Abstract

The term “yield gap” refers to “the difference between actual yields and potential yield,”. The purpose of the study was to investigate the key factors limiting maize productivity in Karimnagar district of Telangana in order to develop strategies to reduce the yield gaps. So, for the present studymaize hybrid KNMH-131 was purposively. Purposive sampling technique was employed for collecting primary data from a sample of 30 progressive farmers and 30 normal farmers, so the total sample becomes 60 for the study. Thus, collected primary data was analysed with the help of yield gap analysis tables and production function analysis. The study revealed that the yield gap–I was observed to be -1.21 per cent and yield gap –II and yield gap-III were 3.97 and 23.13 per cent, respectively. Various yield gap indices in maize were worked out and the same are presented in Table 2. Various yield gap indices were worked out to know the untapped potential of maize in the farmers’ fields. The index of yield gap in maize was 21.92 per cent, the index of realized potential yield gap of normal farmers in maize was 78.07 per cent. The indices of realized potential farm yield presented in table indicated that the farmers, in general, were successful in exploiting the potential farm yield of normal farmers of maize to the extent of only 77.14 per cent. The analysis indicated the existence of a considerable percentage of untapped potential farm yields in maize.The production function analysis showed negative production elasticities for total labour (-0.083) and plant protection chemicals cost (-0.1499) which clearly indicates the excess usage of these inputs for progressive farmers. For the normal farmers plant protection chemicals cost and experience in farming resulted in negative results which indicates that the farmers need to know the current information on newly introduced pests and diseases and they have to take initiative measures for controlling the same.

Abstract

The village adoption programme (VAP) is to bring socio-economic development in villages by way of involving the village communities as a whole. The Regional Agricultural Research Station (RARS), Polasa, Jagtial adopted Avunoor village of Siricilla district. In view of bringing a change in agriculture activities were conducted i.e.diagnostic field visits, awareness programmes on impact of indiscriminate usage of pesticides, high yielding varieties etc.This study is helpful for documenting developmental activities carried out in the village, the changes occurred in production of crops and life style of the farmers and to make the village a model for other villages. The present study revealed that interventions carried out in adopted village resulted in agricultural developmental changes in village, i.e. yield levels increased upto 5 qntls / acre in paddy and cotton. Farmers shifted cultivation towards modern varieties i.e.JGL 18047, KNM 118 from traditional varieties. JGL 18047 area increased from 50 acres to 600 acres from 2015 to 2018 and KNM 118 was not cultivated in 2015 and now it was grown in 100 acres in 2018. Soil fertility increased by reduction of pesticides and fertilizers. Income levels were increased upto 1, 00,000 per year. Soil test recommendations are followed and application of organic manures to some extent.
