The reform of the European Union's sugar regime caused potential decreasing beet prices. Therefore, the Speeding Up Sugar Yield (SUSY) project was initiated. At the start, a 3 × 15 target was formulated: in 2015 the national average sugar yield in the Netherlands equals 15 t/ha (60% of the sugar beet potential) and the total variable costs 15 euro/t sugar beet, aspiring a saving on total variab...

A field experiment was conducted in two consecutive years to find out the efficacy of poultry refuse (PR), mustard oilcake (MOC), and Furadan 5G for the management of root-knot disease (Meloidogyne incognita) of tomato. Soil was treated with PR @ 3 and 5 t/ha, MOC @ 0.3 and 0.6 t/ha 3 weeks before transplanting and Furadan 5G @ 40 kg/ha on the day of transplanting of tomato seedlings. PR @ 3 t/...

The aim of this experiment was to evaluate the biomass yield and chemical composition of the essential oil of clove basil in response to doses of broiler litter (0, 5, 10, 15 and 20 t ha-1) added in presence of triple superphosphate (200 kg ha-1) or without it. Before the first harvest, the height of the plants increased significantly (34.42 cm) when 15 tonnes ha-1 broiler litter were added to ...

Two species of Trichogramma wasps were assessed for their effectiveness against yellow stem borer Scirpophaga incertulas. A laboratory cage test with T. japonicum and T. chilonis showed that both species parasitized yellow stem borer egg masses at 60.0% ± 9.13% and 40.7% ± 7.11%, respectively, with egg parasitism rates of 15.8% ± 22.2% for T. japonicum and 2.8% ± 5.0% for T. chilonis. Once the ...

Weeds are a major constraint to the success of dry-seeded rice (DSR). The main means of managing these in a DSR system is through chemical weed control using herbicides. However, the use of herbicides alone may not be sustainable in the long term. Approaches that aim for high crop competitiveness therefore need to be exploited. One such approach is the use of high rice seeding rates. Experiment...
