Weather based Agro-Advisories (for the period ending on 30th April, 2017)

Advisory based on advices received from the subject matter specialists of agro-advisory committee:

 

1.      Keeping in view of dry weather and temperature, light irrigation is advised in all vegetable and fodder crops. Irrigation should be done in the morning or evening hours.

2.      Before keeping grains in store, it should be properly cleaned and dried to the recommended level (12%) of moisture content. Storage should be properly cleaned by removing all the grains and other storage matter of previous crop. Cracks and crevices of the walls should be cleaned and repaired. The gunny bags should be dried in the sun so that eggs and pupating stages of insects as well as inoculums of diseases get destroyed. Farmers may store their seeds in Pusa Kothar as in these structures germinating qualities of seeds are maintained. Storage of grains should be done in morning hours.

3.      Farmers are advised for preparation of nursery for chilli and brinjal.  Farmers are advised to use shed nets, it helps in reducing soil borne disease and thus produce healthy seedlings. For proper germination soil should have sufficient moisture.

4.      Present weather conditions are highly conducive for nursery and field preparation for early cauliflower.Farmers are advised to carry out solarization of prepared nursery beds by covering with thin plastic sheets of 20-30 mm thickness.This operation will help in reducing microbes responsible for disease development in seedlings.Seed should be sown in nursery after treatment with captan or thiram.For proper germination soil should have sufficient moisture.

5.      Field preparation for sowing of pigenpea may be done in this week. Farmers are advised to procure good quality seeds from certified source. Before sowing pigeon pea seeds should be treated with crop specific Rhizobium culture and Phosphate Solubilizing Bacteria. This treatment increases the crop production. Pigenpea varieties- Pusa 2001, Pusa991, Pusa992, Paras, manak, UPAS 120.

6.      In cucurbitaceous crops, if attack of red pumpkin beetle is found than; Spraying of Diclorvos 76 EC (DDVP) @ 1 ml per litre of water is advised. To protect beneficial insects, minimum use of pesticide should be done.

7.      In present weather conditions constant monitoring of lady finger crop against attack of mite is advised. Spraying of Ethion @ 1.5-2 ml/litre of water is advised. Due to prevailing high temperature, light irrigation at short interval is advised.

8.      To control shoot and fruit borer in brinjaland tomato crops, infested fruits and shoots should be collected and buried inside the soil. Installation of pheromone trap @ 2-3 traps per acre of crop field is advised for monitoring the borer. If pest population is above ETL, spraying of Spinosad 48 EC @ 1 ml /4 litres of water is advised.

9.      Sowing of gwar, maize, bajra, cluster bean as fodder crops may be done during this week. Before sowing seeds should be soaked in water for 3-4 hours. Adequate moisture should be maintained for maximum germination of seeds. Sowing should be done at a depth of 3-4 cm and at row to row spacing of 25-30 cm.

10.  Sowing of green manure crop is advised in those field where harvesting of rabi crop is completed. Sowing of cluster bean, daincha, senai, lobia etc may be done for green manure. For proper germination and growth of the crop soil should have sufficient moisture.

11.  Deep ploughing of fields after harvesting of rabi crops is advised so that eggs and pupating stages of insects and weed seeds are destroyed due to high day temperature.

12.  During this weather conditions when farm operations are less, farmers are advised to test their soil from certified agencies.
