current study was initiated to generate the information on the effect of row-to-row distance of brassica crop, brassica napus l., on aphids population. three line spacing (20, 30 and 40 cm) with a constant nine cm plant to plant distance were evaluated on aphids infestation and its impact on seed yield. the collected and edited data on fixed parameters indicated that an inverse relation was fou...

The spatiotemporal distribution characteristics of water and nitrogen in the soil profile are essential influencing factors that determine development crop root systems. purpose this study was to clarify inter-row inter-tree variability moisture apple zone, effective diameter ranges trees influence absorption. method used a 2-year border irrigation experiment carried out traditional orchard Zun...

ABSTRACT- A real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. The image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. The image frames were processed by LabView® and MatLab®. The developed algorithm, based on weed coverage ratio and seg...

the objective of this study was to obtain relationships between plant leaf area (cm2plant-1) with leaf dry weight (g plant-1), vegetative dry weight (g plant-1) and plant height (cm) in faba bean (vicia faba l.). the experiment was conducted at the research farm of gorgan university of agricultural sciences in 2011-2012 growing season. the experimental design was a randomized complete block des...

Typically, low-pressure sprayers are used to uniformly apply pre- and post-emergent herbicides to control weeds in crop rows. An innovative machine for weed control in inter-row and intra-row areas, with a unique combination of inter-row cultivation tooling and intra-row band spraying for six rows and an electro-hydraulic side-shift frame controlled by a GPS system, was developed and evaluated....

This work addresses the problem of recovering multi-echo T1 or T2 weighted images from their partial K-space scans. Recent studies have shown that the best results are obtained when all the multi-echo images are reconstructed by simultaneously exploiting their intra-image spatial redundancy and inter-echo correlation. The aforesaid studies either stack the vectorised images (formed by row or co...

A field experiment was carried out for two successive cropping seasons in 2017 and 2018 at Shama Bulket, Semen Ari Woreda, South Omo Zone, Southern Ethiopia, to determine optimum seed rate inter-row spacing food barley production. The involved a factorial combination of three rates (80, 100 120 kg ha-1) (20, 30 40 cm). conducted using randomized complete block design with replications. results ...
