Abstract The aim of the research is to study effect stages spraying nano-microelements on some yield characteristics and economic feasibility wheat varieties. Soil with a mixture clay texture using split plank design random complete sectors (R.C.B.D) cultivars coded (Abu Ragheef V1, Baghdad V2, Babil V3, Aba 99 V4) occupied main panels, while (tillering stage S1, booting S2, flowering S3) secon...

Since the work of André Martinet back in the 60’s [7], the notion of ‘economy’ has been accepted as one of the main principles underlying the organization of phonological inventories (hereafter PI). This principle, also named MUAF (‘Maximal Use of Available Features’) by John Ohala [8], states that PI are organized along a few phonetic dimensions that they tend to maximize in terms of number of...

The existence of diverse communities of plant species, including crops is crucial for maintaining the ecological balance between human kind and environment. Their existence also ensures the continuous food supply to human and animals. Therefore, it is critical to use modern biotechnological techniques in breeding scheme to increase the productivity of the economical crops and plants so we can a...

Yield and quality are central to sustainable crop production. Due to biotic stress, yield loss upto 52 per cent. Chemical control of insect and disease is not feasible for environments and economical not viable. Host plant resistance is the only safe, economical, and environment friendly way for the absolute control of this devastating pest and disease. Historically, long-term cultivation of va...

One of the fundamental social and economic characteristics of the southern countries is the lack of development of spatial planning system whose symptom is the irregular expansion of urban settlements. Due to the ecological traits and national policy-making manner, this expansion has caused the centralization of regional metropolises in these countries. In the geographical spaces of Iran, speci...

A 2×2×2 factorial design experiment was carried out with two levels of protein (20 and 22%), two levels of lysine (1.05 and 1.15%) and two levels of total sulfur amino acids (TSAA) (0.8 and 0.9%) to investigate their effect on growth performance and carcass characteristics of growing Japanese quail. A total number of 408 unsexed one week old Japanese quail chicks were randomly distributed into ...
