To initiate farming install happa nets in sluice pit area and stock healthy finsh frys during first week of August after the NIRTHAL in Pokkali field. Formulated slow sinking (0.5mm) floating pellet feeds (1.2 mm) are ideal feed for the nursery rearing phase. Restock the nursery reared fishes to floating rectangular HDPE-PVC cages after 45 days. Five time feeding are ideal during nursery rearing phase and two time feeding are ideal in grow out phase.
- Farmer’s can feed Calf Milk Replacer as replacement of half of whole milk ration. This can to reduce the milk consumed by calves without affecting their health and growth rate. KVK recommends to adopt this technology in large farms.
- Soviet Chinchilla rabbits have showed improved litter size, less foot diseases, reduced kit mortality and 40% more weight gain in 5-6 month old kits.
- The leg disorders and egg deformities in case of layer poultry due to Calcium deficiency can be prevented by supplementary feeding of raw lime shell powder along with layer mash.
- Fruit rot disease in Nutmeg can be controlled by applying 40 Kg cow dung enriched with 4 kg neem cake and 500g Trichoderma applied in 2 split doses per plant per year in combination with pseudomonas 20g diluted in 1 litre sprayed over the canopy at monthly intervals.
- There is no difference between yield of vegetables grown in Flat planting beds and Grow bags whereas cost of flat planting bed is on higher side.
- Mini tillers are suitable for ploughing in those Pokkali paddy fields dried to such an extent that a man can walk over it. Pokkali fields can be dried in summer by pumping water out. The field capacity of mini tiller is 1.5 acre per day.
- Application of Verticilium leccanii 4 doses of 20g diluted in 1 litre of water can control banana rhizome mealy bugs. First application at the end of 3rd month of planting and subsequently at monthly intervals.
- Application of azospirillum in banana mixed with neem cake and FYM in 1:2:20 ratio at 3rd, 60th and 120th days of planting can reduce usage of chemical fertilizers by 25%. This reduces production cost.
- Application of PGPR mix I increase yield of vegetables. 62 per cent more production observed for Cowpea variety Anaswara. Application of PGPR Mix II reduces disease incidence in vegetables. Disease incidence reduced by 5 per cent in Cowpea variety Anaswara.
- Liming increases crop yield. Liming at the rate of 3.5 kg per one cent increased yield of Tapioca by 18 per cent.
- System of Rice Intensification (SRI) method of paddy cultivation increases yield while ensuring low production cost. The method resulted in 25-30% per cent increase in yield of paddy variety Uma. The cost of production reduced by 8-10%.
- Integrated crop management (ICM) in paddy increases yield by 25%. ICM included application of Lime, Neem cake, Azospirillum, Panchagavya, Fish amino acid, Trichoderma enriched vermicompost, Beauveria, Verticilium and Neem oil spray. Seed treatment with pseudomonas and as foliar spray, usage of Trichocards also included.
- Integrated pest, disease and nutrient management (IPDNM) can rejuvenate senile coconut palms. The IPDNM for coconut include regular crown cleaning, application of recommended dosage of chemical fertilizers in two splits, lime application, application of Trichoderma enriched cow dung, neem cake, Bordeaux mixture and Pseudomonas. The cost of this treatment per plant per year is 500. It takes 4 years to make the changes visible in treated palms.
- Integrated Pest Disease and Nutrient Management (IPDNM) of Nutmeg prevents fruit drop and fruit decay. It increases fruit set by 12 per cent and decreases fruit drop and fruit decay by 18-25%.
