ABSTRACT
Maize pollen is anemophilous (dispersed by wind) and because of its large settling velocity most pollen falls within a few meters of the tassel. Each silk may become pollinated to produce one kernel of maize. All maize varieties follow same general pattern of development, although specific time and interval between stages and total number of leaves developed may vary between different hybrids, seasons, time of planting and location. The various stages of maize growth are broadly divided into the vegetative and reproductive stages. Normally maize plants have three types of roots, seminal roots – which develop from radicle and persist for long period, adventitious roots, fibrous roots developing from the lower nodes of stem below ground level which are the effective and active roots of plant and brace or prop roots, produced by lower two nodes.
