“…According to Boyé et al (2016), the variability observed within varieties concerning the number of seeds per pod reflects their ability to mobilize assimilates to reserve structures. Concerning the weight of 100 seeds, Khan et al (2010) showed that the variability obtained between varieties depends on genotype and climatic factors. According to Khan et al (2010) a very significant variation was reported in the 24 cowpea genotypes, and in this, the climatic adaptation factor could also play a role in the increase of seed weight.…”

As a result, vegetable cowpea varieties with the highest number of seeds per pod and weight of 100 seeds could be produced as both seed cowpea and vegetable cowpea.…”

Vegetable Cowpea (Vigna unguiculata) is one of the neglected legumes in Burkina Faso, and as a result, its genetic diversity remains poorly known. The main aim of this study was to know its genetic variability through an agro-morphological characterization. Twenty vegetable cowpea varieties were evaluated at the Kamboinsé Environmental, Agricultural and Training Research Center following a three-replication Fischer block design under rainfed conditions. Fifteen quantitative and nine qualitative variables were collected and subjected to various statistical analyses. Analysis of variance was significant for the variables 50% flowering, vegetable cowpea date, number of pods obtained per plant, number of seeds per pod, fresh pod weight, fresh pod yield, pod length, plant height, seed length and chlorophyll content. Strong correlations were also reported between the various variables. The observed diversity is structured in three morphological groups viz., Group 1 consists of individuals with early flowering, high chlorophyll content and the number of pods obtained per plant. Group 2 brings together the varieties of average agronomic performance for pod length, the number of pods per plant, number of days at 95% maturity, fresh pod weight, yield of fresh pods and group 3 of varieties with long pods, early green date, high pod weight and good fresh pod yield. Among the tested varieties, the varieties IT83S-872 (30 pods), IT84S-2246 (27 pods), Baguette (25 pods), IT83S-818 (26 pods), and IT85F-2682 (24 pods) stood out for their high pod production. In addition, the varieties of vegetable cowpea baguette, baguette grimpant, Telma, and IT83S-911 showed the best performance in terms of early vegetable cowpea date stage, longest pods, highest pod weight and best yield of fresh pods. The high genetic variability level within the tested varieties could be exploited in future green cowpea breeding programmes.

“…Sugarcane staling is one of the signi cant issues of the sugar industry, and it causes signi cant economic losses because of cane and sucrose deterioration during storage and transportation (Solomon, 2009;Khan et al, 2020). The postharvest sugarcane biodegradation necessitates the abating of harvest to crush delays.…”

Background Sugarcane is an essential crop for sugar and ethanol production. Immediate processing of sugarcane is necessary after harvesting because of rapid sucrose losses and deterioration of stalks. This study was conducted to fill the knowledge gap regarding the exploration of fungal communities in harvested deteriorating sugarcane. Experiments were performed on simulating production at 30 ℃ and 40 ℃ after 0, 12, and 60 hours (h) of sugarcane harvesting and powder-processing. Results Both pH and sugar content declined significantly within 12 h. Fungal taxa were unraveled using ITS amplicon sequencing. With the increasing temperature, the diversity of the fungal community decreased over time. The fungal community structure significantly changed within 12 h of bagasse storage. Before storing, the dominant genus (species) in bagasse was Wickerhamomyces (W. anomalus). Following storage, at 30 ℃ and 40°C, Kazachstania (K. humilis) and Saccharomyces (S. cerevisiae) gradually grew, becoming abundant fungi. We found that the bagasse at different temperatures had a similar pattern after storage for the same intervals, indicating that the temperature was the primary cause for the variation of core features. Moreover, the impact of dominant fungal species on sugar content and pH of stored sugarcane juice was investigated. Also, the correlation between top fungal genera and significant environmental factors was assessed. Conclusions The study highlighted the importance of timeliness to refine sugar as soon as possible after harvesting the sugarcane crop. The lessons learned from this research are vital for sugarcane growers and the sugar industry for minimizing postharvest losses.

“…Pre-harvest burning cane exacerbates post-harvest deterioration rates and requires a short delay of the harvest-to-crush, with a burnt cane left more exposed and reaching higher deterioration levels than green cane [ 15 , 16 ]. Sugarcane staling is one of the significant issues of the sugar industry, and it causes significant economic losses because of cane and sucrose deterioration during storage and transportation [ 5 , 17 ]. The post-harvest sugarcane biodegradation necessitates the abating of harvest-to-crush delays.…”

Moreover, most of the top fungal genera were significantly correlated with environmental factors (pH and sucrose of sugarcane, storage time, and temperature). In addition, the impact of dominant fungal species isolated from the deteriorating sugarcane on sucrose content and pH in the stored sugarcane juice was verified. Conclusions The study highlighted the importance of timeliness to refine sugar as soon as possible after harvesting the sugarcane. The lessons learned from this research are vital for sugarcane growers and the sugar industry for minimizing post-harvest losses.
