Crop depends on its canopy to intercept solar radiation to drive both assimilation and water, nutrient absorption for its growth. Field experiments, involving three sowing time and three sowing rate, were conducted at Luancheng Station to investigate the effects of canopy size and development on crop growth and radiation use efficiency (RUE) of winter wheat during 2009/2010 and 2010/2011 gr...

An experiment was conducted to evaluate the effect of different sowing time on seed yield and quality in under used medicinal plant babchi. The study was carried out for 12 months from January to December. Results showed that the seeds sown in November month recorded the maximum seed yield and quality parameters followed by October month than other months. November month recorded the maximum fi...

Molecular markers have been used to predict the genetic variance of segregating soybean populations by measuring the genetic distance between parents. For this purpose we analyzed the genetic distance among six pairwise combinations of four soybean lines grown in Southern Brazil. The AFLP-based distances (AFD) were estimated with 21 primer-pair combinations. Additive genetic variance (D) was es...

the increasing needs for energy, its high price and its environmental impact on greenhouse gases emission and limited energy resources due to increased research on energy balance in crop production systems. the objective of this research was to compare seedbed preparation and sowing methods in wheat production in kordkoy region with respect to energy use and efficiency. fifteen wheat fields wer...

In order to investigate the effect of planting date and sowing method on ear yield, water use efficiency and some physiological characteristics of sweet corn, an experiment was carried out as a split plot based on a randomized complete block design with three replications in Yasouj, south-west of Iran. Planting date consisted of five levels (4 May, 19 May, 4 June, 19 June, 5 July) and considere...

Mortality and sub-lethal effects on honey bees have been related to the sowing of maize seeds dressed with neonicotinoid insecticides. Pneumatic precision drills, used for commercial seed sowing, play a role in the dispersion of the abrasion dust because abrasion dust is emitted with the airstream generated by the drill’s fan. The paper provides the results of the assessment of dust drift both ...

Our sowing date experiment took place in the Demonstration Garden of Institution of Plant Sciences, Centre for Agricultural Sciences of University of Debrecen, in 2012-2014. The paper contains data of test year 2014. Our purpose, besides several other examinations, was to observe how sowing date influences the leaf area index and the activity of photosynthesis of maize hybrids, and how those fa...

The present work was conducted to find out the effect of biofertilizer formulated with four species of bacteria (two species of Azotobacter and two species of Lysobacter) and zinc sulphate. Field experiments with mustard plant were conducted to study the effectiveness of soil application of zinc sulphate and biofertilizer at 0, 10, 20, 30, 40, 50 days after sowing. Plant height and condition of...

ABSTRACT- Annual Medicago species (Medicago spp.) are native to the Mediterranean region and widely used in fields and pastures in Iran. There are several methods of sowing annual Medicago species, each with different effects on the performance. However, there is currently no sufficient information about the appropriate methods for sowing Medicago species. In order to evaluate methods of sowing...

The influence of pre-sowing treatments using hydropriming, osmopriming and halopriming in laboratory and/or nursery tests on seedling emergence, seedling weight and plant growth of endive and chicory was examined. Halopriming (KNO3) or growth regulators (gibberelic acid; GA3) improved the rate of germination of endive and chicory and reduced the mean germination time needed. 30 min pre-sowing t...
