- Azotobacter is an independent nitrogen fixation bacteria.
- This bacterium keeps the nitrogen of the atmosphere continuously stored in the ground.
- Use of this does not cause yellowing of leaves in cucurbit crops.
- In cucurbit crops , fruit development and growth of plants are good.
- When it is used, 20% to 25% of nitrogen is required per crop.
- These bacteria increase germination percentage of seeds.
- Helps to increase the quantity of roots and length of stem.
Controlling leaf miner can increase production in melon crop
- Affected plants during the growing season to be withdrawn and destroyed.
- Spray Wapkill (Acitamprid) @ 100 gm/acre or
- Confidor(Imidacloprid ) @ 100 ml + 250 gram beauveria bassiana/acre or
- Spray Thiamethoxam 12.6% + Lambda Cyhalothrin 9.5% ZC @ 100gm/acre or
- Spray Abacin (Abamectin 1.8% EC) @ 150 ml/acre
Identification of leaf miner on muskmelon crop –
- Adults leaf miners look like small black and yellow flies.
- Larvae exit from the leaf after completion of their development and then pupate axles on plants.
- Females puncture the leaf to feed plant sap and lays eggs within the leaf tissue.
- This damage restricts the plant growth and results in reduced bulb yield and loss of vigour.
- Tunnels or mines can be seen in the leaves.
Pinching in watermelon and muskmelon crop
- Pinches are made to prevent overgrowth of watermelon from the plant.
- When there is enough fruit on the oxen of watermelon, then there should be a solution to pinch, which can prevent the bull from failing.
- Pinching and cutting unwanted wounds results in good nutrition for the fruit and the development of the fruits is good.
- If there are too many fruits on a vine, then remove the small and weak fruits so that the normal fruit gets better.
- By removing unnecessary branches, watermelon gets complete nutrition and it grows very fast.
Management of fusarium crown and foot rot disease in muskmelon crop –
- Destroy infected plants and plant debris.
- Use of disease-free seed.
- Seed treatment with carbendazim @ 2 gm/kg seeds before sowing.
- Use Propiconazole 25% EC @ 80-100 ml/acre when the disease appears on the muskmelon plant.
Identification of fusarium crown and foot rot disease in muskmelon crop
- Diseases are more common in sandy soil.
- The plant shows a distinctive dark brown necrotic rot of the crown and upper portion of the taproot.
- This decay extends around the stem and girdles the plant.
- The affected area turns soft and mushy
- affected plants show wilting symptoms
Harvesting of muskmelon
- Depending on the variety and agro-climate, melon will be ready to peak fruit in about 110 days.
- The phase of maturity is usually identified with the outer colour change of the fruit, and if the peel becomes soft, Ripe fruit is easily removed from the vine.
- The melon is harvested by hand.

ShareIrrigation management in muskmelon
- During summer, irrigate the crop every week.
- The irrigation should be as light as possible.
- At the time of fruit maturity water should be given when it is very necessary.
- Overflooding should be avoided as the fruit oncoming contact with moist soil gets spoiled.

ShareSowing and seed rate in muskmelon
- Dubbing method and transplantation method is used for sowing melon.
- Sow the melon seeds on a 3-4 meter wide bed.
- Sow two seeds together and keep a distance of 60 cm between beds.
- Insert the seed at depth of about 1.5 cm.
- For sowing in one acre land 300- 400 gm seeds are required.

ShareControl of fusarium wilt in muskmelon
- Muskmelon plants get infected early in the season and they do not produce more fruit.
- The first signs of fusarium wilt appear on older leaves. Leaves are yellowing and dry. The symptoms of this disease are most clearly seen during the heat of the day.
- Brown cracks are visible in the stem, from which the brown red-coloured exudate.
- Use the disease-free seed for sowing.
- Plough the fields deep, destroy the weeds and make proper drainage.
- For the effective control of fusarium wilt use the Propiconazole 25% EC @ 200 ml/acre or thiophanate-methyl 70 % WP @ 250-500 gm/acre.
