the experiment was conducted under Syrian coastal conditions to investigate (Vicia
fabaL.), the effect of boron and zinc foliar fertilization on faba bean,either individually or
in combination, by increased rates (0, 0.25, 0.50, 0.75, and 1 kg boro
n / has boric acid, and
zinc at a rate of 0, 0.375, 0.750, 1.125, and 1.5 kg / ha as zinc sulfate). where fababeans
were plantedin plastic pots(15L) in )2013/11/10(and )2014/11/10(.The soil in pots has high
content of calcium carbonate, low boron and zinc content, with pH slightly basic
(representative of the region's soils).
Half boron and zinc fertilizer rates were sprayed after 33 days of germination and the
other half ,after 65 days of germination. The results showed significant responses in all
studied parameters (number of branches,number of pods / plant, weight of 100 seeds, and
seed yield (Kg. / ha) on faba bean plant, as a result of foliar fertilization by boron and zinc.
Fababeans response to boron is higher than to zinc fertilization in all studied
indicators. However,the treatmentB75Zn75(0.75 kg boric acid and 1.125kg of zinc sulfate)
is the best, as compared to others. Also, the driedseeds yield was increased by about
17.66%.
Fifty clones of local seeded apricot (Klabi). Prunus armeniaca L. were
classified AL-Goutta orchard during ١٩٩٦–٢٠٠٠ . These clones were analyzed
in terms of physical and chemical characteristics with the objective of selecting
individual clones (
For dried apricot sheets) that meet the standard
specifications.
Choosing of sprinkler trajectory angle and estimation of its
changing is an important factor in sprinkling irrigation systems.
Farmers choose sprinklers with small trajectory angle when they
used treatment wastewater, or water is spraying below tree canopy.
while sprinklers with high trajectory angle used when spraying
above canopy.
Many NLG tasks such as summarization, dialogue response, or open domain question answering, focus primarily on a source text in order to generate a target response. This standard approach falls short, however, when a user's intent or context of work
is not easily recoverable based solely on that source text-- a scenario that we argue is more of the rule than the exception. In this work, we argue that NLG systems in general should place a much higher level of emphasis on making use of additional context, and suggest that relevance (as used in Information Retrieval) be thought of as a crucial tool for designing user-oriented text-generating tasks. We further discuss possible harms and hazards around such personalization, and argue that value-sensitive design represents a crucial path forward through these challenges.
The study was carried out in apple orchard and at the laboratories of Agricultural
Scientific Research Center, and Pome and Grapevine Division in Sweida (GCSAR),
Syria, during the growing seasons of 2015 and 2016 to study the effect of organic
res
idues, and boron and zinc addition on some soil characters, fruit set ratio and
some fruits qualitative traits in Starking delicious apple cultivar in Sweida.
