To assess the effect of non chemical management of weed control on forage Sorghum (Sorghum bicolor) a field study was conducted in Varamin, Iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (W1= one time cultivation at 3-leaf stage using a duck foot cultivator, W2<...

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...

The paper presents the results of a triennial study sowing system influence on yied, grain weight per head, plant set ha and moisture medium-early sunflower hybrid . Standard was performed with PSK OLT machine at row spacing amounting to 70 cm, while twin MaterMacc Twin Row-2 22*48 cm. Both machines were adjusted according ISO standard 7256/1 7256/2, high QFI index (PSK OLT: 96.32 %; Row-2: 93....

in order to evaluate the effects of yield and yield components and weed diversity and density in row intercropping for wheat and canola, a field experiment was conducted based on a complete randomized block design with three replications at the agricultural research station of ferdowsi university of mashhad, iran during two growing seasons of 2008-2009 and 2009-2010. treatments included four pa...

High yielding superior groundnut cultivar development is the main objective of breeding programs. A four-year study was conducted in Eastern Mediterranean Agricultural Research Institute 2001, 2002, 2003 and 2004 growing seasons to evaluate for yield quality characteristics 80 varieties. The field experiments were laid out a 3 replicated randomized complete block design. In research, row spacin...

Row structure causes the anisotropy of microwave brightness temperature (TB) of soil surface, and it also can affect soil moisture retrieval accuracy when its influence is ignored in the inversion model. To study the effect of typical row structure on the retrieved soil moisture and evaluate if there is a need to introduce this effect into the inversion model, two ground-based experiments were ...

Distribution of Xiphinema americanum and four Meloidogyne spp, was studied in a vineyard over a 13-mo. period. The X. arnericanum population was concd in the upper 60-cm of undisturbed soil in the vine row, whereas the Meloidogyne species were distributed both in and between rows and to greater depths, similar to the distribution of the root system. Samples for assessment of X. americanum densi...
