“…Mandal et al (2007) reported a close relationship between the soil microbial biomass and crop yields under both greenhouse as well as field conditions. Jannouraa et al (2013) demonstrated close relationships between grain N and P concentrations and microbial biomass C, N, and P, thus suggesting the use of soil microbial biomass as an indicator of nutrient availability to plants. Microorganisms in soil played an important role in nutrient cycling and plant nutrition, reduced pathogen populations, increased soil organic matter, total carbon, cation exchange capacity, and lowered bulk density thus improving soil quality (Bulluck et al 2002).…”

Five strains of Streptomyces sp. ; demonstrated previously to have potential for control of Fusarium wilt disease in chickpea and plant growth promotion [PGP] in rice) were evaluated for their PGP capabilities in chickpea in the 2012-2013 and 2013-2014 post-rainy seasons. The plots inoculated with Streptomyces sp. significantly enhanced number of nodule, nodule weight, root weight, and shoot weight at 30 days after sowing (DAS) and number of pod, pod weight, leaf area, leaf weight, and stem weight at 60 DAS in both seasons over the un-inoculated control plots. At chickpea crop maturity, all of the Streptomyces strains significantly enhanced stover yield, grain yield, and total dry matter in both seasons over the un-inoculated control. In the rhizosphere, the Streptomyces strains also significantly enhanced soil biological and mineral nutrient activities including microbial biomass carbon, dehydrogenase activity, total nitrogen, available phosphorous, and organic carbon in both seasons over the uninoculated control. All of the five strains were found superior in terms of nodule formation, root and shoot development, and crop productivity; however, KAI-xx had little edge over the other five strains. Scanning electron microscopy (SEM) analysis had revealed the success of colonization by the strains of Streptomyces sp. of the chickpea roots. Quantitative real-time PCR (qRT-PCR) analysis of selected PGP genes revealed overall upregulation of β-1,3-glucanase, indole-3-acetic acid, and siderophore genes in the Streptomyces species studied. This investigation further confirms the broad spectrum of PGP activities by the selected Streptomyces sp.

“…Global yields of both chickpea (968 kg ha −1 ) and pigeonpea (762 kg ha −1 ) have been relatively stagnant (FAOSTAT 2013) for the last five decades in spite of using various conventional and molecular breeding approaches and extensive use of inorganic fertilizers and pesticides that created environmental and health concerns. With the ever increasing cost of pesticides and fertilizers and concern over environmental degradation, there has been a resurgence of interest to develop environment-friendly methods of crop production and protection (Jannouraa et al 2013). The environment-friendly options include the use of plant growth-promoting (PGP) microbes, antagonistic or entomopathogenic microbes, animal wastes, botanicals and crop residues serves as an alternative to chemical fertilizers and pesticides (Rupela et al 2005).…”

Seven strains of bacteria [Pseudomonas plecoglossicida SRI-156, Brevibacterium antiquum SRI-158, Bacillus altitudinis SRI-178, Enterobacter ludwigii SRI-211, E. ludwigii SRI-229, Acinetobacter tandoii SRI-305 and Pseudomonas monteilii SRI-360; demonstrated previously for control of charcoal rot disease in sorghum and plant growth-promotion (PGP) in rice] were evaluated for their PGP and biofortification traits in chickpea and pigeonpea under field conditions. When treated on seed, the seven selected bacteria significantly enhanced the shoot height and root length of both chickpea and pigeonpea over the un-inoculated control. Under field conditions, in both chickpea and pigeonpea, the plots inoculated with test bacteria enhanced the nodule number, nodule weight, root and shoot weights, pod number, pod weight, leaf weight, leaf area and grain yield over the un-inoculated control plots. Among the seven bacteria, SRI-229 was found to significantly and consistently enhance all the studied PGP and yield traits including nodule number (24 and 36%), nodule weight (11 and 44%), shoot weight (22 and 20%), root weight (23 and 16%) and grain yield (19 and 26%) for both chickpea and pigeonpea, respectively. When the harvested grains were evaluated for their mineral contents, iron (up to 18 and 12%), zinc (up to 23 and 5%), copper (up to 19 and 8%), manganese (up to 2 and 39%) and calcium (up to 22 and 11%) contents in chickpea and pigeonpea, respectively, were found enhanced in test bacteria inoculated plots over the un-inoculated control plots. This study further confirms that the selected bacterial isolates not only have the potential for PGP in cereals and legumes but also have the potential for biofortification of mineral nutrients.

“…Sharma et al (2013) found that addition of manure in the NPK treatments combination improved soil fertility. These treatments also increased cation exchange capacity (CEC), soil enzyme activity (Piotrowska and Wilczewski 2012), and soil microbial biomass , enhanced nutrients uptake, and increased photosynthetic rate (Jannoura et al 2013;Jannoura et al 2014), enhanced diversity of microorganism and supported plant growth (Zhang et al 2012;Hamm et al 2016).…”

Abstract. Kuntyastuti H, Sutrisno. 2017. Effect of manure, Phosphate Solubilizing Bacteria, and chemical fertilizer application on the growth and yield of soybean. Nusantara . This study aimed to determine the dosages of organic, chemical and biological fertilizers for optimum growth and yield of soybean grown in acidic dryland. Treatments applied were twelve combinations of inorganic fertilizer, phosphate solubilizing bacteria (PSB), and manure. These treatments were arranged in a randomized block design, each was three replicates. The growth variables of plant height and chlorophyll index were observed in every two weeks interval, started at two weeks after planting. Root length and number of nodules were observed at 45 days after planting when the maximum vegetative growth occurred. Stem and root dry weight, number of filled and empty pods, pod dry weight, grain weight, and number of seeds per plant were observed at harvest. Optimum soybean growth and yield were achieved when soybean plants were treated with a combination of 1500 kg ha -1 of manure + PSB +150 kg ha -1 of NPK chemical fertilizer.Keywords: Chemical fertilizer, dry acid soil, manure, phosphate solubilizing bacteria, soybeanAbbreviations: NPK = nitrogen, phosphate, potassium, PSB = Phosphate solubilizing bacteria, DAP = day after planting, WAP = week after planting, LCI = leaf chlorophyll index, CEC = cation exchange capacity
