Evaluation of morphological characteristics in Venezuelan maize (Zea mays L.) genotypes under drought stress Scientia Agricola
Camacho,R.G.; Caraballo,D.F..
A greenhouse experiment was carried out to evaluate the responses among 10 maize (Zea mays L.) genotypes under drought stress. Seeds were planted in washed sand in plastic pots. The research was established in a completely random design with ten treatments and three replicate pots. The plants were harvested four weeks after sowning, and leaf area per plant (LA), root volume (RV), longest root length (LRL), plant height (PH), fresh (RFW) and dry weight (ROW) of roots, shoot dry weight (SOW), RDW/SDW ratio, and total dry matter production (TDM) were determined. Significant varietal differences for all characters were found, except for LRL. The data obtained allowed to identify Cargill-163 as a poor genotype at low water supply. Danac-3006, FM-6,...

ABSTRACT Foliar fertilization is an important agricultural technique that has stood out for its ease of use and can contribute to the production of high-quality and -vigor cashew seedlings. The objective of this study was to evaluate the effect of foliar fertilizer rates and time of application on ‘BRS 226’ dwarf cashew seedlings after grafting. The experiment was carried out in a completely randomized design, with five treatments and 24 replicates. Each experimental unit consisted of one plant. The commercial product (NPK 20-20-20) was used at the recommended rate for fruit crops in general, 2.5 g L-1. Foliar fertilizer applications at 45 and 60 days after grafting (DAG), with 50% of the recommended rate (1.25 g L-1), or at 80 DAG, with 100% of the...

การปรับค่าสัมประสิทธิ์เพื่อปรับปรุงความแม่นยำของแบบจำลอง CSM-CROPGRO-Peanut ในการเจริญเติบโตของรากถั่วลิสง Thai Agricultural

Important input factors that affect root growth under field conditions have not been included in CSM-CROPGRO-Peanut model, resulting in poor simulation of some rooting traits. Hence, the objective of this study was to optimize root growth factors for obtaining the suitable value with particular genotypes and environments. Two root growth factors including 1) fraction partitioning to leaf (YLEAF) and 2) root growth factor in soil layers were adjusted. Root mean square error (RMSE) and index of agreement (d) that were the statistical agreement between observed data and simulated data were used for considering the best fit values of root growth factor. The statistical agreement between observed and simulated data of root dry weight and root length density...
