to study the effects of different n fertilizer on berseem clover forage quality in an intercropping with basil, this experiment was conducted in research farm of college of agriculture, university of tehran in 2011. experimental treatments were arranged as split plots based on a randomized complete block design with three replications. different n fertilizers consisted of control (no n fertiliz...

Abstract The research stages consist of identification on potential application agricultural technology and study cropping patterns, namely pattern shallot-shallot-shallot shallot-peanut- shallot. was carried out from November to October 2017 in mountainous area that many farmers were engaged nomadic farming. aims identify problems land use for the appropriate patterns increase income shifting ...

The paradigm of integrated water resources management requires coupled analysis of hydrology and water resources in a river basin. Population growth and uncertainties due to climate change make historic data not a reliable source of information for future planning of water resources, hence necessitating climate and landuse change impact studies. This work presents an integrated modeling approac...

Alley cropping may promote greater sequestration of soil organic carbon. The objective of this study was to examine spatial variability of soil organic carbon (C) and nitrogen (N) fractions relative to tree rows in established alley cropping systems in north central Missouri. Soils were collected to a depth of 30 cm from two alley cropped sites, a 19-yr-old pecan (Carya illinoinensis)/bluegrass...

Both large and small scale migrations of Helicoverpa armigera Hübner in Australia were investigated using AMOVA analysis and genetic assignment tests. Five microsatellite loci were screened across 3142 individuals from 16 localities in eight major cotton and grain growing regions within Australia, over a 38-month period (November 1999 to January 2003). From November 1999 to March 2001 relativel...

[1] Validations of the DeNitrification-DeComposition (DNDC) model against field data sets of trace gases (CH4, N2O, and NO) emitted from cropping systems in Japan, China, and Thailand were conducted. The model-simulated results were in agreement with seasonal N2O emissions from a lowland soil in Japan from 1995 to 2000 and seasonal CH4 emissions from rice fields in China, but failed to simulate...

in order to study the yield and forage quality of intercropping barley (hordeum vulgare) and mustard (sinapis alba) in different planting dates, a factorial experiment based on randomized completely block design with three replications was carried out at farm research station, gonbad -e- qabus university. factors were included as three planting dates (15 november, 6 and 20 december 2006) and fo...

intercropping is considered for increasing and stability of yield per unit. in order to study the effects of different intercropping arrangements on sorghum and mungbean yield and to find the land use advantage in the intercropping system, an experiment was carried out based on a randomized complete block design with seven treatments and three replications at the research farm, faculty of agric...
