Among the various disposal strategies for sewage sludge (SS), soil application is the most suitable. This study was conducted to evaluate soil amendment with SS (0, 10, 20, 30 and 40 g/kg) and its impact on soil fertility and tomato (Solanum lycopersicum L.) growth. The SS significantly improved the agromorphological attributes, the number of produced fruits, and the fruit biomass of tomato plants. The 30 g/kg application of SS led to the highest growth rate and fruit yield. Considering the fruits, the best safe enrichment of metal nutrients was recorded at 30 g/kg, with a significant increase in the micronutrient metals Mn, Zn, Ni, Cu, and Fe with 624, 193, 125, 70, and 32%, respectively, compared to the control. The SS amendment enhanced soil fertility, and heavy metals were within the permissible ranges for agricultural soils. Bioaccumulation factors (BFs) indicated that SS application induced the accumulation of most of the studied metals in the roots, and the BF values of Zn, Cu, Ni, and Pb were > 1. The current study concluded that recirculating SS nutrient components to agricultural soils could offer a valid solution for the sustainable management of this organic waste and enhance plant-crop productivity.

In Sudan's agro-ecological zone, tomato production is constrained by a dearth of high fruit yielding and quality (Solanum lycopersicum [L.]) varieties for cultivation in polyhouse. Exotic and indeterminate tomato genotypes with high fruit yield and quality were evaluated to gain information on variation for fruit yield, quality, shape, and interdependence between traits in Sudan agroecology. The seed was sown during 2018 and 2019. Fruit yield, quality, and phenomic traits were measured. Development, °Brix, and fruit yield responded to microclimate factors in the polyhouse over years. ‘Bruno’ was the best for fruit size and ‘Tofi’ for fruit number. Vine length at flowering, fruits/cluster, days to 50% flowering, and days to first flowering and fruit brix are heritable. The genotype responses suggest the need for stable and to develop high-yielding and quality tomato varieties for protected cultivation in the Sudan agro-ecological zone. Testing stable genotypes in locations could enhance breeding efficiency with respect to genotypic stability. The yield data gained under tropical conditions identified traits of superior genotypes for multiple environment studies and to encourage tomato growers to consider protected cultivation in the tropics.

Antioxidant Mechanisms

Given the widespread use of glyphosate (GLY), this agrochemical is becoming a source of contamination in agricultural soils, affecting non-target plants. Therefore, sustainable strategies to increase crop tolerance to GLY are needed. From this perspective and recalling silicon (Si)’s role in alleviating different abiotic stresses, the main goal of this study was to assess if the foliar application of Si, either as bulk or nano forms, is capable of enhancing Solanum lycopersicum L. tolerance to GLY (10 mg kg−1). After 28 d, GLY-treated plants exhibited growth-related disorders in both shoots and roots, accompanied by an overproduction of superoxide anion (O2•−) and malondialdehyde (MDA) in shoots. Although plants solely exposed to GLY have activated non-enzymatic antioxidant mechanisms (proline, ascorbate and glutathione), a generalized inhibition of the antioxidant enzymes was found, suggesting the occurrence of great redox disturbances. In response to Si or nano-SiO2 co-application, most of GLY phytotoxic effects on growth were prevented, accompanied with a better ROS removal, especially by an upregulation of the main antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX). Overall, results pointed towards the potential of both sources of Si to reduce GLY-induced oxidative stress, without major differences between their efficacy.

Pruning Methods

Tomato is one of the most widely consumed and produced vegetables in Ghana. The low yield of tomatoes in Ghana has resulted in huge importation of the produce from neighboring countries. Good agronomic practices are among the key strategies involved in increasing the yield of horticultural produce. This study seeks to evaluate the response of staking and pruning on tomato fruit yield, quality, and cost of production. To achieve this, a field experiment was conducted to investigate the effect of staking and pruning methods on fruit yield and profitability of tomato (Solanum lycopersicum L.) produced in the northern region of Ghana. Treatments were applied in a randomized complete block design with three replications. Treatments were no pruning + no staking (control), single pole staking (SPS), wire trellis (WT), one-stem pruning (1SP), one-stem pruning + single pole staking (1SP + SPS), one-stem pruning + wire trellis (1SP + WT), two-stem pruning (2SP), two-stem pruning + single pole staking (2SP + SPS), and two-stem pruning + wire trellis (2SP + WT). Results showed that 2SP + WT increased fruit diameter, fruit length, and marketable fruit weight by 52%, 32%, and 69%, respectively, compared to the control. The maximum number and weight of marketable fruits obtained from 2SP + WT increased total fruit yield by 76% compared to the control. In all, the performance of the treatments in terms of yield was in the following order: 2SP + WT > 1SP + WT > SPS > WT > 2SP + SPS > 1SP > 2SP > control. Though 2SP + WT increased production cost by 42%, it greatly increased yield by 69% which resulted in 83% net profit compared to the control. Thus, 2SP + WT could be tested on-farm for possible adoption to increase tomato yield, quality, and profit.

AbstractPhelipanche aegyptiaca is an obligate holo-parasitic weed lacking a functional photosynthetic system, which subsists on roots of a wide range of host crops, causing severe losses in yield quality and quantity. The parasite and its host are connected through their vascular system, forming a unique ecological system that enables the exchange of various substances. In a previous study, it was suggested that endophytic bacteria, which naturally inhabit the internal tissues of plants, can also be transmitted from the parasitic weed to its host and vice versa.In the current study, we investigate the characteristics of a previously isolated Pseudomonas sp. PhelS10 strain, using both biochemical and molecular methods. Our results revealed that production of Pseudomonas aeruginosa quinolone signal (PQS) was 2.1 times higher than that of the standard Pseudomonas aeruginosa strain (PAO1), which contributed to a 22% higher biofilm formation capability. PhelS10 strain was detected in the xylem of tomato plants using FISH analysis. In addition, PhelS10 strain was found in the parasitic weed’s inner tissues, confirming the hypothesis that endophytic bacteria traffic between the plant host and its parasitic weed.

A Pseudomonas sp. 102 strain, which is highly resistant to toxic effects of cadmium and has plant growth-promoting activity, can significantly increase growth parameters and biomass of tomato plants, including those observed under toxic effects of cadmium. The greatest positive effect was observed in plants transformed with the bacterial adhesin gene rapA1, the product of which is important for colonization of plant roots by bacteria. It was also shown that shoots of transgenic tomato plants accumulated the greatest amount of cadmium during inoculation with Pseudomonas sp. 102. The ability to extract high concentrations of cadmium and accumulate a large biomass under stress opens up prospects for the further use of associative interactions between tomato and Pseudomonas for phytoremediation. phytoremediation, cadmium, tomato, Pseudomonas, inoculation, agglutinins, This study was carried out using the equipment of the Biomika Centre for Collective Use of the Institute of Biochemistry and Genetics (Ufa Federal Research Centre, Russian Academy of Sciences) as part of the government task (project no.
