Item Coconut based high density multispecies cropping system in Assam(Indian Society for Plantation Crops, 2008) Nath, J.C.; Saud, B.K.; Chowdhury, D.; Deka, K.K.; Sarma, U.J.A field experiment was conducted from 1991 to 2001 to study the effect of different intercrops on yield and monetary benefits of main and intercrops at Horticultural Research Station, Kahikuchi under the All India Coordinated Research Project on Palms. The study was based on three coconut based cropping models i.e., Model-I: Coconut + black pepper + banana + Assam lemon + pineapple + ginger, Model-II: Coconut + betel vine + banana + Assam lemon + turmeric + colocasia and Model-III: Coconut alone (monocrop). The results revealed that the highest nut yield as well as per cent increase in nut yield was recorded in model-I followed by model-II and the lowest in model-III (monocrop). The soil fertility status in respect of pH, OC, N, P and K were also found to be higher in model-I than in model-II and model-III. Similarly, higher microbial population (Azotobacter) was also found in model-I as compared to the other models. The leaf nutrient status (N, P and K) of the main crop as well as the component crops in model-I showed sufficiency (above their critical levels) resulting in a direct influence on the nut yield and yield of intercrops. The model-I was found more profitable giving the highest net return of Rs.42,155/ha with a benefit cost ratio of 1.67.Item Intercropping of medicinal and aromatic crops in adult coconut garden under Brahmaputra valley region of Assam(2015-04) Nath, J.C.; Deka, K.K.; Saud, B.K.; Maheshwarappa, H.P.A field experiment conducted at Horticultural Research Station, Kahikuchi of Assam Agricultural University revealed the performance of medicinal and aromatic plants grown as intercrops in 32 year old Assam Green Tall coconut garden. There were three medicinal plants viz., sarpagandha (Rauvolfia serpentina), pipali (Piper longum) and vedailota (Paederia foetida) and two aromatic plants viz., citronella (Cymbopogon winterianus) and patchouli (Pogostemon cablin) in the experiment. The yield of all the medicinal and aromatic plants grown as intercrop in coconut garden were found to be reduced compared to their sole crop yields. The reduction in yield was less in patchouli (5.2%), followed by vedailota (7.0%), sarpagandha (8.9%), pipali (9.0%) and citronella (16.8%). The nut yield of coconut improved with intercropping with medicinal and aromatic crops. The piperine content in pipali, alkaloids in sarpagandha and essential oil content in patchouli were significantly reduced when grown as intercrops in coconut garden as compared to sole crop. However, the iridoid glycosides in vedailota and essential oil content in citronella were not significantly influenced by intercropping. Intercropping system of growing with patchouli under coconut recorded the highest net income (`178,089 ha-1) and B:C ratio (3.26) followed by sarpagandha (`157,484 ha-1 and 3.09), pipali (`113,118 ha-1 and 2.62), citronella (` 107,432 ha-1 and 2.40) and vedailota (`100,382 ha-1 and 2.36). Hence, intercropping of patchouli, sarpagandha and pipali with coconut can be recommended for Assam condition.Item Intercropping of medicinal and aromatic crops in adult coconut garden under Brahmaputra valley region of Assam(2015) Nath, J.C.; Deka, K.K.; Saud, B.K.; Maheswarappa, H.P.Item Kahikuchi Coconut Hybrid-1 A newly developed coconut hybrid for North East Region(2010-08) Nath, J.C.; Medhi, G.; Saud, B.K.; Deka, K.K.; Chowdhury, D.; Arulraj, S.Item Performance of coconut hybrid MYD × WCT in the Brahmaputra valley region of Assam(2017-06) Nath, J.C.; Deka, K.K.; Saud, B.K.; Maheswarappa, H.P.
