Trichoderma spp. is a cosmopolitan group of soil fungi which plays a remarkable role in stimulating plant growth after interacting with plant roots and has good application prospects in intensive agriculture. In this study, rice straw and amino acids improved the population of Trichoderma guizhouense NJAU4742 under solid-state fermentation and helped us develop a new type of organic fertilizer. The effects of this biological organic fertilizer were evaluated in the growth of peppers (Capsicum annuum L.) for two seasons under sandy and mountain soils. In the first season, the yields in T6 (0.06% solid fermentation products in soil) and AT6 (added 0.06% solid fermentation products and 1% amino acid organic fertilizer in soil) treatments were increased by 41.8% and 52.3% in sandy soil and by 51.6% and 46.5% in mountain soil, respectively, compared with chemical fertilizer. During the second season, the same trend was obtained in both sandy and mountain soils. Soil peroxidase activity (125.2 μmol·g−1 dw), urease activity (58.7 μmol·g−1 dw) and invertase activity (13.11 mg·g−1 dw) reached their highest levels in biological organic fertilizer compared to the treatments with chemical fertilizer and solid fermentation products. Redundancy analysis showed that crop yield was positively correlated with enzyme activities, soil organic carbon, total nitrogen, and available phosphorus. Thus, we demonstrated that NJAU4742-enriched biological organic fertilizer could accelerate the transformation of nutrients and promote pepper growth.

Capsicum Annuum L

  En México se siembran más de 100 variedades de chile (Capsicum annuum L.), es un cultivo altamente redituable y representa una actividad económica de importancia nacional. Actualmente, enfrenta graves problemas fitosanitarios por la presencia de enfermedades como la marchitez del chile, causada por un complejo de patógenos de suelo. Para el control de estas enfermedades, se utilizan fungicidas tóxicos y residuales, que contaminan el ambiente e inducen resistencia genética en los fitopatógenos. Por ello, es necesario buscar alternativas de control para solucionar este problema, por tanto, el objetivo de este trabajo fue evaluar el efecto antagónico de Trichoderma spp., contra los agentes causales de marchitez en confrontaciones in vitro mediante cultivos duales. El estudio se llevó acabo en 2016, en la Universidad Intercultural de Estado de Puebla, Huehuetla, Puebla, México. Se evaluaron tres aislamientos de Trichoderma provenientes de la rizósferas de árboles de aguacate, T. viride, T. harzianum y T. asperellum y tres aislamientos de los fitopatógenos P. capsici, F. oxysporum y R. solani obtenidos de las raíces de plantas de chile con síntomas de la marchitez. Los aislamientos se caracterizaron morfológicamente para su identificación. Los tres hongos antagonistas presentaron alto porcentaje de inhibición, T. asperellum mostró el 88.25%, T. viride 87.22% y T. harzianum con 87.8%. En las condiciones del estudio, T. asperellum, T. viride y T. harzianum, resultaron microorganismos antagónicos eficientes contra los fitopatógenos. Se sugiere realizar evaluaciones de biocontrol con estos aislamientos en invernadero y a campo abierto.

An investigation was carried out at experimental farm of Department of Seed Science and Technology, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) on bell pepper (Capsicum annuum L.) having nine different treatment combinations. The trial conducted in two consecutive years (2018 and 2019) with Randomized Complete Block Design. The experimental results revealed that all the treatment combination performed significantly superior than control. The treatment T2: Seed treatment with Trichoderma spp. @ 10 g/kg seed + vermicompost @ 50 q/ha + Neem cake application @ 12g/plant + foliar application of NPV @ 1 g/l once in 7 days (after borers appearance) recorded highest plant height (62.59 cm), higher number of branches per plant (5.77), highest number of fruits per plant (21.02), maximum fruit weight (49.85) and highest fruit yield (1047.73 g/plant, 9.43 kg/plot and 310.44 q/ha) as compared to the control. In overall investigation, the results concluded that the application of Trichoderma sp. along with vermicompost, neem cake and NPV gives better results in bell pepper cultivation to obtain higher crop growth and yield.
