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 ...
متن کاملBark Yields of 11-year-old Loblolly Pine as Influenced by Competition Control and Fertilization
Bolts cut from 11-year-old loblolly pines (Pinus taeda L.) were measured to determine the effects of applications of fertilizer and competition control treatments on the amount of pine bark produced. Bark thickness at breast height was not significantly affected by any of the treatments. Regression analysis showed that the dry weight of bark per unit surface area of the bolt increased as the vo...
متن کاملlight attenuation in a W - year - old loblolly pine stand as influenced by fertilization and irrigation
We examined empirical and simulated’ estimates of canopy light attenuation at SETRES (Southeast Tree Research and Education Site). a 2x2 factorial study of water and nutrients. Fertilized plots had signiticantly lower under-canopy PAR transmittance (T,) when compared to non-fertilized plots. Light interception efftciency. as measured by the canopy cosine-corrected light extinction coefficient. ...
متن کاملMineral nutrition, resin flow and phloem phytochemistry in loblolly pine.
Southern pine beetles and associated pathogenic fungi represent the largest biotic threat to pine forests in the southeastern USA. The two primary defensive mechanisms of the tree to the beetle-fungal complex are the primary oleoresin flow and the concentrations of preformed and induced secondary compounds. We compared oleoresin flow and concentrations of phloem nutrients, soluble sugars, starc...
متن کاملYield, 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...
