Effect of Postmethanated distillery Spentwash on the growth and yield of beetroot

Abstract

A field experiment was conducted at Amaravathy sugars, Udumelpet to study the effect of spentwash on beetroot crop. Results revealed that the treatment applied with spentwash (100% N through post methanated distillery spentwash) increased the yield of beetroot. Application of PMDSW favoured the yield attributes of Beetroot by enhancing the availability of nutrients. The maximum yield (10.80 t/ha) was obtained at T5 (PMDSW@ 288.33KL-1ha-1) and the minimum yield 7.5 t/ha) was obtained at T1 (Absolute control). The enormous quantities of plant nutrients present in spentwash offers an excellent opportunity to use it as a liquid fertilizer along with irrigation water, thus enabling the farmers to save cost incurred on fertilizers and at the same time achieve higher yields of crops.
