The problems of low soil fertility resulting from continuous monocropping, crop residue removal and limited fertilizer use represent key challenges to produce surplus food for the ever increasing population of Ethiopia. However, the practices of crop rotation and integrated sources of fertilizer uses could potentially improve soil fertility and productivity. In 2012 and 2014, soybean with diffe...

in order to investigate the possibility of using organic fertilizers in tobacco floating nursery, an experiment was conducted at tobacco research institute of urmia in 2010. the experiment was done as factorial trail based on randomized complete block design (crbd) with four replications. the levels of first factor were disinfected poultry manure, disinfected pigeon manure, a complete fertilize...

Continuous intensification of agriculture with inorganic fertilizers causes a decrease in soil quality; grumusol has high clay content and low organic matter. This study aims to examine the effect liquid fertilizer on flowering, shallot yield, ability improve quality. The research used completely randomized block design one factor, namely fertilization six levels: 100% fertilizer; 75% 25% 50% s...

in order to study the effects of organic and inorganic nitrogen sources on quantitative and qualitative characteristics of three winter rapeseed cultivars, a field experiment was carried out as factorial arrangement in complete block design with three replications in agricultural and natural resources research center of markazi province, arak, during 2008-2009 growing season. three rapeseed cul...

Boosting crop productivity can be attained through the application of inorganic fertilizer; however, safeguarding environment for future generations is overbearing especially continuous increase in world population. Sustainable might judicious use both organic and fertilizers. The substitution parts fertilizers with fertilizer could maintain sustain soil improve productivity. This paper has rev...

ABSTRACT- Declining land productivity associated with decreasing soil organic carbon and nutrients is a significant issue in monoculture production. The field experiment with different rates of fertilizer systems (60 kg ha-1 N + 100 kg ha-1 P, 300 kg ha-1 Bio-organic (organic fertilizer), 3 kg ha-1 Bioumik (biofertilizer), 30 kg ha-1  N + 50 kg ha-1 P + 150 kg ha-1 Bio-organic fertilizer and 30...
