write about intercropping and mixed cropping |
| Answer» \tMixed Farming refers to a cropping system where two or more crops are cultivated in the same piece of land simultaneously. This technique is practised to reduce the risk of total crop failure because of less rainfall or adverse climatic conditions.\tIntercropping is a cropping technique in which two or more crops are cultivated simultaneously in the same piece of land adhering to a specific row pattern in order to increase the productivity of the crops. This technique is generally followed by small farmers who are completely dependent on the rainfall for better yield and do not have any other options like canals and tube wells, etc. | |

What do you mean by mineral riches in the soil |
| Answer» Minerals are the largest component in the soil, making up almost 40% to 45% of the total components. The minerals in the soil are classified into two categories, namely\tPrimary Minerals in soil: These are minerals which have not been chemically altered since deposition. They are same or similar to their parent materials. Often these materials are bigger in size and irregular in shape. These primary minerals are usually found in sand and silt.\tSecondary Minerals in soil: These are minerals formed as a result of weathering of Primary Minerals. Secondary minerals are mainly found in fine silt or clay. The particle size of these minerals is much smaller, due to the weathering process. These minerals have a large surface area that helps them retain moisture. | |

In a plant name two features which would you examine to categorise it into monocot or dicot plants |
| Answer» We can examine the plant whether it is monocot or dicot on the basis of their structure of seeds, roots , leaves and stems.Seeds: A seed of a monocot plant has one cotyledon and that of a dicot plants has two cotyledons.Roots: Monocots have adventitious roots, whereas dicots have a radicle from which a root develops.Leaves: If the leaf has a stalk, then the plant is a dicot. But, in the case of a monocot plant, the leaf is sessile, which means it is attached directly by its base without a stalk.Leaves venation: If the leaves have parallel venations that are long and thin, then the plant is monocot. If the leaves have a branched venation, then the plant is a dicot.Stem: Monocot plants normally have a weak stem, whereas dicots have a strong stem.\xa0 | |

Why should preventive measures and biological control method be preferred for prootecting crops |
|
Answer» Preventive measures ensure that the crop plants are protected\xa0from the harmful biotic factors (such as diseases, weeds\xa0and insects) and abiotic factors (such as drought and salinity). Biotic and abiotic factors can cause huge losses of food grains and need\xa0proper treatment to control them. So it is better to take preventive measures and avoid loss in crop plant production.Using chemical control methods is not advisable since their use creates problems.\xa0They are poisonous to plant and animal species and cause environmental pollution. They reach human beings through the food chain. On the other hand, biological control methods are safe for plants, animals, humans and the environment in general.Hence, preventive measures & biological control methods are preferred for protecting crops. Weedicide harvesting threshing winnowing storage method be preferred for protecting crops |
