Abstract :

Experiment was conducted to study the effect of soil preparation methods and the efficiency of herbicides in weed control and yield of sugarcane. Experimental design was a split plot in RCB with 3 replications. The main plot was land preparation: primary tillage 1 time, primary tillage 1 time and secondary 1 time and primary tillage 1 time and secondary 2 times. Sub plot was using pre-emergenc ...

Abstract :

This study was conducted to establish standard fresh weight data about the minimum amount of occurred weeds at untreated paddy fields, upland fields and orchard fields (including non-cultivated land) in 10 areas. The amount of occurred weeds in each area was compared fresh weight with dry weight. The average percentage for ratio of dry weight to fresh weight in paddy fields was concluded to be ...

Abstract :

The aim of this study was to estimate the quantitative indexes of stand weed infestation and yields of three cultivars of spring wheat sown in sowing densities 500 and 800 grains per 1 m2. The study was conducted in 2006-2009 in the gray-brown podsolic soil formed from loess. The experimental factors were three cultivars of spring wheat different in respect of morphology: Nawra, Zadra and Kory ...

Abstract :

Study of weed control using herbicides with tillage practice was conducted. Experimental design was split plot in RCB with three replications. Main plot was 3 pre-emergence herbicide applications, atrazine at the rate of 400 grams active ingredient per rai, pendimethalin + imazapic at the rate 133+12 grams active ingredient per rai and no application. Sub plot was 4 tillage methods, no tillage ...
