“…Sahoo et al (2007) suggested that aqueous leaf extracts of two tree species showed a reduction of the fresh and dry weight of maize. Similar results were also reported by Oraon and Mondal (2020) that aqueous leaf extracts of Putranjiva roxburghii showed that dry weight of chickpea seeds significantly decreased upon increasing concentrations.…”

Background: Agroforestry might be a better strategy for sustainable land use and crop production. Allelopathic effect of Streblus asper Lour. (Moraceae) an agroforestry tree species was documented on chickpea (Cicer arietinum L.) seed germination and seedling growth. Methods: The present study was conducted to evaluate the allelopathic potentialities of different concentrations (0.125%, 0.25%, 0.5%, 1.0%, 2.5% and 5%) of aqueous leaf extracts of S. asper on seed germination and seedling growth in laboratory based experiments. The allelopathic potentialities were studied based on seed germination, germination rate, root length, shoot length, biomass, seed vigor index etc. Result: The inhibitory effect was more pronounced with the increasing concentrations of aqueous extracts. 5% aqueous leaf extracts showed a maximum inhibitory effect on seed germination, root length, shoot length, dry weight of root and shoot as compared to control. Based on the allelopathic index, concentrations of 5% aqueous extract showed a strong inhibitory effect. Aqueous leaf extracts contain water-soluble allelochemicals which affect the seed germination and seedling growth. The inhibitory allelopathic effect can be taken as serious consideration before plantation of chickpea in an association of this tree species because of its inhibitory effect on seed germination and early stages of development.

“…e present findings are in accordance with Das et al (2012), who found that the aqueous leachates of leaf litter of seven tree species significantly (p < 0.01) reduced the SVI of gram (chickpea) seeds. Alqarawi et al (2018) reported a strong inhibitory effect of aqueous leaf extracts of Rhazya stricta on SVI of Salsola villosa, while Oraon and Mondal (2020) reported that the SVI of chickpea decreased significantly (p < 0.001) with increased concentrations of aqueous leaf extracts of Putranjiva roxburghii.…”

The present study reveals the allelopathic effect of aqueous leaf and root extracts of Hyptis suaveolens (L.) Poit. and Leucas cephalotes (Roth) Spreng. on seed germination and early growth of Oryza sativa ‘Gobindobhog.’ Leaf and root extracts at different concentrations (0.5%, 1%, 2.5%, 4%, and 5%) were used to study the effect in laboratory-based experiments. After 5 days of incubation, seed germination and root and shoot length of rice seedlings were measured, and both H. suaveolens and L. cephalotes showed allelopathic effects on seed germination and growth parameters. Hyptis suaveolens showed a more pronounced effect at 5% concentration of aqueous leaf and root extracts than L. cephalotes . The inhibitory effects were as follows: root length > seed germination > shoot length. Both H. suaveolens and L. cephalotes impede seed germination and early growth of rice by releasing water-soluble allelochemicals from their leaves and roots.

“…P. caninum leaf extract can suppress the pathogenic curvularia, although the pathogenic curvularia also has phytotoxic substances against other organisms such as inhibition of bacteria such as Escherichia coli and also has antioxidant activity and inhibition of acetylcholinesterase (Kaaniche et al, 2019). This is also supported by research by Oraon and Mondal (2020) that the initial growth of Cicer Arietinum L. was hampered after being given a Putranjiva roxburghii Wall leaf extract license. at high concentrations (100%), because the extract contains allelopathic substances.…”

Rice is a plant that has been intensively breed, especially in Asia, most of the population’s staple food is rice. There were Many types of rice varieties have been developed for high yeald production. Different rice diseases arise that many treat to reduce production. Such as curvularia spotting disease caused by the fungus Curvularia sp. Infection of Curvularia species causing leaf spots, leaf blights, kernel root, grain deformation and other diseases are well known globally. It was discovered that the small brown oval spots on the Ciherang rice variety cultivated in Bali, Indonesia was caused by Curvularia verruculosa. This disease could reduce the rice yield up to almost 50%. The application of commercial fungicide by the local farmers has not been satisfactorily successful in term of controlling the disease but instead bring damages to the environment and the soil as well. Farmer’s safety is also another serious issue. The current studi develop a natural and green fungicide to check the efficacy of Piper caninum extract against the fungi. Research in the laboratory uses a completely randomized design and research in the field uses a randomized group design.The method of making leaf extracts uses maceration method. Diffusion well technique showed a strong inhibition of the abstract against the C. verruculosa with 22mm inhibition. Zone with a total inhibition of 4% extract concentration. The minimum inhibitory concentration (MIC) was low of 0.5%. Scanning electron images of the treated fungi showed hollow and wrinkled mycelia morphology indicating lysis of the cell has occurred. P. caninum leaf extract at a concentration of 3% provides the highest obstacle to the intensity of C. verruculosa disease, whereas in the treatment of leaf extract concentration p. caninum 4% intensity of C. verrucuosa disease has decreased because rice plants are toxic at a concentration of 4%. Further research is needed regarding the treatment of P. caninum leaf extract against C. verruculosa in rice fields.
