The aim of this study was to investigate the effect  of irrigation period on the quality and quantity of yield and some morphological and physiological traits of three multigerm sugar beet genotypes named BP Mashhad, BP Karaj and 191. The experiment was in a split  plot  based on randomized complete block  design , carried out  at Motahari Research station of Sugar beet Seed Research Institute ...

the effects of traffic frequency and skid trail slope on dry bulk density, litter mass and rutting are examined. treatments included a combination of four different traffic frequencies (3, 7, 14, and 20 passes of a rubber skidder) and three levels of slope ( 20%.) the results showed that dry bulk density, rut depth and soil displacement increased with the increase of traffic frequency and slope...

Objective: A field experiment was conducted in order to study the effect of phosphorus and manure application on agronomic performance and seed yield of groundnut. Methods: Factorial combination of two groundnut varieties (‘Werer 962’ and ‘Oldhale’), Three rates of phosphorus (0, 90 and 180 kg P2O5 ha-1) and three rates of manur...

According to Simons (1997), schools need ‘process-oriented instruction’ to let pupils learn in a new learning way. He defines this instruction as: “(...) focussing on the further development of the processes of thinking, learning and selfregulation integrated in regular domain-specific instruction (...) it also tries to hand over responsibility for learning and teaching to the learner gradually...

We have developed anew technique for the application of microtracer technology to the on-site assessment of microingredient uniformity in diets for feedlot cattle. The influence of dietary forage (12 vs 24%) and molasses levels (6, 12, 18, and 24%) on the efficiency of recovery of microtracer (33 g/ton) using this new technique was compared with that of chromic oxide (87.4 g/ton) and laidlomyci...

An experiment was conducted to study the effects of lamtoro (Leucaena leucocephala) leaf supplementation in fermented kumpai grass (Hymenachne amplexia calis) based rations on the productivity of Bali cattle. Variables measured were dry matter and organic matter intakes, nutrient digestibility (dry matter, organic matter, crude protein, and crude fiber), body weight gain, and feed efficiency. T...
