The most damaging insect pests are those that attack the pods and result in either damage or contamination of the processed product. The European corn borer (ECB) and to a lesser extent the corn earworm (CEW) are the major pod feeding pests with damage primarily from 2 generation ECB and late flights of CEW in August/September. Damage from both species occurs from flowering to harvest, creating...

The coordination of the timing of flowering with seasonal and development cues is a critical life-history trait that has been shaped by evolution to maximize reproductive success. Decades of studying many plant species have revealed several of the fascinating systems that plants have evolved to control flowering time: such as the perception of day length in leaves, which leads to the production...

dehghan (ksc 400) is an early-medium maturity grain maize hybrid that has been developed from a cross between two inbred lines (ke72012/12×k1263/1). this cross was carried out in 1997, for the first time. the characteristics of dehghan hybrid were studied in different trials (preliminary, semi final, final and on farm trials) in several locations during 1997 to 2005. the mean grain yield of the...

In Dagestan, there are local varieties of tomatoes that have valuable economic and biological characteristics: good yield, excellent taste qualities fruits, high technological qualities, etc. this regard, the Apple variety is interest. However, uneven represents a motley population. There deviations – low-yielding, weak-leaved, strongly exposed to sunburn, with different fruit shapes from round...

Alfalfa (Medicago sativa L.) proteins ingested by dairy cows typically degrade at rapid rates and exhibit extensive ruminal degradability. Although the effects of conservation method (hay or silage) on these characteristics have been evaluated extensively, agronomic factors, such as harvest timing, have not. Our objective was to quantify rumen degradable protein (RDP) for ‘Affi nity’ alfalfa ha...

Estimates of range-wide abundance, harvest, and harvest rate are fundamental for sound inferences about the role of exploitation in the dynamics of free-ranging wildlife populations, but reliability of existing survey methods for abundance estimation is rarely assessed using alternative approaches. North American mallard populations have been surveyed each spring since 1955 using internationall...

The objective of this study was to evaluate the effects of ensiling time and exogenous protease addition on soluble CP (% of CP), ammonia-N (% of N), and ruminal in vitro starch digestibility (ivSD) of whole-plant corn silage (WPCS) from 3 hybrids, 2 maturities, and 2 chop lengths. Samples from 3 nonisogenic hybrids [brown midrib containing the bm3 gene mutation (BM3), dual-purpose (DP), or flo...

Perinatal health was investigated by linkage with the Medical Birth Registry of Norway for 192,417 births that took place between 1967 and 1991 among parents identified as farm holders in Norwegian agricultural censuses in 1969-1989. In a comparison with 61,351 births to nonfarmers in agricultural municipalities, farmers' births had an advantageous distribution of gestational ages and birth wei...

We evaluated the impact of commercial moss harvest on the development of an understory epiphyte community in the Pacific Northwest by characterizing natural development stages using data from both a long-term regrowth study and demographic sampling. First, experimentally stripped 1 m long cylindrats on 46 shrub stems in the Oregon Coast Range were monitored for species composition and abundance...

We develop a tractable continuum player timing game that subsumes wars of attrition and pre-emption games, in which greed and fear relax the last and first mover advantages. Payoffs are continuous and single-peaked functions of the stopping time and quantile. Time captures the payoff-relevant fundamental, as payoffs “ripen”, peak at a “harvest time”, and then “rot”. Whenever payoffs are nonmono...
