INFLUENCE OF NITROGEN AND POTASSIUM LEVELS ON GROWTH AND YIELD OF CHILLIES (Capsicum annuum L.)
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 3
Abstract
The influence of nitrogen and potassium levels on chillies (Capsicum annuum L.) was evaluated at Dargai Malakand, Pakistan during the year 2010-11. Plants from nursery were transplanted on ridges in the field with recommended row to row and plant to plant spacing of 60 cm and 30 cm respectively. Different levels of nitrogen (0, 60, 120 and 180 kg ha-1) and potassium (0, 30, 40 and 50 kg ha-1) were investigated. Nitrogen levels showed significant effect on all growth and yield parameters. Nitrogen application at the rate of 180 kg ha-1 significantly affected plant height (68.3 cm), number of leaves plant-1 (294), number of branches plant-1 (18.3), stem thickness (2.43 cm), fruits plant-1 (59.4), fruit length (6.83 cm), seeds fruit-1 (152) and yield (8.803 tons ha-1). The maximum number of fruits plant- 1 (47.7), fruit length (5.76 cm), seeds fruit-1 (109) and higher yield (7.102 tons ha-1) were recorded with 50 kg K ha-1 which was statistically at par with 40 kg K ha-1 except for fruit length. Application of 180-40 kg N-K2O ha-1 are recommended for better growth and yield of chillies under the agro-climatic conditions of Dargai, Malakand Pakistan.
