Seasonal dynamics of the brown marmorated stink bug (Halyomorpha halys [Stål]) in an urban landscape
(Taylor & Francis, 2024-09-16) Bohinc, Tanja; Batistič, Luka; Trdan, Stanislav
During the 2021–2023 period, we investigated the seasonal dynamics of the brown marmorated stink bug (Halyomorpha halys) at two locations in an urban environment in central Slovenia. We have deployed three funnel traps, in combination with aggregation pheromone at each of the locations. We have recorded daily precipitation and average temperature. The pest was monitored at three different developmental stages, i.e. adults, young nymphs and old nymphs. Based on the average daily temperature, we have calculated degree day values (DD). We found that, accounting for the lower developmental threshold of 12.2°C, overwintered adults can appear in intervals, when DD reaches already 1°C till 11°C. Young nymphs appear when the DD value ranges from 290 to 516°C. Old larvae appear at DD values from 290 to 812°C, and adults of the first generation are observed when the DD value ranges from 809 to 1054°C. Our results revealed that brown marmorated stink bugs have one generation per year in Central Slovenia, and they are present in the landscape from April to the beginning of November. The results of our research are among the first in the field of seasonal dynamics of the brown marmorated stink bug in an urban environment.
Lentil (Lens culinaris L.) cultivation in Sweden: possibilities and challenges
(Taylor & Francis, 2024-09-16) Fogelberg, Fredrik; Mårtensson, Anna M.
Swedish lentil cropping is today limited to heritage and small-scale farming. As lentils can be grown on all types of soils with standard agricultural equipment and act as a break crop in grain dominated rotations, they have come into focus for commercial production. Knowledge on cultivar choice, seeding time, possibilities for intercropping, and weed control is crucial for increased cropping. Thus, field trials combined with climate chamber experiments have investigated suitable cultivars and temperature effects on emergence. Moreover, seed rates, intercropping lentils with oats and wheat, and weed control have also been studied. Modern lentil varieties can be cropped in Sweden, typically yielding 1.5–2 MT ha−1 with a top-level yield of 3.5 to 4 MT ha−1. Intercropping with oats or spring wheat does not usually increase lentil yield. Lentil seed rates should not be less than 300 viable kernels m−2. Early seeding should be avoided as low soil temperature (8–10°C) prolongs emergence. Initial trials on suitable herbicides for Swedish conditions have shown that annual weeds are able to be controlled sufficiently. In general, there are small differences in crop performance in different fields and cultivar choice should be based on the features desired by the food industry.
Significant weed species, density and frequency in sesame cultivated areas of middle Shabelle Province in Somalia
(Taylor & Francis, 2024-09-16) Yusuf, Hussein Ahmed Nur; Alasow, Ahmed Abdiaziz; Mennan, Hüsrev
Weed competition represents a major constraint to sesame (Sesamum indicum L.) productivity, with yield losses of up to 90% reported due to uncontrolled weed infestations. However, comprehensive information on the weed flora in sesame fields is lacking, particularly in Somalia where the crop plays a vital economic and food security role. In this study, we conducted surveys across 36 sesame production areas in Middle Shabelle province, a key sesame-growing region of Somalia. Accordingly, twenty-seven weed species from 14 plant families were identified infesting the surveyed sesame fields. The results show that the most prevalent and problematic weeds in terms of density were Cynodon dactylon (2.15 plants/m2), Portulaca oleracea (1.71 plants/m2), Cyperus rotundus (1.58 plants/m2), Heliotropium steudneri (0.99 plants/m2), and Xanthium strumarium (0.87 plants/m2). The most prevalent species were Cynodon dactylon (40.70%), Xanthium strumarium (40.50%), Portulaca oleracea (37.42%), Heliotropium steudneri (35.90%), and Cyperus rotundus (26.85%). Furthermore, face-to-face interviews with 50 farmers demonstrated that most producers favour hand hoeing as the primary method for weed control. By characterising the major weed species and their population dynamics, this study provides critical foundational data to inform the development of integrated weed management strategies for enhancing sesame productivity and food security in the region.
Enhancing growth, yield and physiological quality of sweet pepper fruit through application of fertiliser and moringa leaf powder (MLP)
(Taylor & Francis, 2024-09-17) Dlamini, Siyabonga Welcome; Bertling, Isa; Ngcobo, Bonga Lewis
Most farmers rely heavily on inorganic fertilisers to enhance the production of horticultural crops. This can lead to environmental pollution, soil degradation and even human health problems. Reducing the usage of inorganic fertilisers by incorporating organic fertilisers (e.g. moringa leaf powder (MLP) and chicken litter (CL)) into inorganic fertiliser blends is likely to impact the environment less negatively than the sole application of inorganic fertiliser. The aim of this study was to produce sweet peppers using a combination of organic and inorganic fertilisers. In a controlled environment, MLP (20 g) was blended with CL (30 g) and inorganic fertiliser (Nitrogen Phosphorus and Potassium (NPK 3:1:3)) at different concentrations (10 g (33,33%), 20 g (66,66%), and 30 g (100%)), and applied to the root zone of transplanted sweet pepper seedlings. Treating sweet pepper plants with NPK (20 g) + CL (30 g) + MLP (20 g) resulted in the highest yield, with fruit containing higher total carotenoid concentrations than other treatments. Neither leaf number nor plant height was positively correlated with fruit weight per plant. Leaf chlorophyll and fruit carotenoids were present in the highest concentration in the chemical fertiliser (20 g) + CL (30 g) + MLP (20 g) (T11). Based on the yield, the best-performing combination (3:1:3 fertiliser with CL and MLP), optimal carotenoid concentration on pepper fruits was obtained on chemical fertiliser (20 g) + CL (30 g) + MLP (20 g), suggesting that peppers perform well, despite chemical fertiliser reduction from 30 to 20 g per plant, if CL and MLP are added to the medium.
Integrated analysis of agronomic traits and nutritional composition in Bambara groundnut: correlation, regression, and path coefficient approaches
(Taylor & Francis, 2024-09-17) Hlanga, Nokuthula C.; Modi, Albert T.; Mathew, Isack; Sibiya, Julia
Bambara groundnut is vital for food security due to its high nutritional content and resilience to environmental stresses. The objectives of the study were to determine associations among agronomic traits and nutrients in Bambara groundnut and identify traits influencing grain production in Bambara groundnut. Field experiments were conducted at the University of KwaZulu-Natal's Ukulinga Farm and Controlled Environment Facility (CEF) to assess agronomic performance and nutritional content. Nutritional content was evaluated using standard combustion procedures and electron microscopy. Correlation, regression, and path coefficient analyses revealed varying relationships among agronomic traits, nutrient content, and grain yield. The number of seeds (NS), healthy seeds (NHS), and plant height (PH) exhibited significant associations with grain yield. Neutral detergent fiber (NDF), starch, magnesium (Mg), nitrogen (N), oxygen (O), and phosphorus (P), were the key predictors of grain yield productivity. Path coefficient analysis showed that NS, PH and magnesium, oxygen, and carbon contents positively affected grain yield. In conclusion, grain yield was influenced by multiple traits through different pathways that are complicated by the growing environment. Selecting taller genotypes with good agronomic traits and high nutrient content is recommended to develop high yielding Bambara groundnut cultivars.
