in in order to investigating changes range of oil yield and percentage attention to plant density on three varieties of black seed, an experiment was conducted in the form of factorial based on completely randomized block designs (rcbd) with 4 replications in saat-loui agricultural station of west azerbaijan province. in this research, the first factor (a) contained two levels 20 and 40 cm inte...

ABSTRACT- In order to study the effects of different irrigation regimes and plant density on yield and yield components of bean, a split plot arrangement was conducted in complete randomized block design during two years. The foremost variable was four levels of irrigation: 60, 80, 100, and 120% of the potential evapotranspiration. The second variable was within the row spacing of 5 cm (D1), 10...

Increasing level of carbon dioxide CO2 due to industrial activity is primarily cause of global warming. Planting Artoplex lentiformis can help to reduce atmospheric CO2 buildup partly replacing use of fuels and by carbon storage. The objective of this study was to determine the effects of row spacing on carbon storage. A split- plot design with three replications included three row spacing (2×2...

in order to evaluation of plant densities and row spacing effects on growth and yield of wheat, an experiment was conducted by using four plant densities (125, 250, 375 and 500 plants per m2),two row spacing (12.5 and 25 cm), in a randomized complete block design with three replicates in anbare-ololum reign in rainfed and saline conditions during 2008-2009. results showed that leaf area index (...

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...

The objective of the study was to evaluate performance a vacuum single-seed planter in field conditions optimize some operating parameters maize production. Three forward speed tractor (4.0, 5.4 and 7.9 km h-1) five target seed spacing (102, 147, 195, 247 309 mm) were evaluated by examining mean spacing, coefficient precision miss index, multiple quality feed sowing depth, deviation from row (i...
