The Effect of Bio-Fertilization in Growth and Yield four Two Types of Sorghum Sorghum bicolor (L.)Moench

Effect of Different Levels of Bio Fertilizer on Growth and Yield of Sorghum Genotypes

“…Table (5) showed that there were significant differences in the number of grains in the panicle by biofertilizer levels adding, Where the B3 level achieved the highest average of 2316 grains, while the lowest number of grains at the non additon (Bo) which amounted to 2109 grains per panicle. This may be due to the role of biofertilizer in increasing the accumulation of dry matter, which caused an increase In the starch of grains, which was reflected in the increase in the number of grains of the plant.This is consistent with what was found by [15,16] and [11] who praised the increase in the number of grains as a reflection of the effect of bio-fertilizer and the accumulation of nutrients and the processing of emerging grains by dry matter which plays a role in increasing the seed fertilization rate.cultivars differed in the average number of grains in panicle, as the cultivar rabih gave the highest average number of grains, which amounted to 3885 grains, while the lowest number achieved in the Syrian cultivar was 1527 grains.This may be due to the different cultivar in the locations of the genes that dominate this trait . It is verified with the results of [17,18], who found that the difference in the number of grains in cultivar is due to the genetic variation between cultivars.It is noted from Table (5) that there was a response of the cultivars in the average number of grains by increasing the levels of bio-fertilization, as the highest increase in this trait was achieved in the cultivar rabih at the B3 level, which amounted to 4683 grains/ panicle.…”

“…The results in Table (7) showed that there were significant differences in the effect of biofertilizer levels in grain yield in sorghum. The B3 level achieved the highest average grain yield of 7.026 tons ha -1 , while the lowest yield was achieved at the Bo level of 5.925 tons ha -1 This is due to the role of bio-fertilizer in increasing the plant's supply of nutrients, and the excel of this level is due to the excelled of the two cultivars of number of grain in panicle (table 5 ) and weight of 1000 grains (table 6), that were reflected in the grain yield and this agrees with what was obtained by [11] and [21]., who explained that the bio-fertilizer caused an increase in the grain yield over an increase in its components.It is also noticed from the same table that there is a significant difference between the cultivated cultivars, where the cultivar excelled by giving the highest average grain yield amounting to 7.353 tons ha -1 , while the American cultivar gave the lowest average yield of 5.456 tons ha -1 This is due to the rabih cultivar in the number of grains, which caused an increase in the grain yield, and this is proven by what was found by [22,23], who showed that the cultivars differ among themselves in yield and its components.It is clear from Table (7) that there was a response to sorghum cultivars in grain yield by increasing the levels of bio-fertilizer.Whereas, the lowest yield of the American cultivar when the control treatment B0 was 5.083 tons ha -1 Table 7. Effect of adding the bio-fertilizer in grain yield ton ha -1 of different sorghum genotypes and their interactions.…”

“…Chlorophyll content of the leaves (Spad) The flag leaf was measured at the completion of flowering at a rate of five readings for each experimental unit using the SPAD 502 device. Number of grains in IOP Publishing doi:10.1088/1755-1315/1158/6/062019 3 panicle:-The number of grains per cob was calculated from the relative relationship between grain weight and the weight of 1000 grains in each experimental unit [11]. 1000 grains weight (g) 1000 grains were taken from the samples according to the grain yield then weighted at a humidity of 13%.…”

Effect of Seed Stimulation by Alpha-Amylase Enzyme, Stimulus Temperature Degree and Sowing Dates on some Growth Characteristics of Sorghum

“…Delayed planting accelerates flowering, but this does not prevent pollination and fertilization processes at high temperatures, reducing grain filling rate and yield. Late planting encourages early flowering and maturity due to shorter daylight compared to early planting, which has not reached the critical threshold that encourages flowering [9]. [10] found a significant effect of planting dates on plant height and leaf area, in July 15 th showing the highest rates of plant height and leaf area reached to 175.66 cm and 5136.24 cm 2 , respectively, compared to the other two dates.…”
