NOVELTY - Planting peanuts in saline-alkali salt, involves applying pesticides to soil, exposing soil to sunlight for 3,days to kill pests, adding soil modifying agent that comprises 150-210 Kg/fern plant, 200-280 Kg/ phosphogypsum, 50-70 Kg/ ammonium chloride, using rotatory cultivator for tilling of farmland, watering soil, allowing wet soil fermentation reaction for 7-10 days, seeding of 20 kg of good quality, high yield peanuts, sowing in two rows on ridge line and fertilizing every month by applying 4-5 Kg/ nitrogenous fertilizer and 10-15 Kg fertilize.    USE - Planting peanuts in saline-alkali soil (claimed).    ADVANTAGE - The method for growing peanuts in saline-alkali salt is simple, applied to soil that contains industrial waste phosphogypsum, ferns and other fermented organic fertilizer, cost effective, reduces soil pH value by reducing total salt content, improves nutrient content of soil required for growth of various crops especially well suited for peanut greatly improving yield and peanuts quality.    DETAILED DESCRIPTION - Planting peanuts in saline-alkali salt, involves applying pesticides to soil, exposing soil to sunlight for three days to kill pests, adding soil modifying agent that comprises 150-210 Kg/fern plant, 200-280 Kg/ phosphogypsum, 50-70 Kg/ ammonium chloride, using rotatory cultivator for tilling of farmland, watering soil, allowing wet soil fermentation reaction for 7-10 days, seeding of 20 Kg of good quality, high yield peanuts, sowing in two rows on ridge line with width 20 cm and 2 cm depth of planting, fertilizing each month by applying 4-5 Kg/ nitrogenous fertilizer and 10-15 Kg fertilizer during growing period, regular spraying 0.3-0.4 % of monopotassium phosphate thrice in 7 days for conventional pest management till maturity of peanuts. An INDEPENDENT CLAIM is, included for method of preparing fermented fern plant involves:    (A) picking fern plant and cutting it into 2-4 cm long;    (B) immersing them in fermentation pool that contains cellulose decomposing enzyme;    (C) stirring in every 4 days;    (D) fern plants taken out after 30-40 days;    (E) cleaning, drying under sun; and    (F) crushing to obtain fermented fern plant.
