Abstract:
A field experiment was conducted in the experimental research farm of the School of Agricultural Sciences and Rural Development, Medziphema Campus, Nagaland University during the kharif season of 2016 and 2017 to study the impact of slope and intercropping of Soybean-Maize on soil fertility under different slopes in North East India. The experiment was laid out in strip plot design with three replications in which the slope was considered as main plot and intercropping as sub-plot. The data on soil quality indicators revealed that available N and available K showed significant variation due to addition of various treatments, whereas available P and organic carbon did not show any significant variation due to addition of treatments. Available N was found high with a value varied from 574.62 to 605.14 kg ha^-1, available P was recorded medium with a range from 10.02 to 13.18 kg ha^-1 while available K was found low with a value ranged from 73.4 to 99.28 kg ha^-1. The organic C in the soil was high with a value varied from 1.38 to 1.48%.
