one of the important aspects of the medicinal plants production is using less chemical inputs. it could be effective for increasing of production and environmental purposes. in order to investigate the effects of application time of integrated chemical fertilizer with cattle manure on growth, yield and yield components of black cumin (nigella sativa l.), an experiment was conducted based on a r...

determining the best mixture of sorghum and fenugreek intercropping defines the best forage quality in medicinal forage production. this project was conducted to evaluate the effect of biological, chemical and integrated fertilizing systems on forage quantity and quality in sorghum and fenugreek intercropping. the experimental treatments were arranged as split plots based on randomized block de...

Two field experiments were carried out during the summer seasons of 2000 and 2001, at the Experimental station Farm, Faculty of Agriculture, Alexandria University, at Abies, to investigate the response of potato plants cv. Alpha, to two biofertilizer types (Nitrobein and Halex-2) under four varying percentages NPK; 25%, 50%, 75% and100% from the commercial recommended rates (180-60-96 Kg N-P-K ...

Background: Rice is one of the staple crops in African continent for its ability to give maximum yields which can help achieve food security under sustainable development goals (SDGs); those effects, incessant use inorganic fertilizer has been employed proved have devastating effect environment and ecosystem at large. Therefore, thirst an alternative method ensure bumper production rice cannot ...

in order to study the effects of different levels of drought stress and plant growth promoting rhizobacteria on the germination indices of seeds harvested from wheat (tritium aestivum l.) cv. sayonz in the field treated with different levels of nitrogen, in controlled conditions, a factorial layout based on completely randomized design with three replications, was conducted. treatments included...

The growth and quality of medicinal plants are greatly affected by environmental stress, with over half the world’s agricultural land facing water shortages. This research was conducted two seasons in 2018 2019 aimed to investigate influence varying irrigation intervals partial replacement mineral fertilizers biofertilizer (yeast) on growth, yield, essential oil content lemongrass. study also l...

in order to investigate the effect of different levels of biological fertilizers on potato performance (cv. marfona), an experiment was carried out as strip plot based on rcb design with 3 replications in 2011 at isfahan. treatments included nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and nitroxin+ phosphate at 4 levels (0+0: control, 20+100, 30+150 and 50+200...

<p>The use of N<sub>2</sub>-fixing bacteria and growth hormone-producing rhizobacteria delivers nitrogen, enhances nutrients absorption by plants, reduces the usage inorganic fertilizers. Implementing biofertilizer in hydroponic system as a means to reduce application synthetic nutrient is recently interest due economic, food safety, sustainability factors. This study determin...

A field experiment was conducted to study the effect of a Pseudomonas fluorescens-based biofertilizer on sweet potato (Ipomoea batatas (L) Lam) yield. The application by immersion cuttings before sowing for 0, 5, 10 and 15 minutes with combination doses 50 100% NPK mineral fertilizer in randomized block design three replications (12 treatments-combinations). During harvest (130 days after plant...

The study aims to define the potential and technological aspects of digestate treatment for its application as a biofertilizer. Life cycle assessment methodology was used in terms quality management. nutrients, organic carbon, useful microelements allows consideration mineral fertilizer substitute soil improver. valorization requires management control. Based on research focus, successful post-...
