Ladyfinger Cultivation Technology from Sowing to Pest Management on Complete information

The vegetable commonly known as "ladyfinger," or okra, is a popular choice among consumers. Okra holds a prominent position in the realm of vegetables. Primarily, okra contains protein, carbohydrates, and minerals such as calcium, phosphorus, along with vitamins A, B, C, thiamine, and riboflavin. It offers adequate amounts of vitamins A and C. Farmers stand to gain greater profits by cultivating okra as a cash crop. Okra fruits boast a high iodine content. Its cultivation is feasible in all districts of the region. Agricultural scientists have developed hybrid okra varieties to enhance production and to secure okra yields under varying weather conditions. These varieties exhibit increased tolerance to diseases like yellow vein mosaic virus. Okra cultivation is prevalent in warm and tropical regions worldwide.

Soil and Field Preparation for ladyfinger Cultivation:

Ladyfinger cultivation thrives in warm and humid environments. A temperature range of 27-30 degrees Celsius is optimal for seed germination. This crop can be grown during both the summer and monsoon seasons. Okra can be cultivated in various soil types that allow for efficient water drainage. Ideally, the soil pH level should fall between 7.0 to 7.8. The land should be plowed two to three times, leveled, and ridged to ensure uniformity.

Optimal Varieties of ladyfinger:

1. Pusa-E4: This is an advanced variety of okra. It exhibits resistance to aphids and jassids. It is tolerant to wilt and yellow vein mosaic virus. The fruits are of medium size, deep green, and measure 12-15 centimeters in length. The average yield is 10 tons per hectare in summer and 15 tons per hectare in monsoon.
2. Parbhani Kranti: This variety is resistant to wilt. Fruiting begins approximately 50 days after sowing. The fruits are deep green and measure 15-18 centimeters in length. The yield ranges from 9-12 tons per hectare.
3. Arka Anamika: This variety is developed by the Indian Institute of Horticultural Research, Bangalore. The plants are tall, ranging from 120-150 centimeters, with well-branched stems. The long fruit pods facilitate easy harvesting. It can be grown in both seasons, with a yield of 12-15 tons per hectare. 
4. Seasonal OH-517: This variety can be sown between December and April. The plant height is moderate, and the fruits are dark green. They have no spines, making them easy to harvest.

Method of Sowing and Seed Quantity:

Prior to sowing seeds, the field should undergo plowing 2-3 times. For annual okra, maintain a row spacing of 40-45 cm and a plant spacing within rows of 25-30 cm. Before sowing, treat okra seeds with 3 grams of mancozeb carbendazim per kilogram of seeds. Divide the entire field into appropriately sized plots to facilitate irrigation. It's advisable to sow okra in raised beds to prevent waterlogging during the rainy season. In irrigated conditions, 2.5 to 3 kg of seeds per hectare are required, while in unirrigated conditions, 5-7 kg per hectare is necessary. For hybrid varieties, 5 kg of seeds per hectare is sufficient. Okra seeds are sown directly in the field.

Irrigation of ladyfinger:

ladyfinger should be irrigated at intervals of 10-12 days in March, 7-8 days in April, and 4-5 days in May-June.

Preparation of Nursery for ladyfinger: For okra nursery preparation, coco peat should be used in polythene bags through portering, and seedling trays should be placed in a low tunnel. When the okra seedlings have 3-4 leaves, they can be transplanted into the field. The depth of the nursery portering should be 2.5 to 3 inches. The temperature should be appropriate when transplanting okra seedlings. Okra transplantation is done in the last week of February.

Pest Management: 

1. Aphids and Fruit Borers: This pest is more prevalent during the rainy season. Its attack on flowers results in premature falling before fruit formation. The fruits become misshapen and unfit for consumption. To control it, spray a solution of 2.5 milliliters per liter of water containing either 25% EC quinalphos, 20% EC chlorpyrifos, or 50% EC profenofos.
2. Red Spider Mite: This pest pierces leaf cells with its mouthparts, extracting sap and causing yellowing and distortion of affected leaves. To manage it, mix 2.5 grams of soluble sulfur per liter of water and apply as a spray.
