to evaluate the effects of presence of insect pollinators on quantity and quality of seeds of two common cultivars of onion (allium cepa l.), namely red azar shahr and yellow sweet spanish, an experiment in a factorial randomized complete block design was carried out at two sites. bulbs of equal size were planted with plant to plant 35 cm and row to row 50 cm spacing. at each site, experimental...

in order to evaluate the comparison of different intercropping patterns of cumin (cuminum cyminum l. ) with lentil (lens culinaris l.) in double crop, a field experiment was conducted based on a randomized complete block design with three replications and eight treatment at the farm located in west azerbaijan province - city nagadeh, iran during growing reason of 2011-2012. treatments included ...

An experiment to study the effect of inter and intra row spacing on the yielding performance of periwinkle species was conducted at Nagarjun Medicinal and Aromatic Plants Research Scheme, P. K. V., Akola (M. S.) during 1980 - 81 to 82 - 83. Three species viz., Catharanthus roseus, Catharanthus alba and Catharanthus oscillatus did not differ significantly in respect of dried foliage and root yie...

Maize is the most represented grain crop on world’s arable land. It mostly grown using standard sowing at an inter-row distance of 70 cm. However, growing in two rows (double-row sowing) increasingly common today. The aim this research was to determine influence different spatial distributions same population maize plants yield grains a larger range FAO hybrid maturing group. experiment lasted ...

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....

Limited water resources restrict winter wheat grain yield and quality in the Huang-Huai-Hai Plain of North China, and establishing optimal planting patterns according to crop water requirements is the key factor for achieving rational water use. In this paper, 4 planting patterns were applied, namely, uniform row (30 cm; traditional pattern), wide (40 cm)-narrow (20 cm) row, furrow (double line...

abstract a field experiment was conducted at iranian plant protection research farm in karaj during 2009 to evaluate the effects of diffrent planting patterns, times of mechanical control and herbicides application on weeds density and biomass in sugar beet farms. the experimental design was split–split plot based on randomized complete block design (rcbd) with four replications. planting patte...
