investigation the archetype of mother can help the reader to understand poes works, especially his fiction, better, if not fully. motivated by internal and external drives to get into the universe in its manifold form poe was impelled to art and, from various modes of art, to symbolism. how much was poe successful to produce works of art has been a matter of dispute among critics. however, ther...
The mungbean production area is increasing in Australia due to increasing demand for the grain in Asian countries. However, the mungbean crop is generally grown with wide row spacing, and therefore, it is prone to heavy weed infestation which has a significant impact on the mungbean grain yield. Experiments were conducted in 2015 and 2016 to determine the row-spacing impact on crop yield and we...
given the importance of sustainable agricultural development, using non-chemical weed management such as cover crops and decreasing row spacing has an importance in weed control and reducing herbicide use. in order to an experiment was conducted at agricultural research site in agricultural college, university of mohaghegh ardabili in 2011. the experiment done as factorial based on randomized c...
Knowledge of the effects of row spacings and seeding rates on dual-purpose forage and seed production of an annual legume crop is essential for its proper agronomical exploitation. In this study, the effects of various row spacings and seeding rates on dry matter and seed yield in berseem clover (Trifolium alexandrinum L.) were evaluated in two consecutive years. The experimental design was a s...

(line: cos16). the investigation was conducted as cut terraces and in terms of complete random blocks in three replicates at brujerd agricultural research and natural resources in the agricultural year 2009-2010. here, the main terraces with th...
It is uncertain how corn (Zea mays L.) yield would be affected by planting in a twin-row orientation in the southeastern US. The objectives were to compare corn grain yield when: (i) planted in single and twin rows, (ii) plant densities at recommended (1R) and twice the recommended (2R) rate, and (iii) N rates of 168 and 336 kg/ha. Corn was irrigated using a subsurface drip irrigation system. T...
A field experiment was conducted at wondo genet Agriculture research center under irrigated condition to determine the effect of intra and inter-row spacing on growth and yield of Artemisia (Artemisia annua L.) during the two successive seasons of 2013 and 2014. Factorial combinations of four intra-rows (40, 60, 80, 100 cm) and four inter-row plant spacing’s (60, 80, 100, 120 cm) were laid out ...
