Application of Biofertilizer and NPK Fertilizer on Growth and Production of Maize (Zea mays L.)

Farmers' habits in cultivating maize include excessive use of chemical fertilizers and pesticides which cause environmental pollution and decreased soil quality, both chemical, physical, and biological, affecting low production, therefore efforts are needed to remain productive, namely by using biological fertilizers for soil improvement and reduction. giving a dose of NPK fertilizer so that the soil is not contaminated. The research objective was to determine the response of growth and production of maize to the application of biological fertilizers and NPK fertilizers. The research was conducted in Telaga Sari Village, Sunggal Subdistrict, Deli Serdang Regency from April 2020 to July 2020. The research used a factorial randomized block design, namely the first factor was giving biological fertilizer consisting of 0, 400, 800 and the second factor was giving NPK fertilizer consisting of 0, 100, 200, 300. The parameters observed were plant height, leaf area, stem diameter, dry seed weight per plant sample, dry seed weight per plot, number of ears, ear length. The results showed that the application of biological fertilizers and NPK did not significantly affect all parameters, but the application of biological fertilizers and NPK fertilizers on the growth and production of maize resulted in a significant effect on dry seed weight per plot

The experimental method used was factorial Randomized Block Design (RBD) with 2 factors and 3 replications, the first-factor being coconut varieties palm ( D x P Yangambie, D x P Simalungun) and the second factor is the dose of Azotobacter chroococcum / plant (0, 20, 40, 60 ml/seed). The results showed that the application of Azotobacter chroococum significantly increased the height, weight of fresh shoot, and weight of dry shoot and un significant increase in the number of leaves, total leaf area, the weight of fresh root, and weight of dry root. The use of two oil palm varieties and interactions un significantly to all observation variables

Growth And Production Of Several Rice Varieties With The Biochar From Different Sources Of Materials

This research will be carried out in the experimental land of the Tanjung Morawa Seed Center, Lubuk Pakam District, Deli Serdang Regency. The purpose of this research is to find out how the growth and production of several varieties of irrigated rice with biochar from different source. The experimental design used in this study was a split plot design with 2 factors. The first factor is: The provision of various sources of biochar with 5 levels of treatment: No biochar, rice husk biochar, coconut shell biochar, oil palm empty bunch biochar and jengkol skin biochar. The second factor was: Ciherang, Hipa 19, Inpari 33. Parameters observed were plant height (cm), number of panicles, weight of 1000 grains (g  and soil analysis. The results showed that the use of several varieties of lowland rice on the growth and production of irrigated rice had a significant effect on the height of rice plants from 6-9 WAP. The use of several varieties of  rice such as Ciherang, Hipa 10 and Inpari 33 varieties showed differences in plant height starting at the age of 6 WAP. The results of the final analysis of paddy fields after being given biochar treatment experienced an increase in nutrients such as N-total, P, K and organic C in all treatments

Tujuan dari penelitian ini untuk mengetahui respons pertumbuhan berbagai bahan tanam setek nilam ( Pogostemon cablin Benth) terhadap pemberian IBA (Indole Butyric Acid). Penelitian ini dilaksanakan di lahan rumah kasa Fakultas Pertanian Universitas Sumatera Utara, Medan dari bulan April sampai dengan September 2016. Penelitian menggunakan Rancangan Acak Kelompok dengan 2 faktor perlakuan. Faktor pertama adalah bahan tanam setek (setek batang atas, setek batang tengah dan setek batang bawah) dan faktor kedua yaitu konsentrasi IBA (0; 100; 200; dan 300 ppm).Terdapat 12 kombinasi perlakuan dan diulang 3 kali. Peubah yang diamati yaitu persentase setek hidup, umur muncul tunas, jumlah tunas, panjang tunas, bobot basah tajuk, bobot basah akar, volume akar, bobot kering tajuk dan bobot kering akar. Data dianalisis dengan menggunakan uji F 5% dan dilakukan uji lanjut dengan Duncan’s Multiple Range Test pada taraf α = 5%.Hasil penelitian menunjukkan bahwa perlakuan bahan tanam setek berpengaruh nyata terhadap persentase setek hidup, umur muncul tunas, jumlah tunas, panjang tunas, bobot basah tajuk, bobot basah akar, volume akar, bobot kering tajuk dan bobot kering akar. Perlakuan konsentrasi IBA berpengaruh nyata terhadap persentase setek hidup, jumlah tunas, panjang tunas, bobot basah tajuk, bobot basah akar, volume akar, bobot kering tajuk dan bobot kering akar.Interaksi anatara kedua perlakuan tersebut berpengaruh nyata terhadap persentase setek hidup, bobot basah tajuk, bobot basah akar, volume akar, bobot kering tajuk dan bobot kering akar
