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...

in order to study of hydropriming, planting depth and nitrogen split application effect on yield and yield components of double cross hybrid of corn, an experiment was carried out as factorial based on randomized complete block design (rcbd) with four replications. nitrogen split application included (400 kg/ha at sowing date, 100 kg/ha at sowing date and 300 kg/ha 25 to 50 days after sowing da...

a field investigation was conducted to evaluate the effect of n and k fertilizers on qualitative and quantitative changes of potato tubers during five months of storage. this study was carried out in three replications at five levels (0, 60, 120, 180 and 240 kg/ha) of nitrogen and three levels (0, 75 and 150 kg/ha) of potassium fertilizer during 2004-2006. measurements were recorded monthly. th...

abstract this study was conducted to determine the impacts of plastic mulch, drip irrigation method and different amount of water and their interactions on yield, water use efficiency (wue) and quality characteristic of tomato (mobile cultivar). the study was conducted in torogh agricultural research station, razavi khorasan province. the study was done during 2007-2008. experimental design was...

An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during June to December 2012 with a view to finding out the effect of variety and nitrogen fertilizer application on the growth and yield of transplant Aman rice. The experiment comprised four varieties viz. BRRI dhan33, BRRI dhan34, BRRI dhan39 and BRRI dhan46, and four levels of nitr...

This study aimed to investigate the effects of nitrogen fertilizer and a bioherbicide on Egyptian broomrape in a tomato research field at College of Agriculture, Shiraz University, Shiraz, Iran in 2014. Treatments consisted of several levels of nitrate ammonium including 0, 100, 200 and 300 kg ha-1 and a biofertilizer as the first factor and how to use the bioherbicide including soak...

In this study, the effects of nitrogen fertilizer and plant growth regulator (ethephon) application on leaf chlorophyl, stem height and diameter, stalk yield, total sugar and bioethanol of sweet sorghum were determined. Four nitrogen treatments 0, 100, 200 and 300 Kg Urea ha-1 and four ethephon concentrations 0, 800, 1000, and 1200 ppm were applied on sweet sorghum in a split plot on randomized...

With uncertainty in future irrigation water availability and regulations on nutrient application amounts, experimentally determined effects of “controllable” management strategies such as nitrogen (N), water, and their combination on crop water productivity (CWP, also known as crop water use efficiency) and actual evapotranspiration (ETa) are essential. The effects of various N application rate...
