Farming in polyhouse will get many benefits, there are more benefits
-
In a polyhouse, plants can be grown in a controlled environment with less water, limited sunlight, and a minimum amount of pesticides.
-
In a polyhouse, plants can be grown under different conditions, which are impossible to cultivate in that particular climatic zone. For example, growing strawberries in the plains of India.
-
External climate does not affect the growth of crops
-
product quality improves.
-
It conserves 90% of water in vegetables, fruits and flowers, thereby increasing the shelf life of the produce
-
Polyhouse also provides a high concentration of Co2 to increase production to the maximum level, due to which polyhouse yield is much higher than open field cultivation.
-
Water is saved due to drip irrigation.
-
It can create the right environment for plants in any season.
-
With the help of polyhouse, crops can be protected from wind, rain, precipitation and other climatic factors.

Symptoms and control of downy mildew in cucumber crop
This is the most important disease of cucumbers, and this disease is caused by a fungus. Usually, its symptoms appear on the upper surface of the leaves. Initially, small yellow or orange spots appear on the leaves, and as the spots enlarge, they become brown with irregular margins. The white or light purple powder appears on the surface of the lower leaves of infected plants. The fruit is not affected by this disease, but it is less sweet in taste.
Control: To control it, grow resistant/tolerant varieties, avoid excessive overhead irrigation and irrigate the field late in the morning to dry leaves faster. If infestation is observed, spray Mirador (Azoxystrobin 23% SC) @ 200 ml per acre or Clutch (Metiram 55% + Pyraclostrobin 5% WG) @ 600 -700 gm per acre.

Harm and symptoms of lame fever disease in animals
One of the major diseases occurring in cattle is lameness fever. And if the treatment of lame fever in animals is not done at the right time, then the animals can die. Lame fever is known by many names like black quarter disease, Krishna Janga disease, lameness disease, Jaharbad disease, Ektanga disease, etc. Cows of a young age are more affected by this disease. Animals can die within 24 hours after the symptoms of lameness fever appear. The outbreak of this disease is more in the month of April to June.
Symptoms of lameness fever in cattle
-
The body temperature of animals increases.
-
Swelling occurs in the flesh of the legs and back of animals.
-
Due to pain in the leg, animals start walking with a limp.
-
Animals sit or lie down for a long time.
-
After some time the swelling cools down and the swollen part starts rotting.
-
On pressing the rotten place, there is a sound of char-char.
Preventive measures against lame fever
-
Every year all animals from 4 months to 3 years should get a lame fever vaccine.
-
To protect animals from lameness fever, do regular cleaning of the animal house.
-
Keep disease-affected animals separate from healthy animals.

Measures to protect moong crop from sucking insect
Moong has a special place in pulse crops. But many times due to the outbreak of sucking insects, there is a huge loss to the moong crop.
Thrips: These insects harm the crop by sucking the sap from the leaves. Affected leaves tend to curl upwards. As the infestation increases, the plants turn yellow and become weak and the growth of the plants stops.
Control: To control infestation as soon as an infestation is observed spray, Lamnova (Lambda-cyhalothrin 4.9% SC) @ 250 ml per acre or Profenova Super (Profenofos 40% + Cypermethrin 4 % EC) @ 400 ml per acre in 150-200 litres of water.
Aphid: This insect lives in the group and due to this it causes more damage to the crop in less time. These insects suck the sap of tender stems, leaves, flowers and pods of plants. As a result, less flowers emerge in the plants and grains are not formed in the pods.
Control: To control aphids, use 5-6 yellow sticky traps per acre in the field. Along with this, spray Thianova 25 (Thiamethoxam 25 %WG) @ 100 gm per acre, and Novamaxx (Gibberellic Acid 0.001%) @ 300 ml per acre in 150-200 litres of water.

Know the importance of potash in the crop
Due to the lack of nutrients in the soil, the proper development of plants is not possible. That’s why the use of manure and fertilizers should be balanced so that the crop can get all kinds of essential nutrients in sufficient quantities.
Potash is an essential nutrient
-
Potash is necessary for the growth and development of plants.
-
Potash helps in protecting the crops from weather adversities like drought, hailstorms and insect-disease etc.
-
Potash protects crops from uprooting by proper growth of roots. With the use of potash, the cell walls of the plants become thick and the stem grows in the layers of the cell, as a result of which the crop is protected from falling.
-
The crops which get full amounts of potassium require relatively less water to give the desired yield, the use of this light potassium improves the water use efficiency of the crop.
-
Potash is the most important element which enhances the quality of crops.

Earthworm composting method for natural farming
Earthworms are considered a friend of farmers. It makes a significant contribution in the form of land reform. Earthworm eats garbage/soil equal to their own weight daily and makes it granular fertilizer like soil. A species called ‘Asafoetida’ is suitable for making manure.
During the process of decomposition of raw cow dung, heat is generated from it, which is harmful to earthworms. To avoid this loss, it is necessary to rot the waste generated in the field separately for 15 to 20 days. Along with this, it should be kept moist for 10 days so that the heat released at the time of dissolution ends. After its heat is released, it can be used as food for earthworms in vermi beds.
Method of preparation of vermi bed:
It is most important to have a shady place to make earthworm compost. The length of the vermi bed should be 20 feet and the width should be 2.5 to 4 feet. While making the bed, first of all, pieces of brick (3-4 inches) are placed at the bottom of the pit, on the above of it place a layer of sand (2 inches) and soil (3 inches). so that earthworms can remain safe inside the vermi bed.
After this, 6 to 12 inches of old rotten garbage is put on it for earthworm food. Stop watering the bed after 40 to 50 days when light granular manure appears on the top. When the top compost dries, earthworms will slowly go inside, in this way the top compost can be removed. In the vacated bed, the process of composting continues again by using the second waste which is made for the food of earthworms. In this way, about 500 to 600 kg of vermicompost can be obtained from one bed.

Sample Collection Method for Soil Testing
The most important thing for soil testing is to collect the right soil sample. For sampling, note that before sampling, the growth of the crop taken in the field has been the same, and the same fertilizers have been used in them.
Sample Collection Method-
-
Make a mark at 10-15 places by moving in a zig-zag manner in the field where the sample is to be taken so that all parts of the field can be included in it.
-
Remove grass, straw, garbage etc. from the upper surface at the selected places.
-
In all these places dig the pit 15 cm (6-9 inch) deep “V” shape. After cleaning the pit, 2 cm from top to bottom on one side with the hoof, Take out the layer of thick soil and put it in a clean bucket or tray.
-
Mix the entire soil collected by hand and make a round heap by putting it on a clean cloth. Divide the pile made into four equal parts and remove two piles. Now mix the soil of the remaining two heaps well again and make round heaps. Repeat this process until 500 grams of soil are left.
-
Place the dry soil sample in a clean plastic bag and put it in a cloth bag. Tie a notice sheet with the sample on which all the information is written inside a plastic bag and outside a cloth bag.
