NOVELTY - Method for planting four-season mulberry fruit involves forming a groove, and applying base fertilizer containing silkworm droppings, and xanthan gum, performing treatment of plant before planting, planting treated plants, applying urea fertilizer to plants, pruning mulberry branches, applying fertilizer during flowering period (end of March to early April) to enable rapid expansion of young fruit, and controlling pest and disease damage by spraying carbendazim WP on branches.    USE - The method is useful for planting four-season mulberry fruit (claimed).    ADVANTAGE - The method reduces application amount of inorganic fertilizers, and damage to environment, is cost-effective, and improves quality of fruits that has sour and sweet, taste.    DETAILED DESCRIPTION - Method for planting four-season mulberry fruit involves (a) forming a groove having depth of 45 cm, and width of 55 cm in selected land, and applying base fertilizer comprising 140-170 kg/mu silkworm droppings, 10-20 kg/mu xanthan gum, 40-80 kg/mu weathered coal, 30-50 kg/mu coarse sand, 30-40 kg/mu wool powder, 20-30 kg/mu podzolic soil, 40-60 kg/mu sweet clover, 30-50 kg/mu radish leaves, 30-40 kg/mu dried Sphagnum moss, 60-80 kg/mu potassium nitrate, 70-100 kg/mu ammonium sulfate, 50-70 kg/mu potassium dihydrogen phosphate, 10-20 kg/mu soil conditioner, 30-60 kg/mu mushroom residue, 60-80 kg/mu sweet Sorghum stem, and 30-40 kg/mu straw mushroom, (b) performing treatment of plant before planting by cutting long roots, and curled portion of roots caused due to mechanical damage, and treating roots with aqueous slurry of fertilizer to improve the survival rate of plant, (c) planting treated plants by leaving a spacing of 2 mx 2 m, and pouring water to root of plant, (d) applying 7-10 kg urea fertilizer to plants after shoots grow to a height of 3-4 inches, applying fertilizer again after shoots grow to a height of 5-6 inches, where fertilizer is applied 30 cm away from plant to avoid burning of mulberry plant, (e) pruning mulberry branches after reaching a height of 40 cm, leaving 3-4 stout branches per plant, and cutting base to a height of 15-20 cm, (f) applying 15-20 kg fertilizer per acre during flowering period (end of March to early April) to enable rapid expansion of young fruit, where the fertilizer is 0.3% potassium dihydrogen phosphate, and (g) controlling pest and disease damage by spraying 500 times 50% carbendazim WP on branches, where spraying is done for 2-3 times for every 6 days, or for every 4 days.
