Response of various varieties rate of NPK fertilizer on brinjal (Solanum melongena L.)

Nitrogen is an essential nutrients and vegetative growth of plant and levels as well as reproductive growth and yield. Therefore, the experimental design to response of brinjal various varieties rate of NPK fertilizer to the various levels (0, 50, 75 kg ha-1). The nitrogen is the successive summer seasons of 2016-17 year at the Sindh Agriculture University TandoJam, Pakistan. The all treatments randomized complete block design (Factorial) RCBD plot with three replication consider the nitrogen levels as the main treatments and brinjal cultivars (Black beauty and Black pearl) nitrogen levels showed the significant various growth are plant height (cm), number of branches plant-1, number of fruits plant-1, fruit length (cm), weight single fruit (g), weight fruits plant-1(g), fruit yield plot-1 (kg) and fruit yield (m tons) the marketable fruits yield (m tons). However, among the recorded fruits cultivars that the Black pearl with 150 kg ha-1 showed the better results regarding growth and better yield.
