• Developed Sustainable cropping systems for coconut, arecanut and oil palm based plantations

• Established successful coconut based cropping system models with horticultural crops such as medicinal and aromatic plants, vegetables, fruit crops, and spices as inter/mixed crops in coconut garden..

• Coconut based high density multispecies cropping system (HDMSCS) with black pepper, clove, banana, pineapple, vegetables, turmeric and ginger has been developed.

• Established arecanut based cropping system models with vegetables and flower crops. Developed Coconut based integrated mixed farming systems for sustainable profitability

• Evaluated Intercropping of fodder crops in coconut and integration with black pepper trailed on coconut, animal (dairy, rabbitry), poultry, fishery, mulberry cultivation and sericulture, Azolla as a supplementary feed for dairy animals for a decade and its sustainability and socio-economic viability was established indicating its advantage compared with coconut monocrop.

• Drip irrigation and water conservation regimen for coconut and arecanut

• Drip irrigation requirement along with mulching (with coconut leaves) has been standardized for coconut growing in littoral sandy soil,

• In laterite soil also water requirement through drip irrigation for WCT and DXT coconut cultivars has been standardized.

• Integrated approach for managing root (wilt) affected coconut garden

• Standardized agronomic management practices for increasing the productivity and profitability of root (wilt) affected coconut gardens through adoption of INM, recycling of available plantation biomass, efficient water management, In situ green manuring in the basins and inter/mixed cropping system with banana, pineapple, nutmeg, black pepper and tuber crops.

• Developed INM and organic nutrient management technologies for palms and palm based cropping systems

• Technology developed for successful utilization of composted coir pith in combination with inorganic fertilizer for coconut and arecanut (composted coir pith 50% + NPK 50%). Vermicompost from coconut leaves as organic supplements for coconut production (50% Vermicompost + 50% NPK) resulted in higher nut yield, and improvement in soil properties.

• Successfully established the use of coir pith as bedding material in deep litter system without affecting poultry birds and use of such enriched coir pith with poultry droppings as organic manure in coconut plantations.

• Standardised technology for In situ green manuring of cowpea (Vigna unguiculata) and its contribution towards soil nutrition in coconut root (wilt) affected gardens and coconut based HDMSCS.

• Glyricidia as green manure crop in coconut garden has been established.

• Impact of INM and organic nutrient management practices in coconut based high density multispecies cropping system (HDMSCS) with black pepper, clove, banana, pineapple, vegetables, turmeric, ginger and other annuals resulted in higher productivity of coconut through INM and organic nutrient management.

• Integrated nutrient management package (2/3rd of recommended NPK and recycling biomass in the form of vermicompost) for arecanut based high density multispecies cropping system with lemon, black pepper, banana for North Eastern region has been developed.

• Developed Location specific varieties/hybrids and crop management technologies for coconut,oil palm and palmyrah

Coconut:

• Four high yielding hybrids were developed and the proposals are recommended for notification by Central Variety Release Committee as detailed below.

• Kalpa Sreshta hybrid recommended for Karnataka and Kerala, Vasista Ganga recommended for Andhra Pradesh and Karnataka, Kalpa Ganga hybrid recommended for Karnataka, VHC 4 recommended for TN

• Two Dwarf varieties viz., Kalpa Jyothi and Kalpa Surya recommended for tendernut purpose and the proposals have been recommended for notification by Central Variety Release Committee.

• Water requirement through drip irrigation was standardised for different agro-climatic regions for sustaining higher productivity.

• Drip-fertigation suitable for different coconut growing regions was standardized which resulted in higher fertilizer use efficiency with a saving of upto 25% to 50% of recommended fertilizers.

• Location specific coconut based cropping systems have been established at different coconut growing region as of the country aiming for enhanced returns and system productivity.

• Location specific integrated technologies for managing insect pests and diseases of coconut have been standardized for different regions.

Oil palm:

• Water requirement through drip irrigation was standardised for different agro-climatic regions for sustaining higher productivity.

• Ten drought tolerant African Dura type oil palm genotypes viz., ZS 1, 2, 3, 5, 6, and 8, TS 2, 5, 10 and 11 were identified for further breeding programme

• Fertilizer schedule for Oil palm in different agro climatic regions has been standardised.

• Standardized fertigation requirement of Oil palm in different agro climatic regions.

• Location specific intercropping systems have been established at different oil palm growing regions for enhanced returns.

• 3 tenerahybrids of oil palm have been recommended for release:

• NRCOP 17: Have the yield potential of 27.2 t/ha and recommended for TN.

• NRCOP 4: Have the yield potential of 26.8 t/ha and recommended for A.P.

• NRCOP 2: Have the yield potential of 22.4 t/ha and recommended for Konkan region

Palmyrah:

• 247 accessions have so far been collected from different parts of India and are being maintained at Killikulam (TN) and Pandirimamidi (AP) centres for further evaluation.

• Inflorescence sap extraction process has been standardised for higher yield.

• Palmyrah jaggery prepared from inflorescence sap collected by adopting CPCRI method having a shelf life of six months under room temperature recommended for commercial release.

• Composting of Palmyrah leaf base pith with the following technology resulted in production of suitable organic manure in 100 to 105 days period with sufficient nutrient content. Palmyrah pith (100 kg) + Poultry manure (10 kg) + Urea (1kg) + Pleurotus fungus 2 bottles (1kg)+ Ligno Cellulolytic Fungi (1kg) + Trichoderma viride (1 kg) (turning for 15 days interval up to 45 days. Application of Trichoderma viride on 46th day and again turning at 15 days interval).
