The effect of such localized application increases by concentrating more nutrients near the roots; however, this also increases the risk of salt stress known as fertilizer burning. The study aimed to identify the effect and burning risk of P-dipping on the initial rice growth under a range of temperatures. Rice seedlings were dipped instantly or for 2 h in slurry with different P2O5 concentrations at 0% (P0), 2.3% (P1), and 4.4% (P2), transplanted with the slurry attached to the seedling roots, and grown for 21–28 days at the day/night temperatures of 28°/20°C, 33°/25°C, and 36°/27°C. A significant interaction effect was detected between the P2O5 concentrations and growing temperatures on shoot biomass. With the P-dipping treatments, shoot biomass was increased 4.8–5.2 times at 28°/20°C. The effect of P-dipping became less significant with increasing temperatures because of the greater rates of withered leaves soon after transplanting. Burning damage was the greatest when the P2 treatment was combined with longer dipping duration at the 36°/27°C, nullifying the effect of P-dipping on shoot biomass. The results clearly showed that localized P application is more effective under lower temperatures, with lower risk of fertilizer burning. Elevated temperatures may disturb the effort to increase rice yields with minimal fertilizer inputs via localized application.

The objectives of this study were to (i) assess the yield potentials of improved rice varieties developed by the Africa Rice Center (AfricaRice), and (ii) to allow farmers to select improved varieties of their choice based on growth and yield, as observed in the field, in order to ensure a high adoption rate, increase productivity and food security. Two seasons (i.e. 2020 major and 2020–2021 minor) field experiments were conducted at two lowland within the Mankran watershed in the Ashanti region of Ghana. The experiment comprised thirteen (13) improved varieties and two local checks and was conducted using recommended good agronomic practices. The key findings of the study showed that growth and yield parameters vary significantly between varieties across locations. The biplot analysis showed that varieties FARO 66, SAHEL 317, and Amankwatia are the best in the major season while WITA 9, GT 11, ARS-957-BGJ-171-15-D-B, NERICA L36, and AGRA were the best in the minor season at both locations. Farmers’ preference for the varieties was based not only on growth and yield but on resistance to lodging, pests, and diseases. In conclusion, the best performing varieties have demonstrated yield potential which is about 92% higher than the yield of the local checks and can be recommended for adoption by farmers. Future breeding programs on these varieties should include the most preferred attributes by farmers in this study.

QTLs for tolerance to high temperature during ripening must be identified in order to develop new cultivars efficiently. Here, we developed recombinant inbred lines (RILs) from crosses between the high-temperature-tolerant ‘Genkitsukushi’ and the high-temperature-sensitive ‘Tsukushiroman’. The occurrence of white-back grains is significantly lower in ‘Genkitsukushi’ than in ‘Tsukushiroman’. We evaluated their high-temperature tolerance and performed quantitative trait locus (QTL) analysis. A QTL for white-back grains on chromosome (chr.) 6 and a large-effect QTL on chr. 8 were identified in the two-year experiments. The QTL on chr. 8 was close to one we previously detected using RILs derived from ‘Chikushi 52’ × ‘Tsukushiroman’. The results indicate that the QTL on chr. 6 is unique to ‘Genkitsukushi’ × ‘Tsukushiroman’, and that on chr. 8 could be identical between ‘Genkitsukushi’ and ‘Chikushi 52’. Backcrossed lines which harbor the QTL region on chr. 8 of ‘Genkitsukushi’ in the background of ‘Tsukushiroman’ verified its effects. We also analyzed the marker genotypes near the QTLs on chr. 6 and 8 in relatives of ‘Genkitsukushi’. We discuss the interaction between these QTLs and their relationship with high-temperature tolerance.

Bacterial wilt caused by Ralstonia solanacearum (RS) and bacterial spot caused by Xanthomonas axonopodis pv vesicatoria (Xav) are amongst the bacterial diseases affecting tomato crops. The current study investigates Euphorbia hirta (E. hirta) methanol extract (EHM) for its antibacterial activity against RS, and Xav induced diseases in tomato plants, along with its biostimulant potential in increasing fruit yield. EHM at 1280 mg/L exhibited 90% inhibition in the growth of both RS and Xav bacteria. Further, evaluation of EHM on Arka Vikas, a susceptible tomato variety, showed that pre-treatment of 15 days and 45 days tomato plants with 1280 mg/L EHM exhibited moderate resistance to bacterial wilt and spot disease, respectively, with increased tomato yield and improved chlorophyll b levels compared to control plants. The effectiveness of EHM in increasing fruit yield was further confirmed using field evaluation on ‘Namdhari NS 538’ variety of tomato plants. A 3.5-fold increase in numbers and weight of tomato was observed with foliar application of EHM (1280 mg/L). A significant reduction in fruit spoilage along with an increase in mRNA level of ethylene receptor factor (ERF1) was also observed. The study is the first to demonstrate the cost-effective and eco-friendly antibacterial and biostimulant potential of EHM (1280 mg/L) for tomato plants.

The treatment also significantly increases the yield components of the red variety of djulis, such as spike length and thousand-grain weight. Treating the red variety of djulis with calcium carbonate in spring significantly increased the antioxidant enzyme activity such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR) activities. Interestingly, results indicated that calcium carbonate treatment could promote the early maturation of the mid-late-maturing red variety of djulis and delay the maturation of the early-maturing yellow variety.

IR64-NIL12 carrying qTSN12.2-YP4, which was detected on chromosome 12 for TSN per panicle, has been developed in a previous study. It is important to characterize the environment of gene function to increase yields. Thus, we attempted to evaluate IR64-NIL12 grown under no, low, and high fertilizer conditions in 2019 and 2020. Grain yields of IR64-NIL12 were significantly higher than that of IR64 in all conditions. The average grain yield of each condition for IR64 and IR64-NIL12 ranged from 387 to 616 g m−2. Therefore, qTSN12.2-YP4 would have an increasing effect on grain yield within this range. The ratio of fertility improved in IR64-NIL12. This rice line exhibited modified traits, such as tiller number and plant height (during the vegetative stage), as well as panicle number (at maturity), which may confer an advantage in terms of light-intercepting characteristics. We also focused on the number of unproductive tillers and dry weight per tiller at the heading stage to investigate the mechanism of the increasing effect of qTSN12.2-YP4 on TSN per panicle. There is a significant difference in dry weight per tiller at heading between IR64 and IR64-NIL12, but not in the percentage of unproductive tillers. Therefore, this result indicated that qTSN12.2-YP4 contributes to increasing dry weight per tiller until the heading stage and, consequently, TSN per panicle.

However, information on the performance of coffee genotypes in various environmental conditions is limited. Thus, this study’s objectives were to estimate genotype by environment interaction (GEI), evaluate the mean performance and stability of 16 fruity flavored coffee genotypes in eight specialty coffee growing environments in western Ethiopia, and assess the magnitude of correlations among different stability parameters. The experiment was laid out in a randomized complete block design (RCBD) with two replications. For coffee yield, data were recorded and a combined analysis of variance and stability analysis were performed. Additive main effect and multiplicative interaction (AMMI) analysis revealed that genotypes, environments, and GEI showed highly significant differences (P < .0.01) for coffee bean yield. AMMI analysis also revealed that 73.2% of the GEI sum of squares for coffee bean yield was accounted for by the first three interaction principal component axes (IPCA). The standard check variety G16 (Menesibu), G3(W54/99), and G10 (W107/99) gave the highest average yields of 1537, 1458 and 1375 kg of clean coffee per hectare across environments, respectively. Despite no genotypes consistently performing well across environments due to the high GEI, G1 (W13/99) and G5 (W54/99) were relatively stable. Therefore, these were recommended as useful genetic resources for breeding of high-yielding genotypes. However, since all the genotypes gave a mean yield below the standard check variety, additional genotypes should be tested in more environments to develop stable and high-yielding coffee varieties.
