They also do not prefer hot summer areas. An evenly distributed annual rainfall of 800 mm is suitable for it’s optimum growth and yield. Temperature above 38 °C results in sun burning of hulls & shriveled kernels and impacts the yields severely.

Soil Requirement for Walnut Farming:- Walnuts grow well in well-drained deep silt loamy or clay loamy soils which are rich in humus and supplemented with lime. The optimum soil pH of 6.0 to 7.5 would result in good yield. Make sure to supplement the soil with good zinc and boron.

Seedling trees: 12  x 12 m

Grafted on Juglans regia : 10  x 10 m

Grafted Juglans nigra:  8  x 8 m

Manures and Fertilizers in Walnut Farming:-  Add appropriate well rotten farm yard manure while preparing the soil. Use the following amounts of NPK for supplementing the soil. During first 5 years, apply small amounts of P & K (about 100 grams per plant). Thereafter, 45-80 kg/ha of P & 65-100 kg/ha of K should be applied. In regards to Nitrogen, a dose of 100 grams/tree should be applied in the first year and should increase 100 grams every year.

One can expect full commercial production after 18 to 20 years from planting time. However, grafted planting starts early fruit bearing (in 4 to 5 years after planting). In grafted plantation, full commercial production should start in 8 to 10 years.

Yield of Walnut Crop:- Fully grown walnut tree produces as high as 125 to 150 kg nuts. However, an average yield of 40 to 50 kg of nuts can be obtained per 1 walnut tree. Again, the yield depends on the cultivar and farm management practices.
