Workability of Summer-Autumn-Harvest Cherry Tomato in Open Field Culture Using Non-Training Cultivation with Net

The present study focused on an open-field cultivation method for cherry tomatoes, based on summer to autumn harvest that uses nets to induce the plants and involves no lateral shoot pruning (referred to as the sauvage cultivation method). The yields and qualities of cherry tomato cultivated in fields in Kanagawa, Japan, located in a warm climate zone, and Iwate/Hiroshima, where summer to autumn harvest cherry tomatoes are widely cultivated, were assessed for 2 or 3 years. The economic efficiencies of the sauvage cultivation method were also assessed based on agricultural management indices. The yields per unit area and per plant with the sauvage cultivation method of cherry tomatoes were equal to or higher than the yields using the conventional method, in which all lateral shoots are removed. Regarding the fruit quality, the sugar content of cherry tomatoes cultivated using the sauvage cultivation method in the field in Iwate was similar or lower compared with the conventional method. Regarding the economic efficiency of the sauvage cultivation method, the profit per 10 a of cherry tomatoes grown using the sauvage cultivation method was 860,000-1,100,000 yen. The duration of working hours was 333-568 hours; therefore, the profit per hour was 1,933-2,661 yen.

Effect of Presence or Absence of Calyx of Cherry Tomato on Storage Quality

2019

A large number of studies have been conducted on freshness retention in many different vegetables. If vegetables have a peduncle or calyx, they serve as a channel for transpiration. The results of studies involving lemons, eggplants, and husk tomato fruit suggest their influence on freshness retention of fruit. However, no study on cherry tomatoes has been conducted to examine the effects of a calyx on the storage quality of fruit. The present study, involving four varieties of cherry tomatoes that bear different shapes of fruit, aimed to examine the influence of a calyx on the fruit storage quality. When harvested cherry tomatoes were stored at 25°C, the weight loss and respiration rate of four varieties without a calyx were equal to or lower than those of cherry tomatoes with a calyx; the moisture and ascorbic acid contents of the four varieties without a calyx were equal to or higher than those of cherry tomatoes with a calyx. Whereas no mold grew on the four varieties without a calyx, it was identified on cherry tomatoes with a calyx. The mold incidence rates of round/oblate-shaped 'Chika' and 'Mini Carol' were significantly lower than the rates of pear-shaped 'Aiko' and 'Rosso Neapolitan', which suggests that the calyx shape influences the incidence of mold. The results of the study suggest that when cherry tomatoes are stored at 25°C, the storage quality of tomatoes without a calyx is better than that of cherry tomatoes with a calyx.
