recently, increase in crop production depends on better seedling establishment, emergence rate and uniformity. thus, an experiment was carried out in a randomized complete block design with 8 fertilizer treatments and 4 replications in 2008 at sari agricultural sciences and natural resources university. the aim of this research was to evaluate effect of vermicompost (vc) on bush bean seedling e...

to study the effect of different fertilizing systems on macro and micro nutrients uptake by annual medic (medicago scutellata cv. robinson) an experiment was conducted under dry farming and irrigated conditions at two research stations (sararood dryland agricultural research institute and soil fertility research station in mahidasht) during 2009 growing season. the experimental treatments consi...

field experiment was conducted in 2008 at the research field of agricultural college of shiraz university, shiraz, iran to investigate the effects of urban waste compost (uwc), manure and chemical fertilizer on the initial growth of corn (zea mays). experimental design was split plot factorial with three replications. main plots were assigned to nitrogen (n) fertilizer (0 and 200 kg n ha-1), an...

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...

salinity tolerance is one of the most important affecting factors on agricultural production in arid and semi-arid areas. in order to study the effects of saline and fresh water irrigation with application of organic and npk fertilizers on cumin, a split plot experiment based on randomized complete block design was carried out with three replications during 2011 and 2012, at the research farm o...

aesthetic lines after osteotomies, symmetries of the middle third. It is also used for functional recovery of opening the nasal valve. The evaluation of the results of spreader graft is difficult and subjective. Measuring nasal valve angle is an objectie criteria of functional outcome, the brow tip aesthetic lines referred by Tardy and Sheen are options for aesthetic evaluation. Our common indi...

This study investigates the key factors affecting farmers’ decisions to use chemical fertilizer and/or organic in Chinese apple production. calculates partial output elasticities and of substitution between fertilizer, using a stochastic frontier production function model data for 2017–2019. Subsequently, it analyzes how different sales channels impact fertilizer. It also examines economic ince...

Field experiment was conducted to investigate the combine use of animal manure and inorganic fertilizer on growth and yield performance of vegetable cowpea. The experiment was laid out in a Randomized Complete Block Design (RCBD) with seven treatments. Poultry manure, cattle manure and goat manure were evaluated with recommended level of inorganic fertilizer for vegetable cowpea. The highest cr...

We conducted a controlled experiment to test the plant vigor and the plant stress hypotheses. The two hypotheses associate plant physiological conditions to insect feeding mode and performance. We exposed tomato, Lycopersicon esculentum, to different types of growing conditions: optimal (vigorous plants), resource based stress (water and/or nutrient deficit), and physical stress (punched hole i...
