    Dry matter production and accumulation in arrowroot (Maranta arundinacea L.) when intercropped with coconut
    (2007-02-08) Maheswarappa, H.P.; Nanjappa, H.V.
    A field experiment was conducted during the monsoon seasons of 1995-96 and 1996-97 to assess the effect of different agronomic practices on dry matter (DM) production and accumulation and yield of arrowroot (Maranta arundinacea L.) when grown as an intercrop in a coconut garden. Dry matter production, accumulation, and fresh rhizome yield did not differ significantly at 15-20 g or 25-30 g sizes. The total DM production per plant was significantly higher at 111000 ha1 but the fresh rhizome yield was on par at 166 000 ha1. Among organic manures, the total DM production was higher under farmyard manure (FYM) + NPK which resulted in higher fresh rhizome- yield. Vermicompost at both the levels also recorded significantly higher yield compared with FYM and composted coir pith applied alone, and NPK alone. Dry matter production and yield were significantly lower under the control treatment.

    Dry-matter production and accumulation in different parts of galangal (Kaempferia galanga) as influenced by agronomic practices when grown as an intercrop in coconut garden
    (2007-02-08) Maheswarappa, H.P.; Nanjappa, H.V.; Hegde, M.R.
    A field experiment was conducted to study the response of galangal (Kaempferia galanga L), grown as intercrop, to agronomic practices in coconut garden during 1995-98. The chlorophyll and carotenoid content did not differ significantly when mother rhizome and finger rhizome used as planting material. Plant population levels of 333,000 and 500,000/ha had the same effect with respect to chlorophyll and carotenoid contents. Organic manures like farmyard manure (FYM), vermicompost (VC) and combination of FYM + NPK and NPK applied alone had significantly higher chlorophyll and carotenoid content. The total dry-matter production increased significantly when mother rhizome, with 333,000/ha population, was used as planting material. Among organic manure treatments, FYM, VC and FYM+NPK significantly contributed to the increase in dry matter compared to composted coir pith (CCP) and NPK treatments. Fresh-rhizome yield was significantly superior with mother rhizome and with 500,000 population level. FYM + NPK combination recorded significantly higher fresh-rhizome yield. The harvest index improved significantly with mother rhizome treatment and at 333,000/ha population. Among organic manures, FYM, VC, FYM+NPK and NPK improved harvest indices compared to CCP and control treatments.

    (1999) Maheswarappa, H.P.; Nanjappa, H.V.; Hegde, M.R.
    A field experiment was conducted to study the effect of organic manures on certain physico-chemical and biological properties of soil and crop yield of arrowroot when grown as intercrop in coconut garden. Organic manures like. FYM and vermicompost (VC) application alone and FYM+NPK application decreased the bulk density, improved soil porosity and maximum water holding capacity (MWHC) to a greater extent, whereas composted coir pith (CCP) had its effect on these characters in lesser extent except MWHC. Organic carbon and pH of the soil was increased to a greater extent under FYM and VC treated plots compared to CCP. There was no change in above physico-chemical properties under NPK alone and control treatments. The microbial population and dehydrogenase activity was also higher under FYM and VC treatments compared to CCP treatments, whereas under NPK alone and control there was decrease in the microbial count and their activity. Among organic manures. FYM+NPK combination recorded significantly higher yield componments and fresh rhizome yield (17.1 t/ha) compared to FYM. VC. CCP and NPK applied alone.

    (2011) Basavaraju, T.B.; Nanjappa, H.V.; Umesha, K.; Vasundhara, M.; Arulraj, S.
    A field study was conducted at Horticulture Research Station, Arsikere, Karnataka during 2006-07 to 2008-09 to identify suitable medicinal and aromatic plants for intercropping in coconut gardens of maidan tract of Karnataka. The experiment consisted of 14 medicinal and aromatic crops viz., Kalmegh (Andrographis paniculata), Makoi (Solanum nigrum), Coleus (Coleus forskohlii), Garden rue (Ruta graveolens), Lepidium (Lepidium sativum), Tulsi (Ocimum sanctum), Arrow root (Maranta arundinaceae), Kacholam (Kaemferia galanga), Cowhage (Mucuna pruriens), Roselle (Hibiscus sabdariffa), Ambrette (Abelmoschus moschatus), Citronella (Cymbopogon winteranus), Lemon grass (Cymbopogon flexuosus) and Vetiver grass (Vetiveria zizanoides). The yield of all the medicinal and aromatic crops grown as intercrop in coconut garden were reduced compared to their sole crop yields. The reduction in yield was less in lemon grass (6.4 %), tulsi (23.5 %), arrow root (23.9 %), vetiver grass (25.1 %), kalmegh (25.7 %), makoi (29.1 %), citronella (30.2 %) and garden rue (30.5 %). The nut yield of coconut was improved with intercropping of medicinal and aromatic crops. The andrographolide content in kalmegh (4.40 to 3.20 %), rutin alkaloids in garden rue (1.68 to 1.40 %) and oil content in lepidium (19.60 to 17.23 %) were significantly reduced when grown as intercrops in coconut garden as compared to sole crop. However, the forskohlin content in coleus (0.43 to 0.61 %) and essential oil content in ambrette (0.24 to 0.29 %) were significantly increased by intercropping. In other medicinal and aromatic crops, the quality parameters were not significantly influenced by intercropping. The intercropping system of growing lemon grass under coconut recorded the highest net income (Rs. 91,561/ha) and B:C ratio (2.89) followed by garden rue (Rs. 81,865/ha and 2.79), tulsi (Rs. 77,472/ha and 2.71), kalmegh (Rs. 75,163/ha and 2.56), arrow root (Rs. 72,211/ha and 2.28) and makoi (Rs. 67,058/ha and 2.68). Hence, intercropping of lemon grass, garden rue, tulsi, kalmegh, arrow root and makoi with coconut can be recommended for maidan tract of Karnataka.
