Beneficial microorganisms are found in biofertilizers, which can assist boosting the soil's availability of N, P, and K promote plant growth. This study aims to ascertain impact optimal combination biofertilizer fertilizers for sweet corn yields, total bacteria, humic acid, C-organic yields. With 1 control treatment, 2 doses fertilizer, 6 combinations fertilizer biofertilizer, method used Rando...
In line with sustainable agriculture development, an experiment was conducted including tillage as the main factor in two conventional systems (plowing and mixing fertilizer with soil) and no tillage (leaving residuals of green manure and direct corn sowing). The fertilizer resources were T0: control, T1: barley green manure without chemical and manure fertilizers, T2: barley green manure with ...
In order to evaluation the effects of soil organic matter and biofertilizer on chickpea quality and biological nitrogen fixation, field experiments were carried out in 2007 and 2008 growing seasons. In this research the effects of different strategies for soil fertilization were investigated on grain yield and yield component, minerals, organic compounds and cooking time of chickpea. Experiment...
Alkaline soils with low buffering capacity are susceptible to amendments such as biochar or biofertilizers, which could drastically alter their pH. For that, this study aimed evaluate the effectiveness of a and biofertilizer addition improve soil characteristics use nutrients reduce doses chemical fertilizer. we measured initial effect on characteristics. Then, changes produced by cultivated so...
Experiment was conducted during 2007 growing seasons at the Field of College of Agriculture, Tarbiat Modares University, Tehran Province, Iran to study the effect of biofertilizers (Azosporillum and Azotobacter), nitrogen fertilizer (N) and farmyard manure (FYM) in various rates on the grain and biological yield, seed protein content as well as seed oil content and fatty acid composition in sun...
Onion (Allium Ascalonicum L) are one of the leading horticultural commodities that have economic value. In cultivation, Fusarium wilt disease is often damaged caused by fungus oxysporum. This study aimed to examine effect biofertilizer application on fusarium disease, growth and yield onion. The treatments tested were Bion-up biofertilizer, KIBRT, Biostimulant, Azoto-Tricho, anthracol fungicide...
Sustainable agriculture can increase the efficiency of resource utilization, provide longer productivity and create a balance in the environment. A field experiment was conducted to study the use of organic and chemical fertilizers on biomass, essential oil content and essential oil yield as well as chemical compositions of Dracocephalum polychaetum Burnm in the first and second cutting. The tr...
in order to investigation the effects of different combination and amount of chemical, biological and organic manure in present of water absorbent materials on some phenological, morphological and yield of soybean, a field study was carried out gorgan region climate conditions in a factorial experiment based on randomized complete block design with three replications. in this experiment two lev...
This study aimed to understand the effect of commercial seaweed extract as a biofertilizer, named True-Algae-Max (TAM®), on yield, nutritional, antioxidant, and cytotoxic activity Eruca vesicaria. Three concentrations TAM® (5, 10, 15%) were studied by foliar spray over two cultivation years (2016 2017) without any chemical fertilizer, along with control consisting synthetic nitrogen, phosphorus...
Bio-fertilizers are naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants by providing growth promotion. This investigation was aimed at determining the effect of Nitroxin bio-fertilizer application on growth, inoculation and yield production of corn hybrids. An experiment was conducted as split plot on the basis of randomized complete block design with fou...
