Crop details Selection of crop Origin and distribution Varieties Used
PROCCEDURE FOR PLANTATION OF CAPSICUM CROP Seed bed preparation manually prepared on dated 10 January 2011 Bed preparation for transplanting manually prepared with width 90cm and 1130 cm length and 20 cm height, of pathway 1 m was left along midway. Transplanting method on 23/01/2011. row spacing of 45 cm x 50 cm.
Crop period- total crop period of vegetable crop in the field for 4 months from transplanting. Irrigation – 5 day interval by can till the maturity of plant. Weed control- twice in week. Ventilation- 50 percent ventilation was provided in shadenet house fan pad cooling system was provided in polyhouse. Biometric characteristics- plant 'h' height, number of leaves and branches were measured at regular interval.
Measurement of Environmental parameters Temperature -with the help of digital thermohygrometer Relative humidity-with the help of digital thermohygrometer Light intensity-with the help of digital luxmeter. Yield -measured by electronic weight balance

CONCLUSIONS The average temperature inside the shadenet was about 3.41°C less than outside temperature, the average relative humidity inside shadenet was about 14.52% more than outside relative humidity and light intensity inside shadenet was about 47.96% of outside. The average temperature inside polyhouse was about 2.81°C less than the outside temperature, the average relative humidity inside polyhouse was about 12.58% more than outside relative humidity and light intensity inside polyhouse was about 44 % of outside. The plant was observed in shadenet 12.7 cm more than in polyhouse, no of leaves in shadenet 73 no. was more than in polyhouse and no. of branches in shadenet 6 no. was more than in polyhouse.
outcome The total yield inside the shadenet and polyhouse was 59 Kg & 48Kg respectively.
