Plants may be attacked at any stage; young plants can suddenly dry up or older plants might develop a pale green color accompanied by wilting of lower leaves. Infected plants first develop a dull green color, eventually wilt and turn straw-color. Symptoms often appear on one section of the plant. This is typically followed by broad wilting and the death of the entire plant. Plants may wilt in the middle of the day when the temperature is high in the early stages of infection and appear to recover at night. Some plants may not display symptoms of infection until they reach flowering, at which point they collapse. When the stem is severed, the vascular tissues may develop a brown tint or streaking.
Scientific Farming
What are the advantages of zero till sowing of wheat ?
When compared to traditional wheat planting, zero till sowing might save 68 percent of time and 85 percent of the cost of operation. The zero-till drill was more efficient since the crop could be sown over a larger area in a shorter amount of time when moisture was available. The cost of a zero till drill is between Rs.45,000 and Rs.60,000. Two days earlier than usual, with more uniform germination and a better plant stand.
What is DSR ?
DSR is direct seeded rice. The nursery for transplantation is not raised in direct seeded rice (DSR) farming. In the event of a monsoon delay or a water constraint, DSR allows the farmer to direct sow paddy with a suitable duration variety to fit into the remaining season. This enables for the seeding of rabi wheat in a timely manner. When compared to transplanted flooded rice, direct sown rice uses less water. When compared to transplanted rice, the energy requirement for pumping irrigation water is also lower, and savings can be significantly higher during periods of low rainfall.
What is pre-drying?
The stage of the post-harvest system during which the harvested product is dried in order to undergo the next operation of threshing in the best possible conditions is referred to as “pre-drying.”The cut areas of the plant may include too much green plant debris during harvest time, and all of the grains may not have reached a uniform degree of maturity or have a moisture level that is too high. This necessitates pre-drying.
Given the importance of vegetables, the concept of growing our own vegetables in our backyards utilising abundant fresh water and a kitchen has evolved. This will only aid in the successful creation of our own vegetables requirements.
Cultivation in a small area facilitates pest and disease control measures by removing infected areas and avoiding the use of pesticides. This is a safe procedure that does not result in hazardous pesticide residues in the vegetables grown.
What are the uses of silver hydrogen peroxide?
Silver hydrogen peroxide provides high efficacy in killing of microorganisms in all possible media applications of air, water, surface, and soil. It works as an antibiotic, fungicide, virucide, amoebicide, and algaecide against a wide variety of microorganisms. The hazardous pesticidal residues are removed after harvesting using silver hydrogen peroxide.
Powdery mildew, downy mildew, botrytis blight, anthracnose, bacterial leaf spots and cankers, as well as pests such as worms and mites, are all well-known among farmers, and using silver hydrogen peroxide for a comprehensive field sanitation eliminates them.
What is chawki rearing in sericulture ?
Chawki means the first two stages of silkworm rearing. If the chawki worms are not reared properly, the later stages will result in crop losses. Hence, chawki is the most crucial period of silkworm rearing that demands optimum temperature and humidity, hygienic conditions, quality tender leaf, good rearing facilities and above all technical skills.
What is APEDA ?
APEDA or Agriculture and processed food production export Development Authority is in charge of promoting the export of fresh fruits and vegetables, processed foods, livestock products, and cereals. It serves as a vital link between farmers, warehouses, packers, exporters, surface transportation, ports, railways, airlines, and everyone else involved in the export trade, as well as the international market. It provides services to farmers and exporters from several states in the country, either directly or indirectly. It helps agricultural and processed food producers connect with exporters on worldwide markets by bridging the gap between them.
What is floriculture?
The study of growing and marketing flowers and foliage plants is known as floriculture or flower farming. Floriculture is the cultivation of flowering and attractive plants for direct sale or as raw materials in the cosmetics and perfume industries, as well as in the pharmaceutical industry. Seeds, cuttings, budding, and grafting are also used to produce planting materials. Floriculture, in its simplest form, is the art and science of growing flowers to perfection. Floriculturists are professionals who work in this industry.
How short term storage of button mushroom is done?
Button mushroom have a short shelf life. Cut at the soil line, harvested mushrooms are washed in a solution of 5g. KMS in 10L. water to remove soil particles and induce whitening. These are wrapped in perforated plastic bags with roughly 250-500 g of mushrooms apiece after eliminating extra water. For a brief period of 3-4 days, they can be stored in polythene bags at 4-50 C.
