Supplementary Fertigation (પૂર્તિ ખાતર)

Supplementary Fertigation 

(પૂર્તિ ખાતર)

Supplementary fertigation is the fertilizer given during the growth of the crop after sowing. In order to give this, it is necessary to take into account the life span of the crop, type of soil, type of fertilizer and soil moisture conditions so as to get maximum crop production and maximum economic return.

Winter irrigated crops like wheat, chickpea, rye, tuber, garlic and onion, spice crops like cumin, sorghum, coriander and fenugreek are grown. In the chickpea crop, the rootstocks are bound to the roots in a month or so and provide nitrogen to the crop by stabilizing the nitrogen in the air. It is recommended to give only basic fertilizers in chickpeas under normal circumstances.

Wheat

Wheat is an important winter crop. For high yielding varieties of irrigated wheat, it is recommended to apply 150 kg nitrogen per hectare, 40 kg phosphorus and 20 kg potash per hectare in case of potassium deficiency based on chemical analysis of the soil. Out of the amount of these elements, all the phosphorus, potash and half the amount of nitrogen i.e. (20 kg) as the basic fertilizer should be applied at the time of sowing. Giving in depth. It is recommended to apply the remaining 20 kg nitrogen as fertilizer 15 to 21 days after sowing of wheat i.e. at the root stage after irrigation. This supplement will require 150 kg of urea or 200 kg of ammonium sulphate. Spraying of 5% solution of urea in wheat crop at the time of swallowing and germination improves production and quality. In addition, if the soil test is found to be deficient in micronutrients like zinc or iron and not given as a base fertilizer, the deficient element can be given by two sprays after flowering in the recommended quantity.

Raydo

20 kg nitrogen per hectare is recommended for Rayda crop. Out of this quantity 3 kg nitrogen should be given to Orin in fodder at the time of sowing as base fertilizer. It is recommended to apply the remaining 3 forts as nitrogen supplementary fertilizer at 30 days after sowing i.e. at the growth stage of the internode.

Onion

It is recommended to give a total of 5 kg nitrogen per hectare to the onion crop, out of which 20 kg nitrogen should be given at the time of planting and the remaining 5 kg nitrogen supplement should be given 30 days after planting.

Garlic

Garlic crop is recommended to apply 50 kg N per hectare. Apply half of this amount i.e. 3 kg nitrogen as base fertilizer at the time of sowing. While the remaining 3 kg nitrogen is recommended to be given 30 days after sowing.

Jiru and Isabgul

It is recommended to apply 20 kg N per hectare for cumin and sorghum crops. Out of this quantity 15 kg nitrogen should be given as base fertilizer at the time of sowing while the remaining 15 kg nitrogen should be given 30 days after sowing.

Coriander and fenugreek

Apply 20 kg nitrogen per hectare of coriander and fenugreek as recommended base fertilizer at the time of sowing. While remaining 20 kg nitrogen should be given 30 to 5 days after sowing.

It is important to use manure for complementary purposes. Different chemical fertilizers containing nitrogen are available in the market and also contain different amounts of nitrogen such as 3% in urea, 20.8% in ammonium sulphate, 4.0% in ammonium sulphate nitrate, 4.0% in calcium ammonium nitrogen (cans). Have. So buy and use a fertilizer that is cheaper in terms of the elements in the chemical fertilizer. Urea is currently the cheapest and most easily available fertilizer. However other fertilizers are expensive but should be used in certain special circumstances. Things to keep in mind when supplementing fertilizers

(1) After irrigating the supplementary fertilizers, 5 to 10 cm. Giving away and giving depth gives maximum benefit.

(2) If urea is given on the ground, nitrogen is released into the air.

(3) Use neem coated urea to increase the efficiency of nitrogenous fertilizer. (3) The efficiency of urea can also be increased by applying a layer of lemon oil.

(V) Nitrate fertilizers are applied in sandy soils.

(2) Complete fertilizers should be given only after weeding.

In this way, the recommended amount of fertilizer for each crop by the farmers is given by the right manure at the right time and in the right manner and if the things outlined in this article are taken into consideration, maximum yield and maximum economic benefit can be obtained.
