the present study aimed at investigating the effect of different levels of nitrogen on yield and yield components of bread and durum wheat. to this end the experiment was conducted in 2010-2011 in south west of iran as split plots based on randomized complete block design with three replications. main plot included four levels of nitrogen 60, 120, 180, 240 kg.ha-1 and the sub plot included four...

in this study, the effects of different types of hand plucking were studied on green leaf yield and black tea quality. bud and a leaf, bud and two leaves, bud and three leaves and bud and four leaves were the types of hand plucking. plucking was down on chine’s hybrid tea and clone 100 in fuman tea research station. shoots were plucked in flashing period regularly during three years. green leaf...

an experiment was carried out in 2008 to investigate the effects of different irrigation regimes, and chickpea cultivars on chickpea production in the khorramabad lorestan. the experiment was split–plot in a randomized complete block design with 3 replications. supplementary irrigation at 8 levels (1-rainfed without irrigation, 2-irrigation after sowing, 3-irrigation at flowering, 4-irrigation ...

Abstract The field experiment was carried out in the experimental of Ibn Al-Bitar Preparatory Vocational School Al-Hussainiya District-Holy Karbala governorate during spring season 2021, with aim evaluating performance six maize genotypes (5018, Bahouth 106, Al-Maha, Fajr 1, Al-Furat and Sarah) under effect four levels fertilization (160 N kg.ha -1 , 160 humic acid, 320 kg. ha acid) using split...

progressive usage of medicinal plants has necessitated their mass production using the minimum amounts of chemical inputs. to find out the effects of urea and pelleted animal manure and some micronutrients on yield and its components in pumpkin, a split plot experiment based on rcbd with three replicates was conducted at the research farm of abouraihan campus, university of tehran in 2011. the ...

this research was carried out on corn in the orzuiyeh region of kerman province over two consecutive seasons (2005-6 to 2007-8). the experiment was done as a split plot with a completely randomized block design and four replications. four levels of consumed water (60%, 80%, 100% water requirement, water use based on regional custom) and three varieties (404sc, 700sc, 704sc) were the main factor...

The aim of the present investigation was to study the growth, yield and yield components of maize (Zea mays L.) single cross 704 under different levels of irrigation, plant density, and ethephon in southern Iran where this particular crop has not yet been studied in detail. A field experiment was performed in the 2004 5 growing season at the experimental farm of the College of Agriculture, Shir...

in order to investigate the effect of seed rate on seed yield and yield components of three rapeseed varieties, a split- plot experiment was conducted in randomized complete block design with four replicates during 2008-2009 at baykola agricultural research station, neka, mazandaran province. in this experiment four seed rates (5, 7, 9 and 11 kg.ha-1) as main plots, three rapeseed cultivars (hy...
