The accuracy prediction for the crop yield is conducive to food security in regions and/or nations. To some extent, model yields combining mechanism with statistical regression (SRM) can improve timeliness and robustness of final prediction. In this study, accumulated biomass (AB) simulated by Agricultural Production Systems sIMulator (APSIM) multiple climate indices (e.g., suitability extreme ...
Shoot extension of Rhododendron ‘Sir Robert Peel’ was reduced, but flowering was more precocious after treatment of plants with paclobutrazol. All of the drench rates tested (0.05 to 0.4 g a.i./pot) proved excessive and resulted in prolonged shoot growth reduction but greatly increased the number of flowers. However, flowers produced at the higher drench rates were grossly malformed and unaccep...
Introduction: Studies have indicated that metformine has different effects on learning and memory. In this study, both acute and chronic therapeutic effects of metformin on memory retrieval and some serum oxidative stress factors in Streptozotocin -induced Alzheimeric male rats were investigated. Methods: In this experimental study, 48 rats were divided into six groups (n=8) as follows: saline...
in order to study a the effect of different levels of ammonium sulfate on photosynthesis pigments, essential oil content and components in summer savory, an experiment was conducted based on randomized complete block design (rcbd) with five treatments and three replications on karaj climate conditions. the treatments included five levels of ammonium sulfate consist of: control (without fertiliz...
BACKGROUND Caudal anaesthesia is a common procedure for infants and children undergoing subumbilical surgery, mostly performed in conjunction with general anaesthesia. Even if complications are rare, the risk of postoperative apnoea is significant, especially in infants born preterm or operated upon before 46 weeks of post-conceptual age. Caudal block in sedated, spontaneously breathing patient...
To investigate the effect of different irrigation levels on yield and yield components of two cotton cultivar, a two-year experiment (2006-2007) was carried out at Agricultural Research Center of Kabotarabad, Isfahan, Iran. In this experiment, the strip split-plot design, as randomized complete blocks with four replications, was used. Main plots consisted of six levels of irrigation (T1 to T6, ...
this study was conducted to investigate the effect of aflatoxin b1 (afb1) on performance and egg quality in broiler breeders and the abatement of its deteriorative effect through its counteraction with herbal mycotoxin binder (hmb). thirty-six, 28-wk-old broiler breeder hens were allotted to one of the three treatments of: (1) basal diet (control),(2) control plus 500 μg kg-1 afb1 and (3) contr...
The USDA-ARS Sugarcane Variety Development Program in Houma, LA aims to maximize the number of panicles available for crossing through artificial manipulation of the environment. In a three-year study, the effect of growing media, fertilizer treatment, and their interaction on sugarcane flowering (% of panicles emerged), and number of days to flowering (DTF) under an artificial photoperiod trea...
This study was carried out to determine some yield characteristics of Hungarian vetch varieties and evaluate them as bee pastures based on bee-plant relationship. Eight were used in the study. In Bingöl province, where research out, flowering started April 18. Counts 23 ended May 11. remained blooming for about three weeks province. An average 14.9 bees per m2 visited flower an 9.0 seconds. It ...
