Field preparation and soil treatment in water melon before sowing
  • The land should be properly prepared by ploughing  according to the need and it is advisable to make small beds simultaneously. 
  • In heavy soils, seeds should be sown without a lump. The sandy soil does not require much tillage. 3-4 ploughing  is sufficient. 
  • Watermelon requires fertilizer. For soil treatment, it should be done by using a soil samridhi kit before sowing. 
  • For this, mix 50 -100 kg FYM or cow dung with compost or field soil, and broadcast it on an empty field before sowing.
  • DAP @ 50 kg / acre + SSP @ 75 kg / acre + Potash @ 75 kg / acre broadcast at the time of sowing.

Identification and control of white fly in potato crop

 

  • Symptoms of  Whitefly:- This pest causes a lot of damage in potato crops in both the stages of its life cycle i.e. nymph and adult.
  • They suck the cell sap out of cotton plant leaves and inhibit plant growth. These insects are also the cause for the secretion known as a sooty mold developed on the plant.
  • Potato crops can get completely infected during high infestation and even if the crop is fully developed, there is a chance of infestation of this pest which can cause the leaves of this crop to dry up and fall.
  • Management: – For the prevention of this pest, Diafenthiuron 50% SP @ 250 gram/acre or Flonicamid 50% WG @ 60 ml/acre or acetampyrid 20% SP @ 100 gram/acre or Pyriproxyfen 10% + biphenanthrene 10% EC 250 ml/acre

  • Thus it is very important to manage nutrition in this stage.
  • Due to the changing weather and nutrients deficiency in the crop, there is a problem of flower drop in the pea crop.
  • And excessive flower drop greatly affects fruit production in the pea crop.
  • Use Micro-nutrients @ 250gram/acre. 
  • To prevent flower drop,use Homobrassinolide @ 100 ml/acre or Paclobutrazol 40% SC @ 30 ml/acre.

Temperature control measures for good crop production

Temperature control measures for good crop production

Irrigation of fields is crucial: – Whenever there is a possibility of low temperature or frost warning has been given from the weather forecast department, light irrigation should be provided to the crop. The temperature will not fall below 0° C and crops can be protected from the loss due to lower temperature as Irrigation increases the temperature by 0.5 – 2° C.

Cover the plant: – The nursery is in the most vulnerable stage in low temperature. In nursery it is advisable to cover the plants with plastic sheets at night. By doing so, the plastic causes the temperature inside to increase by 2-3 degree celsius. Straw can also be used instead of polyethylene whose surface temperature does not reach the deposition point. While covering the plants, keep in mind that the south eastern part of the plants remain open, so that the plants get sunlight in the morning and afternoon.

Windbreakers: – These breakers reduce the intensity of cold waves and protect them from crop damage. For this, such crops should be sown around the field, so that the wind is controlled to some extent, for e.g. sowing maize in gram fields. To protect the plants from frost, they should be covered except in the direction of sunlight using straw or any other object.

Smoke near the field: – To control temperature, you can create smoke in your field, so that the temperature does not fall to the deposition point and crops can be protected from damage.

Nutritional management measures while tubers formation in the onion crop

Nutritional management measures while tubers formation in the onion crop
  • Until three leaves do not emerge after germination, the crop grows slowly above the ground and in the soil.
  • Once the 3 leaves emerge, the growth of the crop accelerates. This development takes place within the soil.
  • Plants produce more leaves to increase photosynthetic activity and store the materials needed to make bulbs.
  • Nutritional management in plants at this stage is important for bulb formation, crop development, and the beginning of final yield.
  • Presently spray Paclobutrazol @ 40% SC @ 30 ml/acre as spray
  • Use Calcium Nitrate @ 10 kg/acre + Potash @ 25 kg/acre as soil treatment.

  • Fertilizer management is done in three stages in wheat crop 1. at the time of sowing 2. Management in 20 -30 days of sowing 3. Fertilizer management in 50 -60 days of sowing
  • Fertilizer management at the time of sowing improves germination of wheat crop and provides uniform growth to the plant.
  • The  Management in 20 -30 days of sowing improves good root growth and development of tillers . 
  • By managing fertilizer in 50-60 days of sowing, the earhead emerges well and milk fills well in the grains and the production of grains is very good.
