Tree Phenology

Different fruit thinning methods were tested on ‘Sensation’ mango trees over two seasons in a trial conducted in Northern Province, South Africa. The objective of the study was to select the best thinning intensity and method based on different parameters. Thinning was carried out in October prior to the occurrence of excessive natural fruit drop. When fruits were thinned to one and two fruits per panicle, fruit number, weight and yield per tree at harvest were all increased. When 50% of the panicles were thinned there was an increase in the fruit retention potential of the trees as well as in the size and quality of the fruit produced. Large fruits were, however, prone to certain physiological problems. Chemical thinning with Corasil.E produced very small fruits with an increased percentage of ‘mules’ (fruit without seed). Trees subjected to severe thinning intensities showed earlier recovery of starch reserves and better vegetative growth than the control.

The experiment was conducted during the fruiting season of 2005-06 to  investigate the effects of paclobutrazol in manipulating the harvesting time,  increasing yield and quality in mango (Mangifera indica) cv. BARI Aam-3  (Amrapali) plants at the BAU Germplasm Centre, FTIP, Department of  Horticulture, Bangladesh Agricultural University, Mymensingh. Paclobutrazol  at 2500, 5000, 7500, 10000 ppm, and control (water application) and two times  of application (15 October and 15 December) were included in the study as  treatments. Soil drench application of paclobutrazol at 10000 ppm and 7500  ppm on 15 October was more effective in suppressing vegetative growth i.e.  terminal shoot length, number of leaves and leaf area compared to control. Both  7500 ppm and 10000 ppm paclobutrazol applied as soil drench on 15 October  caused earlier panicle emergence by 19 days as well as harvesting by 15 days  compared with control. Applying paclobutrazol at 7500 ppm on 15 October  produced the highest number of fruits as well as yield per plant and the heaviest  fruit compared with the lowest yield in control. Paclobutrazol at 7500 ppm  applied on 15 October also resulted in higher edible portion, lower stone pulp  ratio and peel pulp ratio, longer shelf life, higher TSS, increased vitamin C,  lower titratable acidity, higher dry matter, reducing, non-reducing and total  sugar contents as compared to control plants. The present results suggest that the  application of paclobutrazol at 7500 ppm in October enhances yield and quality  in mango. DOI: http://dx.doi.org/10.3329/bjar.v37i2.11238 Bangladesh J. Agril.

The effects of 7 pruning treatments were studied in 2 mango cultivars (‘Keitt’ and ‘Tommy Atkins’) in the Hoedspruit region of the Northern Province of South Africa. Trees that received panicle pruning (during full bloom) treatment at the point of attachment were observed to be induced for synchronised re-flowering, and also attained early fruit set and more fruit per panicle than the other panicle pruning treatments. Trees on which renewal pruning (early in the season when fruits were on the tree) as well as postharvest pruning treatments were applied, have been observed for development of adequate number of productive inflorescences per season in an early-maturing cultivar, Tommy Atkins. Postharvest pruning treatments also resulted in significant increase of postharvest vegetative growth in both cultivars. Promising improvement in yield could be expected after the second season from panicle pruning in Tommy Atkins. The fruit quality, especially with regard to total soluble solids (TSS), was also greatly improved due to the applications of renewal and postharvest pruning treatments. Inflorescence removal together with apical whorl of leaves subtending the inflorescence had adverse effects for the various parameters studied in both cultivars.

Fishing tourism is one of the modern types of tourism that is aimed at meeting the needs of a certain segment of tourists in fishing. This type of tourism is organized by special enterprises to favorable places for fishing. Fishing tours in most cases include specialized services such as: fishing license, tackle rental, boat rental, instruction and joint fishing with a qualified fishing guide, as well as services aimed at preserving and preparing the fish caught. Such countries as Finland, Norway, Egypt, Namibia, South Africa, Iceland, Sweden, Slovakia, Thailand and Israel occupy high positions in the international market of fishing tourism and are famous for their fish resources. As for fishing tourism in Russia, the demand for fishing tourism is currently increasing. Tourist companies are engaged in expanding the geography of fishing tours and improving the quality of service, which affects the increase in demand for this type of tour. The analysis of the potential of the Astrakhan region, carried out in the article, allowed us to identify opportunities for the development of organizational fishing tourism.

The primary purpose of an improved water supply and sanitation is the achievement of acceptable health and hygiene standards as well as the sustainable improvement of the environment. Many governments recognize this and so they budget for large sums of money to improve these services to the communities. The purpose of this study was to investigate the different gaps in environmental health and hygiene practices with the aim of suggesting a strategy of improving this in the Northern Province of South Africa. To do this, 231 households and 30 schools were surveyed. Workshops and visits to different government departments were also used. This paper reports the results from this study which indicate that the situation in schools was not any better than that in households, with more than 90% of the villages still dependent on the unimproved pit latrines and 56,6% relying on standpipes which were (70% of the time) non-operational. The main problems identified seem to those associated with implementation and maintenance. The study concludes that with proper training of the water committees and their active involvement with the government and NGOs, environmental health and hygiene problems can be minimized or eliminated.
