A field study was conducted to evaluate the effect of different seed rates and nutrition on the yield of wheat; at Agronomic research area, University of Agriculture Faisalabad during 2008-2009.The experiment was laid out in a split plot design with three replications. The treatment comprises four different fertilizer level F0( Control no fertilizer), F1 ( 100-115-67 NPK kg ha-1 ), F2 ( 115-130-82 NPK kg ha-1) and F3 ( 130-145-97 NPK kg ha-1) with three different seed rate S1 (100 kg ha-1), S2( 125 kg ha-1), S3( 150 kg ha-1).Wheat variety Shafaq-2006 was planted. Results showed that different fertilizer level and seed rates affected significantly the various parameters under study especially ,plant height, spike length, number of spikelets spike-1, 1000-grain weight, economical yield and harvest index. Among the seed rates, 125 kg ha 1 produced significantly the highest grains yield (4.30 t ha-1) followed by 150 kg ha 1 seed rate (3.87 t ha-1).Regarding nutrition, F2 (115-130-82 NPK kg ha-1) fertilizer level produced significantly the highest grain yield (4.85 t ha-1

Introduction
Wheat (Triticum aestivum L.) is the most important cereal crop in the world, and is a staple food of about one third of the world’s population including Pakistan. In Pakistan wheat is the most important cereal crop both in terms of production and area under cultivation.Wheat was cultivated on an area of 9062 thousand hectares, showing an increase of 5.9 percent over last year’s area of 8550 thousand hectares. The size of wheat crop is provisionally estimated at 23.4 million tons (Government of Pakistan, 2009).
In Punjab (Pakistan), there are predominantly cotton-wheat-cotton and rice-wh...

Kingsolver indicated that these wheat crops are undergoing natural selection. More specifically, there are four conditions that must be legitimate for natural selection to engage in a given
The country at the time was in the deepest and soon to be longest-lasting economic downturn in the history of the Western industrialized world and this caused years of over-cultivation of wheat, because “during the laissez-faire, expansionist 1920’s the plains were extensively and put to wheat - turned into highly mechanized factory farms that produced highly unprecedented harvests” (Worster 12). The farmer’s actions were prompted by the economic decline America was facing. With the economy in a recession, farmers were looking for a way to make a living and in 1930 wheat crops were becoming very popular. In 1931 the wheat crop was considered a bumper crop with over twelve million bushels of wheat. Wheat was emerging all over the plains.
Three substances mainly make fertilisers: nitrogen, phosphorous and potassium. Their percentage in the solution will change the effectiveness on a determinate plant; for example is recommended to use high proportion of nitrogen fertilizers during the spring growth of spurts. The fertilisers can be spitted in two categories: organic that contains a low level of nitrogen, phosphorous and potassium and aren’t toxic to the environment and synthetic that are made by a high concentration of the three substances and can be corrosive to the environment if are overused.
The grain sorghum variety planted must be resistant to charcoal rot and sugarcane aphids. The yield goal for the wheat crop this year is 30 bushels to the acre. We believe this is an accurate assessment because this field was continuous wheat and it is dryland. Continuing into field two we decided to get a jump on the rotation of wheat, fallow, sorghum. This 80-acre field was a continuous wheat field so we wanted to let it rest.

There are 7.79kg/tom of N-fertilizer, 0.0kg/ton of P2O5, and 14.41 kg/ton of K2 O-fertilizer that are applied to FFB on average. This was an average from 9 months at the nursery stage and 25 years at the field stage. Glyphosate and paraquat are used as herbicides. Herbicides are applied on average about 1-3 times per year at around 1.8-3.1 hg per ha per ton for glyphosate and .6-1.2 per ha per time for paraquat for the specific study site. Seeds of oil palm are applied at 168 kg/ha (Pleanjai and Gheewala).
With the rapid growth of our global population pouring into the next millennium, we will witness an ever-growing hunger rate around the world. That is unless we call for a revolution on the global scale. The Green Revolution which already sprouted in the early part of the century only need to add a bit more momentum and we will see a bright future for the human race, a future without hunger and starvation ¡V hopefully.It is becoming increasingly difficult for the planet to support its overwhelming population. And since the amount of arable land available is becoming scarce, we must seek ways to dramatically improve crop yields of existing cropland.
We used wheatgrass were 40 wheatgrass seeds, two empty pots, soil, and water. We first added soil for both pots and 20 wheatgrass seeds in each pot. My partner and I decided that we label pot one experiment which is “sugar and water” and pot two control which is “water” only. The experiment was for almost four weeks we had to make sure both get the same room temperature and water, so we can see the results after this amount of time. Both pots had same room temperature so both can have the same amount of sunlight also, the same amount of water which is a glass of water from the sink once a week. In the experiment pot we added a glass of water with one teaspoon of sugar and the control pot glass of water. Every week we used to see both pots grow almost the same. At the end of the experiment, my partner and I measured the length for both plants and we recorded the average for each plant, so we can know the rate of growth
Throughout the history of the human race there have been a great number of crops that were discovered, planted, and over time domesticated. Wheat in the Middle East, rice in Asia, and rye in Eastern Europe are all some of today’s staple crops that feed millions every day. Crops like these make up over 50% of the world’s total food supply. However, the third most eaten crop in the world is maize, or corn, which provides 21% of human nutrition. Today maize feeds millions across the world, but its history is different from the others.

In south part of China, where water resources are plentiful, is suitable to plant rice which need to be planted in water. In addition, temperature in south is warmer than north, and it will not drop under zero Celsius in autumn or winter, which means farmers can plant seed of rice in the field in autumn and receive the second time of harvest in winter. Because of the fast grown speed of rice and the suitable weather for it, southern residents eat more food made by rice. Take the traditional staple food in south as an example, traditional staple food in southern China are rice, which is popular in most of province in the south, and rice noodle, which are traditional food of Yunnan province and Guangxi province. The northern China, in other hand, has more staple food made by wheat. Compare to rice, wheat has a slower grow speed with a larger production, which perfectly fitted the weather in north part of China, whose weather is totally differ from south. In ate autumn and winter, temperature in northern China never go above zero, and people had to stay at home in the past. Based on this background, wheat is an excellent material to make staple food, for its large production, and the staple food made by it are easier to preserve than rice. Therefore, northern residents eat more wheat; for example,
Barley is a very important grain in the world today. It is very versatile in every way. It has been well adapted through its evolution. It has a very mysterious and much debated beginning. Now however, barely has become well known and so have its many uses. Barley, which is of the genus Hordeum, is a cereal that belongs to the grass family Poaceae. Barley has many different varieties. The most common is Hordeum vulgare, which is a six-rowed type of barley that has a spike notched on opposite sides with three spikelets on each notch. At each notch there is a flower or floret that later develops into a kernel. Hordeum distichum is a two-rowed type of barley that has central florets producing kernels and it has lateral florets that are sterile. Lastly there is Hordeum irregulare which has fertile central florets and different arrangements of sterile and fertile lateral florets. This is the least cultivated species of the three main forms (2).
This lesson is designed to review and reinforce a few important concepts about plants (e.g. Needs, parts, sequence of planting) and to also guide the students through applying a few scientific inquiry (e.g. Making observations, experimentation, discussion, reflection, reporting results etc.). The students have previously planted corn and bean seeds and today’s lesson has provided the students a chance to see the results of the planted corn and bean seeds. Additionally, seeds have been planted under and growing under the following conditions: without water, and without soil. The students see the results of these seeds planted under these conditions for the past week. Two plants in particular have already been grown their growth has been
