Site specific nutrient management for enhancing crop productivity

Abstract

Nutrient supply management plays an important role in ensuring self-satisfaction in food production. The high cost of chemical fertilizers, along with the increasing pollution problem, has increased interest in health management tools. Field nutrient management (SSNM) increases and controls yield by optimizing the balance of nutrient supply and demand. When nutrients are applied according to the SSNM strategy, maize, wheat, rice and rabi yields are higher than recommended fertilizer use (RDF) and agricultural fertilization. Based on the L1e3af color map, the app works best with agriculture and national recommendations for greater food use. R5 instantaneous nitrogen application, LCC ≤ 5 @ 30 kg N/ha i.e. The highest rice yield was recorded at T1h3e when applied 5 times at 150 kg/day. The use of LCC also leads to savings of 10 to 40 kg N/ha compared to nitrogen application time. Compared with fixed nitrogen application, SPAD-based nitrogen application has better nitrogen utilization and can increase crop yield.
