Potato

Land Preparation
For a successful tuberization of the potato crop, a well-pulverized seed bed is necessary. The soil is exposed to the sun and dug up to a depth of 24 to 25 cm. The soil should offer least resistance to tuber development and a higher pore space. The soil should be combined with well-decomposed FYM (25–30 t/ha) during the final ploughing.
Seed Rate and Spacing
Choose high yielding varieties of pure, healthy, 40–50 gms seeds that are free from pests and diseases. About 1.5 to 2.5 tonnes of seed should be sown per hectare. The main crop should be kept at a row-to-row distance of 45 to 60 cm and a plant-to-plant distance of 15 to 20 cm.
Intercultural operation
Keeping the field weed-free during the crucial weed-competition period, which lasts up to 60 days, is crucial. Start your first round of hoeing on the 45th day without disturbing stolons. At the 60th day, you can start hoeing and earthing again.

Irrigation Management
The potato crop responds very well to effective water management. Water that is in excess must be removed. It is acceptable to irrigate lightly to moderate, but it's best to avoid flooding ridges with water.
Weed management
To provide the crop a competitive edge, weeds must be eliminated by the time the potato crop forms its canopy, which takes around 4 weeks following planting. Large weeds should be eliminated before the ridging operations start if they are present. Weeds between developing plants and at the top of the ridge should be pulled by hand or treated with herbicide after earthing up. Although hand weeding is an option, it is costly. As a result, a three-tine cultivator pulled by an animal that can cover one hectare per day is employed. For the control of annual grass weeds and broadleaf weeds, pre-emergence spraying with weedicides like Flucholralin (0.70-1.0 kg a.i/ha) or Pendimethalin (0.50 kg/ha) is advised.
Insect pest management

Cutworm

  1. Apply pheromone trap @ 12/ha
  2. Spray Chlorpyriphos 20 EC @1 lit/ha

Tuber moth

  1. Apply pheromone trap @15/ha.
  2. Spray Quinalphos 25 EC @2ml/lit of water to manage foliar damage

Whitefly

  1. Irrigation should be well timed.
  2. Spray Dimethoate 0.3%

White grub

  1. Summer ploughing should be done so that the pupa gets exposed.
  2. Spray Quinalphos 5% @25 kg/ha
Plant diseases management

Early blight

  1. Crop debris should be destroyed
  2. Spray mancozeb or Zineb

Late blight

  1. Crop debris should be destroyed
  2. Spray mancozeb

Black scurf

  1. Plant healthy tubers
  2. Seed tubers should be dipped in Agallol/Aretan 0.5% for 10 mins.

Bacterial wilt or Brown rot

  1. Certified seeds free from diseases should be used.
  2. Treatment of seed with Aretan/Agallol is advised.

Wart disease

  1. Healthy tubers should be used.
Harvesting & Post-harvest management

When the majority of the leaves have turned yellow-brown, the main crop is prepared for harvest. The tops are then cut close to the ground. After 8–10 days, the potatoes are removed from the field by ploughing.

Climate & soil

The best soil types for potatoes are medium loam soils with high humus content and well-drained sandy loam soils. Potatoes should not be grown on alkaline or salty soils. They thrive in soils with an acidic pH range of 5.0 to 6.5. Potato is a cool-season crop. It flourishes best in cool climates with adequate moisture and healthy soil. Soil temperature between 17-19 °C is necessary for optimum tuber growth.
