Effect of planting density on growth, yield and fruit quality of apple cv. Jeromine

The paper examines the influence of three clonal rootstocks ('Pixy', 'Fereley' and 'St. Julien A') along with seedlings of Myrobalan (control) on the growth, yield and fruit quality of the plum cultivar 'Cacanska Rana'. Research was conducted in the area of the Belgrade Danube basin for the six-year period (2013-2018). In comparison to control, all three clonal rootstocks have shown a significant effect on the decrease of vigor expressed as a trunk cross-sectional area. The lowest vigor was found in trees on the 'Pixy' rootstock, then on 'Fereley' and 'St. Julien A' rootstocks. Regarding the rootstocks 'Fereley' and 'St. Julien A', significantly higher fruit set and yields were achieved in comparison to control. Clonal rootstocks induced an increase in the yield per hectare ranging from 72% to 93% compared to Myrobalan. The highest yield efficiency was found in the trees on the 'Fereley' rootstock, followed by the yields observed in the trees on the 'Pixy' and 'St. Julien A' rootstocks. Significantly higher fruit weight compared to control was obtained in the trees on the 'Fereley' rootstock. Rootstocks did not show any significant effect on the soluble solids and total acid contents of the fruit. Based on the results obtained, it can be concluded that all three clonal rootstocks showed better results than Myrobalan, and can be recommended for establishing intensive plum plantations with higher planting density. The best results in terms of yield and fruit quality were obtained with the 'Fereley' rootstock.

Two training systems(open lyre and Kniffin) with two planting densities(3.3 m × 1.5-1.1 m and 1.8 m × 1.5-1.1 m, R × V, respectively) were evaluated for their effects on growth, yield, and fruit quality of fourteen grapes grafted to SO4. Cane pruning weights of vines grafted to SO4 rootstocks averaged 268.1 kg/10a. Chenin Blanc, Cabernet Sauvignon, and Clairette grapes had greater cane pruning weights. Pruning weights of vines trained to the Kniffin system with 1.8 m × 1.1 m spacing were greater. Fruit yields of young vines averaged 438.6 kg/10a, and SV 5276, Carignane, and Ugni Blanc grapes were more productive while Riesling, Grenache, Chenin Blanc, Muscat de Frontignan grapes were less productive. Yields of grapevines trained to the Kniffin system with 1.8 m × 1.1 m spacing were more productive. Fruit quality was less affected by training system and planting density, but significant varietal differences were recognized.

Clinoptilolite Zeolite

Papaya cultivation on nutrient deficient acidic peat soils causes poor growth, yield, and fruit quality of this crop. Alkalinity and the high affinity of clinoptilolite zeolite (CZ) for macronutrients could improve pH, nutrient availability, and papaya productivity on peat soils. A one-year field experiment was conducted to determine the effects of CZ on: (i) soil ammonium, nitrate, P, and K, and (ii) growth, yield, and fruit quality of papaya grown on a peat soil. Treatments evaluated were: (i) different amounts of CZ (25%, 50%, 70%, and 100% of the existing recommended rate of CZ) + NPK fertilizer, and (ii) NPK fertilizer alone. The peat soils with CZ improved pH, ammonium, nitrate, P, and K availability because of the sorption of these nutrients within the structured framework of the CZ. Co-applying CZ (70% to 100%) and NPK fertilizers improved the NPK contents in papaya leaves and the growth, yield, and fruit quality of papaya because of the significant availability of ammonium, nitrate, P, and K in the peat soil for their optimum uptake by the papaya plants. Ability of CZ to buffer the soil pH reduced the need for liming. It is possible to use CZ to improve papaya productivity because CZ can regulate nutrient availability.
