Understanding how blockage influences large wind farms is essential as the first row produces most energy and often used a reference for subsequent rows. We use large-eddy simulations to investigate farm by comparing stand-alone turbine, an infinite of turbines, with eight find that effect dense turbine arrays highly dependent on non-dimensional spacing. Spanwise neighboring turbines appear ben...

The seed potato cost is very important component in total production and account for 30 to 70% which varies depending on the country or region. Tuber size an factor decide requirement per unit area. Seed affects yield, graded marketable tuber yields. Standard of 25–125 g weight (30–55 mm) known as tubers India. Obtaining achieving higher potential cultivars. profile can be reduced expanded by a...

in order to study the effects of intra and inter-row spaces and planting pattern on the yield components, seed and oil yield of pumpkin (cucurbita pepo l.), a field experiment was conducted as split-split plot based on randomized block design with three replications during 2009-2010 at the agricultural research station of ferdowsi university of mashhad, iran. two levels of inter-row space (1 an...

The purpose of this paper is to introduce a new technique for row spacing measurement in a wire array using giant magnetoresistive (GMR) sensor. The self-rectifying property of the GMR-based probes leads to accurately detection of the magnetic field fluctuations caused by surface-breaking cracks in conductive materials, shape-induced magnetic anisotropy, etc. The ability to manufacture probes h...

A field trial was conducted at the research farm of RRL, Jorhat during 1995 and 1996 to study the performance of Mentha Piperita under varying dates of planting and row spacings, maximum herbage and oil yield were obtained from January plants crops. Yield deceased when planting was delayed planting at a closer row spacing of 45 cm recorded the maximum herbage yield of 61'92 q/a while the yield ...

The study was conducted during 2013/14 main cropping season in Ebinat district with the aim of studying effects seeding rates and row sowing methods on growth, yield components tef. Planting material improved tef variety ‘Quencho’ (DZ-01-387) used as a test crop for experiments. Two factors 3 (5, 7.5 & 10 kg/ha) inter-row spacing (15cm, 20cm 25cm) were combined to form 9 treatment. treatments l...

Tef is a small-seeded staple crop endemic to Ethiopia. However, its yield low, constrained partly due improper agronomic practices and lodging. Thus, during the 2019–2020 cropping season, field experiment was carried out at Reef Tokko Taanne Hamilee in Hababo Guduru district, Western Ethiopia examine effects of seed rate inter-row spacing on growth, phenology, yield, lodging severity tef crop. ...

Rooftop buildings, mountain terrains, rivers, and lake beds may be oriented at different azimuths other than due south (in the northern hemisphere), on which photovoltaic (PV) systems installed. The present study presents a comprehensive point of view relation between inter-row spacing shading in multiple-row collectors PV fields; it analytically formulates associated losses for deployed any az...
