Improvement in Food Resources : Types of Revolution

Green revolution

Green rev­o­lu­tion is a pro­gram intro­duced in many coun­tries to increase food pro­duc­tion by used of mod­ern tech­nol­o­gy prop­a­ga­tion improve seeds etc. 

White revolution

White Rev­o­lu­tion is a pro­gram in India to increase pro­duc­tion of milk in India. 

Improve­ment in crop yields

Types of crops

a) Cere­als : they include crops like wheat ‚rice, maize, bar­ley etc. They pro­vide us carbohydrates. 

b) Seeds : not all cheats of clans are edi­ble like seats of apple or cherry. 

Edi­ble seeds include seri­als puls­es oil seeds and nuts. 

They pro­vide us fats. 

c) Puls­es : they include legumes such as gram ‚pea, black gram, green gram, lentil. They pro­vide us proteins. 

d) Veg­eta­bles, Spices and Fruits : They pro­vide us vit­a­mins and minerals. 

they include apple, man­go, cher­ry, banana, water melin etc. 

Veg­eta­bles like spinach, leafy veg­eta­bles, car­rot etc. 

Spices like chilly, black pep­per, cin­na­mon, fen­nel etc. 

e) Fod­der crops — They pro­vide green fod­der to the cat­tle eg — oats, sorghum etc. 

Crop Sea­son

Dif­fer­ent crops require dif­fer­ent con­di­tions like tem­per­a­ture Mon­ster etc dif­fer­ent pho­to peri­ods dura­tion of Sun­light for their growth and com­plet­ing life cycle. 

The two types of crops season are:-

• a) Kharif Sea­son: These crops grow dur­ing rainy sea­son ( June to Octo­ber). They are also called sum­mer sea­son crops. Eg of Kharif crops are black gram, green gram, pigeon pea, rice, pad­dy, soybean. 
• b) Rabi Sea­son: The crops are grown dur­ing Novem­ber to April. 

Rabi crops are known as win­ter crops. 

Eg.Wheat, gram, peas, mus­tard, lin­seed etc. 

Approach­es which enhance the crop yields are as follows:-

• Crop vari­ety improvement
• Crop pro­duc­tion Improvement
• Crop pro­tec­tion improvement
• Crop Vari­ety Improve­ment:- Fac­tors by which vari­ety improve­ment can be done are:-
• Good and healthy seeds. 
• Hybridi­s­a­tion:- It is the process of cross­ing between two or more genet­i­cal­ly dis­sim­i­lar plants to pro­duce a new vari­ety with good prop­er­ties of both the crops.
