A Thlaspi caerulescens (J. & C. PRESL) was used to study the effect of cadmium on the content of free amino acids and ability accumulation of Cd in ecotypes of this plant species. In pot experiment two ecotypes T. caerulescens were used: Ganges ecotype from France and Mežica ecotype from Slovenia. The plants were grown in soil (chernozem – Suchdol) spiked with NPK and three different concentrat...
Based on various characteristics of zeolite, its utilization in the manufacture of fertilizers with slow-release properties is possible. The objectives of this study are to characterize and utilized nitrogen, phosphorus and potassium (NPK) slow release fertilizer by using natural zeolite in Indonesia. In this research, zeolite was utilized as a mixture of Slow Release Fertilizer (SRF). Effect o...
Rapeseed (Brassica napus L.) is one of the oilseed crops in the temperate regions and is adapted to different climate conditions. This crop can have an important role in production of vegetable oil, and providing appropriate soil fertility can increase its seed and oil yield. In order to investigate the effect of N, P, K, Fe, Zn and Mn on seed yield and other agronomic traits of rapeseed, an ex...
The investigation entitled, “Integrated Nutrient Management in Bottle gourd [Lagenariasiceraria (Mol) Standl.] Variety Kashi Ganga on the Plant Disease Incidence,TSS and Economics under Malwa condition of Madhya Pradesh” was conducted during Kharif season year 2019-20 Department Horticulture, College Agriculture, Indore (M.P.). experiment randomized block design replicated thrice. There were 15...
این تحقیق با هدف ارزش گذاری اقتصادی عناصر غذایی اصلی خاک و با تأکید بر خاک جنگل های منتخب منطقه حفاظت شده شیمبار در استان خوزستان انجام شده است. در این پژوهش ابتدا با روش epm، میزان فرسایش تعیین و سپس مقدار هدر رفت سه عنصر غذایی مهم (نیتروژن، فسفر و پتاسیم) بر اساس اختلاف مقادیر عناصر غذایی دو تیمار شاهد و فرسایش یافته اندازه گیری شد؛ سپس ارزش پولی نگهداری عناصر غذایی خاک به وسیله پوشش جنگلی، ب...
Mercury (Hg) contents in ten chemical fertilizers were determined, and the effect of calcium superphosphate (CSP) on the uptake and translocation of Hg in corn seedlings was investigated by pot experiments. CSP was applied at the levels of 0, 66.7, and 133.4 mg P2O5/kg to Hg-treated (2 mg/kg) and untreated soils. CSP had the highest Hg content (5.1 mg/kg), followed by the NPK compound fertilize...
A plant growth promoting bacterial endophyte designated as AL2-14B isolated from the leaves of Achyranthes aspera L. was identified as Pseudomonas aeruginosa based on its phenotypic and physiological features, and 16S rRNA gene sequence analysis. AL2-14B had plant growth stimulating attributes including siderophore and indole acetic acid release, inorganic phosphate solubilization, along with n...
Plant production, soil quality, and a sustainable environment depend on climate change. Drought is multidimensional stressor that seriously affects plant production. The most sensitive to change the invasive goldenrod (Solidago canadensis L.), which has potentially high-value materials can be used develop novel approach controlling its spread. This study aimed evaluate impact of different appli...
The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two s...
Field experiments were conducted at Patuakhali Science and Technology University research farm during 2009 T. Aman season to investigate the effect of tidal submergence on potassium nutrition and yield of rice. The experiment included two levels of irrigation water sourcei) tidal water and ii) ground water, and three levels of fertilizersi) absolute control (no fertilizer), ii) NP (K omission),...
