The impact of different rates of sulfur-containing humic acid was studied on yield and nutrient uptake of the fruits of olive “Zard” three-year-old trees in a trial based on a Randomized Complete Block Design with three replications in Shariati College of Tehran, Iran. The studied treatment was sulfur-containing humic acid at four rates of 0, 20, 25 and 30 kg⋅ha−1, which was applied at two stages. The highest fresh weight, dry weight, chlorophyll b, carotenoid, N and Cu contents were related to humic acid rate of 20 kg⋅ha−1. The highest fruit length, chlorophyll a and total chlorophyll were observed in control. The highest K, Fe and Mn contents were obtained from plants treated with 30 kg⋅ha−1 humic acid. Plants treated with 25 kg⋅ha−1 exhibited the highest P and Zn contents. All in all, the application of sulfur-containing humic acid at different rates had favorable impacts on quantitative and qualitative traits of olive fruits.展开更多

The first coal was exhausted from Mine Plant 2 in 1968. The most used method of mining so far in this area has been strike longwall mining with controlled caving. Due to extensive changes in the surface, which occur as a consequence of deep mining by the method of longwall mining with controlled caving, it is not possible to use this method in densely populated areas. At the present time, therefore, the trial operation of a new mining method called room and pillar is carried out. The method was chosen with the aim to minimize subsidence and deformations of the surface. The room and pillar mining method has never been used before in the conditions of the OKR, therefore it is necessary to prove the real effect of mining by this method on the surface. For this purpose, a surface observation station was designed, consisting of 36 surface points. The position and height of all points of the observation station is determined in stages three times a year.展开更多

The aim of this work was to evaluate the physical, physiological and sanitary quality of wheat seeds from plants that received non-selective herbicide application at pre-harvest. For this, the treatments were applied on pre-harvest culture. A completely randomized design was applied. We use the herbicides (glufosinate-ammonium, glyphosate and paraquat), phenological stages of herbicide application (Z-83, Z-85, Z-87, Z-92) and additional treatment (without application). The routine tests that express the physical, physiological and sanitary integrity of seeds were evaluated. For herbicide treatments, there was an 8% and 26% reduction in germination under laboratory conditions for BRS Parrudo and Sinuelo, respectively. Soil emergence was 14% higher for the control treatment, not statistically different for the Z-87 and Z-92 stages and also for the herbicides glufosinate-ammonium and glyphosate for both cultivars. The application of non-selective herbicides on wheat pre-harvest impairs the physical and physiological quality and promotes faster deterioration. Vigor is reduced under stress conditions by cold test and accelerated aging. There is no influence on seed sanity.展开更多
