Initial and final nutritional status of the soil was analysed and finally the economics of mixed cropping system was worked out. The yield of coconut grown with Morinda citrifolia seedling plants increased by 14.28% as compared to 9.6% in coconut grown with Morinda citrifolia tissue culture plants and 2.04% increase in monocrop coconut. Maximum yield of Morinda citrifolia (3001kg/ha) was recorded in seedling plants compared to tissue culture plants (2527kg/ha). Thus the study revealed that Morinda citrifolia as mixed crop increased productivity of coconut and the performance of seedling plants was better than tissue culture plants with B: C ratio of 1.86.Item Status of coconut basal stem rot disease in India – A review(2016-12) Snehalatharani, A.; Maheswarappa, H.P.; Devappa, V.; Malhotra, S.K.Basal stem rot is one of the important diseases of coconut accounting to severe yield loss in southern India. The disease in Indian subcontinent is reported to be caused by G. lucidum (Leys.) Karst., G. applanatum (Pers.) Pat. and G. boninense. Present status of the disease pertaining to occurrence and distribution in major coconut growing states, symptomology, etiology and epidemiology, disease indexing, pathogen diversity and its management methods are reviewed. The disease if unattended, is becoming a major threat to coconut production in Andhra Pradesh, Karnataka and Tamil Nadu states. Management of the disease is possible with continuous monitoring and implementing biocontrol based integrated management even though there is variation among the pathogenic virulence of Ganoderma isolates. As early disease escapes detection, recent developments in early detection, grouping and molecular identification of the pathogen and integrated disease management measures are summarized in this review paper.Item Studies on different formulations of the bioagent Trichoderma in the management of stem bleeding disease in coconut(2020) Neeraja, B.; Snehalatharani, A.; N.B.V.
