Abstract:
A field experiment was conducted during the spring season of 2014 at a private field in Al - qurna county in clay loam soil with a salinity 3.2 ds.m - 1 ; to study the effect of interference between organic and biofertilizer (Azotobacter chroococcum ) on two varieties of sorghum (Sorghum bicolor L.) (Kafair and NK8817).The experiment was carried out by using two levels of organic manure (without application and 10 ton / ha) and three type of bio - fertilizer (no application treatment, first strain of A.chroococcum (A1), and second strain of A. chroococcum (A2) and two varieties of sorghum local variety (Kafair) and the American hybrid (NK8817).The experiment was d esigned by R.C.B.D. in a split - split plot design in three replicates, the main plot was occupied the organic manure, sub. Plots consist bio - fertilizer levels while the sorghum varieties putted in the sub - sub plots. The results showed significant differences between varieties of sorghum, as outweigh the product was Kafair in both the number of days from planting to 50% flowering ( 44.89 day) and 50% flowering to maturity(29.11day), plant height(141.26 cm) , and protein percent (9.34%),while outweigh American hybrid NK8817 in each of the (leaf area3160cm2, the average number of grain in head2021.5 grain head - 1 , 1000 - grains weight 24.07 gm individual plant yield 46.63 gm, total grain yield 3831.8 kg/ha. The results showed that adding bio - fertilizer (A.chroococcum ) increased the qualities above while reducing the number of days from planting to 50% flowering and 50% flowering to maturity with no significant difference between first strain and second strain (A1 and A2) the yield has arrived (4030.7 kg/ ha) for A2 strain respectively compared with no application who gave 2485.8 kg/ ha .The results also showed that adding manure gave a significant increase of the recipes studied plant height (110.40 cm), leaf area (3874cm2), the average number of grain in head( 2005.7 grain head - 1 ), 1000 - grains weight (22.61 gm) individual plant yield( 45.08gm) , total grain yield (3731.4 kg/ha), protein percent ( 9.63% )and protein yield( 355.7 kg/ha) while it reduced the number of days from planting to 50% flowering ( 46.50 day) and 50% flowering to maturity ( 29.83 day) .There was a significant interaction between organic - fertilizer and Cultivated varieties, the NK8817 variety which treatment with 10 ton/ha gives high grain yield reached 4170.4 kg/ha compared with no fertilizer Kafair who gave 2944.5 kg/ha .There was also a significant interaction between bio - fertilizer and Cultivated varieties, the NK8817 variety which treatment with second strain A2 gives high grain yield reached 4431.4 kg/ha compared with no fertilizer Kafair who gave 2192.4 kg/ha .The results showed the interaction between organic - bio - fertilizer was significant interaction in most traits studied the plant which treated with 10 ton organic matter/ha and treatment with second strain A2 gives high grain yield reached 4315.8 kg/ha with no significant difference with first strain A1 .The results also showed the interaction between the three factors gave a significant differences in most traits studied. The highest seed yield ( 4880.9 kg ha - 1 )was obtained by using NK8817 variety which treated with second strain A2 and using 10 ton organic matter/ha while the control gave 2192.4 kg ha - 1 .
