Seed priming, as a low-cost method, is a technique commonly used to increase germination percentage especially under unfavorable conditions. The objective of this study was to evaluate the effects of bio-priming on the germination of canola (Brassica napus L.) seeds under saline (NaCl) conditions. Seeds of canola var. Hyola 401 were inoculated with plant growth-promoting microorganism (PGPM) in...

BACKGROUND Seed size has significant implications in ecology, because of its effects on plant fitness. The hybrid seeds that result from crosses between crops and their wild relatives are often small, and the consequences of this have been poorly investigated. Here we report on plant performance of hybrid and its parental transgenic oilseed rape (Brassica napus) and wild B. juncea, all grown fr...

The aim of the study was to determine the technical and economic optimum levels of raw and treated common vetch seed (CVS) on the productive performance and egg quality traits in laying hens. One hundred and sixty-eight White (Lohmann) layers, 30 weeks of age were randomly assigned to seven groups, each with six replicate cages of four hens. Control diet (C) and basal diets supplemented with 12...

Seed limitation, defined as the failure of seeds to arrive at sites favorable for recruitment, may be a critical force structuring plant communities. When seed limitation is strong, interspecific competition is reduced, and competitive exclusion may be slowed to the extent that diversity can be maintained through speciation and migration. In mature tropical forests, seed limitation may be espec...

The study was undertaken to examine the profitability of contractual bread wheat seed production in Kudmi village of Mecha district in Amhara region, Ethiopia. Primary data were collected from fourteen seed growers using structured questionnaire. The analytical tools employed include descriptive statistics and average net farm income. Results revealed that the average total cost of production p...

Smallholders in Asia and Africa require low-cost seed drills for minimal soil disturbance while establishing various crops. A seed drill that can be drawn by the widely-available two-wheel tractor (2WT) is an attractive option for mechanization of no-till in small-sized fields. The Versatile Strip Seed Drill (VSSD) was designed with the capacity to make up to 40 mm wide and 60 mm deep strips in...

A large body of research has documented the effect of seed priming ongermination, emergence and crop yield. In such research, seed priming has beenfound to have a positive, negative or no effect. Meta-analysis can help tosummarize and interpret a collection of experiments. The aim of this study was toconduct a meta-analysis to synthesize published data from studies addressing theeffect of seed ...

the main objective of this study was to determine the economical level of inputs applied in production of sugar beet by eglid region farmers. therefore data set was obtained from 55 farmers through interview and completing questionnaire. the farmers were selected based on a two-stage random sampling method.  marginal productivity of inputs was studied using cobb –douglasand transendental produc...
