Abstract

Maize is one of the food crop commodities that can take a role in the development of the agricultural sector. The purpose of this research was to know the effect of pyraclostrobin and nitrogen on the maize plant. The experimental design used in this study was a factorial completely randomized block design with three replications. The first factor was pyraclostrobin (P) that consisted of P0 = no pyraclostrobin application, and P1 = foliar spray of pryraclostrobin 400 mL/ha. The second factor was nitrogen application (N) that consisted of N0 = without N fertilizer, N30 = 30 kg N/ha, N60 = 60 kg N/ha, N90 = 90 kg N/ha, and N120 = 120 kg N/ha. The data was focused on the plant height, flowering and earing age, protein and amylose content of the seed, respectively. Data were analyzed by variance analysis followed by. analysis of the least significant difference (LSD) at the level of 5%. Nitrogen application increased protein content but reduced amylose content. Pyraclostrobin application that significantly increased the amylose content even in the high nitrogen application dosage

Abstract

One of the important stages in chili breeding is the multi-location test. The lowlands became one agroecology in the chili multi-location test because most farmers, especially in Sumatra, plant chilies on the lowlands after the rice planting season. The purpose of this study was to understand the qualitative and quantitative characteristics of chili genotypes in a lowland area. The experiment was arranged in a single-factor randomized complete block design (RCBD) with three replications. The chili genotypes evaluated were four test lines and six check varieties. The quantitative data were statistically analyzed using analysis of variance (ANOVA) followed by evaluation of genotype means using the least significant difference (LSD) tests by SPSS Statistics software. The results showed that the check variety having the lowest productivity was CH3 (1.19 tons ha-1) and the highest was Elegant (4.55 tons ha-1). The productivity of four genotypes from IPB were significantly different from the CH3 and Imperial 10 varieties, but not significantly different from Baja (2.96 tons ha-1), Balebat (3.87 tons ha-1), Elegant (4.55 tons ha-1) and Gada (3.04 tons ha-1) varieties. This research shows that the four genotypes from IPB have the potential to become new superior varieties. Keywords: Lampung; multi-location; plant breeding; varieties
