Two field trials were conducted during the 2014/2015 and 2015/2016 seasons at Aweesh Al-Hagar Village, center of Mansoura, Dakahlia Governorate, Egypt. A split-split-plot design with four replicates was used. The main plots assigned three nitrogen fertilizer levels, i.e., 165, 220, 275 kg/ha. sub-plots restricted to gibberellic acid (GA3) concentrations, 0, 80, 160, 240 mg/L, sub-sub received G...

A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...

The crop nutrition has a well-defined effect on yield and quality of forage crops. Among various essential macro nutrients, the nitrogen has a key function in improving forage yield and crude protein contents but demand of crop for nitrogen varies with the cultivars. The present study was conducted to investigate the effect of different nitrogen levels (0, 25, 50 kg ha) on forage yield and qual...

A field study on the effects of pre- and post-emergence application herbicide (pendimethalin) reproductive yield five accessions cowpea (TVu-9092, TVu-16265, TVu-16320, TVu-16323 TVu-16421) was conducted between June August, 2018. Pendimethalin applied both as early (PE EPOE) followed by hand weeding at 4 8 weeks after sowing (WAS). Number pods per plant highest in TVu-9092 treated with 0.125 k...

A field experiment was conducted at the Pulse Research Centre of Bangladesh Agricultural Research Institute, Ishurdi, Pabna during Kharif-II season of 2010 to evaluate the efficacy of five herbicides for controlling weeds associated with mungbean (BARI Mung-6). The five herbicides such were: Paraxon (27.6% WV Paraquat dichloride salt), M-clor 5G (Butaclor), Topstar 40 WP (40% Oxadiargyl), Hamme...

Trials were started in spring, summer and autumn to compare the effect of Agrotain-treated urea and standard urea, at application rates of 25, 50, 75 and 100 kg N/ha, on dairy pasture production on a commercial dairy farm in Canterbury. There were six replicates of these eight treatments, plus two control plots per replicate where no urea was applied. Each trial was mown three times at around t...
