Weather based Agromet Advisories (for the period ending on 31st May, 2017)

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

 

1.      Present weather conditions are highly conducive for 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.

2.      Farmers are advised for preparation of nursery for chilli and brinjal.  It is also advised to use shed nets, which helps in reducing soil borne disease and thus produce healthy seedlings.

3.      Sowing of fodder crops (gwar, maize, bajra, cluster bean) may be done during this week. 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.

4.      Sowing of cotton may be done in this week. Adequate moisture should be maintained for maximum germination of seeds. Farmers are advised to procure good quality seeds from certified source. Recommended varieties: -H-777, H-974, H-1098.

5.      Sowing of pigenpea may be done in this week. Adequate moisture should be maintained for maximum germination of seeds.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 Solublesing Bacteria. This treatment increases the crop production. Pigenpea varieties- Pusa 2001, Pusa 991, Pusa 992, Paras manak, UPAS 120.

6.      Light irrigation is advised in all vegetable and standing crops at short interval. Irrigation should be done in the morning or evening hours.

7.      After harvesting of Rabi crops farmers are advised to do deep ploughing of fields. Because high temperature during this week is suitable for destroying the eggs and pupating stages of insects and weed seeds.

8.      Farmers are advised for harvesting of mature vegetables at morning and evening hours.

9.      Constant monitoring of the chilli crop against attack of mites is advised. Irrigation should be done in the morning or evening hours.

10.  Optimum moisture level should be maintained in cucurbitaceous crops by light and frequent irrigation as dry conditions may lead to poor pollination and thus drop in yield of the crop.

11.  After harvesting of mature okra application of urea @ 5-10 kg/ acre should be done. Constant monitoring of crop against attack of mite is advised. If population is above ETL then, spraying of Ethion @ 1.5-2 ml/litre of water is advised when sky remains clear. Due to prevailing high temperature, light irrigation at short interval is advised.
