Impact of distillery spentwash irrigation on the yields of some condiments: An investigation

摘要

Cultivation of three condiments, Garlic (Allium sativum), Ginger (Zinziber officinale) and Turmeric {Curcuma domestica) was done by distillery spentwash irrigation of three different concentrations. The spentwash treatments, primary treated spentwash (PTSW) diluted to 50% and 33% spentwash, were analyzed for their plant nutrients such as nitrogen, phosphorous, potassium and other physical and chemical parameters. Experimental soil was tested for its chemical and physical parameters. The seeds (sets) of the condiments (Namadhari and Mayhco) were sowed in the prepared land and irrigated with raw water (RW), 50% and 33% spentwash at the dosage of 5mm-10mm/cm~2 depending upon the climatic condition. The impact of spentwash on the yields of condiments at their maturity periods was investigated. It was noticed that the yields of all condiments were very high in 33% spentwash compared to 50% spentwash and raw water irrigation.
