Abstract

Effect of spacing size and shape on oil pumpkin yield (Cucurbita pepo L. var. oleifera) was investigated in two – year field experiments during 2004 and 2005 on The College of Agriculture at Križevci experimental fields. The investigated planting distances were: 100x100, 140x70, 140 x 50, 80 x 80 and 140x30 cm. The experiment was set out by to the Latin square method with five replications, and data was analyzed using analysis of variance. Austrian cultivar Gleissdorf was tested. Number of fruits per plant, average fruit weight, number of fruits per hectare, yield of fruits per hectare, average seed weight per fruit and seed yield per hectare were established.
Highly significant large number of fruits per plant in both years was established at greater spacing size (100x100 cm – 1.43 fruit/plant in 2004; 140x70 cm – 1.1 fruit/plant in 2005). Average fruit weight regularly was higher at greater spacing size (140x70 cm – 4239 g in 2004; and 100x100 cm – 4183 g in 2005) but not significant.
Even though the differences were not significant between treatmants in both years the greatest number of fruits per hectare (16 167- 2004; 13 917 – 2005) and fruit yield per hectare (60.1 t/ha – 2004; 54.2 t/ha – 2005) ) was obtained at spacing 140x30 cm.
The highest seed yield per hectare in both years (1397.2 kg/ha – 2004; 1167.6 kg/ha – 2005) was obtained at the same spacing (140x30 cm) but high significant only in 2004 year.
