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...

Nutrient management for production, profit, and environmental protection: Striking the balance Strategies to manage nutrients in crop production were first designed to maximize crop yields, an objective that became increasingly possible with the development of inorganic fertilizers during the past century. Later, as economic analysis of farm profitability became more sophisticated, strategies s...
A common crop rotation in the west Iran is wheat-fallow-corn. The fallow period after wheat harvest (during fall and winter) can lead to soil erosion, nutrient losses (e.g. nitrate leaching) and offsite movement of pesticides. This period is an ideal time to establish a cover crop. In order to investigate the effects of different autumn-bseeded cover crops on subsequent irrigated corn response ...
