Every hybrid seeds or crop produced on a commercial scale have some unique qualities other than natural ones. Apart from high yield, they may also have pest control, a taste enhancer, good nutrient quality, etc. likewise hybrid maize also shows high yield unlike natural maize i.e. 20 kg/hectare for CO 1 and TNAU maize hybrid CO 6 and 25 kg/ha for COBC 1.

The common bread wheat that we use as our staple food is hexaploid. Root cells of wheat have 2n = 42 chromosome that is diploid chromosome number of 42 is six sets of the basic unit. And the basic unit can be obtained by dividing 42 by 6; $$\left( {\frac{{42}}{6} = 7} \right)$$   i.e. each set has 7 chromosomes.

Brassica is the genus of any mustard but the species differ. So, the scientific name of Indian mustard is Brassica juncea. Commonly also called Brown mustard, Chinese mustard, Indian mustard, leaf mustard, oriental mustard and vegetable mustard.

Sunflower oil is considered one of the healthy options in oils because it contains high quantities of unsaturated fatty acids. It contains more than 80% of monounsaturated fats which makes it healthy for our hearts. It helps in maintaining a balance in our bodies.

* Relative weeds are plants that are closely related to the crop you're trying to grow.
* Think of it like this: if you're growing a specific type of rice, but a different variety of rice grows in the same field, that different rice variety acts like a weed.
* It competes for resources like sunlight, water, and nutrients just like a typical weed would.

Now let's look at why the other options aren't correct:

* Option B: Plants of other crop in the crop field This describes a volunteer plant or a weed but not specifically a "relative weed."
* Option C: Seasonal weeds in the crop field This is a general description of common weeds that appear during a specific season.
* Option D: All of these Since A is the only correct answer, this option is incorrect.

So, relative weeds are essentially unwanted varieties of the same crop growing alongside the desired variety.

Subsidy on fertilizers was announced by the Government of India in years 73 - 74 due to a rise in prices but acted with effect from 1^st November 1977. It was named DBT i.e Direct Benefit Transfer scheme in fertilizers. Under this scheme, the farmers will get the subsidy amount directly in their bank accounts for the purchase of fertilizers. This was an excellent initiative taken for farmers which lead to high quality and productive farms in India.

Excess uptake of potassium is known as luxury consumption. It is the tendency of some crops that can absorb nutrients in excess when available in abundance in soil but at the same time, it does not influence yield.

The application of nitrogen in pulses at the time of planting is known as the starter dose. It is well known that legumes require nitrogen in abundance so nitrogen fixing bacteria are also present at root nodules for fixing nitrogen available in the atmosphere for more protein synthesis in seeds that is why legumes are rich in protein. So, once at the time of sowing dose of nitrogen is given to plants later they produce their own by symbiotic association with bacteria.
