“…In general, the synergy between AMF, PSB, and NPK fertilizers increase the sweet sorghum growth in saline condition.Previous study has shown that the combination of AMF, PSB, and NPK could increase the growth of sweet sorghum (Ramadhani et al 2019). Salt in growth medium affect plant growth and development because salt reduces nutrient acquisition in plants (Ruiz-Lozano et al 2012).…”

“…Sweet sorghum plant in saline condition with the AMF+PSB+25% NPK treatment showed significant increase in height, number of leaves, plant fresh weight, plant dry weight, and total P. In other treatments, 25% NPK increased all growth parameters of sweet sorghum plant. However, this study was not conducted under saline condition (Ramadhani et al 2019).…”

ABSTRACT Sweet sorghum (Sorghum bicolor (L.) Moench) is a food source and a raw material in biofuel-ethanol production. Arbuscular mycorrhizal fungi (AMF) and phosphate-solubilizing bacteria (PSB) are called rhizosphere microorganisms, which are useful microorganisms that enhance plant growth. Rhizosphere microorganisms also increase plant's resistance to environmental stress, while NPK fertilizer used on agricultural land are found to increase crop yields only. However, its continuous application has a negative impact on the environment. Therefore, this research aimed to study the synergy between AMF, and PSB with NPK fertilizer in influencing the sweet sorghum growth in saline condition. Two treatment factors were used, which are microbes combination (arbuscular mycorrhizal fungi and phosphate-solubilizing bacteria), and NPK doses without NPK, 25% NPK, 50% NPK, and 100% NPK. Furthermore, zeolite was used to grow sweet sorghum seeds individually and were maintained for one month in a greenhouse. Pots were watered with 50% seawater (freshwater: seawater = 1:1) every day to keep the moisture. Plant growth parameters were also measured, which includes AMF colonization in the roots, number of AMF spores, and PSB population in the planting medium. The combination of AMF, PSB, and NPK in sweet sorghum increased the plant height, number of leaves, plant fresh weight, plant dry weight, and total of plant P, although not always significant. AMF+PSB+25% NPK produced the highest number in all parameters. Therefore, the synergy between AMF, and PSB with NPK fertilizer is able to increase the plant growth in saline condition. Key words: arbuscular mycorrhizal fungi, phosphate-solubilizing bacteria, NPK, saline, and sweet sorghum ABSTRAK Sorgum manis (Sorghum bicolor (L.) Moench) merupakan sumber makanan dan bahan baku dalam produksi bioetanol. Jamur mikoriza arbuskular (JMA) dan bakteri pelarut fosfat (BPF) disebut sebagai mikroorganisme rizosfer, yang merupakan mikroorganisme yang berguna untuk meningkatkan pertumbuhan tanaman. Mikroorganisme rizosfer juga meningkatkan ketahanan tanaman terhadap cekaman lingkungan, sedangkan pupuk NPK yang digunakan pada lahan pertanian ternyata hanya meningkatkan hasil panen saja. Namun, penerapannya yang berkelanjutan memiliki dampak negatif terhadap lingkungan. Oleh karena itu, penelitian ini bertujuan untuk mempelajari sinergi antara JMA, dan BPF dengan pupuk NPK dalam mempengaruhi pertumbuhan sorgum manis dalam kondisi salin. Dua faktor perlakuan yang digunakan, yaitu kombinasi mikroba (jamur mikoriza arbuskular dan bakteri pelarut fosfat), dan dosis NPK tanpa NPK, 25% NPK, 50% NPK, dan 100% NPK. Selanjutnya, zeolit digunakan untuk menumbuhkan biji sorgum manis secara individu dan dipelihara selama satu bulan di rumah kaca. Pot disiram dengan 50% air laut (air tawar: air laut = 1: 1) setiap hari untuk menjaga kelembaban. Parameter pertumbuhan tanaman juga diukur, yang meliputi kolonisasi JMA di akar, jumlah spora JMA, dan populasi BPF dalam media tanam. Kombinasi JMA, BPF, dan NPK dalam sorgum manis meningkatkan tinggi tanaman, jumlah daun, berat basah tanaman, berat kering tanaman, dan P total tanaman, meskipun tidak selalu signifikan. JMA + BPF + 25% NPK menghasilkan nilai tertinggi di semua parameter pertumbuhan. Oleh karena itu, sinergi antara JMA dan BPF dengan pupuk NPK mampu meningkatkan pertumbuhan tanaman dalam kondisi salin. Kata kunci: jamur mikoriza arbuskular, bakteri pelarut fosfat, NPK, salin, dan sorgum manis

Sorghum [Sorghum bicolor (L.) Moench] is a multipurpose food crop that can adapt to climate change. Sorghum productivity can be increased by applying chemical fertilizers and arbuscular mycorrhiza fungi (AMF). This research aimed to assess the effect of AMF application and N and P concentration gradients to support Super 2 and KS sorghum accession growth. The plants were grown in a sterilized zeolite (coarse and fine) and inoculated with Glomus mosseae 40 spores per pot. The experimental design was a randomized complete block design with 40 treatments and three replications. N and P concentration gradient treatments were carried out using a dose level of fertilizer N (urea) and P (TSP) at 12,5%; 50%; 75%; 100%; and 125%. Analysis of variance was carried out using SAS 9.0 software at a level of 5%, and the results were significantly different, followed by DMRT. The application of AMF and urea 50% and TSP 75% in Super 2 accessions and urea 50% and TSP 50% in KS accessions gave the highest plant height and biomass. However, the increase in sorghum growth did not correlate with root colonization and root length, which could be seen that the highest in both accessions were obtained at urea 12,5% and TSP 12,5%. The application of AMF can significantly lower the use of urea and TSP fertilizers by up to 50% compared to a positive control (urea and TSP 100%) and support sorghum growth in both accessions.

“…However, ammonia saltpeter has a severe disadvantagefire risk and explosion hazard that causes some difficulties and restrictions of both its consumers and its manufacturers (Oxley et al, 2002;Dechy et al, 2004;Lavrov and Shedov, 2004;Sinditskii et al, 2005). For this reason, to obtain rich and qualitative harvests, it is necessary to apply balanced mineral fertilizers, i.e., containing nitrogen, phosphorus, potassium and other nutrients in reasonable ratios (Skydanenko et al, 2017;Daitx et al, 2019;Ramadhani et al, 2019). These are so-called complex fertilizers whose major characteristic is their high agrochemical value (Abramov et al, 2002;Levin and Sokolov, 2004;Pavlova, 2007;Ovchinnikov et al, 2008;Akhmad et al, 2018).…”

Ammoniac saltpeter is the most widespread in the world and effective nitric fertilizer. However, ammonia saltpeter has a severe disadvantage – fire risk and explosion hazard that causes some difficulties and restrictions of both its consumers and its manufacturers. The purpose of the present work consisted in the studying the possibility of production of NPК-fertilizers with improved agrochemical properties and a controlled ratio of nutrients N/Р2О5/К2О produced based on an ammonia saltpeter solution, ground phosphate rock, and potassium chloride. The laboratory and industrial experiments were continued using a rotatable planning method – the Box-Hunter second-order modeling technique. The article contains the research results on the regulation of nutritious elements (N/(Р2О5+K2O)) ratios in the NPК-containing fertilizers produced based on an ammonia saltpeter solution, a ground phosphate rock, and potassium chloride. The effect of independent variables – specific consumptions of ammonia saltpeter, a ground phosphate rock, and potassium chloride – was studied. The adequate regression equation of influence of these factors on an N/(Р2О5+K2O) ratio in the end products was obtained. Boundary values of the ammonia saltpeter, a ground phosphate rock and potassium chloride specific consumptions in the initial mixtures were found at which the total content of nutritious elements in the target products is from 30% to 33% and the N/(Р2О5+K2O) ratio has the optimum value (1.14 - 3.50).
