Abstract

A polyhouse experiment at Sanjeevini Vatika, UAS, GKVK, Bengaluru (Rabi 2023–2024) evaluated planting density and nutrient regimes on broccoli hybrid nutrient uptake and soil dynamics. The experiment used a factorial randomized complete block design (RCBD). NS1250, under wider spacing with higher NPK application, showed increased nitrogen, phosphorus, and potassium uptake, while Lucky hybrid at closer spacing with lower inputs achieved superior nutrient use efficiency. Results indicate that strategic adjustment of planting and nutrient management under polyhouse conditions enhances both nutrient absorption and efficiency in broccoli, supporting greater sustainable production and soil health.
