Abstract

Sterilisasi dan komposisi media merupakan faktor penentu dalam menghasilkan inokulan mikoriza yang berkualitas. Penelitian ini bertujuan untuk mendapatkan kualitas inokulan konsorsium FMA dan MHB yang terbaik dengan merekayasa media tanam dan metode sterilisasi. Percobaan telah dilakukan di rumah kaca menggunakan Rancangan Acak Kelompok (RAK) pola faktorial yang terdiri atas dua faktor perlakuan. Faktor pertama adalah sterilisasi media yang terdiri atas: (1) sterilisasi melalui pencucian dengan air, (2) sterilisasi menggunakan autoklaf, (3) sterilisasi dengan NaOCl, dan (4) sterilisasi dengan irradiasi gamma. Faktor kedua adalah komposisi media yang terdiri atas: (1) 100% zeolit, (2) 75% zeolit : 25% arang sekam, dan (3) 50% zeolit : 50% arang sekam. Hasil penelitian menunjukkan bahwa terdapat interaksi antara sterilisasi dan komposisi media terhadap jumlah spora MA, namun tidak berpengaruh terhadap nisbah pupus akar sorgum. Sterilisasi media secara mandiri berpengaruh terhadap populasi MHB. Perlakuan sterilisasi irradiasi gamma + komposisi media 75% zeolit : 25% arang sekam merupakan perlakuan yang cenderung lebih baik dalam meningkatkan jumlah spora MA, populasi MHB, dan nisbah pupus akar sorgum.

Abstract

One of the efforts to increase crop yield based in sustainable agriculture is through the utilization of microbial inoculants (biofertilizers) and soil conditioners. Biofertilizer is an ingredient that contains beneficial microbial inoculants to increase soil nutrient availability for plants. Biochar has been recognized as a soil conditioner by improving soil physical, chemical, and biological properties as well as in retaining nutrients, thereby enhancing plant growth. However, the research regarding the effect of the combination between biofertilizers and biochar on growth and yield of upland rice are still at scarce. The field experiment was conducted to determine the impact of biofertilizers and biochar on growth and yield of upland rice in Andisols at Pasir Talang village in Rancakalong district, Sumedang, West Java.  This experiment used a Randomized Block Design (RBD) consisted of six treatments and four replicates. Biofertilizers consisted of N-fixer bacteria (Azotobacter chroococum, Azospirillum sp.) and phosphate-solubilizer microbes (Pseudomonas mallei, P. cepaceae, Aspergillus niger and Penicillium sp.). The treatments were combination of biochar (2,4, and 6 t ha-1) and biofertlizers (0 and 50 kg ha-1). The result of experiment revealed that combination of biochar and biofertilizers increased the growth and yield of upland rice significantly. The application 4 t ha-1of biochar and 50 kg ha-1 of biofertilizers gave the best yield of 5,81 t ha-1.

Abstract

Analysis of the farming system is an applied science which concerns on how to use resources efficiently and effectively in agricultural business in order to get maximum results. In this analysis, one of the important aspects on agricultural production is fertilizer. Liquid compound fertilizer is a fertilizer with several advantages such as simple application, complete and balanced required nutrients, labour and time efficient, and easy to procure and store. The purpose of this study was to determine the analysis of farming system on the application of liquid compound fertilizer on sweet corn. This experiment used a Randomized Block Design (RBD) consisted of 10 treatments (8 treatments of liquid fertilizer doses, one treatment of fertilizer dosage recommendations for NPK and one control (without fertilizer)). Each treatment was repeated three times, with the total of 30 experimental plots. The results of this experiment were the application of compound liquid fertilizer provides a high relative value of agronomic efficiency and profits on corn. The treatment of 1 ¼ NPK liquid fertilizer dose gave higher RAE, R/C and B/C values compared to the control. NPK liquid fertilizer has a significant effect on the variables of soil (pH, N, P and K content) and yield components (N, P and K uptake). In general, the use of NPK liquid fertilizer can significantly increase the yield, with the highest yield on 1 ¾ dose and the yield of corn plants (18,329 kg/ha).
