Abstract

At the University of Agriculture Peshawar, a field experiment was done to determine the best nitrogen dosage for brinjal (S. melongena) growth and yield response. The experiment was set up using a randomised complete block design (RCBD) with four replications, and there were six different urea treatments: 0, 275, 300, 325, 350, and 375 kg ha-1. The experimental soil had a sandy loam texture and had extremely poor fertility. The following parameters are measured: yield, fruit weight, fruit diameter, fruit length, number of fruit clusters plant-1, and number of flower clusters plant-1. The findings of the current investigation demonstrated that the greatest dose of urea applied had a beneficial, substantial impact on the development and reproductive characteristics of brinjal (S. melongena). Similar to this, urea application rates rose along with brinjal (S. melongena) yield and yield-contributing features. The application of 375 kg ha-1 urea produced the maximum yield (18.01 tonnes ha-1), whereas the control treatment produced the lowest yield (10 tonnes ha-1). Thus, according to the total study findings, the University of Agriculture, Peshawar's 375 kg ha-1 urea had the greatest performance. The study came to the conclusion that more research in various agro-ecological zones of Pakistan is required before a definite recommendation of the application dose can be made.
