Abstract
The pot experiment was to assessing the nutrient balance and nutrient efficiency of green gram crop under various levels of LDPE incubation conducted in Instructional farm (North), Karunya Institute of Technology and Sciences, Coimbatore. The experiment was laid out in Complete Randomized Design (CRD) with nine treatments and three replications. The treatment in the nutrient studies shows negative response in control and in 0.5% concentration of LDPE and has positive response in the remaining treatments, in agronomic efficiency the higher concentration has negative response and Apparent recovery studies shows that nitrogen recovery was high in higher concentration, phosphorous and potassium recovery has negative results in lower concentration.
