ThesisItem Open Access Effect of planting date, weight of rhizome and spacing on the growth, yield and quality constituents on turmeric (Curcuma longa L)(Department of Horticulture (Plantation Crops & Spices), College of Horticulture, Vellanikkara, 1983) Chatterjee, R K; KAU; Mohanakumaran, NThesisItem Open Access Genetic variability, path analysis and stability parameters in sesame(Department of Plant Breeding, College of Agriculture, Vellayani, 1985) Sverup, John; KAU; Gopinathan Nair, VBiometric analysis in a varietal collection of sesame was undertaken to study the genetic variability, correlations, path analysis and stability parameters. One hundred sesame types were evaluated in replicated trials at Vellayani in uplands during rabi and at Kayamkulam in rice fallows during summer. Genetic variability and correlations were estimated and path analysis worked out independently as both the locations. Location trials for estimating stability parameters were conducted at three places viz. in uplands during rabi at Pattambi and Vellayani and in rice fallows during summer at Kayamkulam. Large values for genotypic coefficients of variation were obtained for characters such as number of capsules on branches, number of capsules perplant, number of capsules on main stem and number of branches during rabi as well as summer. The lowest genotypic coefficient of variation was obtained for number of days to maturity during both rabi and summer. High values of heritability were recorded by seed protein content , seed oil content, height upto first capsule and weight of 1000 seeds under both conditions.ThesisItem Open Access Comparative micromorphologial and physico- chemical study of the upland and midupland laterite soils of Kerala(Department of soil science and agricultural chemistry, College of Agriculture, Vellayani, 1986) Sankarankutty Nair, R; KAU; Aiyer, R SThesisItem Open Access Evaluation of bhindi hybrids for yield and its components(Department of Plant Breeding, College of Agriculture, Vellayani, 1986) Sheela, M N; Manikantan, Nair, PThesisItem Open Access Influence of leaders in the development of rural areas(Department Of Agricultural Extension, College Of Agriculture, Vellayani, 1981) Shilaja, S; KAU; Tampi, A MThesisItem Open Access Production potential of two fodder grasses under different management practices(Department of Agronomy, College of Agriculture, Vellayani, 1986) Raghavan Pillai, G; KAU; Madhavan Nair, K PThesisItem Open Access Study of bacterial leaf spot of betel vine- biochemical changes and control(Department of Plant Pathology, College of Agriculture, Vellayani, 1986) Koshi, Abraham; KAU; James, MathewThe bacterial leaf spot is one of the most serious diseases of betel vine in Kerala. The bacterium is one of the most serious disease of betal vine. Confidering the seriouness of the disease , studies were undertaken on the different aspects of the disease and to find out a suitable control /management practice.ThesisItem Open Access Cytogenetic studies on intervarietal hybrids of sesamum (Sesamum indicum L.)(Department of Agricultural Botany, College of Agriculture Vellayani, Trivandrum., 1984) Chandramony, D; KAU; Krishnan Nair, NThesisItem Open Access Genetic studies on induced viable mutants in rice [Oryza sativa L.)(Department of Plant Breeding, College of Agriculture, Vellayani, 1985) Vijayagopal, P D; Gopinathan, Nair V
