Effect of soil water on plant height and root depth and some agronomic traits in common bean (Phaseolus vulgaris) under biological phosphorous fertilizer and irrigation management
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 4
Abstract
After irrigation, water penetration the soil is one of key characteristics changing with time. It may prevent surrounding area of root to achieve adequate water .To study the changes of water penetration in the soil on plant height and root depth and influence of water condition on common bean plant under irrigation management and phosphorylated biologic fertilizer, factorial test was performed in complete randomized block design with 3 repetitions in Astaneh Ashrafiyeh city in the 2011 growing season. In present study, without irrigation conditions and irrigation management with 6, 12 and 18 days interval were selected as first treatment and amounts of phosphorylated fertilized including 0, 1, 2 and 3 g/l per plot was selected as second treatment .Results indicated that plant height and root depth under irrigation was significant in probability level of 1% and biologic fertilizer amount also affected only o plant height. Irrigation management was significant on water rate relative to wet weight in 1% probability level and on water rate relation leaf water was significant in p>0.05.while various amounts of phosphorylated biologic fertilizer didn’t affect on water condition in bean plant. Relative leaf water amount in different treatments ranged between 49.4 and 76.6 % soil penetration rate also decreased during development period compared to early season. Average final penetration rate of soil reached to constant rate of 13 mm.
