The object of this experiment was to determine the response of peanut when planting in single or twin row patterns by strip tillage or no tillage methods. During 1997 and 1998 the peanut cultivars "Georgia Green" and "Georgia Runner" or "Georgia Green" and "Georgia Bold" (Arachis hypogaea L.) were planted in 9.5 or 9.0 inch twin row patterns versus 36 inch single rows at the same seeding rate (...

in order to investigate lentil response to application times and amounts of zinc, an experiment was arranged as factorial based on randomized complete block design with four replications on farm research of gonbad higher education center during 2008-2009. treatments were application times (before flowering and beginning of pod setting) and application rates (0, 0.5, 1, 1.5 and 2 liter per hecta...

in order to apply suitable methods for sugar beet seed sowing and determine the relation between yield and growth parameters in saline soils, two salt tolerant progeny lines were sown by five methods for two years (1995 and 1996) using a split plot design. growth parameters such as leaf area index, crop growth rate, total dry weight and relative growth rat were analysed. ph and ec of the soil a...

 Homand Absard Rangeland Research Station is located 70 km northeast of tehran and 15 km southeast of Damavand with an altitude of 1972 m a.s.l., an average annual rainfall of 333 mm,  and a cold semi-steppe climate. In order to compare  the seed production of Vicia villosa under different cultivation seasons and methods, the seeds were initially collected from natural habitats similar to the m...

The new Early Soybean Production System (ESPS), developed in the Midsouth USA, including the Mississippi delta, resulted in higher yield under irrigated and non-irrigated conditions. However, information on the effects of the agricultural practices such as row-type (RT: twin- vs. single-row), row-spacing, (RS), seeding rate (SR), soil-type (ST) on seed nutrition under the ESPS environment in th...

this experiment was conducted for estimating the effect of row spacing and plant density on soil moisture change, wheat yield and water use efficiency in rainfed condition, using a three replicated randomized complete block design with factorial arrangement at gorgan university of agricultural sciences and natural resources farm in anbare-ololum region in 2008-2009. the treatments that used wer...

Abstract. Let Mn;m be the set of n-by-m matrices with entries inthe field of real numbers. A matrix R in Mn = Mn;n is a generalizedrow substochastic matrix (g-row substochastic, for short) if Re e, where e = (1; 1; : : : ; 1)t. For X; Y 2 Mn;m, X is said to besgut-majorized by Y (denoted by X sgut Y ) if there exists ann-by-n upper triangular g-row substochastic matrix R such thatX = RY . This ...
