Combined Effect of Organic Waste and Inorganic Fertilizers in The Environmental on major Nutrient Content and Uptake in Maize Groundnut Cropping Sequence

A field experiment was carried out under field conditions during both kharif and rabi seasons of 2019-2020 and 2020-2021 at Field No. 50B of Wetland Farm, S. V. Agricultural College, Tirupati campus (under the judicatory of Acharya N. G. Ranga Agricultural University). Nutrient content and uptake of major nutrients NPK during both the years of study (kharif 2019-2020 and rabi 2020-2021) on maize-groundnut cropping sequence was not significantly affected by the levels of NPK while significantly affected by the application of organic sources. The pooled analysis results also showed similar trend. However, interaction effect was nonsignificant between inorganic and organic sources during both the years.
