Pot experiment was conducted to study the alternate and fixed partial root zone drying on irrigation water use efficiency phosphorus absorption of corn (Zea mays L.) in a gypsiferous soil during spring growing season. The included three techniques, which were conventional (C1), alternating root-zone (APRD) (FPRD), levels phosphate fertilizer application (40, 80, 120 Kg h-1), for stages plant gr...

one of the new techniques applied in the drying process of food stuffs that can increase the drying rate, enhanced the product quality, and while decresing the costs of processing is an application of infrared radiational energy. in this study the thin layer drying process of button mushroom was modeled through an infrared applied drying method. drying experiments with sliced samples of button ...

Abstract To study the effect of water stress in rapeseed cultivars at the seedling stage, 10 rapeseed cultivars were evaluated at three irrigation levels [normal irrigation (control) and irrigation after depletion of 60 and 85% of available soil water]. Analysis of variance showed considerable variation among cultivars. Water stress reduced all of the studied morphological characteristics, espe...

the present research surveyed the effect of five factors including: microwaves power, air temperatures and its flow rates, microwaving time onset and amount of substances on the requested time and energy for combined fluidized bed- microwaves drying of black raspberry into 50% dry base wet content. response surface methodology and central composite was used as experimental design. multiple line...

common drying systems, including hot air convection, infrared, vacuum and ir-convective were employed to investigate and analyze the drying process of mulberry fruits. to evaluate the effect of pretreatment on the drying phenomenon, samples were pretreated by being subjected to: microwaves, chemical preparation, mechanical as well as blanching approaches. results revealed that the microwave pre...

in order to the study of the salinity effects on seed germination and effecting parameter of fennel (foeniculum vulgare) was conducted a factorial experiment in a completely randomized design with two factors and three replications. factor a was 10 ecotypes, including; sardasht, saghghez, kerman, tabriz,sabzevar, rome, khusf, bojnoord, mashhad and shabestar and factor b was five concentrations ...
