Abstract

Corn is an important food crop in Indonesia. Plant expansion has been hampered by soilacidity problem and the protein content of many corn varieties was low. This research initiates development of soil-acid-tolerant corn with highquality- protein content. Research was done on 12 factorial treatments and 3 replications as blocks in RCBD. The first factor was corn populations: Toray-1(G1), Toray-2(G2), GS- 5(G3) and GS-10(G4). The second factor was fertilizations: P1(69 kg N+36 kg P2O5+15 kg K2O per ha)); P2(115 kg N+54 kg P2O5+30 kg K2O per ha); and P3(161 kg N+72 kg P2O5+45 kg K2O per ha). The observed variables consisted of several agronomic traits, including the protein content. Results indicated that the corn populations, in general, showed good agronomic traits. The differences were mostly between populations, not between fertilizations, and no interaction was observed. The yield potential ranged from 4.25 to 6.47 ton dry seeds per ha. The protein content of seed resulted from cross ranged from 9.84% to 11.30%, as compared to the parents of 9.11% and 12.62%. This research concludes that genetic factors play an important role as confirmed by heritability estimate (h2)=0.75.Keywords : Corn, protein, acid-soil, tolerance

Abstract

Halimi ES, Hasmeda M, Amelia P, Dewa TPA, Pranjaya I. 2020.  Seed production growth and yield evaluation several open-pollinated maize accessions of unsri j1-j8 at sub-optimal dry land. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Effort to develop open pollinated varieties of maize should be put into a priority to give more benefit to the farmers.  Production of their seeds are also important, since Maize can only be commercially grown from the seeds.  This research was carried out in two-seasons, to produce seeds in 2017/2018  and then planted them for evaluation in 2018/2019 for evaluation.  Research utilized eight Maize accessions called as Unsri-J1 to J8. Research to produce seeds was done by using ear to row method in 3 replication-plots, each consisted of  10 rows with planting distance 75cm x 25 cm.   Research to evaluate growth and yield were done in the field, incorporation with local farmers.  Analysis data were done by using  a randomized block design in nested scheme consisted of 5 plot-samples as blocks. Result of this research indicated that seed production of  Unsri-J1 to J8 in sub-optimal dry land could be done, especially for the Unsri-J1 and J3 accessions that beside showed consintency in growth, also were  able to produce 6.4 and 5.5 ton dry seeds/ha.   Their growth evaluation also showed greater posture and having earlier period of  anthesis, while their yield evaluations, in general, were about equivalent, even more for Unsri-J1 tended to have higher yield than control variety.
