“…The genus Azolla belongs to the division of symphytes, class Ferns, and order Salviniales) of the family Salviniaceae and has two sub-genera and six viviparous species (Roy et al 2016) This study demonstrated that the use of azolla fertilizer as a single or combination application can reduce the use of synthetic fertilizers by up to 60% without significant reduction in growth and yield of rice grains. (Seleiman et al 2022) Azolla is used as an organic fertilizer for its high nitrogen content that enhances crop yield and soil quality as well as being an environmentally friendly practice (Braun-Howland and Nierzwicki-Bauer, 2018). Root nodes and nitrogen fixation, which affects the growth and production of legumes (Al-Saadi 2001), as Al-Kartani et al (2018) indicated that the inoculation of the mung plant with Bradyrhizobium sp.…”

A field experiment was carried out in a randomized complete block design (R.C.B.D) to study the effect of inoculation with R. leguminosarum at two levels (with and without inoculation) and The compost made from the azolla plant and the interaction between them in efficiency of the root nodule formation and growth and yield of the faba bean plant grown in gypsiferous soil after being isolated and identificated by phenotypic, biochemical and molecular methods, the results showed that there was a significant increase in all plant characteristics of the fertilized and inoculated treatments compared to the non-inoculated treatment, as outperformed the compost treatment with azolla on the control treatment in all growth and yield traits, and significantly superior the inoculation treatment with Rhizobuim leguminosarum in all studied traits compared to the control treatment, and gave the inoculation treatment with Rhizobuim leguminosarum and compost made from the azolla the highest values compared to the control treatment, as the averages were in the number of root nodules, their wet weight and number of the bacteria surrounding the roots (15,000, 2.274 and 6.400 x 104), the plant height and the dry weight of the vegetative part (39,000, 24.995), (gm plant-1 cm plant-1 ) and concentration of the nitrogen, phosphorous and potassium in the vegetative part (1487, 238 and 1819) ppm respectively.

“…The addition of N can significantly affect the concentration of N and P in green and old leaves and the pattern of nutrient resorption [41]. Based on the results of this study, it shows that organic fertilizers have complete nutrition and contain growth regulators such as hormones for plant growth [43]. The results showed that the compost dose had a significant effect on the content of chlorophyll a, but had no effect on the content of chlorophyll b and total (Table 4).…”

Expanding sustainable agriculture approaches is critical to increase crop growth and productivity. This farming system should involve organic fertilization and not neglect the recycle of organic waste. One of the organic wastes that can be used as compost is Indigofera tinctoria natural dye waste. The research objective was to examine the vegetative growth response of corn plants to Indigofera tinctoria compost. The design used was a complete randomized block design with one factor of fertilization doses with 3 six levels namely 2.91; 5.83; 8.75; 11.67; 14.58 tons/ha, and chemical fertilizers as controls. Indigofera tinctoria compost meets the standards as organic fertilizer according to the Ministry of Agriculture with characteristics of 18.2% water content, 52.48% organic C, 90.48% organic matter, 2.84% total nitrogen, 1.54% total phosphate, total potassium 2.44%, 1.30% available nitrogen, 0.92% available phosphate, 1.52% available potassium and 60 cmol/kg cation exchange capacity. The dose of compost significantly affected on plant height of 2-4 WAP, stem diameter of 2 WAP , and root biomass of 2 WAP. The compost dose of 5.83 tons/ha has increased root growth and plant height.

“…Moreover, it has been demonstrated that the application of zeolite compounds along with nitrifying bacteria increased crop biomass and NUE while decreasing the ammonia volatilization N losses ( Cataldo et al, 2021 ). The application of organic manures, such as rice straw and synthetically manufactured composts like Azolla compost, significantly increased the concentration of total soil N pools and also improved the soil structure and nutrient recycling ( Bagheri Novair et al, 2020 ; Seleiman et al, 2022 ).…”

Rice (Oryza sativa L.) is considered as a staple food for more than half of the global population, and sustaining productivity under a scarcity of resources is challenging to meet the future food demands of the inflating global population. The aerobic rice system can be considered as a transformational replacement for traditional rice, but the widespread adaptation of this innovative approach has been challenged due to higher losses of nitrogen (N) and reduced N-use efficiency (NUE). For normal growth and developmental processes in crop plants, N is required in higher amounts. N is a mineral nutrient and an important constituent of amino acids, nucleic acids, and many photosynthetic metabolites, and hence is essential for normal plant growth and metabolism. Excessive application of N fertilizers improves aerobic rice growth and yield, but compromises economic and environmental sustainability. Irregular and uncontrolled use of N fertilizers have elevated several environmental issues linked to higher N losses in the form of nitrous oxide (N2O), ammonia (NH3), and nitrate (NO3–), thereby threatening environmental sustainability due to higher warming potential, ozone depletion capacities, and abilities to eutrophicate the water resources. Hence, enhancing NUE in aerobic rice has become an urgent need for the development of a sustainable production system. This article was designed to investigate the major challenge of low NUE and evaluate recent advances in pathways of the N cycle under the aerobic rice system, and thereby suggest the agronomic management approaches to improve NUE. The major objective of this review is about optimizing the application of N inputs while sustaining rice productivity and ensuring environmental safety. This review elaborates that different soil conditions significantly shift the N dynamics via changes in major pathways of the N cycle and comprehensively reviews the facts why N losses are high under the aerobic rice system, which factors hinder in attaining high NUE, and how it can become an eco-efficient production system through agronomic managements. Moreover, it explores the interactive mechanisms of how proper management of N cycle pathways can be accomplished via optimized N fertilizer amendments. Meanwhile, this study suggests several agricultural and agronomic approaches, such as site-specific N management, integrated nutrient management (INM), and incorporation of N fertilizers with enhanced use efficiency that may interactively improve the NUE and thereby plant N uptake in the aerobic rice system. Additionally, resource conservation practices, such as plant residue management, green manuring, improved genetic breeding, and precision farming, are essential to enhance NUE. Deep insights into the recent advances in the pathways of the N cycle under the aerobic rice system necessarily suggest the incorporation of the suggested agronomic adjustments to reduce N losses and enhance NUE while sustaining rice productivity and environmental safety. Future research on N dynamics is encouraged under the aerobic rice system focusing on the interactive evaluation of shifts among activities and diversity in microbial communities, NUE, and plant demands while applying N management measures, which is necessary for its widespread adaptation in face of the projected climate change and scarcity of resources.
