Effect of Sardar Amin Granules and Bentonite Sulfur on the Productivity of Maize-based Cropping System in a Sandy-loam Soil

Abstract

Maize among one of staple cereal accounting major proportion of human diet accounting 42% of worlds’ food calorie and 37% of protein intake. However, there is a need to optimize its nutrient content due to deficiencies in soil. The application of nutrient additives helps in supplementing the soil with these essential nutrients and ensures crops’ optimum growth. Purpose of this study is to evaluate the efficiency of Sardar amin granules (SAG) and bentonite sulfur in various proportions to improve nutrient uptake by sown crops. A three-year field experiment study (2018-21) was conducted on maize based cropping systems viz. Maize-wheat, Maize-potato-onion, and Maize-potato-summer moong at research farm, department of soil science, Punjab Agricultural University, Ludhiana. At the end of two-year field experiment, the results revealed numerical increase in yield of maize, wheat, onion and summer moong grown in rotation and products were recommended as additional fertilizers sources over the recommended dose of fertilizers considering the type of regional soil.
