Mazzard is the most popular cherry rootstock grown in North America. It is generally more vigorous than Mahaleb, especially in poorer soils. Performs in deep soils with good drainage. This rootstock is somewhat dwarfing, cold hardy and precocious.
It is a robust and determined cherry tree that offers high yields of tiny, delicious cherries. This variety is extremely disease resistant and works great as a rootstock for grafting other varieties.

Welsh and Grimbell 1947 first reported male sterility in carrots.
Cytoplasmic male sterility in carrots can occur in two morphologically distinct phenotypes. CMS system has been established for the first time in Asiatic carrot germplasm in India at IARI. CMS was introduced into carrot breeding materials and provides a very efficient tool for mass-scale pollination control.

Petha is made from Ash gourd.
Ash gourds, commonly referred to as white pumpkins, are a vegetable with a pale-green exterior and white, heavily-seeded, savory inside that is used to make petha. The gourd is sliced into bite-sized pieces and then cured for a few hours in a solution of lime. They boil the gourd pieces until they are soft after removing them from the lime solution, and then they soak them in a flavorful syrup. The final candy has a sugar-crisp exterior and an almost moist, sticky interior with a chewy, crystalline texture.

Cauliflower is infected by Diamond Back Moth, It is one of the serious pests of cauliflower in India and worldwide. The greyish brown moth has typical white patches, which form a diamond-like appearance on the wings while in rest. It feeds on leaves and makes bite holes, causing excessive defoliation, mostly on the growing part i.e primordial.
Chilli thrips are caused by Scirtothrips dorsalis. The infected leaves develop crinkles and curl upwards, Elongated petiole, Buds become brittle and dropdown. Early stage, infestation leads to stunted growth and flower production and fruit sets are arrested.
Okra shoot and fruit borer are considered to be the major insect pest of the crop, which interferes with its economic production in almost all okra-growing countries. The larva bores into tender terminal shoots in the vegetative stage and flower buds, flowers and young fruits in the fruit formation stage.
Potato is infected by cutworms. The caterpillars cause crop damage. They feed at night on young shoots or underground tubers. After tuber formation, they bore and nibble into the tubers affecting both tuber yield and market value.

Pusa Early Dwarf, Pusa Ruby and Angurlata are improved varieties of Tomato.
Pusa Early Dwarf is typically dwarf, 50 - 55 cm in height with compact fruiting, slightly flat in shape, medium large, uniformly red, ribbed, obscure furrow, 5 - 6 locules, 30 - 40 fruits per plant. Maturity 55 - 60 days after transplanting. Suitable for the rainy season in plains and March sowing in Hills.
Pusa Ruby is an Early maturity (60 - 65 days) variety suitable for autumn, winter & spring summer. Fruits are flattish round, small to medium, 4 - 5 locules and slightly acidic. 25 - 30 fruits per plant. Good for juice & ketchup.
Angurlata is a vine variety of tomatoes.

Floating gardening is very much common in Jammu and Kashmir.
A planting on soil buoyed up (as on the surface of a lake) by rafts of interlaced branches or other floating support is found chiefly in the Mexico City area and parts of Kashmir.
Islands or floating gardens on the Dal Lake in Kashmir are formed from the weeds, after collecting them from the lake itself. Such weeds mostly consist of Typha augustata and Phragmites communis which are in the Kashmiri language known as Pech and Nargasa, respectively.

Broad Bean is used for making wine. Any legume pods can be used to make wine, whereas broad beans are grown for wine processing as they have heavy pods.
In addition to adding a slightly more rounded flavour to the wine, their sweet sugars should prevent the pod’s overall essence from being lost.

The seed requirement for carrot cultivation is 5 - 6 kg/ha.
Carrot is a cool season crop and will develop a good colour when grown at 15°C to 20°C. The crop needs deep loose loamy soil. It requires a pH ranging from 6.0 to 7.0 for higher production. Carrot can be grown throughout the year at an elevation above 1500 metres with assured irrigation.

“Bulletin of vegetable crop research” is published in Poland.
The Vegetable Crops Research Bulletin is a peer-reviewed journal, that publishes mainly original research papers. The journal examines various aspects of research and is devoted to the publication of papers dealing with the following subjects: biotechnology, plant breeding, crop cultivation outdoors and under covers, soil management and plant nutrition, etc.

Universal Donor variety of Cherry is all the given options that are, Vega, Stella and Vista.
These are good pollinizers to plant with any variety. Pollination is an important consideration in cherries. Many modern varieties are self-fertile and are universal pollen donors. There is strong anecdotal evidence to suggest that even self-fertile cherries give greater yields per hectare when planted in blocks of 3 rows with other pollen donors.
