2025
Mandeep Thapa | Basanta Kumar Rimal | Sujan Lamichhane | Arjun Kumar Shrestha
Seed hardiness threatens the growth and yield of okra by causing low and non-uniform germination. Seed priming is an effective, ecologically sound, and practical technique to promote germination. A study was conducted from March to July 2024 in Chitwan, Nepal, to evaluate the effectiveness of different seed priming treatments in enhancing the germination, growth, and yield of okra. The study used a randomized complete block design (RCBD) with four replications, under five different treatments: Control: no soaking, Hydro priming, NaCl @ 0.5%, KNO3 @ 0.5%, GA3 @ 100 ppm. Each plot consisted of twenty plants. Data on germination percentage, growth, and yield were recorded using standard methods. The collected data were examined employing MS Excel and R-studio version 4.3.2. Seeds primed with GA3 @ 100 ppm showed a significant rise in germination percentage (90 %), plant height at 30 DAS (17.50 cm) and 45 DAS (39.81 cm), leaf canopy diameter at 45 DAS (69.68 cm), fruit number per plant (9.15), fruit weight per plot (423.75 g), and maximum yield (1.41 t/ha), followed by other treatments. The leaf number per plant and fruit length were not significant. However, priming positively affected germination, growth, and yield parameters compared with the control (no soaking). The study found that priming okra with GA3 @ 100 ppm enhanced growth and yield. Seed priming with GA3 is recommended for okra production in Rampur, Chitwan.

Fatma Ruveyda Alkan | Buket Çetiner | Hüseyin Akşit | Samed Şimşek
This study investigated selected quality and functional characteristics of 17 hulled wheat accessions (Triticum monococcum and Triticum dicoccum) preserved in the Türkiye Seed Gene Bank, along using four modern wheat cultivars (Triticum aestivum L. and Triticum durum Desf.). The samples were evaluated regarding grain color parameters (L*, a*, b*), thousand kernel weight, and protein content. Furthermore, total phenolic content (TPC) and antioxidant activities were were analyzed using DPPH and FRAP assays. The differences between samples were statistically significant in terms of DPPH activity and protein content. Species-wise comparison demonstrated that T. monococcum and T. dicoccum had the highest average protein levels. The highest DPPH antioxidant activity was recorded in T. monococcum sample no. 10 (859.67 µg mL⁻¹), while the lowest was in sample no. 2 (532.58 µg mL⁻¹) of the same species. Significant variation was found across the samples for L*, a*, b* color values, Chroma (C), Hue angle (h°), thousand kernel weight, total phenolic content, and FRAP antioxidant capacity. The highest TPC was detected in T. dicoccum sample no. 17 (11.23 mg GAE g⁻¹), and the highest FRAP reducing power was found in sample no. 14 of the same species (22.10 mg TE g⁻¹). These findings demonstrate notable diversity among hulled wheats regarding the evaluated traits and suggest their potential as valuable genetic resources for wheat breeding programs.

Izuwa Iwanegbe | K.O. Durojaiye
The study produced milk drink that is high in protein and energy from soy beans and tiger nuts blends as well as to assess the beverage qualitatively and customer acceptability using response surface methodology (RSM). The principal raw materials used were soybeans and tiger nut. They were processed into milk at different formulations without using chemical preservative. Sensory evaluation, pH, titratable acidity as well as proximate and mineral compositions were determined. The results showed that the minimum and maximum colour score varied from 4.4 to 5.0. The quadratic model for colour was found to be significant (p<0.05) in tiger nut inclusion. The model equation obtained for colour = 4.50 + 0.048*A + 0.098*B + 0.019*A2 + 0.12*B2 + 0.18*A*B where A = Soybeans, B = Tiger nut. Mouth feel model’s F-value of 7.35 indicates that it was significant (p<0.05). Model terms are considered important when the “Probability > F” value was less than 0.05. The model for quadratic equation for mouth feel was 7.290. +5.00 -0.091*A -0.19*B -0.14* A2 -0.44* B2 +0.45* A*B. The model for the quadratic equation for Taste = +3.90 +0.030*A +0.020* B +0.21*A2 +0.056*B2 +0.075*A*B adequate precision = 3.65, corrected R2 = 0.29, R2 = 0.59 and the predicted R2 = -1.94. It was observed the pH values decreases with storage days from day 0 to day 8 for samples A, I and Z. On day 12, the pH values increased for all the samples except for sample M. The Titratable acid increased as the pH decreased. On the 0 day, sample A had value of 20.8 while sample M was 23.33. However, sample I increased from 0, 4, 8 and 12 days (20.19, 20.20, 22.47 and 23.73) respectively. Sample M had the highest protein content (3.52%), followed by sample A (3.21%), sample I (3.01%) and sample Z (2.02%). Sample Z had the lowest fiber content (0.30%), next was sample I (O.43 %), sample A (0.51%), and sample M (0.54%). The range of moisture contents was 81.03 to 82.04%. Conclusively, optimizing soybeans at 100g/ml with 40 g/ml of tiger nut could help to improve the sensory attributes such as colour, taste, mouth feel, flavor and overall acceptance. The formulation could influence shelf stability of product, bridge protein in-balance and reduction in malnutrition level.

The objective of this study was to evaluate the relationship between plasma leptin levels in the early and late luteal periods of cows and conception rate. In the present study, the ovsynch + progesterone (P4) protocol was employed in 50 Holstein cows. Blood samples were collected on the 5th and 18th days following artificial insemination, and the levels of leptin and progesterone were subsequently measured. Subsequent to artificial insemination, mean leptin levels in the early (day 5) and late (day 18) luteal phases of the cows were measured as 5.96 ± 2.54 and 8.02 ± 4.14 ng/mL, respectively. Levels of leptin in the blood of pregnant cows on both day 5 (9.01 ± 4.40 ng/mL) and day 18 (12.04 ± 6.49 ng/mL) were higher than those in the blood of non-pregnant cows (4.44 ± 3.83 ng/mL and 6.01 ± 4.93 ng/mL, respectively). The findings revealed that progesterone levels on the 5th day following artificial insemination exhibited higher mean values (2.11 ± 0.64 ng/mL) in pregnant cows as compared to non-pregnant cows (1.49 ± 0.51 ng/mL). Furthermore, a higher level of progesterone was observed on day 18 in pregnant cows (8.89 ± 2.01 ng/mL) in comparison to non-pregnant cows (5.22 ± 2.21 ng/mL) (p<0.05). The study revealed that levels of the hormones leptin and progesterone were elevated in pregnant cows during the early and late luteal phase, in comparison to non-pregnant cows. However, no correlation was determined between P4 and leptin. The conclusion drawn was that, while there was a possibility that leptin levels could have an effect on the process of pregnancy and implantation, no relationship was found between progesterone and leptin levels

Hilmi Kara | Nubar Yigit
The green peach aphid, Myzus persicae (Sulzer, 1776) (Hemiptera: Aphididae), has a broad host range including pepper plants and causes significant economic losses worldwide. The effectiveness of arbuscular mycorrhizal fungi (AMF) in inducing plant immunity against pests has recently been tested on various plant insect pests. This study aims to investigate the impact of AMF colonization on the demographic characteristics of M. persicae feeding on the Demre type pepper cultivar. AMF (Glomus spp.) was ensured to colonize the pepper plant roots and the experiments were carried out in the climate room with plant growth LEDs under 25 ± 2 °C, 65 ± 5 RH and 16:8 light:dark conditions. As a result of daily counts, raw data on the aphid biology were analyzed in the Two-sex MSChart program. The findings indicated that AMF application did not result in any statistically significant differences in the biological and life table parameters of M. persicae. Furthermore, similar results were obtained when the results were compared with the control in the 45-day population simulation. Determining the AMF-plant-insect interactions with different plant species and insect species will make a significant contribution to increasing the success of biological control and preserving the natural balance.

Ercan Yeşilırmak
Plants need to accumalate heat to complete a particular or whole growth period. This accumalation depends on temperature thresholds above or below which plant growth ceases, and on air temperature. It can be speculated that more heat accumulation is available for plants due to rapid warming within three or four decades. This study presents more recent heat accumulation for plants, quantified using a useful index called growing degree day (GDD), for five locations (Söke, Kuşadası, Aydın, Sultanhisar and Nazilli) in Aydın, Türkiye, during the latest climatic normal period from 1991 to 2020. GDD values were calculated both in monthly basis from March through October, and in daily basis from March 1st to October 31st. Monthly GDD averages, as expected, showed a pattern that increased from March to July or August, then decreased thereafter till October. Range and standart deviation showed approximately an opposite pattern, suggesting higher uncertainity in relatively colder months. The results are expected to provide farmers or agricultural practitioners with the latest averages of GDD to predict plant growth and development.

‘Mandacaru’ (Cereus jamacaru P.) is a native species from the vegetation of the Brazilian North East “Caatinga”, and its fruits could become an important nutritional source for the population of semiarid regions, although it is still not commercially exploited. This work was carried out to evaluate the physical and chemical characteristics of the pulp and peel of ‘mandacaru’ fruit from the Curu Valley, Ceara State, Brazilian North East. ‘Mandacaru’ fruits were harvested and transported to the Embrapa Tropical Agroindustry Laboratory, where approximately 2 Kg of mature and firm fruits were selected for evaluation. These fruits were washed, sanitized and placed under cold storage for future analysis. The fruit pulp and peel were evaluated for: pH, soluble solids (SS), ascorbic acid and total reducing sugars. The experiment was carried out in a completely randomized design, with four replicates. The peel of ‘Mandacaru’ fruit presented pH 4.42, being higher than pulp at pH 4.40. Ascorbic acid content was 100 mg/100g -1 in the pulp, and 80 mg/100g -1 in the peel. A significant difference in SS was detected between pulp and peel, which were 11% and 5%, respectively. On the other hand, fruit pulp presented higher percentage of reducing sugars of 5.76%, as compared to that found in the peel of 1.53%. | O mandacaru (Cereus jamacaru P.) é uma espécie nativa da vegetação da caatinga, onde seus frutos podem constituir uma agradável fonte de alimento, embora ainda não sejam explorados comercialmente. O trabalho foi realizado com o objetivo de avaliar as características físico-químicas da polpa e da casca dos frutos de mandacaru oriundos do vale do Curu-CE, Nordeste do Brasil. Os frutos foram colhidos e conduzidos às condições de laboratório da Embrapa Agroindústria Tropical, onde para as análises foram selecionados cerca de 2 kg da matéria-prima, sendo os frutos escolhidos aqueles maduros e firmes. Depois foram lavados, sanitizados e submetidos a armazenamento sob refrigeração para as análises posteriores. Os frutos foram caracterizados quanto ao pH, sólidos solúveis (SS), ácido ascórbico e açúcares redutores totais. O delineamento foi inteiramente casualizado, com quatro repetições. A casca do fruto apresentou valor de pH de 4.42, superior ao da polpa que foi de 4.40. Os teores de ácido ascórbico para a polpa foram de 100 mg/100 g de polpa e casca de 80 mg/100 g de polpa. Para os teores de SS, constata-se diferença significativa entre os valores da polpa e da casca, com 11% e 5%, respectivamente. Portanto, a polpa do fruto apresentou maior porcentagem de açúcar de 5.76, em comparação àquela encontrada na casca de 1.53.

Anaplasmosis, a vector-borne haemoparasitic disease, poses a significant threat to animal health. This study investigated the prevalence and associated risk factors of anaplasmosis in goats within the Chattogram district of Bangladesh. The research was conducted at the SA Quadery Teaching Veterinary Hospital (SAQTVH), Chattogram Veterinary and Animal Sciences University (CVASU), involving observations of 202 goats. Blood samples were collected from the ear veins of 44 goats. Thin blood smears were prepared, stained with Giemsa, and examined under a microscope. Statistical analysis was performed using Chi-square tests in SPSS Statistics version 26. The study found that goat rearing systems significantly influenced infection rates (P < 0.05). Anaplasmosis was more prevalent in goats displaying pale mucous membranes and symptoms such as fever or weakness (P < 0.05). To mitigate the disease, strategic control measures, including vector reduction and routine health monitoring, are recommended.
