to study the effects of zabol wastewater treated with two kinds of fertilizer (manure and chemical fertilizer) application vs use of ordinary water on grain yield and yield components in corn (kosc704) a field experiment was conducted at the university of zabol, iran during 2007 growing season. the statistical plan selected was a split plot one of three replications. the treatments were compris...

A trial was conducted in a 7-year old citrus orchard of the National Horticultural Research Institute, Nigeria, to investigate the effect of different levels of organo-mineral fertilizers as it affect the economic returns of sweet orange (Citrus sinensis L. Osbeck var. Agege 1). The treatments consisted of: (1). 10 tha Poultry 1 manure (PM), (2). 15 t ha PM, (3) 20 t ha-1 PM, (4). 0.45 t ha NPK...

The thermochemical transformation of sewage sludge (SS) to biochar (SSB) allows exploring the advantages SS and reduces possible environmental risks associated with its use. Recent studies have shown that SSB is nutrient-rich may replace mineral fertilizers. However, there are still some questions be answered about residual effect on soil nutrient availability. In addition, most previous were c...

milkthistle (silybum marianum l.) is a rangeland medicinal plant growing wild in different locations in iran. in the present research work, the effect of n, p and k in their different proportions of n0p0k0, n100p100k50, n150p150k100 and n200p200k150 kgha-1 as compared with control (no fertilizer application) on the plant's growth was put to test. suc variables as plant height, no. of capit...

Intercropping Moldavian balm with mung bean is an ecological approach for improving resource productivity. A field experiment was conducted over two growing seasons (2018 and 2019) to determine the effect of fertilizer application on yield essential oil (EO) productivity intercropped bean. The had a two-factor randomized complete block design (RCBD) three replicates. first factor comprised five...

Coleus forskohlii L. is an important medicinal plant species found in tropical regions of India. Roots and tubers are used for treating a variety of purposes, including treating asthma, bronchitis, insomnia, epilepsy and angina.Due to diverse use, the species has been largely exploited from natural habitat leading to its threatened status. A field experiment was conducted to study the influence...

The current study is focuses on a sustainable agricultural ecosystem for soil fertility and human health improvement. To estimate the effects of applying organic amendments (compost, vermicompost, biochar, manure rapeseed cake) crop growth maize nutrient uptake in calcareous soil, eleven treatments were studied, which included compost (CM), cow vermicompost (CMV), pig (PMV), biochar (BCV), (BC)...

Problem statement: MSW has traditionally been dealt with thorough the practice of land filling and incineration. However, deleterious environmental impacts have promoted municipalities in Canada to recycle non-putrescible wastes and compost the putrescible ones. This study aimed at evaluating the effect of MSW compost on the growth and production of three vegetable crops (potatoes, corn and squ...

We assessed the impact of nutrient additions on greenhouse gas fluxes using dark static chambers in a microtidal and a macrotidal marsh along the coast of New Brunswick, Canada approximately monthly over a year. Both were experimentally fertilized for six years with varying levels of N and P. For unfertilized, N and NPK treatments, average yearly CO2 emissions (which represent only respiration)...

Article history: Received on: 28/02/2014 Revised on: 02/04/2014 Accepted on: 22/04/2014 Available online: 28/04/2014 Acute and sub-chronic toxicity studies of the aqueous extract of the root bark of C. sieberiana (Caesalpiniaceae), a plant used locally in Ghana for the treatment of pain, was carried out in rodents. In the acute study, a single oral dose (5000 mg/kg) of the aqueous extract of C....
