Prediction of barley yield is an attempt to accurately forecast the outcome of a specific situation, using as input information extracted from a set of data features that potentially describe the situation. In this study, an attempt has been made to analyze and compare multiple linear regression (MLR), and artificial neural network (ANN) including multi-layer p erceptron (MLP) and r adial basis...
to evaluate the effect of zn sulfate foliar application on morphologic and quantitative characteristics of safflower (carthamus tinctorius l.) cultivars, a field experiment carried out in ramin agriculture and natural resources university of khouzestan, iran, in a factorial arrangement in a randomized complete block design with four replications, during 2012-2013. treatments consisted of two sp...
in order to evaluate arbuscular mycorrhiza (glomuss mossea) and mycorrhiza-like (piriformospora indica) effects on yield, yield components and some morphological (cv. azar 2) traits of wheat (triticum aestivum l.) under water deficit stress, a pot experiment was conducted as factorial experiment based on completely randomized design with four replications. treatments were drought stress at thre...
Effect of nitrogen (N) fertilizer levels and its split applications on yield and yield components of rice (Oryza sativa L.) Cv. Khazar was investigated in a completely randomized block design with 3 replications in a paddy light soil at Guilan province, Iran, 2003. In this experiment, six treatments including: T1-control (no N fertilizer) T2- 40 kg/ha N (at transplanting time) T3- 80 kg/ha N (a...
Identification and introduce of high potential and water deficit stress tolerant is one of effective methods that caused to economic production beside other methods of water deficit management. In order to identification of barley lines, 9 barley elite lines and Bahman variety (check) studied under full irrigation and water deficit stress conditions in season cropping years 2013-2015. The resul...

This study aimed to investigate the relationship between morphophysiological and phenology traits with grain yield to determine the best indices of direct and indirect selection in the field of genetic improvement of aerobic rice grain yield in Khuzestan province with 12 aerobic rice genotypes. The traits such as include the grain yield as the dependent variable and total dry matter, panicle we...
the present study aimed at investigating the effect of different levels of nitrogen on yield and yield components of bread and durum wheat. to this end the experiment was conducted in 2010-2011 in south west of iran as split plots based on randomized complete block design with three replications. main plot included four levels of nitrogen 60, 120, 180, 240 kg.ha-1 and the sub plot included four...

Extended Abstract Introduction and Objective: Selection of desirable hybrids compared to other maize hybrids (Zea mays L.) is one of the methods used to achieve high grain yield in maize. Also, the most important morphological features affecting grain yield can be used in the selection and introduction of genotypes. Material and Methods: This study was conducted to investigate the relationshi...
This study was conducted to evaluate the quantitative and qualitative characteristics and grain yield stability of 10 promising lines of rice, compared to cultivar Khazar as the checking variety, in Rasht, Roudsar and Talesh cities of Guilan province, Iran, in three years. The experiment was conducted using a randomized complete block design with three replications. Characteristics such as grai...
