Ornamental bulbous crops emergence and yield can be improved by its emergence from soil. The response of Caladium to different planting depths and dates was investigated at Ornamental Horticulture Nursery, Department of Horticulture, The University of Agriculture, Peshawar during the year 2008. Randomized Complete Block Design in a split plot arrangement was used repeated three times. Sowing dates (30th March, 15th April and 30th April) were allotted to main plots whereas planting depths (2.5 cm, 5 cm, 7.5 cm and 10 cm) were kept in sub plots. Findings revealed that Caladium tubers sown on 30t

Inappropriate agronomic practices, such as earthing up and inflorescence removal, are responsible for the great discrepancy between the potential and achievable yields of potatoes in Ethiopia. To assess the effects of the combination on the tuber yield and yield components of potato, a factorial combination of four earthing up rounds (without, one, two, and three rounds) and three inflorescence removal levels (without removal, bud removal, and flower removal) was used in a randomized complete block design with three replications.

The ability to freeze cardiac motion in each individual image yields the notion of temporal resolution (scanner rotation time, number of sources, multisegment reconstruction, and motion correction algorithms). The aim of minimizing the number of involved cardiac cycles is translated into detector coverage (physical collimation, number of slices, slice width).

Given that the maximum stress of the equivalent solid plate generally occurs adjacent to the solid tubesheet, a novel finite element modeling methodology is proposed in this paper. A two part proces
