Growth and yield characteristics of chilli as affected by nitrogen in presence and absence of phosphorus and potassium

Abstract

An effect of nitrogen (N) in presence and absence of phosphorus (P) and potassium (K) on growth and yield characteristics of chilli {Capsicum annum L.) was studied at Coastal Agricultural Research Station, Southern Zone Agricultural Research Centre, PARC, Karachi, during 2008-2009. The crop under investigation was fertilized with a total of six treatments i.e. 90-0-0, 90-60-75, 0-60-75, 120-0-0, 120-90-105 and 0-90-105 kg/ha of NPK. The analyses of data revealed that it was possible to harvest a satisfactory crop yield without addition of P or K, but it would not be possible to get desired crop yields without application of N, because an adverse effect on fruit yield was noted in absence of N. On the other hand stoppage of P and K did not show any economically adverse effects. However, combined application of NPK positively enhanced growth and yield characters. It was concluded that N in presence of P and K (120-90-105 kg/ha) proved best for better production of chilli var. Malir local under agro climatic conditions of Malir district, Sindh.
