Because of its potential for large-scale production, soybean (Glycine max (L.) Merrill) has ex‐ celled in the world agricultural economy as a major oilseed crop. At present, soybeans are grown primarily for oil extraction and for use as a high protein meal for animal feed (Singh & Shivakumar, 2010). According to Li-Juan & Ru-Zhen (2010), soybean has a protein content of approximately 40% and an oil content of approximately 20%. In 2010, the area planted with soybeans worldwide was 102.4 million…

Physiological Response of Soybean [Glycine max L. Merril] Genotypes to Drought-induced Stress: Preliminary Screening for Drought under South Sudan Agro-ecological (Ironstone/Mountains) Conditions

The result showed that drought stress is an important factor in growth and yield reduction especially when drought stress occur at reproductive stages such as initial pod filing, beginning of seed formation and full seed stages is responsible for yield reduction compared to non drought stress conditions.

Morphological and Physiological Performance of Indian Soybean [Glycine max (L.) Merrill] Genotypes in Respect to Drought 

It can be concluded that drought stress retards the growth and metabolic activity of soybean genotypes and showed considerable amount of variability under drought stress at different growth stages in soybean.

EVALUATING THE EFFECTS OF BIOCHAR AMENDMENTS ON DROUGHT TOLERANCE OF SOYBEAN (GLYCINE MAX L.) USING RELATIVE GROWTH INDICATORS

Drought is the extremely critical environmental limitation that restricts crucially the leaf growth, stem elongation and overall plant growth rate. In the agricultural lands biochar has its

Root growth and crop performance of soybean under chemical, physical, and biological changes after subsoiling

Chemical, physical and biological soil attributes can facilitate soybean root growth in greater volume and depth in the soil, which can minimize yield reduction caused by water deficit. Soil

Soy is a crop of great expressiveness worldwide and Brazil is currently the largest producer and exporter of this crop, with territorial potential for expansion of its cultivation. In view of the

Effect of growth regulators and sowing date on the agronomic performance of corn hybrids in the first cropping year Reguladores de crescimento e épocas de semeadura no desempenho agronômico de híbridos de milho na primeira safra

Growth regulators can be an important tool in corn crop management, especially in technology-intensive crops grown in densified spatial arrangements, under favorable environmental conditions, and

Neonicotinoid insecticide systemicity in soybean plants and its effect on brown stink bugs

Evaluating the systemicity of thiamethoxam insecticide in different soybean phenological stages, using brown stink bugs as bioindicators of the pesticide efficacy found that in all stages, stink bugs were satisfactorily controlled.

Comprehensive Genomic Analysis and Expression Profiling of Diacylglycerol Kinase (DGK) Gene Family in Soybean (Glycine max) under Abiotic Stresses

This work provides the first characterization of the DGK gene family in soy bean and suggests their importance in soybean response to abiotic stress.

Soybean Nodule Size and Relationship to Nitrogen Fixation Response to Water Deficit

Drought tolerance of Jackson is partially due to the advantages of large nodules, but that drought tolerance in Jackson also results from an inherently greater supply of photosynthates to nodules.

Physiological and molecular approaches to improve drought resistance in soybean.

The objective of this review is to consolidate the current knowledge of physiology, molecular breeding and functional genomics which may be influential in integrating breeding and genetic engineering approaches for drought resistance in soybean.

Soybean Cultivar Differences in Ureides and the Relationship to Drought Tolerant Nitrogen Fixation and Manganese Nutrition

It is concluded that Ureides inhibit N 2 fixation, that genetic variation in the ability to degrade ureides may be important in drought tolerance, and that increased leaf Mn +2 concentration promotes ureide breakdown and prolongs N2 fixation under water deficit.

Modeling the water use efficiency of soybean and maize plants under environmental stresses: application of a synthetic model of photosynthesis-transpiration based on stomatal behavior.

The physiological explanation for differences of the relative contributions of stomata- and mesophyll processes to control of Am and WUE, and the applicability of WUE model between the two species are made clear.

Soybean N2 fixation estimates, ureide concentration, and yield responses to drought

It is indicated that the RAU technique for estimating N2 fixation under drought conditions may be invalid without further refinement, that N2fixation is more sensitive to drought than the uptake and assimilation of inorganic soil N, and that increasing the tolerance of N1 fixation to drought would likely result in yield increases.

Role of Mineral Nutrition in Alleviation of Drought Stress in Plants

An overview of some macronutrients (nitrogen, phosphorus, potassium, calcium and magnesium), micronut nutrients (Zinc, Boron, Copper and silicon) and silicon has been discussed in detail as how these nutrients play their role in decreasing the adverse effects of drought in crop plant.

Tolerance to water deficiency between two soybean cultivars: transgenic versus conventional

The results showed that both cultivars had similar effects, caused by water deficiency, on dry mass production, but the transgenic cultivar tended to maintain higher biomass allocation in pods, as well as, higher efficiency of leaves to support dry massProduction than conventional cultivar in both water conditions.
