Optimizing Growth, Seed Yield and Quality of Soybean (Glycine max L.) Plant Using Growth Substances

Abstract

Aims: It is become necessary to reduce the gap between the demand and supply of edible oil and protein. So, the aim of the present investigation is to study the effect of foliar application with humic acid, salicylic acid and paclobutrazol on some morphological, anatomical and seed yield characteristics, as well as on some biochemical constituents of soybean (Glycine max L.) seed for maximizing its growth, yield and nutritional value. Methodology: A 2 year field trial was carried out during 2015 and 2016 at the Faculty of Agriculture Experiment Station, Benha University, Egypt. Soybean (Glycine max L.) cv. Giza 111 seeds were sown into plots (each plot unit about 3.5 m long and 3.0 m wide) in clay loam soil. A total of six treatments of humic acid, salyclic acid, and paclobutrazol were foliarly applied: humic acid at 2.5 and 5.0 gl-1 , salicylic acid at 50 and 100 mgl-1 , paclobutrazol at 10 and 20 mgl-1 and Control in a 3 randomized complete blocks. Results: All rates of humic acid, salicylic acid and paclobutrazol had a significant effect on soybean morphological characters during the 2 years. The treatment set of 10 mgl-1 paclobutrazol, 5 gl-1 humic acid, and 100 mgl-1 salicylic acid resulted in relatively higher means for most vegetative Original Research Article

Effect of nanoparticle on growth, biochemical and anatomical characteristics of moringa plant (Moringa oleifera L.) under salinity stress condition

“…In general, the stimulatory effects of applied treatments upon the anatomy features of treated plants could be attributed to the effect upon cambium activity. Increment of cambium activity could mainly attributed to the increase of endogenous hormones level especially cytokinins and auxins (Abd El-Aal and Eid, 2017;Sotiropoulos et al, 2002). Generally, the obtained results clearly indicate that different applied nutrient nanoparticle treatments play a defensive protective role against adverse effects of highest salinity stress level via its regulatory functions.…”

“…The significant reduction of salinity damage and stress tolerance resulting from the addition of humic acids to the plant leads to improve the vegetative growth characters 49 sby enhancing the absorption of important nutrients, and increasing their transfer and then their accumulation in the shoot system in a significant way, such as macronutrients N, P, K, Ca, Mg, S, and micronutrients such as Fe, Zn, Mn and Cus 50 , As well as reducing the accumulation of some toxic elements by reducing their uptake, such as Na 51, 52 , as well as elongating root cells, increasing oxygen uptake and respiration, and increasing chlorophyll pigments and thus the efficiency of photosynthesis, which leads to plant tolerance to high concentrations of salinity 53,54 .…”

Improving crop yield potential: Underlying biological processes and future prospects

“…Seed filling therefore is highly important for plant fitness and is essential for food security, because it determines both seed size and nutritional quality. In crops, efficient seed filling is a key factor controlling yield (El-Zeadani et al, 2014;Houshmand et al, 2022;Reynolds et al, 2021;Sehgal et al, 2018). Several crucial steps in N allocation need to be taken into consideration to improve crop productivity and nutritional quality of harvested products (Paul et al, 2017).…”
