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

Drought is the global challenge of crop agriculture across the globe. The detrimental effect of drought hinders a significant growth and development impairment leading to devastating harvest losses. Maize, a vital staple for food faces future challenges with a rapidly expanding drought area. To address this challenge, scientists and breeders are urged to develop new varieties that are not only resistant or tolerant but also even potentially thrive under drought planting conditions. New breeding technologies involving molecular biology and biotechnology have been developed and implemented thus offering a promising solution. Genetic engineering has allowed humans to straightforwardly transfer beneficial genes across species and varieties, thus deliberating gene pool transfer of similar species and varieties. Furthermore, this technology has evolved to the level of creation, deletion, or modification of existing alleles with high precision through CRISPR/Cas9-mediated genome editing. This review article delves into the morpho-physiology, biochemical, and molecular responses of maize varieties against drought stress. It subsequently explores how genetic engineering has been utilized to optimize the selected genes underlying those responses. By exploring the current progress of genetic engineering, this article aims to prepare the ground for future advancement in combating drought through drought-tolerant maize varieties. Thus, this review article has the potential to contribute to improving food security in the increasing drought challenges.
