Abstract

Gandum di daerah tropis mempunyai potensi pengembangan di dataran medium.Silikon dapat mengurangi cekaman panas pada gandum di dataran medium, sementara kompos diharapkan dapat menjadi substitusi pupuk silikon. Penelitian ini bertujuan untuk mengetahui pengaruh interaksi antara pupuk silikon dengan kompos terhadap pertumbuhan dan hasil tanaman gandum (Triticum aestivum L.) di dataran medium. Penelitian ini dilaksanakan pada bulan April 2016 – September 2016 di kebun percobaan Ciparanje Fakultas Pertanian Universitas Padjadjaran, Jatinangor, Sumedang. Rancangan percobaan yang digunakan adalah rancangan acak kelompok sementara rancangan perlakuan adalah faktorial yang terdiri dari 6 taraf dosis silikon 50 kg ha-1, 100 kg ha-1, 150 kg ha-1, 200 kg ha-1, 250 kg ha-1, 300 kg ha-1 dan 2 taraf dosis kompos 3 ton ha-1 dan 6 ton ha-1 yang diulang sebanyak 3 kali. Hasil penelitian menunjukkan terjadi interaksi antara aplikasi pupuk silikon organik dengan kompos terhadap hasil (bobot biji pertanaman). Aplikasi pupuk silikon organik 250 kg/ha disertai kompos 3 ton ha-1 menghasilkan bobot biji per tanaman tertinggi sebesar 6,39 g per tanaman, sedangkan pada pada aplikasi kompos 6 ton ha-1, hasil tertinggi ditunjukkan pada aplikasi pupuk silikon organik 200 kg ha-1 dengan hasil sebesar 6,09 g per tanaman.Kata kunci: gandum, silikon, kompos

Abstract

The growth of wheat plants can be determined by measuring leaf area index and net assimilation rate. Both measurements require leaf area data. Measurement of leaf area of wheat in Indonesia requires a method that is not only accurate, but also easier and cheaper. One of them is the regression method. The purpose of this study was to determine an accurate regression equation model in predicting wheat leaf area. This research was conducted from March to June 2021 at the Experimental Station and Plant Production Technology Laboratory, Faculty of Agriculture, UNPAD, Jatinangor, Sumedang. The materials used in this study were various leaf area printing papers from wheat plants aged 14 days after planting (DAP), 28 DAP, and 42 DAP. The regression equation was assembled from the relationship between leaf area with leaf width and length, then compared with the actual leaf area that measured by scanning. The results showed that the linear, quadratic, cubic, and logarithmic regression equations had a coefficient of determination of more than 90% to predict leaf area, at the age of 14, 28, and 42 DAP, as well as all plant ages. Quadratic regression had a limit of data that can be entered, so it needed circumspection in using the formula. Cubic regression tended to have better accuracy in predicting leaf area at 14, 28, and 42 DAP, but the accuracy was the same as other regression equations at all plant ages.

Abstract

Biofertilizers contain bacteria that can offset the use of inorganic fertilizers. However, using bacteria as biofertilizers also requires carrier materials such as bran, compost, and Azolla flour to maintain the viability of the bacteria before being transferred to the soil. This study aimed to determine the effect of consortium biofertilizer with different carriers and doses of NPK (nitrogen, phosphorus, potassium) fertilizer on the growth and yield of upland rice on Inceptisols from Jatinangor. This study used a randomized block design with two factors: the carrier of consortium biofertilizer (compost, rice bran, and Azolla) and the dose of NPK fertilizer (0%, 50%, and 100%). The experimental results showed no interaction between the consortium's biofertilizers with carrier and NPK fertilizer doses on plant height, number of tillers, weight of rice grain, and weight of 100 grains of upland rice plants. The independent factor of biological fertilizer with carrier material significantly affected plant height, and the independent factor of single NPK fertilizer significantly affected plant height, number of tillers, and rice grain weight.
