N2  - A field experiment was conducted at the Instructional Farm 
attached to the College of Agriculture, Vellayani during 1999-2000 to 
study the combined effect of chemical fertilizers and organic manures 
on the productivity and quality of chilli, to assess the possibility of 
substitution of fertilizers by organic manures and also to work out the 
economics of production. The treatments consisted of combined 
application of chemical fertilizers and organic manures viz. poultry 
manure, vermicompost and neemcake in various ratios of 3: 1, 1: 1, 1:3 
and 0:2. The control treatment was POP recommendation of KAU (20 t 
ha! of FYM + 75:40:25 kg N, P205 and K20). The experiment was laid 
out in randomised block design. An abstract of the result is given below. 
Plant height, number of branches, shoot-root ratio and dry matter 
content differed significantly with various treatments. All these 
parameters were found to be increasing with increased level of chemical 
nitrogen. Shoot-root ratio was highest for vermicompost applied plots 
whereas the maximum value for all other growth parameters was produced 
by poultry manure treatments. 
All the yield parameters were significantly influenced by various 
treatments. Higher fruiting phase and fruit set was observed with

increasing chemical nitrogen level and maximum value was obtained 
for poultry manure treatment (3: 1). Poultry manure treatment (1: 1) 
gave good performance with respect to number of fruits per plant, 
harvesting interval and total yield. Higher levels of poultry manure 
along with chemical fertilizers also performed well. Length of fruit 
was highest for vermicompost treated plots along with chemical 
fertilizers (1: 1). 
Highest level of chemical fertilizer along with poultry manure 
gave good results with respect to LAI and dry matter production. RGR, 
CGR and NAR was highest for vermicompost applied plots. Keeping 
quality and ascorbic acid content was higher for poultry manure 
treatments. 
Regarding residual nutrients high soil K was registered by higher 
level of neemcake along with chemical fertilizer. Highest soil N was 
noted by highest dose of poultry manure (0:2). Poultry manure and 
chemical fertilizer in equal proportion obtained highest value for soil P. 
Highest dose of poultry manure together with chemical nitrogen gave 
good result for NPK content of plants. NPK uptake was also higher for 
poultry manure treatments. Incidence of bacterial wilt was least in dual 
application of chemical fertilizer and neemcake in the ratio 3: 1. 
The economics of cultivation revealed that poultry manure and 
chemical fertilizer application in equal proportion (1: 1) gave maximum 
net returns and benefit-cost ratio.
