Weather based Agromet Advisories (for the period ending on 30th July, 2017)

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

 

1.      Farmers are advised to conserve rainwater in the paddy field judiciously by proper bund making. Bunds should be higher and broader for maximum rain water harvesting.

2.      The farmers, whose transplanted paddy crop is 20-25 days old, should apply nitrogen at the rate of 30-40 kg. /ha.

3.      In the paddy field if plants started turning yellow i.e. top leaves turned yellow and bottom leaves remained green, farmers may spray zinc sulphate solution (6.0 kg zinc sulphate dissolved in 300 litres of water / ha.).

4.      Keeping in view of rain for next five days farmers are advised for sowing of maize on ridges as earliest. Recommended Hybrid: AH-421, AH-58 Composites: Pusa composite-3, Pusa composite-4. Seed rate 20 kg/ha. It is also advised to maintain row to row spacing of 60-75 cm. and plant to plant 18-25 cm. Spray of Atrazine 1-1.5 kg a.i/ha. in 800 lit. of water is recommended just after sowing for effective weed control in maize when sky is clear.

5.      Farmers are advised for sowing of bajra (Hybrid Bajra Pusa-605, Hybrid Bajra Pusa-415, Composite Bajra Pusa-383, HSV-67) as earliest. Seed treatment is required for protection against Ergot and Downey mildew. Seeds should be put in 10 % salt solution, light and damaged seed should be removed and remaining seed should be dried and treated with Redomil 2.0 gm/ kg seed to protect from seed borne diseases.

6.      Sowing of green gram and black gram should be done this time and seeds should be procured from certified agency.

7.      Farmers are advised for constant monitoring of cotton crops against sucking pests and Mealy bug, if the insect population is above ETL then spray of Imidacloprid 0.5 ml./litre of water is recommended when sky is clear. Installation of pheromone trap @ 2-3 traps per acre of crop field is advised for monitoring and control of insect of cotton crop.

8.      This is most suitable time to grow fodder sorghum specially Pusa chari-9, Pusa chari-6 or other hybrids. Seed rate should be 20 kg/ha.

9.      Transplanting of brinjal, tomato, chilli and early cauliflower on ridge is advised for those farmers whose seedlings are ready. Proper drainage should be done in the fields.

10.  Farmers are advised for sowing of guar (Pusa Navbahar, Durga Bahar), radish (Pusa Chetki), cluster bean (Pusa Komal), Beans (Pusa Sem 2, Pusa Sem 3), spinach (Pusa Bharti), amaranths (Pusa lal Chaulai, Pusa Kiran) and ladyfinger (Pusa A-4) on ridges. They are also advised to procure good quality seeds from certified sources.

11.  Bees are important source for pollination in vegetable crops therefore, bee keeping should be promoted. Constant monitoring of the crops should be done for insect and disease. Farmers should take advice from the nearest KVKs for use of insecticides and other information regarding the crops. Fruit flies infected fruits should be picked and buried in the soil. Protection of cucurbitaceous crops against fruit fly by use of bait trap (mixing juggary 10 % with Malathion 10 % and putting at different corners of the field) is advised.

12.  The creepers of cucurbitaceous cropsshould be lifted above the ground on a trellis made of bamboo. Proper drainage should be done in the fields.

13.  Rainy season onion should be transplant or direct sown in the prepared fields.

14.  Farmers are advised to prepare marigold nursery (Pusa Narngi) in net house. Proper drainage should be done in the fields.

15.  Farmers are advised for sowing of sweet corn (Madhuri, Vin orange) and baby corn (H.M-4) in raised bed.

16.  Farmers should do weeding and hoeing in the standing crops to protect them from weeds keeping in mind their rapid growth in the rainy season.

17.  Farmers who want to establish new orchard gardens (Mango, citrus and guava) are advised for transplanting of plants from recognized sources.
