| Spanish abstract | Se evaluaron las características físico-químicas, microflora y calidad del guano proveniente del murciélago insectívoro Hipposideros speoris. Se evaluó el efecto del guano en el crecimiento de cultivos. Los resultados indicaron que los pellets fecales contenían cantidades elevadas de material organica, carbono, nitrógeno y fosfato. Los contenidos de calcio, magnesio, bacterias, actinomicetos y hongos fueron mayores en el guano que en los pellets fecales. Las características físico químicas y la carga microbial del guano y los pellets fecales fueron significativamente diferentes (P<0.05). en una prueba con macetas estas recibieron suelo, suelo mezclado con diferentes cantidades de guano (w/w), guano + heces de granja (HG) y sólo HG. Después de tres o seis semanas de cultivo se evaluaron varios parámetros. Los cultivos mostraron mayores crecimientos, contenidos de materia seca y nitrógeno y captura de nitrógeno en los suelos con guano 20:1 y estos fueron significativamente diferentes del control (P<0.05). Los resultaron mostraron que la incorporación de pequeñas cantidades de guano de murciélago mejora la producción de cultivos. La importancia de conservar murciélagos insectívoros en campos agrícolas y su guano es enfatizada |
| English abstract | This study aimed at assessing the physicochemical characteristics, microflora and manure quality of guano of an endemic insectivorous cave bat Hipposideros speoris. The impact of bat guano on crop growth was also assessed. Results indicated that organic matter, total carbon, total nitrogen and phosphate were high in faecal pellets. Calcium, magnesium, bacteria, actinomycetes and fungi were higher in humus-like guano than faecal pellets. Physicochemical features and microbial load between faecal pellets and humus-like guano significantly differed (p<0.05). One set control pots received red loamy soil; four sets of experimental pots received soil amended with different quantity of guano (w/w); one set each with guano + farm yard manure (FYM) and FYM. After three weeks (finger millet) and six weeks (black gram) of growth, crops were harvested and assessed various parameters. Both crops, in soil amended with guano at the ratio of 20:1 showed the highest shoot length, total dry matter, nitrogen content and nitrogen uptake. The shoot length, total dry matter, nitrogen content and nitrogen uptake in both crops were significantly differed between treatment 20:1 and control (p<0.05). The results clearly indicated that incorporation of low amount of bat guano into the soil enhances crop production. Importance of conservation of insectivorous bats in agricultural fields and their guano have been emphasized |
