[PRODUCTIVITY AND FRUIT QUALITY OF CANTALOUPE AT DIFFERENT RATES OF FRUIT THINNING AND NPK FERTILIZER APPLICATION]. Productivity and fruit quality of cantaloupe depend on the availability of nutrients and the number of fruits maintained. The aim of this study was to compare the productivity and fruit quality of cantaloupe at different rates of fruit thinning and NPK fertilizer application. The research was conducted in August-October 2020 on street Kapuas V, Lingkar Barat Village, Gading Cempaka District, Bengkulu city.

Abstract:

The apple tree usually has heavy fruit set but to improve the individual fruit size, apple growers reduce the number of fruits by thinning. The present study was carried out to assess yield and quality of apple fruit as influenced by fruit thinning. The experiment was carried out in a randomized complete block design (RCBD), with two factors, viz. time of thinning (factor 1) and amount of thinning (factor 2). Factor 1 included thinning after 2 wk of fruit set and 4 wk after fruit set; Factor 2 included one fruit per cluster, two fruits per cluster, three fruits per cluster, and four fruits per

Abstract:

This study examined the effects of stem-pruning and fruit-thinning on the yield of marketable watermelon fruit (>5 kg) and watermelon quality after four days of postharvest storage at 22 °C (marketing simulation). We examined the fruits from non-grafted and grafted plants (TZ and Nurit rootstocks) for two consecutive years. Grafting increased the number of marketable fruit per m2. The weight of the average marketable fruit was increased by pruning, but was not affected by thinning or by the choice of rootstock. The level of total soluble solids was higher among fruits from Nurit rootstock.

Although these are crucial responses to thinning, they are not always associated with an increase in crop value, which is the commercial justification for thinning.

Thinning, whether mechanical or chemical, prevents the development of some fruits, allowing the remainder to become larger and more marketable. Chemicals used for thinning either prevent fruit set or increase the proportion of fruits that fall in the “June drop”; some, however, are effective even after this drop. The mechanisms involved in blossom thinning are straightforward. Either pollination is prevented, or some of the flowers are injured, causing their abscission. The mechanisms involved in fruit thinning are more complex; physiologists continue to debate the effects of thinning agents o

Plum is the most important fruit crop for cultivation in Serbia. However, a small amount of plum fruit is sold as fresh fruit due to its poor quality. In order to improve fruit quality and obtain regular and high yield chemical blossom thinning agents were applied. The experiment was conducted on seven-year-old plum trees of cultivar `Stanley` which were planted on distance 5x5 m. Ammonium thiosulphate and ethephon were applied in the next treatments: 1) ammonium thiosulphate 1.5% (ATS); 2) ethephon 0.015% (E); 3) ammonium thiosulphate 1.5% + ethephon 0.015% (ATS + E); 4) hand thinning (HT); 5

Crop load management in intensive apple orchards must be done precisely to produce a high yield with marketable fruit size. It also ensures the formation of flower buds on the tree for the next season and prevents alternative bearing. In addition to pruning, flower and fruit thinning is another management method that has a major impact on crop yield. Compared to other methods, chemical thinning is the cheapest, can be done quickly and allows fruit thinning at the right time, which guarantees better fruit quality.

Peach [Prunus persica (L.) Batsch] fruit thinning was used to reduce the competition for assimilates among peach fruits and to identify periods of source- and sink-limited growth during development. Individual fruit size, based on diameter or calculated dry matter accumulation, increased in trees with lower crop loads compared to fruits of unthinned trees in three peach cultivars. Relative growth rate analysis indicated that peach fruit growth was apparently limited by the assimilate supply (source-limited) or by its genetic growth potential (sink-limited) during specific growth periods.

Chemical fruit thinning is a common practice in apple (Malus x domestica Borkh.) orchards for achieving high quality fruits, reduced costs of hand-thinning and promote return of flowering. Hand thinning is a common and high cost practice, not only due to the labor involved, but also because seedling and vigorous clonal rootstocks result in large trees. The chemical thinning agents: Ethephon (ETH), Carbaryl (CB), Naphthalene acetic acid (NAA), 6- Benzyladenine (6-BA), and fish oil were evaluated on ‘Golden Delicious’ and ‘RedChief Delicious’ apple trees in 2004 and 2005.
