- NUTRITIOUS VALUE AND USES OF MAIZE
Maize has an assortment of employments. Its grain is a rich wellspring of starch 72%, nutrients A
and B 3 – 5%, proteins 10%, 4.8% oil, 5.8 % fiber, 3.0% sugar and 1.7% debris. One
hundred gram of new grain contains 361 calories of vitality, 9.4g protein; 4.3g

fat, 74.4g starch, 1.8g fiber, 1.3g debris, 10.6 percent water, 140mg nutrients,
9mg calcium, 290mg, phosphorus and 2.5mg iron. It is a wellspring of crude material
for industry, where it is as a rule widely utilized for the planning of corn starch,
corn oil, dextrose, corn syrup, corn pieces, beauty care products, wax, liquor and tanning
material for calfskin industry.
Ethanol got from maize can be utilized as a biomass fuel. Marks of disgrace from
female corn blossoms, known as corn silk, can be utilized as home grown enhancements.
Maize can be utilized as rummage, feed for domesticated animals and making silage after
aging of corn stocks. Maize is utilized broadly as the fundamental wellspring of
calories in creature taking care of and feed plan. Maize gives the most noteworthy
transformation of dry substance to meat, milk and eggs contrasted with other grain
grains. Maize is an important feed grain, since it is among the most elevated in net
vitality content and most reduced in protein and fiber content. Creatures like and eat it
promptly.
- Development HABITS
It is yearly cross-pollinated crop having erect, thick and solid culms or tail
with hubs and internodes. The corn leaf comprises of the edge, sheath and neckline
like ligule. It is regularly monoecious with staminate and pistillate blossoms produce
on the tuft and ear. Run of the mill corn plant creates 20 to 21 all out leaves, silk about
65 days after development, and develop around 100 – 125 days after rise.
The particular time interim, nonetheless, can differ among cross breeds, conditions,
planting date and area.
Development STAGES
A developing plant of maize goes through numerous development organizes as depicted underneath.
This is the growing stage which comes around multi week in the wake of planting and
plants have around 2 – 4 leaves at this stage.
This is knee stature phase of the plant which shows up around 35 to 45 days
subsequent to planting. Plants need first nitrogenous compost and last mechanical or
manual between development at this stage. In the event that this activity is deferred for certain days,
the leaves will be harmed.
This stage is all the more actually called as blooming commencement stage. At this
stage, the tufts (male blossoms) are shaped at the pinnacle of the plant after 14 to 15

forgets about have come. Last utilization of nitrogenous composts is done at this
stage. Compost application after this stage doesn't give any reaction.
This phase of maize plant is otherwise called brush commencement stage. At this
stage the female blossoms or cobs are shaped in the pivot of the thirteenth of leaf.
This may likewise be called as smooth stage. It begins after fertilization and
preparation are finished. At this stage, grains begin growing yet they don't
become hard. This stage might be speculated by observing the silks on the highest point of the cob
which remain incompletely green and the covering of the cobs likewise stay green at
this stage. This is the best stage for utilizing the green cob for table purposes.
This is the development stage at which the leaves get dried, silks disappear or they get
dried totally and turn out to be exceptionally weak. Collecting ought to be done at this
stage.
Cross breed VARIETIES
Hereditary adjusted (GM) corn is being embraced over the globe and
Pakistani ranchers can likewise profit a great deal by utilizing GM corn as it can essentially
lessen the misfortunes brought about by different creepy crawly nuisances, weeds and in this manner cost of
creation would descend. After the presentation of crossover maize during the
1990s, ranchers have step by step moved to mixture maize from conventional/Open
Pollinated Varieties (OPVs) as crossover maize has expanded creation from a negligible
30 mound/section of land to 80-120 mound/section of land. The hole between the acknowledged and
potential yields can be crossed over up by embracing reasonable agronomic practices and
limiting the biotic and antibiotic weights on the harvest.
There are two primary organizations have a decent quality crossover seeds for example Pioneer,
Monsanto. The maize half and halves have ability of delivering in excess of 12 tones
grains per hectare which is high as contrasted and 3.48 tons per hectare, the
normal yield of maize in Pakistan.
Maize is adjusted to wide assortment of soil yet to get more yields it requires fruitful
profound and all around depleted soils. Soils with a pH scope of 6.5 – 7.5 are generally great.
All around depleted, overwhelming soils with high natural issue substance and great water
holding limit give high creation. Waterlogged soil is generally unsafe for its
development.
Maize is a warm climate plant and it develops from ocean level to 3000 meters
height. It very well may be become under differing climatic conditions moreover. It is developed in
numerous pieces of the nation consistently. Kharif (rainstorm) season is the
fundamental developing season. In any case, maize might be planted whenever from March to
October, as atmosphere is warm even in the winter season. Maize requires
extensive dampness and warmth from germination to blooming. The most
reasonable temperature for germination is 21°C and for development 32°C. Incredibly high
temperature and low dampness during blooming harm the foliage parch the
dust and meddle with legitimate fertilization, bringing about poor grain arrangement.
Maize is exceptionally touchy to stale water, especially during its beginning times of
development.
