Abstract:
Rooftop cultivation along with greenhouse technology is now an attractive solution to overcome the problems of land shortage for agricultural production. Proper irrigation management and scheduling for crops grown on rooftops is only possible by knowing the crop coefficient (Kc) values of the crops which need to be estimated. An experiment was conducted at rooftop of the College of Agricultural Engineering and Technology, Odisha University of Agriculture and Technology (OUAT), Bhubaneswar to determine Kc values of green chilli crop for different crop stages. The values of Kc both inside and outside greenhouse were determined under four irrigation management levels i.e. with 10, 20, 30 and 40% of management allowable depletion (MAD) level. In addition, there was a control treatment to find out the values of Kc of green chilli. The findings of the study showed that the plant height and yield of green chilli inside the greenhouse was better as compared to the outside condition. The treatment with 10% MAD level performed best amongst all other treatments and gave maximum yield of 268.5 g/plant. The Kc values for green chilli inside the greenhouse for initial, development and mid-season stages are determined to be 0.33, 0.71 and 0.91, respectively whereas, for outside greenhouse scenario, these are 0.66, 0.92 and 1.12 for the three crop stages mentioned as above serially. These values of Kc can be used for estimation of crop water requirement and irrigation scheduling of green chilli to be grown under rooftop condition.
