ThesisItem Open Access Studies on induced mutations in rice (Oryza sativa L.)(Division of genetics and plant breeding ,Agricultural college and research institute , Coimbatore., 1971) Gopinathan Nair, V; KAUThesisItem 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 Studies on the burrowing nematode radopholus similis (cobb,1893) thorne 1949 on pepper(Piper nigrum L.) and its role in slow wilt disease(Department of plant pathology, University of agricultural sciences, Bangalore, 1976) Venkitesan, T S; Setty, K G HThesisItem 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 Studies on the performance of two groundnut varieties, TMV-2 and TMV-9, under graded doses of phosphorus and potassium.(Department of Agronomy, College of Agriculture, Vellayani, 1978) Purushothaman Nair, N; KAU; Sadanandan, NThesisItem Open Access Comparative studies on the fixation of nitrogen by certain common legumes(Division of Agronomy, Agricultural college & reseach institute Vellayani, Trivandrum, 1963) Rose, H L; KAU; Madhavan Nair, KThesisItem 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 Exploration of the feasibility of developing races of trichograma Australicum girault ( trichogramatidar, hymenoptera) suitable for different environments(Division of entomology ,Agricultural college and research institute ,Vellayani., 1970) Abraham, C C; KAU; Pradhan, S
