Nitrogen fertilization of irrigated soybean

Effect of nitrogen fertilization on yield,protein and amino acids of irrigated mexipak wheat

Growth, Yield and Nitrate Accumulation of Irrigated Carrot and Okra in Response to Nitrogen Fertilization

A randomized block experiment conducted on Sultanpur silt loam evaluated the N effects on growth and nitrate accumulation of okra (Hibiscus esculents L. cv. Sabz pari) and carrot (Daucus carota L. cv. T29). Treatments consisted of a control, 100, 150 and 200 kg N ha. Significantly higher yields of carrot and okra were recorded at 150 kg N ha. Nitrate concentration in both increased (> 35 to 200...

Efficiency of nitrogen fertilization in spring wheat

An assessment of the nitrogen fertilization efficiency should not only include quantitativeand qualitative yield changes, but also an analysis of formation some indicators such as: Nharvest index (NHI), N use efficiency (NUE), N utilization efficiency (NUtE), N agronomicefficiency (NAE), N physiological efficiency (NPE) and N apparent recovery fraction (NRF).The objective of the study was the e...

Effect of rhizobium and nitrogen on soybean

Irrigation and Nitrogen Fertilization Influences on Properties of Soybean (glycine Max (l.) Merr.) Varieties

Soybean is an important industrial crop in Croatia and in the last ten years (2000-2009) mean soybean harvested area was 45888 ha (from 35789 to 62810 ha) with average seed yield 2.0 t ha-1 (Central Croatian Bureau of Statistic, 2010). Seed yields of soybean varied in close connection with amount and distribution of precipitation during the vegetation period (Vučić and Bošnjak, 1980; Bošnjak, 2...
