A field experiment was conducted at Bangladesh Agricultural Research Institute, Gazipur during rabi (winter) season of 2008-09 to observe the efficacy of two herbicides on the yield of lentil (BARI masur-5). Paraxon, Whipsuper, Ronstar and Topstar were the herbicidal treatments applied after sowing of seeds and two leaf stage of weeds according to their mode of action. Dry weight of weed sample...

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...

Field experiments were performed to identify an effective fertilizing scheme for direct-seeding rice (DSR) fields in the Taihu Lake Basin in east China. Based on local traditions, 3 typical fertilizing schemes (FS-1, FS-2, and FS3) were evaluated, in consideration of ensuring a certain rice yield and relatively low nitrogen (N) loss. The base, seedling, tillering, jointing, and panicle fertiliz...

Drought is one of the most important factors that limits N fixation, growth and yield of soybean. 2 The aim of this study was to determine the effects of water stress, starter N application and seed inoculation on yield and yield components of soybean (cv. Williams). The experiment was conducted in 2010 at the Islamshahr town that located in 12 km of South-west of Tehran, the capital of Iran. T...

Vernonia galamensis Cass is a huge potential industrial crop with very high content of vernolic acid in the seed oil. The experiment was carried out to determine the effect of inter- and intra- row spacing on the yield and yield related traits of Vernonia galamensis Cas.The experiment was conducted for two years during 2014-2015 on experimental field of Wondo Genet Agricultural research center,...

in order to identify drought stress tolerance in rapeseed, nine commercial rapeseed cultivars (opera, karaj1, karaj2, karaj3, zarfam, okapi, talayeh, licord and modena) were evaluated under two conditions (normal and drought stress) in kangavar region in the west iran in 2014-2015 growing season. this research was carried out in a split plot experiment based on completely randomized design in f...

this experiment was conducted to evaluate the effects of different sowing densities and nitrogen fertilizer rates on quantitative and qualitative corn forage yield in an agroforestry system with orange trees. the treatments consisted of 4 nitrogen fertilizer levels of 0, 100, 200, and 300kg n/ha (allocated to main plots) and 4 sowing densities of 80000, 110000, 140000 and 170000 of corn seeds (...
