in order to investigate the effect of different cover crops on density and diversity of weeds, the researcher carried out an experiment in randomized complete block design with seven treatments and three replications for two years (2009-2010) in iran citrus research institute. treatments included planting four cover crops of legumes such as clover (trifolium alexandrinum l.), green bean (phaseo...

The utilization of winter-killed cover crops is increasing due to their benefits in intensive cropping systems based on summer cash crops. However, there still a lack knowledge about management temperate climates, where maize planted early under conservation tillage techniques. For these conditions, here we document for the first time various agronomic effects different options. We evaluated pr...

A bioactivity-guided fractionation of the ethyl acetate fraction of the flowers of Onopordum alexandrinum L. (Asteraceae) yielded a new flavonoidal glycoside designated as acacetin-7-O-galacturonide (9), alongside with nine known flavonoids; 6-methoxy-apigenin (hispidulin) (1), acacetin (2), apigenin (3), luteolin (4), kaempferol (5), eriodictyol (6), apigenin-7-O-glucoside (7), luteolin-7-O-gl...

The reproductive potential of Meloidogyne graminicola was compared with that of M. incognita on Trifolium species in greenhouse studies. Twenty-five Trifolium plant introductions, cultivars, or populations representing 23 species were evaluated for nematode reproduction and root galling 45 days after inoculation with 3,000 eggs of M. graminicola or M. incognita. Root galling and egg production ...

The study evaluated replacement of Egyptian berseem clover (BC, Trifolium alexandrinum) with spent rice straw (SRS) of Pleurotus ostreatus basidiomycete in diets of lactating Baladi goats. Nine lactating homo-parity Baladi goats (average BW 23.8±0.4 kg) at 7 d postpartum were used in a triplicate 3×3 Latin square design with 30 d experimental periods. Goats were fed a basal diet containing 0 (C...
