: In order to study the effect of different nitrogen levels on yield components and seed yield of three barley cultivars, an experiment was conducted in 2011-2012 in a research farm of farming building of Islamic Azad University Khorasgan (Isfahan) Branch located in Khatunabad village (latitude 32o /40' N and Longitude 51o /48' E). A split plot layout within randomized com...

A crystalline Raman laser is pumped at 90° to the Raman laser axis by a single pass from a line-focused 532 nm pump laser of pulse duration 10 ns. The Raman laser threshold was 6.1 mJ, and at 12 mJ pump energy, a maximum output energy of 2.7 mJ was obtained with a slope efficiency of 46%. The threshold pump intensity is within a factor of 2 of the same device when end-pumped. The results highli...

We used outputs from a model of canopy carbon uptake [Dungan et al. (2004) Functional Ecology 18: 34–42] and measurements of irradiance (PAR, 400–700 nm) intercepted by the canopy to investigate the effect of daily changes in environmental conditions on daily light use efficiency, ε, for a canopy comprising two broadleaved New Zealand tree species with contrasting leaf habit. Irradiance absorbe...

The effect of organic manure and chemical fertilizers on vegetable crops and soil properties in the radish-stem amaranth-Indian spinach cropping pattern was studied in a homestead area of Gazipur district in Bangladesh. There were eight treatments poultry manure (PM) 5 t ha (T1), cowdung (CD) 10 t ha -1 (T2), household waste (HW) 10 t ha -1 (T3), PM 2.5 t ha -1 + reduced RDF (recommended dose o...

in the present study, the energetic and economic modeling of lentil and chickpea production in esfahan province of iran was conducted using adaptive neuro-fuzzy inference system (anfis) and linear regression. data were taken by interviewing and visiting of 140 lentil farms and 110 chickpea farms during 2014-2015 production period. the results showed that the yield and total energy consumption w...

X(n) = X1(n1) + · · ·+XN (nN ), n ∈ N0 . Here, nj denotes the jth coordinate of n ∈ N0 . We are following the standard convention of starting (ordinary) random walks at the origin. That is, Xj(0) = 0 for all j = 1, . . . , N . From now on, N will always denote the temporal dimension and d the spatial one, to use the standard language of stochastic processes. In order to describe a natural parti...

recently, increase in crop production depends on better seedling establishment, emergence rate and uniformity. thus, an experiment was carried out in a randomized complete block design with 8 fertilizer treatments and 4 replications in 2008 at sari agricultural sciences and natural resources university. the aim of this research was to evaluate effect of vermicompost (vc) on bush bean seedling e...
