to compare the quantity and quality of forge production in intercropping systems with maize, pinto bean and pumpkin, an experiment based on randomized complete block design with three replications was conducted at faculty of agricultural science, university of guilan, during 2012 growing season. the treatments consisted of maize, pinto bean and naked pumpkin sole cropping, maize – pinto bean an...

zafar as a new rapeseed cultivar is the cross which was made between 19h and sarigol line/cultivar in 2003. the pedigree selection was applied to mange the segregating generations. the results of evaluation made during 2008-09 and 2009-10 showed that zafar with an average seed yield of 3810 kg ha-1 was among superior genotypes identified. further evaluation on these genotypes as a mid-maturity/...

Except for the events RT73, MS8, RF3, and T45, event-specific detection methods for most commercialized genetically modified (GM) rapeseed varieties have not been established, and as a result, the enforcement of genetically modified organism labeling policies has been hindered. The genetically modified rapeseeds, MS1xRF1 and MS1xRF2, are 2 of 11 approved GM-rapeseed varieties for commercializat...

Currently, cold temperatures are one of the main factors threatening rapeseed production worldwide; thus, it is imperative to identify cold-resistant germplasm and to cultivate cold-resistant rapeseed varieties. In this study, the cold resistance of four Brassica rapa varieties was analyzed. The cold resistance of Longyou6 and Longyou7 was better than that of Tianyou2 and Tianyou4. Thus, an F2 ...

In order to investigate the changes in fatty acids composition of rapeseed lines under Chitosan application, a factorial split-plot experiment was conducted based on RCBD in 3 replications during 2 years (2014-2016) in Karaj, Iran. Irrigation and Chitosan as main plots and cultivar in sub-plots were considered. In this study, treatmen...

Rapeseed-mustard oil is an essential dietary component, in India. The modification of rapeseed- mustard for fatty acid composition of seed oil to develop new genotypes having alternative oil and meal characteristics has been an important objective in quality breeding. Moreover, Breeding efforts in India are in progress to develop double low varieties to meet the internationally acceptable stand...

The concept of critical nitrogen (Nc) concentration can be implemented to diagnose in-season plant nitrogen (N) status for optimizing N fertilizer management. The Nc dilution curves have been established for rice (Oryza sativa L.) grown in different climatic regions, yet no attempt has been made to develop the Nc dilution curve for double cropping rice regions. This study was undertaken to deve...

Estimating crop yield using remote sensing techniques has proven to be successful. However, sugarcane possesses unique characteristics; such as, a multi-year cropping cycle and plant height-limiting for midseason fertilizer application timing. Our study objective was to determine if sugarcane yield potential could be estimated using an in-season estimation of normalized difference vegetative in...

Depletion of non-renewable rock phosphate reserves and phosphorus (P) fertilizer price increases has renewed interest in breeding P-efficient varieties. Internal P utilization efficiency (PUE) is of prime interest because there has been no progress to date in breeding for high PUE. We characterized the genotypic variation for PUE present within the rice gene pool by using a hydroponic system th...

short growing season in cold regions is an important factor in not achieving a maximum root yield in sugar beet crop. in an investigation on possible ways to limit the effect of short season culture on the crop, six harvest dates and three sugar beet varieties were considered. the experiment was conducted as a factorial with randomized complete block design in three replications, from 1996-1998...
