The effects of root pruning on the vegetative growth and fruit quality of six-year-old Zhanhuadongzao (<I>Ziziphus jujube</I> Mill.) trees were evaluated. Three root pruning treatments (severe, moderate and light degree) were conducted at the distance of 3, 5 and 7 times trunk diameter from trunk on both inter-row sides of the trees, respectively. The results showed that the severe root pruning decreased the length of primary branch by 27.9% and the number of primary branches by 12.1% in contrast to the control of no root pruning. Compared to the control, both severe and moderate root pruning had no apparent effects on nitrogen, phosphorus and potassium contents of leaves after 35 days, but had significant effects after 161 days. Severe root pruning had larger effectiveness of controlling vegetative growth than the moderate one. By root pruning, the contents of vitamin C and total sugar were increased but the content of cypermethrin was decreased in fruits and no effects were found on total acid content of fruit and yield at harvest. In the rhizosphere soil, root pruning decreased the microbial populations and enzymes activities but increased the concentrations of cypermethrin, available nitrogen, phosphorus and potassium. It is proposed that the removal of root at 3 times trunk diameter distance from trunk was feasible to regulate the vegetative growth and fruit quality of Zhanhuadongzao tree.

This study was aimed at observing the effect of the grafting of tomato plants on morphological (vegetative growth), production and nutritive characteristics (quantity and quality of production). For this purpose, the ‘Lorely F1’ cultivar was used as a scion grafted onto the ‘Beaufort’ rootstock. Plants were cultivated with a stem and two stems. The observations collected in this study were concerned with the characteristics of plant growth. The studied morphological characteristics were plant height, stem diameter and number of leaves, and the studied production characteristics were the characteristics of fructification and productivity (the average number of fruit per plant, the average weight of the fruit, production per plant). Particular attention was paid to the nutritional characteristics of the fruit, to the fruit quality (total soluble solids, total sugar, acidity, vitamin C, antioxidant activity (by the Trolox method) and the contents of lycopene and beta-carotene). The results showed that grafting positively influenced the growth and production characteristics. Grafting of tomato plants had an appreciable effect on the vegetative growth of the variant 2-grafted tomatoes with a stem. The best option in terms of productivity and production was the variant 3-grafted tomatoes with two stems, which yielded 9.2 kg per plant. Fruit quality was not improved in any of the grafted variants.

The efficiency and responsiveness agronomic to the main macronutrients is becoming increasingly important due to the risk of supply, since it is a finite resource. In addition, excess fertilizer decreases the quality of water and air. Thus, the objective of this work was to assess the corn hybrids in terms of their efficiency and responsiveness to nitrogen (N), phosphorus (P) and potassium (K), and identify the ones most suitable for fresh consumption, according to the product type and technological level to be adopted by the farmer. The randomized complete block design in a 10 &times; 3 (hybrids and doses) factorial scheme was adopted for the experiment, with three replications, for two season crops (2013/14 and 2014/15). Ten hybrids (2B512PW, 2B587PW, 2B707PW, 30F35HR, 30F53YH, AG1051, BRS1055, BM3061, P3646H e P3862YH) were used in isolation under low availability (without application) and partial, of N, P and K, in an isolated manner, also evaluated under the recommended dose, aiming at fresh consumption. The most efficient and responsive hybrid must first be identified in isolation, based on the availability it is subjected to and later, by its sale, focused on fresh consumption. The hybrids indicated for low availability (low technological level) were BRS1055 and 30F53YH, with respect to responsiveness or agronomic efficiency, the hybrid P3862YH was the one that presented the best performance and indicated for technological levels of medium to high, considering the classification obtained for the nitrogen, phosphorus, and potassium for production vegetable corn.

The study was conducted in the nursery of Hort. Dept., College of Agriculture and Forestry, Mosul University, Iraq, during 2018 season to study the response of budded "Zaghinia" apricot on seedlings rootstock to bio, organic and chemical fertilizers, and their effects on seedling growth. The studied factors were as follows: Bio fertilizer Fulzyme (0,1and 2 g. seedling-1 ), organic fertilizer (Rice residue) (0, 1 and 2 kg. seedling-1 ) and DAP fertilizers (0, 5 and 10 g. seedling-1 ). The study was performed by using split-split plots within factorial experiment in randomized complete block design (RCBD), with 3 factors and 3 replicates, by using 6 seedlings for each treatment. Treatment means were compared by using Duncan multiple levels at 5% p. the most important results obtained were as follows: 1 and 2 gm.seedling-1 of bio fertilizer (Fulzyme) and Chemical fertilizer (DAP) at the levels 5 and 10 g. seedling-1 affected significantly resulted in a significant increase in soil available nitrogen, while the addition of organic fertilizer (rice residues) and for both levels 1 and 2 kg. Seedling-1 gave a significant increase in nitrogen, phosphorus, ready-made potassium and pH of the seedling soil, and the bilateral interaction had a significant role in the growth of seedlings, especially the treatment of the interaction between the fertilizer (Fulzym) and organic fertilizer (Rice residues), which have a significant effect in giving the best results in available nitrogen, phosphorus and potassium in the soil, and the triple interference also gave a significant increase in all studied traits.
