Growing Potatoes with Slow-release Nitrogen Fertilizer
Nitrogen management practices have an effect on crop yields but they can also have a negative impact on the environment. Practices such as banding fertilizer and/or split-applying total nitrogen needs per acre offer a more efficient use of nitrogen by significantly reducing nitrate leaching potential. Heavy rains occurring when plants are small and nitrogen demands are low can also increase nit...
متن کاملEffect of Seedling Age and Nitrogen Fertilizer on Growth, Chlorophyll Content, Yield and Economics of Hybrid Rice (Oryza sativa L.)
A field experiment was conducted during kharif season of 2010 and 2011 to investigate the optimization of nitrogen levels under different age of seedlings transplanted on growth, chlorophyll content, yield and economics of hybrid rice. Fifteen treatment combinations consisted of three levels of seedlings age (10, 20 and 30 days) and five levels of nitrogen viz. N0, N50, N100, N150 and N200 kg h...
متن کاملResponse of Marigold Flower Yield and Yield Components to Water Deficit Stress and Nitrogen Fertilizer
In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...
متن کاملAssessment of the Slow-Release Nitrogen Foliar Fertilizer Nitamin® in Comparison to Foliar Urea and Soil-Applied Nitrogen to the Yield of Field-Grown Cotton (Gossypium Hirsutum, L.)
Effective nitrogen (N) management in cotton production is essential in order to achieve proper growth and development. However, soil-incorporated N can undergo a series of chemical conversions along with numerous loss mechanisms (leaching, volatilization and denitrification) that can make N unavailable to the plant. In addition, soil-incorporated N has faced much scrutiny over the years for its...
متن کاملnitrogen fertilizer optimization and its response to the growth and yield of lowland rice
abstract lowland rice (oryza sativa l.) in south asia is under stress, as nitrogen removals by crops are higher than their replenishment through fertilizers. limited information is available on optimizing nitrogen dose in lowland rice to turn out higher yield. the present investigation aimed to optimize nitrogen fertilization and it’s response to the growth and yield of lowland rice. we evaluat...
