salinity of water and soil in arid and semi arid regions restricts the growth and yield of crops such as sesame. in order to evaluate yield and yield components of 43 lines and ecotypes of sesame (sesamum indicum l.) under saline condition (ec of irrigation water, 5.2 ds m-1) an experiment was carried out in randomize complete block design with three replications at salinity research station of...
In order to study the effects of seed inoculation with plant growth promoting rhizobacteria (PGPR) and foliar application of nano-zinc oxide (NZO) on yield and rate and period of grain filling of triticale, a factorial experiment was conducted based on randomized complete blocks design with three replications, in Research Greenhouse of Faculty of Agriculture, University of Mohaghegh Ardabili, I...
Seed yield of alfalfa (Medicago sativa L.) is important in determining the effective distribution of new cultivars to farmers. Many genetic and environmental factors affect seed yield. This study was conducted to explain seed yield variation induced by either environmental conditions or cultivars. We analyzed seed yield, aboveground phytomass, harvest index, and seed yield components for a set ...
One of the most complicated issues in plant breeding programs is genotype by environment interaction. To evaluate seed yield stability of 18 chickpea promising lines, a field experiment was conducted using randomized complete block design with four replications in two cropping seasons (2018-19 and 2019-2020) in four research stations (Maragheh, Kurdistan West Azerbaijan and Hamedan), Iran. Comb...
Interspecific and intraspecific hybrids show varying degrees of heterosis for yield and yield components. Yield-component traits have complex genetic relationships with each other. To determine the relationship of yield-component traits and fiber traits with seed cotton yield, six lines (Bt. CIM-599, CIM-573, MNH-786, CIM-554, BH-167, and GIZA-7) and three test lines (MNH-886, V4, and CIM-557) ...
to study the effect of water deficit and plant density on yield and yield components of cumin (cuminum cyminum), an experiment was conducted during the 2002 - 2003 growing season at research farm of zabol university. in this study, the effects of plant density (25, 50, 100, 150, and 200 plants per m²) and water stress (before flowering, flowering, seed filling and seed hardening vs adequate irr...
This study was conducted to evaluate 100 safflower genotypes (Carthamus tinctorius L.) under two moisture stress environments (non-stress and drought stress) during 2012 using a simple lattice design. Results showed that drought stress significantly decreased some traits such as seed yield per plant (21.2%), number of heads per plant (18.7%), oil percent (1.8%) and biological yield (15.3%). Res...
Rice is a worldwide important grain crop, which is considered as the main food and most important source of providing protein and calories for people in the world. Correlation analysis of different traits and yield components with the grain yield is a very important issue in the selection and breeding programs of genotypes. The experiment was performed in the form of completely randomized ...
Identifying key yield components can help establish better crop management strategies to increase crop yield. The present research was conducted in south-western Saskatchewan in 1999 and 2000 to determine the interrelationships among various yield components and their direct and indirect effects of each component on seed yield of field pea (Pisum sativum L.). The semi-leafless cultivar Carrera ...
To evaluate the effect of plant growth promoting bacteria (PGPB) on soil physical and chemical indices, yield and its components of two rice cultivars, an experiment was arranged in Rice Researches Institute of Guilan Province during 2009. The experiment design consisted of four randomized complete blocks in a factorial arrangement having 16 treatments in every block. In this research, two fact...
