Infestation of sucking pests in okra crop

Infestation of sucking pests in okra crop

  • In the bhindi crop, the attack of sucking insects such as aphids, jassids, whitefly, mites etc. is commonly seen.

  • Both the nymphs and adults of all these sucking insects, suck the sap from the soft parts of the plants, flowers and leaves of the okra crop. Due to this, the growth of plants stops, the leaves wither and turn yellow, if there is more attack then the leaves also fall.

  • These insects also secrete a sticky substance on the infected part, which can increase fungal infection and also hinder photosynthesis.

  • Out of these, the whitefly is a vector of yellow vein mosaic virus disease of okra.   

  • For Aphid/ jassid management use Acephate 50 %+ Imidacloprid 1.8 % SP @ 400 gm or Acetamiprid 20 % SP @ 100 gm or Imidacloprid 17.8% SL @ 100 ml/acre.

Precautions to be taken while storing Kharif Onion

Precautions to be taken while storing Kharif Onion
  • Onion is in demand throughout the year. Hence, storage of onion tubers is essential for the supply of the whole year. In our country, 30-40 percent of onions get rotten due to inadequate storage facilities and unseasonal rains.

  • Most of the farmers store Rabi onions only because Rabi onions have better storage capacity as compared to Kharif and late Kharif onions.

  • The plants should be dried in the field till the leaves turn yellow and the neck becomes thin, then dried in shade with adequate ventilation. Drying in the shade protects the tubers from the harsh rays of the sun, improves the colour and dries the outer surface. 

  • Sometimes the tuber gets wound with a spade or shovel. While sorting the tubers, separate the stained tubers. Later, by causing rot from these bad tubers, other tubers also start rotting.

  • For good storage of onions, 50 kg jute/sackcloth/plastic mesh bags or plastic/wooden baskets should be used.

  • Onion after packing should be kept in the storage room up to 5 feet in height so that it is easy to remove.

  • The temperature of the warehouses for good storage is 30-35˚C and the relative humidity should be 65-70%.

Azolla, a nutritious aquatic fodder for livestock

Azolla a nutritious aquatic fodder for livestock
  • Animal husbandry plays an important role in our country’s economy. The size of the farmer’s holding is getting smaller day by day and the farmers are finding themselves unable to cultivate green fodder even after wanting it. This is the reason that in the country, the availability of green fodder is becoming very less.

  • In such a situation, Azolla is a good option in the form of green fodder for animals.

  • Like growing green fodder crops, fertile land is not required to grow Azolla. It can be grown as aquatic fodder by digging a pit in any type of land and filling it with water. If the land is sandy, then by laying a plastic sheet in the pit, Azolla can be grown by filling it with water. 

  • Azolla is ideal fodder for cows, buffaloes, hens and goats.

  • By feeding Azolla, the milk production of lactating animals increases.

  • A hen which normally lays 150 eggs in a year, can give 180-190 eggs in a year by giving it to the Azolla diet.

  • Not only this, but Azolla has also proved beneficial in fish production.

  • Being a good quality, digestible and abundant protein source, Azolla is no less than a boon to the farmers.
