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

Abstract

A field experiment was conducted during the autumn season 2021 in one of the farms affiliated to the district of Kuthi (Jableh) located in the north of Babylon province, at longitude 44 east and latitude 44 north, in a sandy loam texture soil. The arrangement of the split plot was used according to the randomized complete block design (R.C.B.D) with three replicates, biofertilizer levels 0, 2, 4, 6 kg ha-1 were used, which occupied the main plots, while the genotypes occupied sub plots, namely (Aniqath, Buhouth70, Rabih, Alkayr, Syrie and American). The traits of plant height, leaf area, chlorophyll content of leaves, number of grains in panicle, weight of 1000 grains, grain yield and biological yield were studied. The results showed the treatment of adding 4 kg ha-1 of biofertilizer excelled in the average plant height cm2 214.14, leaf area and leaf cm2 7897 content of chlorophyll 55.72. Whereas the addition of 6 kg ha-1 excelled and gave the averageshowed superior in triats number of grains in panicle2816, the weight of 1000 grains 27.487, and the grain yield was 7.02 tons.ha-1 and the biological yield was 21,791 tons ha-1. The results also showed a significant difference between the genotypes, where the genotypes Buhouth 70 surpassed in the average plant height cm2 285.94 and weight of 1000 grains 36.212 g, and the biological yield was 31,038 tons ha-1, while the Rabih cultivar excelled in the average leaf area 8560 cm2, number of grains per panicle 3885, grain yield 7.353 tons ha-1, harvest index 36.891%. The nteraction between levels of bio-fertilizer and gentypes showed the highest of grain yield trait at the highest level of bio-fertilizer, which amounted to 8.030 tons ha-1 for Rabih genotype.
