Predicting field performance of five irrigated tree species using seedling quality assessment in Burkina Faso, West Africa

Five exotic tree species (Acacia angustissima (Mil.) Kuntze, Acacia mangium Wild, Gliricidia sepium (Jacq.) Alp., Leucaena hybrid (LxL), and Leucaena leucocephala (Lam.) de Wit) were investigated to determine whether parameters of nursery seedling stock quality could be used to predict their field performance in a plantation irrigated with treated waste-water to produce fodder and wood. Plants were grown in the nursery in two contrasting rooting substrates (ordinary nursery soil and sand), predicted to have different effects on resource allocation. Three categories of morphological indicators were measured, i.e. plant dimensions (height, diameter, root length), plant weights (shoot, root and whole plant weights) and indices (sturdiness quotient ‘SQ’, shoot:root dry weight ratio ‘SRR’ and Dickson’s quality index ‘DQI’). In the nursery, all species performed better in the ordinary nursery soil for all growth parameters except root length. Thus ordinary nursery substrate appeared superior to sand in terms of plant quality. However, a follow up at plantation phase revealed that only some morphological attributes or ratios were suitable to predict field performance for the five tested species in irrigated plantation. In addition, the effect of the substrate observed at the nursery stage had disappeared 12 months after out planting due to the availability of water and nutrients provided by the treated waste water used for the irrigation. The results showed that root collar diameter and DQI appeared to be the most appropriate indicators to predict the outplanting performance of the five tested species in a short-rotation irrigated plantation in semi-arid Burkina Faso. The former measure is simpler and non-destructive

The operational effectiveness of the forest nursery sector in Leyte, The Philippines

Current programs and policies on forest management in the Philippines are biased towards the promotion of small-scale forestry. However, the scaling-up of smallholder forestry is hampered by the limited availability of planting materials and the low quality of planting stock. A study of the operational effectiveness of the forest nursery sector in the province of Leyte reveals that the operation of the nursery industry is not well-organized. The support provided by assisting agencies failed to promote the sustainability of smallholder nurseries. While a decentralized nursery management is widely perceived as the best alternative for reaching smallholders with planting stock, transferring the seedling production to smallholder nurseries needs strong collaboration with and support from the government nursery group. It is imperative for the government nursery group to refine its production objectives, operation schemes, types of assistance extended to smallholders and the means of extending the support to make it attuned to the needs and constraints of the smallholder nursery group

The apple leaf-hopper

The retardation of growth of apple stock in Iowa nurseries, caused by the apple leaf-hopper, has been very common from year to year, and has resulted occasionally in extensive losses to young nursery stock. The large nurseries at Charles City, Des Moines, and Shenandoah, as well as many others in the state, are more or less troubled with this insect every year. Although this leaf-hopper attacks many kinds of plants and trees, the injury is most serious on young apple trees, especially when planted in the nursery row, and it is as a nursery pest that this insect is considered in this bulletin. During the past year the apple leaf-hopper was more abundant than common, and as a result a large amount of nursery stock was stunted seriously. Aside from apple trees this insect frequently attacks birch and Norway maple trees, and even potatoes. The pest is known to science as Empoasca mail

Fertilizer trials for bareroot nurseries in North America

In North America, most tree nursery nutrition publications during the past two decades involved either container-grown stock or stock grown in greenhouses. In contrast, most bareroot nursery fertility trials in North America were published during the last century.  As a result, some bareroot fertilization recommendations have remained the same since 1980 and some practices continue to be based on myths and assumptions. The bareroot nursery industry in the USA might benefit if the next generation of graduate students will consider testing old and new theories about nursery fertilization.  Hopefully, they will discover new facts so that future fertilization regimes will be based on science. This paper provides various fertilizer trials that should be established in bareroot nurseries

Nursery location and potassium enrichment in Aleppo pine stock 1. Effect on nursery culture, growth, allometry and seedling quality

There is a need for a better understanding of the primary role of macronutrients in Aleppo pine stock quality and for producing larger nutrient-loaded stock, which may be challenging for inland nurseries. The influence of nursery location and fertilization on nursery culture, growth, allometry and seedling quality of Aleppo pine was studied in seedlings cultivated over the 2006 growing year. Fertilization treatments considered how a K enrichment performed over common programs currently being practiced and divided into three levels of K/N ratio: 0.63-0.89 (normal), 1.81-1.89 (high), and 2.25-2.53 (very high). Results showed that fertilization had a minor effect on seedling growth and allometry in comparison with location, which was the governing factor. However, fertilizing treatments significantly affected final seedling attributes, which has its origin on the early treatment differences that were kept up to the end of culture. Higher nutrient supply treatments produced the highest nutrient concentration in seedlings but they were associated with lower fertilization efficiencies. Fertilizer efficiency was approximately twofold in the coastal nursery for the three macronutrients, although concentration was higher in the inland nursery due to lower seedling growth. It is concluded that warmer regions are more suitable for producing large stock more efficiently. © Institute of Chartered Foresters, 2011.
