Nutrient content and uptake by maize (Zea mays L.) crop due to application of distillery spentwash R O reject

Abstract

A field experiment was conducted during kharif 2013 to see the effect of this distillery spentwash R O reject application on nutrient content and uptake by maize (Zea mays L.) crop. The experiment consisted of seven treatments laid out in Randomized Complete Block Design with three replications. The experimental results indicated that the application of 150% N through distillery spentwash (DSW) R O reject significantly increased the nitrogen (1.48 and 0.69%), phosphorus (0.44 and 0.26%), potassium (0.63 and 1.97%) and other nutrient elements in both grain and stover, respectively compared to all other treatments. Significantly higher uptake of nitrogen, phosphorus, potassium (126.2, 40.5 and 192.3 kg ha-1, respectively) and other nutrient elements were recorded in treatment received 150% N through distillery spentwash (DSW) R O reject. Significantly lower values of nutrient content and uptake were recorded in treatment receiving RDF only. It is concluded that application of distillery spentwash (DSW) R O reject resulted in increased nutrient content and uptake of maize.
