Item Coconut - based cropping system keeps farmers cheerful(2014) Basavaraju, T.B.; Maheswarappa, H.P.; Nath, J.C.; Khandekhar, R.G.; Rajkumar, D.; Janakiram, T.Item Commercial flower crops in coconut garden under different agro-climatic conditions(2020-12) Maheswarappa, H.P.; Sumitha, S.; Rani, S.; Nath, J.C.; Basavaraju, T.B.; Shinde, V.V.Item Drip Irrigation Requirement of Coconut in Maidan Tract of Karnataka(2009) Basavaraju, T.B.; Hanumanthappa, M.The experiment on drip irrigation was conducted at Agricultural Research Station, Arsikere, Karnataka during 2000-05 in a 25 year-old coconut garden of local cultivar-Tiptur Tall. The quantity of water given through drip system was based on the 10 years average of mean monthly evaporation. Irrigation either through drip or basin system significantly increased the nut yield of coconut over rainfed control. Drip irrigation at 100 per cent Eo recorded significantly higher nut yield compared to drip irrigation @ 33 per cent Eo and 66 per cent Eo and was on par with basin irrigation at IW/CPE equal to 1.0 at 3 cm depth The rainfed control recorded significantly lower nut yield compared to treatments of providing drip or basin irrigation. The increase in nut yield in irrigation treatments over rainfed control was due to more number of functional leaves, production of more number of flowering bunches and female flowers. The leaf nutrient status was also increased with irrigation. The net returns and B : C ratio were highest with drip irrigation at 100 per cent Eo followed by basin irrigation and drip irrigation at 66 per cent Eo. Hence, drip irrigation at 100 per cent Eo is found suitable for coconut in the maidan tract of Karnataka. The water to be applied during summer months (February-May) is 65-75 litres/palm/day while for winter and rainy months (June-January) is 40-50 litres/palm/day.Item Effect of fertigation on the productivity of coconut(2014-08) Basavaraju, T.B.; Bhagya, H.P.; Prashanth, M.; Arulraj, S.; Maheswarappa, H.P.An experiment to study the effect of fertigation on the productivity of coconut was laid out at Horticulture Research Station, Arsikere, Karnataka during 2007-08 to 2011-12. Application of 25, 50, 75 and 100 per cent of recommended NPK through drip irrigation system was compared with the soil application of recommended NPK as well as control with no fertilizer application. Fertilizers were given through drip irrigation system throughout the year in ten equal splits at monthly interval excluding peak rainfall months of May and October. Application of 100 per cent NPK through drip irrigation recorded significantly higher number of female flowers and nut setting percentage compared to control and application of 25 per cent NPK through drip irrigation. The mean nut and copra yield per palm over five years was significantly higher with the application of 100 per cent NPK through drip irrigation compared to control and application of 25 and 50 per cent NPK through drip irrigation. However, the copra content was not significantly influenced by the fertigation treatments. Application of 75 per cent NPK through drip irrigation recorded nut and copra yield per palm on par with the application of 100 per cent NPK through drip irrigation and 100 per cent NPK through soil. The net returns and benefit-cost ratio in 75 per cent NPK through drip irrigation were also on par with the application of 100 per cent NPK through drip irrigation, but significantly higher than 100 per cent NPK through soil application.The study indicated the possibility of saving 25 per cent of the recommended fertilizers by adopting fertigation which ensures higher productivity in coconut.Item Effect of graded levels of NPK on the productivity of hybrid coconut in maidan tract of Karnataka(2010) Basavaraju, T.B.; Hanumanthappa, M.; Lavanya, T.N.Item Effect of integrated nutrient management practices on growth and yield of vegetable crops grown as intercrops in coconut (Cocos nucifera) garden(2016-10) Maheswarappa, H.P.; Naveen Kumar, K.S.; Basavaraju, T.B.Investigation was carried out at Horticulture Research and Extension Station, Arasikere, Karnataka, during kharif and summer seasons of 2012-14 to study the performance of different cropping sequences with vegetable crops and effect of integrated nutrient management practices on growth, and yield of vegetable crops under coconut (Cocos nucifera L.) based cropping system (CBCS). The experiment consisting of three cropping sequences of vegetable crops and four integrated nutrient management (INM) practices was carried out in FRBD with 5 replications. The study revealed that growth and yield of all the vegetable crops grown under coconut were significantly influenced by INM practices. Among the INM practices, pooled analysis of yield data indicated that, S3 treatment (5 tonnes FYM + 50% NPK + 25% N by vermicompost + 25 % N by composted coir pith (CCP)+ IIHR micronutrient spray) recorded significantly higher yield in okra (9.85 tonnes/ha), baby corn (4.55 tonnes/ha), gherkin (74.87 tonnes/ha) and cucumber (6.51 tonnes/ha) when grown as intercrop in coconut plantation.Item Etiology and management of coconut basal stem rot (Ganoderma wilt) in sandy soils of Karnataka(Indian Society for Plantation Crops, 2009-04) Palanna, K.B.; Ganesh Naik, R.; Basavaraju, T.B.; Boraiah, B.; Thyagaraj, N.E.Item Growth and yield performance of coconut hybrids in maidan tract of Karnataka(2011) Basavaraju, T.B.; Palanna, K.B.; Lavanya, T.N.; Prashanth, M.; Arulraj, S.Item Intercropping of medicinal and aromatic plants in coconut gardens(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.Item Performance of flower crops as intercrops in coconut garden in southern dry region of Karnataka(2018) Basavaraju, T.B.; Prashanth, M.; Maheswarappa, H.P.Item Potential coconut (Cocos nucifera) hybrids developed using Gangabondam (GBGD) as maternal parent for yield and quality for southern dry tract of Karnataka (India)(2020) Sumitha, S.; Maheswarappa, H.P.; Basavaraju, T.B.; Prashanth, M.; SwethaItem Potential coconut (Cocos nucifera) hybrids developed using Gangabondam (GBGD) as maternal parent for yield and quality for southern dry tract of Karnataka (India)(2020) Sumitha, S.; Maheswarappa, H.P.; Basavaraju, T.B.; Prashanth, M.; SwethaItem Productivity and economic benefits of coconut based vegetable cropping systems under central dry zone of Karnataka(2017) Naveen Kumar, K.S.; Maheswarappa, H.P.; Basavaraju, T.B.
