Weather based Agro-Advisories (for the period ending on 26th April, 2017)

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

 

1.      Keeping temperature in view, Farmers are advised for frequent irrigation in vegetables nurseries and orchards. Farmers are also advised to protect vegetables nurseries and orchards against hot winds by physical barrier and shed net.

2.       Before storage, grains should be properly cleaned and it should be dried to the recommended level of moisture content(less than 12%). Godowns 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 and whitewashing should be done. Those who can afford are advised to spray 0.5 % malathion solution and keep the chamber closed for 7-8 days. The gunny bags should be dried in the sun so that eggs and pupating stages of insects as well as inoculum of diseases get destroyed.

3.      Sowing of summer green gram is advised in those fields where harvesting of rabi crop is over. Variety: - Pusa Visal, Pusa Ratna, Pusa 5931, Pusa Baisakhi, PDM-11, SML-32, SML-668, Samrat. Seed treatment with crop specific Rhizobium culture as well as phosphorus solubilishing bacteria is also advised. Farmers are advised to ensure proper moisture before sowing for optimum germination.

4.      After harvesting of Rabi crops farmers are advised for deep ploughing of fields. Because high temperature helps in destroying the eggs and pupating stages of insects and weed seeds.

5.      After harvesting of Rabi crops farmers are advised to test their soil from certified agencies and to do laser leveling in their field if required.

6.      For green manure, sowing of green gram, cluster bean, senai, gwar etc may be done during this week. Seed rate for sanai is 60-70 kilogram and that of dhaicha is 50-60 kilogram per hectare. For adequate germination proper moisture should be maintained.

7.      Sowing of fodder crops (gwar, maize, bajra, and 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.

8.      Field preparation should be done for sowing of pigeon pea and cotton in this week. Farmers are advised to procure good quality seeds from certified source.

9.      Harvesting of spinach should not be done by cutting but it should be uprooted and sent to market.

10.  Keeping in view of forecasted high temperature, farmers are advised for harvesting of mature vegetables at morning and evening and after harvesting of crops, keep it in the shade.

11.  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.

12.  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. Due to prevailing high temperature, light irrigation at short interval is advised.

13.  To control shoot and fruit borer in brinjaland tomato crops, infested fruits and shoots should be collected and buried inside the soil. If pest population is high, spraying of Spinosad 48 EC @ 1 ml /4 litres of water is advised.

14.  Farmers are advised to give light irrigation in the mature onion and garlic crops one week before digging.
