Nano Urea and Plant Density Optimization for Enhanced Sweet Corn (Zea mays L. saccharata) Productivity: A Comprehensive Review

Sweet corn (Zea mays L. saccharata) is renowned for its high sugar content and nutritional value, making it a staple crop in many diets worldwide. Achieving optimal growth and yield in sweet corn requires efficient nutrient management and appropriate plant density. Nano urea, a novel fertilizer known for its controlled-release properties, promises enhanced nutrient delivery and utilization compared to traditional urea. This review synthesizes recent studies on the effects of nano urea and plant density on sweet corn growth, yield and yield attributes. The findings suggest that integrating nano urea with optimal plant density can significantly boost sweet corn productivity. Additionally, the review explores future research directions and implications for sustainable agricultural practices.
