abstract in order to study the effect of planting season (autumn and spring) and plant density on growth traits and flower yield (dry weight of flower) of matricaria (matricaria chamomilla), an experiment was carried out at the research field of agricultural faculty of shirvan, affiliated to ferdowsi university of mashhad. a split plot design with two factors, including planting time and plant ...

in order to investigate the effect of crop row spacing and cocklebur (xanthium strumarium) densities on height, leaf area index and total dry matter of two sesame cultivars, a field experiment was conducted in 2009-2010 growing season at research farm of university of agricultural sciences and natural resources of gorgan, iran. the experiment was established as factorial arrangement using a ran...

Accumulation of dry matter in siliqua, number of siliqua per plant, length of siliqua and seeds per siliqua of rapeseed (Brassica campestris L.) plants were studied under three irrigation levels (no irrigation, one irrigation at 30 DAS and two irrigations at 30 and 60 DAS) and three row spacing (20 cm, 30 cm and 40 cm). Th e experiment was carried out at Sher-e-Bangla Agricultural University (S...

biological fertilizers can be suitable alternative to chemical fertilizers to increase soil fertility and crop production in sustainable agriculture. in order to evaluation of integrated application of bio-fertilizers and chemical fertilizers on on quantitative and qualitative yield of ajowan in strip intercropping, a field experiment was conducted in a factorial design based on randomized comp...

Long-term research aimed to determine whether narrow row spacing and harvest weed seed destruction, in combination with herbicide use, would be sufficient to drive a Lolium rigidum population to extinction. A trial was run from 1987 to 2013, with treatments including crop row spacings of 9, 18, 27 or 36 cm and crop residue burning or retention. Herbicides were applied to reflect regional practi...

In the context of precision viticulture, remote sensing in the optical domain offers a potential way to map crop structure characteristics, such as vegetation cover fraction, row orientation or leaf area index, that are later used in decision support tools. A method based on the RGB color model imagery acquired with an unmanned aerial vehicle (UAV) is proposed to describe the vineyard 3D macro-...
