Effects of Organic Manures and Green Manuring on Growth, Yield, Economics and Quality of Lemongrass (Cymbopogon Flexuosus L.) In Custard Apple (Annona Squamosa L.) Based Agri-Horti System

Abstract

A field experiment was conducted to explore the effects of organic manures and green manuring practices on growth, yield attributes, quality and economics of lemongrass (Cymbopogon flexuosus L.) under custard apple (Annona squamosa L.) based agri-horti system. The findings indicated that growth, yield attributes and yield as well as oil composition, soil nutrient status, microbial populations were significantly increased due to the use of both organic manures and green manuring. The significantly higher results were obtained with vermicompost (2.5 t/ha) + Azotobacter, which was found superior over other practices in terms of growth, yield attributes, oil composition and its quality and soil nutrient status as well as economics of crop cultivation.

Green manure (Crotalaria juncea L.) enhances Origanum vulgare L. biomass accumulation, essential oil yield, and phytochemical properties

“…This confirms the importance of management technique in medicinal plants. Therefore, research shows the positive effects of using GM, as well as the combination of other organic fertilizers or low doses of mineral fertilizers (Rothé et al 2019, Watthier et al 2020, Peralta-Antonio et al 2021, Massey et al 2021, Honorato et al 2022.…”

“…and Echinacea purpurea (L.) Moench, and no increases in dry matter and chemical compounds were observed (Morais & Barbosa 2012, Susanti et al 2017. However, other studies have shown that this type of management can provide higher dry matter yields, essential oil production, bioactive constituents, and enzymatic activity (Adeniji & Kumoye 2020, He et al 2018, Massey et al 2021, Honorato et al 2022, showing that the production of medicinal plants is influenced by the management of GM as well as by the quality of the organic waste used.…”
