Name any two common Indian millet crops. State one characteristic of millets that has been improved as a result of hybird breeding as to produce high yielding millet crops.

Explain any one method of crop production which ensures high yield.

Explain any one method of crop production which ensures high yield.

These questions consist of two statements each, printed as Assertion and Reason. While answerng this questions are required to choose any one of the following four responses: If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion. If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion. If Assertion is true but Reason is false. If both Assertion and Reason are false. Cattle breeds can be improved by superovulation and embryo transfer. Superovulation in high milk-yielding cows is induced by hormonal injections.

These questions consist two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses. If both Assertion and Reason are true and Reason is correct explanation of Assertion. If both Assertion and Reason are true but Reason is not correct explanation of Assertion. If Assertion is true but Reason is false. If both Assertion and Reason are false. Assertion:'Bt' toxin gene has been cloned from bacteria and expressed in plants to provide resistance from insect wihtout in need of insecticides. Reason: 'Bt' toxin is produced from bacterium Bacillus thuringiensis.

Sanya has a piece of land which is in the shape of a rhombus (See Fig. ). She wants her one daughter and one son to work on the land and produce different crops to suffice the needs of their family. She divided the land in two parts by joining its opposite comers. If the perimeter of the land is 400 m and one of the diagonals is 160 m, how much area each of them will get to work on.

If Assertion is true but Reason is false. D. If both Assertion and Reason are false. Assertion. High yielding variety of rice was produced in India by introduction of dwarfing genes called Dee-goo-woo-gen from Taiwan. Reason: High yielding variety of wheat was produced form dwarfing genes of Norin-10 from Japan in India.

These questions consist of two statements each, printed as Assertion and Reason. While answering these questions,you are requied to choose any one of the following four responses If both Assertion and Reason are true and Reason is a correct explanation of the assertion If both Assertion and REason are true but Reason is not a correct explanation of the Assertion If Assertion is true but Reason is false If both Assertion and Reason is false. Assertion: HIgh yielding variety of rice was produced in india by introduction of drawfing genes called Dee-goo-woo-gen from Taiwan. Reason: HIgh yielding variety of wheat was produced from drawfing genes of NOrin-10 from Japan in India.

How has the mutation breeding helped in improving crop varieties? Give one example where this technique helped.
