INFLUENCE OF NITROGEN AND PHOSPHORUS ON GROWTH AND YIELD OF CHILLI

Abstract

A field experiment was carried out during the period from November 2013 to May 2014 at Horticultural farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to investigate the influence of nitrogen and phosphorus on growth and yield of chilli. The two factorial experiment were laid out in Randomized Complete Block Design with three replications. Four levels of nitrogen N 0 : 0 kg N ha -1 , N 1 : 100 kg N ha -1 , N 2 : 120 kg N ha -1 : 140 kg N ha -1 and three levels of phosphorous P 0 : 0 kg P 2 O 5 ha -1 , P 1 , N 3 : 30 kg P , P 2 : 45 kg P 2 O 5 ha -1 and P 3 : 60 kg P 2 O 5 ha -1 were used in this experiment. Growth and yield contributing parameters significantly influenced by different doses of nitrogen and phosphorus fertilizers. The dose of N gave the highest plant height (cm) and most of the growth parameters increased with increasing nitrogen levels up to N 3 . The dose of P 2

gave the highest plant height (cm) and most of the growth parameters increased with increasing phosphorus levels up to P gave the highest plant canopy

3 . The treatment combination N (33.25 cm), fruit diameter (0.95 cm), fruit pedicel (2.87 cm), fruit length (5.60 cm), yield of fruits plant (235.00 g), average fruit yield plot -1 (3.39 kg), individual fruit weight (2.52 g) and average fruit yield (12.32 t ha -1 ). Based on the present results, it can be suggested that the combined use of 140 kg N ha -1 -1 with 60 kg P

increased plant growth and fruit yield of chilli.
