Irrigation management in watermelon crop

Irrigation management in watermelon crop
  • Watermelon is a more water-consuming crop, but water logging is harmful. Overwatering at the bottom of the plant can lead to root rot and fruit rot.

  • Watermelon is cultivated especially in the Zaid season, so the interval of irrigation is very important in this.

  • Watermelon should be irrigated mainly at an interval of 3-5 days, that is, sufficient moisture should be maintained in the soil.

  • Soil moisture stress during the pre-flowering, flowering, and fruit development stage drastically reduce the yield.

  • Irrigation should be stopped during ripening as it adversely affects fruit quality and promotes fruit cracking.

  • Non-edible cakes- it is not edible for animals. They are used as manure in the field, like castor, mahua, neem, karanj etc. It also acts as a pesticide in the crop.

  • Nitrogen is found in higher quantities in oil cakes than cow dung manure and vermicompost, as well as phosphorus and potash are also found in oil cakes.

  • The number of nutrients available in different oil cakes-

Know the method of application of oilcake in crops- 

  • Oil cake manure comes in the category of concentrated organic manure, it can be used in the field both pre and post sowing.

  • Method of application of oil cakes pre-sowing – Apart from Mahua cake, the powder of all cakes should be used in the field 10-15 days before sowing.

  • Mahua cake decomposes late, so it should be used in the field 2 months before sowing. A chemical called saponin is found in it, due to the presence of which it is a good manure for paddy crops.

  • The cakes should be scattered in the field and mixed in the soil after ploughing lightly.

  • Method of application of cakes post sowing – After germination, use powdered oil cake near the plant. 

  • Oilseeds can be used while earthing up in tuber root crops. 

  • Keep in mind that after putting the cakes in the field, it is very important to have enough moisture in the soil for their decomposition.

Neem cake and its uses

Neem cake and its uses
  • Neem cake is an organic fertilizer. It contains nitrogen, phosphorus, potassium, zinc, copper, sulfur, calcium, magnesium, iron and other micronutrients.

  • The use of Neem cake has dual benefits, it acts as a fertilizer as well as a pesticide.

  • Neem cake contains 8-10% neem oil which we use as an organic pesticide. When we use chemical insecticide continuously, then the resistance comes in the insect against that chemical and the next time the pest becomes stronger, but if we use neem oil cake as a pesticide, then it affects the insect hormone so that they are unable to grow any further and get destroyed.

  • The use of neem cake retains moisture in the soil and gives shine to the leaves and stems of plants.

  • The use of Neem cake increases the level of amino acids in plants. Which also increases the level of chlorophyll, due to which the plants appear green.

  • The use of neem cake also prevents fungal diseases, harmful bacteria and ants.

  • If flowers are not coming in plants or flowers are dropping or the size of the fruits is small, then all these problems go away with the use of neem cake.
