Cotton is an important fiber crop of Pakistan and is also the
second most important oilseed crop in the world. The cotton plant
possesses a narrow range of ecological adaptability and is very
much influenced by the climatic conditions. Among many factors
causing low yield, sowing time and plant spacing are more
important. Therefore, the present study was designed to investigate
the effect of different sowing times and plant distances on the
growth, seed cotton yield and quality of cotton genotype BH-160
under the agro-ecological conditions of Rahim Yar Khan in irrigated
environment. It may be concluded from this study that the boll
number, boll weight and yield per plant decreased with closer
spacing but seed cotton yield per hectare increased. The 15 cm
plant to plant spacing produced more seed cotton yield due to more
number to of plants per hectare, which compensated the other, yield
components. Plants spacing however did not affect G.O.T%, seed
index and fibre quality and plant height. Sowing date of 15th May
gave maximum seed cotton yield and did not effect on monopodial
branches.
Phosphorus and Zn deficiencies are common nutritional restrictions
to crop production in the soils of Pakistan. The P-Zn interactions
in plants have been examined in the past but their interaction
effects on economic yield of crops are still confusing,
particularly in sandy clay loam soils. For these reasons, a field
experiment was laid out in RCBD-factorial with three replications.
It is concluded from this experiment that the treatment with 40 kg
P and 8 kg Zn ha-1 gave the best combination of phosphorus and zinc
levels at 100 kg N ha-1. It is also the most suitable from economic
point of view as it gave maximum benefit cost ratio and value cost
ratio along with high net income.
Maize is an important cereal crop world wide, not only as a staple
food in various parts of the world, but also as a major component
of feeds for the animals. Adapted to a wide range of climates, the
crop is mostly grown between latitudes 30 and 55, principally in
latitudes below 47 . It is a warm weather crop, doing best when
temperatures in the warm months range from 21 to 27 C. The
judicious use of organic and mineral fertilizers may increase
micronutrient density in grain destined for human consumption and
play a promising rule in reducing human's micronutrient deficiency.
The integrated nutrient management for crop improvement has been
paid little attention in agriculture areas of developing world.
Therefore, the present study was executed to evaluate the
integrated nutrients use affect on growth, yield and quality of
maize.
Agriculture is an important sector of the country economy providing
basic commodity of the daily use. The total cultivated area in the
province is 2.75 million ha. Charsadda is one of the 3rd important
district of Peshawar division. Total area of Charsadda district is
250250 acres; with 156924 acres irrigated.The major crops grown in
district Charsadda are sugarcane, wheat, tobacco and maize etc.
Moreover, different types of vegetables and fruits are also grown
in the district. The study is an attempt to analyze the different
problems of the farmers of District. The farmer facing the problem
of low literacy rate (34%), small land holding (10% farmers have
less then 2 acres), weak financial position of the farmers (80%),
irrigation water (66%), farm mechaneries (90%), fertilizers (62%),
pesticides (62%), un-availability of labour and flood is another
alarming situation for the farmers. The book in hand furnishes base
line information about the farmer's problem for educationist,
planer and all allied stalk holders. Therefore, it should be in
every library around the country.
Intercropping is experienced by preponderance of farmers in many
regions of the world. Intercropping has since long been used as
mean to cover the risk of failure of base crop and it can pilot to
boost food supply without retreating the sustainability of soil.
This system of cropping suppresses weeds, reduces pest disease
infestation, gives yield advantage and there is stable yield over
time. Crop fertilizer needs can be met with the addition of an
organic fertilizer, which is suitable for enhancing crop yields on
sustained basis and cost effective too. The use of legumes as an
intercrop can serve a potential source of organic fertilizer. It
can be used as a supplement source of nutrition especially that of
nitrogen. It is an economical way of food production as one input
such as N from legume can be applied once and used by all the crop
components in the farm thereby saving time for the farmer. Thus
present project will be helpful to farmers in order to augment the
crop yield and sustain the soil fertility, identify an effective
and low cost fertilizer level technique for maize and substitute
N-fertilizer with leguminous crops as an organic source.
