in order to study the correlation between morphophenological and quantitative traits with yield and to determine the most important traits for yield, 600 ecotypes of mung bean were evaluated in normal and limited irrigation conditions through augmented design. computation of correlation coefficients showed that in two conditions, number of pods per plant, harvest index and biological yield had ...
In order to study yield component and determinate the contribution of stem reserves to corn yield under effect of different densities and interference periods of sorghum, a factorial experiment based on randomized complete block design with three replications was conducted in 2002 on the Research Farm of the Faculty of Agriculture Tabriz University. Experimental factors were sorghum interferenc...
thirty-three M7 soybean mutant lines which originated by γ ray (co-60) from cultivar L17 irradiated with doses150, 200 and 250 Gray (absorbed dose), L17 cultivar and two commercial cultivars Clark (CL) and Williams (WI) were evaluated in view of some agronomical and morphological traits under completely randomized design with three replications. In M7 mutant lines all traits except number of s...
Defining interrelationship of growth analysis factors and yield of crop plants is important in the field crop production practices. This research was aimed at studying growth factors and grain yield of five maize hybrids, consisting of S.C.704, S.C.700, S.C.647, S.C.604, and S.C.301, using two 4-replicate RCBD experiments in Isfahan, in Summer 2004. While one experiment was irrigated normally, ...
Genetic variation of 300 genotypes of durum wheat comprising CIMMYT/ICARDA and Iranian germplasm was evaluated in 1999-2000 at Researh Farm of College of Agriculture, Isfahan University of Technology located at Lavark, NaJaf-Abad. Days to heading, days to maturity, plant height, spike length, grain weight per spike, number of grain per spike, number of spikes per m2, 1000-grain weight, test wei...
The study aimed to determine factors affecting the dry period length and effect of dry days on milk yield, milk composition and lactation length in the next lactation of dairy cows. Data used for analysis included 7264 lactation records collected from 2012 to 2016 on 4737 Holstein cows raised in 152 herds. The statistical model used to determine the factors influencing the dry period length sho...
