journal of kerbala university, 2014, Volume 10, Issue 4, Pages 16-20

An experiment was conducted in a field of Crops Department in Abu Gharaq / Hilla / Babylon province during the growing season 2013 to determine the impact of four sowing dates (5/15, 15/6, 15.7 and 8/15) and four spraying treatments (salicylic acid 0.5 and 1 mM, humic acid, high phosphorus fertilizer as well as control treatment ) on some physiological characteristics of mung bean plant. Randomized complete block design under split plot arrangement in triplicate was used . The plants were sprayed twice after 30 and 45 days from sowing time. The results were showed superiority of second date in leaf content of nitrogen, phosphorus, calcium, and the superiority of the fourth sowing date in leaf potassium content . Spraying high phosphorus fertilizer was superior in increasing leaf phosphorus content. Spraying humus and High phosphorus fertilizer were superior compared to other treatments in the leaf content of chlorophyll, calcium, potassium and nitrogen. The interaction had a significant effect on the previous mentioned characteristics
