This study analysed the resource use and technical efficiency of aggregatum onion production in peri-urban areas of Coimbatore city of Tamil Nadu. Cobb-Douglas production function was used to measure the resource use efficiency of the aggregatum onion production. Data Envelopment Analysis (DEA) was used to measure the technical efficiency of the farms. The results showed that the average yield of aggregatum onion was 10 tonnes per hectare with a coefficient of variation of 19 percent. The average net return was 81,175 with the B: C ratio of 1.48. The study on resource use efficiency revealed that the quantity of farmyard manure, phosphorus, and nitrogen had a positive and significant influence on aggregatum onion yield. The MVP ratio to MFC was greater than one for all the significant variables indicating the underutilization of resources, and there existed the possibility of enhancing their yield by increasing their use. The overall mean technical efficiency of aggregatum onion was 0.89, which indicated the possibility of increasing the yield of aggregatum onion by adopting better technology and cultivation practices.

Banana is the most important fruit crop in India which requires the various cultivation practices. For carrying out those cultivation practices various energies are required to meet sustainable production. The main aim of this study was to find out the resource use efficiency estimation for banana production in Erode District of Tamil Nadu. Primary data was collected from 100 sample farmers using well structured interview schedule. The empirical results shows that except human labour, nitrogen, phosphorus and diesel remaining all other variables included in the model were positive and human labour, machine labour, nitrogen, potassium, FYM, plant protection chemicals, irrigation water, sucker and electricity were significant among other variables. Subsequently, increase in 1% use of inputs such as machine labour, potassium, electricity, sucker and plant protection chemicals would increase the yield of banana 0.15 per cent, 0.20 per cent, 0.02 per cent, 0.01 per cent and 0.01 per cent respectively and 79 per cent of the variations in banana yield were influenced by the explanatory variables. Likewise price fluctuation plays a major constraint among the banana farmers. This study suggested the banana farmers to use more amount of potassium and to reduce the usage of human labour and as well as nitrogen fertilizer for sustainable use of resources.

The study analyses the economics of coconut production under organic farming in Coimbatore District of Tamil Nadu. Participatory Guarantee Scheme (PGS) was studied in accordance to how farmers get their organic farming certification under PKVY scheme in Tamil Nadu. The estimated variable cost was Rs. 43,025/ha. The total cost of cultivation was Rs.82,216/ha. The net income over operational cost was Rs.2,95,888/ha and net income over total cost was Rs.2,56,697/ha. Total yield was increasingly responsive with higher application of farm yard manure and bio- fertilizers. Results of scale efficiency shows majority of the farms were operating in optimum return to scale. Inadequate supply of labour and inadequate market for organic products poses as major constraints to organic coconut farming in the area of study. Aim: The purpose of the study was to find out the profitability level and responsiveness of yield with input application of organic farming through Participatory Guarantee Scheme (PGS) and how farmers actively involved in organic farming to conserve natural resources. Design of Study and Methodology: The study was conducted in Coimbatore district of Tamil Nadu (2020) with 60 sample respondents. Purposive sampling was adopted for the study and two blocks were selected based on the leading operator of PGS scheme. The data were collected through well-structured interview schedule which was prepared through pre-tested survey. The analytical methods followed in the study included cost and returns estimation, resource use efficiency and data envelopment analysis to reveal the exact scenario of organic farming practices. Findings of the study: The study showed about Organic coconut is found to be one of the most important and sustainable crop options. Estimates of Resource Use Efficiency show that coconut yield was relatively higher with use of farm yard manure and bio- fertilizers, compared to all other organic inputs Nearly, 32.5 per cent of the farms considered under study were found to be operating in constant returns to scale. The major marketing constraint faced by the sample farmers through organic farming was inadequate supply of labour and price fluctuations of coconut.
