“…Inoculation with phosphate solubilizing bacteria high significantly increased dry shoot and fruits per plant (226.65, 213.86) and (6.09, 6.08) compared to (215.04, 194.28) and (5.34, 5.5) g/plant in the first and second seasons, respectively. These results are in agreement with those obtained by Sreedevi Sarsan (2016). The interaction effect between phosphorus levels and salicylic spraying was highly significant on tomato dry shoot weight (g/plant), where the highest values were obtained with 15 kg P 2 O 5 + salicylic spraying.…”

“…Data in Table (5) show that biofertilizer inoculation high significantly increased fruit length, fruit diameter and average fruit weight in both seasons compared to uninoculated one. These results are in harmony with those obtained by Sreedevi Sarsan (2016). No significant differences in fruit length, fruit diameter and average fruit weight except average fruit weight in the second season, due to the interaction between phosphorus levels at 15 kg P 2 O 5 and salicylic spraying.…”

The objective of the present study is to investigate effect of phosphorus fertilizer levels and potassium salicylate spraying on tomato growth, yield, quality and curly top virus severity % (TCTV) and incidence. Two field experiments were conducted in a private farm at El-Shamarka, Kafr El-Sheikh district, Kafr El-Sheikh governorate during 2014 and 2015 seasons. Split split plot design was used with four replicates. The main plots were assigned with three phosphorus levels 0, 15 and 30 kg P 2 O 5 fed -1 . The sub plots were assigned with two potassium salicylate treatments of without potassium salicylate but sprayed by potassium 20% K 2 O 1 liter in 200 liter water fed -1 and spraying with potassium salicylate 20% K 2 O, 12.5% salicylate at the rate 300 mg L -1 salicylic of the spraying solution. The sub sub plots were assigned with two biofertilizer treatments of without inoculation and inoculation with phosphate solubilizing bacteria. The results can be summarized as phosphorus at the level of 15 kg P 2 O 5 fed -1 had the highest values of stem length, number of branches/plant, leaves area/plant, dry weight of shoot/plant and total yield (15.39, 16.15 ton fed -1 ) and vitamin C. While, the phosphorus level of 30 kg P 2 O 5 fed -1 had the highest values of early yield (4.51 and 4.39 ton fed -1 ) fruit length, fruit diameter, average fruit weight, TSS, acidity, N%, K% in the shoot and fruits. Potassium salicylate spraying had the highest values of stem length, number of branches/plant, leaves area/plant, dry shoot, dry fruit/plant, early and total yield ton fed -1 , average fruit weight, TSS, acidity, vitamin C and K% in fruits. Phosphate solubilizing bacteria inoculation increased stem length, leaves area/plant, dry shoots and fruit weight, early and total yields, fruit length, fruit diameter, average fruit weight, TSS, acidity and vitamin C, N%, K% in the shoot and fruits. Phosphorus at the level 15 kg P 2 O 5 fed -1 affected curly top virus (TCTV), decreased disease incidence %, disease severity % and increased reduction infection %. Disease severity comparing to the used rating scale (0-4) all the values of P levels from 12.21 up to 19.95% lies in class one (11-20%), this means that effect of P levels on (TCTV) was low. Potassium salicylate spraying decreased disease incidence %, disease severity % and increased reduction infection %. Comparing with the used rating scale clear that the values of K-salicylate (4.43, 9.75%) lies in the class zero (0-10%), while the control (21.79, 25%) lies in class two (21-30%), this means that Ksalicylate spraying was effective in decreasing (TCTV) in tomato.

“…Lowest mean number of fruits length was obtained by the control plant without fertilizer and experimental plant without fertilizer which was also significant with p<0.05. A similar study conducted by Sreedevi Sarsan (2016) [27] showed significant plant yield parameters in tomato with PSB stain. Comparison of the mean weight of fruits obtained from okra plant, whereby the mean weight of fruits obtained from inoculated plants is higher compared to uninoculated plants shown in figure 6.…”

Phosphorus (P) is a major growth limiting nutrient. Phosphate Solubilizing Bacteria (PSB) plays an important role in the development of agricultural industry. In this study, the native PSB were isolated from the okra plant root by using Pikovskaya’s medium and potential strains were selected based on the phosphate solubilization efficiency. The potential strains in presence of Rock Phosphate (RP), Tea dust, Eggshells and Bone waste of animal (TEB) were studied as an alternative fertilizer instead of chemical fertilizer. The PSB consortia strains were prepared and inoculated to the plant root. Different growth parameters were studied to determine the effectiveness of strains. In all cases the difference was significant with p<0.05. A decreasing trend of results were recorded among the tested parameters from plants in PSB with RP, PSB with TEB, and PSB with TSP and followed by PSB without fertilizer. The highest results were recorded among plants in PSB with RP for mean shoot length (64cm), mean weight of fruits (29gm), mean length of fruits (23cm), mean number of leaves (13Nos) and chlorophyll content (5.1mg/g). Hence, the present study showed that the application of PSB with the cheap source of nutrients has shown the capability of providing similar or enhanced results based on the various characters expressed by the plant and thus reduce the reliance on synthetic chemical fertilizers.

“…The majority of the previous studies have largely described the direct effects of PSBs on plant growth based essentially on P solubilization and plant growth (Manzoor et al, 2017;Singh et al, 2018;Liu et al, 2019). Other studies have also reported important beneficial effects on few root parameters (Sarsan, 2016;Suleman et al, 2018;Rezakhani et al, 2019) with no strong linkage with aboveground P-related parameters. However, this study provided new evidence that PSB effects are not basically restricted to P solubilization alone, but extend to multiple known and unknown indirect effects on morphological root traits, thus improving both acquisition and internal use of P. Multiple differential responses at the level of "PSBplant" interactions are reported herein, notably the significant increase of the rhizosphere P availability due to PSB inoculation (Table 1) at an early stage of plant development (7-day old seedlings), which could provide adequate amount of P readily available for the continuously growing roots, thus a better plant growth and P nutrition presumably secured for the subsequent growth stages.…”

“…This will help understand how tight the relationship between the PSB of interest and the rooting system under sparingly P forms is and whether it always remains tight throughout the different plant growth stages, considering that highly performing PSB in vitro are presumably the most efficient in planta. Another important aspect of a successful PSB-root interaction would be the best fit in terms of rooting stimulation in addition to rhizosphere P solubilization that most studies have focused on as only few investigations (Bakhshandeh et al, 2015;Sarsan, 2016;Rezakhani et al, 2019) described a positive influence on specific root functional traits. This is in line with the objective of this study to assess the effect of five P solubilizing rhizobacteria exhibiting different PSC "low, medium and high" on durum wheat morphological root traits and associated rhizosphere P solubilization in order to shed light on how tight does inoculation link rhizosphere parameters with plant aboveground morphological and physiological traits under RP fertilization.…”

Phosphate Solubilizing Rhizobacteria Could Have a Stronger Influence on Wheat Root Traits and Aboveground Physiology Than Rhizosphere P Solubilization

Limited P availability in several agricultural areas is one of the key challenges facing current agriculture. Exploiting P-solubilizing bacteria (PSB) has been an emerging bio-solution for a higher rhizosphere P-availability, meanwhile the above-and below-ground interactions that PSB would trigger remain unclear over plant growing stages. We hypothesized that PSB effects on plant growth may be greater on root traits that positively links with aboveground physiology more than the commonly believed rhizosphere P bio-solubilization. In this study, five contrasting PSB (Pseudomonas spp.) isolates (low "PSB 1 ", moderate "PSB 2 and PSB 4 " and high "PSB 3 and PSB 5 " P-solubilizing capacity "PSC") were used to investigate aboveand below-ground responses in wheat fertilized with rock P (RP) under controlled conditions. Our findings show that all PSB isolates increased wheat root traits, particularly PSB 5 which increased root biomass and PSB 3 that had greater effect on root diameter in 7-, 15-and 42day old plants. The length, surface and volume of roots significantly increased along with higher rhizosphere available P in 15-and 42-day old plants inoculated with PSB 4 and PSB 2. Shoot biomass significantly increased with both PSB 2 and PSB 5. Root and shoot physiology significantly improved with PSB 1 (lowest PSC) and PSB 4 (moderate PSC), notably shoot total P (78.38%) and root phosphatase activity (390%). Moreover, nutrients acquisition and chlorophyll content increased in inoculated plants and was stimulated (PSB 2 , PSB 4) more than rhizosphere P-solubilization, which was also revealed by the significant above-and below-ground inter-correlations, mainly chlorophyll and both total (R = 0.75, p = 0.001**) and intracellular (R = 0.7, p = 0.000114*) P contents. These findings demonstrate the necessity to timely monitor the plant-rhizosphere continuum responses, which may be a relevant approach to accurately evaluate PSB through considering below-and above-ground relationships; thus enabling unbiased interpretations prior to field applications.
