on-farm experiments were designed to investigate the response of maize establishment and grain yield to variation in tillage systems. the tillage treatments included arara ploughing followed by zig-zag harrowing and arara ridging (t1); emcot ploughing fol-lowed by zig-zag harrowing and emcot ridging (t2); mouldboard ploughing followed by disc harrowing and mouldboard ridging (t3); disc ploughin...

abstract in order to study the effect of planting density and branch pruning on growth, yield and quality of greenhouse muskmelon, a study has been conducted using a factorial experiment in a completely randomized design with three replications and three factors, including cultivar (galia-52 and mirella), branch pruning (1 and 2 branch per plant), and plant density (2, 2.4, 2.8 and 3.6 plants p...

stevia rebaudiana bertoni is a medicinal, perennial and herbaceous plant from asteraceae family with sweet glycosides in its leaves. salinity stress is one of the important limiters in agricultural productions. salinity influences the growth and development of plant by effect on more activities in physiological and morphological characteristics. to study the effect of salinity on morphological ...

mulches bring several benefits to lettuce cultivation.a study on the lettuce ‘red rapids’ has been conducted to determine the influence of the different colored plastic mulch on its growth. the experiment consisted of five color treatments as follows; treatment 1- metallic silver (control), treatment 2- red, treatment 3- orange, treatment 4- yellow and treatment 5-green. results showed that the...

Charged particle identification at the PANDA experiment will be performed over a wide range of momenta by Čerenkov detectors. One option to identify higher momentum charged particles under small polar angles could be the use of silica aerogels as radiator. Simultaneously, an aerogel Čerenkov counter is being designed for the Kaos spectrometer at the Mainz Microtron MAMI for the discrimination b...

Plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. In this study, field experiment carried out as factorial Randomized Completely Block Design (RCBD) in 3 replications. Different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. Second factor was different plant spaces (10, 15, 20 and 25 cm). Results showed th...
