Cotton as one of the important and strategic agricultural products is the raw material for the textile, food and livestock industry. In addition to, it plays important role in foreign exchange earnings and employment in agricultural, industrial and trade sectors. Since the cultivation area of this crop, particularly in Golestan province that is famous for cotton production and the land of white gold, faced with a decreasing trend in recent years, thus this study investigates the factors affecting of cotton cultivation area in the Golestan province based on Nerlove Partial adjustment methods and the time series data in 1983-2012 periods with the analysis of the cultivation area in province and Country level. The results indicate that the relative price of cotton to wheat, cotton acreage with one lag, cotton yield with one lag, wheat acreage (competitive crop) and government effective protection rates have a significant effect on cotton acreage in Golestan province. All variables except for wheat acreage have a positive effect on cotton acreage. The results also show that 34 percent of the cotton acreage was due to the behavior of farmers in the previous period and with appropriate protection policies, about 66 percent of the gap between desired and actual cultivation will be reduced.

In order to evaluation of drought stress on seed germination and seedling growth of cotton cultivars, a survey was carried out in two phases (under laboratory and green house conditions) in Cotton Research Institute. Researches were carried out in factorial experiment on CRD, with four replications. Factors were drought stress and cultivar. In germination test and greenhouse condition phases, water stress levels were included: 0, -0/4, -0/8 and -1/6 MPa (for germination test with D-Manitol application) and non-water stress, mild water stress and high water stress (75, 15 and 5 % of relative soil water content, respectively) were considered for greenhouse phase after 35 days after planting date. Cultivars were contained: Sahel, Tabladilla, Siokra and No-200 as Tetraploid cultivars and Hashem Abad and Kashmar as Diploeid cultivars. Results of seed germination test indicated that the lowest germination percent in 4th day, total germination percent and germination velocity was occurred under -1/6 MPa water potential. Germination rate was not different in 7th day and total germination percent between 0 and -0/4 MPa levels. Siokra has the highest total germination percent, germination velocity. Results of greenhouse experiment, drought stress decreased leaf fresh weight significantly. Plant height and total leaf chlorophyll was affected by first and second stress levels equally but the highest value of total chlorophyll was formed under high water stress level. In this part of study, total dry weight of seedlings has not shown any difference. Tabladilla has a good performance in compare to other cultivars under means of drought stress levels. Results suggested that germination percent in upper than -0/8 MPa water potential did not success in studied cultivars on farm and if it is forecasted a drought stress period in initial growth season after establishment, It is better to planting Tabladilla for cultivation.

A field experiment was performed to studying interaction effect of nitrogen levels and plant row spacing on yield and yield components of cotton vs. Golestan. After canola harvesting, treatments were arranged and planted by split plots in basic randomized complete blocks design with 4 replications. Plots were 4 nitrogen levels including 0, 50, 100 and 150 percent of recommended fertilizers amounts as main plots and 40, 60, 80 and 100 cm plant row spacing as sub plots. Before planting, fertilizer recommending was determined basis of soil testing in 0-30 cm depth. Results showed significantly increasing yield, plant height and vegetative and reproductive branch lengths. Decreasing plant row spacing decreased boll number per plant, plant height, vegetative and reproductive branch lengths and weed density per square meter so that the lowest boll number per plant, plant height, vegetative and reproductive branch lengths and weed density per square meter were obtained 40 cm plant row spacing. This treatment produced the highest total and first picking yield. On yield increasing, boll number per square meter had the more effect than boll number per plant because plant density increasing in area unit reduced boll number per plant, in contrast, plant density increasing in area unit increased boll number in area unit.

Water deficit is one of the known methods of irrigation in water scarce regions of the world. Use of every- other- furrow irrigation is the one of deficit irrigation techniques. A study was carried out to investigate the effects of deficit irrigation on cotton in split plot randomized complete block design in four replications during two years, in Bakhtajerd research station (Darab). Main Plots contained five treatments: 1) Irrigation of all the furrows in ever irrigation as normal irrigation; 2) Constant every other furrow irrigation; 3) Variable every other furrow irrigation; 4) Once normal irrigation and twice every other irrigation; 5) Twice normal irrigation and once every other irrigation. Subplots contained two levels of plant growth regulator (pix) by spraying. Plant properties such as cotton yield, number of boll, boll weight, earliness, harvest index and water use efficiency were evaluated at the end of growth season. The results of combined mean comparison by Duncan’s test indicated that deficit irrigation decreased cotton yield in all irrigation levels in comparison with normal irrigation. Pix usage didn’t show significant effect on cotton yield. Impact of pix application on number of boll was negative, although increased boll weight and harvest index significantly. Also, Pix increased the earliness and strengthen of crop against water shortage as well. Deficit irrigation technique proved increment water use efficiency in the second and fourth irrigation levels by 20.2% and 14.03%, respectively.

Cotton is qquantitative parameters by which multiple genes can be controlled. Increasing the yield and quality of cotton is important factors that affected by genetic and environmental factors. Factors affecting on yield and earliness, and genetic and environmental influences are determinate that can be useful in breeding of new varieties. In this study 20 genotypes of crop species barbadense and hirsutum were evaluated in a randomized complete block design in 2013. The results showed that Bakhtegan and Barg pahne barg ghermeze were the heaviest 30 bolls weight (200.5 and 202.4 gr respectively). Giza and Termez14 and barbadense ( all of the Gossypium barbadense) were the lowest 30 bolls weight (105.9, 108.3 and 111.5 gr respectively). The yield significant positive genetic correlation was observed with numbers of monopodial branches, largest monopodial branch length and 30 bolls weight on the surface of one percent. And also, Yield had significant negative genetic correlation with the height, numbers of sympodial branches on the surface of one percent. Earliness had Positive and significant genetic correlation with height, number of sympodial branches, sympodial branch length and boll numbers. Meanwhile, earliness showed significant negative genetic correlation with the numbers of monopodial branches, largest monopodial branch length, 30 bolls weight, and yield.

In recent years, with the increase in cultivation of canola, Cotton Research Institute of Iran began studies to identify appropriate varieties that suitable for planting after canola harvesting. In these studies, the earliness varieties with high yield and good fiber quality is emphasized.Because the Cotton plant needs a lot of heat and light to complement the growth period. So in delayed cotton planting, appropriate growing season is limited. Therefore, in addition to selecting appropriate cultivar, success key in the cultivation of late, are good farm management, especially management of irrigation. Because in delayed cotton cultivation create the balance between vegetative and reproductive growth with irrigation management is very important. Production function or water-yield relationship is appropriate index to optimize water use in cotton cultivation. Cotton production function is different at late planting comparison with normal planting date. For this reason, this experiment was conducted to determine the production function of cotton in the canola-cotton system. After seedling emergence, land was divided into 3*3 m. In middle of each section was placed a tripod and cach can for collecting Irrigation water. The relationship between water-yield of Armaghan and Golestan varieties were determined in the form of and equation respectively. Based on the production function, the highest yield of Armaghan and Golestan varieties as well as 3909 and 3973 kg/ha can be obtained with 1739 and 1832 m3/ha water consumption.

The cotton picker harvesting machines are expose to the limitations as follows: Inappropriate space between the planting rows harvester head, utilizing the deciduous before harvesting; high prices, being of imported cotton harvesting machine and exit the currency of the country; the small size of the most farms and the cultivation of non-linear and non-acceptance negligible loss machinery by the farmers. Therefore, it is necessary to design and developed a cotton-harvesting machine that it can apply under the afore-mentioned limitations. For this purpose, a self-portable machine with three-wheel designed. It has a special harvester unit. Picker unit have made with the number of bars such as the finger. It can rotate by an electrical motor. This unit moves by the worker between the bushes and pick the cottons. Cottons can be picked by harvester unit and then transmit them to the reservoir via transmission tubes, with the two mechanisms, suction and blow. The gathered cottons inside the big gunnydischarge at the end of the farm. The objective of this study was design, construction and evaluation of a semimechanized cotton picker-harvesting machine. In the evaluation of this machine, compared to the traditional cotton harvesting (manually). This machine designed first by the SOLIDWORKS software, and then made. To evaluate of this machine and its comparison with the manual method, the two varieties of cotton, Golestan and Khorshid harvested in four rows at the length of 36 m, with three replications. The evaluated properties were field capacity, field losses, impurityamount and fiber length. The experimental design carried out based on the randomized complete block design with the two factors, harvesting method at the two levels (manually as control and semi-mechanized machine) and variety at the levels, Golestan and Khorshid. The test results and evaluate showed that the field capacity of cotton harvesting of this machine was 18/7% more than the handpicked. Moreover; the fiber quality not only does not reduce, but also in some cases, such as the fiber length increased and showed significantly at 5%level with this machine, when compared to manual harvesting method. Increase at about 3 percent in purity and significant increase in the fiber length at 5 percent level was the other result of this machine.
