Phalsa (Grewia subinaequalis D.C.) is a native plant with nutritionally rich fruits, yet it faces challenges like uneven ripening and small fruit size. This study assessed the efficacy of organic nutrient sources, including Farm Yard Manure (F.Y.M.), Poultry Manure, and Jeevamrit, in improving Phalsa growth and fruit quality. Results revealed that the combination of F.Y.M. and Poultry Manure with Jeevamrit significantly enhanced vegetative growth, increasing shoot length, number of shoots per plant, and inter-nodal length. These benefits are attributed to the nutrient-rich organic sources, which stimulate cell elongation and division, leading to accelerated plant growth. Furthermore, organic sources positively impacted fruit yield, with the highest yield observed under F.Y.M. and Poultry Manure with Jeevamrit treatment. Additionally, there were increased fruiting nodes and extended harvesting periods, contributing to enhanced fruit production. Phalsa fruit size and quality improved substantially due to organic source applications, resulting in larger fruit dimensions and elevated total soluble solids content. Jeevamrit and F.Y.M. facilitated better nutrient transport to developing fruits, enhancing metabolic processes and fruit size. Regarding sugar content, organic sources significantly influenced non-reducing and reducing sugars. F.Y.M. with Jeevamrit yielded higher non-reducing sugar content, while reducing sugar content increased with F.Y.M. and Jeeva Ghanamrit. Phalsa fruit acidity was not significantly affected by organic sources, but there was a non-significant increase in ascorbic acid content under various combination treatments. Economically, the benefit-cost ratio was most favourable with F.Y.M. and Poultry Manure combined with Jeevamrit, showcasing the economic viability of these organic nutrient sources in Phalsa cultivation. In conclusion, this study demonstrates the positive impact of organic nutrient sources, particularly F.Y.M., Poultry Manure, and Jeevamrit, on Phalsa plant growth, fruit yield, and fruit quality. These findings provide valuable insights into sustainable and organic methods for enhancing Phalsa cultivation, potentially leading to increased production and improved fruit quality in this indigenous crop. Further research should explore the applicability of these organic sources in different crops and regions.

“…In some areas, hazelnut groves 30 years of age with large plants are present. Periodically, hazelnut groves undergo pruning [59], which reduces canopy volume and can cause variation in reflectance due to the spectral mixing of soil and wood pixel signatures. The hazelnut is a deciduous plant, with an active vegetative growth phase during summer months, where irrigation intervention is often required, while pruning occurs during the vegetative rest period.…”

The production of “Nocciola Romana” hazelnuts in the province of Viterbo, Italy, has evolved into a highly efficient and profitable agro-industrial system. Our approach is based on a hierarchical framework utilizing aggregated data from multiple temporal data and sources, offering valuable insights into the spatial, temporal, and phenological distributions of hazelnut crops To achieve our goal, we harnessed the power of Google Earth Engine and utilized collections of satellite images from Sentinel-2 and Sentinel-1. By creating a dense stack of multi-temporal images, we precisely mapped hazelnut groves in the area. During the testing phase of our model pipeline, we achieved an F1-score of 99% by employing a Hierarchical Random Forest algorithm and conducting intensive sampling using high-resolution satellite imagery. Additionally, we employed a clustering process to further characterize the identified areas. Through this clustering process, we unveiled distinct regions exhibiting diverse spatial, spectral, and temporal responses. We successfully delineated the actual extent of hazelnut cultivation, totaling 22,780 hectares, in close accordance with national statistics, which reported 23,900 hectares in total and 21,700 hectares in production for the year 2022. In particular, we identified three distinct geographic distribution patterns of hazelnut orchards in the province of Viterbo, confined within the PDO (Protected Designation of Origin)-designated region. The methodology pursued, using three years of aggregate data and one for SAR with a spectral separation clustering hierarchical approach, has effectively allowed the identification of the specific perennial crop, enabling a deeper characterization of various aspects influenced by diverse environmental configurations and agronomic practices.The accurate mapping and characterization of hazelnut crops open opportunities for implementing precision agriculture strategies, thereby promoting sustainability and maximizing yields in this thriving agro-industrial system.

“…By expanding the circular economy concept to agricultural systems and environmental restoration, particular attention must be paid to the multipurpose plant species. In this context, hazel plant is an example of multipurpose plant, as it is a woody species cultivated to obtain direct food products (fruits), which have not undergone a process of absolute domestication and which are also found in the wild [25][26][27][28][29][30]. Therefore, they are species of plants which can be conveniently used for reforestation or for orchards purposes.…”

Corylus avellana L. is one of the most cultivated species in the world. Mainly utilized with the purpose of obtaining food material, hazel trees cannot guarantee constant kernels productions given the threats related to pathogens and to adverse conditions, especially in a globalisation and global changes scenarios. This matter led us to consider the opportunity of using hazel tree in all its parts and for several purposes, due to its multifunctional characteristics. As a pioneer species, it is a precious plant useful for forest restoration purposes and for forest successions/wildlife facilitation. Its roots enter into symbiosis with truffles making this species exploitable for hazelnuts and truffles production. The precious elements contained in what is considered "waste" deriving from hazel crops (i.e., leaves, skins, shells, husks and pruning material), could be reused and valorised in the perspective of a circular economy that is opposed to a linear one. In particular, a list of several phenolic compounds detected in hazelnut shells has been reported in literature to prevent and delay many human diseases due to their antioxidant properties and to free radical scavenging activities, with implications potentially useful even in the fight against COVID-19. All this makes hazel crop by-products interesting to be valorised as a chemical compound source for human health, even more than a biomass fuel or for bio-char applications. The multiple possible uses of the hazel tree would lead to alternative productions than the only nut productions, avoiding significant economic losses, would decrease the cost of disposal of crops residues and would increase the sustainability of agro-ecosystems by reducing, among other things, the production of wastes and of greenhouse gases deriving from the usual burning of residues which often happens directly in fields.
