Ahmed Ibrahim Khalaf Albajary — 2026-03-19

Potassium is a fast-moving element within plants and plays an influential role in regulating and arranging the osmotic pressure within the cell, as well as working to balance the cations and anions in the cell cytoplasm. A field experiment was carried out in Salah al-Din Governorat, to study the effect interaction of zinc from two sources, chelated and mineral, at different potassium levels on wheat indices. The experiment was designed according to (RCBD) and included two factors: the first factor Zinc fertilizer (chelate, mineral) at three levels for each it is (stander) for both, zinc mineral (10, 20) Kg h^-1, zinc chelate (10 ,20) Kg h^-1 and the second factor is potassium sulphate (K₂SO₄) at levels (0, 80, 160 ,240) Kg h^-1. The results showed the highest value interaction of physiological efficiency (PE) was obtained from the combination of (Zn₄ K₂) and significantly different from other treatment which reached an average of (15926.70) Kg Kg^-1 while the treatment (10Zn chelate Kg ha^-1 + 160 K Kg h^-1) gave the highest value for the Agronomic efficiency (AE) trait which significantly outperformed the rest of the traits within the same potassium fertilizer level as it reached (135.5) Kg Kg^-1, The treatment (Zn₃ K₃) also gave the highest rate of Apparent recovery efficiency (ARE) which was significantly superior, reaching (1.93 ) % , As for the Utilization Efficiency (UE) it reached the highest value (28656.4) ) Kg Kg^-1 which was recorded by the treatment (Zn₃ K₂).

Habeeb A. Yahya — 2026-03-24

The eggplant plant (Solanum melongena L.) is the annual vegetable grown in the warm regions and consider one of the important vegetable crops in the world, due to the highly nutritive values, and medicinally benefits. One of the strategies to enhance production is through the improvement of cultivation techniques. The Research was conducted at the Nursery of Department of Crop Science, Faculty of Natural Resources and Environmental Studies, University of Kordofan. Elobeid, Sudan. The aim of this research is to determine the effect of NPK fertilizer and plant density and to find the best dose and density on the growth and yield of eggplant. Six treatments in two seasons were used: 1 plant 0g of NPK, 2 plants 0g of NPK, 1 plant 5g of NPK, 2 plant 5 g of NPK, 1 plants 10 g of NPK, 2 plants 10g of NPK. The treatments were arranged in a Randomized Complete Block Design (RCBD) with four replicates. Parameters studied included number of leaves/plant, leaf length (cm), Leaf width (cm), stem length (cm) Number of branches/plant, Number of flowers/plant, fruit length (cm), fruit width (cm), and fruits yield (ton/feddan). In the first and second season the statistical analysis of the data showed significant differences between the treatments on the number of leaves per plant, leaf length, leaf width, stem length, number of branches per plant, number of flowers per plant, fruit length, fruit width, and fruits yield. The treatment 2pt 10g NPK had highest values of number of leaves/ plant (84 and 79), fruits length(20.8 and 22.18cm), fruit width (9.5 and 7.79 cm), fruits yield (9 and 34 ton/ha) while the lowest values (10 and 21), (10.2 and 15.67 cm) , (4.5 and 4.02 cm), (4 and 17 ton/ha) where obtained in the treatment 1 pt 0g NPK in 2023 and 2025 respectively, the results showed that the application dose of 10g of NPK and density 2plant/hole gives good and effective results compared to a dose of 5g NPK either with one or two plant.

In Vitro Propagation and Rooting Ability of Wild Plum Genotypes (Prunus cerasifera Ehrh.)

Hürü Altan — 2026-03-26

In this study, the propagation and rooting ability of wild plum (Prunus cerasifera Ehrh.) genotypes collected through selection was tested under in vitro conditions. During the propagation phase, 4 different BAP doses (0.5, 1.0, 1.5, 2.0 mg/L^-1) were applied to shoots from 6 genotypes (nos. 4, 9, 33, 42, 47, 49), while 5 different IBA doses (0.5, 1.0, 1.5, 2.0, 2.5 mg/L^-1) were applied during the rooting phase. During the experiment, measurements were taken of the average shoot number, shoot length, leaf number, average root number, number of rooted plants, and root length for each genotype. As a result of the analyses, while the shoot length remained short at the doses with the highest shoot count, the highest shoot length was recorded at the 2 mg/L^-1dose, where the shoot count decreased, for genotype 47 (4.97 cm). The average shoot number was 2, and genotype 49 was found to have the lowest shoot number in the 2 mg/L^-1BAP medium. Genotype 47 reached the highest plant number 100, in the 1 mg/L^-1BAP medium at the end of the third subculture. Again, in the 2 mg/L^-1BAP medium, genotype 47 stood out with a shoot length of 4.97 cm and a leaf count of 16. The best rooting percentage was obtained in genotype 42 at a 2.0 mg/L^-1IBA dose (88.71%) and in genotype 4 at a 1.5 mg/L^-1 dose of 1.5 mg/L^-1 (84.00%). Based on the general averages, the most effective IBA dose was 1.5 mg and 2 mg/L^-1), with the highest rooting rate calculated at 68%. The 2.5 mg/L^-1 IBA dose produced the highest number of roots and root length. The study showed that tissue culture protocols cannot be uniform and that genotypes respond differently to hormone doses. The P. cerasifera type of plum is an important species due to its strong adaptability, its cultivation being more economical than other species, its high tolerance to biotic and abiotic environmental conditions, and its preference as a rootstock. Detailed examination of these genotypes is required. It is important in terms of introducing new materials to breeding studies and conserving genetic resources.

Impact of Auxin Rates on Vegetative Growth and Nutrient Uptake of Ornamental Palm Varieties in Ogbomoso, Southwestern Nigeria

O. F. Sadiq — 2026-03-30

Ornamental palms are valued for their aesthetic appeal and landscape versatility, contributing significantly to urban greenery and nursery based horticultural enterprises. Despite their economic and ecological importance, vegetative growth and nutrient efficiency in palms are often constrained by suboptimal management practices, including inadequate use of plant growth regulators. This study evaluated the effects of different auxin growth hormone rates on vegetative growth and nutrient uptake of selected ornamental palm varieties in southwestern Nigeria. The experiment was conducted in a screen house at the Teaching and Research Farm, Ladoke Akintola University of Technology (LAUTECH), Ogbomoso. Factors considered were Three ornamental palm varieties (Queen palm, Golden palm, and Fan palm) subjected to five auxin rates (0, 0.2, 0.4, 0.6, and 0.8 ml/L) in a 3 by 5 factorial arrangement using a completely randomized design with six repetitions. Data on plant height, number of leaves, stem girth, and nutrient uptake were collected and analyzed using ANOVA and treatment means separated by least significance difference at 5% probability level. Results showed that auxin rates, variety, and their interactions significantly (p ≤ 0.05) influenced all measured growth parameters and nutrient uptake. The 0.6 ml/L auxin rate consistently produced superior vegetative growth, while 0.8 ml/L enhanced nitrogen and potassium uptake. Among the varieties, Queen palm exhibited the greatest overall height and leaf production, whereas Golden palm recorded the highest stem girth and nutrient assimilation efficiency. Significant interaction effects indicated that varietal responses were strongly dependent on hormone concentration and plant age. The study demonstrates that auxin application at 0.6 ml/L, enhances vegetative growth and nutrient uptake of ornamental palms, with Golden and Queen palms showing superior performance.
