Controller Area Network Based Distributed Control For Autonomous Vehicles, Matthew J. Darr, Timothy S. Stombaugh, Scott A. Shearer

Biosystems and Agricultural Engineering Faculty Publications

The goal of this project was to evaluate the potential of a controller area network (CAN bus) to be used as the communication network for a distributed control system on an autonomous agricultural vehicle. The prototype system utilized microcontroller-driven nodes to act as control points along a CAN bus. Messages were transferred to the steering, transmission, and hitch control nodes via a task computer. The task computer utilized global positioning system data to generate appropriate control commands. Laboratory and field testing demonstrated that each of the control nodes could function simultaneously over the CAN bus. Results showed that the task …

An excavated tank is an earth structure on near level land used to impound water, in which a percentage of the storage capacity is below ground level. It includes similar structures constructed on sloping land, referred to as 'hillside dams'. These are specific types of the group of water-impounding structures known as 'farm dams'.

How To Calculate Machinery Ownership And Operating Costs, Burton Pflueger

SDSU Extension Circulars

Machinery ownership and operating costs represent a substantial portion of total production expenses for South Dakota producers. Production practices today require increasingly specialized machinery and equipment and producers have to give more attention to the economics of their machinery investment alternatives. Large amounts of capital are invested in owning and operating farm machinery. Producers need to take time to manage their machinery investment to insure that they are achieving the desired return and efficiency. Machinery costs make up a significant part of the fixed and variable costs of any farm operation. However, they are sometimes difficult to calculate, particularly for …

Code Of Practice For The Use Of Agricultural And Veterinary Chemicals In Western Australia, Peter Rutherford

Bulletins 4000 -

Agricultural and veterinary chemicals are a critically important input to modern farming systems. There is, however an increasing responsibility on the spray operator and his supervisor to use them with utmost safety. An effective way of providing the “rules” of safe chemical use is through a Code of Practice, the concept of which arose because of the increase in new and emerging agricultural industries and their impact on traditional uses of agricultural chemicals.

Turkish Journal of Agriculture and Forestry

This study was carried out to determine the infection rates of 9 Paecilomyces fumosoroseus isolates and 1 Paecilomyces lilacinus isolate on the glasshouse whitefly (GWF), Trialeurodes vaporariorum. Furthermore, the infection progress of P. fumosoroseus was observed on the insect using light and scanning electron microscopes. Bioassays were carried out on second instar nymphs by the application of a spore suspension of each isolate. The mortality data were recorded 3 and 6 days after the application. The effect of Paecilomyces isolates increased as the incubation time was extended. Seven isolates caused significant mortality to the GWF nymphs. The most virulent isolates, …

Temperature Dependent Life History Traits Of Brevicoryne Brassicae (L.) (Hom., Aphididae) On White Cabbage, Serdar Satar, Ulrich Kersting, M. Rifat Ulusoy

Turkish Journal of Agriculture and Forestry

The developmental time, survival rate and reproduction of the cabbage aphid, Brevicoryne brassicae (L.) (Homoptera, Aphididae), were evaluated on detached cabbage leaves (Brassicae oleracea var. capitata) at four constant and two alternating temperatures (15, 20, 25, 30, 25/30 and 30/35 ºC). Developmental periods of immature stages ranged from 12.5 days at 15 ºC to 6.0 days at 25/30 ºC. The alternating temperature of 30/35 ºC was lethal to immature stages of B. brassicae. The lower developmental threshold for the cabbage aphid was estimated at 4.0 ºC and it required 142.9 degree-days for a first instar to become an adult. The …

Turkish Journal of Agriculture and Forestry

This study was conducted to determine the effects of early season drought stress on some plant characteristics of 9 sugar beet genotypes in the Khorasan Agricultural and Natural Resource Research Station, NE Iran. The experimental design was a split plot with a randomized complete block arrangement. Leaf area index, leaf dry weight, shoot dry weight and root dry weight decreased under drought stress compared to non-stress conditions. The decrease was more pronounced as the rate of stress increased. Leaf area index was more affected by water stress than was leaf weight (losses of leaf area indices were 14.1% and 66.6% …

Functional Response Of Two Coccinellid Predators, Scymnus Levaillanti And Cycloneda Sanguinea, To The Cotton Aphid, Aphis Gossypii, Ali̇ Arda Işikber

Turkish Journal of Agriculture and Forestry

Functional responses of 2 female coccinellid predators, Scymnus levaillanti and Cycloneda sanguinea, to the cotton aphid, Aphis gossypii, at various temperatures were studied under laboratory conditions. Both coccinellid species showed different functional responses to the cotton aphid. The larger species, C. sanguinea, was seen to eat more aphids than the smaller species, S. levaillanti, at each temperature, due to its greater voracity. The female adults of both coccinellid species feed maximally during the first 3 h and therefore, the increase in fresh weight gain and number of aphids killed by both coccinellid species are much higher during the first 3 …

Simulation Of A Feedback Control Technique Through Irrigation Canal Junctions, Ömer Faruk Durdu

Turkish Journal of Agriculture and Forestry

A linear quadratic controller based algorithm was developed for simulating the dynamics of a single-reach irrigation canal with a channel junction. Using the concepts of feedback control theory, an expression for an upstream gate opening of an irrigation canal reach with a channel junction operated based upon a constant-level control was obtained. In the derivation, the canal reach between 2 gates was divided into 5 nodes, and the finite difference forms of the continuity and momentum equations were written for each node. The Taylor series was applied to linearize the equations around equilibrium conditions. At the third node of the …

Boron concentrations of plants sampled from barley cultivated areas of the CATZs region at 189 sites during springs 1996 and 1997 were determined. Boron toxicity symptoms were observed mainly in small areas near Konya-Çumra, Ankara-Gölbaşı, Yenikent and Yozgat-Yerköy and between the provinces of Konya and Aksaray. While boron toxicity symptoms were not observed in 79% of samples, 15% and 6% of samples showed light and medium-severe toxicity symptoms, respectively. As boron toxicity …

Comparison Of Methodologies For The Identification Of Aroma Compounds In Strawberry, Ebru Kafkas, Sali̇h Kafkas, Margery Koch-Dean, Wilfried Schwab, Olga Larkov, Noa Lavid, Einat Bar, Uzi Ravid, Efraim Lewinsohn

Turkish Journal of Agriculture and Forestry

Three strawberry (Fragaria x ananassa. Duch.) varieties commercially grown in Israel (Tamar, Yael and Malach) were studied for their volatile compositions. Two techniques were compared: headspace solid phase micro extraction (HS-SPME) and liquid-liquid extraction (organic solvent: tert-butyl methyl ether) by gas chromatography/mass spectrometry (GC/MS). The influences of techniques on the volatile compounds were tested by comparing the volatiles determined in the 3 varieties. Malach, the most aromatic variety, accumulates high levels of furanones and esters compared to the other varieties. Differences in the aroma profiles obtained by utiliszing different techniques were noted. HS-SPME was more suitable for the determination of …

Effects Of Reduced Tillage And Planting Systems On Seed Cotton Yield And Quality, İbrahi̇m Yalçin, Aydin Ünay, Rauf Uçucu

Turkish Journal of Agriculture and Forestry

There is increasing scientific and practical interest in the importance of reduced tillage systems for increasing yield, and obtaining it more economically, in cotton production. Reduced tillage systems which involve lesser field applications have several advantages when compared to conventional systems. Field trials were conducted over 2 years. The aim was to establish the greatest applicability of reduced tillage systems. The 4 types of tillage compared were conventional, precision, strip and ridge tillage. In each of these plots, seeds were planted in 8 rows. A mechanical seed drill was used in 4 rows of each plot at a seed rate …

Using Real Options Theory To Analyze The Impacts Of Urban Development On Farm Real Estate Markets, Tamer Işgin, D. Lynn Forster

Turkish Journal of Agriculture and Forestry

This paper assesses the real option values of farmland using data from Ohio, USA. The option value of delaying the sale of a farm property was measured using an emerging, relatively new theory namely, the theory of real options pricing. As opposed to standard corporate finance theory, this new theory incorporates both the uncertainty about the future net benefits of a selling decision and the irreversibility of this action taken. Results from this option value calculation show that the vast majority of real call option values calculated for this sample are greater than zero, suggesting that deferring the decision to …

Determining Combining Ability In Sunflower (Helianthus Annuus L.), Yalçin Kaya

Turkish Journal of Agriculture and Forestry

The experiments, involving 25 sunflower hybrids, were conducted in 3 locations in 2000 and 2001. These hybrids were evaluated for 4 important yield components (seed and oil yields, oil content and hull ratio) by combining ability. The experimental design was a randomized complete block design with 3 replications. Based on specific combining ability (SCA) analysis, the hybrid 2453-A x 2644-R was determined as the best hybrid in the experiment. The female lines 2453-A and 0704-A and the male lines R-1001 and 2644-R had higher seed and oil yield performances in this research. However, the 2644-R and 2280-R restorer and HA89-A …

Turkish Journal of Agriculture and Forestry

Cereals are sensitive to micronutrient problems. Central Anatolian soils show great variation with respect to both deficiency and toxicity of boron (B). Hence, screening of major wheat cultivars grown in the region with respect to their sensitivity to B is of great importance for the area. Six durum (Triticum durum L. cvs. Kızıltan-91, Ç-1252, Selçuklu-97, Kunduru-1149, Yılmaz-98 and Çakmak-79) and 6 bread (Triticum aestivum L. cvs., Gün-91, Kınacı-97, Göksu-99, Türkmen, Bezostaja-1 and Sultan-95) wheat cultivars were studied in field experiments for their responses to B application when grown in soils low in extractable B (0.19 mg B kg^{-1}) during the …
