The newly-found petroglyphs of Ariyeh in Khorasan Razavi province, North-Eastern Iran

Despite the distribution of known rock art in Iran showing a main concentration in central and western Iran, research activities undertaken in the very last decades led to the identification of sites in eastern Iran as well. In 2018 a new rock art site was discovered close to Ariyeh, Khorasan Razavi province, NE Iran. Here we present a case report on these newly found petroglyphs that are now in imminent danger due to recent vandalism. According to the represented iconography, its features, style, and patina, it seems that the Ariyeh rock art was produced over a long chronology, from the late Prehistory to the Islamic period. The discovery of the petroglyphs of Ariyeh has strong implications towards the understanding of the relationships among the different sites and their use, function, and meaning, in order to understand cultural connections occurred between the Iranian plateau and the surrounding areas over the millennia

Newly discovered rock art sites in Balandar, Mashhad province, north-eastern Iran

The site of Pire Mazar Balandar (or PMB001) is located near the village of Balandar in the Khorasan region of north-eastern Iran (33 degrees 0937.64N, 59 degrees 2952E; Figure 1). It consists of an outcrop of volcanic rock on a mountain peak (1532m asl) on the north-eastern side of the Binaloud range, above the city of Mashhad (Figure 2)

The Amount and Timing of Foliar Urea Application Effect on Maize and Forage Sorghum Proteins

This study was carried out for investigating the effect of amount and timing of foliar urea in increasing silage yield and protein content of fodder, in a maize field in Neyshabour, Khorasan Razavi Province during 2011 summer crop season. A split plot design with factorial arrangement and three replications were used. Treatments were timing of foliar urea application (a week before tasselling, mid anthesis and early milk stage), urea levels (zero (check), five and 7.5 g.lit-1) and two hybrids of corn (Sc 704) and forage sorghum (speed feed). The results indicated that the concentration of nitrogen had significant effect to increase forage protein and silage yield (correcting by 280 g.kg-1 of dry matter). The highest forage protein concentrations for both crops and silage yield were achieved with 7.5 g.lit-1 of urea application, but the silage yield of sorghum was more than that of corn. The results showed that urea spraying can effectively increase the fodder nitrogen and silage protein, respectively, with the least possible cost, and in this respect it has an important role in providing quality and environmental safe forage for producer and consumer, meanwhile the adverse effects of excessive use of nitrogen fertilizer are reduced.   </div
