Which among the following can be produced with the help of the SRI method of production? 
» Explain it
The System of Rice Intensification (SRI) is a system that is aimed at development of a low-water requirement, labour-intensive method of production of rice. It uses younger seedlings singly spaced and typically hand weeded with special tools. It was developed in 1983 by the French Jesuit Father Henri de Laulanié in Madagasca though the extensive usage was done later by Cornell University etc. 

Hence, option A is correct.
Which among the following is associated with Golden Rice?
» Explain it
Golden Rice is a variety of rice produced through genetic engineering to biosynthesize beta-carotene, a precursor to Vitamin A, in the edible parts of rice. It is very much useful for fighting the deficiency of Vitamin A which is the major cause of death of children every year. This variety of rice is mainly different from its parental strain by the addition of three beta-carotene biosynthesis genes. 

Hence, option D is correct.
» Explain it
Site Specific Nutrient Management is a rice-wheat cropping (200 percent intensity) showed 36% higher grain yield accruing 2 tonnes / ha more yield than the usual practice of the farmers with fair benefit / cost ratio of 5.8, which means that every extra rupee invested in this method over the normal practice gives extra crop value of Rs 5.80 on a net basis. This method is popular among the farmers for its better production value. 

Hence, option B is correct.
A crop that is cultivated in order to nurture another crop is known as ________. 
» Explain it
In agriculture, a nurse crop is cultivated on an annual basis in order to nurture another perennial crop. The widest use of such crops is in the establishment of legumaceous plants such as alfalfa, clover and trefoil. Nurse crops reduce the incidence of weeds, prevent erosion and also prevent excessive sunlight from reaching the tender seedlings. These nurse crops are cultivated for straw, hay or pasture. 

Hence, option C is correct.
Farmers grow which among the following in order to send vegetable crops to the distant markets?
» Explain it
Truck Crops are grown by the farmers in order to send vegetables on a large scale to the distant markets. Fresh shipments are done by trucks to the distant markets, for one or more than one vegetables. Important truck crops include onions, cabbage, beets, lettuce etc. 

Hence, option C is correct.
