“…Individual fruit weight has significant and positive correlation with fruit/plant (0.93*), fruit length (0.92*), and fruit diameter (0.88*). The findings are in agreement with the findings of (Uddain et al, 2019). The yield of squash was positively correlated with fruit length, fruit diameter, fruit/plant and Individual fruit weight.…”

The experiment was conducted at the research field of Agricultural Research Station, Rajbari, Dinajpur during rabi season of 2018-19 and 2019-20 to develop a profitable and economic fertilizer dose and optimum planting time for Squash and to increase the productivity and yield. Two different dates of planting viz. 15 November and 30 November considered as factor A and different organic manures viz., vermicompost, poultry manure and cowdung considered as factor B. The experiment was laid out in randomized complete block (RCB) design (Factorial) with three replications. Organic manures and planting time showed significant effects on most of the parameters. In case of organic manures, highest individual fruit weight (1707.50 g) and fruit yield (32.43 tha-1) was recorded from vermicompost whereas the lowest fruit weight (1233.17 g) and fruit yield (23.52 tha-1) was recorded from cowdung application. In case of planting time, the highest individual fruit weight (1747.11 g) and fruit yield (29.61 tha-1) was recorded from 15 November planting date whereas the lowest fruit weight (1196.44 g) and fruit yield (25.86 tha-1) was recorded from 30 November planting date. For combination, highest individual fruit weight (2153.66g) and fruit yield (34.06 tha-1) were recorded from vermicompost with 15 November planting date while the lowest individual fruit weight (1105.33g) and fruit yield (20.56 tha-1) were recorded from cowdung with 30 November planting date. Vermicompost with 15 November planting date was found suitable for total productivity and economic return of the system.

“…No significant interactions between the effect of the cultivar and horticultural system on the sugars content in the tested fruits were observed. Compared to the presented results, higher average sugars content was reported by other authors in the fruits of Cucurbita maxima [42], Cucurbita pepo [44,45], and Cucurbita moschata D. [46]. Other studies reported that courgette fruits also contain galactose, raffinose, stachyose, and starch.…”

Organic agriculture is considered one of the elements of sustainable food production and consumption, mainly due to its limited impact on the natural environment. At the same time, the quality features of organically produced foods, especially sensory attributes and health promoting values, are important factors determining consumers’ interest, and therefore play a key role in the organic sector’s development. The aim of this study was to investigate the sensory characteristics and concentrations of sugars and selected health-promoting bioactive compounds of organic courgette compared to conventionally grown courgette. In addition, untargeted metabolomic analysis of the courgette fruits was performed. The results of this study did not show a significant effect of the horticultural system (organic vs. conventional) on the concentrations of vitamin C, carotenoids, and chlorophylls in the courgette fruits. However, the fruits from the organic systems were significantly richer in sugars when compared to the conventionally cultivated ones (p = 0.038). Moreover, the organic fruits fertilized with manure contained significantly higher amounts of polyphenols, including gallic acid (p = 0.016), chlorogenic acid (p = 0.012), ferulic acid (p = 0.019), and quercetin-3-O-rutinoside (p = 0.020) compared to the conventional fruits. The untargeted analysis detected features significantly differentiating courgette fruits depending on the cultivar and horticultural system. Some significant differences in sensory values were also identified between fruits representing the two cultivars and coming from the horticultural systems compared in the study. Conventional courgettes were characterized by the most intensive peel color and aquosity, but at the same time were the least hard and firm compared to the fruits from the two organic systems. There was also a trend towards higher overall quality of the organically grown fruits. The presented study shows that the organic and conventional courgette fruits differ in a number of quality features which can influence consumers’ health and purchasing choices.
