A field experiment was carried out in the years 2008-2011 in China to assess the nitrogen metabolism enzyme activities and photosynthetic characteristics in stable-yielding stay-green rice (Oryza sativa L.) cv. Shennong196. The results showed that higher levels of nitrogen content, nitrate reductase activity, and glutamine synthetase activity occurred in leaves of cv. Shennong196 compared with cv. Toyonishiki (control). Leaf color of cv. Shennong196 was positively correlated with nitrogen levels and nitrogen metabolism enzyme activities (P < 0.05). Superoxide dismutase activity and malondialdehyde contents were 18.53 unit/g fresh...

The conventional gravimetric methods of estimating soil moisture content (θ) are laborious, time-consuming, and destructive to agricultural fields. We evaluated the performance of DualEM-II sensor in non-destructive way of θ prediction and for predicting θ variations within potato fields in Atlantic Canada. Values of θ were measured from four potato fields in New Brunswick and Prince Edward Island using a pre-calibrated (R2 = 0.98) time domain reflectometry (TDR) from root zone of potato tubers under grid sampling arrangements. Horizontal...

Within a pilot study, after pedological and mineralogical characterization, various kinetic models were tested to fit lead (Pb)-mobilization kinetics from soils at historic mining and smelting sites. Pb mobilization was obtained by modified electro-ultrafiltration (EUF) after addition of diethylenetriaminepentaacetic acid (DTPA) at variable conditions of extraction. 10 fractions were sequentially produced, under mild conditions at 20°C/200 V (to simulate an initial release) for fractions 1-5, and subsequently harder conditions at 80°C/400 V (to simulate a long-term release) for fractions 6-10. The special samples treated within this work yielded higher...

Resistance of common European grasses to diesel oil and petroleum pollution is not well-known. Therefore, this study aimed at determining the level of resistance of selected grasses to pollution by diesel and petroleum using the pot experiment. The achieved results were compared with those determined for grasses grown on the non-polluted soil. Soil pollution with the tested products was found to significantly decrease the yield of all grasses, with the decrease being lower upon soil pollution with petroleum than with diesel oil. The most resistant to the pollution with diesel oil and petroleum were Phleum pratense L., Lolium perenne...

Bacterization of the seeds of spring durum wheat with the strains of gram-positive aerobic spore-forming bacteria Bacillus subtilis IB-21 and B. subtilis IB-22 and gram-negative bacteria Advenella kashmirensis IB-К1and Pseudomonas extremaustralis IB-К13-1А was performed to study its effect on the productivity of plants, their hormonal content and rhizosphere phosphorus (P) status in the field experiments. A. kashmirensis IB-К1 andP. extremaustralis IB-К13-1А were the most capable of mobilizing hardly soluble phosphates in vitro, while P. extremaustralis...

The effect of leaf-applied fertilizers on nutritional status and yields of apple cv. Rubinola grown on two soil types (Luvisol, Cambisol) differing in yield levels was studied in a three-year experiment at the orchard in Vanovice, Czech Republic. Two fertilizers, A (containing N, Mg, Ca, B and Zn) and B (N, B, Zn, Mn and Fe) were applied after blooming, leaves and fruit were analyzed. Zn and B concentrations increased significantly in leaves and fruit in both soils after the application of solution A compared to the control. Foliar fertilizer B increased the concentration of Zn and Mn significantly both in leaves and fruit compared to the control....

This study was conducted to identify ideal irrigation and fertigation levels for maximum yields and profitability of cucumber grown in a substrate-bag cultivation system. The experiment was laid out in randomized complete-block design, with combinations of four drip irrigation rates (75, 100, 125, or 150% of crop evapotranspiration (ETc)) and three fertilization (F) levels (60, 100, or 125% of one dose of Yamazaki nutrient solution formula). The 'irrigation level × fertilization level' interaction significantly affected cucumber yield and nitrogen accumulation. The treatment combination of 125% ETc and 100% F promoted yield relatively best. Plants...
