Most agriculture in India is rain-fed, that is, the success of crops in most areas is dependent on timely monsoons and sufficient rainfall spread through most of the growing season. Hence, poor monsoons cause crop failure. Ensuring that the crops get water at the right stages during their growing season can increase the expected yields …
Manure contains large quantities of organic matter and also supplies small quantities of nutrients to the soil. Manure is prepared by the decomposition of animal excreta and plant waste. Manure helps in enriching soil with nutrients and organic matter and increasing soil fertility. The bulk of organic matter in manure helps in improving the soil …
Management and Improvement of Crop Production One can appreciate how challenging it must be to create a plan to boost crop yields that would benefit everyone equally given the vast geographical variation witnessed in India. Varied regions of India have different types of soil, varying amounts of rainfall, varying amounts of groundwater reserves, and of …
Heat is trapped by glass, and hence the temperature inside a glass enclosure will be much higher than the surroundings. This phenomenon was used to create an enclosure where tropical plants could be kept warm during the winters in colder climates. Such enclosures are called greenhouses. Greenhouses have also lent their name to an atmospheric …
One of the most important natural resources on planet, water has existed for a very long period. In reality, the water that we drink today has existed in some capacity since the time of the dinosaurs.More than two thirds of the earth’s surface is covered in water. The amount of water dispersed throughout the oceans, …
All cells possess the ability to respond to stimuli. However, cells of the nervous tissue are highly specialised for being stimulated and then transmitting the stimulus very rapidly from one place to another within the body. The brain, spinal cord and nerves are all composed of the nervous tissue. The cells of this tissue are …
Muscular tissue consists of elongated cells, also called muscle fibres. This tissue is responsible for movement in our body. Muscles contain special proteins called contractile proteins, which contract and relax to cause movement. We can move some muscles by conscious will. Muscles present in our limbs move when we want them to, and stop when …
Blood is a type of connective tissue. A clue is provided in the introduction of this chapter! Now, let us look at this type of tissue in some more detail. The cells of connective tissue are loosely spaced and embedded in an intercellular matrix . The matrix may be jelly like, fluid, dense or rigid. …
