katoul is a new soybeam cultivar originated from a genotype named d.p.x.3589 imported from the united states of american in 1990. this genotype was examined together with other soybean genotypes and check cultivars in different preliminary and advanced yield traits in gorgan and other research stations during 1999-2002. the mean seed yield of d.p.x.3589 in all these experiments was 3333 kgha-1 ...

estimation of optimum fertilizer rates is needed because of growing economic and environmental concerns. optimum fertilizer rates can be determined by fitting statistical models to yield data collected from n fertilizer experiments. the main goal of this research was to compare and evaluate quadratic, square root, mitscherlich, rectangular hyperbola, linear plus plateau and quadratic plus plate...

in order to study the effects of different irrigation system and different amounts of nitrogen fertilizer on yield and quality of sugar beet, an experiment was conducted at ekbatan research station, hamedan during 2005-2006 as split plot based on randomized complete block design  with three replications. the main plots were irrigation systems (furrow, sprinkler and drip irrigation) and subplots...

A parameterised Boolean equation system (PBES) is a set of equations that defines sets satisfying the equations as the least and/or greatest fixed-points. Thus this system is regarded as a declarative program defining predicates, where a program execution returns whether a given ground atomic formula holds or not. The program execution corresponds to the membership problem of PBESs, which is ho...

The excessive use of fertilizer has resulted in serious environmental degradation and a high health cost China. Understanding the reasons for overuse is critical to sustainable development Chinese agriculture, large-scale operation considered as one measures deal with use. Under premise fully considering resource endowment heterogeneity farmers small-scale production management, different decis...

The symbolic manipulation program Schoonschip is being made freely available for a number of computers with Motorola 680x0 cpu’s. It can run on machines with relatively modest memory and disk resources, and is designed to run as fast as possible given the host constraints. Memory and disk utilization can be adapted to tune performance. Recently added capabilities include a system for efficient ...

Min introduces the type form (of object-formulae) and the infix constant −→ (for objectimplication). The constant [[ ]] maps form to the predefined type prop of meta-logic propositions. The proposition [[P ]] should be read as “the formula P is true”; we usually distinguish object-level formulae (form) from meta-level formulae (prop). In practice the brackets can be dropped; parser and pretty-p...
