Read More AbstractIntroductionConcurrency of cereals late-season irrigation with early irrigation of sugar beet season and lack of water resources at this time, has made some farmers to delay sugar beet cultivation. The planting date plays a key role in growth, quality and yield of sugar beet. Delayed cultivation leads to reduced sugar beet yield. In late cultivation of sugar beet (Beta vulgaris L.), the use of nitrogen fertilizer and growth promoting bacteria can be of great importance in accelerating growth and compensating for lost time. The aim of this study was to find a sustainable way to increase the growth rate of sugar beet in delayed cultivation, so as to compensate for the delayed growth season as possible. Materials and MethodsThis experiment was conducted as a split split plot in a randomized complete block design with 6 replications on Arta sugar beet cultivar at the Research Farm of Ferdowsi University of Mashhad in 2018. The factors included planting date (regular and delayed sowing) as main factor, nitrogen fertilizer (based on recommendation and 25% less than recommended) as sub-factor and Nitrobacter application and non-Nitrobacter were considered as sub-factors. Results and DiscussionThe results showed that the inoculation effect of Nitrobacter on leaf area, total dry matter, root yield and sugar content increased by 13, 20, 9 and 8 percent, respectively. Also, Nitrobacter treatment had the least effect on the amount of sodium, potassium and nitrogen of root in both sowing dates. For delayed planting date, using nitrogen fertilizer plus growth promoting bacteria can offset the delay in planting date. Therefore, this recommendation can reduce water consumption by reducing sugar beet growing season and reduce fertilizer use. It seems that the combination of chemical and biological fertilizers is effective on sugar beet delayed cultivation in order to compensate for lost time. ConclusionThe combination of chemical and biological fertilizers is effective on sugar beet delayed cultivation in order to compensate for lost time.

Read More Background and Objectives Organic fertilizers are derived from animal matter, human excreta or vegetable matter. (e.g. compost, manure). Organic fertilizers are carbon-based compounds that increase the productivity and growth quality of plants. Organic fertilizers preserve food cycle; reduce pollution and remediation of soil physicochemical properties and stabilization of plants in soil. Use of these organic fertilizers ensures that the food items produced are free of harmful chemicals. As a result, the end consumers who eat these organic products are less prone to diseases such as cancer. In addition to the on-farm production possibilities of organic fertilizers, organic fertilizers help in maintaining the soil structure and increasing its nutrient-holding capacity. Organic fertilizers are easily bio-degradable and do not cause environmental pollution. On the other hand, chemical fertilizers contaminate both the land and water, which is a major cause of diseases for human beings and is the force behind the extinction of a number of plant, animal, and insect species. Material and Methods In order to investigate the effect of organic fertilizers (vermicompost, compost and manure) on morpho physiological characteristics of Petunia hybrida an experiment based on a completely randomized design with three replications was conducted at the Ferdowsi University of Mashhad.Irrigation treatments consisted of three levels (100 % of field capacity by irrigation at a rate of 360 cc (D1), 50% of field capacity by as much as 180 cc (D2) and 25 % of field capacity by as much as 90 cc (D3 )), and four fertilizer treatments (control, compost, vermicompost and manure). Some traits such as stem fresh weight leave fresh weight, flower fresh weight, length, diameter and number of flowers, SPAD index, leaf area, relative water content and membrane stability index were measured. Results The results showed that effects of the treatments on traits such as flower fresh weight, length, diameter and number of flowers, SPAD index, relative water content and membrane stability index were significant at 1% level. The interaction of two factors on traits such as stem and flower fresh weight, flower number, leaf area, leaf fluorescence, relative water content and membrane stability index was significant. Thus the weight of a single flower per plant increased with the application of vermicompost fertilizers, compost and manure, respectively, 16/26, 65/9 and 40/8% over control at 100% capacity. Irrigation with treated manure at 25% field capacity (D3) increased length of flower over 14% compared to control. In 50% of field capacity (D2) with vermicompost in the context of the membrane stability index was 62% which, compared to control treatments at the same level of irrigation, was increased by 67%. Use of manure and vermicompost seems to improve adverse effects of drought stress. Discussions Manure and vermicompost improves soil aeration, enriches soil with micro-organisms (adding enzymes such as phosphatase and cellulase), Enhances germination, plant growth, and crop yield and also improves water holding capacity.
