Why, when and how to add mycorrhiza in the field :- 

17/10/2019Posted on
  • Improve plant root growth and development
  • Increase the uptake and mobilization of phosphate in all crops
  • Increase and facilitate nutrient and translocation from the soil and root cuticle parenchyma to xylem ,Phloem, elements like nitrogen, potassium, Iron, manganese, magnesium, copper, zinc, boron, sulphur and molybdenum.
  • Effective in overcoming the stress conditions like drought, disease incidence and deficiency of nutrients.
  • Enhance product quality and increase immune power of the crop
  • Its supplement root hair in water absorption hence prevents reduction in crop relative water content of cells and helps to overcome drought.
  • Soil Treatment – Mix Premium mycorrhiza 4 kg per acre in 50 Kg of well decomposed Fym/compost/vermi compost/field soil and incorporated in the soil before sowing/transplant.
  • Broadcast the above mixture in standing crop 25-30 days after sowing.

Aphid of Cucumber

17/10/2019Posted on

Nymphs and adults are both soft-bodied pear-shaped, blackish in colour.

  • Large colonies of nymphs and adults are found on tender twigs and shoots as also on ventral leaf surface sucking the vital sap from the tissues.
  • The affected parts turn yellow, get curled, wrinkled and deformed in shape and ultimately dry and die away.
  • Fruit size and quality is also reduced.
  • The aphids also exude copious quantity of honeydew on which sooty mould develops, in turn, hinder the photosynthetic activity of the vines, resulting in stunted growth.
  • The fruits covered by sooty mould look unattractive and lose their market value.
  • Profenophos 50% EC  @ 400ml/acre OR
  • Acetamipride 20 % SP 40-80 gm/acre OR
  • Acephate 50% + Imidacloprid 1.8% SP @ 300 gm/acre

Control of Fusarium Wilt in Gram

12/10/2019Posted on

Control of Fusarium Wilt in Gram:- Wilt in chickpea (Gram) caused by Fusarium oxysporum fungi. Warm and humid environment is favourable for it. the prevention of the disease, the following precautions have to be taken.

  • Conserved soil moisture during Monsoon.
  • Level up after deep ploughing (6-7 inch).
  • Use disease-free seed.
  • Follow 6-year crop rotations.
  • Grow resistant varieties.
  • Seed treatment with Carboxin 37.%+ Thiram 37.5% @ 2 gm /kg or Trichoderma viride @ 5 gm/kg.
  • Avoid sowing when temperature are high. Sown in second and third week of October.
  • Irrigation in November-December.
  • Apply Mycorrhiza @ 4 kg/acre at 15 days after sowing.
  • Spraying Thiaphanate methyl 75% WP @ 300 gm/acre at before flowering.
  • Spraying Propiconazole 25% EC @ 125 ml/acre at pod formation stage.

Soil Preparation for Potato Cultivation

12/10/2019Posted on

Soil Preparation for Potato Cultivation:-

  • A well pulverized seed bed is required for good tuberisation of potato crop.
  • Potato is taken as a Rabi Crop. Soon after the harvest of Kharif Crop, the field should be Ploughed once 20-25 cm. deep with soil turning plough.
  • Thereafter, two to three cross harrowing or four to five ploughings with local plough should be done.
  • One or two plankings are also needed to make the surface smooth and leveled.
  • Enough moisture is essential at the time of sowing.

Why & how to apply FYM in soil?

11/10/2019Posted on

  • Most of the arable lands across the country show low levels of organic carbon with deficiencies ranging from 11% to 76%.

  • FYM is a good source of organic carbon.

  • Soil organic carbon is the key factor of soil fertility by releasing the nutrients for plant growth, promotes the structure of the physical and biological health of the soil.
  • Farmyard manure is organic matter used as fertilizer in agriculture. Manures improve the fertility of adding organic matter and lots of nutrients, On average well-composted farmyard manure contains 0.5% N, 0.2 % P2O5and 0.5 % K2O.
  • They supply plant nutrients including micronutrients and increase their availability.
  • They improve soil physical properties like Water holding capacity, Porosity, etc.
  • Heat and CO2 control harmful fungus & insects in the soil. This CO2 & Heat are released due to the decomposition of FYM.
  • The nutrients are lost due to leaching by rainwater so 8 -10 Tones /acre well-rotted farmyard manure (FYM) should be spread uniformly on the unploughed soil.

Green house

11/10/2019Posted on

A greenhouse is a framed or an inflated structure covered with a transparent or translucent material in which crops could be grown under the condition of at least partially controlled environment and which is large enough to permit persons to work within it to carry out cultural operations.

Advantage of Greenhouse: 

  • Under the greenhouse one can grow crops under a controlled environment and throughout the year four to five crops can be grown due to the availability of required plant environmental conditions.
  • This helps in increased crop productivity and superior quality of products can be obtained.
  • Gadgets for efficient use of various inputs like water, fertilizer, seeds and plant protection chemicals can be well maintained in a greenhouse.
  • Pests and diseases can be effectively controlled in the growing enclosed area.
  • Pests and diseases can be effectively controlled in the growing enclosed area.
  • The percentage of germination of seeds is high in the greenhouse.
  • When the crops are not grown, drying and related operation of the harvested produce can be taken up utilizing the entrapped heat.
  • Greenhouses are suitable for automation of irrigation, application of other inputs and environmental control by using a computer and artificial intelligence techniques.

Importance of Zinc

10/10/2019Posted 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.

Importance of Iron in Crop Production

10/10/2019Posted on
  • Iron (Fe) is essential for crop growth and production. Iron is a component of many enzymes associated with energy transfer, nitrogen reduction, and fixation.
  • In high pH, soil iron turns into an unavailable form.
  • Young leaves are chlorotic in iron-deficient plants.
  • Pale yellow mottling starts at the base of the leaves and spreads upward along the midrib and outward along the veins.
  • Its deficiency can be corrected by spray @150-200g/acre ferrous sulfate till the chlorotic symptoms do not appear on young leaves.

Management of fruit fly in bitter gourd

07/10/2019Posted on
  • Collect and destroy infested fruits.
  • To prevent egg-laying, fly traps(pheromone trap) can be set up in the field with 1% Methyl Eugenol or Citronella oil or Vinegar or Dextrose or Acetic acid or Lactic acid.
  • Cover developing fruits with paper or polythene cover immediately after anthesis pollination.
  • Maize plants grown in rows at a distance of 8-10 cm in the field is effective as flies rest on such tall plants.
  • Deep plowing to expose hibernating stages.
  • spray dichlorvos 76% EC 250 to 500ml/acre or
  • Lambda Cyhalothrin 4.9%CS @ 200 ml/acre. or 
  • Profenofos 40%EC + Cypermethrin 4 %EC @ 400 ml/acre
