Abstract

In order to study the effects of intra and inter-row spaces and planting pattern on the yield components, seed and oil yield of pumpkin (Cucurbita pepo L.), a field experiment was conducted as split-split plot based on randomized block design with three replications during 2009-2010 at the Agricultural Research Station of Ferdowsi University of Mashhad, Iran. Two levels of inter-row space (1 and 2 m), two levels of intra-row space (20 and 40 cm) and two planting patterns (one and two ways) were allocated to main, sub and sub-sub plots, respectively. The results indicated that the effect of inter-row space on number of seeds per ha-1 was significant (p<0.05). The number of fruits and seeds per ha-1, seed and oil yield and oil percent were significantly (p<0.05) affected by intra-row space. The effect of planting pattern was significant (p<0.05) on the number of fruits per ha-1, seed and oil yield and oil. The interaction effect between inter and intra-row spaces were significant on the number of fruits and seeds per ha-1 and oil percent of pumpkin. The interaction effects between intra-row space and planting pattern on the number of fruits per ha-1 and oil percent in squash was significant. With increasing intra-row space, the seed yield decreased (from 697kg h-l to 631kg h-l). The highest and the lowest amounts of seed yield were observed in two and one way with 715 and 613 kg.ha-l, respectively. The positive significant correlation between the fruits per ha-1 and seeds and oil yield and seed yield and oil yield were observed. It seems that the arrangement of row space increased the fruit number and seed and oil yields of pumpkin due to decreasing of its vegetative growth.
اثر فاصله روی ردیف و بین ردیف و آرایش کاشت بر اجزای عملکرد، عملکرد دانه و روغن کدو پوست کاغذی (Cucurbita pepo L.)
2009-2010年,在伊朗马什哈德Ferdowsi大学农业研究站,采用3个重复的随机区组设计,进行了南瓜(Cucurbita pepo L.)行内、行间间距和种植方式对南瓜产量构成、种子和油料产量的影响。主样地、副样地和副样地分别设置两层行间空间(1和2 m)、两层行内空间(20和40 cm)和两种种植模式(一种和两种方式)。结果表明,行距对每ha-1种子数的影响显著(p<0.05)。行内间距对每公顷果实和种子数、籽粒产量和出油率均有显著影响(p<0.05)。不同种植方式对每公顷果实数、籽粒产量和油分产量的影响均显著(p<0.05)。行间和行内互作对南瓜每公顷果实和种子数及出油率的影响显著。行内间距和种植方式对南瓜每公顷果实数和含油率的互作效应显著。随着行间距的增加,种子产量下降(从697kg h-l降至631kg h-l)。两种方式产量最高,一种方式产量最低,分别为715和613 kg。分别ha-l。每ha-1果数与种子产量、油分产量、种子产量和油分产量呈显著正相关。行距安排似乎通过抑制南瓜的营养生长而提高了南瓜的果实数和籽油产量。
