A Study on Nutrient Management for Potato Based Cropping Systems

Abstract

Nutrient availability is second only to water in determining crop yield over a given period and location. The function that a given nutrient plays in plant metabolic processes determines the extent to which that nutrient contributes to crop yield. Due to regional and temporal diversity in soil fertility, the current and generalised fertiliser recommendations made decades ago are becoming more irrelevant. In addition, the widespread depletion of macro and micro nutrients in the cultivated soil due to high crop removal and less addition of nutrients by farmers has led to the emergence of deficiency in soil and crops, resulting in a change in fertility from high to medium or medium to low nutrient status. Researchers investigate nutrient management for potato-based cropping systems in this work.
