    Macronutrient status and yield stability of arecanut (Kahikuchi) under integrated nutrient management practice in Assam
    (2015-12) Paul, S.C.; Acharya, G.C.; Hussain, M.; Ray, A.K.; Sit, A.K.
    A long term field experiment was carried out in clay-loam soil at ICAR-CPCRI, Kahikuchi campus, Guwahati, Assam during 2000-2012 with arecanut variety Kahikuchi with seven nutrient combinations. The treatments included control (T1), 100 per cent vermicompost (T2), 200 per cent vermicompost (T3), 100 per cent chemical fertilizer (T4), 50 per cent vermicompost + 50 per cent chemical fertilizer (T5), 1/3rd vermicompost + 2/3rd chemical fertilizer (T6) and 2/3rd vermicompost + 1/3rd chemical fertilizer (T7). The treatment T7 produced highest fresh ripened arecanut yield of 16.7 kg i.e., about 3.6 kg dry chali per palm. Positive correlations were obtained between yield of arecanut and soil available N, P and K content. Significant and positive correlation was found between leaf N, P, K and available N, P and K content in surface and sub-surface soil. Available N, P and K content increased over the years under nutrient applied plot that reflected in yield of arecanut. The average yield in various treatments followed in the order of T7 > T5 = T6 > T2 = T3 > T4 > T1. The application of targeted, sufficient and balanced quantities of organic and inorganic fertilizer will be the need of the hour to make nutrients available for higher yield, soil fertility maintenance and agricultural sustainability without polluting environment.

    Recycling of organic biomass from arecanut based high density multi-species system models under Assam condition
    (Indian Society for Plantation Crops, 2008) Hussain, M.; Ray, A.K.; Maheswarappa, H.P.; Krishnakumar, V.; Ravi Bhat; Subramanian, P.; George V. Thomas
    Investigations were carried out during 2001 to 2004 to quantify the available biomass for recycling from the arecanut based high density multi-species cropping system models (arecanut, pepper, banana, clove, nutmeg, and citrus) under graded (full, 2/3rd,1/3rd of the recommended) level of fertilizers for all the crops. Results revealed that the total amount of available biomass from the system ranged from 8.76 to 10.50 t/ha/year. The highest amount of biomass for recycling was recorded from 2/3rd level of fertilizer dose (10.50 t/ha/year) under model I and the compost produced ranged from 5.4 to 8.4 t/ha/year and the highest was under 2/3rd level of fertilizer dose. The amount of nutrient contribution by recycling the compost in the garden ranged from 41.36 to 54.94 kg N, 32.69 to 42.55 kg P2O5 and 66.25 to 85.38 kg K2O per ha per year. The results also indicated that there was increasein the yield of main and component crops over the years. Yield of arecanut, citrus and pepper were higher at 2/3rd recommended level of fertilizer coupled with organic biomass recycling in the form of compost. However, banana yield was higher at full dose of recommended fertilizer.

    Sustainable productivity and economics of arecanut based high density multi-species cropping system under Brahmaputra valley region of Assam
    (2011) Hussain, M.; Ray, A.K.; Maheswarappa, H.P.; Subramanian, P.; Ravi Bhat; Krishnakumar, V.; Acharya, G.C.
    Field investigations were carried out on arecanut based high density multi-species cropping system at Central Plantation Crops Research Institute, Research Centre, Kahikuchi, Guwahati from 1998 to 2008 to find out productivity and economics of the system. Arecanut, banana, citrus and black pepper crops were tried in two models with full, 2/3rd and 1/3rd of recommended fertilizer levels along with recycling organic biomass in the form of compost. The results on yield of different crops indicated that there was increase in the yield of main crop and component crops over the years. Yield of arecanut, citrus, pepper were higher at 2/3rd of recommended level of fertilizer coupled with organic biomass recycling in the form of compost. Banana yield was higher at full dose of recommended fertilizer. The major share of the production cost was towards labour (55 to 65 %) followed by fertilizers (30 to 40 %). The employment generated in the system was 450-475 man days compared to 250-275 man days in arecanut monocrop. The net income and B:C ratio were higher under 2/3rd of recommended fertiliser level compared to full dose and 1/3rd of recommended level of fertiliser.
