Importance of Potash in Crops

11/09/2021 Friday September 10th, 2021

Potash is an essential nutrient for good crop production
A balanced amount of potash increases the immunity towards adverse conditions in the crop such as pests, diseases, lack of nutrition, etc.
the brightness of seeds, weight gain, and the quality of yield also increases.
Potash helps in good root development and strong stem growth in the crop, which results in its good grip on the soil.
A balanced amount of potash develops soil water holding capacity
Potash is an enhancer of crop yield and quality.
Potash deficiency affects crop growth.
The colour of the leaves becomes darker
Due to potash deficiency, the edges of the old leaf of the crop turns yellow and the tissue of the leaf dies, resulting in the drying of the leaves.

Improved varieties of potato and method of preparation of the field

09/09/2021 Thursday September 9th, 2021

Solanum Tuberosum: This is a commonly cultivated species of potato, its plants are short with thick stems and leaves that are large and relatively long.
Kufri Jyoti, Kufri Muthu, Kufri Swarna, Kufri Malar, Kufri Soga, Kufri Anand, Kufri Miracle, Kufri Alankar, Chipsona and Kufri Giriraj are commonly cultivated.
Field preparation- A well-drained soil or seedbed is required for good tuberization of the potato crop. Potato is mainly grown as a Rabi crop. Immediately after harvesting the Kharif crop, plough the field once, 20-25 cm deep using soil turning plough. Thereafter, two to three times of cross harrowing or four to five ploughings with a cultivator are necessary to make the surface smooth and even. It is necessary to have sufficient moisture in the field at the time of sowing.
Potatoes can be sown by the following methods, out of which the popular method is to prepare the ridge and furrow and sow it.
If the carbon content of the soil is low, four metric tons per acre of well-rotted manure should be used during land preparation, this amount should be given fifteen days before planting. Potato plants require a lot of nutrients.

How to recognize Purple blotch disease in onion, know how to treat it

07/09/2021 Tuesday September 7th, 2021

Purple blotch is a soil-borne disease. Symptoms of this disease are small, sunken, white spots on onion leaves and stalks with purple centres. Its lesions surround the leaves/stalks and can cause them to drop. Infected plants fail to develop bulbs.

Prevention Measures:

Use healthy seeds for sowing.
Adopt crop rotation of 2-3 years and make a proper drainage system.
Use recommended doses of fertilizers containing nitrogen and phosphorous.
Before sowing, treat the seeds in hot water for 20 minutes at 50 °C and select resistant varieties.

Soil Treatment: To protect against this disease, spread Trichoderma viridi 500 gm in soil with 4 to 5 tonnes of well-decomposed cow dung per acre evenly before sowing. Re-use Trichoderma Viridi 500g/acre after 30 days.

Chemical Control:

Seed Treatment: Before sowing, treat the seeds with Carmanova 2.5 gm/kg seed solution.

Preventive measures at the onset of disease symptoms: Spray Hexaconazole 5% SC (Novacone), @ 400 ml + Silicomax (sticker) @ 50 ml per acre in 200 litres of water or Kitazin 48 when the initial symptoms of the disease appear. Spray % EC @ 200 ml + Silicomax (sticker), @ 50 ml per acre in 200 liters of water or spray Pseudomonas fluorescens (Monas curb @ 250 g @ 250 g in 200 liters of water) for biological control.

Importance of soil treatment before sowing of Rabi crops

07/09/2021 Tuesday September 7th, 2021

In any season soil treatment is very necessary before sowing the crop.
Soil fertility and nutrient management are very important factors for good crop yield and disease-free crops which have a direct impact on crop yield and quality.
After Kharif season, before the sowing of rabi crops, there is too much moisture left in the soil which causes a lot of infestation of fungal diseases and insect-borne diseases.
Soil treatment is done with fungicides and insecticides for the prevention of fungal disease and insect-borne diseases.
Soil treatment is also very important to overcome the deficiency of nutrients in the soil,
Soil treatment improves soil texture and increases production.

Management of Cucumber mosaic viral diseases in cucurbits

05/09/2021 Monday September 25th, 2023

Mosaic viral disease in cucurbits is generally spread by whitefly and aphid.
In this disease, irregular light, dark green and yellow stripes or spots appear on the leaves.
The leaves then curl, shrink and the veins of the leaves turn dark green or light yellow.
The plant remains small and the fruits/ flowers seem to grow less or shed.
Infected fruits are often deformed and discoloured, remain small and produce negligible seeds when severely infected.
Whitefly and aphid should be controlled to prevent this disease.
Spray Acetamiprid 20% SP @ 100 gm or Acephate 75 %SP @ 300 gm or Bifenthrin 10% EC @ 300 ml or Diphanthiuron 50%WP @ 250 gm/acre at 10-15 days interval to protect the crop from such pests.
For biological control, spray Metarhizium @ 1 kg/acre or Bavaria bassiana @ 250 gm /acre.

Why do onion plants show tip burn problems?

02/09/2021 Thursday September 2nd, 2021

Onion is an important commercial crop grown in India. The problem of tip burn in onion crops mainly appears at the time of crop development when the crop is close to the mature stage then the process of tip burning can be natural, but in young plants, tip burn can happen due to many reasons. Possible causes include a lack of important nutrients in the soil, fungal infections, or sucking insects such as thrips, etc.
Heavy wind, excessive sunlight, excess salt in the soil and other environmental factors can cause onion tips to burn. Given all the possible causes of leaves with brown, dry tips, it can be hard to pinpoint the origin of the problem. Remember, if you have taken care of all of the above problems, It could be fungal related.
To remedy the problem of tip burn, keep all the above things in mind, spray 200 ml per acre of neem oil 10000 ppm to protect against sucking insect leaf minors, thrips, etc.
Spray Fipronil 5% SC 400 ml or Thiamethoxam 25% WG 100 gm + Tebuconazole 10% + Sulphur(s) 65% WG 500 gm + Gibberellic Acid 0.001% 300 ml per acre.

Symptoms of phosphorus deficiency in cotton

01/09/2021 Thursday September 2nd, 2021

Phosphorus deficiency symptoms in cotton do not cause any visible decline in most other nutrients.
Its symptoms first appear on small and very dark green leaves, whose leaves turn light purple or brown.
This causes stunted growth in plants.
Due to phosphorus deficiency, diminishing growth and development of the roots is observed, which sometimes can cause the roots to dry up.
Due to excessive deficiency of phosphorus, the stem turns dark yellow, and the formation of fruits and seeds is immature.

Damping-off disease will cause damage in onion nursery

31/08/2021 Tuesday August 31st, 2021

High soil moisture and moderate temperature along with high humidity, especially in the rainy season leads to the development of this disease.
Pre-emergence damping off results in seed and seedling rot before emerging from the soil.
Post-emergence damping-off results in pathogens attacking the collar region of seedlings on the surface of the soil.
The collar portion rots and ultimately the seedling collapses and dies.
Healthy seeds should be selected before sowing.
Spray of CARBENDAZIM 12% + MANCOZEB 63% WP@ 30 gram /pump or THIOPHANATE METHYL 70% W/W @ 30 gm/Pump or MANCOZEB 64%+ METALAXYL 8% WP @ 60 gram/pump.

This American pest causes great damage to tomato crop

31/08/2021 Tuesday August 31st, 2021

The American pinworm [Tuta absoluta] is one of the major and important pests of tomato. Tuta absoluta is a serious pest that is highly harmful in all stages of its life cycle. IPM practices can be adopted to avoid and manage the pest throughout its life cycle. The crop losses are as high as 60 to 100% due to the infestation by Tuta absoluta. Its infection is visible on buds, leaves and stems, flowers and fruits, on which a fine powdery layer with black spots appears.
It burrows in the leaves and eats the lamina of the leaves, affecting the photosynthetic activity, as well as making them inedible by piercing the fruits.
For its management follow crop rotation with non-solanaceous crops (preferably cruciferous crops).
Infested leaves need to be removed before the caterpillar inside the leaf is able to pupate and become an egg-laying adult moth.
The use of pheromone traps is beneficial.
For Chemical Control Spray Cyantraniliprole 10.26 % Od @ 240 ml + Neem oil 10000 ppm @ 200 ml or Quinalphos 25% Ec 400 ml + Abamectin 1.9% Ec 150 ml + Neem oil 10000 ppm @ 200 ml or Lambda Cyhalothrin 5% Ec + Neem oil 10000 ppm @ 200 ml per acre.
