The effect of crop sequence on parasitism of second-stage juveniles (J2) of Heterodera glycines by Hirsutella rhossiliensis was investigated. Data were collected from plots of a long-term crop rotation experiment established in 1982. Crop sequences included (i) continuous monoculture of corn and soybean; (ii) annual rotation of the two crops; and (iii) 1, 2, 3, 4, or 5 years of each crop follow...
in order to evaluate the effect of different levels of sowing dates and plant density on grain yield and its components in chickpea var. arman, a field study was conducted at ekbatan research field station of agricultural and natural resources research center of hamedan province under rainfed condition during 2009-2010 cropping season. treatments were arranged as split plot on the basis of rand...
In this study, the an AMMI analysis (additive the main effects and the multiplicative interaction effects) was used to evaluate the yield stability of nine oats genotypes (4 Canadian cultivars and 5 Turkish breeding lines) and Makoi barley (as ckeck) in the 6 environments (3 dates of planting of Oct.12, Oct.31 and Nov.21 and 3 sowing densities of 300, 375 and 450 seeds/m2). The experiment was c...
In order to investigate the effects of plant density, time and number of weed control on yield and yield components on corn hybrids, a factorial experiment in completely randomized blocks design with 3 replications was conducted in 2011 growth season at Research farm of College of Agriculture, University of Shahid Bahonar, Kerman. Weed control treatments were including: weed control during corn...
