Zero energy cool chamber operates on the principles of Evaporative cooling.
Zero energy cool chamber is an on-farm rural-oriented storage structure that operates on the principle of evaporative cooling was developed at IARI, New Delhi, using locally available raw materials such as bricks, sand, bamboo, dry grass, jute cloth, etc.
The evaporation of water can create a cooling effect. The chamber is an above-ground double-walled structure made up of bricks. The cavity of the double wall is filled with riverbed sand.

The ability of a cell to generate into a whole plant is known as Totipotency.
Totipotency is defined as the ability of a single cell to divide and produce all the differentiated cells in an organism, including extraembryonic tissues. Totipotent cells formed during sexual and asexual reproduction include spores and zygotes.
Gottlieb Haberlandt discovered totipotency. He is known as the father of plant tissue culture.
Totipotency plays an important role in tissue culture as a single can be cultured to form the complete organism.

Natural cytokinin is Zeatin.
The most common is zeatin, which was the first natural cytokinin to be identified. It is purified from immature maize kernels and named 'zeatin'.
They facilitate the growth of lateral buds when sprayed on meristems triggering cell division for the production of bushier plants. It occurs in the form of a cis- and a trans-isomer and conjugates.

Prunus cerasus is cooking cherry.
Prunus cerasus (sour cherry, tart cherry or dwarf cherry) is a species of Prunus in the subgenus Cerasus (cherries), native to much of Europe and southwest Asia.
It is closely related to the sweet cherry (Prunus avium) but has a more acidic fruit. Its sour pulp is edible.

The Agriculture and Processed Food Products Export Development Authority (APEDA) was established in 1986 under the Ministry of Commerce, Government of India. The primary objective of APEDA is to promote the export of processed agricultural products from India.

APEDA plays a crucial role in supporting and promoting the export of various agricultural products such as fruits, vegetables, spices, meat, and processed foods. It also helps in implementing quality standards and providing financial assistance to exporters.

Therefore, the correct answer is Option E: 1986, as APEDA was officially formed in this year to foster the development of agricultural exports.

The red colour of tomato is due to pigment Lycopene. It is produced in tomatoes from the carotenoid biosynthesis pathway.
Lycopene is a type of organic pigment called a carotenoid. It is related to beta-carotene and gives some vegetables and fruits (e.g., tomatoes) a red colour.
Lycopene is a powerful antioxidant with many health benefits, including sun protection, improved heart health and a lower risk of certain types of cancer. It may be most effective when consumed from lycopene-rich foods like tomatoes and other red or pink fruits.

In the hexagonal system of planting about 15 percent of trees can be planted as compared to the square method.
In a square system, trees are planted on each corner of a square whatever may be the planting distance. This is the most commonly followed system and is very easy to lay out. The central place between four trees may be advantageously used to raise short-lived filler trees.
In the hexagonal method of planting, the trees are planted in each corner of an equilateral triangle. This way six trees form a hexagon with the seventh tree in the centre. Therefore this system is also called 'septule' as a seventh tree is accommodated in the centre of the hexagon.
Thus as compared to the square system, the hexagonal system accommodates 15% more plants. In the hexagonal system, the trees are planted in the corners of equilateral triangles. Six trees thus form a hexagon with another tree at its centre.

Pinching of male buds before anthesis in the female parents of cucurbitaceous vegetables was 1^st suggested by Choudhary and Singh.
F1 hybrid production in Cucurbitaceae can economically be done on large scale by pinching all the male flowers before opening from the female parent and the male parent is allowed to grow side alongside the side of a female parent for natural cross-pollination in isolation.
One row of the male parent can be sown after every three rows of the female parent as suggested by Chaudhary and Singh, in 1971 for producing F1 hybrid seeds.

Spanish day is the common name for the Yucca plant.
Yucca is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae. Its 40 - 50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers.
The Aztecs living in Mexico since before the Spanish arrival, in Nahuatl, call the local yucca species (Yucca gigantea) iczotl, which gave the name Spanish izote or Spanish day.

AICVIP was shifted from IARI, New Delhi to Varanasi in 1991.
The All India Coordinated Research Project on Vegetable crops was started during the fourth five-year plan in 1970 - 71, to provide a national network for multi-location testing of vegetable technologies.
In a significant development in 1991, headquarter of the directorate was shifted from IARI, New Delhi to Varanasi. Later on, the PDVR was elevated to the Indian Institute of Vegetable Research (ICAR-IIVR) in 1999.
