Beetroot is also known as garden beet. This sweet, healthy vegetable is loaded with antioxidants. The plant is edible in its entirety, from the leaves to the root. The taproot ranges in shape from globular to long and tapered.  Skin and flesh colours are usually dark purplish red, though some are nearly white or orange.  Beets are a cool-weather crop that should be planted in early to midspring and late summer to early fall. They have a short enough growth cycle that you can actually plant them at any time, as long as you can keep them fairly cool. 
 
Beets are earthy, delicious vegetables that are easy to grow in a garden or in a greenhouse. They can even grow them in pots indoors or on the porch. As with many root vegetables, beets are easy to store, making them an ideal vegetable to stock up on for long winters.

Onion (Allium cepa) is a herbaceous biennial plant of the amaryllis family (Amaryllidaceae) grown for  its edible bulb. The onion is likely native to southwestern Asia but is now grown throughout the  world, chiefly in the temperate zones. Onions are low in nutrients but are valued for their flavour  and are used widely in cooking. They add flavour to dishes like stews, roasts, soups, and  salads and are also served as a cooked and raw vegetable.

Onions are very hardy and can survive in a wide range of growing conditions. The bulbs  vary in size, shape, colour, and pungency, though warmer climates generally produce  onions with a milder, sweeter flavour.  The onion’s characteristic pungency results from the sulfur-rich volatile oil it contains; the  release of this oil during peeling or chopping brings tears to the eyes

Brinjal is a rather small plant that grows up to 1.5 m. The plant is classified as a herb because of its non-woody stem. Its simple leaves are oblong to oval, slightly lobed, with its underside a paler green than the upper surface. Both leaves and stem are covered with fine hairs. Its flowers sprout singly or in small clusters from the leaf axils. Its fruits are berries with many seeds and are either long or round and vary in color according to the variety: white, orange, green, purple or black. It is a perennial and fruits all year round.

Brinjal is a crop grown in warm weather and requires a warm growing season. It is very susceptible to frost. It can be successfully grown in a rainy and summer season crop and can grow at an elevation of 1200m above the sea level.
