Abstract
An experiment was conducted At Al – Bu – Thiab Village , Ramadi , Anbar on Sandy clay loam soil during summer 2010 to investigate the effect of four levels of K fertilizer (0,40,80 and 120 kg . ha-1 )and four concentrations of B ( 0,100,200and 300 ppm ) on yield of a local cultivar of mung bean . A factorial experiment according to RCBD design was used with three replicates . Results showed that 80 kg K .ha-1 was significantly the best in plant height, podsplant ,pod length and yield( 50.21cm,30.07pod plant,9.44cm,and 1.24 ton.ha-1,respectively )comparison with control which gave the lower value of plant height, pod plant ,pod length and yield. (44.23cm, 19.48 pod plant, 7.99 cm and 0.79 ton. ha-1) Application of B( .0,100,200 and 300 ppm). Caused significant increase in plant height, pods plant , pod length , seeds pod and yield. The highest values were (51.16 cm , 32.10 pod plant , 9.93 cm, 10.10 seed pod and 1.17 ton. ha-1. Respectively when B was sprayed at concentration of 200 ppm , while control hat the lowest values for the mentioned traits (43.42 cm ,20.07 podplant ,7.69 cm ,8.85 seedpod and 0.87 ton .ha-1) ,respectively. Interaction between K fertilizer and B spray significantly affected yield .the highest yield (1.52 ton .ha-1 ) was in 80 K kg. ha-1 with 200 ppm B treatment. Superiority of the third level of both k and B over the highest level was noticed for most traits.
