Abstract : Nitrogen use productivity and life cycle of root knobs in horse feed after various mineral treatment and soil development practices were examined. Field preliminary was directed in the Organization of Scrounge Yields, Pleven, Bulgaria on filtered chernozem subsoil type and no water system. The following medicines were tried: I) for preparation as pursues: N0P0K0 (control); N60P100K80 (an acknowledged innovation); N23P100K35 (nitrogen was connected 1/2 in first year of developing and 1/2 in third year); N23P100K35 (nitrogen was provided pre-planting); N35P80K50, and Amophose - 250 kg/ha, determined at treating rates N27P120K0; ii) for soil development as pursues: soil losing 10-12 cm, furrow at profundity 12-15 cm, 22-24 cm (an acknowledged innovation), 18-22 cm and 30-35 cm. It was discovered that dirt development and mineral preparation had impact on nitrogen use productivity and life cycle of root knobs in Hay. Nitrogen use effectiveness was observed to be most astounding at N23P100K35 and furrow at the profundity of 22-24 cm. Life cycle of root knobs was the longest at N35P80K50 and furrow at the profundity of 18-22 cm. The better root mass to knob number proportion was found at N23P100K35 and furrow at the profundity of 22-24 cm.

Abstract : Some development parameters of pea (cv. Pleven 4) and vetch (cv. Obrazets 666) after treatment with natural manure were contemplated in a field preliminary completed at the Organization of Rummage Harvests, Pleven, Bulgaria. Humustim as natural compost was connected through presowing treatment of seeds, treatment during vegetation and blend between both, at various dosages. Proportions of over-the-ground weight to root framework weight, over-the-ground tallness to root framework length, just as explicit root length were resolved. It was discovered that the development factors of plants were decidedly impacted by natural manure. The over-the-ground weight to root framework weight proportions of pea ran from 4.80 to 6.29 and was higher than vetch. Over-the-ground tallness to establish framework length proportion in pea extended from 6.95 to 7.93, and in vetch from 5.30 to 7.39. The utilization of natural compost at the portion of 1.2 L/t and treatment during vegetation brought about better execution of root framework and explicit root length was 78.6 for pea and 84.3 for vetch

Abstract : Treating the soil of waste plant materials and its utilization in agribusiness and scene locales is a natural amicable method for lessening waste material and rationing the earth. In this point of view, we have stepped up to the plate at the Dubai based Worldwide Community for Biosaline Horticulture to compost the plant-based waste material (yard cuttings-grass) to compost. The material was vaccinated with a consortium of microorganisms prompting the arrangement steady and develop fertilizer with high natural issue (38%). So as to direct seed germination tests, fulvic corrosive was separated from the manure. A pot investigation was led over a time of 30 days in the green house to think about the impact of fulvic corrosive on the seed germination, and plant development of Prosopis cineraria (L.) druce (Ghaff) and Acacia tortilis (Forssk.) Hayne. Seeds of the two trees were treated with fulvic corrosive at 0.5% and 1% focuses water treatment was utilized as control. By and large seed germination and biomass were expanded at the two rates of fulvic corrosive application, be that as it may, an articulated increment was found in seed germination when fulvic corrosive was utilized at 1.0% (Prosopis cineraria 27%; Acacia tortilis 20% expansion over control). So also, biomass (shoot and root) of A. tortilis and P. cineraria demonstrated an expansion of increment 34% and 94% individually

Abstract : One of the most central procedures that assume an extensive job in lessening the centralization of overwhelming metals during estuarine blending is flocculation. Not exclusively does such a procedure cause a gigantic level of metals to come into the particulate stage, yet in addition it gives abundant supplements to the amphibian life. In the present examination, effect of such factors as saltiness, pH and DO on flocculation of Cu, Zn, Pb, Ni, Album and Mn all through blending of Chaluse Stream with Caspian Ocean is explored. The pattern of flocculation of Pb (24.32%) < Zn (24.38%) < Album (40.00%) < Cu (64.71%) < Ni (68.00%) < Mn (76.47%) uncovers that among the considered components Mn and lead experience least and greatest flocculation at assorted saltiness systems, individually. Additionally, flocculation rate of contemplated metals varies somewhere in the range of 24.32 and 76.47 percent. It is fascinating to take note of that quite a bit of metal flocculation happens at the very lower (under 2 ppt) saltiness systems

Abstract : This examination was centered around evacuation of different parameters in paper plant profluent utilizing a technique called bioremediation by Azolla caroliniana. The test examinations have been completed utilizing Azolla caroliniana for directing the sorption ponder with different weakening proportions (2, 4, 6, 8, and 10), pH (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). The greatest expulsion level of TDS, Body and COD in a paper plant emanating was acquired at the ideal weakening proportion of 6, pH of 8 and biomass of 800 g. The consequences of this examination showed that the most extreme evacuation level of TDS, Body and COD in a paper plant emanating was 82.3 %, 88.6 % and 79.1 % individually. Likewise, the investigation concentrated on take-up of TDS, Body and COD in paper plant profluent by Azolla caroliniana through bioaccumulation factor and translocation factor. The aftereffects of bioaccumulation factor uncovered that TDS, Body and COD in paper factory emanating were adsorbed by Azolla caroliniana. The aftereffects of translocation factor uncovered that the underlying foundations of Azolla caroliniana translocate the TDS, Body and COD in a paper plant emanating to the shoots of Azolla caroliniana. From the outcomes, this examination presumed that bioremediation by Azolla caroliniana could be adequately utilized for evacuating TDS, Body and COD in a paper plant profluent. This investigation additionally proposed that Azolla caroliniana might be utilized for expelling different contaminants, from paper plant emanating, yet additionally from some other mechanical effluents
