The field experiment was carried out during Rabi season of 2022 at the Crop Research Farm, Department Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology And Sciences, Prayagraj (U.P.) India, to study effect bio- fertilizers and zinc sulphate on growth yield Maize. treatments consist Bio-fertilizers PSB, Azotobacter, PSB + Azotobacter ZnSO4 (20, 25, 30 kg...

The efficacy of sustained release Altosid sand granules to control adult Aedes taeniorhynchus and Culex quinquefasciatus emergence was investigated. Sand granules applied at a 7-day preflood application rate of 5.6 kg/ha controlled 99% of the Ae. taeniorhynchus emergence in saltwater plots for 44 days posttreatment and 35% of Cx. quinquefasciatus in freshwater plots. A 5.6 kg/ha rate controlled...

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...

Pyrene removal by polycation-montmorillonite (MMT) composites and granulated activated carbon (GAC) in the presence of humic acid (HA) was examined. Pyrene, HA, and sorbent interactions were characterized by FTIR, fluorescence and zeta measurements, adsorption, and column filtration experiments. Pyrene binding coefficients to the macromolecules were in the order of PVPcoS (poly-4-vinylpiridine-...

An experiment was carried out during two subsequent years, i.e., 2009-10 and 2010-11 to study the influence of Azotobacter, vermicompost on growth, flowering, yield and quality of strawberry cv. Chandler. There were nine treatments comprising two levels each of Azotobacter (6 and 7 kg/ha) and vermicompost (20 and 30 t/ ha) and their combinations along with one control, replicated thrice in rand...

to evaluate the effect of time and level of nitrogen application on quantity and quality of two carrot varieties, an experiment was carried out in the framework of a 4×3×2 factorial and based upon a randomized complete block design of three replications. the levels of 25, 50, 75 and 100 kg / ha of nitrogen fertilizer were investigated within 3 applied times, namely: simultaneous with bed prepar...

Humic acid (HA) can supplement the chemical fertilizers to reduce the input cost of agricultural production. Field experiments on increasing cotton [Gossipium hirsutum L, cv. CIM-473] crop yield through HA were conducted in salt-affected soil of Kohat division, NWFP, Pakistan, during Kharif 2005 at two sites being irrigated with tube-well saline waters. Four levels of humic acid (0, 0.5, 1.0 an...

An accurate and management sensitive simulation model for tile-drained Midwestern soils is needed to optimize the use of agricultural management practices (e.g., winter cover crops) to reduce nitrate leaching without adversely affecting corn yield. Our objectives were to enhance the Agricultural Production Systems Simulator (APSIM) for tile drainage, test the modified model for several manageme...

Grazing management is a key element determining herbage production and grazing efficiency. This study measured herbage accumulation and grazing efficiency in Mombaça grass pastures (Panicum maximum cv. Mombaça) subjected to intermittent defoliation managements. Treatments were combinations of 2 rest periods (grazing at either 95 or 100% canopy light interception — LI) and 2 grazing intensities ...
