Partial stage and complete life-cycle growth curves of Brahman cattle were obtained for small, medium, and large frame sizes for a herd under grazing conditions in a subtropical environment. Data were grouped into three stages: birth to weaning (stage 1), weaning to 20 mo (males) or 32 mo (females) of age (stage 2), and 32 mo of age to maturity (females only; stage 3). Within each stage, multip...

Conducting research on monitoring contaminated fields by heavy metals is necessary in order to achieve sustainable agriculture, increase product quality and keep public health. This study was carried out using split plot experiment based on randomized complete blocks design with three replications during 2014-2015 in Shavor Agricultural Research Center in order to evaluate the effect of croppin...

Soybean (Glycine max [L.] Merr. cv Braxton) plants were grown in sandy soil with only natural rainfall (N) or with supplemental irrigation (I). Water-stressed plants grew more extensive root systems, whereas irrigated plants developed larger shoots and smaller root systems. Maximum stomatal apertures were observed at the beginning of each photoperiod. Partial stomatal closure occurred each afte...

To determine salt sensitivity for wheat at various growth stages, a factorial experiment arranged as randomized complete block design was conducted in the ambient environment at the National Salinity Research Center, Yazd, Iran. Treatment were two cultivars of wheat (Kavir & Roshan) and salinity imposed at emergence, tillering, stem elongation, spike emergence and one week after anthesis. A con...

This study attempts to validate the stages of growth hypothesis by analyzing data concerning the benchmarks that were prescribed by Nolan [ 15]. Although the hypothesis was not validated using the entire set of benchmarks for each stage, individual benchmarks were related to various DP management issues. The joint relationship of user awareness and technology to various management issues was al...
