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...

The growth of the human population is causing an exponential increase in need for food. Fertilizers are one most important elements to meet this increased demand and ensure global food security. Many enhanced efficiency fertilizers, such as controlled-release fertilizers (CRFs) have been developed. Although these offer many advantages over prior generations, their high cost production well unfa...

Microbial biomass nitrogen and carbon were studied in long-term field experiments with continuous cultivation of silage maize and with crop rotation. a positive effect of organic fertilizers on the microbial biomass nitrogen and the carbon content in soil was observed. Statistically significant effect of organic fertilizers on the higher content of microbial biomass C and n was established in t...

There seems to be conflicting information about foliar fertilizers and their timing of application to cotton. Much of the confusion lies in the variety of fertilizer products available. A cotton fanner now has a choice of applying foliar fertilizers (according to fertilizer labels) beginning at the first true leaf stage and continuing until defoliation. This newsletter will focus on available i...

In recent years, excessive use of chemical fertilizers and lack of organic fertilizers caused to reduce the rate of soil organic matter in Iran. The increased use of chemical fertilizers in agriculture causes environmental problems such as soil physical degradation and soil nutrient imbalances. This study was conducted to investigate the effects of foliar and soil applications of humic acid on ...

Polymer-coated controlled-release fertilizers (PCFs) are the most widely used fertilizers in the production of container-grown nursery plants. The duration and magnitude of PCF nutrient release varies with product and this variation can significantly affect plant growth. Three experiments were conducted to determine the long-term nutrient release patterns of three PCFs (each with a rated longev...

Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertili...
