raphanus sativus l. (radish) plants were grown in waste water irrigated area of dinapur, a suburban area in the north east of varanasi, india. soil and plant characteristics were compared between fertilized (farmyard manure (fym), npk, and fym+n) and non-amended control treatments. compared to the control, plants grown in fym and fym+n amended soil showed a decrease in concentrations of heavy m...

Tillage practices and nitrogen (N) sources are important factors affecting rice production. Few studies, however, have examined the interactions between tillage practices and N fertilizer sources on NH3 volatilization, nitrogen use efficiency (NUE), and rice grain yield. This study aimed to investigate the effects of N fertilizer sources (no N fertilizer, inorganic N fertilizer, organic N ferti...

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...

Sweet potato (Solanum tuberosum), a staple tuber crop in parts of the Sudan and Guinea savanna zone of Nigeria is known for its resistance to drought, vigorous early growth and low input requirements. Increase in population which has resulted to land shortages has led to reduction in traditional methods of maintaining soil fertility. Technologies based on combinations of organic and inorganic s...

The experiment was conducted at the Research Farm of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur during 14 August to 7 December, 2008 to study the effect of (different organic and inorganic) fertilizer management on soil properties and yield of five fine rice cultivars viz., Rajshahi swarna, Silkumul, Kataribhog, Lal pajam and Sanla....

Currently the world is moving towards organic production of crops for the discovered and envisaged advantages. Despite this, farmers are faced with the challenges of the bulkiness of organic fertilizer to be used and further gains that could be accrued from it even if sacrifice of using it is made. To be quite sure of the appropriate fertilizer type to be used in improving quality as well as th...

A pot experiment was carried out on hybrid drumstick PKM 1 added with inorganic and organic fertilisers. Seeds of hybrid Drumstick PKM1 were sown in the plastic pots in glass house condition. Single inorganic fertilizer, phosphate solubiliser and bio organic fertilizer as well as in different combinations were applied to the pots. Data revealed that plant height, fresh and dry biomass, moisture...
