An empirical electrical conductivity assessment of nanofluids comprising CuO nanoparticles water-based in different concentrations, particles size and various temperatures of nanofluids has been carried out in this paper. These experimentations have been done in deionized water with nanoparticles sizes such as 89, 95, 100 and 112 nm and concentrations of 0.12 g/l, 0.14 g/l, 0.16 g/l and 0.18 g/...

Abstract The research was carried out in lath house of the Department Horticulture and Landscaping - College Agriculture / University Anbar during two growing season 2021-2022, order to study effect spraying with normal nano iron on growth flowering petunias. Normal used concentrations (0, 50 100 mg L -1 ), which represented by (F0, F1 F2) respectively, while sprayed 10 20 ) it (NF0, NF1 NF2) r...

In the course of studies on biologically active substances from pathogenic microorganisms, a new antibiotic SO-75R1 was isolated from the mycelium of Nocardia brasiliensis IFM 075. This paper describes the fermentation, isolation and structural elucidation of SO-75R1. The seed broth was prepared by inoculating mycelial elements of the producing strain (IFM 075) grown on Sabouraud dextrose agar ...

The adaptive responses of crop genotypes and patterns of genotype x location (G x L) interaction are important to crop improvement as they are the basis for selection for specific adaptation and for elucidation of the causes of G x L interaction. Their legitimate assessment, however, requires yield data for the test genotypes for a large number of sites and over multiple years. Such data are se...

the effect of ca, zn and b foliar application (five g l-1) and their mixed applications as well as two harvest dates (1st and 15st of august) on ppo activity of two commercial asian pears (‘ks’9 and ‘ks’13) fruits at the time of harvest and during storage were investigated. results showed that the ppo activity increased from harvest time to three months after storage and then decreased. during ...

Abstract Allelopathy is a phenomenon by which plants positively or negatively affect neighboring releasing allelopathic compounds. These allelochemicals are secondary metabolites found in different concentrations shoots, roots, leaves, flowers, and even pollen grains. Allelochemicals have potential as natural bioherbicides for controlling weeds when applied the form of extracts through intercro...
