Effect of organic and bio fertilization and magnesium foliar application on soybean production

Abstract

GYPT has paid great attention to expanding the cultivation of oil crops such as soybean by developing plans and strategies, including the research plans, which were developed by the Agricultural Research Center. These plans aim to increase the areas cultivated with oil crops and simultaneously raise the productivity of the cultivated unit. To improve soybean production, a field experiment was carried out in a split-plot design for two successive years (2021 and 2022 ) where the six treatments of organic and bio fertilization were found in the main plots [T 1 : Control (without), T 2 : Rhizobium inoculation (RH) , T 3 : Farmyard manure FYM at rate of 36.0 m 3 ha -1 , T 4 : Plant compost PC (sugar cane and banana residues at ratio of 50:50) at rate of 36.0 m 3 ha -1 , T 5 : T 2 + T 3 (RH+ FYM) and T 6 : T 2 + T 4 (RH+ PC)]. The sub-main plots were assigned for foliar application of magnesium (Mg) [F 1 : Control (without foliar application) and F 2 : Mg sprayed at rate of 1440 g ha -1 using magnesium sulphate (MgSO 4 , consisting of 20.19 Mg % by mass)].The main results showed that the superior treatment for obtaining the maximum values of growth performance e.g., plant height (87.16 and 88.12 cm, for 1 st and 2 nd seasons, respectively), dry weight(14.99 and 15.18g, for 1 st and 2 nd seasons, respectively)and chlorophyll(46.22 and 47.41 SPAD, for 1 st and 2 nd seasons, respectively) wasthe T 6 treatment (combination of RH and PC) followed by T 5 treatment (combination of RH and FYM) then T 4 , T 3 , T 2 and T 1 , respectively. The same trend was found also for all parameters which expressed quantitative and qualitative yield of soybean e.g.,number of pods plant -1 , seed yields, oil, protein and carbohydrates in seeds, where the T 6 treatment came in the first order, while theT 1 treatment came in the last order. Regarding the Mg treatments, the plant growth performance, quantitative and qualitative yield significantly increased with Mg foliar application (F 2 )compared to the corresponding soybean plants grown without Mg addition(F 1 ). Generally, it can be concluded that the combined treatment (rhizobium inoculant + plant compost+ magnesium) will achieve the highest plant growth performance, quantitative and qualitative yield of soybean. Thus, can meet people's needs for strategic oil crops.

Effects of Various Organic Fertilizer Sources and External Applications of Potassium Fulvate and Potassium Citrate on the Yield and Quality of Two Barley Varieties Grown under Salt Affected Soil

“…Enhanced photosynthetic pigments are crucial for maintaining plant growth and productivity under stress (Jamshidi and Javanmard, 2018). The superior performance of compost in enhancing photosynthetic pigments and leaf nutrient content aligns with its high nutrient availability and soil conditioning properties, which improve overall plant health and nutrient uptake(El-Sherpiny and Faiyad, 2023; Elsherpiny et al 2023). Potassium fulvate's role in enhancing photosynthetic pigments and nutrient content can be linked to its ability to improve nutrient solubility and uptake, thus supporting better plant metabolic functions.…”

“…Compost, derived from the aerobic decomposition of organic waste, is an excellent soil conditioner that supplies a balanced mix of macro-and micronutrients, enhances soil microbial activity, and improves soil structure. Chicken manure (ChM) is particularly high in nitrogen, phosphorus, and potassium, making it a potent fertilizer that boosts plant growth and productivity (El-Sherpiny and Faiyad, 2023;Elsherpiny et al 2023).…”

Enhancing Soybean Productivity in Saline Soil Conditions: Synergistic Effects of Organic Fertilizer and Proline Co-Application

“…As a versatile legume, soybeans contribute substantially to global protein and oil production, playing a crucial role in human and livestock nutrition. Understanding and enhancing soybean performance under saline conditions is thus not only imperative for global food security (Elsherpiny et al 2023). Considering these considerations, the overarching goal of this experiment is to provide a comprehensive understanding of the interplay between organic fertilization, proline amino acid application, and soybean cultivation in saline soils.…”

Wheat Productivity as Influenced by Integrated Mineral, Organic and Biofertilization

“…Following a circular economy might be an excellent choice via recycling agricultural products in soil (Diacono et al 2019). Many organics can be used to attain these aims such as manure (Cai et al 2019), compost (Elshony et al 2019;Hussein et al 2022; Elsherpiny 2023; Elsherpiny et al 2023;Nada et al 2023; Sarhan and Shehata 2023), biochar ____________________________ Egypt.
