• The climatic conditions required for various crops are as follows:
Barley: The crop requires around 12-15°C cooler environment during growing period and around 30°C at maturity.
​It cannot tolerate frost at any stage of growth and incidence of frost at flowering at highly detrimental for yield.
The geographical conditions for barley cultivation are almost the same as for wheat, but barley is more tolerant of dry conditions and will ripen at lower temperatures.
The most suitable soil for barley cultivation is the light, sandy or dry soil. 
Rice: Rice crop needs a hot and humid climate.
It is best suited to regions which have high humidity, prolonged sunshine and an assured supply of water.
The average temperature required throughout the life period of the crop ranges from 21 to 37°C.
Fertile riverine alluvial soil is best for rice cultivation. 
Millets: It is a rainfed crop mostly grown in moist areas which hardly needs irrigation.
This crop requires moderate rainfall of 30-100cm and high temperatures ranging from 20 to 32°C.
Both excessive moisture and prolonged drought are harmful.
Well drained light soils are ideal.
Pearl millet will yield best on fertile, well-drained loamy soils.
Tea: Tea requires a temperature ranging from 21°C to 29°C.
​Tea grows well in the regions which receive rainfall in between 150-200 cm.
The soil should be well drained.
However, stagnant water damages the tea crops.
Tea is grown in a variety of soils.
The best, however, is a light friable loam with porous sub-soil which permits a free percolation of water, for tea is highly intolerant to stagnant water.
