High density light detection and ranging (LIDAR) imaging has been shown to be able to define yield stability areas of a field for multi-cropping. Since LIDAR imaging is expensive and not widely available, it was hypothesized thatmedium resolution GPS elevation datawhich is commonly collectedwith variable rate technology (VRT) controllers andcropyieldmonitors couldbeused in lieuof LIDAR imaging....

Vegetables have a relatively high nitrogen requirement and at times growers apply too much fertilizer-N that contributes to ground and surface water pollution. Fertilization can be made more efficient by plant analysis. Plant tissue (petiole) nitrate testing is a way of monitoring the nitrogen condition of the crop during the growing season. This is an especially useful method as the petiole is...

It is conservatively estimated by prominent tomato growers and shippers in Texas that annually more than 15 per cent. of the Texas tomato crop is lost due to a condition commonly known as "Tomato Pops," or "Tomato Puffs." The trouble is serious in all the Southern States. At present the cause or causes of this abnormal condition are unknown, presenting a challenge to the Experiment Station work...

The above background information indicates that -citrus, as the most important tree fruit crop, amply justifies international training programs such as this short course on irrigation. Your Florida hosts are to be commended on their vision and desire to serve citrus growers everywhere in arranging these sessions-especially considering that citrus in Florida was largely unirrigated until recentl...

The yield of rainfed crops is commonly limited by the availability of soil water during the summer growing season. Channels produced by cover crop roots in fall/winter when soils are relatively moist may facilitate the penetration of compacted soils by subsequent crop roots in summer when soils are relatively dry and hard. Our objective was to determine the effects of fall cover crops on maize ...

P eople have harvested mushrooms from the wild for thousands of years for food and medicines. Of the estimated 1.5 million species of fungi, about 10,000 produce the fruiting bodies we call mushrooms. While commercial harvesting of wild mushrooms continues today, most of the world’s supply comes from commercial mushroom growers. The Chinese first cultivated shiitake (Lentinula edodes) mushrooms...

Crop area estimation is a key element in crop production forecasting and estimation. Satellite imagery can provide valuable information for stratification purposes and can be used as a source of proxy variables for aposteriori correction of area estimates. In this regard, efficiency of crop area estimation using satellite imagery depends on the accuracy of crop classification. In this paper, we...

This research was conducted to study of the essential oil content, some morphological parameters, crop evapotranspiration (ETc) and crop coefficient (Kc) of Summer Savory (Satureja hortensis L.) in the west of Iran (Khorramabad region) in 2017. Weighing Lysimeters (25 cm diameter and 30 cm height) were used to measure important morphological parameters, t...
