to study the effect of planting date on morphological characteristic, yield and essential oil content of achillea millefolium sub sp millefolium.l., an experiment in a randomized complete blocks design (rcbd) with four treatments including four planting date (6 july, 1 august, 7 september and 7 october) in four replications was conducted. during the growing stage and at the end of experiment pe...

A field experiment was conducted to observe the influence of a cover crop (winter wheat, Triticum aestivum L.), and a perennial weed (dandelion, Taraxacum officinale Weber ex Wigg.), on vesicular-arbuscular mycorrhiza (VAM) inoculum potential, soil aggregation, and maize yield after one season. Mycorrhizal colonization of maize roots was higher following the autumn planting of either winter whe...

The present study an attempt has been made to investigate the effect of Seaweed Liquid Fertilizer of Rosenvigea intricata with or without chemical fertilizer on seed germination, growth, yield, pigment content and soil profile of Abelmoschus esculentus was analyzed. The seed germination, shoot length, root length, number of lateral roots, number of leaves, number of vegetables, length of vegeta...

African yam bean (Sphenostylis stenocarpa) is an underexploited legume with the potential of becoming an alternative food staple to alleviate the problem of food security. An assessment was carried out on the growth and yield of AYB affected by Telfairia mosaic virus (TeMV) Infection. Telfairia mosaic virus caused severe mosaic, leaf distortion and malformation on AYB. Analyses of results revea...

This study investigated the effects of the sawdust vermicompost extract (aqueous extract) on yield and chemical quality of Dracaena marginata var.‘Tricolor’ grown under four sawdust vermicompost extract solutions (0, 250, 500 and 1000 ppm). The sawdust vermicompost extract was prepared using non-aerated extraction methods with 1:10 (v/v) of sawdust vermicompost to water and was sprayed three ti...

Root traits influence the amount of water and nutrient absorption, and are important for maintaining crop yield under drought conditions. The objectives of this research were to characterize variability of root traits among spring wheat genotypes and determine whether root traits are related to shoot traits (plant height, tiller number per plant, shoot dry weight, and coleoptile length), region...

rice (oryza sativa l.) is one of the iran's most strategic crops with water shortage as the most important abiotic stress limiting its yield. in the present research the effects of: variety, water regime, nitrogen (n) and phosphorus (p) levels on n, p and k uptake were studied under greenhouse conditions. the experiment design was a factorial one based upon a randomized complete blocks of ...
