Item Inter-regional comparision of farm labour productivity as revealed through the " Studies in the economics of farm management"(Faculty of the Post-Graduate School, Indian Agricultural Research Institute, New Delhi, 1965) Syamasundaran Nair, K N; Sirohi, A SItem Economics of production and marketing of vegetables in Ollukkara block in Thrissur district(Department of Agricultural Economics, College of Horticulture, Vellanikkara, 1992) Sandhya, V; Radhakrishnan, VThe present investigation on the production and marketing of vegetables (bittergourd and ashgourd) in Ollukkara block in Thrissur district was undertaken during the year 1990-91. The study aimed at estimating the cost of cultivation, cost of production, input-output ratio, resource use efficiency' and marketing efficiency of the two vegetables. The study also aimed at identifying the important marketing channels. Multistage random sampling was adopted for the study. Cost A1 , cost. A2, cost B1, cost B2, cost C1 and cost C2 per hectare were Rs .13,584.55, Rs. 13,914.53, Rs.13,954.23, Rs.15,958.24, Rs.20,563.37 and Rs.22,556.38 respectively for bitter gourd and Rs.6,630.22, Rs.6,910.22, Rs.7,012.22, Rs.8,689.80, Rs.9,360.07 and Rs.11,037.67 respectively for ashgourd. The largest single item of input was human labour for both bittergourd and ashgourd. The output of bittergourd was 13830 kg per hectare and 16509 kg per hectare for ashgourd. The gross value of output at the prevailing price was Rs. 42,364.63 for bittergourd and Rs.24,763.50 for ashgourd. Cost of production per quintal of bittergourd based on cost A1, cost A2 , cost B 1, cost B2 , cost C1 and cost C2 were Rs.98.00, Rs. 100.60, Rs.100.90, Rs.115.00, Rs.148.00 and Rs. 163.00 respectively. For ashgourd they were Rs.40.00, Rs.42.00, Rs.42.00, Rs.53.09, Rs. 56.00 and Rs. 66.00 in the same order Input-output ratios based on cost A1, cost A2 cost B1, cost B2 , cost C2 and cost C2 were 3.11, 3.04, 3.03, 2.65, 2.06 and 1.88 for bittergourd and 3.73, 3.58, 3.53, 2.84, 2.64 and 2.24 for ashgourd respectively. Bulkline cost per quintal for bittergourd was Rs.220 and Rs.85 for ashgourd. Farm business income for bittergourd and ashgourd were Rs.28,779.40 and Rs.18,133.28 respectively for the aggregate sample. Own farm business income for bittergourd and ashgourd were Rs.28,450.10 and Rs.17,853.28. Family labour income was Rs.26,406.40 for bittergourd and Rs.16,073.70 for ashgourd. Net income for bittergourd and ashgourd were Rs. 19,808.25 and Rs.13,725.83 respectively. Farm investment income was Rs.22,181.26 and Rs. 15,785.40 respectively for bittergourd and ashgourd.Item Economics of production and marketing of selected medicinal plants in Thrissur district(Department of Agricultural Economics, College of Horticulture, Vellanikkara, 1996) Mayadevi, A; Mukundan, KThe present investigation on the production and marketing of selected medicinal plants (Kacholam and Koduveli) in Thrissur district was undertaken during the year 1994-1995. The study aimed at estimating the cost of cultivation, cost of production, benefit-cost ratio, study the market structure and look into to the various uses to which these medicinal plants are put and the problems encountered in medicinal plants cultivation. Multi stage random sampling design was adopted for the study. The largest single item of input was human labour in Koduveli and seeds in Kacholam. Cost A1, Cost A2, Cost B1, Cost B2, Cost C1 and Cost C2 per hectare were Rs.26,678.09; Rs.26,678.09; Rs.27,534.09; Rs.27,534.09; Rs.52,534.09; Rs.31,549.59 and Rs.56,550.59 respectively for Koduveli and Rs.49,332.5; Rs.49,332.5; Rs.50,609.30; Rs.50,609.30 and Rs.75,609.30 respectively for Kacholam. The income measures in relation to different cost concepts in medicinal plants cultivation such as gross income, farm business income, family labour income, net income at Cost C1 and Cost C2 and were Rs.130400.69, Rs.81068.19, Rs.54791.39, Rs.79791.39 and Rs.54791.39 for Kacholam and Rs.136003.69, Rs.109325.6, Rs.83469.6, Rs.104454.1 and Rs.79452.8 respectively for Koduveli. Input-output ratio based on Cost A1, Cost A2, Cost B1, Cost B2, Cost C1 and Cost C2 were Rs.2.62, Rs.2.62, Rs.2.55, Rs.1.71, Rs.2.55 and Rs.1.71 for Kacholam and Rs.5.10, Rs.5.10, Rs.4.90, Rs.2.59, Rs.4.30 and Rs.2.40 for Koduveli respectively. The average per hectare yield in the district for Kacholam was 1862.9 kilogram (dried) and for Koduveli 6476.3 kilogram (green). Production function analysis done separately for the two medicinal plants revealed that area and seeds towards gross income were found to have positive effect on gross income. The sum of elasticities of production function for Kacholam (1.0862) and for Koduveli were (1.0228) respectively which indicated constant returns to scale. The major marketing channels identified in Thrissur market for marketing of medicinal plants was Producer-dealer-manufacturer. The producers’ net share on dealer rupee was Rs.69 per kilogram (92 per cent) for Kacholam and Rs.20 per kilogram (83.3 per cent) for Koduveli. The index of marketing efficiency was 11.5 for Kacholam and 7 for Koduveli. The analysis of marketing efficiency revealed that the efficiency of marketing of Kacholam was higher when compared to Koduveli. Non availability of good materials in sufficient quantities, unawareness of farmers about their cultivation, high post-harvest losses and unorganized trade are the main constraints encountered in medicinal plant cultivation.
