Crops of Kharif Season
Kharif (or southwesterly
monsoon) crops include rice, maize, Jawar, bajra, groundnut, cotton and other
crops.
Rice
Rice cultivation in
India stretches from 8ï‚ o latitude to 34ï‚ o N latitude. Rice is also grown in areas
below the sea level (as in the Kuttanad region of Kerala) as well as at
altitudes of about 2000 m (as in parts of Jammu and Kashmir). High rainfall or
assured irrigation is essential for the areas of rice cultivation. Rice crop
requires about 30 cm of water per month during the growing period stretching
from about 3 to 8 months. Rice is grown on about 40 Mha in the country. This
area also includes about 7 Mha which is saline, alkaline or floodprone. Twentyfive
percent of the rice growing area has assured irrigation and about 55 per cent
of the rice growing area is illdrained or waterlogged. The rest of the ricegrowing
area is rained uplands where the rainfall is marginal to moderate and its
distribution is erratic.
Rice cultivation in
India is either upland cultivation or lowland cultivation. The upland system of
cultivation is confined to such areas which do not assured irrigation
facilities. In this system, fields are ploughed in summer, farmyard manure is
uniformly disturbed 23 weeks before sowing , and the rain water is impounded in
the field until the crop is about 4560 days old.
In the lowland system
of rice cultivation, the land is ploughed when 510 cm of water is standing in
the field. Seeds may be sown after sprouting. Alternatively, seedlings which
are 2530 days old are transplanted. The nursery area required to provide
seedlings for transplanting on one hectare is roughtly onetwentieth of a
hectare. The water requirement of lowland rice cultivation is much higher than
that of other cereal crops with similar duration.
Maize
Maize is one of the
main cereals of the world and ranks first in the average yield. It world
average yield of 27.8 qunitals/ hectare (q/ha) is followed by the average
yields of rice (225.5q/ha), Wheat (16.3 q/ha) and millets (6.6 q/ha). In terms
of area of maiza cultivation, India ran fifth (after USA, Brazil, China and
Mexico) in the world. However, India stands eleventh the world in terms of
maiza production. Within India, maiza production ranks only next rice, wheat,
jawar and bajra in terms of area as well as production. Most of the maize
cultivation (around 75 per cent) is in the states of Uttar Pradesh (1.4 Mha),
Bihar (0.96 Mha), Madhya Pradesh ( 0.58 Mha), Rajasthan (0.78 Mha) and Punjab
(0.52 Mha).
Maize requires deep and
well drained fertile soils, but can be grown on any type of sc ranging from
heavy clays to light sands provided that the pH does not deviate from the range
7.5 to 8.5. Maize plants, particularly in these seedling stage, are highly
susceptible to salinificant and water logging, and hence, proper drainage of
the land is essential for the successfully cultivation of maize. Over 85 per
cent of the crop area in India is rainfed during the monsoon.
Maize is essentially a
warm weather crop grown in different regions of the world ranging from tropical
to temperature ones. It cannot withstand frost at any stage of its growth. In
India its cultivation extends from the hot arid plains of Rajasthan and Gujarat
to the wet regions Assam and West Bengal.
Maize is a short
â€'duration (8095) crop and, hence can conveniently fit into a wid range of crop
rotations. It is usually grown as a pure crop, but sometimes legumes (e.g.,
moong arhar or beans), and quick â€'growing vegetables (e.g. pumpkins, gourds)
are grown as mixed crops with it.
The sowing of maize
starts 710 days before the usual date of the onset of monsoon. One irrigation
at the initial stage is useful for the establishment of seedlings and the crop
yield is increased by about 1520 per cent. The maize crop is harvested when the
grain are nearly dry and do not contain more than 20 per cent moisture. Maize
is grown for grains as well as fodder.
Sorghum (Jawar)
Sorghum (popularly
known as jawar) is the main food and fodder crop of dry land agriculture. It is
grown over an area of about 18 Mha within the average yield of about 600 kg/ha
. Jawar cultivation is concentrated mainly in the peninsular and central India,
Andhra Pradesh, Gujarat, Karnataka, Madhya Pradesh, Maharastra, Rajasthan,
TamilNaud, and Uttar Pradesh are the major jawargrowing states. Jawar is mainly
grown where rainfall distribution ranges from 1020 cm per month for at least 3
to 4 months of the south â€'westerly monsoon.
Sorghum is grown during
both kharif (JulyOctober) and Rabi (October â€'February) seasons. The Rabi
cultivation of jawar constitutes about 37 per cent of the total jawar growing
area. Sorghum cultivation still remains predominantly traditional in most parts
of the country. Mixed cropping of jawar and arhar (tur) is very common.
Harvesting and threshing are still carried out manually or with bullock power.
The national average yields are still low and around 500 kg/ha. However, the
highyielding hybrid varieties can yield 20003000 kg/ha under average growing conditions.
Spiked Millet (Bajra)
Bajra is a drought crop
which is generally preferred in low rainfall areas and lighter soils. It is
grown in Rajasthan, Maharashtra, Gujarat, and Uttar Pradesh. Over 66 per cent
of this crop is grown in areas receiving 1020 cm per month of rainfall,
extending over 1 to 4 months of the south
â€'westerly monsoons. It
should be noted that jawar and bajra are grown mostly under identical
environmental conditions and both have a wide range of adaptability to drought,
temperature, and soil.
Groundnut
Groundnut is grown over
an aea of about 7 Mha concentrated in the states of Gujarat (24 percent),
Andhra Pradesh (20 Per cent), Karnataka (12 per cent), Maharashtra (12 per
cent), and Tamil Nadu (13 per cent ). Madhya Pradesh, Orissa, Punjab,
Rajasthan, and Uttar Pradesh together have about 20 per cent of the total
groundnut producing area in the country. Groundnut is generaaly grown as a
rainfed Kharif crop. Groundnut is sown during May and June in the subtropics.
In the tropics, however, it is sown during either January and February or June
and July. Under rainfed conditions the average yield is 12001400 kg per
hectare.
Cotton:
Cotton occupies about
7.5 Mha in India, Maharashtra (36 per cent), Gujarat (21 per cent), Karnataka
(13 per cent), and Madhya Pradesh (9 per cent) are the leading states which
together grown cotton over an area of about 6 Mha. Other cotton growing states
are Punjab (5 per cent), Andhra Pradesh (4 per cent), Tamil Nadu (4 per cent),
Haryana (3 per cent, and Rajasthan (3 percent) Most of the cotton â€'growing
areas in the country are in the high to medium rainfall zones.
Cotton requires a welldrained
soil. It is grown as a rain fed crop in the black cotton and medium black soils
an as an irrigated crop in alluvial soils. The sowing season varies from region
to region and starts early (AprilMay) in north India.
