Mastitis is a condition in which the mammary gland becomes inflamed. Physical, chemical, and microbiological changes occur in milk, while physical and pathological changes occur in mammary glandular tissue. Infected milk changes colour, consistency, and has a higher concentration of leucocytes.
What is in-situ moisture conservation?
In-situ moisture conservation is done by constructing small beds where moisture is conserved consistently in the field. It also helps to decrease water runoff and soil erosion. The moisture saved thereby decreases water stress throughout the key growth stage. This results in a guaranteed yield of rainfed crops such as Jowar and Bajra.
What is the use of corcyra moth collector ?
Corcyra moth collector is used in order to mass-produce biological control agents. It is used to collect corcyra moths with the least amount of health risk. As collecting time is minimised, productivity rises. This type of collectors ensures that the moth is collected without being harmed.
Why vaccum packing of banana is done ?
After harvesting, bananas ripen in three to five days. Ripening occurs during long-distance transportation and export, resulting in significant post-harvest losses. Vacuum packing is one of the methods for delaying the ripening of fruits, in which mature banana hands are bagged and kept from coming into touch with air/oxygen. Bananas can be vacuum packed using a basic vacuum packaging device. This can postpone ripening for up to 21 days, and ripening can be completed within one week of opening the package.
What causes blackening of rose petals?
Low temperature and high anthocyanin content causes blackening of rose petals. Anthocyanin buildup in Baccara rose petals is caused by GA3 treatment. At low temperatures (20°C during the day and 4°C at night), this effect was more evident than at higher temperatures (30°C during the day and 20°C at night).
What is blind wood of rose ?
A greenhouse rose’s regular flowering stalk has fully grown sepals, petals, and reproductive organs. The apical end of the stem failing to form a flower is a regular occurrence. Blind wood refers to these types of shoots. The reproductive components are absent or aborted, while the sepals and petals are there. Blind wood is usually short and thin, but when it grows at the top of the plant, it can grow to be rather long and thick. Low temperatures, insufficient light, chemical residues, insects, pests, fungal infections, and other factors can all contribute to this.
How plastic films helps in suppressing weed growth ?
Black plastic film does not allow the sunlight to pass through on to the soil. Photosynthesis does not take place in the absence of sunlight below black film. Hence, it arrests weed growth.
What are the advantages of plastic mulching ?
Plastic mulching is completely impermeable to water. It conserves moisture by preventing direct evaporation of moisture from soil. By evaporation suppression, it prevents the rise of water containing salts. Mulch can facilitate fertilizer placement and reduce the loss of plant nutrient through leaching. Mulches can also provide a barrier to soil pathogens. Opaque mulches prevent germination of annual weeds from receiving light. Reflective mulches will repel certain insects.
How post harvest handling is done in hybrid rose ?
After harvesting, immediately place roses in a bucket of water inside the polyhouse and transport to cold storage (2-4°C). The length of time depends on the roses’ variety and quality. The length of the flowers is used to classify them. It ranges in length from 40 to 70 cm, depending on the variety, and is packaged in tens or twelves per bunch.
What is paired row technique ?
Paired row technique is growing crop on both side of the furrow. This is done by increasing the ridge spacing . Thus , a single furrow can be used for irrigating two rows. This method of irrigation has been experimented for crops like greengram, blackgram, groundnut and sunflower. The results showed that there was saving of about 20 % irrigation water and 15 % increase in crop yields.
