A field experiment was designed to study the effects of nitrogen (N) source and urease inhibitor N-(nbutyl) thiophosphoric triamide (NBPT) or nitrification inhibitor dicyandiamide (DCD) on nitrous oxide (N2O) emission and N use efficiency (NUE) in a sandy loam soil. Six treatments including no N fertilizer (control), N fertilizer urea alone (U), urea plus NBPT (NBPT), urea plus DCD (DCD), urea ...

Two field experiments were carried out on a private farm at Wadi El-Natrun (latitude of 30.48° N and longitude 30.50° E), Beheira Governorate, Egypt, in the 2019–2020 2020–2021 seasons, to find effect adding zeolite as soil conditioner potassium fertilizer growth, yield, quality sugar beet crop (Beta vulgaris L. var. saccharifera) grown sandy conditions. The present work included 12 treatments,...

This article describes still insufficiently known technology of pot marigold cultivation with the compost produced from organic waste processing medicinal plants. For first time application was analyzed different amounts (control – without compost, 2, 10 and 30 kg/m2) on morphological, productive qualitative parameters two varieties (Doma?i oranž Plamen Plus). During five-year period, best resu...

abstract leaving crop residues on the soil surface may significantly affect the behavior and activity of herbicides. to probe this effect, a factorial experiment in a randomized complete block design with three replications was conducted using two factors including different rates of wheat surface residue (0, 1250, 2500 and 3750 kg ha-1 ) and different rates of trifluralin (%48 ec) herbicide (7...

Nitrification inhibitors (NIs) have been used extensively to reduce nitrogen losses and increase crop nitrogen nutrition. However, information is still scant regarding the influence of NIs on nitrogen transformation, nitrous oxide (N2O) emission and nitrogen utilization in plastic-film-mulched calcareous soil under high frequency drip-fertigated condition. Therefore, a field trial was conducted...

A pot experiment was conducted in the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh to evaluate the influence of phosphorus (P) and sulphur (S) on major nutrient contents and their uptake by brinjal (cv. BARI brinjal-8) during the period from October, 2011 to May, 2012. The experiment was laid out in a completely randomized design with 12 ...

in order to study the influence of municipal solid waste compost and nitrogen fertilizer on grain and forage yield of sweet corn an experiment was conducted at marvdasht during 2009. the experiment was arranged in split plots based on randomized complete block design with two factors and three replications. main plot included 5 levels of nitrogen fertilizer (100, 150, 200, 250, 300 kg n ha-1) a...
