“…The lowest values of nitrogen, phosphorus and potassium contents (1.50, 0.19 and 1.52%,) were found with control (80 kg N fed -1 ), while, compost + 50% of the control treatment scored the highest values (1.63, 0.28 and 2.11%), respectively. The aforementioned findings correlated with those recorded by Gupta, (2010); Gupta, et al (2011);Khaled & Fawy(2011) and Kumar, et al (2012 and2013) who reached the same results. In this subject, they revealed that increase in K% of stevia leaf by compost application might be due to enhancement in K availability by shifting the equilibrium among the forms of K from relatively exchangeable K to soluble K forms in the soil.…”

Stevioside is natural sweetener isolated from the leaves of plant stevia and it is up to 300 times sweetener than sucrose, since it is a sweetener with no caloric value and with proven non-toxic effect on human health. Steviol glycosides are used as a sweetener in many industrial foods, such as soft drinks or fruit juices. So, two field experiments were conducted at Mallawi Agricultural Research Station, El-Minia Governorate during 2014 and 2015 seasons to deduce the effect of different sources of nutrient, i.e. Control (80 kg N fed -1 ), K-humate + (40 kg N fed -1 ), biofertilizer +(40 kg N fed -1 ) and compost + (40 kg N fed -1 )] and number of cutting , i.e. 1 st , 2 nd and 3 rd cutting on yield and quality of stevia (Stevia rebaudianaBertoni) under Middle Egypt conditions. The obtained data pointed out that different sources of nutrient had a significant effect on plant height, fresh plant weight, dry plant weight, fresh leaves weight/plant, dry leaves weight/plant, N, P and K % of stevia leaf, fresh biomass yield, dry biomass yield , fresh leaves yield, dry leaves yield and fresh stem yield, total stevioside % (St %), rebaudioside A% (Rb%), stevioside yield and rebaudioside A yield of stevia in two growing seasons.The studied cutting number of stevia had a significant influence on plant height, fresh plant weight, dry plant weight, fresh leaves weight/plant, dry leaves weight/plant, dry leaves weight: dry stem weight, P % of stevia leaf, fresh biomass yield, dry biomass yield, fresh leaves yield, dry leaves yield and fresh stem yield and dry stem yield of stevia, rebaudioside A%, total stevioside yield (kg/fed) and rebaudioside A yield (kg/fed) of stevia rebaudiana in two growing seasons. From the present study, it may be concluded that the application of compost at 2.0 ton/fed+(40 kg N fed-1) with 3 rd cutting was the best treatment for improving the yield and quality of stevia (Stevia rebaudianaBertoni) and is advisable because it is achieved the highest value of rebaudioside A(102.80 kg/fed) of stevia. This helps in reducing the great gap in sugar production, which amounted to 0.7 million tons between production and sugar consumption at the national level production under the experimental conditions.

“…and B. lentus signifi cantly increased proline, total carbohydrate, chlorophyll, and nutrient uptake under water stress. Gupta et al ( 2011 ) evaluated the prospective uses of phosphate-solubilizing bacterial strains such as Burkholderia gladioli , B. gladioli , Enterobacter aerogenes , and Serratia marcescens to utilize Mussoorie rock phosphate and to improve the growth of Stevia rebaudiana and secondary metabolites (stevioside and rebaudioside A). They concluded that a signifi cant increase in plant growth and metabolite production (stevioside and rebaudioside A) was recorded in the plants treated with combination of bacterial strains grown in Mussoorie rock phosphate amended soil compared to unamended soil.…”

Plant growth-promoting rhizobacteria (PGPRs) are a group of naturally occurring benefi cial soil bacteria that colonize with the plant root system and promote growth by triggering the production of growth-regulating substances and facilitate the plants in the uptake of essential nutrients from the surrounding environments. Similarly, arbuscular mycorrhizal (AM) fungi also enhanced the growth, water and nutrient uptake, and especially available phosphate through their specialized hyphae. In addition, PGPR and AM fungi are known to stimulate the accumulation of secondary metabolites in plants. For several years, they are commonly employed to increase the plant yield and productivity especially in agricultural practices. The medicinal and aromatic plants are gaining popularity worldwide due to high therapeutic properties with negligible toxic side effects. To fulfi ll the global demand and supply gap for medicinal and aromatic plants and their products, farmers are encouraged to cultivate these plants on a large scale. However, there is a need to understand and implement a better cultivation practices in order to improve the quality of medicinal and aromatic plants. In this regard, the utilization of PGPRs and AM fungi as biofertilizers instead of chemical fertilizers could be a promising approach to the development of medicinal and aromatic plants under the sustainable production system. The aim of this chapter is to describe the potentiality of PGPRs and AM fungi to improve growth and development of medicinal and aromatic plants and accumulation of secondary metabolites having high therapeutic worth and also pave a way in the development of new biotechnological products as biofertilizers.

“…Among these, organic amendments, including animal manure, plant residues and green manure (Alloush, 2003;Toor, 2009;Aria et al, 2010;Adesanwo et al, 2012), composts (Nishanth and Biswas, 2008;Wickramatilake et al, 2010;Saleem et al, 2013), and bacterial inoculation (Panhwar et al, 2011;Gupta et al, 2011) are considered beneficial for improving the P efficiency. In addition, the combined application of water-soluble P fertilizers with RP is another option to increase the efficiency of RP P. Mashori et al (2013) used maize as a test crop in a pot experiment to examine the relative performance of RP, single superphosphate (SSP) and RP+SSP with and without farm yard manure (FYM).…”

Abstract. The ability of soil microorganisms and organic manure to convert insoluble phosphorus (P) to an accessible form offers a biological rescue system for improving P utilization efficiency in soil-plant systems. Our objective was to examine the P mineralization potential of two soluble P fertilizers (SPF), i.e., single superphosphate (SSP) and diammonium phosphate (DAP), and of insoluble rock phosphate (RP) with and without phosphate-solubilizing bacteria (PSB) and poultry manure (PM) and their subsequent effect on the growth, yield and P utilization efficiency (PUE) of chilli (Capsicum annuum L.). An incubation study was carried out on a loam (slightly alkaline) soil with 12 treatments: T 0 -control; T 1 -RP; T 2 -SSP; T 3 -DAP; T 4 -PM; T 5 -1/2 RP+1/2 SSP; T 6 -1/2 RP+1/2 DAP; T 7 -1/2 RP+1/2 PM; T 8 -RP+PSB; T 9 -1/2 RP+1/2 SSP+PSB; T 10 -1/2 RP+1/2 DAP+PSB; and T 11 -1/2 RP+1/2 PM+PSB. Phosphorus mineralization was measured by analyzing extractable P from the amended soil incubated under controlled conditions at 25 • C for periods of 0, 5, 15, 25, 35 and 60 days. A complementary greenhouse experiment was conducted in pots with chilli (Capsicum annuum L.) as a test crop. Growth, yield, P uptake and PUE of the chilli was determined during the study. Results indicated that P mineralization in soil amended with RP was 6.0-11.5 mg kg −1 , while both soluble P fertilizers resulted in 68-73 mg P kg −1 at day 0, which decreased by 79-82 % at the end of incubation. The integrated use of PSB and PM with RP in T 11 stimulated P mineralization by releasing a maximum of 25 mg P kg −1 that was maintained at high levels without any loss. Use of PSB decreased soil pH. In the greenhouse experiment, RP alone or RP+PSB did not have a significant impact on plant growth. However, the combined use of RP, PM and PSB in T 11 resulted in similar growth, yield and P uptake of chilli as DAP. The PUE of applied P varied from 4 to 29 % and was higher in the treatments that included PSB. We conclude that the use of PSB and PM with insoluble RP or with soluble P fertilizers could be a promising approach to enhance P availability from both low-grade RP and SPF for crop production in intensive cropping systems.
