Nitrogen Content of Helleri Holly as Influenced by Ambient Temperature and Nitrogen Fertilization Rate

Growth and nitrogen content of sunflower as affected by the rate and form of nitrogen

N uptake and yield of wheat as influenced by integrated use of organic and mineral nitrogen

The effect of integrated use of mineral and organic N sources (farmyard manure, poultry manure, and Filter Cake) on yield and N uptake of wheat were assessed in biennial field experiment carried out on silty clay loam soil in Nuclear Institute for Food and Agriculture, Tarnab, Peshawar Pakistan during 2005-07. Combined dose of N provided from all sources was applied @120 kg ha-1. There were 17 ...

Yield, Leaf Mineral Content, and Quality Properties of Hayward kiwifruit as Influenced by Different Fertilization Methods

Kiwifruit requires a high quantity of nutrients that must be supplied through fertilization to obtain an optimum yield on a sustainable basis. This research was conducted to evaluate different fertilization methods including broadcast application (as control), deep placement of the fertilizer and fertigation, alone or in combination with foliar application and their effects on the yield, leaf m...

Soil Carbon Dioxide Emission as Influenced by Irrigation, Tillage, Cropping System, and Nitrogen Fertilization

Soil and crop management practices can influence CO2 emission from crop and grasslands and therefore on global warming. We examined the effects of two irrigation systems (irrigated vs. non-irrigated) and six management practices [no-till malt barley (Hordeum vulgaris L.) with 67 or 134 kg N ha (NTBFN), notill malt-barley with 0 kg N ha (NTBON), conventional-till malt barley with 67 or 134 kg N ...

Potassium and Sodium Uptake by Sugarbeets as Affected by Nitrogen Fertilization Rate, Location, and Year*

Received for Publication October 28, 1985 INTRODUCTION Fertilization of sugarbeets (Beta vulgaris L.) with potassium (K) is generally not recommended in the intermountain areas of the western United States. This is attributable to the general abundance of available K and sodium (Na) in the soils of this region, irrigation water often containing significant K and Na concentrations (7), and the l...
