Nutrient Management in Wheat

02/10/2018

Nutrient Management in Wheat:- Nutrients play an important role in the wheat production. Well rotted farmyard manure (FYM) or compost should be applied at the rate of 15 to 20 tons/ha. after every two years. The FYM and compost will keep the soil physical properties in good condition-

Apply well rotten FYM compost 15-20 ton per hac.in every 2 year interval.
Use 88 kg Urea, 160 Kg SSP and 40 kg MOP per Acre.
Apply urea in below three doses.

44 kg quantity during seed sowing.
22 kg during the first irrigation.
Remain 22 kg dose during second irrigation.

If the full quantity of phosphorus is added in Kharif season, then add half the amount of phosphorus in Rabi.
When you have minimum or two irrigation may be used 175:250:35-40 Kg/hac. quantity of Urea, SSP and MOP.
Use full quantity of NPK at a time of basal dose on unirregated condition.

If wheat sowing are done in mid-December, then 25% of the nitrogen should be reduced.

Phosphorus Deficiency in Cotton

18/07/2018

Phosphorus Deficiency in Cotton:-

Leaves of Phosphorus deficient plants remain dark green in colour with reduced leaf size. The deficiency symptom is first reflected in the lower or older leaves of cotton plant. The deepening of the green colour of the leaves progresses upward towards to the growing point to the extent phosphorus is deficient, suggesting that the nutrient moves to younger tissues as the supply diminishes. An extreme deficiency of phosphorus not only reduces the plant size, but also suffers from lack of secondary branches and reduction in boll number. It also leads to delay in blooming, fruiting and maturity of the bolls.

Younger Leaves show more dark green appearance. Older leaves become small in size and developed purple and red pigmentation.

Control:- Spray 12:61:00 or 00:52:34 @ 100 gm per pump.

Nitrogen deficiency in Cotton

12/07/2018

Nitrogen deficiency in Cotton:-

A pale yellowish green colour, coupled with reduction in leaf size is the most striking symptom of nitrogen deficiency in cotton. Eventually, the cells become disorganised accompanied by development of red pigments called anthocyanins. Nitrogen deficient plant is also characterized with little vegetative growth, lack of vigour coupled with stunted growth.

Control:- Spray 19:19:19 @ 100 gm per pump.

Nutrient management in sponge gourd and ridge gourd

24/02/2018

Nutrient management in sponge gourd and ridge gourd:-

About 20-25 t/ha of FYM should be applied at the time of field preparation.
75 kg Urea, 200 kg single super phosphate and 80 kg murate of potash per hectare is applied at the time of last ploughing.
Another 75 kg urea should be top dressed in two split doses one at 8-10 leaf stage and second at flowering stage.

Importance of Magnesium in Plants

27/12/2017

Magnesium (Mg), along with calcium and sulphur, is one of the three secondary nutrients required by plants for normal, healthy growth. Don’t be confused by the term “secondary” as it refers to the quantity and not the importance of a nutrient. A lack of a secondary nutrient is just as detrimental to plant growth as a deficiency of any one of the three primary nutrients (nitrogen, phosphorus and potassium) or a deficiency of micronutrients (iron, manganese, boron, zinc, copper and molybdenum). Furthermore, in some plants, the tissue concentration of magnesium is comparable to that of phosphorus, a primary nutrient.

Function of magnesium

Many enzymes in plant cells require magnesium in order to perform properly. However, the most important role of magnesium is as the central atom in the chlorophyll molecule. Chlorophyll is the pigment that gives plants their green colour and carries out the process of photosynthesis. It also aids in the activation of many plant enzymes needed for growth and contributes to protein synthesis.

Role of Potassium In Plant Growth

16/12/2017

Potassium (K) essentially plays a major role in plant physiological processes. Therefore, it is required in large amounts for proper growth and reproduction in plants. It is considered vital after nitrogen as far as nutrients needed by plants is concerned. It is also termed “the quality nutrient” for its contributing factor in a number of biological and chemical processes in plants. Potassium has many different roles in plants:

In Photosynthesis, potassium regulates the opening and closing of stomata, and therefore regulates CO2 uptake.
Potassium triggers activation of enzymes and is essential for production of Adenosine Triphosphate (ATP). ATP is an important energy source for many chemical processes taking place in plant issues.
Potassium plays a major role in the regulation of water in plants (osmo-regulation). Both uptake of water through plant roots and its loss through the stomata are affected by potassium.
Known to improve drought resistance.
Protein and starch synthesis in plants require potassium as well. Potassium is essential at almost every step of the protein synthesis. In starch synthesis, the enzyme responsible for the process is activated by potassium.
Activation of enzymes – potassium has an important role in the activation of many growth related enzymes in plants.

Role of Phosphorus in Plants

14/12/2017

Phosphorus (P) is essential for all living organisms. Plants must have phosphorus for normal growth and maturity. Phosphorus plays a role in photosynthesis, respiration, energy storage and transfer, cell division, cell enlargement and several other processes in plants. Phosphorus is a vital component of DNA, the genetic “memory unit” of all living things. Phosphorus is a vital component of ATP, the “energy unit” of plants. Thus, phosphorus is essential for the general health and vigour of all plants. Some specific growth factors that have been associated with phosphorus are:

Stimulated root development
Increased stalk and stem strength
Improved flower formation and seed production
More uniform and earlier crop maturity
Increased nitrogen N-fixing capacity of legumes
Improvements in crop quality
Increased resistance to plant diseases
Supports development throughout entire life cycle
