Abstract The purpose of this study was to determine the interaction effect of the use of mycorrhizal biofertilizers and varieties to increase the production of organic patchouli on the Entisol soil of Aceh Besar. This study used a factorial randomized block design with three replications. The first factor observed was mycorrhizal biofertilizer from the various genus, namely Glomus mosseae, Gigaspora sp. and the mixed genus of Glomus mosseae and Gigaspora sp. While the second factor is the use of varieties, namely Tapak Tuan and the Lhokseumawe variety. The results showed that the best interactions on the growth and production, P205 uptake, and oil content were found in the mixed mycorrhizal genus (Glomus mosseae + Gigaspora sp.) with the Tapak Tuan variety. From the patchouli alcohol content test results, the best results were obtained in a combination of mixed mycorrhizal biofertilizers and the Tapak Tuan variety by 30%.

AbstractIn recent years, producers of agricultural products have increased the use of chemical fertilizers per unit area. The goal of this research was to analyze the interaction of genotype in treatment (NPK fertilizer) on grain yield, protein content, oil content, and the starch content on 13 maize hybrids using analysis by the model of additive and multiplier effects AMMI and to evaluate genotypes, treatments, and their interactions using biplot in Hungary. Treatments include NPK0 (N: 0 kg/ha, P2O5:0 kg/ha, K2O: 0 kg/ha), NPK1 (N: 30 kg/ha, P2O5: 23 kg/ha, K2O: 27 kg/ha), NPK2 (N: 60 kg/ha, P2O5: 46 kg/ha, K2O: 54 kg/ha), NPK3 (N: 90 kg/ha, P2O5: 69 kg/ha, K2O: 81 kg/ha), NPK4 (N: 120 kg/ha, P2O5: 92 kg/ha, K2O: 108 kg/ha), NPK5 (N: 150 kg/ha, P2O5: 115 kg/ha, K2O: 135 kg/ha) in four replications based on complete randomized block design in 2019. The NPK fertilizer effects indicate that the fertilizers are different on yield genotype. AMMI analysis showed that there was a significant difference between genotypes, treatment, and the interaction effect of genotype * treatment at one percent. Besides, the maximum yield had Loupiac and NPK3 on grain yield, Loupiac and NPK2 on oil content, P0023, and NPK3 for starch content, DKC 3/ES4725 (DKC4725) and NPK3 for protein content. Also, GGE biplot analysis indicates that had maximum grain yield in Loupiac, protein content in P9978, oil content in MV Maronetta, and starch content in Sushi.

Among the traits that may add commercial value to maize (Zea mays L.), those related to nutritional quality, specially protein and oil content, are of great interest to the feed industry. The objective of this work was studying the variability of protein and oil content, as well as yield, in a group of maize testcrosses. One hundred and twenty S1 families of the ESA23B maize population were crossed with two testers, an open-pollinated population (BR108) and an exotic line (CML269). Testcrosses were evaluated at two locations under a completely randomized block design with three replications. Ear and grain yield, protein and oil content were evaluated. The three-way interaction location x tester x progeny was significant for all traits, except for oil content. Differences among progenies were detected for all traits. Testcross means varied from 8.40% to 11.82% for protein content and from 3.77% to 5.10% for oil content. Hybrids with similar or superior means to the best check were identified for protein content, ear yield, and grain yield. Estimates of the interpopulation additive variance ranged from 0.553 to 1.124 for protein content; 0.034 to 0.057 for oil content (percent data); 132.13 to 521.74 for ear yield and 116.33 to 381.73 for grain yield (data in grams per plant). The population ESA23B can potentially be improved for all the traits studied. Associations among traits were weak, thus concomitant selection of quality and yield can be feasible.
