Abstract The effects of production light level on growth of crapemyrtle were evaluated as a means of accelerating the development of tree-form crapemyrtles (Lagerstroemia spp.). By the end of the first growing season, plant height and shoot length of ‘Fantasy’ and ‘Tuscarora’ were greater when grown under 50 or 80% shade than when grown in full sun. By the end of the second growing season, height and shoot length of all three cultivars grown under one or both shade levels were greater than those of plants grown in full sun. In a second experiment, ‘Carolina Beauty’ and ‘Tuscarora’, but not Dynamite™, were taller at the end of the first growing season when grown under 50 or 80% shade than when grown in full sun. Flowering of all cultivars grown under shade was suppressed or delayed. Caliper of Dynamite™ and ‘Tuscarora’ at the end of the first growing season was greatest when grown in full sun, while production light level had no effect on caliper of ‘Carolina Beauty’. At the end of the second season, during which all plants were grown in full sun, there were no height, caliper, or flowering differences of any cultivar due to previous production light level, except for less caliper growth of ‘Tuscarora’ previously under 80% shade compared to plants grown in full sun.

Abstract The effects of production light level on coppicing and coppice timing were evaluated as means of accelerating the development of tree-form crapemyrtles. By the end of the growing season, ‘Fantasy’ and ‘Tuscarora’ coppiced in March and grown under 80% shade were 23 and 18% taller, respectively, than coppiced plants in full sun, but similar in height to plants under 50% shade. Coppiced Dynamite™ under 80% shade and coppiced ‘Carolina Beauty’ under 50% shade were 11 and 26% taller than coppiced plants in full sun, respectively, by the end of the growing season. Height of ‘Fantasy’ and ‘Tuscarora’, but not ‘Natchez’, at the end of the growing season decreased as coppicing was delayed from January to June. ‘Natchez’ coppiced in March were taller than plants coppiced in January or February and 68% taller than plants coppiced in June by the end of the growing season. Cross-sectional stem area of coppiced Dynamite™ and ‘Fantasy’ grown in full sun was greater than that of plants under 50 or 80% shade. Stem area of coppiced ‘Tuscarora’ under 50% shade was greater than that under 80% shade, but similar to that of coppiced plants in full sun. Stem area of coppiced ‘Carolina Beauty’ was greatest when grown in full sun, followed by growth under 50% shade, and least in plants grown under 80% shade. Stem area of ‘Fantasy’, ‘Natchez’, and ‘Tuscarora’ at the end of the growing season decreased linearly as coppicing was delayed from January to June. Visually, coppiced plants had straighter shoots, more uniform shoot diameters, and less branching off the main trunks than non-coppiced plants.

Abstract The effects of geographic location and production light level on vegetative growth and flowering were evaluated as a means of accelerating the development of tree-form crapemyrtles. By the end of the first year of the experiment, Dynamite™, ‘Muskogee’, ‘Natchez’, and ‘Tuscarora’ grown in Oregon were as much as 42, 51, 43, and 92% taller, respectively, than plants in Alabama, while plants generally had less trunk diameter in Oregon. ‘Muskogee’ and ‘Natchez’ in both locations and ‘Tuscarora’ in Alabama were generally taller when grown under 50% shade than plants in full sun, while height of Dynamite™ was not affected by production light level. Trunk diameter of ‘Natchez’ in both locations and of Dynamite™ in Alabama was less when plants were grown under shade, while trunk diameter of ‘Muskogee’ and ‘Tuscarora’ was not affected by production light level. Flowering of plants grown under shade in Alabama was delayed, while no plants in Oregon flowered the first year. In the second year of the experiment when all plants were grown in full sun, all cultivars continued to be taller in Oregon, while trunk diameter remained greater in Alabama. The height advantage gained from growing plants under shade the previous year was not evident in any cultivar by the end of the second year, while trunk diameter was similar for all cultivars previously grown in full sun and under 50% shade. There was no difference in flowering of plants in Alabama previously grown under 50% shade and in full sun, while 50 to 100% of the four cultivars in Oregon flowered with no obvious difference due to prior production light level.

The influence of mycorrhizal inoculum in combination with different phosphorus treatments on growth and flowering parameters of Ajania (Ajania pacifica (Nakai) Bremer et Humphries) plants was investigated in two growing seasons (2015 and 2016). Plants of the cultivar ‘Silver and Gold’ were transplanted into pots either with added mycorrhizal inoculum or without inoculum and assigned to four phosphorus treatments. Mycorrhizal colonization was assessed by evaluating the frequency of colonization, intensity of colonization and density of fungal structures (arbuscules, vesicles, coils and microsclerotia) in the roots. During the growing season, the content of plant available phosphorus in the soil was analyzed, and shoot length, number of shoots, number of inflorescences, number of flowers and flowering time were evaluated. Inoculated Ajania plants were successfully colonized with arbuscular mycorrhizal fungi and dark septate endophytic fungi. In the root segments, hyphae were mainly observed, as well as vesicles, coils, arbuscules and microsclerotia, but in lower density. The density of fungal structures did not differ among phosphorus treatments, but did differ between years, with a higher density of fungal structures in 2016. Mycorrhizal plants developed higher number of shoots in 2016, higher number of inflorescences, higher number of flowers, and they flowered longer compared to uninoculated plants.

Sugar palm is one of local plants spesies that may potential for reclamation program because can be planted under the stands of forest crops. Forest crops can be shade seedlings sugar palm from direct sunlight because the growth of sugar palm is relatively slow. Sugar palm can be useful even without cutting down the trees. Previously, sugar palm had been planted at PT Berau Coal and had produced fruit. The research was conducted at coal post-mining land of PT Bukit Asam, Tanjung Enim, South Sumatera. The research using combination of AMF and liming treatment is as follows, ie MaK0 (control), Mak1 (seedling with AMF without inoculation; liming 30 g plant-1), MiK0 (AMF indigenous seedling inoculation; without liming), MiK2 (AMF indigenous seedling inoculation, liming 60 g plant-1), MmK0 (AMF mycofer seedling inoculation; without liming), and MmK3 (AMF mycofer seedling inoculation, liming 120 g plant-1). The results showed that sugar palm could be grown in the coal post-mining land. The combination of AMF and liming treatment did not significant effect on observed variables of plant height, rachis length, diameter, leaves number, number of spore and root cholonization. Sugar palm seedlings that have been infected with AMF could be grown and provide a good growth response even without liming.Keywords : Arbuscular Mycorrhizal Fungi (AMF), marginal land, sugar palm

Abstract The production experiments were carried out based on the farm “Yaroslav the Wise” of the Starooskol district of the Belgorod region. The article studies the effect of the biological product Biogor KM during the pre-sowing treatment of grain in combination with double spraying of growing plants of spring durum wheat Dar Chernozemya 2. One of the experiments provides for grain processing with the period of “germination-ripening” of its wheat plants reduced by 8 days. The second variant, in addition to processing the grain, had two sprayings carried out during the growing season. The second experiment lasted even less by 12 days in comparison with the control variant. The article establishes the positive influence of the biological product on the formation of the productivity structure of spring durum wheat plants. Grain processing in combination with spraying during the growing season led to the formation of the best productivity structure: plant height was 39% higher, the number of spikelets was 41.8% higher, the number of spikelets was higher by 35.3%, and the grain weight per spike was 39.2%. versus the control variant. The yield in the experiment was in direct proportion to the method of application of the biological product and the conditions of the growing season. The largest increase in yield - 0.40 t / ha or 14.5% was obtained in the variant with grain processing in combination with double spraying of plants during the growing season, the average yield for the studied period was 3.14 t / ha and was maximum, indicators of economic and bioenergy efficiency was also the best.

Cuscus is an arboreal animal whose habitat is in the forest with the type of food consumed are fruits, leaf shoots, and agricultural plants. Animal manure can also be used as organic fertilizer for forage plants. This study aims to determine the growth response of Setaria grass (Setaria sphacelata) given a dose of cuscus manure fertilizer with banana and avocado consumption. The study was designed in a CRD with 3 treatments. The treatments were P0 = without fertilizer (100% soil), P1 = 40 g/polybag of cuscus manure with banana consumption, and P2 = 40 g/polybag of cuscus manure with avocado consumption. Planting is done by pols on polybags measuring 30 x 25 cm. The results showed that the highest plant height of Setaria grass was found in P2 with an average of 101.70, then P1 was 101.47 and P0 was 71.16 cm/week. The results were the same for the number of leaves and tillers, P2 showed significantly higher results (P<0.05), followed by P1 and control. The application of organic fertilizer of cuscus manure with the consumption of bananas and avocados can increase the growth of Setaria grass.

Abstract The growth response of young loblolly pine (Pinus taeda L.) to different amounts of competition control was studied in plantations of three ages in the Virginia Piedmont. Eight competition control treatments involved the removal of all, two-thirds, one-third, or none of the hardwoodstems either with or without herbaceous weed control. Results after three growing seasons showed a significant increase in pine diameter and volume growth with competition control. Treatments combining woody and herbaceous control resulted in better pine growth than the same treatments withoutherbaceous control, in the two youngest stands. The best response, obtained with the two-thirds woody plus herbaceous control treatment, resulted in: a 100% increase in volume growth over the check plots in seedlings treated at the beginning of their second growing season in the field; a 93% increase in one-year-old seedlings; and a 53% increase in the growth of seedlings treated before the third growing season.

The growth, development, and reproductive potential of several populations of organic arsenical-susceptible (S) and -resistant (R) common cocklebur biotypes were compared under noncompetitive field conditions. Plant height, leaf area, aboveground dry weights, and relative growth rate (RGR) were measured periodically during the growing season. Days to flowering, bur dry weight, and number of burs per plant were also recorded. Arsenical S- and R-biotypes were similar in all measured parameters of growth, development, and reproductive potential. Populations within each biotype varied occasionally in plant height, leaf area, aboveground dry weights, and reproductive potential.

This study examined the 10-year effects of a light (20% basal area removed) low thinning and urea fertilization (336 kg N/ha) on a 45-year-old Pinusbanksiana Lamb. stand. Thinning had no effect other than salvaging potential mortality, while fertilization resulted in an average annual gross volume growth response of about 2 m3 ha−1 year−1. Volume growth response to fertilization was greatest in the largest diameter trees, and continued until 10 years after treatment. Growth response did not begin until the second growing season after treatment. There were indications that fertilization had positive effects on form factor.

The Individual

Experiments were conducted to investigate the individual and interactive effects of nitrogen fertility, plant growth regulators and a fungicide on the growth response of Max spring wheat under Nova Scotia conditions. A lack of interactive effects of these three management factors was found, both under dry and sustained moist conditions. Increased nitrogen tended to produce lush growth and greater leaf disease. It also increased grain protein levels to acceptable milling levels. The rate of chlormequat chloride recommended for winter wheat (0.92 kg a.i. ha−1), applied at Zadoks growth stage (ZGS) 31, produced excessive reduction in plant height, tended to induce higher levels of leaf disease and depressed kernel size. Ethephon, applied at the rate recommended for winter wheat (0.42 kg a.i. ha−1) at ZGS 45, effectively reduced plant height without detrimental side effects. Propiconazole effectively reduced the incidence of powdery mildew, septoria and leaf rust and increased yields over unsprayed check plots. Timing of application affected the spectrum of disease controlled. Two applications of the fungicide (ZGS 32 and 45) gave excellent disease control and highest yields.Key words: Max, wheat (spring), chlormequat chloride, ethephon, propiconazole, nitrogen
