    Hybrid Deep Learning Method for Diagnosis of Cucurbita Leaf Diseases

    V. Nirmala1,*, B. Gomathy2

    Computer Systems Science and Engineering, Vol.44, No.3, pp. 2585-2601, 2023, DOI:10.32604/csse.2023.027512

    Abstract In agricultural engineering, the main challenge is on methodologies used for disease detection. The manual methods depend on the experience of the personal. Due to large variation in environmental condition, disease diagnosis and classification becomes a challenging task. Apart from the disease, the leaves are affected by climate changes which is hard for the image processing method to discriminate the disease from the other background. In Cucurbita gourd family, the disease severity examination of leaf samples through computer vision, and deep learning methodologies have gained popularity in recent years. In this paper, a hybrid method based on Convolutional Neural Network… More >

    Abstract Salt stress is one of the major abiotic stress in plants. However, traditional approaches are not always efficient in conferring salt tolerance. Experiments were conducted to understand the role of Trichoderma spp. (T. harzianum and T. viride) in growth, chlorophyll (Chl) synthesis, and proline accumulation of C. pepo exposed to salinity stress. There were three salt stress (50, 100, and 150 mM NaCl) lavels and three different Trichoderma inoculation viz. T. harzianum, T. viride, and T. harzianum + T. viride. Salt stress significantly declined the growth in terms of the shoot and root lengths; however, it was improved by the… More >

    Dynamic growth of squash (Cucurbita pepo L.) on a substrate based on vermicompost in the greenhouse

    Orozco V JA1, E Galindo P2, MA Segura C1, M Fortis H1, P Preciado R1, P Yescas C1, JA Montemayor T1

    Phyton-International Journal of Experimental Botany, Vol.85, pp. 117-124, 2016, DOI:10.32604/phyton.2016.85.117

    Abstract The aim of this study was to establish the dynamics of growth and allocation of photosynthates in squash (Cucurbita pepo L.) cultivated in a semiarid region under greenhouse conditions and in an organic substrate. Squash seeds were sown in two substrates (one mineral and other organic). The first consisted of a mixture of sand and pumice on a volume basis, while the organic consisted of sand and pumice mixed with vermicompost, both in plastic pots. The substrates were for two treatments [Inorganic (IT) and Organic Treatment (OT)] with sixteen repetitions on a completely randomized design. After emergence, plants were fertilized… More >

    Productive efficiencies in corn, bean and squash (Cucurbita pepo L.) associations, intercropped with rows of fruit trees

    Molina-Anzures MF1, JL Chávez-Servia2, A Gil-Muñoz1, PA López1, E Hernández-Romero1, E Ortiz-Torres1

    Phyton-International Journal of Experimental Botany, Vol.85, pp. 36-50, 2016, DOI:10.32604/phyton.2016.85.036

    Abstract Mesoamerican agrosystem ‘milpa’ is the association of maize, beans (Phaseolus sp.) and squash (Cucurbits sp.) in the same space and time. It is characterized by the production of a large diversity of species in small areas, but currently its use tends to decrease because of technological introductions of monocultures. In this work, the yield and productive efficiency of the association maize, beans and squash, intercropped with fruit tree rows were evaluated in two locations from Puebla, Mexico, through 32 experimental treatments clustered in three agrosystems. They were: triple associations of maize-beans-squash intercropped with fruit trees, double associations maize-beans without fruit… More >
