Abstract

The objectives of this study were to evaluate the yield of different types of cucumbers from the perspective of yield components. The yield and yield components of nine cucumber cultivars (Beit Alpha, Greenhouse, and Japanese) grown hydroponically in a greenhouse were investigated. Fruit yield fresh weight in the Beit Alpha type was higher than that of the Japanese type, and the fruit yield fresh weight was significantly correlated with fruit yield dry weight, total dry matter (TDM), fraction of fruits, and number of fruits. However, the fruit yield fresh weight was not significantly correlated with intercepted light, light use efficiency (LUE), leaf area index, light extinction coefficient, and fruit dry matter content. High fruit yield dry weight was associated with a high TDM and the fraction of fruits. Moreover, the high TDM and fraction of fruits were associated with LUE and the number of fruits, respectively.

Highlights

Cucumbers (Cucumis sativus L.) are among the most widely cultivated vegetable crops worldwide and have many different genotypes [1]
According to data from the Ministry of Agriculture, Forestry and Fisheries, as much as 932 h of working time are required per 1000 m−2 in summer and autumn cultivation, which is 33% higher than the 709 h required for tomato cultivation [5]
Cucumber is generally a day neutral crop that induces both male female flowers on the same stem,isand the sex expression is affected by flowers onand the same stem, and the sex expression affected by environmental factors and environmental factors and genotypes. These results suggest that the study of varigenotypes [15,16]. These results suggest that the study of variety comparisons in cucumber ety comparisonsand in cucumber is insufficient, and are more varietytocomparisons arerelationship needed to is insufficient, more variety comparisons needed elucidate the elucidate the relationship between yield and yield components

Summary

Introduction

Cucumbers (Cucumis sativus L.) are among the most widely cultivated vegetable crops worldwide and have many different genotypes [1]. Despite the wide variation in cucumbers worldwide, Japanese cucumbers have relatively narrow diversity [2]. Japanese cucumbers have strict standards for fruit size. Young cucumbers are approximately 22 cm in length and 100 g in weight. Producing a variety of cucumbers may provide opportunities for market expansion and increased consumption. Japanese cucumber yield is far lower, at 3.4 kg m−2 and 10.7 kg m−2 in summer–autumn and winter–spring periods, respectively [3], than in the Netherlands, at 72.8 kg m−2 [4]. According to data from the Ministry of Agriculture, Forestry and Fisheries, as much as 932 h of working time are required per 1000 m−2 in summer and autumn cultivation, which is 33% higher than the 709 h required for tomato cultivation [5]
