This year. the show pronúses to be bigger and better than ever. Special events have been scheduled and quallty souvenirs have been commissioned to commemorate the 75th Farm Show. We are very proud to showcase our number one industry in an exposition of such magnitude. With 14 acres of exhibits under roof, the show is a salute to the hard worlt and dedication of Pennsylvania's farm families, foocl processors and agribusinesses. lt is difficult to estímate the extraordinary contributions made by the Farm Show during its first 74 years.

Texas Effects of Harvest Date on Yield, Grade, and Gross Return from Peanuts in Texas I~~~ O.D. Smith, C.E. Simpson, E.R. Howard, S.M. Aquirre, and G.B. Parker' Marketing Trends and Opportunities Summary Five ha.rvests were madeoffour peanut varieties 1n irrigated field trails near Stephenville and Bryan, Texas 10 1984 and 1985. Yields and grades were detennined for each variety and harve&t, and the gross ,•alues per acre were calculated usingthe 1988 t.;SDA loan rates. Wecds, d1seases, and insects were controlled. In general, ali entries increased in yield, grade, and gross value per acre as harvest was de· layed until 140 days alter planting. Averaged over the 2 years, Langley was the only entry to show decrease in gross valuc from delaying digging to the last digging date, and that decrease was not significant (P=.05). The average weekly increase in gross value for the four varieties and five harvests was $50 and $146 per acre for the Bryan and Stephenville tests, Tespectively. Premature diggingcan cause si.e• nificant reduction 1n income from peanuts. lntroduction Toe detennination of optimal harvest date is an annual arbitrary decision required of ali peanut fanners. Severa! proccdures for detennining the degree ofmaturation have been described (1,2,3,4,5). Examinallon of interna! hull (pericarp) color (1,3), and seed color and plumpness are among the oldest ofthe methoda and are quite effective for most varietles in most environments. However, sorne varieties do notcolor asmuch asothers, and under sorne poorly defined conditions coloration does not de\'elop strongly in the shell, although the peanuta grade high.

Cotlege Station, Tex• l<EVWOROS MatvratiotV g,OW1h duratiOn/ grouodnUI seed-hull ratio method (4) works reasonably well within a variety ifthegrower knows the approximate proportion by weight of mature pods that should be seed under the cultural system and environment in which the pea nu ts a re grown. Widespread promotion has been given to the hull-scrape method (5) which seems to be effcctive, especially for Florunner in the southeastern U.S. For ali ofthcse methods, effective random sampling of the lield is required. If the sample does not adequately represent the peanut lield under consideration, the maturity determinalion is meaningless. Onen, because ofrush and other factors, digging is begun largely because ofthe number of days from planting. The effect of harvest date on yield, grade, and value per acre waa studied on four peanut varieties in Texas in 1984 and 1985. Multiple 30 feet-of-row plot& ofrunner (Florunner, Tamrun 88, and Langley) and Spaniah (Tamnut 74) varieties were planted at both Stephenville and Bryan to facilitate five harvest dates at each location. The seeding ratea approd• mated 80 lbs/acre (4.5 seed/n for the runner entries and 6 seed/ft for the Spanish) with four replicationa of each digging date at each test site. The dates of plantingwere May 10 and May 13 atBryan, and May 10 and June 10 at Stephenville, in 1984 and 1985, respectively. The soil at Bryan was a Patilo loamy fine sand, and al Stephenville a Windthorst fine sandy 10am. Treílan (triíluralin) (onc pVac) at Stephenville, and Treílan (0.9 pVac) plus Dual (mctalachlor) (1.5 pVac) at Bryan were incorporated before planting. Leafspot was controlled with approximetely biweekly applications ofBra"o lchlorothalonil). Terrachlor (pentachloronitrobenzene) and gypsum were applied at. Dryan I<> reduce soilbome diseases. Gypsum was applied al Stephenville I<> aid digging, Water was applied by overhead sprinklera to supplement rainfall.

R. Heineman and Frank PR-4686 Dainello• L. A, Rodriguc,-dcl-Bo,quc ami J W, Smilh, Jr, t SUMMARY INTRODUCTION Spinach varieties and experimental lines were screened for tolerance to white rust disease as indted by Albugo occidentalis in Uvalde nurseries from 1985 through 1989. Fall Green, Green Valley 11, Ozarka ll and Sassy, consistently displayed the least severe reaction to white rust infection. Coho, Ambassador, Triade and Chinook 11 also possessed acceptable field tolerance to this disease. Severa! experimental lines showing potential for white rust tolerance lines are: ACX 5044, XPH 1952 and 4CX-124. Of these experimental lines ACX 5044 was the only smooth leaf processing type. In these evaluations a greater number of savoy fresh market types than smooth leaf processing types exhibited field tolerance to white rust. One of the major production problerns faced by the Winter Carden spinach industr)' continues to be the white rust disease. To facilitate identification of tolerant germplasm to this disease, a white rust tolerance screening nursery was established at Uvalde in the fall of 1980. Since then 25-30 entries have been screened annually for tolerance to this disease No smooth leaf processing types and only three savoy fresh market types were identified in previous nurseries as having field tolerance to white rust: Green Valley II, Ozarka II and Coho (2,3). Consequently, continuous evaluation of tolerance to white rust in new varieties and experimental lines is needed. This report summarizes results from screening nurseries conducted for 5 years-1985-1989. 1 KEYWORDS: Albugo occidentalis, Spinaceae oleracea, tolerance 'Respectively, rese.:irch ass,stant and former Agricultura!

Black sheath rot was thc name gfven by Tullís (3) and is the name most promincnt in the literature. Tbc disease was first found in the Unfted States in 1924 in Adcansas and since 1928 has been rcpeatedly found on ria: in the vicilllty of Swngan, Artansas (2). Introduction Thefirst rcportafthe ctilease in Texaswas in 1947 (3) in a ficld neax Hocklcy. Black sheath rot is c:haracterized iarly by a black, nondcscript lcsion on tbe Jeaf sheath, usually below the water line.

Lavy Rapid, Cost-Effective LAIMeasurement System Toe LAI-2000 Plant Canopy Analyzer provides a rapid, non-destructive, non-contact method to measure Leaf Area Index (LAI). Precise monitoring of canopy growth or reduction due to insect infestation, disease, air pollution, or herbicide injury is possible since canopies can be repeatedly measured throughout their life cycles. The LAI-2000 determines LAI by using a fisheye optical sensor to measure canopy light interception, from which LAI is calculated using a model of radiative transfer in vegetative canopies. LAI measurements with the LAl-2000 take only a small fraction of the time required to directly measure LAI with an area meter. The cost savings throughout a research project can be substantial.
