Pgpr Activity

One hundred strains of Rhizobium leguminosarum bv. trifolii were isolated from roots of wheat cultivated in rotation with clover in two different regions of Morocco. The isolates were first screened for their effect on the growth of the cultivar Rihane of wheat cultivated in an agricultural soil under greenhouse conditions. After 5 weeks of growth, 14 strains stimulating the fresh or dry matter yield of shoots were selected and used in a second pot inoculation trial performed with two different agricultural soils. The results show that the strains behaved differently according to the soil used. In the loamy sand Rabat, strain IAT 168 behaved potentially like a plant growth promoting rhizobacteria (PGPR), as indicated by the 24% increases (P < 0.1) observed in wheat shoot dry matter and grain yields. In the silty clay Merchouch, no PGPR activity was observed, and 6 strains showed a significant deleterious effect on yields. These observations suggest that it is very important in a crop rotation system to choose a R. leguminosarum bv. trifolii strain that is effective with clover and shows PGPR activity with wheat to avoid deleterious effects on wheat yields.Key words: deleterious bacteria, PGPR (plant growth promoting rhizobacteria), Trifolium alexandrinum, Triticum aestivum.

The field experiment was conducted during 2015-16 to study the effect of biofetilizer inoculation [control, Mesorhizobium only, Mesorhizobium + RB-1 (Pseudomonas argentinensis) and Mesorhizobium + RB-2 (Bacillus aryabhattai)] and four levels of phosphorus (0, 15, 20 and 25 kg P2O5 ha-1) on chickpea growth. RB-1 and RB-2 were the plant growth promoting rhizobacteria (PGPR). Biofertilizers could play a crucial role in reducing the dependence on chemical fertilizers by fixing the atmospheric nitrogen for crop and/or by increasing the availability of phosphorus and phytohormones to the crop. The 16 treatment combinations were laid out in Factorial Randomized Complete Block Design and replicated three times. In biofertilizer treatments, Mesorhizobium + RB-1 proved superior over control and sole inoculation of Mesorhizobium and at par with Mesorhizobium + RB-2 with respect to plant height (cm), number of branches (plant-1), shoot and root dry matter (kg ha-1) which were recorded at 30, 60 90, 120 days after sowing (DAS) and at harvest. Application of 25 kg P2O5 ha-1 gave the highest values of all the growth at-tributes viz. plant height (60 cm), number of primary (5.3) and secondary (27.2) branches per plant, shoot dry matter (4000 kg ha-1) and root dry matter (354 kg ha-1) which were significantly higher than that of 0 and 15 kg P2O5 ha-1 and at par with 20 kg P2O5 ha-1. Similar results were observed in case of crop growth rate (CGR) whereas relative growth rate (RGR) was not influenced significantly by various biofertilizer and phosphorus treatments. The dual inoc-ulation with PGPR strains along with phosphorus application have a supplementary effect on the growth of chickpea.

Phosphorus Application

The experiment was conducted to study the effect of four levels of phosphorus (0, 20, 30 and 40 kg P2O5 ha-1) and four biofertilizer treatments [uninoculated control, Rhizobium, plant growth promoting rhizobacteria (PGPR) and Rhizobium + PGPR] on growth and grain yield of lentil. The experiment was conducted in factorial randomized complete block design (RCBD) with three replications. The periodic data recorded at 30, 60, 90, 120 days after sowing (DAS) and at harvest showed that the highest growth in various parameters i.e. plant height, branches plant-1 and shoot dry matter accumulation was recorded with application of 40 kg P2O5 ha-1, however, it was at par with 30 P2O5 ha-1. Among the biofertilizers, Rhizobium + PGPR treatment gave maximum values of growth parameters like plant height, branches plant-1 and shoot dry matter accumulation at all the stages. At 30-60 DAS, the maximum crop growth rate (CGR) was recorded with the application of 40 kg P2O5 ha-1 (71.3 kg ha-1 day-1) and co-inoculation of Rhizobium and PGPR (72.0 kg ha-1 day-1). Application of 40 P2O5 ha-1 and use of coinoculation (Rhizobium + PGPR) provided the highest grain yields. The study highlights the importance of phosphorus application and biofertilizers inoculation for improving the growth and grain yield of lentil.

A field experiment was carried out at the experimental farm of Soil Salinity Research Institute, Pindi Bhattian during 2016-17 to assess evaluate different Rhizobial inoculation methods on growth and yield of rice (Oryza sativa) cv. Basmati-385 under naturally salt-affected soil (pH= 8.12, ECe= 7.88 dS m-1and SAR=24.96). Seeds of rice were inoculated with Biozote–Max (Plant Growth Promoting Rhizobacteria-PGPR) produced in Soil Biology and Biotechnology Research Programme of Land Resources Research Institute, National Agricultural research Centre (NARC), Islamabad under PARC-Agrotech. Company (Pvt) Ltd. NARC, Islamabad in three ways i.e. rice seeds inoculated for direct seeding and nursery and dipping seedling roots in the solutions of these rhizobial strains comparable of control un-inoculated (control) by each inoculation method. The performances of Rhizobial strain Biozote–Max used as seed and seedling root dipping inoculation were superior to uninoculated control in all the parameters of the rice crop. Among the treatments, seed and seedling root dipping inoculation with Rhizobial strain Biozote–Max performed best in recording plant height, panicle length, number of tillers, 1000-grain weight and grain yield of rice crop. Maximum tillering was observed with all strains under different inoculation methods. Although, the strains performed better as compared to control, however, dipping of nursery roots produced significantly higher yield followed by seed inoculation for direct seeding. Overall, among all the inoculation methods seedling root dipping produced comparable paddy yield. The highest paddy yield (367 g m-2) was harvested with SBCC (M8) seed inoculation which was 13% more than that of un-inoculated (control).
