“…Hill (hereinafter cycad) to represent gymnosperms, to investigate how incident light throughout a leaf’s construction and maturation influenced leaf physiology during the light-fleck experimental methods. Maize and soybean were selected because of their prominent position as leading crops of the world [ 11 , 12 ]. Cycas micronesica was selected because the gas exchange physiology of this species has been studied more so than other cycads [ 13 , 14 ].…”

Methods in sunfleck research commonly employ the use of experimental leaves which were constructed in homogeneous light. These experimental organs may behave unnaturally when they are challenged with fluctuating light. Photosynthetic responses to heterogeneous light and leaf macronutrient relations were determined for Cycas micronesica, Glycine max, and Zea mays leaves that were grown in homogeneous shade, heterogeneous shade, or full sun. The speed of priming where one light fleck increased the photosynthesis during a subsequent light fleck was greatest for the leaves grown in heterogeneous shade. The rate of induction and the ultimate steady-state photosynthesis were greater for the leaves that were grown in heterogeneous shade versus the leaves grown in homogeneous shade. The leaf mass per area, macronutrient concentration, and macronutrient stoichiometry were also influenced by the shade treatments. The amplitude and direction in which the three developmental light treatments influenced the response variables were not universal among the three model species. The results indicate that the historical practice of using experimental leaves which were constructed under homogeneous light to study leaf responses to fluctuating light may produce artifacts that generate dubious interpretations.

Valorization of Okara by Enzymatic Production of Anti-Fungal Compounds for Plant Protection

et al. 2021

Okara is a soybean transformation agri-food by-product, the massive production of which currently poses severe disposal issues. However, its composition is rich in seed storage proteins, which, once extracted, can represent an interesting source of bioactive peptides. Antimicrobial and antifungal proteins and peptides have been described in plant seeds; thus, okara is a valuable source of compounds, exploitable for integrated pest management. The aim of this work is to describe a rapid and economic procedure to isolate proteins from okara, and to produce an enzymatic proteolyzed product, active against fungal plant pathogens. The procedure allowed the isolation and recovery of about 30% of okara total proteins. Several proteolytic enzymes were screened to identify the proper procedure to produce antifungal compounds. Antifungal activity of the protein digested for 24 h with pancreatin against Fusarium and R. solani mycelial growth and Pseudomonas spp was assessed. A dose-response inhibitory activity was established against fungi belonging to the Fusarium genus. The exploitation of okara to produce antifungal bioactive peptides has the potential to turn this by-product into a paradigmatic example of circular economy, since a field-derived food waste is transformed into a source of valuable compounds to be used in field crops protection.

“…is one of the most important and widely grown legume crops worldwide due to its multipurpose use particularly in the animal feed industries and human nutrition. Its high quality protein and balanced amino acid profile in ration formulation and human diets are the driving forces of soybean production (Shea et al, 2020). The global average production of soybean reached 334.89 million tons per annum.…”

Soybean is a miracle legume crop in the world due to its multipurpose use. The global demand of the crop is increasing rapidly because of its growing demand particularly in the animal feed industries. But, the current production status of the commodity is not comparable to the rapidly increasing demands. The main objective of this study was to evaluate the performance of improved soybean varieties under smallholder farmers' condition in western Ethiopia. Six kebeles were selected purposively in Pawe and Jawe districts based on their potential and suitability for soybean production. A total of 24 hosted farmers were selected purposively by considering their willingness and performance to implement the demonstration. Pawe-1, Pawe-2, Pawe-3 and Ethio-Yugoslavia varieties were the materials used in the evaluation. Grain yield, seed size, pod number per plant, seed number per pod, plant height, disease resistant and maturity date were the main preference traits for farmers. Bothe qualitative and quantitative data were collected from 41 farmers (17 control group). The collected data were analyzed through descriptive and inferential statistics by using SPSS software package. Farmers' preference ranking also conducted based of their selection criteria. The combined results over locations show that 1767.58, 1723.46, 1619.58 and 1600.08 kg ha -1 mean grain yield recorded from Pawe-3, Ethio-Yugoslavia, Pawe-1 and Pawe-2 varieties respectively. Overall mean grain yield of improved varieties was 1677.68 kg ha -1 . The least (927.41 kg ha -1 ) mean grain yield observed from the local variety. Findings revealed that all the demonstrated improved varieties have significant yield advantage over the control at (p<0.01) in all locations. Farmers put Pawe-3 variety in the first rank based on the total score of their preference traits. Agricultural professionals and other concerned bodies have to give more emphasis to promote the newly released proven soybean varieties with full recommended packages to increase the production status further to ensure the demands of domestic processing and export marketing and this will contribute to the overall economic growth.
