in order to evaluate the effects of foliar application of methanol and irrigation intervals on yield and yield components of chickpea cultivars a factorial experiment as split plots based on randomized complete block design with three replications was conducted in spring 2008 at the agricultural research station of ferdowsi university of mashhad. the treatments were 10 and 20 irrigation interva...

Eggplant shoot and fruit borer (ESFB), Leucinodes orbonalis G. is a key pest of eggplant, Solanum melongena L. Organophosphates (OP) having high toxicity and persistence are used to control the pests in many developing countries, despite availability of new insecticides with better qualities. Field evaluation of thiacloprid and indoxacarb were carried out against ESFB, with an OP insecticide, m...

A laboratory experiment has been conducted to investigate the ecological toxicity of flubendiamide and spinosad at their recommended field rates and higher rates (1.0, 2.5, 5.0, 7.5, 10.0 kg ha-1) on cellulase, invertase and amylase in black and red clay soils after 10, 20, 30 and 40-day exposure under controlled conditions in groundnut (Arachis hypogaea L.) soils of Anantapur District, Andhra ...

Efficacy of three rates of aldicarb for control of Hoplolaimus columbus was evaluated on highly tolerant ('Foster'), moderately tolerant ('Coker 368'), and highly susceptible ('Braxton') soybean cultivars planted on 28 June 1985. Average yields of the nontreated cultivars were 557 kg/ha for Braxton, 1,309 kg/ha for Coker 368, and 1,682 kg/ha for Foster. Yield differences were significant. Aldic...

Selenium (Se) was applied to perennial ryegrass (Lolium perenne) and subterranean clover (Trifolium subterranean) pasture as a fertilizer to determine the effect of Se form and concentration on Se accumulation in subsequent forage growth. Treatments were a no Se control, 0.6 kg/ ha Se as sodium selenate, and 0.6, 1.1, and 2.2 kg/ha Se as sodium selenite, all applied to pasture plots with low so...

This study was conducted to measure the effects of slurry application method, swine growth stage, and flow rate on runoff nutrient transport. Swine slurry was obtained from production units containing grower pigs, finisher pigs, or sows and gilts. The swine slurry was applied using broadcast, disk, or injection methods at a rate required to meet annual nitrogen requirements for corn. Three 30 m...

The effect of nitrogen fertilization on root length (RL) distribution of winter wheat (Triticum aestivum L.) was investigated. The study was conducted in Prague-Ruzyne on clay loam Chernozemic soil in the years 1996–2003. Two (N0, N1) and three (N0, N1, N2) treatments, unfertilized (N0), fertilized with 100 kg (N1) and 200 kg N/ha (N2) were studied in 1996–2000 and 2001–2003, respectively. Nitr...

A field experiment was conducted to study the integrated weed management in groundnut (Arachis hypogaea L.) for consecutive three kharif seasons in 2010, 2011 and 2012 at Breeder Seed Production Farm of Orissa University of Agriculture and Technology, Bhubaneswar with 7 weed management treatments in four replications. Weed free check (two hand weeding at 20 and 40 DAS and manually uprooting of ...

Watersheds using surface water for irrigation often return a portion of the water to a water body. This irrigation return flow often includes sediment and nutrients that reduce the quality of the receiving water body. Research in the 82,000-ha Upper Snake Rock (USR) watershed from 2005 to 2008 showed that, on average, water diverted from the Snake River annually supplied 547 kg ha of total susp...
