Investigations were carried out to study the effect of organic farming with various sources of organic manures and their combinations on nitrogen use efficiency parameters of ADT 36 rice (Oryza sativa L.). The experiments were laid out in randomized block design (RBD) with fourteen treatments, comprising twelve treatment combinations of organic manures, one treatment with recommended dose of ch...

BACKGROUND A climate-controlled pot experiment was conducted to investigate the effects of planting alfalfa and applying organic fertilizer on the dissipation of benzo[a]pyrene from an aged contaminated agricultural soil. RESULTS Short-term planting of alfalfa inhibited the dissipation of benzo[a]pyrene from the soil by 8.9%, and organic fertilizer enhanced benzo[a]pyrene removal from the soi...

The study was conducted to determine the interactive effects of biochar application in combination with farm yard manure (FYM) and nitrogen (N) fertilizer on soil organic matter (SOM) and mineral nitrogen at Agricultural Research Farm of Khyber Pakhtunkhwa Agricultural University Peshawar in 2010-2011. Soil samples at 0-15 cm depth were collected from maize and mungbean plots at harvest stage (...

in order to study the effect of different organic fertilizers on quantitative and qualitative characteristics of fenugreek forage, an experiment was conducted based on completely randomized block design with six treatments and three replications at agricultural research station, college of agriculture, ferdowsi university of mashhad, iran, during 2006. the experimental treatments were four orga...

It has been previously argued that application of organic residues added in soils has a great impact on soil quality, grain productivity as well as greenhouse gas emissions. Substitution of chemical fertilizers has become a common practice in agricultural systems which consequently affect the greenhouse gas emissions from agricultural fields. To observe the effects of organic manures and crop r...

the study compared economic efficiency among smallholder farmers who practiced low external input technology [leit] and high external input technology [heit] agriculture in a harsh macroeconomic environment typified by inadequate fertilizer subsidy in imo state, nigeria. cross sectional data generated from 160 smallholder farmers randomly selected from 2 out of the 3 agricultural zones in imo s...

Field experiments were conducted to study the effect of organic matrix based slow release fertilizers (SRFs) on plant growth, nitrate assimilation and seed yield of Brassica juncea L. cv, pusa bold. The agro-waste materials like cow dung, clay soil, neem leaves and rice bran were mixed together in 2:2:1:1 ratio and used as organic matrix for the immobilization of chemical fertilizer nutrients w...

Farmers are increasing the use of fertilizers in chestnut, only cash crop produced mountainous areas northeastern Portugal. This calls for more studies to guide them towards a ecological intensification. The effects three controlled-release fertilizers, two that release nutrients over months (BoskGrow 20:05:20_3m, Exactyon 18:05:13_3m) and one six (Exactyon 18:05:12_6m), an organic amendment au...
