Pre-Planting / Pre-Sowing Guidance

Pre-Planting / Pre-Sowing Care This stage is crucial for ensuring a healthy start by preparing the soil and seed material. Soil Testing and Correction: Conduct a soil test to determine nutrient (N, P, K) and pH levels. Potatoes prefer slightly acidic soil pH (5.2 to 6.4). Apply well-decomposed Farm Yard Manure (FYM) or compost during the final ploughing for improved soil structure and fertility. Deep Land Preparation: Plough the land deeply (20-25 cm) to ensure a loose, friable seedbed free of clods. This allows for unrestricted tuber development and proper aeration. Crop Rotation: Ensure the field has not grown potatoes or related crops (tomato, brinjal) for at least 2-3 years. This is essential to suppress soil-borne pests like Nematodes (especially Potato Cyst Nematode) and White Grubs. Seed Preparation and Treatment: Use only disease-free seed tubers (ideal size 30-45 mm). De-sprout (remove long, weak sprouts) and keep tubers in a well-lit, cool area (diffused light) for chitting (developing short, robust sprouts) 10-15 days before planting. Treat seed tubers with recommended fungicides before sowing to protect against soil and tuber-borne diseases like Black Scurf and Dry Rot. Fertilizer Application: Apply the full dose of Phosphorus (P) and Potassium (K), along with a portion of Nitrogen (N), as a basal dose during the final land preparation or at planting.
