In order to study the effect of variety, density and weeds interference on morphophysiological and qualitative traits of cotton, a factorial experiment was conducted in a randomized complete block design with three replications at Research Farm of Islamic Azad University, Birjand Branch in 2015. The research factors consisted of two varieties (Philistine and Khordad), two density levels (14 and 28 plants. m²) and four levels of weed interference (weed free in the whole period, interference up to 40, 60 and 80 days after emergence of cotton). The results showed that Khordad variety in comparison to Philistine variety had superior significant 17.9 and 15.1 %, in traits of seed yield and oil yield respectively. Also, increasing density from 14 to 28 plants per m², seed yield and oil yield significantly were increased by 90 and 100.3%, respectively but number branches of main stem and stomatal conductivity significantly were decreased by 28.6 and 10%, respectively. With increasing the length of period of weeds interference up 80 days, number branches of main stem, seed yield, oil yield and oil percent significantly were decreased by 61.3, 94, 96.5 and 53.1%, respectively. In general, based on the results of this research, cultivation of variety Khordad with density of 28 plants per m² and weeding in the whole growth period is suitable for maximum of oil yield in cotton cultivation in Birjand region.

Abstract Deterioration of seeds is one of the important factors in reducing seeds vigor and limit germination. In order to investigate the effect of gibberellic acid hormone on recovery of seeds, and seedling growth in Varamin cotton seed. The experiment was done randomly three times. The experimental sets consisted of two decline levels (48 and 96 hours) with witness and 2 dense levels of gibberellic acid hormone (500 and 1000 PPM) with witness, and the treatment of gibberellic acid hormone was completed in 3 styles (before deterioration, after deterioration and before and after the deterioration. The results showed that the combination of treatments at 500 PPM without deterioration indicated that plumule length, root length, dry root weight, the amount of seed reserves, efficient use of reservoir seed, seed fraction of the resources consumedhad the best treatment. In the prime applying experiment before deterioration, in 500 PPM density with rate and uniformity of germination, D10, D90, plumlule length, root length, dry root weight, dry plumule weight, usage amount of reserves, effective use of resources, consumption and seed fraction, had the bestresult; and at 1000 PPM level the percentage of germination, demonstrated the highest improvement. Finally, in general we can say that gibberellic acid can recover deteriorated seeds.

Cotton is the most important fiber crop in Iran and as well as the world. The acreage of cotton is about 80,000 ha in Iran. The present study aims to determine the parameters of the SSM-iCrop2 model and evaluate the ability of the model to simulate cotton growth and yield in different regions and environmental conditions of Iran. Different aspects of crop growth are organized as sub-programs including phenological development, leaf area changes and dry matter production and distribution. Soil water balance sub-program is entered in the model to simulate changes in soil water and determination of stress severity. Simulation by the model is done on a daily basis and requires data related to atmosphere, soil and crop management. The model was tested for Iran conditions. To estimate the coefficients and evaluation of the model, data obtained from experiments conducted in various areas of the country were used. The model was evaluated using independent data following estimation of genetic parameters. The results indicated acceptable efficiency of the model in prediction of daily simulation including days to maturity (RMSE=8.4 day, CV=6.5 %) and seed cotton yield (RMSE=56.6 g/m2 and CV=13.9 %) for parameterization and seed cotton yield (RMSE=50.4 g/m2, CV=12.8 %) for evaluation. Also, the results showed that RMSE and CV values for simulation of yield, Evapotranspiration, and used water were respectively (77.6, 12.9%), (150.3 and 16%) and (178.5 and 19.6%) in major cotton production areas of Iran. These results indicate that estimates for variables are acceptable.

In order to investigate the effect of different methods, levels and salinity of irrigation water on cotton, a two-year experiment was carried out at the Hashemabad Cotton Research Station in Gorgan city. The experiment was performed in a randomized complete block design with three replications. So, four salinity levels of irrigation water (1, 4, 8, 12 dS/m) as main factors, four different levels of irrigation water (33, 66, 100 and 133% of water requirements) was considered as the first factor and two irrigation methods (complete irrigation and Partial Root Dry irrigation/PRD) were considered as the second factor. The results showed that compared to control, cotton yield decreased by 41%, 22% and 19%, in 12, 8 and 4 dS/m salinity, respectively. The water use efficiency was reduced at rate of 30, 18 and 16 percent. As the salinity of irrigation water increased, the average weight of the boll, fiber index, earliness and the fibers decreased significantly. As the moisture level increased, the yield of cotton, average boll weight, the number of seed in a boll and the number of bolls increased significantly. In additional the water use efficiency of the 133, 100 and 66% treatments compared to 33 percent decreased by 32, 16 and 10 percent, respectively. The cotton yield under133, 100 and 66% treatments decreased by 32%, 16% and 10%, respectively, compared to the 33% of the water requirement. Although PRD reduced crop yields by 15 percent compared to full irrigation treatment, but the water use efficiency increased by 36%.

In order to investigate the effect of growth regulators on a number of morphological characteristics of cotton cultivars, the present research was conducted as a factorial experiment in a randomized complete block design with 3 replications at Hashemabad Cotton Research Station, Gorgan in 2016 and 2017. Factors included growth regulators treatments with 6 levels (control, benzyl adenine, abscisic acid, salicylic acid, brassinosteroid, and cycocel) and three cotton cultivars of Golestan, Kashmar, and Shayan. Growth regulators affected most traits. Cycocel produced the highest number of bolls per plant (13.4) and abscisic acid reduced the number of bolls by 25% compared to the control. Salicylic acid increased, and abscisic acid and cycocel decreased the distance from the first sympodia to the ground. The highest number of fifth sympodia nodes, respectively, with an average of 7.17, 7.09 and 7.07, was allocated to foliar application with salicylic acid, brasinosteroid and cycocel, and the lowest with 6.07 and 6.13 belonged to abscisic acid and benzyl adenine. Overall, salicylic acid and benzyl adenine were able to increase the internodes length and abscisic acid and cycocel to reduce it. Therefore, with the aim of selecting cultivars with higher boll number, it is possible to use growth regulator of brasinosteroid or cycocel, and Golestan and Shayan cultivars, but to select a higher early maturity percentage, salicylic acid or cycocel, and Kashmar and Shayan cultivars can be used. In general, it is possible to recommend the cycocel growth regulator and Shayan cultivar.

This study was carried out to investigate persistency of four insecticides (thiodicarb, indoxacarb, proclaim fit and lufenuron) on cotton plants and their toxicity against Trichogramma brassicae .Cotton seeds were sown under greenhouse condition and cotton plants were sprayed with insecticides . Cotton leaves were removed at one-day intervals and were kept in a rearing container with female parasitoids and host eggs. Mortality and sublethal effects of insecticides were recorded every day and their toxicity and persistency were categorized according to the International Organization of Biological Control standard. Results showed that toxicity (with up to 100% mortality) and persistency (>17 days) of thiodicarb was higher than other insecticides and was categorized as a “harmful” and at least a “moderately persistent insecticide. Indoxacarb with up to 52.8% mortality, 62.8% reduction in parasitism and 7 days persistency, was classified as a ”harmful” and “slightly persistent” insecticide. Proclaim fit with up to 37.3% mortality, 47.4% reduction in parasitism and 6 days persistency, was classified as a “moderately harmful” (Group 3) and slightly persistent insecticide. Lufenuron with up to 2.68% mortality, 60.69% reduction in parasitism and 3 days persisitency, was classified as a “slightly harmful” (Group 2) to ”moderately harmful” and short-lived (group 1) insecticide. In conclusion, because of high toxicity and long-term persistency, thiodicarb is not recommended to use in cotton field against cotton bollworm, and a 7, 6 and 3 days “waiting period” was required, respectively between spraying with indoxacarb, proclaim Fit and lufenuron and mass releasing of T. brassicae in cotton fields.

This study aimed to determine the yield stability and adaptability and also analysis of the effect of genotype-environment interaction of 15 cotton genotypes in four regions of Birjand, Shiraz, Karaj, and Kashmar in randomized complete block design with three replications. Combined analysis of variance showed that the effect of environment was significant at the 5% level probability and the effects of genotype and genotype-environment interaction were significant at the 1% level probability. Based on AMMI model only the first main component of the interaction effect was significant and explained about 63% of changes related to the interaction of genotype with the environment. According to the biplot of average yield of genotypes and environments and first main components of interaction in the AMMI model, genotypes of DeltaPin 25, Oltan, SP731, Varamin, SB35, and Shirpan 603 had a nearly zero interaction, among them SB35 and Varamin genotypes were due to yield higher than the total mean as high yield stable genotypes. Based on graphical biplot analysis, the environments studied were located in two mega-environments and consistent genotypes were identified in each mega-environment. The first mega-environment included Birjand and Shiraz and Bakhtegan and Mehr genotypes had the most specific adaptability with them. N-200 genotype had the highest specific adaptability with Karaj and Kashmar (second mega-environment). The ideal genotypes and environment biplots, respectively, introduced SB35 and Birjand to the nearest genotype and environment to the most ideal condition. The results confirm the high effect of genotype-environment interaction on the yield of cotton genotypes.

One of the reducing methods of salt stress damage effects is useing substances that increase seed germination and plantlet establishment in salt stress conditions. In this research potassium and glycine effects were evaluated by randomized complete block design with four replications at Agriculture and Natural Resource Research Stations of Kashmar and Feizabad in none salt and salt conditions during 2015 and 2016. Treatments were such as: 1-Control (spray with water) 2- Folar application (FA) of potassium 1% at 50 percent of flowering and boll set stages (50% of F&B) 3-(FA) of glycine (100Mm) at (50% of F&B) 4- Seed priming with glycine 1% (SPG) 5- (FA) of potassium 1% and glycine 100Mm 6-(SPG) and (FA) of potassium 1% 7- (SPG) and (FA) of glycine and 8- (SPG)+ (FA) of potassium and glycine. Results showed Seed priming and foliar application of potassium and glycine significantly increased number of plant per area unit at salt stress conditions. Results also showed experimental treatments increased leaf relative water content and significantly reduced shedding of flower and boll per plant in comparison with control. Consequently, boll number per plant and seed cotton yield were significantly increased following foliar application of potassium and glycine. Therefore, seed priming with glycine and foliar application of glycine and potassium at 100 mM and 1% respectively increase plant growth and seed cotton yield under salt stress conditions.

To investigate the effect of winter cover crops on weed dynamics, growth and yield of Cotton Var. Golestan, an experiment was conducted in 2017-2018 at research farm of Gorgan University of Agricultural Sciences and Natural Resources as split-block with three replicates. Treatments included cover crops at seven levels of barley, rye, hairy vetch, Indian mustard, arugula, clover and cover crop-free control under weeding and non-weeding conditions. Leaf area index and dry weight of cotton decreased significantly under non-weeding conditions, The results indicated that lack of weed control led to decrease in bolls per plant, boll weight and lint yield. The highest and lowest lint yiled was observed in hairy vetch with 5035 Kg.ha-1 and barley and arugula treatments with 2261 and 2403 Kg.ha-1, respectively. The highest lint yield in weeding conditions was observed in the treatment of hairy vetch with 5035 Kg.ha-1, which was not significantly different from the berseem clover treatment. The lowest lint yield in weeding conditions was obtained in barley and arugula cover crops treatments with 2261 and 2403 kg.ha-1, respectively. Due to the proper control of weeds in these treatments, it seems that the occurrence of allelopathic effects due to the decomposition of the residues of these two plants on cotton has been the cause of this reduction. According to the results, sowing cotton in hairy vetch and berseem clover residues and a supplementary management strategy such as weeding or application of herbicides at reduced rates is recommended for effective weed control.

Seed treatment with insecticide is necessary to protection of cotton seed from pests. Research was conducted in Randomized Compelet Block Design (RCBD) with 4 replication in 2013-2015 in Gharakhil agricultural research station at Mazandaran province, Ghaemshahr city and Karkandeh research station at Golestan province, Kordkuy city. This research were carried out with treatments included 1-control (no treatment) 2-seed cover with a mixture of cow dung and clay to 50% 3- Neem Azal T/S 1/5 % 4-Gaucho 5-7 gr/kg seed 5-Carboxin-Tiram 7-10 gr/kg seed 6-cover with liquid manure of cow urine. Intra and inter row spacing was 80×20 cm. Results showed that treatment of cotton seed with Gaucho was the best with high product yield and cotton seed emergence than other treatments. Neem Azal T/S was in the next stage in control of Thrips and cutworms. Highest number of aphids was in neem azal treatment and lowest number of aphids was in Liquid manure cow urine. Cow dung has the least effect on damping off and carboxin tiram treatment has the least damaged cotton plants. Use of animal fertilizers and natural ingredients in cotton seed disinfestation will help to reduction of the use of chenichals in pest and diseases of coton.
