In the present study, a field establishment was initiated in 2018 with eight treatment conditions using biochar application rates of 0, 10, 20, or 30 t/ha and nitrogen application rates of 0 or 150 kg/ha. After two years, the impact of biochar on carbon-nitrogen distributions, soil aggregate stability, and wheat yields was then assessed. The predominant mechanical aggregates after two years were > 5 mm and 2–5 mm granular aggregates, with notable increases in the amounts of these aggregates following the application of biochar with or without nitrogen that coincided with an increase in soil aggregate mechanical stability. Relative to control...

The effects of the foliar application of plant growth regulators (PGRs), salicylic acid (SA) and ascorbic acid (AA) were studied on yield and some qualitative traits of corn silage under drought stress in a field experiment conducted in the Agricultural and Natural Resources Research Center of Khoy in two consecutive years. The experiment was performed in four replications as a split plot in a randomised complete blocks design. Irrigation treatment was in two levels, ir75 and ir150, and the foliar applications of SA and AA at seven levels (100, 200, and 300 ppm, as well as a control treatment). The amount of water consumed in ir75 and ir150 during...

The Seriphidium transiliense desert pasture is an important spring-autumn pasture in northern Xinjiang, China, and has been subjected to grazing by livestock at different intensities, thus resulting in widespread deterioration of its biodiversity and ecosystem services. To understand the response mechanism of stoichiometric characteristics of desert vegetation to grazing, the leaf carbon (C), nitrogen (N), phosphorus (P) and C : N : P ratios of S. transiliense were studied under different grazing intensities. The results show that the control S. transiliense leaf C, N and P contents and C : N, C : P...

To investigate the impact of different seedling transplanting times on rice growth, the present study evaluated seedling age and root pruning using treatments consisting of root pruning (RC20, RC30, and RC40) and no root pruning (CK20, CK30, and CK40). Quantitative analysis using curve fitting of the changes in dry matter accumulation (DMA) during the seedling and field stages was performed, and the changes in root parameters during the re-greening stage were observed. The results showed that the seedling stage could be divided into a gradual increase period, a rapid increase period, and a slow increase period. Transplanting at different time periods...

In order to provide a theoretical basis for the application of organic selenium (Se) in the production and cultivation of Scrophularia ningpoensis Hemsl. We investigated the effects of selenomethionine (SeMet) on the growth and physiological characteristics of S. ningpoensis seedlings. The results showed that SeMet significantly improved the antioxidant capacity by enhancing the activities of antioxidant enzymes such as superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and ascorbate peroxidase (APX) in the leaves of S. ningpoensis, which significantly reduced the content of malondialdehyde (MDA) and hydrogen peroxide...

Bioproducts and their potential in protection of Brassica napus L. against Verticillium longisporumOriginal Paper

The experiments were carried out on 5 different bioproducts for control of Verticillium longisporum in oilseed rape. For in vitro trials, greenhouse trials and field trials, the bioproducts used were based on bacteria (Bacillus amyloliquefaciens, Pseudomonas veronii) and fungi (Pythium oligandrum, Trichoderma asperellum, Coniothyrium minitans). In in vitro trials, some products (based on Trichoderma asperellum) showed a 100% inhibition effect on the pathogen for a whole trial period of 45 days. The greenhouse trial showed significant differences in bioproducts effectiveness (P <...
