Question

Which of the following oilseeds is grown in India in both Rabi and Kharif seasons?

A. Groundnut

B. Coconut

C. Castor seed

D. Mustard

Answer 1

Hint: The scientific name of this oilseed is Ricinus communis. It is referred to as a species of perennial flowering plant in the spurge family, Euphorbiaceae. It is also the sole species in the monotypic genus, Ricinus, and subtribe, Ricinine.

Complete answer:

Traditionally, castor is referred to as a kharif season crop. Somehow, with the introduction of new, early and high yielding varieties and hybrids, its cultivation is now extended to rabi and summer seasons as well. Summer season is generally not considered ideal for commercial cultivation of castor, except for the seed production of castor.

Castor seed is grown both as rabi and kharif crop. Castor seed is the major source of castor oil that has numerous uses. It is a vital non-edible oil seed crop which is particularly grown in arid and semi-arid regions. It is harvested in winters from October to December and are harvested in summers in the months of April to June. Kharif crops are grown with the onset of monsoon in distinct parts of the country and these are harvested in the months of September-October.

Castor plants are likely to grow in full sun and humid conditions. Loamy, moist, but not soaking wet, soil is needed for best results. Seeds are soaked overnight to aid with germination. In warmer areas, or once the soil can be worked and the threat of frost has passed, castor bean seeds can also be sown straight into the garden.

Hence, the correct answer is option C.

Note: The Rabi in general means the time when the crop is harvested. Crops which are grown in the winter season, starting from November to April are known as Rabi Crops. Some of the important rabi crops are wheat, barley, peas, gram and mustard. However, some of the Rabi Crops are harvested around March-April each year.
