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...

this study was conducted to examine effects photothermal quotient on grain number of four wheat cultivars under four planting dates and four replications. the experiment conducted at the sabzevar agricultural sciences research during 2007-2008 and 2008-2009. various responses functions were evaluated to quantify the response of grain number to influencing parameters (environmental and non- envi...

This paper aims to evaluate and classify some upland rice varieties based on their morphological characteristics. The data used in the study was obtained from National Cereal Research Institute (NCRI), Badeggi -Nigeria. The study consists of 25 upland rice cultivars, which were extracted from 100 rice varieties ergo-listed in the institute. The experiment was conducted at Edozhigi in northcentr...

mapping the QTLs of agronomic and physiological traits, 149 double haploid (DH) lines from a cross between an Australian cultivar, Clipper (salt susceptible), and an Algerian landrace, Sahara3771 (salt tolerant), were evaluated under natural saline (Yazd Station, ECsoil=10-12.8 ds/m and ECwater= 9-10 ds/m) and normal (Karaj Station, ECsoil and ECwater ~2-2.5 ds/m) environments. There were remar...

let $r$ be a commutative ring and $m$ be an $r$-module with $t(m)$ as subset,   the set of torsion elements. the total graph of the module denoted   by $t(gamma(m))$, is the (undirected) graph with all elements of   $m$ as vertices, and for distinct elements  $n,m in m$, the   vertices $n$ and $m$ are adjacent if and only if $n+m in t(m)$. in this paper we   study the domination number of $t(ga...

An experiment was conducted at Institute of Agriculture and Animal Science (IAAS), Rampur, Nepal during July 2011 to September 2011 with an objectine to determine phenotypic variability of Nepalese finger millet landraces using descriptive statistics, cluster analysis and principal component analysis. FValue of REML procedure of mixed model analysis revealed that highly significant variation wa...
