Cotton (Gossypium hirsutum L.) is one of the main cash crops of
Pakistan. It has played a significant role in industrial development and
employment generation. It is known as backbone of Pakistan‟s economy.
Its impact on the economic development of the country is well
established and it is rightly known as silver fiber of Pakistan. It
occupies the 2nd position with respect to cultivated area in the
country. During 2007-08 the cotton production was 12 million bales from
an area of 3.05 million ha (Anonymous, 2008). Chemical fertilizers which
have nutrients available, can provide sufficient nutrients to the crops,
but their cost and constrains frequently deter farmers from using them
in recommended quantities and balanced proportions. Moreover, limited
availability of chemical fertilizers and their high cost are making
their use difficult for the farmers. No doubt, use of chemical
fertilizer provides essential nutrients for crop improvement to obtain
higher yields; however, data of recent years reflect that the crop
yields in Pakistan are almost stagnant. This situation warrants the use
of organic sources of nutrients.
