N2  - A pot culture study was conducted at the College of Agriculture, 
Vellayani to assess the effect of level of nitrogen, organic amendments and 
Azospirillum inoculation on the growth and productivity of vegetable chilli grown in 
pots under modified drip system of irrigation. The experiment was conducted with 
chilli cultivar 'Jwalamukhi' as test crop. The treatment included seven levels of 
nitrogen (No - 0.0, N1 –O4, N2 - 0.8, N3 - 1.6, N4 - 3.2, N5 – 6.4 and N6 - 12.8 g plant-1) 
three types of organic amendment application (O0 Control, O1 _ Vermicompost @ 
 200 g plant -1 , O2 _ Poultry manure @ 100 g plant -1) and 2 types of microbial 
inoculation (M0 _ No inoculation and M1 _ Azospirillum inoculation). Potting mixture 
preapred by mixing sand, soil and cowdung in 1: 1: 1 proportion by weight was used 
in the rooting medium. The medium was low in available nitrogen, medium in 
available phosphorus and low in available potassium. The irrigation was provided 
by modified drip system @ 1.5 litre of water plant-1 day-1. The experiment was laid 
out in completely randomised design with three replications. The results of the 
investigation are summarised below. 
Plant height, number of branches, DMP, canopy spread and 
RGR at different growth stages differed significantly with levels of nitrogen, 
application of different types of organic amendments and microbial inoculation. All 
these parameters were better under N6 level of nitrogen, application of poultry 
manure and with Azospirillum inoculation. Time of 50 percent flowering was 
minimised by N3 level of nitrogen, with poultry manure application and with 
Azospirillum inoculation. Other yield parameters like number of flowers plant", fruits 
plant-1, fruit girth and fruit length were better under N6 level of nitrogen, with poultry 
manure application and with Azospirillum inoculation. 
Maximum yield was obtained for Ns level of nitrogen, with 
poultry manure application and with Azospirillum inoculation. 
 
Uptake of N and P by plant was maximum at N6 level of 
nitrogen, with poultry manure application and with Azospirillum inoculation. . But in 
the case of K uptake it was maximum at N6 level, with vermicompost application and 
with Azospirillum inoculation. 
Profit pot-1 was maximum at N6 level of nitrogen, with poultry 
manure application and without microbial inoculation. 
The interaction between nitrogen, organic amendment and 
microbial inoculation N6O2M1 registered maximum value for plant height, number of 
branches plant", RGR (final stage, DMP, canopy spread, number of flowers plant-1, 
number of fruits plant-1, ascorbic content of fruit, chlorophyll content of leaf, N uptake 
and P20S uptake. In the case of 50 percent flowering N3O2M1 showed the minimum 
number of days. N6O1M1 recorded the maximum value for K2O uptake. NSO2Mo 
registered maximum profit pot-1. 
Practical utility of this experiment is, where little land is 
available and scarcity of water, vegetables can be profitably grown in pots with 
modified drip irrigation and under integrated nutrient management system.
