对两种主要粮食作物，即印度的稻米和小麦，在不同阶段的收获后损失进行了估计。对1982- 1983年至2001- 2002年期间所选粮食作物的面积、产量和生产率的时间序列数据进行了增长率分析。使用从卡纳塔克邦每种作物的100名农民、20名批发商、20名加工商和20名零售商收集的2003- 2004年调查数据，对收获后损失进行了估计。表格分析被用来估计不同阶段的收获后损失，函数分析被用来评估社会经济因素对农场一级收获后损失的影响。Shimoga研究区水稻产量的增加主要来自水稻种植面积的增加。在邦一级，水稻产量的增加是生产力和面积增加的结果，而在国家一级，这是生产力的提高。该国小麦产量的增加是由于小麦生产力的提高。农场一级的收获后损失估计为水稻3.82千克/克，小麦3.28千克/克。这两种作物在储存期间的损失最高。在农场一级对收获后损失有重大影响的因素已经查明，并强调了一些政策影响。
The post-harvest losses have been estimated at different stages in two major food grains, viz. rice and wheat in India. The time series data from 1982-83 to 2001-02 on area, production and productivity of the selected food grains have been subjected to growth rate analysis. The post-harvest losses have been estimated using the survey data collected from 100 farmers, 20 wholesalers, 20 processors and 20 retailers in each crop in Karnataka for the year 2003-04. Tabular analysis has been used to estimate the post-harvest losses at different stages, and functional analysis has been used to assess the influence of socio-economic factors on postharvest losses at the farm level. The increase in rice production in the study district of Shimoga has been mainly from increased area under rice. The increased rice output at the state level is the result of increased productivity and area, while at the national level it is the rise in productivity. The increased wheat output in the country has been due to increased wheat productivity. The postharvest losses at the farm level have been estimated to be 3.82 kg/ q for rice and 3.28 kg/q for wheat. The losses have been highest during storage in both the crops. The factors that influence the post-harvest losses significantly at the farm level have been identified and some policy implications have been highlighted.
