ArticleItem Open Access Effect of crop rotation on the population of Radopholus Similis Cobb. and yield of banana (Musa Aab cv. Nendran)(Kerala Agricultural University, 1995) Job S K Charles; Pradeep, K P; Gregory Zachariah; Premalatha, T; KAUThe population of burrowing nematode, Rado/iholns similis was reduced in a three year crop rotation involving banana-paddy-cowpea-paddy-elephant foot yam. The yield of banana crop in the second rotation cycle increased. In respect of output of banana the next best rotation was banana-tapioca-fallow sequence. Higher population build up of R. similis ami low yield of banana were observed after monocropping with banana.ArticleItem Open Access Effect of weed management on growth and yield of banana cv. nendran musa (Aab)(Kerala Agricultural University, 1995) Premalatha, T; Alice Kurian; Suma, B; Radhakrishnan, T C; KAUA field experiment was conducted to study the effect of weed management on growth anil yield of banana cv. Nendran and to identify the critical stages of weeding so as to get maximum returns. Reduction in growth parameters was observed in plots unweeded up to harvest and up to six months after planting compared to frequent monthly weeded plots. Conventional weeding and weeding up to late vegetative phase and bunch maturation phase resulted in more or less similar effect with respect to growth characters, duration and yield. Hence weeding during the first six months is critical for maximum growth and higher yield. Conventional weeding was found to he the most economical practice in banana.ThesisItem Open Access Studies on the fermentation and curing of cocoa beans(Department of Plantation Crops and Spices, College of Horticulture, Vellanikkara, 1983) Premalatha, T; KAU; Mohanakumaran, MInvestigations conducted at the College of Horticulture, Vellanikkara during 1979-81 indicated mini- basket lined with banana leaves and mini- box as the methods suitable for fermenting small quantities of beans . These methods were chosen from among the seven studied , based on the temperature development in the ferment and on the result s of the cut test. Polythene sheet was found to be a poor insulating material as compared to banana leaves having led to unsatisfactory aeration and low temperature build up during fermentation. Fermentation during the dry season was found to be better with respect to the fermentation characteristics and physical quality characteristics of the beans. Fermentation of beans from yellow /ripe pods and over-ripe pods gave higher proportion of commercially acceptable beans . The cured beans had desirable PH and good physical quality characteristics. Storing the harvested pods for two to six days before the extraction of beans for fermentation led to the development of optimum temperature in the ferment , desirable pH in the dried and the production of a higher proportion of commercially acceptable beans. Storing the cured beans increased the proportion of commercially acceptable beans . An increase in the pH of the beans was also observed during the 28-week storage.
