the water deficit is the most important limiting non-biological factor to achieve the potential yield of crops. to evaluate the effect of silicon application on yield of millet under drought stress in field an experimental was carried out. treatments were included three irrigation regimes after 60 (non-stress), 90 (moderate stress) and 120 (severe stress) mm evaporation from evaporation pan, cl...

In order to explore the optimal cultivar × sowing date plant density for summer maize (Zea mays L.) in Northern Huang–Huai–Hai (HHH) Plain of China, field experiments were conducted over two consecutive years (2018–2019) on a loam soil HHH Plain. A split–split plot design was employed this study, and main plots included three cultivars (HM1: early-maturing cultivar; ZD958: medium-maturing DH605...

water deficiency is one of the most important factors for limiting crop yield in arid and semiarid regions. symbiosis with a variety of microorganisms in these regions is one of the modern ecological approaches for sustainable agriculture to reduce damages caused by environmental stresses. symbiotic of arbuscular mycorrhizal fungi (am) with the roots of crops has shown positive effects on agric...

Progress in improving crop growth is an absolute goal despite the influence multifactorial components have on crop yield and quality. An Avalon × Cadenza doubled-haploid wheat mapping population was used to study the leaf metabolome of field grown wheat at weekly intervals during the time in which the canopy contributes to grain filling, i.e., from anthesis to 5 weeks post-anthesis. Wheat was g...

Flowering depends upon long-distance transport to supply water for reproductive mechanisms to function. Previous physiological studies suggested that flowers operated uncoupled from stem xylem transport and received water primarily from the phloem. We demonstrate that the water balance of Southern magnolia (Magnolia grandiflora) flowers is regulated in a manner opposite from that of previously ...

abstract:background and objectives:in arid and semi-arid regions, salinity is a serious and chronic problem for agriculture. due to the improved methods of irrigation and mechanization this methods to increase water use efficiency and enhance the uniformity of water distribution in the field, is very important. main area of farming cotton in iran is about 150000 ha, which in kerman province mos...

given the scarcity of water resources using modern methods of irrigation in agriculture will be inevitable. today, process improvement, development and use of drip irrigation practices as one of the most advanced methods of irrigation in agriculture is increasing. so this study was conducted to determine the impacts of irrigation interval and drip irrigation method and their interactions on yie...
