Item Nutritional and health impact of substituting greengram by soya products in school lunch programme in Thrissur district(Department of Home Science, College of Horticulture,Vellanikkara, 2000) Latha Devi N; Usha VThe present study, entitled 'Nutritional and health impact of substituting green gram by soya products in school lunch programme in Thrissur district' was conducted among 150 school children, who were randomly selected, 50 each from three groups VIZ., soya supplemented lunch (SSL), existing school lunch (ESL) and no school lunch (NSL). The socio-economic details inferred through the survey were found to be satisfactory. Nuclear families with better housing facilities and good educational level wmthe striking features observed. Most of the fathers were casual labourers. Monthly income in most of the families was up to Rs.2000 in all groups. Most of the families owned their own houses. Food consumption survey revealed that all were habitual non- vegetarians. Cereals, other vegetables, fats and oils and sugar and jaggery were the most frequently used food items. Dietary profile of school children revealed that intake of all the food items, except green leafy vegetables met the daily requirement and all the nutrients except thiamine and riboflavin were above the RDA in all the groups. Majority of the mothers were having positive opinion about the school lunch programme. Most of the teachers opined that except for food materials, no other financial support for school lunch programme is obtained from the government. Evaluation of defatted soya products at different replacement levels with green gram showed that, soya grits at 20 per cent replacement level was the most acceptable combination in terms of organoleptic and nutritive qualities. Assessment of nutritional status after the study period revealed that, significant difference existed between the three groups with regard to body weight, height and MUAC, with SSL having more significant positive increment in body weight, height, weight/height' and MUAC. The most common nutritional deficiency disease observed among children was anaemia, which got reduced in SSL and ESL groups. Dental caries was observed in most ofthe children irrespective of the groups.Item Combining ability for shade tolerence and yield in greengram grown under coconuts(Department of Plant Breeding and Genetics, College of Agriculture, Vellayani, 2001) Preeta Liz Korah; Kamalam, NThe current research programme on "Combining ability for shade tolerance and yield in greengram (Vigna radiata (L.) Wilczek) grown under coconuts" was carried out at the Department of Plant Breeding and Genetics, College of Agriculture, Vellayani during 1998-2000. The objectives were estimation of gene action, combining ability effects of parents and hybrids and heterosis. The experimental material consisted of five lines, three testers and their fifteen hybrids. Analysis of variance revealed significant differences among the genotypes for all the eleven characters subjected to statistical analysis except height of plants and shade intensity. The genotypes L3 (MGG. 314), Ls (LGG. 460) and T3 (CO.2» were superior in mean performance for yield and most of the yield attributes. The hybrids Ls x T 2 (LGG. 460 x Pusa baisakhii and L1 x T3 (IIPRM.3 x CO.2) were superior in mean performance for yield, pod characters, photosynthetic efficiency and tolerance to pod bug infestation. Non-additive gene action predominated for all the nine characters showing significant differences among the treatments. Ls (LGG. 460) and T 2 (Pusa baisakhi) were the best general combiners for yield and 2 length of pod while L) (IIPRM.3) was the best combiner for crop duration, pods per plant and photosynthetic efficiency. The hybrid L) x T 3 (IIPRM. 3 x CO.2) was the best specific combiner for yield. Significant heterosis was observed for all the characters studied. Ls x T 2 (LGG. 460 x Pusa baisakhi) showed maximum relative heterosis and heterobeltiosis for yield and pod length whereas L) x T 3 (IIPRM.3 x CO.2) showed maximum heterosis over mid parent and better parent for days to 50 per cent flowering, days to final harvest, pods per plant and photosynthetic efficiency. Combining the mean performance, sca effects and heterosis, Ls x T 2 (LGG. 460 x Pusa baisakhi) and L) x T 3 (IIPRM.3 x CO.2) were identified as superior crosses in terms of yield and yield attributes. The hybrid L) x T 3 (IIPRM.3 x CO.2) was also superior for days to 50 per cent flowering, days to final harvest and photosynthetic efficiency.Item Intercropping tapioca (Manihot esculenta Crantz.) with pulses and groundnut(Department of Agronomy, College of Agriculture, Vellayani, 1978) Ramakrishna Bhat, H; Sadanandan, NAn experiment was conducted in the College of Agriculture, Vellayani during the year 1977-1978 to study the performance of tapioca intercropped with different legumes (Blackgram, cowpea, greengram and groundnut) applied with different fertilizer, half the recommended dose and full recommeded dose). The experiment was laid out in a randomised block design with three replications. The experiment was conducted under rainfed conditions. The results revealed that the growth as measured from height and number of leaves and yield of tapioca as adjudged by the various yield attributes was not depressed by growing the four legumes at the three levels of fertilizers. On the other hand the quality and size of tapioca tubers were improved due to legume intercropping. The dry matter content, starch content and the HCN content of tapioca tubers were increased significantly due to growing of legumes in association with tapioca.Item Standardization of hydroponics fodder production technology(Department of Agronomy, College of Agriculture, Vellayani, 2019) Sruthi Liz Thomas; Usha C Thomas
