Abstract
A field experiment was conducted on a clay loam soil low in organic matter and N in a Zindani soil series of a Typic Torrifluent soil class to investigate the effect of soil application of PGPR (plant growth-promoting Rhizobacteria) at the rate of 0 (control) and 50 kg ha-1 on the yield and TSS content of two distinct table beet genotypes (Detroit and Dark Red) under the agro-climatic conditions of Dera Ismail Khan (D.I.Khan), Pakistan. The experiment was carried out at the using factorial arrangement in a Randomized Complete Design with three replications. The data were collected on the beetroot diameter and length, beetroot yield and TSS content. The genotype Detroit outyielded Dark Red variety significantly, while the genotype Dark Red had significantly higher TSS content. The results showed that soil application of PGPR at the rate of 50 kg ha-1 increased the beetroot diameter, beetroot yield and TSS content of table beet significantly (P<0.01). The increase in beetroot diameter, beetroot yield and TSS due to soil application of PGPR, over control was 11.8, 19.9 and 10.0% over control, respectively. The interactive effects of genotype and PGPR application were highly significant and indicated a better performance of both genotypes (Detroit and Dark Red) with PGPR (50 kg ha-1) application. According to the findings, the table beet genotype Detroit cultivated with PGPR applied to the soil (50 kg ha-1) may be suggested for the soil and climate of D.I. Khan, Pakistan.
