    Potential of Hybrid Maize Varieties for Feed and Food on Irrigated Land in Supporting Cattle Development and Food Diversification
    (Badan Penelitian dan Pengembangan Pertanian, 2013) Baiq Tri Ratna Erawati; Ahmad Suriadi; Andi Takdir
    Development of cattle in West Nusa Tenggara, are generally constrained by the limited availability of forages, especially in the dry season I and II. Farmers in West Nusa Tenggara generally grow maize in both dry season 1 and dry season 2. The purpose of this study was to determine the extent of the potential of hybrid verities of maize for food and fodder in the irrigated land in supporting the development of cattle and food diversification. Experiment was conducted with five seeds per hole and was gradually cut at a certain times until two plants/hole remain during growth period. The experiment was conducted in farmers’ fields, of West Lombok West Nusa Tenggara from May to August 2012 and was laid out using a randomized block design, with four treatments of hybrid maize varieties (Bima 2, 3, 4 and 5) and replicated six times. Cutting one plant/hole was done at 30 DAS (days after sowing), 45 and 75 DAS (young corn). Trimming leaf of two, remaining plants/hole below cob was done at 90 DAS and cutting stem of plant above cob at 100 DAS and harvest at 105 DAS. The results showed that there is no significant difference of plant height between four varieties at 30, 45 and 75 DAS. The percentage of growth was significantly different at 30 DAS where the highest percentage of growth was achieved at Bima 4 and Bima 5 by 64% and 66% respectively, and at 75 DAS for Bima 5 and Bima 4 by 65 and 73% respectively, while percentage of maize growth was no significantly different at 45, 90 and 100 DAS. The highest fresh biomass at 30 DAS was found at Bima 4 and 5 by 0.46 and 0.44 t/ha respectively, at 75 DAS was found at Bima 2 and 3 by 10.92 and 10.11 t/ha respectively, at 100 DAS (cut the stem above) was found at Bima 5 by 8.67 t/ha, whereas there was no significantly different of biomass at 45 and 90 DAS. The highest yield of young corn was achieved by Bima 5 for 26 389 young cobs which was raise an additional revenue for farmer of Rp. 5,277,857. Highest productivity was achieved by Bima 5 and Bima 4 for 8.65 t/ha and 8.05 t/ha respectively. In term of total biomass, variety of Bima 5 can feed for 2 cattle for 11 months with feeding weight of 40 kg/day/cattle. This technology may be used for developing a model of maizecattle integration system in an irrigated land especially in NTB Indonesia.
