Virus problem and solution in mungbean

28/04/2019Posted on
  • During the stages of this crop, the symptoms of yellow mosaic, leaf curl, and crinkle disease can be seen by the virus.
  • The grain yield losses range from 2-95% in mungbean depending on plant age and symptoms onset.
  • control of these diseases foliar spray of thiamethoxam 25% WG 60-100 gram per acre. OR imidacloprid 17.8% SL @ 100 ml per acre at 15 DAS.

How to improve production by improving soil health

28/04/2019Posted on

To increase the production by  50%, we should take three important measures in the soil

  • Increasing the amount of nutrients in the soil.
  • Improve the physical condition of the soil.
  • Maintaining the balance of pH in the soil.
  1. To increase the amount of nutrients in the soil
  • After harvesting the previous crop, the crop residues should not be destroyed by fire.
  • After harvesting, cultivate the farm twice, so that the crop residues dissolve and provide nutrients to the plants.
  • Apply FYM @ 10 t/acre OR Vermicompost 2.5 t /acre + SSP @100 kg apply at the time of ploughing in the field.
  • Apply (1 kg of micronutrients + PSB 2 kg + KMB 2 kg + NFB 2 kg + ZnSB 4 kg + Trichoderma 2 kg) per acre on sowing time.

2. To improve the physical condition of the soil –

  • If the farmer having an adequate amount of water plough the field after harvesting and mix speedkampost @ 4kg/acre, after mixing provide one irrigation.
  • In 15-20 days, crop residues with the help of Speed ​kampost disintegrate well and improve soil structure.
  • 3. For the pH balance of soil –
  • To control the soil pH, slow-release nutrients should be used.
  • Fertilizers should be used in a balanced amount of more Acid and Base content.
  • The soil pH rage maintains between 6.0 to 7.0 for good production of crops.
  • For the improvement of acidic soil, the amount of calcium carbonate should be applied according to the soil test report.
  • For the improvement of alkaline soil, gypsum should be applied according to the soil test report.

Yellowing leaves may cause more damage in Brinjal

27/04/2019Posted on
    • Brinjal is one of the most widely grown vegetables in the world including India.
    • Yellowing on the leaves of brinjal may indicate a more serious problem.
    • Yellowing in the leaves can be due to various reasons such as insect (spider, bug, and juice insect), diseases (wilt and viral-borne disease) and deficiency of nitrogen, etc. Due to yellowing in plants, the yield is less and consequently, there is an economic loss.
    • To increase the availability of nitrogen, mix nitrogen fixation and phosphorus-soluble bacteria with nitrogen fertilizers in the field @ 2 kg/acre.
    • To protect the brinjal crop from insect problem, can spray propergite 50% EC @ 400 ml (for spider) and Dichlorvos 76% EC @ 300 ml (for lace bug) per acre.
    • To prevent yellowing from diseases, spray carbendazim 12% + Mancozeb 63% WP @ 200 gram and streptocycline at 20 gram/acre, and control the disease spreading insects.

Signs of Boron deficiency in the crop and ways to prevent it

26/04/2019Posted on
  • Symptoms are variable, depending on the crop and the growing conditions, but generally, they are visible first on new leaves.
  • The first sign is usually the discoloration and thickening of young leaves.
  • At greater severity, the deficiency causes necrosis of the growing points.
  • Boron deficiency is usually observed in soils with a high pH because in these conditions this element is in a chemical form that is not available for the plant.
  • Soils with low organic matter content (<1.5%) or sandy soils (prone to nutrient leaching) are also susceptible to boron deficiency.
  • Preventive Measures for boron deficiency.
  • Avoid soils with high pH.
  • Avoid high air humidity and low soil moisture. Do not over-fertilize or lime the soils.
  • Avoid over-watering of the crops.
  • Regular testing of soil and keep the full details of the level of nutrients in your area.

Management of stem fly in the mungbean

25/04/2019Posted on
  • Damage in yield by the stem fly in the mungbean crop has been reported to be  24-37%.
  • In India Stem fly infestation during the germination stage is predominant affecting crop produce posing a serious concern.
  • As this pest attacks during the initial stage of germination which is generally 4 weeks after sowing, this infestation results in wilting of leaves leading to crop loss.
  • Foliar spray of imidacloprid 17.8% SL @ 100 ml/acre OR Bifenthrin 10% EC @ 300 ml per acre may be sprayed to control stem fly.

How much harmful stem borer in sweet corn and how to control ?

25/04/2019Posted on
  • In India, about 13.2% of economic yield losses have been reported due to insect-pests attack and disease incidence.
  • In different agro-climatic zones of our country, this insect has been reported as the cause of loss of 26.7 to 80.4% of the total yield of maize.
  • Young larvae inter the midrib of the stem and feed the internal tissue and make a shot hole on the stem of the plant. (Causing a condition referred to as “dead heart”).
  • It damaged the crop from 10-12 DAS to till harvesting.
  • Soil application of carbofuran 3% G@ 5-7 kg per acre.
  • The spray of Dimethoate 30% EC@180-240 ml per acre.

Importance of Zinc

25/04/2019Posted on
  • India’s agricultural land has a deficit of zinc is 50%, which will be up to 63% by 2025.
  • Studies have shown that due to zinc deficiency in the soil, there is a lack of zinc in the crops produced in that soil, (according to IZAI) 25% of India’s population is lacking in zinc.
  • Zinc needed strongly for the development of the plant . it is one of the eight essential micronutrients.
  • In India, zinc (Zn) is now considered as the fourth most important yield-limiting nutrient in agricultural crops
  • In plants, zinc is a key constituent of many enzymes and proteins. It plays an important role in a wide range of processes, such as growth hormone production and internode elongation.
  • Deficiency in zinc might result in a significant reduction in crop yields and quality. In fact, yield can be reduced by over 20% before any visual symptoms of the deficiency occur.
  • Young leaves of zinc-deficient plants are small with yellow interveinal mottling.
  • Necrotic interveinal areas occur in expanded and older leaves.
  • oil application of zinc sulfate @ 20 kg/acre is recommended.

How to Save 20-25% of Nitrogen Fertilizer

23/04/2019Posted on

Azotobacter free-living nitrogen fixation aerobic bacteria.

  • It stabilizes atmospheric nitrogen into soil.
  • Using of this bacteria, the requirement of Nitrogen Fertilizer (Urea) decreases up to 20-25 %.
  • It secretes various types of vitamins and gibberellins in the roots of plants, which increases the accumulation of seeds (germination) and good growth of roots and the capacity of absorbing micro-nutrients and water in plants.
  • Seed Treatment :- Azotobacter (CFU 1 X108 ):- 4-5 ml/kg seed.
  • Soil Application:- one liter of Azotobacter (CFU 1 X108 ) mixed with 40-50 kg well-decomposed FYM/Vermicompost and broadcast in soil or can broadcast 45 DAS in soil.
  • Drip Irrigation:- one liter of Azotobacter (CFU 1 X108 ) mixed with 100 ltr water and apply within drip.

Suggestions for control of yellowing of Coriander Leaves

22/04/2019Posted on
  • Coriander is an important crop of spices, all parts of which use stems, leaves, and seeds.
  • If its management is not correct, then it becomes yellow, which reduces production.
  • For its management, Apply Nitrogen Fixation Bacteria and Phosphorus Solubilizing Bacteria with Basal Dosage mixed up well in the field at the rate of 2 kg per acre.
  • Due to the lack of nitrogen in the soil and the problem of disease and insects, coriander leaves turn yellowish.
  • Apply Thiophanate methyl 70% wp @ 250-300 g and chlorpyrifos 20% EC @ 500 ml per acre with irrigation.
  • After this drenching, apply 19:19:19 @ 500 gm per acre.
