In order to study the effect of different levels of the manure and foliar application of Zn and Mn fertilizers on the quantitative and qualitative yield of soybeans (var. Williams), a factorial experiment was conducted in a randomized complete block design with three replications in 2012. Treatments involved three levels of fertilizer: manure (zero as control; six and 12 t/ha), two lev...

the main reasons for the fixation of some elements and consequently nutrient deficiencies, especially phosphorus, iron and zinc, are high levels of calcium (calcareous soils) and soil ph. two sulfur fertilizers (sulfur alone and sulfur + organic material + thiobacillus spp.) with two rates (2 and 4 kg sulfur/tree) were used to decrease soil ph and availability of p, fe and zn in apple trees dur...

We study optimization methods for source-initiated energyefficient broadcast in all-wireless networks. The minimum energy broadcast (MEB) problem in wireless networks proved to be NP-complete [1,4]. Past studies on MEB problem [1,2,5,8,9] focus on deterministic optimization to construct energy-efficient broadcast tree. In this paper, we present a probabilistic optimization approach, the Randomi...

Topology Broadcast based on Reverse-Path Forwarding (TBRPF) is a proactive, link-state routing protocol designed for use in mobile ad-hoc networks. TBRPF has two modes: full topology (FT) and partial topology (PT). TBRPF-FT uses the concept of reverse-path forwarding to reliably and efficiently broadcast each topology update in the reverse direction along the dynamically changing broadcast tree...

Poorly drained claypan soils can increase the importance of tillage and N management for corn (Zea mays L.) production. Field research in 2008, 2009 and 2010 (high rainfall years) near Novelty, MO (40° 1' N, 92° 11' W) sought to determine the effect of polymer-coated urea (PCU) placement [strip-tillage (ST) deep banded and no-till (NT) broadcast] and application timing (fall, early preplant...

In this paper, we study a broadcast problem in directed trees. This problem is motivated by the task of implementing broadcast and multicast requests in computer systems with networks that utilize circuit routing schemes such as wormhole routing or virtual cut through routing as opposed to store and forward routing. Examples of such systems include the Intel Paragon and the NCUBE-2. The problem...

Nutritional management is an important factor in the success of crop production. In order to evaluate different level of nitrogen, potassium and zinc fertilizers on agro physiological characteristics of green bean a field experiment was conducted as split-plot based randomized complete block design in three replications, in Varamin university field research during 2011. The main plot included u...
