Hybridisation. It is crossing of two (or more) types of individuals with different useful traits in order to bring them together in the progeny. Photoperiod. light is duration of day light that influences plants and other organisms in their growth, reproduction and maturation

Use of excess fertilizers tend to cause: (i) Mineral loading of underground water. (ii) Excess minerals in the crop plants. (iii) Salinization of soil. (iv) Run off from fertilizers rich soil, will cause eutrophication of water bodies

Organic matter forms humus. It is essential for crop production because it makes the soil fertile. matter Organic has the following advantages: (i) It improves soil structure by forming soil crumbs. (ii) It increases water holding capacity of sandy soils. (iii) It improves aeration of clayey soils.Read more

(i) It improves soil structure by forming soil crumbs.
(ii) It increases water holding capacity of sandy soils.
(iii) It improves aeration of clayey soils.
(iv) During its decomposition, it liberates minerals (inorganic molecules) which enrich the soil.
(v) Biochemicals present in decaying organic matter improve growth of crop plants.
GM or genetically modified crop is the one which has been developed through introduction of some specific genes from other sources, e.g., insect resistant Bt cotton (being grown in India), vitamin A rich Golden rice.

What is GM crop? Name any one crop which is grown in India.
GM or genetically modified crop is the one which has been developed through introduction of some specific genes from other sources, e.g., insect resistant Bt cotton (being grown in India), vitamin A rich Golden rice.
