Chauhan, R. S.Parveen Kumar2016-10-212016-10-212015http://krishikosh.egranth.ac.in/handle/1/81201Vegetables are the main source of vitamins and minerals. The vegetables also offer better crop diversification and crop intensification. During winter season under north Indian conditions, it is extremely difficult to grow capsicum, cucumber in open field conditions; however various types of protected structures have been developed for growing some high value crops continuously by providing favorable environment condition and giving protection from the excessive cold and this is called polyhouse technology. The present study has made an attempt to have Economic analysis of vegetable cultivation under polyhouses in Haryana with these objectives. 1. To study the present status of polyhouse cultivation in Haryana. 2. To compare the economics of vegetable cultivation under polyhouse & open field conditions. 3. To identify the constraints and to assess the prospects of vegetable cultivation under polyhouses. The present study was conducted in Karnal district of Haryana selected purposely on the basis of maximum number of polyhouses in the state. Two blocks were selected randomly, i.e. Gharaundha and Indri. Again, two villages from each block were selected on the basis of predominance of vegetable cultivation both under polyhouses & open field conditions. Ten respondent farmers each under polyhouses & open field conditions were randomly selected from each village, thus making a total sample of 80 respondents. On the basis of the nature of the data, simple statistical tools like averages and percentage were used to compare, contrast and interpret results properly. The primary data for the agriculture year 2013-14 were collected by survey method by conducting personal interviews of the selected farmers with the help of specially designed schedule. The overall findings reveal that in polyhouses, farmers adopted three cropping pattern R1, R2 and R3 i.e. tomato-cucumber (R1), capsicum-cucumber (R2) and cucumber-cucumber-cucumber (R3) respectively. The cost of cultivation for R1, R2 and R3 were ₹607720.36, ₹581816.43 and ₹849876.2 per acre respectively. In comparative economics analysis the cost of cultivation of selected vegetables tomato, capsicum and cucumber under polyhouses were higher as compared to open field conditions by ₹206816.90, ₹246564.40 and ₹185651 per acre respectively. The net retunes from polyhouses were higher as compared to open field conditions by ₹51097.54, ₹124870.01 and ₹97138.68 per acre respectively. The results of the study revealed that the vegetables cultivation under polyhouses have contributed to the yield significantly. The major constraint reported by the respondent farmers were short life of polyethylene sheet, infestation of insect, nematodes & diseases, high cost of fertilizers and seeds. The constraints in the marketing of vegetable were lack of minimum support price, high price fluctuations, lack of market information and high cost of transportation.enCosts, Tillage equipment, Land resources, Crops, Productivity, Manpower, Vegetables, Cucumbers, Economics, PlantingThesis
