were analysed for their plant nutrients such as nitrogen, phosphorus, potassium and other physical and chemical parameters. Experimental soils, i. e. untreated (plot-1) and spentwash treated (plot-2) soils, were tested for their chemical and physical parameters. Condiment seeds/sets (Namadhari and Mayhco) were sown in the prepared land and irrigated with raw water (RW) and 33% spentwash. The influence of spentwash in the untreated and spentwash treated soils on the proximate principles (moisture, protein, fat, fiber, carbohydrate, energy, calcium, phosphorous, and iron), vitamin content (carotene and vitamin-c), minerals and trace elements (magnesium, sodium, potassium, copper, manganese, zinc, chromium and nickel) of condiments were investigated at their respective maturity. It was found that the nutrient content of all condiments was high in the 33% spentwash treatment than in raw water irrigation. Furthermore, the nutritive values were very high in spentwash treated (plot-2) soil irrigated with 33% spentwash than untreated (plot-1) and raw water irrigations.
