Item BORDEAUX MIXTURE - A UNIVERSAL BLEND FOR Phytophthora MANAGEMENT IN ARECANUT(2020) Thava Prakasa Pandian, R.; Shivaji Hausrao Thube; Chaithra, M.; Nagaraja, N.R.; Bhavishya; Ganesh N. Khadke; Jose, C.T.Item Enhancing soil fertility: comparative analysis of arecanut monocropping and intercropping with cocoa(2024-08-01) Ravi Bhat; Alpana Das; Bhabani Devi; Jayashree Dutta; L. S. Singh; Chaithra, M.Soil health is one of the important properties that decide the status of soil fertility. The main objective of the present study was to conduct a comparative analysis of soil health status between arecanut monocropping and intercropping with cocoa. We analysed and compared the soil pH, bulk density, moisture content, nutrient availability (N, P, K) and microbial diversity of the soil in arecanut+cocoa and arecanut monocrop systems at 0-30 cm and 30-60 cm soil depths. Our investigation revealed that the available macronutrient content reduced with depth in arecanut sole and intercropping with cocoa. At 0-30 cm soil depth, the available nitrogen (N), Phosphorus (P) and potassium (K) in intercropping system was 256 kg/ha,16 kg/ha and 117 kg/ha, respectively, whereas the nutrients were 202 kg/ha, 21 kg/ha and 125 kg/ha in monocropping system. The soil organic carbon (SOC) was high in the intercropping system (1.6%.) compared to monocropping (1.0%). Similarly, the HCl extractable micronutrient (Cu, Zn, Fe and Mn) content in the soil was higher in the arecanut intercropping system. The study revealed higher levels of SOC, available P, K, micronutrients, in the arecanut+cocoa system compared to arecanut monocropping. This suggests that adopting mixed cropping with cocoa can enhance soil fertility.Item Integrated Disease Management(2016) Chowdappa, P.; Thava Prakasa Pandian, R.; Chaithra, M.Item Morphological and Molecular Characterization of Endophytic Fungi Associated with Cocoa (Theobroma cacao L.) in India(2019) Chaithra, M.; Vanitha, S.; Ramanathan, A; Jegadeeshwari, V; Rajesh, V.; Vinayaka Hegde; Elain Apshara, S.Item Performance of local coconut (Cocos nucifera L.) germplasm under Assam conditions of the North East region of India(2026) Singh, L.S.; Niral, V.; Acharya, G.C.; Chaithra, M.; Alpana Das; Jyoti RoyThe study was carried out to elucidate the performance of local coconut accessions collected from different parts of Assam in the North East region of India, an experiment was conducted at the Research Centre, ICAR-Central Plantation Crops Research Institute. Observations were recorded on growth, yield, fruit and nut characters and tender nut water and quality of 13 local coconut accessions. The experiment was laid out in 3 replications, with 4 palms per replication. The study showed that accession, KKHC 4 produced the highest nut yield and kernel content, indicating its potential suitability for cultivation in the North East region. Accession KKHC 6 exhibited enhanced fruit size and a higher volume and quality of tender nut water, suggesting its value for both fresh consumption and beverage markets. These findings highlight the necessity for region specific coconut improvement programs and underscore the importance of selecting and promoting locally adapted germplasm.Item Phytophthora - A menace in monsoon to Cocoa (Theobroma cacao L)(2018) Thava Prakasa Pandian, R.; Shivaji Hausrao Thube; Chaithra, M.; Elain Apshara, S.Item Profiling Secondary Metabolites of Cocoa (Theobroma cacao L.) Endophytic Fungi Lasiodiplodia pseudotheobromae PAK-7 and Lasiodiplodia theobromae TN-R-3 and Their Antimicrobial Activities(2020) Chaithra, M.; Vanitha, S; Ramanathan, A; Jegadeeshwari, V; Rajesh, V.; Vinayaka Hegde; Elain Apshara, S.Item Screening methods to assess cocoa genotypes for resistance to black pod rot disease(2024) Chaithra, M.; Elain Apshara, S.
