“…Optimal accumulation and distribution of crop dry matter play a pivotal role in achieving highquality and high-yield yam production. The combined application of organic and chemical fertilizers proves advantageous for optimizing water and nutrient conditions, promoting overall dry matter accumulation throughout the crop's growth cycle, as well as facilitating dry matter translocation to the stems [28,29].…”

This field experiment aimed to investigate the effects of different ratios of organic and inorganic fertilizers with maintaining equal nitrogen application rates on the yield, quality, and nitrogen uptake efficiency of Dioscorea polystachya (yam). Six treatments were set, including a control without fertilizer (CK), sole application of chemical fertilizer (CF), sole application of organic fertilizer (OM), 25% organic fertilizer + 75% chemical fertilizer (25%OM + 75%CF), 50% organic fertilizer + 50% chemical fertilizer (50%OM + 50%CF), and 75% organic fertilizer + 25% chemical fertilizer (75%OM + 25%CF). The experiment followed a randomized complete block design with three replications. Various yield parameters, morphology, quality indicators, and nitrogen utilization were analyzed to assess the differences among treatments. The results indicated that all fertilizer treatments significantly increased the yield, morphology, quality indicators, and nitrogen utilization efficiency compared to the control. Specifically, 25%OM + 75%CF achieved the highest yield of 31.96 t hm-2, which was not significantly different from CF (30.18 t hm-2). 25%OM + 75%CF exhibited the highest values at 69.23 cm in tuber length and 75.86% in commodity rate, 3.14% and 1.57% higher than CF respectively. Tuber thickness and fresh weight of 25%OM + 75%CF showed no significant differences from CF, while OM and 50%OM+50%CF exhibited varying degrees of reduction compared to CF. Applying fertilizer significantly enhanced total sugar, starch, crude protein, total amino acid, and ash contents of D. polystachya (except ash content between CK and OM). Applying organic fertilizer increased the total sugar, starch, crude protein, total amino acid, and ash contents in varying degrees when compared with CF. The treatment with 25%OM+75%CF exhibited the highest increases of 6.31%, 3.78%, 18.40%, 29.70%, and 10%, respectively. Nitrogen content in different plant parts followed the sequence of tuber > leaves > stems > aerial stem, with the highest nitrogen accumulation observed in 25%OM + 75%CF treatment. Nitrogen harvest index did not show significant differences among treatments, fluctuating between 0.69 and 0.74. The nitrogen apparent utilization efficiency was highest in 25%OM + 75%CF (9.89%), followed by CF (9.09%), both significantly higher than OM (5.32%) and 50%OM + 50%CF (6.69%). The nitrogen agronomic efficiency varied significantly among treatments, with 25%OM + 75%CF (33.93 kg kg-1) being the highest, followed by CF (29.68 kg kg-1), 50%OM + 50%CF (21.82 kg kg-1), and OM (11.85 kg kg-1). Nitrogen partial factor productivity was highest in 25%OM + 75%CF treatment (76.37 kg kg-1), followed by CF (72.11 kg kg-1), both significantly higher than 50%OM + 50%CF (64.25 kg kg-1) and OM (54.29 kg kg-1), with OM exhibiting significantly lower values compared to other treatments. In conclusion, the combined application of organic and inorganic fertilizers can effectively enhance the yield, quality, and nitrogen utilization efficiency of D. polystachya. Particularly, the treatment with 25% organic fertilizer and 75% chemical fertilizer showed the most promising results.

“…As for their flowers, they are dioecious plants that at the beginning of spring present small, tubular and white flowers, without perceptible fragrance, in corymboid panicles formed by small axillary chapters; they take more than a month to produce all the flowers (Büyük et al, 2022;Gusmaini et al, 2022). In nature they are pollinated by bees.…”

Stevia rebaudiana se considera una importante planta medicinal que posee edulcorantes glucósidos bajos en calorías. El presente trabajo describe la comparación de tres genotipos de stevia (IBT 1, IBT 2 e IBT 3) en dos ambientes contrastantes simulados bajo condiciones controladas: Sullana en Perú; y Misiones en Paraguay (considerado como el centro de origen de la Stevia). Exploramos la distancia euclidiana como un indicador integrador para la selección simultánea de varios rasgos de stevia. Los científicos de plantas suelen registrar múltiples indicadores morfológicos, fisiológicos y bioquímicos en sus experimentos. Las evaluaciones de datos estadísticos comunes implican análisis univariados como la prueba t, Mann-Whitney y el análisis de varianza seguido de Tukey HSD. Sin embargo, dichos análisis no evalúan integralmente los efectos de los tratamientos experimentales porque cada indicador se analiza de forma independiente. Se calculó la distancia euclidiana de cada combinación de tratamientos al fenotipo ideal de las plántulas de stevia. IBT 2 cultivado en condiciones ambientales de Sullana presentó los mejores resultados integrales, mientras que IBT 1 mostró los peores resultados. El análisis indica que el uso de la distancia euclidiana podría contribuir a establecer una evaluación más integrada de los genotipos contrastantes de Stevia. Así también, puede ayudar a comparar diferentes rasgos fenotípicos.

Wild plants represent a potential source of urban landscape trees. Stranvaesia davidiana Dcne. is a member of the Stranvaesia Lindl. Genus, which belongs to family Rosaceae Juss. It has great ornamental value. It can contribute to urban color foliage and fruit species. However, the most effective fertilizer application strategy required for its cultivation is unknown. Therefore, we conducted an orthogonal experiment to investigate the fertilizer type and level (pure nitrogen) using ten experimental groups, including an untreated control group. Pot experiments were used to determine the growth indices of seedlings, including plant height, basal diameter, and chlorophyll content post-fertilizer treatment. This study explored the most appropriate fertiler application model for the growth of S. davidiana seedlings. The results revealed that enhanced seedling growth depended on the type and amount of fertilizer used, and their interaction. Fertilizer application increased the plant height by 2.67 cm to 12.26 cm, basal diameter by 0.39 cm to 0.75 cm, and chlorophyll content by 5.66 to 19.86. Among the different types of fertilizer, organic fertilizer increased the plant height by 0.42 cm to 9.59 cm and basal diameter by 0.01 cm to 0.05 cm, compared with the control group. Organic fertilizer had the maximum effect on seedling growth, especially at medium levels. The total growth of basal diameter and chlorophyll content was 1.58 ± 0.04 cm and 39.53 ± 2.37, respectively. Basal diameter is the most critical index in seedling reproduction . The study results suggest that the application of 4.06 g of organic fertilizer per plant was the most effective, and served as a basis for further field trials.
