Agricultural Science: Crop Production and Management

Intercropping involves growing two or more crops simultaneously in a field, which helps prevent the spread of diseases and pests by creating biodiversity and disrupting pest cycles.

The Yellow Revolution refers to the increase in oilseed production in India during the 1980s. It aimed to boost domestic oil production and reduce dependence on imports.

Mixed cropping is the practice of growing two or more crops simultaneously on the same piece of land without a fixed pattern. This helps optimize land use and reduces risk.

Blank-shank or black shank of tobacco is caused by the oomycete Phytophthora nicotianae. It is a serious disease affecting tobacco plants, causing stem and root rot.

Intravarietal hybridization involves crossing plants within the same variety. This is different from intervarietal (between varieties) or interspecific (between species) hybridization.

Mass selection is the technique where individual plants with superior phenotypic characteristics are selected from a population for further propagation. It is based on observable traits.

Hybridization is the process of crossing two genetically different plants to incorporate desirable characteristics from both parents into a new crop variety.
