Current biofuel feedstock crops such as corn lead to large environmental losses of N through nitrate leaching and NO emissions; second-generation cellulosic crops have the potential to reduce these N losses. We measured N losses and cycling in establishing miscanthus (), switchgrass ( L. fertilized with 56 kg N ha yr), and mixed prairie, along with a corn ( L.)-corn-soybean [ (L.) Merr.] rotati...

Tujuan dalam penelitian untuk menekan penggunaan pupuk N-P-K anorganik mendapatkan dosis p...

The study was undertaken to determine the dissipation kinetics of trifloxystrobin and tebuconazole residues on tomato under field conditions and thereby to ensure consumer safety. Three applications of a combination formulation, Nativo 75 WG (trifloxystrobin 25% + tebuconazole 50%) were made @ 350 and 700 g ha-1 at 7 days intervals. Tomato samples were collected at 0 (1 hr), 1, 3, 5, 7, 10 and ...
