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...

In Iran, more than 90% of raw materials including oils and oil seeds are provided through import. Camelina sativa L. as an oilseed crop, belongs to Brassicaceae family, has been shown in several experiments that need very little water and resistant to chilling injury than other plant oils, especially canola. This Experiment was conducted at research station of Campus of Agriculture and Natural ...

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 conventional cultivation of sugar beet the weeding and crust breaking are mostly performed manually. the objectives of this research were to design, fabricate and evaluate a soil crust breaker and weeding implement equipped with a detecting sensor. each unit consisted of a distance detecting sensor and a hydro-motor for driving the blades and pneumatic valves for moving the blades. the hydro...

in order to evaluate the effects of intercropping of maize- peanut, weeding and their planting design on weed population dynamics, an experiment was conducted as a factorial experiment in the form of rcbd with three replications at the research farm of agriculture center of zabol university (iran) in 2012. the treatments including sowing system in four levels as first factor  (sole maize, sole ...

manipulating of planting pattern is a method to increase the crop yield per unit of area which should be considered in different regions. in order to evaluate the effects of between and within row distances on growth indices of gahar mung bean, an experiment was conducted at the agricultural research center of ilam in 2004. the experiment was a split-plot arranged in an rcb design.three between...

A field trial was conducted during the Kharif season of 2020 to assess effect spatial and temporal crop geometry on phenology, yield agro meteorological indices hybrid maize at Agronomy Research Farm, FoA Wadura, Sopore, SKUAST-Kashmir. The experiment carried out in split- split plot design with dates sowing (17th SMW; D1), 19th D2 21st D3) as main treatments; varied row spacing (50 cm × 20 cm;...

Background: Pearlmillet is conventionally cultivated by farmers either broadcasting or uniform row spacing of 45 cm where it difficult to accommodate an intercrop. Modified planting pattern provides additional space for intercrop component as well harvest better solar energy in the system. Methods: The field experiment was conducted Department Agronomy, Tamil Nadu Agricultural University, Coimb...

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...
