Agri Panchangam

Crop Name:  Potato

Agriculture Panchangam
Soil climatic conditions:
1.) Potatoes require cool climate. Optimum day/night temperature is 25/12oc. 2.) Potatoes grows best in well-drained soils with pH 5.2-7 is required.
Seed Rate:
1.) Potato sprouted tubers (30-40g with 2-3 Eyes/tuber) 6-8 quintals/Acre.
Seed Treatment:
1.) Seed dormancy: 100g Thiourea + 10mg Gibberellic acid in 10 lit water. After 24-48 hours use tubers for sowing. 2.) Seed treatment with Mancozeb 3g/lit water keep for 30 min.
Field Preparation Uses:
1.) Plough the land 4-5 times & add 10-12 tons of FYM, during last the ploughing & make channels.
Types Of Cultivation:
1.) Sowing the sprouted tubers in the main field, planting is done either at the top (or) on the sides of ridges.
1.) Spacing should be 50cm x 20cm for row to row and plant to plant.
1.) Maize can be used as intercrop in Potato with ratio of 2:1. 2.) Cluster bean, Cabbage & Knol khol can be used as intercrops in Potato with the ratio of 1:1.
Weed Management:
1.) At 2-3 days seedling crop spray Alachlor 50% EC lit/Acre and Metribuzin 300g/Acre can also be used to remove weeds.
Water Management:
1.) Give irrigations according to the climatic conditions. 2.) Irrigations are given at before germination with 7-8 days interval, Tuber formation stage with 4-5 days interval.
Nutrient Management:
1.) 40kg urea, 150kg SSP, 30kg MOP add during the last ploughing. 2.) After 30th day crop add 40 kg Urea, 50th day crop add 20 kg Urea and 30kg MOP.
Intercultural Operations Uses:
1.) Earthing up should be done 3-4 days after 30 days seedlings. It is an important of the growing process. It involves drawing mounds of soil up around the plant to prevent new tubers from growing, turning green & Poisonous.
Flowering Maturity Stages:
1.) Potato plants produce flowers during the end of their growing season. Potato plant flowering is a normal occurrence, but the flowers usually just dry up & fall off rather than producing fruit. 2.) Potatoes are harvested when they attain sufficient size. Early varieties at 57 to 100 days, late varieties at 120-160 days. 3.) Skin slipping from the tubers, starch content & leaf senescence (or) top drying are the harvest indices.
Harvesting Methods Uses:
1.) Harvesting can be done by digging with spade (or) other hand tool. 2.) Harvesting should be done when there is optimum moisture in the soil.
Yield For Different Cultivation Methods:
1.) On an average of 10-14 tons/Acre.
Post Harvest Handling:
1.) Drying: Potatoes are dried, to remove excess moisture at the surface of the tubers and improve their keeping quality. 2.) Curing: Before placing the potatoes in storage, the tubers should be cured. Ideally, curing should be done at 15-20?c for suberisation. Healing of minor cuts & bruises & thickening of the skin occurs during the curing process. 3.) Sorting & Grading: Grade the tubers on the basis of quality factors & Sort out bad, rotten from the good produce. 4.) Packaging: Pack in bags for convenient handling. 5.) Storage: Place the produce in appropriate stores to avoid contamination & spoilage.
Organic Products Required:
1.) FYM: Reduces the usage of 20-25% Nitrogen Fertilizer. 2.) Inoculation of tubers with Bio fertilizers like Azotobacter and Phosphobacteria which increases numbers of tubers, tuber weight per plant, total tuber yield.
