“…Results showed that the use of a mixture of PG and BC improved the soil's hydrophysical and chemical properties, resulting in less evapotranspiration losses, making water available for crops for a longer period which protecting the crop against water stress and consequently, increasing WUE and WP. Our results concur with (Faloye et al, 2020, Bossolani et al, 2021 andZahra et al, 2021). Studies show that BC has a high porosity and surface area which leading to an increase in the general soil porosity and water content, reducing water stress for plants (Batista et al, 2018).…”

Egypt has a severe water shortage, made worse in recent years by the building of the Renaissance Dam. Thus, the purpose of this research is to assess the role of soil amendments in mitigating the negative influences of water stress and improving maize productivity. A field experiment was carried out at El-Gemmieza Agriculture Research Station, El-Gharbia Governorate, during the two successive summer seasons of 2021 and 2022 to study the influence of three levels of available soil moisture depletion (AVSMD) and soil amendments biochar (BC) and phosphogypsum (PG) on soil physical proprieties, some physiological traits and maize productivity (TWC 368). The experiment was laid out in a split-plot design with four replicates. The main plots were occupied by three levels of (AVSMD) irrigation at 50 % of AVSMD,I1(moist);irrigation at 65 % of AVSMD,I2 (medium) and irrigation at 80 % of AVSMD, I3 (dry). Whereas subplots contained six treatments of BC and PG singly or in combination, i.e., (T1: control, T2: 2 ton BC fad -1 , T3: 4 ton BC fad -1 , T4: 2 ton PG fad -1 , T5: 4 ton PG fad -1 and T6: 2 ton BC fad -1 plus 2 ton PG fad -1 ).The results indicated that, increasing soil moisture stress up to (I3) significantly decreased total porosity (Tp), soil hydraulic conductivity (Hc), organic matter (OM), available N, P, K, chlorophyll a (chl. a), b, shoot dry weight, leaf area (LA), leaf relative water content (LRWC),days to 50 % silking, plant height, antioxidant enzymes, ear length, 100-kernel weigh and grain yield, Whereas, bulk density (Bd),soil pH, chl. a/b ratio, proline and water measurements significantly increased in both seasons. Application (T6) significantly increased all mentioned traits except Bd, pH, chl. a/b ratio, proline, water applied (WA) and water consumptive use (WCU). From the interaction between water stress treatments and soil amendments addition, It can be summarized that irrigation of maize plants at I1 or I2 with T6 improved pH, OM, available P and K, as well as achieved the highest values for chl. a, LA, LRWC, days to 50% silking, plant height, ear length, 100-kernel weight, grain yield, as well as improved water use efficiency (WUE) and water productivity (WP). While applying (I2) with (T6) recorded the highest values of Hc and antioxidant enzymes.

“…Nevertheless, the levels of available phosphorus and exchangeable calcium were relatively low. Mosharrof et al [33] observed that the choice of raw materials and the pyrolysis temperatures utilized in biochar production had an impact on the ash content. The high nutrient requirement, as maize in known to be a heavy feeder crop or high nutrient uptake of maize from the soil for growth and development might have led to a substantial reduction in soil nutrients at both trial locations after harvesting.…”

Aims: Maize yield is largely influenced by integrated nutrient management of biochar, organic and inorganic fertilizers application. In view of this, field study to evaluate varying rates of chicken manure (CM), Gliricidia sepium biochar (GB) and NPK fertiliser on growth and yield of maize was carried out. Study Design: The study design was a 2 x 6 factorial arranged in Randomized Complete Block Design with three replications. Place and Duration of Study: The field study was carried out at Mampong- Ashanti in the Forest-Savannah transition zone of Ghana over 2 years in 2021 minor and 2022 major cropping seasons. Methodology: The study treatments were different rates of amendments using biochar, chicken manure and NPK (15-15-15) fertiliser; [10 t ha-1 CM, 300 kg ha-1 NPK, 2.5 t ha-1 GB, 150 kg ha-1 NPK + 1.25 t ha-1 GB, 1.25 t ha-1 GB + 5 t ha-1 CM and No fertiliser (Control)] which were applied to two maize varieties (Omankwa and Obatanpa). Physiological growth parameters (crop growth rate and relative growth rate) were determined. Vegetative growth parameter (leaf count) as well as yield and yield traits (number of lodged plants per plot, husked cob weight per plot, number of filled and unfilled cobs per plot and grain yield) were estimated. Results: The results revealed that the application of 10 t ha-1 chicken manure and 1.25 t ha-1 GB + 5 t ha-1 CM to Omankwa and Obatanpa maize outperformed in crop growth rate (RGR), relative growth rate (RGR) and leaf count compared to the unamended plots in both seasons. Omankwa had significantly higher filled cobs per plot than Obatanpa across seasons. The interaction of Omankwa and 10 t ha-1 CM and 1.25 t ha-1 GB + 5 t ha-1 CM gave higher number of filled cobs per plot than Obatanpa on same although not significantly different in both cropping seasons. The grain yield of maize was enhanced by soil amendments in the major and minor cropping seasons, especially with interaction of Obatanpa and 10 t ha-1 CM (7474.0 kg ha-1), (3473.4 kg ha-1) respectively. Obatanpa x 1.25 t ha-1 GB + 5 t ha-1 CM (6802.1 kg ha-1) interaction followed closely in grain yield in the major season. Conclusion: Both biochar, organic and inorganic fertilizers have varying effects on growth and yield of different maize varieties. For optimize maize grain yield, 10 t ha-1 CM or 1.25 t ha-1 GB + 5 t ha-1 CM application is recommended.

“…Moreover, earlier findings also showed increased grain yield with increased levels of biochar and its quality [10,33,47]. Similarly, Mehnaz et al [48] concluded increased maize yield in combined application of biochar and mineral fertilizer compared with only applying mineral fertilizer or biochar in their review.…”

Mixed application of organic and inorganic fertilizers in mixture improves soil fertility and crop productivity. However, the identification of combined application level is important. Therefore, a field experiment was conducted in 2020 in the Guto Gida district to assess the effect of maize cob biochar levels and inorganic NPS fertilizer rates on the growth and yield of maize. The study was conducted in factorial combinations of five rates of maize cob biochar and three rates of inorganic NPS fertilizer using a randomized complete block design with three replications. The main effect of the biochar level and NPS rate significantly affected crop phenology and biomass yield, whereas the number of kernels ear−1 was affected by the main effect of NPS rate. The combined application of biochar and NPS fertilizer significantly influenced plant height, leaf area index, ear weight, thousand kernel weight, grain yield, and percentage of grain yield. The interaction of biochar at 8 t·ha−1 with 100 kg·ha−1 NPS resulted in highest leaf area index (5.56), grain yield (7.03 t·ha−1), and yield increment (18.11%) followed by 8 t·ha−1 × 50 kg·ha−1 and all biochar levels with 100 kg·ha−1 NPS. In addition, the highest values of ear weight (276 g) and thousand kernel weight (47.81 g) were recorded in plots treated with combined application of biochar and NPS fertilizer at rates of 8 t·ha−1 × 50 kg·ha−1 and 4 t·ha−1 × 100 kg·ha−1, respectively, whereas plots not treated with both biochar and NPS resulted in lowest yield followed by 0 t·ha−1 × 50 kg·ha−1. In conclusion, integrated application of maize cob biochar at 8 t·ha−1 with NPS fertilizer at 50 kg·ha−1 improved the yield of maize by about 16.85% with net benefit of 61700.50 ETB ha−1 and marginal rate of return 733.68%, and therefore, the application of biochar at this rate with mineral NPS fertilizer at 50 kg·ha−1 is considered as suitable for the study area.
