Influence of Planting Dates on NPK Composition in Soybean Cultivars: A Comparative Analysis

Abstract

The present study explores the influence of planting dates on NPK composition in soybean cultivars, conducting a comparative analysis across various planting schedules. Legumes provide a protein-rich source of food which is an essential part of the diets of people inhabiting in the tropics.. Growth, development, and production of Soybean Glycine max (L.) are negatively impacted by delayed planting dates and poor environmental circumstances. The nitrogen, phosphorus and potassium accumulation at harvest and nitrogen, phosphorus and potassium content in seed impacted by changes in photoperiod, temperature, and precipitation with delayed planting. Extremely high temperatures and drought stress are examples of environmental variables that negatively impact plant development and productivity and are frequently linked to delayed planting. The finding reveals significant variation in the NPK composition contingent on planting dates, underscoring the importance of optimal timing for planting. This study also provides valuable insights for farmers and agronomists seeking to optimize soybean production through strategic planting schedules.
