Considering the importance of organic fertilizers application and the necessity of minimizing the use of inorganic fertilizers, this experiment was conducted in order to study the possibility of replacing vermicompost and poultry manure instead of chemical fertilizers in the production of two improved chickpea cultivars under dryland conditions. The experiment was laid out in a factorial arrang...
Common purslane is a warm season plant which had a lot of medicinal properties. An experiment was conducted as a split plot design arranged in completely randomized block design with three replications in the research field of Agricultural Sciences and Natural Resources University of Khuzestan during 2015-2016. In this experiment, the main plots consisted of four levels of irrigation intervals...
Effects of chemical fertilizers (urea, super phosphate and potash) on toxicities of two carbamate insecticides, carbaryl and carbofuran, individually to the N2-fixing cyanobacterium, Cylindrospermum sp. were studied in vitro at partially lethal levels (below highest permissive concentrations) of each insecticide. The average number of vegetative cells between two polar heterocysts was 16.3 in c...
Medical plant Purslane contain large amounts of material with extraordinary health benefits of Omega-3 fatty acids and monounsaturated fatty unique combination of vitamin C, beneficial effects on the circulatory system and the heart. Therefore, research into application attract moisture substance and organic fertilizer and chemical on yield of purslane (Portulaca oleracea L.) In Ahwaz conditio...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
management of soil fertility via biological fertilizers inoculation is one of the most important components based on sustainable agriculture. in order to investigate the effects of biological and chemical fertilizers on yield and some morphological traits of forage yield sorghum, a field experiment was conducted as factorial based on randomized complete block design with three replications at a...
The yield, nutrient uptake and cost efficacy of Chlorophytum. borivillianum were studied using dual inoculation with AM fungi (Glomus fasciculatum) and Azotobacter chroococcum. The experiment was conducted for two consecutive years with two levels of chemical fertilizers as F1(N-P-K : 24-24-32 kg ha) and F2 (N-P-K : 30-30-40 kg ha). Inoculation of bioinoculants encouraged results; the fresh tub...
Nowadays, knowing that chemical fertilizers have distinct pollution effects on environmental quality parameters, the organic fertilizers represent a suitable and safe alternative, at least for landscape applications. However, the response of many ornamental and landscape plants, including Sweet William, to different chemical and organic fertilizers are not well known. Thus, this factorial exper...
nterest in organic fertilizers is growing in the greenhouse industry, but experience and trials are not keeping up. There is little information available on how well the new types of fertilizers provide nutrition for plants compared to traditional water-soluble chemical fertilizers. The most widely available “organic” fertilizers for application like traditional water-soluble fertilizers are fi...
An experiment was conducted to find out the effect of INM on vegetative growth, flowering and fruiting of Andrographis paniculata. The experiment was followed in a randomized block design with 8 treatments. The different treatments were T1no treatment, T2vermicompost, T3-biofertilizers, T4-chemical fertilizers, T5biofertilizers + vermicompost, T6biofertilizers + chemical fertilizers, T7chemical...
