In the southeastern U.S. Coastal Plains, supplemental irrigation is required to reduce the impact of short‐term droughts and yield‐reducing plant water stress that can occur at least biennially. Sprinkler irrigation is commonly used to water agronomic crops in the region. Microirrigation is typically used for high value fruit and vegetable crops. In recent years and at some locations, microirri...

A field experiment was conducted during Kharif 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). To study treatments consisting three levels Nitrogen such as, 80, 100 and 120 kg/ha with spacing as 75 x 10 cm2, 60 20 cm2 45 30 cm2. The soil experimental plot sandy loam in texture, nearly neutral reaction (pH 7.1), low organic carbon (0.28%), available N (225 kg/ha), P ...

Abstract Glyphosate-resistant (GR) Palmer amaranth is one of the most difficult to control weeds in soybean production fields Nebraska and United States. An integrated approach required for effective management GR amaranth. Cultural practices such as narrow row spacing might augment herbicide efficacy The objectives this study were evaluate effect programs dicamba/glyphosate-resistant (DGR) soy...

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...

This paper presents a mapping method for wide row crop fields. The resulting map shows the crop rows and weeds present in the inter-row spacing. Because field videos are acquired with a camera mounted on top of an agricultural vehicle, a method for image sequence stabilization was needed and consequently designed and developed. The proposed stabilization method uses the centers of some crop row...

Buckwheat is an economically important gluten free cereal, and it a good source of protein, fiber, energy. The field experiments with buckwheat variety “Novosadska” were set in two experimental years Pancevo, Serbia. aim this study was to determine the most optimal technology for production. aims investigate effects (1) row spacing: RS1-25 cm RS2-50 cm; (2) nutrition variants: (N1) 0 kg ha?1 NP...

Photovoltaic and solar thermal projects require accurate irradiance data models for the design, assessment, forecasting of power output. For panels collectors installed in arrays, view toward sky ground is restricted by surrounding rows. This paper analyzes impact obstructions on diffuse distribution fixed-tilt addressing insufficient research coverage to date. Irradiance was measured using hig...

drip irrigation is the most efficient technique known for improving irrigation water management. a two-year study was conducted to determine the effects of drip and furrow irrigation methods on yield and quality of sugar beet in north of khuzestan. in the first year, the experimental design was a completely randomized block design with three replications. treatments were, three drip irrigation ...

Globally, one of the most devastating diseases sorghum is anthracnose incited by Colletotrichum sublineola. During 2019 and 2020 growing seasons, 94 64 accessions from Ethiopian germplasm collection maintained National Genetic Resources Program United States Department Agriculture were evaluated for resistance. Seeds planted in 1.8 m rows with 0.9 row spacing a randomized complete block design....

Algorithms were developed to process video of maize rows and extract plant features to estimate density and spacing of early growth stage maize plants. The Otsu method was modified to compensate for varied amount of plant segmentation noise presented in different operating conditions. Three features were extracted and used to differentiate between weeds and maize plants: projected plant canopy ...
