Enrichment of staple food with zinc (Zn) along with solubilizing bacteria is a sustainable and practical approach to overcome Zn malnutrition in human beings by improving plant nutrition, nutrient use efficiency, and productivity. Common bean (Phaseolus vulgaris L.) is one of a staple food of global population and has a prospective role in agronomic Zn biofortification. In this context, we evaluated the effect of diazotrophic bacterial co-inoculations (No inoculation, Rhizobium tropici, R. tropici + Azospirillum brasilense, R. tropici + Bacillus subtilis, R. tropici + Pseudomonas fluorescens, R. tropici + A. brasilense + B. subtilis, and R. tropici + A. brasilense + P. fluorescens) in association with soil Zn application (without and with 8 kg Zn ha−1) on Zn nutrition, growth, yield, and Zn use efficiencies in common bean in the 2019 and 2020 crop seasons. Soil Zn application in combination with R. tropici + B. subtilis improved Zn accumulation in shoot and grains with greater shoot dry matter, grain yield, and estimated Zn intake. Zinc use efficiency, recovery, and utilization were also increased with co-inoculation of R. tropici + B. subtilis, whereas agro-physiological efficiency was increased with triple co-inoculation of R. tropici + A. brasilense + P. fluorescens. Therefore, co-inoculation of R. tropici + B. subtilis in association with Zn application is recommended for biofortification and higher Zn use efficiencies in common bean in the tropical savannah of Brazil.

Aims: Investigated the influence of organic manures (municipal solid waste compost [MSWC] and cow dung) and N-fertilizer on growth, yield and nutrient use efficiency of jute mallow (Corchorus olitorius L.) under two water regimes (rain-fed and irrigated). Study Design: Randomized complete block. Place and Duration of Study: Farm of Faculty of Agricultural Sciences, University of Parakou, Northern Benin (latitude 09°20’16.8’’N and longitude 002°38’54’’ E, 353 m asl), during 2013 rainy (June to August) and dry seasons (October to December 2013). Methodology: Ten treatments derived from a factorial combination of five levels of organic manures (control, MSWC at 10 t/ha, MSWC at 20 t/ha, cow dung at 10 t/ha and cow dung at 20 t/ha) and two levels of N-fertilizer (0 kg and 50 kg urea/ha), arranged in a randomized complete block with three replicates were considered. Results: Results showed that water regime significantly (p<.001) affected growth and yield of jute mallow. In addition, the growth and yield parameters showed significant differences (p<.001) in relation to different rates of organic manures.  The integrated use of organic manure and urea increased plant height, number of leaves, stem diameter, number of branches, leaf growth parameters and leaf yield. The maximum amount of leaf yield (7554.88 kg/ha) was obtained with 20 tons/ha of MSWC and 50 kg urea/ha. Conclusion: Fertilizer types also had highly significant effects on nutrient use efficiency. Application of these treatments could help to enhance yield and growth of the jute mallow.

The primary objective of this review study was to determine the best irrigation and fertilizer scheduling practice in order to achieve maximum yield with maximum water and fertilizer use efficiency and highest nutrient uptake. It is found nutrient use efficiency could be as high as 90 per cent in fertigation as compared to 40 to 60 per cent in conventional methods. The amount of fertilizer lost through leaching can be as low as 10 per cent in fertigation whereas it is 50 per cent in the traditional system. It is observed that irrigation and fertigation scheduled at 75% ET and at 75% RDF, respectively could be a good alternate for saving water and nutrients with enhanced nutrient uptake, growth, yield and quality of crops. In this paper, the literature pertaining to the different aspects of fertigation and irrigation scheduling are reviewed.

The application of Nano micronutrient fertilizers could improve nutrient use efficiency that reduces the dosage of NPK fertilizers. This study aims to find out the best combination of NPK and Nano micronutrients fertilizers on growth, yield and quality of red hot chilli pepper. A field study was conducted on chilli (Capsicum annuum L.) fertilized by different NPK fertilization levels (0.0, 50, 75 and 100% of recommended levels) and sprayed by different Nano micronutrients rates (0.0, 0.25 and 0.50 g/l) during the two summer consecutive seasons of 2017 and 2018 at Agriculture Research. Farm (Ghazala Farm), Faculty of Agriculture., Zagazig University., Egypt, The recommended dosage was 218. N+ 36 P +142 K kg/ha and Nano-micronutrient fertilizer that was used contained (6% Fe, 6% Zn, % B, 5% Mn, 1% Cu and 0.1% Mo). The experimental design was a split-plot arranged in a three replicates. The main plots were assigned for four NPK fertilization levels and sub plot were devoted for three Nano-micronutrients rates. The results pointed out that the vegetative growth significantly increased by NPK fertilization at 100 or 75% RLs as well as Nano-micronutrients at 0.5 g/l rate and in combination compared to control (0NPK, 0 Nano-micronutrients). Yield components and chemical constituents were increased gradually by increased NPK fertilizers levels during the two seasons. The best combination treatment in this connection was 100% RLs of NPK fertilizers combined with 0.5 g/l of Nano-micronutrients compared to the other ones under study that increased the yield and capsaicin by 75% of NPK and 0.5 g/l of Nano than control, respectively.

Aquaponics combines the hydroponic production of plants and the aquaculture production of fish into a sustainable agriculture system that uses natural biological cycles to supply nitrogen and minimizes the use of nonrenewable resources, thus providing economic benefits that can increase over time. Several production systems and media exist for producing hydroponic crops (bench bed, nutrient film technique, floating raft, rockwool, perlite, and pine bark). Critical management requirements (water quality maintenance and biofilter nitrification) for aquaculture need to be integrated with the hydroponics to successfully manage intensive aquaponic systems. These systems will be discussed with emphasis on improving sustainability through management and integration of the living components [plants and nitrifying bacteria (Nitrosomonas spp. and Nitrobacter spp.)] and the biofilter system. Sustainable opportunities include biological nitrogen production rates of 80 to 90 g·m−3 per day nitrate nitrogen from trickling biofilters and plant uptake of aquaculture wastewater. This uptake results in improved water and nutrient use efficiency and conservation. Challenges to sustainability center around balancing the aquaponic system environment for the optimum growth of three organisms, maximizing production outputs and minimizing effluent discharges to the environment.

Npk Fertilization

Currently, there are some doubts regarding fertilization dimensioning that aims at a high grain yield in soils with improved fertility in a crop rotation system. Thus, the objective of this study was to evaluate the yield and profitability resulting from different combinations of NPK fertilization andthe efficiency of these nutrients in sequential crops of corn/soybean/corn, in a Latosol with improved fertility, in a farm located in the region of Campo das Vertentes, Minas Gerais State, Brazil. Four doses of sowing fertilization and topdressing were compared, corresponding to approximate proportions of 25, 50, 100 and 150 % of the doses usually applied by farmers. Nutrients sources varied according to the inputs used in the farm for each crop. In a soil with improved fertility, corn is more responsive tofertilization than soybean, with higher grain yield gains associated with N and K supply, while P is less limiting. The most profitable nutrients combination for this system involves increasing the amounts of N and K and reducing the amount of P in relation to the standard fertilization employed on the farm, providing a 14.3 % higher profit and higher average nutrient use efficiency.

AbstractConventional agricultural practices and rising energy crisis create a question about the sustainability of the present-day food production system. Nutrient exhaustive crops can have a severe impact on native soil fertility by causing nutrient mining. In this backdrop, we conducted a comprehensive assessment of bio-priming intervention in red cabbage production considering nutrient uptake, the annual change in soil fertility, nutrient use efficiency, energy budgeting, and economic benefits for its sustainable intensification, among resource-poor farmers of Middle Gangetic Plains. The compatible microbial agents used in the study include Trichoderma harzianum, Pseudomonas fluorescens, and Bacillus subtilis. Field assays (2016–2017 and 2017–2018) of the present study revealed supplementing 75% of recommended NPK fertilizer with dual inoculation of T. harzianum and P. fluorescens increased macronutrient uptake (N, P, and K), root length, heading percentage, head diameter, head weight, and the total weight of red cabbage along with a positive annual change in soil organic carbon. Maximum positive annual change in available N and available P was recorded under 75% RDF + P. fluorescens + B. subtilis and 75% RDF + T. harzianum + B. subtilis, respectively. Bio-primed plants were also higher in terms of growth and nutrient use efficiency (agronomic efficiency, physiological efficiency, apparent recovery efficiency, partial factor productivity). Energy output (26,370 and 26,630 MJ ha−1), energy balance (13,643 and 13,903 MJ ha−1), maximum gross return (US $ 16,030 and 13,877 ha−1), and net return (US $ 15,966 and 13,813 ha−1) were considerably higher in T. harzianum, and P. fluorescens treated plants. The results suggest the significance of the bio-priming approach under existing integrated nutrient management strategies and the role of dual inoculations in producing synergistic effects on plant growth and maintaining the soil, food, and energy nexus.
