In order to evaluate the effects of seed priming with Plant Growth Promoting Rhizobacteria (PGPR) on dry matter remobilization and yield of maize (Zea mays L.) hybrids, a factorial experiment based on randomized complete block design with three replications was conducted in 2009 at the Research Farm of the Faculty of Agriculture University of Mohaghegh Ardabili. Factors included seed priming of...
The need to identifying seeds with low vigor and poor emergence led to introduce of various seed vigor tests. The purpose of this experiment was to assess the ability of controlled deterioration test for evaluation of seed vigor and prediction of oilseed rape seed lots emergence in the field. Samples of 19 seed lots were obtained from nineteen farmers of Razavi and Northern Khorasan Provinces...
Objective: To evaluate the soil cover with corn-neem biomass for Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) management in INIAP H601 corn hybrid, at Pechiche, Los Ríos, Ecuador. Design/Methodology/Approach: Two treatments were evaluated: 1) a treatment using 2.0 t ha-1 before sowing, plus two foliar applications, 10 and 20 days after sowing; 2) control without cover, completely...
Growth and grain yield of irrigated barley cultivars (Valfajr, Binam and Raihaneh) was investigated at 4 sowing dates (6, 22 Oct. and 14, 20 Nov.) in Karaj region. The effect of sowing date, genotype and their interaction on grain yield were statistically significant. Early and late sowing enhanced cold damage. However, the damage was more in late sowings. It was estimated that the optimum sowi...
This study was carried out to determine effects of different durations (20, 40, 60 days and control) of cold stratification treatments on seed germination and to overcome dormancy in seeds of twelve different drought tolerant plants. The species used in this study were Arbutus andrachne L., Cistus creticus L., Colutea armena Bois. Huet., Cotinus coggygria Scop., Cotoneaster numullaria Fisch. an...
Genetically modified, insect-resistant Bacillus thuringiensis (Bt) cotton is cultivated extensively in Pakistan. Past studies, however, have raised concerns about the prevalence of Bt cotton varieties possessing weak or nonperforming insect-resistance traits conferred by the cry gene. We examine this issue using data drawn from a representative sample of cotton-growing households that were surv...
Germinant sowing is operational for tree nurseries in South Africa. The technique reduces seed costs for eucalypts and pines. Filled cell percentage is usually near 98%. Seed efficiency at many North American container nurseries can be improved by adopting either germinant sowing or single sowing technology. Tree Planters' Notes xx(x):xx; 199x. INTRODUCTION Managers at most container nurseries ...
In the case of delayed planting of cotton, using cotton plantlets may lead to a better acquisition of light and water throughout the plant growth and hence an enhanced plant growth and yield. Therefore, in order to evaluate the effect of transplanting method on cotton quantitative and qualitative traits, a 2-year field research was carried out using a split plot design experiment with different...
