within-field variation of wheat yield and spatial pattern of weed density and soil nitrogen were evaluated by geostatistical methods. samples were taken from a 90×120 m area located in a 3.8 ha wheat field. soil nitrogen content and weed density at tillering and wheat yield at maturity were measured in 1 m2 plots located at the center of 10×10 m grids. grain yield was varied between 1.5-4.9 t h...
A Split plot experiment based on randomized complete block design (RCBD) with three replications was conducted in 2012,Treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (Sardari, Rijav, Biseton and Rashid) as the second factor. Plant characteristics such as plant height, length o...
HE importance of day length as a determining factor in the time of T floral initiation in plants was first reported by GARNER and ALLARD (1920). Since then numerous investigations have been conducted on this phenomenon, and many plants have been classified into short-day, long-day and day-neutral types on the basis of their response to photoperiod. All known varieties of teosinte belong to the ...
Tiller number, an important growth parameter for rice cultivation, is still being assessed manually. This work investigated the influence of dataset composition on performance deep learning models tiller number estimation in rice. Four datasets were constructed early tillering, active and maximum tillering by applying concepts mixed varieties, class balance, data augmentation. YOLOv4 trained to...
proper application of n fertilizer and its optimization for increasing the economic yield of rice is definitely important. in order to determine the best n application method and amount according to growth stages of hybrid rice, an experiment was carried out at experimental farm of rrii in a factorial experiment based on a randomized complete block design with 3 replications. the treatments inc...
a split plot experiment based on randomized complete block design (rcbd) with three replications was conducted in 2012,treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (sardari, rijav, biseton and rashid) as the second factor. plant characteristics such as plant height, length o...
In order to investigate the effect of nitrogen fertilizer and plant density on the agronomic characteristics of rice cv. Tarom Hashemi, a field experiment was carried out as a randomized complete blocks design with three replications during 2018 and 2019 in a farm located in Sari, north of Iran. The present study consisted of 10 levels of plant density (hills m-2) and N fertilizer, named T1 (20...
Rice (Oryza sativa) is one of the most important crops in the world. Several rice insertional mutant libraries are publicly available for systematic analysis of gene functions. However, the tagging efficiency of these mutant resources-the relationship between genotype and phenotype-is very low. We used whole-genome sequencing to analyze a T-DNA-tagged transformant from the Taiwan Rice Insertion...
