Effect of calibration height on the performance of mobile application for the leaf area estimation

Abstract

Rice and wheat are the staple source of nourishment of billions of Indians. India is the second largest producer of rice and wheat after China, indicating the role of both the crop in food security of the nation. Both the crops played key role in transforming the nation from a food deficient nation to a food sufficient nation. The present study examines the growth and instability in in wheat area, production and productivity these two eminent crops over a period of 1950-51 to 2015-16 and also the study tries to decompose the major factors contributing to growth of production in India. The study revealed that throughout the whole period, there is positive significant growth rate in area, production and yield. The analysis over the sub periods showed variations in rate of growth. The analysis of instability showed that in both rice and wheat production recorded more variation as compared to area and productivity. Decomposition analysis showed that yield effect contributed more to rice production, whereas in wheat interaction effect was more dominant factor.
