Abstract
A field experiment was conducted at the experimental station of the Institute of Agricultural sciences, University of the
Punjab Lahore, to assess the impact of natural and chemical fertilizers on development and yield attributes of a local
germplasm of chili (Capsicum annuum L.) in the kharif season of 2019 using Randomized Complete Block Design
(RCBD) with five replications. There were seven treatments with various sources and levels of natural and inorganic
supplements and treatments i.e. T1 (control), T2 (1kg farm yard manure), T3 (250g humic acid), T4 (800g compost),
T5 (RD) recommended dose i.e. 440g, 270g, 160g NPK50% + 1kg FYM), T6 (440g, 270g, 160g NPK50% + 800g
compost), and T7 (440g, 270g, 160g NPK50% + 250g humic acid). Plant height, number of leaves, number of primary
branches, average leaf area, total yield, total chlorophyll content and total carotenoid content was estimated. Amongst
the different treatments, the T7 (440g, 270g, 160g NPK50% + 250g humic acid) was recorded as the best treatment in
terms of plant height, number of leaves, total chlorophyll content, total carotenoid content and T5 (440g, 270g, 160g
NPK50% + 1kg FYM) was found to be the second-best treatment in terms of number of primary branches, average leaf
area and yield. The study provides the information to the other researchers for the germplasm enhancement, desirable
traits and high yield potential of the chili.
