    Effect of landslope on uniformity of water distribution of sprinklers
    (Department of Land and Water Resources and Conservation Engineering, Kelappaji College of Agricultural Engineering and Technology,Thavanur, 1996) Jigimon T; Joby V Paul
    A study was conducted at Keleppaji College of Agricultural Engineering and Technology, Tavanur to find out the effect of land scope on sprinkler uniformity. A single nozzle sprinkler was used for the study. The study was carried out over an artificial platform. The water distribution pattern for three slopes viz; 12.5 %, 10.0 % and 7.5 % was studied for three riser positions viz; vertical, mid way and perpendicular to the land. Isohytes were drawn for the various positions in wind and no wind conditions for the three slopes. The uniformity coefficient, Cu values were evaluated and the spacing between the sprinklers for good overlap was found out. It is found that the water distribution is decreasing as the land slope is increasing. The perpendicular position was the ideal position for all the slopes. The optimum riser angles for various slopes are found to be 70 7 ‘30’ ‘for 12.5 % slope, 50 42 ‘38’ ‘for10.0 % slope and 40 17 ‘21’ ‘for 7.5 % slope with respect to the vertical position. The rpm of the sprinkler head for three riser positions was studied. In vertical position the rpm was almost same in all the slopes. It was decreasing as the riser position was changing from vertical to perpendicular in every slope. The rpm was less in wind conditions than in no wind conditions. The erosivity was also measured. The amount of soil collected for the various positions was evaluated. It was found that the amount of soil loss is increasing with the increase in land slope. It was maximum in vertical position, less in mid way position and least in perpendicular position for all the land slopes.

    Marketing Practices of The study entitled "Marketing Practices of Fruit and Vegetable Processing Industries in Thrissur District
    (Department of Rural Marketing Management, College of Cooperation Banking and Management,Mannuthy, 1996) Jeeja, T V; KAU; Rajan Nair, N
    The study entitled "Marketing Practices of Fruit and Vegetable Processing Industries in Thrissur District" was undertaken to examine the practices in procurement of inputs, selection of product mix and cost and to examine the marketing efficiency of the fruit and vegetable processing industries. Fruit and vegetable processing units, falling respectively in the classes of ‘oldest unit in the district', ‘excellent unit in the district’, ‘co-operative form of organisation’, and ‘a household rural unit’ were selected from the district. Farmers intermediaries in the procurement of raw materials, intermediates in the distribution network of processed products and consumers were selected randomly for gathering primary data. The data was collected during the period 1993-1995. Simple averages, percentages, tables, non-paramatric test and direct reporting comprised the methodology. The main raw materials used by the processing industry was fruits and vegetables collected from local production centres. However, raw materials were also procured from out-of-state production centres when insufficiency was felt and to improve the product range. The number of channels and intermediates in the procurement process was lengthy, but were performing certain critical functions at times. So the study suggests a revised model which combines the positive aspects of each channel and also provides satisfaction to the farmers, functionary and processing units. The product mix of the oldest unit was the highest while that of the rural household unit was the lowest. It was observed that when product mix was higher, price of products also went up. The marketing efficiency of the distribution network analysed through functional, price spread and consumer response analysis revealed that channel involving dealers was the most effective channel. Finally, a new model, from procurement of raw materials to distribution of procesed items, is suggested for improving the performance of processing industries.
