Management of Branched Broomrape in Field Processing Tomato Crop
In recent years, there has been a considerable increase in land area used for tomato (Lycopersicon esculentum Mill.) in many countries around the world. The essential role is played by Italy at a worldwide level as the country with the third biggest production of tomatoes for processing. Phelipanche ramosa (L) Pomel, commonly known as branched broomrape, is a root holoparasitic weed for many crops, particularly for the processing tomato. Due to its physical and metabolic overlap with the crop, its underground parasitism, and hardly destructible seed bank, the control of this parasite in the field is difficult. Results of research studies, many of them on environmental-friendly methods such as preventive, agronomic, and biological carried out in southern Italy, are discussed and summarized. The results can constitute a relevant basis for further experimental studies
Qualitative characterisation of cultivated and wild edible plants: Mineral elements, phenols content and antioxidant capacity
This study investigated the qualitative characteristics of several edible wild herbaceous species, including those most consumed in Foggia Province (southern Italy). Analysis of qualitative characteristics was performed for the edible parts of 11 wild species (Beta vulgaris L., Foeniculum vulgare Miller, Centaurea solstitialis L., Cichorium intybus L., Scolymus hispanicus L., Sonchus oleraceus L., Borago officinalis L., Diplotaxis erucoides L., Diplotaxis tenuifolia (L.) DC, Sinapis arvensis L., Portulaca oleracea L.) and three cultivated species (C. intybus, B. officinalis, D. tenuifolia). The plants were collected from areas in the Foggia countryside, and the edible part of each species was analysed for dry matter, protein, cation and anion contents as well as total phenols and antioxidant activities. Among the cations, calcium was the most differentiated among species, ranging 784 mg kg-1 fresh weight (Fw) for B. vulgaris to 5886 mg kg-1 Fw for S. hispanicus. The nitrate contents were also highly variable, from 75 mg kg-1 Fw for C. intybus to 3874 mg kg-1 Fw for D. tenuifolia. Total polyphenols ranged from 1054 mg GAE mg kg-1 Fw for C. solstitialis to 3664 mg GAE mg kg-1 Fw for S. arvensis. Antioxidant activities ranged from 839 mg TE kg-1 Fw for B. vulgaris to 5658 mg TE kg-1 Fw for C. intybus. Significant differences were also noted between wild and cultivated plants in the qualitative parameters. Total polyphenols and antioxidant activity were higher in wild C. intybus and B. officinalis than in their cultivated counterparts. Multivariate analysis (cluster analysis and linear discriminant analysis) allowed integration of the ANOVA data to determine the qualitative characteristics of the wild species that contribute most to group differences. The results of the present study aims at improve the current knowledges about edible wild species as vegetable sources in the Mediterranean diet

Vegetative and Reproductive Responses Induced by Organo-Mineral Fertilizers on Young Trees of Almond cv. Tuono Grown in a Medium-High Density Plantation
Field experiments were conducted in three successive seasons (2019–2021) to evaluate the effects of four commercial organo-mineral fertilizers with biostimulating action (Hendophyt®, Ergostim®, and Radicon®) on the vegetative and productive performance of young almond trees (Prunus dulcis, cv. Tuono) grown in a semiarid climate in Southern Italy. Foliar treatments were applied three times during each season (at the swollen bud, beginning of flowering, and fruit set-beginning of fruit growth stages). Both 2020 and 2021 were adversely affected by late frosts, resulting in damage to the flowers and small fruits without any positive effect of the biostimulant applications. In contrast, the results obtained during the normal climate year (2019) indicated that the growth of trunk diameter and shoot length of trees tended to increase in biostimulant treatments compared to those of the control. The number of buds and flowers per unit length of the branch revealed no significant differences among years and all compared treatments. However, in 2019, the fruit set percentage, number, and weight of kernels per tree were significantly higher in the biostimulant treatments compared to those of the control. To this regard, the use of biofertilizers is suitable for maintaining soil fertility and improving crop productivity This information holds significance for almond tree growers
