![]() During the harvest season, leaf litter is removed to facilitate the picking of nuts. Although Cashew orchards are reported to produce 1.38 to 5.20 t ha-1 Cashew leaf litter biomass with reported composting efficiency of 65%, they have not been properly recycled in Cashew orchards. ![]() It has been reported that only 20% of the area under Cashew cultivation is nutritious. If Cashew is being grown as an organic plant, then nutrients are provided in the form of oil cake, green leaf compost, vermicompost, poultry manure, etc.įor deciding yield, determining soil fertility and nutrient supply is one of the key factors. It is recommended that young plants use well-decomposed farmyard manure or compost. Applying Cashew grafts after making pits and filling up with soil + organic matter such as farmyard manure, compost or cake is beneficial for strong growth and early growth in the early stages. Organic fertilizers are essential during the early stages, preferably when planting in pits. In case you miss this: Cashew Nut Farming Project Report, Cost and Profit Image Source Nutrition management under organic farming in Cashew Organic fertilizers Due to its extensive root system, Cashews can get large amounts of nutrients from the soil and small farmers rarely fertilize the crop. However, most current Cashew growers do not fertilize Cashews, except for Cashew corporations or Cashew-growing state forest departments that own Cashew orchards. ![]() Manure application in Cashews is not a regular practice in existing orchards in India, although the proper application of fertilizer may be the fastest way and a viable means of increasing Cashew productivity. Compost manure fertilizer for Cashew tree Fertilizers should be applied only after weeding and clearing individual tree basins within a radius of 2.5 meters to avoid competition for nutrients from weeds. Instead of applying fertilizer twice a year, the frequency can be limited to once a year, which is compatible with the “flushing and early flowering phase”, which can save some application costs. The trenches should be closed immediately after fertilization and it is better to apply green leaf mulch to increase the efficiency of fertilizer application by plants. In sloping soils in lateral soils and areas with heavy rainfall, fertilizer should be placed in round trenches 25 cm wide and 15 cm deep, which are 0.5 meters, 0.7 meters, 1.0 meters, and 1.5 meters away from the trunk in the first, second, third and fourth year after planting, respectively. Fertilizer is to be applied after the end of heavy rains and after weeding and clearing the roots of individual trees. The main reason for this is that the NPK’s recommended dose for Cashews is not available in any of the complex fertilizers currently available in the market. It is always advisable to use straight fertilizers instead of complex fertilizers for Cashew. In red loamy soils and low rainfed areas (east coast), fertilizer should be applied in round bands. ![]() In sandy and laterite soils, fertilizer should be applied in a circular trench in soils of sloppy land and areas with high rainfall. It should be done during the post-monsoon season (September-October) when there is adequate moisture in the soil. Fertilizers in Cashew should be applied after pre-monsoon (May-June) and post-monsoon (September-October) should be fed in two divided doses. Before applying fertilizers, make sure that the soil has adequate moisture. Though, the fertilizers should be applied in a circular trench along the drip line. Immediately after the cessation of heavy rains is the ideal time for fertilizer application in the Cashew crop. Image Source Ideal time for Cashew tree fertilizer application
