Roselle (Hibiscus sabdariffa L.) is one of the most crucial medicinal plants all over the world. The present study was carried out with the intention of solving some problems related to soil-borne diseases. Fusarium oxysporum is associated with wilt disease of roselle plant. The application of some microbiota i.e., a mixture of Pseudomonas fluorescens (PSR-11), Bacillus subtilis (BSR-8), Pleurotus ostreatus and mycorrhizeen® individually or in combination were investigated for controlling wilt disease, growth, and yield of roselle plant. The study was conducted in sandy textured soil under sprinkler irrigation of Ismailia Agricultural Research Station, Ismailia, Egypt. Under greenhouse conditions, all the tested bioagents reduced wilt incidence and increased the percentage of survived plants. The conglomeration of the bacterial mixture of Pseudomonas fluorescens and Bacillus subtilis, Pleurotus ostreatus and mycorrhizeen® was more effective in controlling wilt disease than using any of them individually. The application of the investigated bioagents showed a significant increase in phenol, photosynthetic pigments, and dehydrogenase contents, as well as root colonization percent. The obtained results showed the ability of B. subtilis and P. fluorescens to produce lytic enzymes such as β-1-3 glucanase, β-1-4 glucanase, chitinase and protease, in addition to their production of siderophore and HCN. The consortium of all microbiota gave the best results for growth and yield parameters of roselle plant.

“…Besides, understanding rice response to lime application in acid paddy soils is of great importance for attaining yield potential to meet the dynamic of population development. It has been widely reported that lime application in acid soils greatly improves crop productivity directly through enhancing soil physical, chemical, and biological properties, which ultimately increase the availability and mobility of plant essential nutrients (Chan and Heenan 1998;Bolan et al 2003;Jaskulska et al 2014;Al-Sayed et al 2020;Rekaby et al 2020). Besides, the increase in rice grain yield in acid soils in response to liming was mainly ascribed to the increase in soil pH which drastically decreases aluminum toxicity and promoted the absorption of Ca, Mg, P, and K (Rahman et al 2005;Goswami et al 2008;Previna and Baskar 2012;Fageria and Nascente 2014;Crusciol et al 2016;Zeng et al 2017).…”

“…Soil pH is extremely important for the activity and adsorption of toxic metals in the soil (Dinesh and Kumar 2006;Adhikari and Singh 2008;Choppala et al 2013;Azouzi et al 2015). Therefore, since most of these toxic metals are less soluble under alkaline conditions, increasing soil pH has become a common procedure for repairing heavy metal-contaminated soils (Adriano 2001;Eissa et al 2016;Eissa 2019;Almaroai and Eissa 2020). However, if the soil pH is too high it would cause dissolution of heavy metals.…”

Lime application is the most effective agricultural practice for the reduction of cadmium (Cd) bioavailability in acid soils. This study was conducted to investigate the impact of continuous liming across five consecutive growing seasons on the remediation of Cd in acid paddy soils, as well as rice yield. Two rice cultivars, i.e., Zhuliangyou 819 and Xiangwanxian 12, were cultivated in Cd-contaminated paddy soil for five consecutive growing seasons from 2014 to 2018. The investigated lime levels were 0, 450, 900, 1350, 1800, 2250, 3000, and 3750 kg ha −1. Lime application significantly increased rice yield, soil pH, exchangeable soil Ca 2+ , and rice calcium (Ca) contents; besides, it reduced soil and rice Cd contents. The application of lime at the rate of 1350-2250 kg ha −1 significantly increased rice yield. Under continuous liming, rice yield obviously increased first and then decreased with the cumulative application of lime. The application of a cumulative lime amount of 18,000 kg ha −1 was identified as the critical transition point of soil pH, soil Cd, and rice Cd content. Application of lime up to or above 3000 kg ha −1 per season reduced Cd content in brown rice below 0.20 mg kg −1. The results suggest that the reduction in effective Cd content might be a result of the combined action of exchangeable soil Ca 2+ and soil pH rather than being a direct effect of Ca 2+. Therefore, acid Cdcontaminated paddy fields can realize the safe production of rice by the continuous application of an appropriate amount of lime.

“…The applications of N fertilizers are normally split for maximum rice production in China, with 2-4 top dressings as broadcast application during each crop season, but this often result in very low NUEs, severe N loss, and environmental contamination (Peng et al 2002;Almaroai and Eissa 2020;Al-Sayed et al 2020;Rekaby et al 2020). Although NH 3 volatilization has been reported in Chinese double rice-cropping system under long-term fertilization (Shang et al 2014), but few literatures have been showed the impacts of controlled release forms on NH 3 volatilization in double-cropping rice grown in paddy soils.…”

Controlled-release nitrogen fertilizer (CRNF) can effectively enhance crop yields and raise the efficiency of nitrogen fertilizer in agroecosystems. In the present study, the volatilization of NH3 was determined by airflow enclosure chamber technique after the application of different CRNF rates in double-cropping rice fields in southern China for continuous 3 years. The early and late season rice (ESR and LSR) were cultivated each year. The results showed that the total NH3 volatilization losses ranged from 25 to 56 kg N ha−1 in ESR and from 32 to 61 kg N ha−1 in LSR. The loss of N to the total applied N ranged from 12 to 29% in ESR and from 12 to 27% in LSR. The application of CRNF significantly reduced the cumulative NH3 volatilization losses by 20–43% for ESR and by 20–32% for LSR compared with conventional urea application. CRNF in LSR was less effective to reduce NH3 volatilization than that in ESR. Furthermore, the application of 80% of N rate in the form of CRNF gave higher grain yield and apparent nitrogen recovery efficiency (ANRE) than that of application of 100% of N rate from conventional urea. CRNF can effectively reduce NH3 volatilization, and increase rice yield and ANRE. Considering higher price of CRNF, the application of CRNF at lower (20% applied N) rate than conventional urea in LSR may be a reasonable fertilization strategy for improving N use efficiency, environment effectiveness, and sustaining the development of rice production systems in double-cropping rice.
