Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk hayati Azotobacter terhadap pertumbuhan jagung manis varietas SD3 IPB. Penelitian dilaksanakan di Kebun Cikabayan Kampus IPB Dramaga- Bogor pada bulan Juni-Agustus 2018. Perlakuan yang diuji terdiri dari enam perlakuan yaitu: P0: 50% NPK, P1: 100% NPK, P2: 50% NPK + 1 ml /pot pupuk hayati cair, P3: 50% NPK + 1 ml/pot Pupuk Hayati cair steril, P4: 50% NPK +5 gram /pot Pupuk Hayati Padat, P5: 50% NPK + 5 gram/pot Pupuk Hayati Padat Steril. Enam perlakuan tersebut disusun dalam Rancangan Acak Lengkap (RAL) dengan lima ulangan. Parameter pertumbuhan tanaman yang diamati meliputi jumlah daun, tinggi tanaman, berat brangkasan basah dan brangkasan kering dan bobot akar jagung. Data yang diperoleh dianalisis menggunakan ragam ANOVA dan DMRT taraf 5%. Hasil penelitian menunjukkan perlakuan P4 (50% NPK +5 gram /pot pupuk hayati padat) memiliki rata-rata tinggi tanaman yang lebih baik jika dibandingkan dengan perlakuan lain, terdapat peningkatan tinggi tanaman sebesar 4,4% jika dibandingkan dengan perlakuan P1 (100% NPK). Perlakuan P2 (50% NPK +I ml/pot pupuk hayati cair) memiliki nilai terbaik pada pembentukan jumlah helai daun dan pembentukan biomassa akar baik basah dan kering dengan nilai berurutan 15,23 gram dan 2,25 gram. Penggunaan kombinasi pupuk hayati yang diperkaya Azotobacter 33 dan NPK memberikan pengaruh yang signifikan terhadap pertumbuhan tanaman jagung pada fase vegetatif

Abstract

Melon are plants that are sensitive to environmental changes. Currently, developing technology for cultivating melons in greenhouses is used to modify the microclimate for the growth of melon plants. This research aims to determine the effect of microclimate and different types of planting media on growth response of sweet net variety melon plants that planted in the Politeknik Negeri Jember smart green house. The research was carried out in January – May 2024. The treatments tested consisted of two treatments, namely: the use of soil media+compos and cocopeat media which would be repeated 15 times. The parameters observed include microclimate (temperature and humidity) and also plant growth indicators including plant length and number of leaves, number of flowers, and potential weight of melon. The data obtained were analyzed using the T-test. The research results show that the microclimate inside the Politeknik Negeri Jember smart green house is still classified as an optimal microclimate to support the growth of melon plants. Apart from that, the use of cocopeat planting media was able to provide the best results for the length of the melon plants in the 4th to 6th week of observation, but there was no significant difference in the parameters of the number of leaves, number of flowers and potential weight of melon of. The use of cocopeat media and soil media are both good media in supporting the growth of melon plants in a greenhouse.
