Weather based Agromet-Advisories (for the period ending on 23rd January, 2019)

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

1.      Keeping in view of rainfall forecast in next three days Farmers are advised to stop irrigationand all type of sprays in all standing crops and vegetables.

2.      In wheat crop if symptoms of termite appear than application of Chlorpyriphos 20 EC @ 2.0 litre should be done with irrigation.

3.    In present weather condition farmers are advised to do constant monitoring of aphid in mustard crop. In early stage cut and destroy the infested part of the plant.

4.      For monitoring of the pod borer in the gram crop, farmers are advised to install Pheromone trap @ 3-4 traps per acre, if flowering has reached 20-25%. “T” shaped bird perches in and around crop field to be installed for controlling insect population.

5.   Keeping weather in view, Nursery preparation should be done for chili, tomato and brinjal crops in poly house. Prepare seedling of early cucurbitaceous crops in small polythene bags in poly houses.

6.  In present weather conditions transplantation of healthy seedlings of late varieties of cabbage, cauliflower, knolkhol etc. may be done on ridges.

7.     In present weather conditions, sowing of spinach, coriander, fenugreek may be done. Foliar spray of 20 kg urea per acre may be done to maintain foliage health.

8.      Weatheris suitablefor growing of carrot seed crop in this week. For carrot seed production, if carrot crop raised from high quality and good varieties carrot seeds is 90-105 days old at the time of harvesting of crop in the first fortnight of January than farmers should select good lengthy and vigorous carrot having less numbers of leaves. In these selected carrot farmers should cut the leafs after leaving 4  inch and also cut the lower portion of the carrot root after leaving the top upper 4 inch and transplant at 45cm row to row distance and 6 inch plant to plant distance. After that irrigation should be done.

9.      Keeping in view of optimum weather conditions, Farmers are advised for transplantation of onion seedling in this week. Seedling should not be older than six weeks. Transplanting should be done in small beds. Deep transplanting should be avoided. Apply 20 ton well decomposed FYM, 10-15 day before transplanting with 20 kg nitrogen, 60-70 kg phosphorus and 80-100 kg potash at the time of last ploughing. With a spacing of 15 cm (row–row) x 10 cm (plant-plant). Onion crop requires light and frequent irrigation at an interval of 10-12 days as per requirement.

10.  Farmers are advised to do constant monitoring of timely sown onion crop against attack of thrips. If infestation is more than spraying of Imidacloprid @ 0.5 ml per litre of water with sticky material (Tipol 1.0 gram /litre) should be done when sky remains clear.

11.  Farmers are advised to install pheromone traps @ 3-4 traps per acre for monitoring of the pest population for diamond back moth in cole crop, pod borer in pea and fruit borer in tomato.

12.  In present weather, wrapping of plastic sheets around mango trunk should be done for preventing climbing of young (nymphs) mealy bugs. Apply grease to seal any cracks in the polythene sheets.

13.  In present weather, constant monitoring of inflorescence rotting disease in marigold crop is needed. If symptoms are found, spraying of Bavistin @ 1 gram\litre water is recommended when sky remain clear.
