The objective of this study was to determine the effect of forcing summer asparagus (May to October) and age at first harvest after transplanting on yield and quality. Ten-week-old `UC 157 F1' asparagus seedlings were field-planted on Sept. 1986 and forced to emerge from 1988 to 1992 by mowing fern in separate replicated plots in May, June, July, August, September, or October. Forcing treatments were not spring-harvested. Forced yields were compared to normal spring harvests (emerging from January to April). Harvesting began for the first time ≈18 or 30 months after transplanting. Spring 1988 yields were greatest of all, but declined yearly for 5 years. Summer forcing in either July or August maintained acceptable yields through 1992. The warmer climate during summer forcing caused most plants to reach the prescribed cutting pressure (eight spears per plant) within a standard 6-week harvest season. Cooler temperatures during spring harvest seasons slowed spear emergence and prevented the plants from reaching prescribed cutting pressure. Forcing in May and June was too stressful to plant recovery after the harvest season by reducing fern regrowth and increasing plant death. Cooler temperatures during October forcing inhibited spear emergence. Forcing in September yielded less than forcing in July and August, but September asparagus would command higher market prices. There was no advantage at any harvest time to delay first harvests from 18 to 30 months after transplanting. Forcing in July through September has potential as an alternative enterprise in coastal South Carolina.

Successful Establishment

An analysis for the value of carbon forestry needs to be provided for the successful establishment of the carbon offset market in Korea. We present an optimal management strategy for a forest owner who participates in the offset market. Given a stochastic process of the timber price following a geometric Brownian motion, the profit maximization problem of the forest owner is solved. The model finds an optimal harvest time in the presence of the carbon and timber revenues with opposing time effects. Sensitivity analysis is performed with respect to the volatility rate of the timber price and the discount rate. The presented model is applied to the study of the Korean larch case to identify the threshold timber price above which it is optimal to harvest trees.

Field experiments with three barley (Hordeum vulgare L.) cultivars, Olli, Bonanza and Klages, were conducted for 3 yr at Beaverlodge, Alberta to determine the effect of harvest time and drying method on yield and quality. Plots were harvested at 5% kernel moisture content (KMC) intervals in the range of 45–15% and dried in the windrow or artificially dried. Yield, test weight, 1000-kernel weight, germination percent, protein content, phosphorous content and commercial grade were determined. Protein and phosphorous content were unaffected by the treatments. Windrowing at 40% KMC or less had little effect on yield or quality characteristics while threshing and artificially drying barley above 20% KMC reduced test weight and germination. Windrowing reduced yields of Olli and Klages barley by up to 19% compared to direct combining. Most treatments received feed grades, but the crop was most likely to meet Canada Western grades when windrowed at 30% KMC or less under favourable harvest conditions.Key words: Hordeum vulgare L., kernel moisture content, yield, quality
