CPCRI is Central Plantation Crops Research Institute was established in 1970 under the Indian Council of Agricultural Research at Kudlu, Kasaragod, Kerela.
It serves as a national forum for improving the genetic potential of plantation crops and conducting basic and applied research on various aspects of these crops to produce genetically superior planting materials for coconut, Arecanut, cashew nut and spices.

Mixed cropping is growing two or more crops in the same field at the same time. Mustard a leguminous crop is best to be grown with wheat in the same field. This mixture consists of broadcasting mustard seed after sowing of wheat in the field, followed by planting.

Paspalum scrobiculatum, commonly called Kodo millet, is an annual grain that is grown primarily in Nepal. Millets fall in the category of coarse millet, hence it is also a very hard and coarse crop that is drought tolerant and can survive on marginal soils also. Kodo millet has a large potential to provide nourishing food to subsistence farmers.

Red rot of sugarcane is a disease first reported in Java in 1893 caused by fungus.
It can be controlled and minimized by following crop rotation with non-hosts and application of appropriate foliar fungicides. Now resistant sugarcane varieties are also available which is the best method to stop infection.

Anions are negatively charged ions while cations are positively charged ions.
Anions are the type of ions that have gained electrons.
Boron, chloride, molybdenum, phosphorus and sulphur are the essential nutrients that are absorbed as anions by plants for normal growth and development of the plant.

Auxin and cytokinin are the phytohormones that control root initiation, cell elongation and apical dominance.
Auxins play a cardinal role in the coordination of many growths and behavioral processes in plant life cycles and are essential for plant body development. The Dutch biologist Frits Warmolt Went described the role of auxins in plant growth for the first time in 1920.

Pusa Giant is a vigorous variety of papaya.
It is gynodioecious variety with 100% productive plants with good fruit yield and quality having excellent taste. The plants are sturdy and tolerant of strong winds. The first fruit is at one-meter height and it weighs 2 - 3 kg with yellow, moderately firm 5 cm thick pulp. The fruits are suitable for tooty-fruity.

Sunflowers act as an indicator plant to diagnose the deficiency of boron in the soil as definite boron deficiency symptoms are developed in sunflowers.
The young and middle leaves of the plants develop small chlorotic patches and develop orange-colored necrotic areas in the young leaves.

The term “Green revolution” was coined by William S. Gaud, the administrator of the U. S. Agency for International Development (USAID), in March 1968.
The introduction of this green revolution in India has converted agriculture into the modern industrial system by the adoption of technology like the use of HYV (high yielding variety) seeds, mechanized farm tools, irrigation facilities, pesticides and fertilizers.
