Abstract

Mardian I, Suriadi A, Widiastuti E. 2020. intercropping of soybean and maize for land optimization on farming system in low lands with dry climate in Bima regency. In: Herlinda, S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober.pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).An intercropping farming system of soybean and maize was studied to determine to what extent effects of the system on growth, yield, income and land use efficiency. This study was conducted at Usaha Baru farmer’s group in Nggembe Village, District of Bolo, Bima Regency in 2019. The study was conducted in 1 ha land where 3 treatments were applied, namely soybean monoculture, intercropping of soybean and  maize and maize monoculture. Plant spacing of 40x10 cm of Dena 1 variety of soybean at monoculture cropping pattern was applied. Intercropping pattern of soybean and maize with a ratio of 50%: 50%, with spacing of 20x30 cm and 40x35 cm, respectively. Monoculture of maize with plant spacing of 70x20 cm of Nasa-29 variety was applied. The parameters observed were agronomic performance, yield performance, data of farming input and output as well as land equality ratio (LER) and competitive ratio (CR) values. The results showed that the agronomic performance of the intercropping of soybean and maize was significantly different from monoculture. The yield performance showed a significant difference between the intercropping of soybean maize and monoculture system. The LER and CR value were 1.67 and 0.90 respectively. However, the income level of the intercropping system was higher than the monoculture of soybean and maize which is shown in the profit value of the intercropping was  Rp. 15,350,260 and R/C 2.57 and B/C 1,57.

Abstract

Sugianti T, Hadiawati L, Suriadi A, Sulistyawati Y.  2020. Utilization of POC Biourine plus natural pesticide to increase shallot yield under furrow and sprinkler irrigation of dryland east Lombok, NTB province. 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).The use of local resources as fertilizers and naturalpesticides (pesnab) is one of the shallotcultivationpracticesthat were environmentally friendlyin dryland. This study aims to measure the increase in shallot yield by the application of Biourin liquid organic fertilizer (POC) mixed with naturalpesticides underthe sprinkler irrigation system. The field experiment was carried outatSandubayadryland (46 masl)ofPringgabaya District, East Lombok Regency, West Nusa Tenggara (NTB) from June to November 2018. The experiment used a factorial randomized block design with two factors and three replications. The first factor wasof shallotsgrown in the furrowirrigation system (A) and the sprinkler irrigation system (B). The second factor was the spraying of POC biourin plus soursop leaf extract (P1), POC biourin plus neem leaf extract (P2), POC biourin plus tobacco leaf extract (P3), POC biourin without extract as a control (P0). The results of the experiment showed that the effect of the treatment’s interaction weresignificantly different on the parameters of plant height at 20 and 60 days after planting (DAP), plant’sfresh weight, sundried weight loss, and shallot bulb’sseed weight. The fresh weight of shallots was higher in the sprinkler irrigation system (3.27 kg / m2) than in the furrowirrigation system (2.70 kg / m2). The highest dry weight of shallots was obtained in the application of POC biourin plus soursop leaf extract in the sprinkler irrigation system at 1.79 kg/m2whichwas 37.99% highercompared to the control.
