In addition to their value as cereal grains, wheat (Triticum aestivum L.) and triticale (× Triticosecale Wittmack) are important cool-season annual forages and cover crops. Yearling steer (Bos taurus) performance was compared in the spring following autumn establishment as for age cover crops after soybean [Glycine max (L.) Merr.] grain harvest. Replicated pastures (0.4 ha) were no-till seeded in three consecutive years into soybean stubble in autumn, fertilized, and grazed the following spring near Ithaca, Ne, USA. each pasture (n = 3) was continuously stocked in spring with four yearling steers (380 ± 38 kg) for 17, 32, and 28 d in 2005, 2006, and 2007, respectively. In 2005, average daily gain (ADG) for steers grazing triticale exceeded the ADG for wheat by 0.31 kghd-1d-1. In 2006, wheat ADG exceeded that for triticale by 0.12 kghd-1d-1. In 2007, steers grazing wheat lost weight, while steers grazing triticale gained 0.20 kghd-1d-1. Based on the 3-year average animal gains valued at $1.32 kg-1, mean net return ($ ha-1 yr-1) was $62.15 for triticale and $22.55 for wheat. Since these grazed cover crops provide ecosystem services in addition to forage, grazing could be viewed as a mechanism for recovering costs and adds additional value to the system. Based on this 3-year grazing trial, triticale was superior to wheat and likely will provide the most stable beef yearling performance across years with variable weather for the western Cornbelt USA.

Poverty is pervasive in the Swat Valley in northwestern Pakistan, and most people survive by farming small landholdings. However, many supplement their meager subsistence earnings by collecting and selling plant material for use in herbal medicine. This material is wild-harvested, but collectors seem not to fully appreciate the potential value of the plant material they collect nor the longterm impact their collection has on local plant populations. A model project supported by the International Food Policy Research Institute(IFPRI)persuaded small-scale farmers in four different villages to use some of their land for cultivating traditionally wild-harvested species of medicinal and aromatic plants(MAPs) with high market value. The farmers were provided seeds or rhizomes of five MAPs and asked to monitor their germination and growth on 25 m2 plots during a 12 month period. At the end of the study, growth and yield data from the four localities were compared and economic analyses conducted to determine the profitability of the species based on yields, prevailing market prices, and costs of production. Five of the cultivated species were subsequently marketed and their value evaluated:Sesamum indicum, Linum usitatissimum, Ocimum basilicum, Nigella sativa and Viola pilosa. The MAPs V. pilosa and O. basilicum were the most profitable,whereas Nigella sativa was the least profitable because of its low germination rate. The net income from all but Nigella was higher than that would have been earned by planting the same area with the predominant cereals or tomatoes. In addition to demonstrating the feasibility and financial benefits of cultivating MAPs as a cash crop, this model study identified a number of additional steps that would increase the benefits of MAPs cultivation in this area.A combination of specialized education, market infrastructure development and a small loans program would enable farmers to increase their agricultural income without damaging the area's pl

It was hanging on a rack ata secondhand clothing store in Northampton,Mass., crammed in with shoddy trench coats andan assortment of sad, woollen overcoats—a roseamong thorns. While the other coats drooped, this onelooked as if it were holding itself up. The thick,black wool of the double-breasted chesterfieldwas soft and unworn, as though it had been pre-served in mothballs for years in dear old
