In the tropics, cowpea is often intercropped with maize. Little is known about the effect of the intercropped maize on N2-fixation by cowpea or how intercropping affects nitrogen fertilizer use efficiency or soil N-uptake of both crops. Cowpea and maize were grown as a monocrop at row spacings of 40, 50, 60, 80, and 120 cm and intercropped at row spacing of 40, 50, and 60 cm. Plots were fertili...

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...

Kenaf (Hibiscus cannabinus L. ), a warm-season annual plant, has shown potential as an alternate source of fiber in the United States. Although preliminary research has indicated feasibility ofkenaf production in Virginia, production details are lacking. Field experiments were conducted during 1995 and 1996 to determine optimal row spacing and fertilizer needs, and to compare available kenaf cu...

The experiment was conducted to determine optimum plant spacing and suitable variety as well identify the interaction effect of varieties Intra-row on yield sorghum. having a factorial arrangement three (Geremew, Lalo farmer’s local variety) intra-row levels (10 cm, 15 cm 20 cm) laid out in randomized complete block design (RCBD) with replications. According current results, were significantly ...

Image processing algorithms for individual corn plant and plant stem center identification were developed. These algorithms were applied to mosaicked crop row image for automatically measuring corn plant spacing at early growth stages. These algorithms utilized multiple sources of information for corn plant detection and plant center location estimation including plant color, plant morphologica...

The objective was to evaluate the epicotyl length of seedlings soybean cultivars in field, submitted plant densification by reducing inter-row spacing. Two field experiments were conducted Rio Paranaíba state Minas Gerais and effect reduced spacing (20 cm, 30 40 cm 50 between rows) evaluated. assessment done using a millimeter ruler when plants reached V2 development stage. randomized block des...

Optimum seeding rate and row spacing are important for uniform crop establishment harvest of quality seed. Field experiment was conducted at three locations in 2014 2015 to study the influence seed on multiplication factor yield durum wheat. Triplicate split plot design used. The highest found a 125 kg ha−1 with 10 cm but not significant rates 100 spacing, 75 20 2014, 150 Debre Zeit. At Chefe D...
