“…The exact mechanism by which PGPR stimulate plant growth is not clearly established, although several hypotheses are usually believed to be involved. The data of Table 2 and our results agree with the findings of Zafar et al, (Zafar, Abbasi, Khaliq, & Rehman, 2011) who have reported that improved plant growth by PGPR. It is well-known that the presence of tryptophan, as the main precursor of auxin, stimulates bacterial IAA biosynthesis (Vacheron et al, 2013).…”

To investigate the effects of seed inoculation with phosphate affecting microorganisms on the quantitative and qualitative traits of two forage sorghum (Sorghum bicolor (L.)), genotypes were investigated during 2011 and 2012 field experiments. The experimental treatments consisted of chemical (triple super phosphate (TP)), and biological P fertilizers [mycorrhizal fungus (Rhizophagus intraradices) (AM) + Pseudomonas fluorescens strain 93 (PB)] as well as sorghum genotypes (Speedfed and Jumbo) factorially arranged on the basis of a randomized complete block design with three replications. The results revealed that seed inoculation by AM fungi and its combined inoculation with PB significantly influenced sorghum growth, P concentration and acid detergent fibre (ADF%). Rhizophagus intraradices appeared to be better adapted for association with sorghum than P. fluorescens strain 93 under the environmental conditions of the experiment. The significant differences in the quantity and quality of the two genotypes as affected by chemical and biological fertilization indicate the importance of selecting the right genotype, which results in higher growth and yields with a better forage quality. Although in most cases, the biological fertilization was the more recommendable, the use of chemical P fertilization up to some level was essential for the production of sorghum forage yield affecting crop quality. It is more beneficial to use the integrated beneficial microorganisms (AM + PB) instead of their single use to achieve better crop growth, yield and nutrient status for both plant and soil health.

“…The greatest shelling percentage was observed at 2 t C ha −1 with 150 kg N ha −1 under deep tillage system. Zafar et al (2011) found that organic + inorganic fertilizer application resulted in a greater shelling percentage than sole application of either. Ali et al (2002) also reported the greatest value for shelling percentage at 150 kg N ha −1 .…”

On-farm research was conducted to investigate the effects of nitrogen (N) and compost (C) on yield and yield components of spring maize (Zea mays L.) under conventional and deep tillage system (T) at the research farm of the University of Agriculture, Peshawar, Pakistan, during spring 2013. The experiment was laid out in a randomized complete block design with split-plot arrangement, using three replications. Three compost levels (0, 1, and 2 t ha −1 ) and two tillage systems (conventional and deep tillage) were allotted to the main plot, whereas N levels (60, 90, 120, and 150 kg N ha −1 ) were allotted to subplots in the form of urea. Nitrogen and compost levels had significantly affected all the parameters. Plots treated with 150 kg N ha −1 increased ear length (31 cm), grains ear −1 (413), thousand-grain weight (240.2 g), grain yield (3097 kg ha −1 ), straw yield (9294 kg ha −1 ), harvest index (24.7 percent), and shelling percentage (81.7 percent). Compost applied at 2 t ha −1 increased ear length (32 cm), grains ear −1 (430), thousandgrain weight (242.3 g), grain yield (2974 kg ha −1 ), straw yield (8984 kg ha −1 ), harvest index (24.6 percent), and shelling percentage (83.2 percent). Tillage system had significant effect on all parameters except ear length and harvest index. Deep tillage system produced more grains ear −1 (365), thousand-grain weight (233.3 g), grain yield (2630 kg ha −1 ), straw yield (8549 kg ha −1 ), and shelling percentage (79.6 percent). It was concluded from the results that application of 120 kg N ha −1 + 2 C t ha −1 under a deep tillage system could improve spring maize yield and yield-contributing traits under semi-arid conditions.

“…There was also a strong connection between P and the maximum rate of photosynthesis [44]; a partial explanation may lie in a positive relationship between the concentration of P and the amount of Rubisco. Inorganic phosphate (Pi) is a prerequisite for RuBP and also a competitive inhibitor of RUBP [45,46]. Additionally, there was a strong correlation between K concentrations and Rubisco [21].…”

Ginkgo biloba L. is one of the most extensively planted and productive commercial species in temperate areas around the world, but slow-growth is the most limiting factor for its utilization. Fertilization is one of the key technologies for high quality and high forest yield. To better understand the impacts of fertilization on Ginkgo productivity, the effects of fertilization treatments (single fertilizer and combined fertilizer) on growth, nutrient content in Ginkgo leaves, and photosynthesis characteristics were studied in a 10-year-old Ginkgo plantation over two years. The single factor experiments suggested that DBH (diameter at breast height), H (height), NSL (length of new shoots), and V (trunk volume) showed significant differences between the different levels of single nitrogen (N) or phosphate (P) fertilizer application. Orthogonal test results showed that the nine treatments all promoted the growth of Ginkgo, and the formula (N: 400 g·tree −1 , P: 200 g·tree −1 , potassium (K): 90 g·tree −1 ) was the most effective. G s (stomatal conductance) and P n (net photosynthesis rate) showed significant differences between the different amounts of single N or P fertilizer application, while single K fertilizer only affected P n . Combined N, P, and K fertilizer had significant promoting effects on C i (intercellular CO 2 concentration), G s and P n . N and P contents in Ginkgo leaves showed significant differences between the different amounts of a single N fertilizer application. A single P fertilizer only improved foliar P contents in Ginkgo leaves. A single K fertilizer application improved N and K content in Ginkgo leaves. The effects of different N, P, and K fertilizer treatments on the nutrient content of Ginkgo leaves were different.
