in order to study the effect of sowing date and plant density on ear of sweet corn an experiment was conducted in gorgan reaserch station since june 2001 during 3 years. in this experiment five sowing date (24th june, 9th july, 24th july, 18th agust and 23th agust) and four plant density (45000, 55000, 65000 and 75000 plant per hectar) were evaluated in form of factorial experiment (5×4) within...

Efficient use of space and high yields are critical for long-term food production aboard the International Space Station. The selection of a full dwarf wheat (less than 30 cm tall) with high photosynthetic and yield potential is a necessary prerequisite for growing wheat in the controlled, volume-limited environments available aboard long-term spaceflight missions. This study evaluated the phot...
