In this work, the influence of different concentrations of indole-butyric acid on the development of roots, one-year-old and two-year-old hardwood cuttings (Sambucus nigra L.) was investigated. Both types of cuttings were treated with three different concentrations of indole-butyl acid in liquid form (500 ppm, 800 ppm, and 1000 ppm), including the control variant of one-year-old and two-year-old hardwood cuttings (without the application of hormones). The parameters examined at the end of the experiment were: the percentage of rooting of the cuttings depending on the hormone treatment, the length of the adventitious roots depending on the hormone treatment, and the fresh mass of the roots, also depending on the hormone treatment. The use of indole-butyl acid in a concentration of 800 ppm proved to be the best because it had the greatest effect on increasing the value of all tested parameters of the cuttings. 

This work aimed to study the effect of pruning on the uvometric characteristics of the Merlot and Vranac wine varieties in the Trebinje region. The research was carried out in 2018, each variety had two variants of pruning, and each variant had three repetitions. The load levels of buds in this study were 11 (Variant I) and 9 (Variant II) buds per vine. The most important uvometric parameters of the tested varieties were measured. As an experimental factor, the variety, had a statistically significant influence on most of the investigated indicators, while pruning did not. The research carried out in Trebinje shows that both tested varieties can be successfully grown in the mentioned locality because the climatic conditions are suitable for their cultivation. 

Varietal correct, healthy and quality planting material is the basis of successful fruit production. Mistakes that are made in the choice of planting material when planting are, unfortunately, very common, they are noticed late and cannot be corrected. During grafting, there is a change in the epibiot under the influence of the hypobiote, which is numerous and diverse.This paper presents the results of the influence of two apple cultivars (Idared and Jonagold) on the growth dynamics (through six measurements during the growing season), seedling height, rootstock and stem diameter. The direction of the significant difference is not the same in all measurements, sometimes the average is higher for the Idared variety and sometimes for the Jonagold variety. Based on that, we cannot conclude that the apple variety has a statistically significant effect on seedling height and steam diameter. But during the influence of the variety on the diameter of the steam, it can be concluded that the apple variety has a statistically significant effect on the diameter of the rootstock.When it comes to the impact of branching, the research results show that it is significant for all research parameters.

During the three-year study of the influence of pruning on the phenological development and yield of the Alphonse Lavalle variety in the Mostar area, three pruning variants (28, 30 and 40 buds / vines) were applied in four replications. The phenological development of the variety took place within the limits of the average and in accordance with the temperature conditions. The total number of developed shoots and the number of bearing shoots was the highest in 2013 (total 21.72, birth rate 21.25), and the lowest in 2012 (total 18.67, birth rate 18.56). The highest yield of grapes per vine was recorded in 2013 (17.73 kg), and the lowest in 2011 (9.01 kg). The number of bunches per vine was the highest in 2013 (33.94), and the lowest in 2011 (26.71). Pruning variant III had the largest number of total (21.79) and native (21.64) shoots, and variant I the smallest (total 18.46, native 18.17). The highest yield of grapes per vine was recorded in variant II (14.47 kg), and the lowest in variant I (12.05 kg), while the number of bunches per vine was uniform in variants II (31.37) and III (31, 51).

The study of the effect of various types of pruning on fruiting of Muscat Bleu grape variety in the conditions of Herzegovina lasted for three years. Three pruning variants (28, 32 and 40 buds/vine) were applied in four repetitions. The yield of grapes per vine and the number of clusters per vine was the highest in 2011 year (10.30 kg and 45.98). The yield of grapes per vine (7.59 kg) was the smallest in 2012, and the number of grapes per vine in 2013 (25.93). The total number of productive canes per vine was the highest in 2012 (26.62), and the lowest in 2013 year (total number of productive canes per vine 22.65, number of productive canes per vine 22.47). Pruning variant III had the highest levels of these parameters in all three experimental years, and variant I the lowest.

The aim of this study was agro-pomological evaluation of ‘Clery’ strawberry cultivated in three different growing systems (open field, under low and high tunnel). The experiment was conducted during three seasons (2013-2015) at a commercial orchard in Celic (North eastern Bosnia and Herzegovina). By cultivation system of ‘Clery’ strawberry under high tunnel were achieved better results related to the development of crowns, yield per plant, fruit size, the ratio of marketable fruits and content of soluble solids in the fruit. Obtained results indicate that it is possible to adopt cultivation system in the strawberry culture in order to improve the total and marketable yield as well as fruit quality.

Talking about a cucumber (Cucumis sativus L.) widespread means that it should be immediately emphasized how widespread it is in our country (Bosnia and Herzegovina), both in food and production. Based on that, there is an urgent need for quality and disease-resistant varieties/hybrids produced by technology which reduces the possibility of disease emergence. Greenhouse production of grafted cucumber in Bosnia and Herzegovina in recent years is experiencing significant expansion.Grafted plants of the cucumber hybrid ‘Charta’ were comparatively analyzed with the non-grafted, in order to record the main morphological and productive differences between them.The examined parameters were the number of lateral roots, number of roots hairs, root mass, leaf length and yields.The results of this study show that grafted cucumber in relation to non-grafted achieves a higher yield (161.64±20.82 kg/50m2), while morphological characteristics were mostly similar. Significant differences were observed only in the number of lateral roots (18.00±2.65).

This study aimed to provide a more in-depth analysis of the fruit quality of three table grape varieties: 'Moldova', 'Lasta', and 'Italia', cultivated in the Žepče area (Bosnia and Herzegovina). The findings from the comparative analysis indicated substantial variations in grape quality among the studied varieties. 'Moldova' grapes exhibited significantly higher total soluble solids and pH values than those of the other table grape varieties. 'Moldova' also had higher total phenolic and flavonoid contents in the grape skin relative to 'Italia' and 'Lasta'. On the other hand, 'Italia' variety showed the highest titratable acidity, followed by 'Lasta' and 'Moldova'. Total phenolic and flavonoid contents were highly positively correlated with the antioxidant capacities of all analyzed grape samples, suggesting that phenolic compounds contribute significantly to the antioxidant properties of grapes. Study results also indicated that all heavy metal levels tested in grapes were below the threshold limits, which was expected considering that the experimental soil was not contaminated with the heavy metals being assessed. Overall, the results from the study have shown that all grape varieties studied hereby displayed a satisfactory level of quality based on key chemical parameters, and that the experimental area is quite favorable for their cultivation.
