Rubikun, Wahyu Setiawan (2019) Pengaruh Pemberian Perbedaan Jenis Pupuk Hayati, Dosis Serta Interval Aplikasi Terhadap Sifat Kimia Tanah Dan Produksi Tanaman Cabai (Capsicum Annuum L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Upaya untuk meningkatkan produksi tanaman cabai serta ketersediaan hara yang tidak berdampak buruk pada kesehatan tanah adalah dengan pengaplikasian pupuk hayati. Pupuk hayati mengandung mikroorganisme yang mampu membantu menyediakan unsur hara bagi tanaman. Penelitian ini ditujukan untuk mempelajari pengaruh pemberian berbagai dosis pupuk hayati serta interval aplikasi terhadap kesuburan tanah dan produksi tanaman cabai besar. Penelitian dilaksanakan di Kebun Percobaan Agrotechnopark, Universitas Brawijaya, Desa Jatikerto, Kecamatan Kromengan, Kabupaten Malang yang berlangsung pada Bulan Maret hingga September 2018. Penelitian ini menggunakan Rancangan Acak Kelompok Faktorial (RAKF), dengan 12 kombinasi perlakuan dan 3 ulangan. Perlakuan terdiri dari pupuk hayati B yaitu B2 dan B3; dosis D1: 50 g/l, D2: 100 g/l, D3: 200g/l;dan interval aplikasi I1: 14 hari sekali dan I2: 21 hari sekali. Parameter yang diukur meliputi: kadar NPK, Corganik, pH tanah pada awal sebelum penelitian, tinggi tanaman, produksi, residu NPK di tanah pada akhir penelitian , dan kadar NPK tanaman cabai. Analisa data dilakukan dengan menggunakan software Microsoft Excel dan dianalisis sidikragamnya dengan menggunakan software Genstat 6.0 discovery edition. Pemberian pupuk hayati dengan berbagai dosis dan interval aplikasi tidak berpengaruh nyata terhadap pertumbuhan tanaman cabai, tetapi berpengaruh nyata terhadap produksi tanaman cabai, dimana pada perlakuan pupuk hayati B3, dosis 100 g/l dan interval aplikasi 14 hari mampu meningkatkan produksi sebesar 525,5 g/petak jika dibandingkan dengan perlakuan pupuk hayati B3, dosis 50 g/l dan interval aplikasi 14 hari. Aplikasi pupuk hayati berperan sebagai penyedia hara dalam tanah dan pengendali patogen tanaman, adapun bila diaplikasikan dengan dosis serta interval yang tepat akan menghasilkan pertumbuhan yang baik serta dapat meningkatkan kualitas dan kuantitas produksi. Pemberian pupuk hayati dengan berbagai dosis dan interval aplikasi tidak berpengaruh nyata terhadap residu unsur hara (NPK) di tanah dan kadar NPK tanaman, kecuali C-organik. Dimana pada perlakuan pupuk hayati B2, dosis 200 g/l dan interval aplikasi 14 hari mampu meningkatkan kandungan C-organik tanah sebesar 0,48% jika dibandingkan dengan perlakuan pupuk hayati B3, dosis 200 g/l dan interval aplikasi 14 hari. Hal ini dapat disebabkan oleh bakteri Achromobacter sp yang terdapat pada pupuk hayati B2. Untuk meningkatkan produksi tanaman cabai sebaiknya menggunakan pupuk pupuk hayati B3 dengan dosis pupuk hayati 200 g/l dan interval aplikasi 14 hari.
English Abstract
One of the efforts to increase the plant production and nutrient availability that does not adversely affect soil health is by applying biofertilizers. Biofertilizers contain microorganisms that can help the plant in providing its nutrients. This study aimed to determine the effect of various doses of biofertilizers and application intervals on soil fertility and the production of large chili plants. This research took place in Agrotechnopark, Brawijaya University, Jatikerto Village, Kromengan District, Malang Regency from March to September 2018. The method used for this research was Factorial Randomized Block Design with twelve treatment combinations and three replications. The treatment consisted of biofertilizer B, namely B2 and B3; dose D1: 50 g / l, D2: 100 g / l, D3: 200g / l; and interval application I1: 14 days and I2: once every 21 days. Parameters which were measured including initial soil nutrient content (e.g NPK, Organic-C), initial soil pH, plant growth, production, NPK residues, and NPK levels of plants. Data analysis was performed using Microsoft Excel software while the analysis of variance was done by using Genstat 6.0 discovery edition software. Application of biological fertilizers with various doses and application intervals did not significantly affect the growth of chili plants. Application of biofertilizers with various doses and application intervals had a significant effect on the production of chilli plants, which in the treatment of biofertilizer B3, dose 100g/l, interval application 14 days was able to increase the production by 525.5 gr /plot compared to biofertilizer B3, dose 100 g/l, interval application 21 days treatment. The application of biofertilizer acted as a provider of nutrients in the soil and controled the plant pathogens, could if the biofertilizer was applied at the right dosage and interval, it would produce good growth and could improve the production of quality and quantity. Provision of biological fertilizers with various doses and application intervals did not significantly affect all residues and NPK uptake of plants except soil organic-C. Biofertilizer B2 application, dose 200 g/l and interval application 14 days treatment, was able to increase soil organic-C by 0.48% as compared to biofertilizer B3, dose 200 g/l, interval application 50 g/l treatment. This condition could be caused by the bacteria Achromobacter sp which was found in B2 fertilizer. To increase the production of chili plants, it was better to use B3 biofertilizer of 200 g / l dosages with 14 days of application intervals.
