Avocados in Precision Agriculture
At Pollen Systems, we are always excited to apply our PrecisionView approach to the crops we know and love. One fruit we keep returning to at work (and in our favorite recipes) is the beloved avocado. Adapted to rainforests by nature, avocados grow vigorously and will develop a dense canopy in a relatively short time. This growth habit is a challenge unique to cultivating avocados, as each tree ...

Italy - 2004 & 2005 CROPS - Melons - Case Study
PREAMBLE: Melons are members of the cucurbit family, which includes pumpkins, zucchini, cucumbers and squash, all of which have similar growth requirements. Melon quality is directly related to the sugar content of the fruit. High sugar content is achieved by avoiding all stress during the growing season. Stress comes from foliar diseases, insect pests, weeds, poor nutrition, and excesses or ...

Soft Fruits Early Spring Fertilizers
Early-spring maintenance of soft fruit trees is important to start the growing season correctly and to prepare the trees for healthy, vigorous growth and an abundant harvest. Without early-spring fertilizing, fruit trees may suffer unnecessarily stunted or weak growth and damage. Here are the perfect tips from Oligro to start early spring fertilizing. Fertilizers: 16-8-24 Fertilizer Boroni ...

How to Prevent Fertilizer Caking in Compound Fertilizer Production
The longer the compound fertilizer is placed, the easier it will cake. On the contrary, the shorter the storage time, the more difficult it will cake. In order to avoid caking of compound fertilizer, what problems should we pay attention to in NPK fertilizer production line? Tianci fertilizer machine manufacturer will give you a detailed introduction, hoping to help you: A. Reasonable selection ...

Root and foliar uptake, translocation and distribution of [14C]fluoranthene in pea plants
Uptake of 14C‐labelled fluoranthene ([14C]FLT) via both roots and leaves of Pisum sativum seedlings and distribution of [14C] in plants by both acropetal and basipetal transport was evaluated. The highest [14C] level was found in root base (≈270 × 104 dpm/g dw) and the lowest level in the stem apex (<2 × 104 dpm/g dw) after just 2 hours of root exposure. For foliar uptake, the highest level of ...

Molecular mapping of wheat leaf rust resistance gene Lr42
Leaf rust, caused by Puccinia triticina Eriks., is an important foliar disease of wheat (Triticum aestivum L.) worldwide. Leaf rust resistance gene Lr42 from Aegilops tauschii Coss. has been used as a source of rust resistance in breeding programs. To identify molecular markers closely linked to Lr42, a segregating population of near-isogenic lines contrasting for the presence of Lr42 was ...

Validation of molecular markers associated with net blotch resistance and their utilization in barley breeding
With the advancement of molecular marker technology and computer software, mapping quantitative trait loci (QTL) for complex traits in agricultural crops is frequent; however, exploitation of these QTL in practical breeding programs is limited. Here we report the validation of molecular markers linked to net blotch resistance QTL and their utilization in a barley (Hordeum vulgare L.) breeding ...

Inheritance of resistance to stripe rust in three lines of soft red winter wheat
Since 2000, stripe rust, caused by Puccinia striiformis Westend. f. sp. tritici Eriks., has been the most important foliar disease of wheat in the eastern United States. Three lines of soft red winter wheat, ‘McCormick’, VA96W-270, and a variant of VA96W-270 (VA96W-270V), were resistant to the stripe rust population first described in the United States in 2000. The objective of this study was to ...

Effect of fungicide on soybean growth and yield
In response to rising input costs and narrowing profit margins, soybean [Glycine max (L.) Merr.] producers are continually looking for ways to increase soybean yield. One approach being promoted is the use of foliar fungicides, for both foliar pathogen control and nonfungicidal plant physiological effects. The objective of this field experiment was to evaluate a strobilurin and a triazole alone ...

Foliar Iron Fertilization of Peach (Prunus persica (L.) Batsch): Effects of Iron Compounds, Surfactants and Other Adjuvants
Abstract Experiments to assess the capability of different combinations of iron (Fe) compounds and adjuvants to provide Fe via foliar application to Fe-deficient plants have been carried out. A total of 80 formulations containing (1) one of five Fe-compounds [FeSO4·7H2O, Fe(III)-citrate, Fe(III)-Ethylenediaminetetraacetic acid (EDTA), Fe(III)-Diethylenetriamine pentaacetic acid (DTPA), ...

Lettuce cationic nutrition and yield, and soil chemical characteristics as affected by vanadium application to leaves or soils
Lettuce plants (Lactuca sativa, L., cv. "trocadero") were grown in pots filled with an Alfisol Udalf or an Andisol Udand soil, under greenhouse conditions. Treatments consisted of adding vanadium to soils (0, 100, 250, 500 and 10001mg1kg1 or as foliar sprays (0, 10, 25, 50, and 1001mg111. Soil chemical characteristics, the cationic nutrition of lettuce and their yields were assessed. No ...
