“…Population of diazotrophic bacteria was more in N 75 treatment as compared to N 0 and N 150 indicating that starter dose of N is required for the initial growth and root biomass development for proper colonization of inoculated bacteria. Fuentez-Ramirez et al (1999) and Muthukumarasamy et al (1999b) have demonstrated the detectable counts of naturally occurring Gluconacetobacter diazotrophicus in only those areas where N-fertilization was low and hypothesized N to be the probable key factor for its association. Total population of diazotrophs in sugarcane is negatively influenced by increasing nitrogen level (Reis Junior et al 2000).…”

Seven Gluconacetobacter diazotrophicus strains from sugarcane roots were screened for their efficiency to promote growth and nutrient uptake in sugarcane at three levels of urea N (0, 75, and 150 kg N ha À1 ). Inoculation by these strains improved germination, tiller number and plant height. N-uptake and apparent N-recovery increased due to inoculation and the effect was more at N 75 level. Gluconacetobacter diazotrophicus isolate IS100 was found to be the most efficient in promoting plant growth and nutrient uptake in sugarcane.

“…Similarly, Hongrittipun et al (2104) isolated high numbers of nitrogen-fixing bacteria from roots and leaves of rice. Most researches on sugarcane endophytic bacteria have focused on diazotrophicus bacteria among which there are important representatives such as Acetobacter diazotrophycus and species like Herbaspirillum (Muthukumarasamy et al, 1999). In India, research on sugarcane endophytic bacteria showed that diazotrophicus bacteria had less population than the other bacteria (Suman et al, 2001).…”

Pirhadi et al.: Impact of soil salinity on diversity and community of sugarcane endophytic plant growth promoting bacteria (Saccharum officinarum L. Abstract. The aim of this study was to isolate and identify culturable bacterial endophytes from sugarcane grown in saline and non-saline soil and assay some plant growth-related traits and evaluate selective isolate potential to improve growth, yield and grain phosphorus uptake of wheat. Endophytic bacteria associated with sugarcane grown in saline and non-saline soil were isolated from roots, stems and leave and tested for their ability to fix nitrogen, indole acetic acid (IAA) production and dissolution of insoluble phosphorus. A total of 55 endophytic bacteria were isolated from leaves, stems, and roots of sugarcane from saline and nonsaline soil. The results revealed a prevalence of Bacillaceae, with Bacillus sp. being the most frequently isolated bacterium. Salinity had the effect on bacterial community structure with the higher diversity of root entophytic bacteria in saline soils. From the isolates, four strains were shown to produce IAA and 19 strains showed the ability to solubilize phosphate, but twelve isolates having the best characteristics tests were identified using 16S rRNA gene sequencing. From the isolates Pseudomonas sp. SugS_49 with more phosphorus dissolution ability selected for evaluation on wheat growth. Application of Pseudomonas sp. SugS_49 caused increased growth, grain yield and phosphorus uptake of wheat.

“…In none of these programmes were large amounts of N fertilizer utilized and because of this, their best materials have little demand for N fertilizers and an effective association has developed between endophytic Nfixing bacteria and the plant. Apart from N fixation, other properties associated with G. diazotrophicus are P-solubilization, the production of the plant growth hormone indole acetic acid (IAA) and the suppression of red rot disease (Muthukumarasamy et al 1999;Suman et al 2001). Suman et al (2000) reported that the native occurrence of G. diazotrophicus in sugarcane varieties of sub-tropical India is very low and that through the inoculation of efficient indigenous isolates, their number, plant N uptake and nutrient use efficiency could be increased at different N levels (Suman et al 2005).…”

A 3-year field trial of sugarcane, comprising 11 treatment combinations of different organic manures with and without Gluconacetobacter diazotrophicus (Gd), NPK and an absolute control, on an inceptisol was conducted to assess the effect of these treatments on sugarcane total and economic yield, the benefit:cost ratio, nutrient balance and soil quality in a sugarcane plant-ratoon system. The highest cane yield (78.6 t ha À1 ) was recorded in the plant crop given vermicompost + Gd, whereas ratoon yields (first and second) were highest (80.8 and 74.9 t/ha À1 , respectively) with sulphitation press mud cake (SPMC) + Gd. In both plant and ratoon crops, a number of different organic manures produced the highest cane yield that was also statistically similar to those obtained with using the recommended NPK levels (76.1, 78.2 and 71.7 t/ha for plant crop and subsequent two ratoons, respectively). The highest benefit:cost (B:C) ratio in the plant and two ratoon crops (1.28, 2.36, 2.03 respectively) were obtained with the addition of SPMC + Gd. The nutrient balance for NPK in the soil was highest in the SPMC + Gd treatment. The highest increase in organic C (94%) and total N (87%), in comparison to the initial level, and soil microbial biomass C (113%) and soil microbial biomass N (229%), in comparison to the control treatment, was recorded with the addition of SPMC + Gd. The maximum decrease in soil bulk density (BD) (12%) with an increase in soil aggregate (17%) and water infiltration rate (35%) was obtained with the addition of SPMC. Overall, the sugarcane crop responded well to different organic manures in a multiple ratooning system with a better economic output and improved soil quality. Strategic planning in terms of an integrated application of these manures with inorganic chemicals will not only sustain our soils but will also be beneficial for our farmers in terms of reducing their dependence and expenditure on chemical fertilizers.
