ABSTRACT :
A factorial experiment was conducted in lath house during the season 2011/2012 to study the effect of irrigation with different salinity water taken from three drainages in three levels (4, 5.4, 6.6 ds/m) In addition of tap water (1.2 ds/m.) and the addition of liquid manure (Humi-Feed) with three concentations ( 0, 0.5, 1.0 ml/l) on plant growth and yield of domestic broadbean, using CRD design with three replicates .
Results showed that the salinity level of water irrigation, addition of organic fertilizer and their interaction had a significant effect on growth and yield of plant. The highest average of plant height, number of branches and leaves number /plant, green pods number/plant, pod weight, and yield of pods per plant have been produced from the intraction of tap water with1ml/l of Humi-Feed which reached to 70.67cm, 3.67 branch, 30.11 leaf, 6.11 pod, 19.55 g, and 119.45 g/plant respectively. Water irrigation at (4.0 ds/m.) was superior on the level of (6.6 ds/m.) which gave the lowest average of these characteristics reached to 27.55cm, 1.00 branch, 15.45 leaf, 2.11 pod, 11.25 g/pod, and 23.74 g/plant respectively. Organic fertilizer had obvious effect in reducing the negative effect of soil salinity. |
