Forage is the main source of feed for ruminants. Forage consists of two types, namely grass and legumes. Leguminosa is a type of forage as a source of protein. One type of legume that is well known by breeders in Indonesia is lamtoro (Leucaena leucocephala cv. Tarramba). This study was aimed to produce candidate mutants of lamtoro drought resistant to acid stress conditions. The experiment in this study used an unbalanced completely randomized design with 6 treatments of 740 different replications based on different sources of lamtoro plant mutants at different levels (P0: 0 n= 89, P1: 100 gy n= 82, P2: 200 gy n= 153, P3:300 gy n=120, P4: 400 gy n= 244, P5: 500 gy n= 52). Variables observed included plant height, number of stalks, leaf loss and stem diameter. The results showed that lamtoro plants irradiated with gamma rays at a level of 200 gy-500 gy were significantly higher than 100 gy irradiation at 10 and 12 days watering, but the diameter of the plants was larger at 100 gy irradiation. It can be watering intervals of 10 days and 12 days on the parameters of height and stem diameter showed that gamma rays irradiation of 400 gy resulted in dry-resistant lamtoro mutant candidates under acid stress condition.

This study aims to determine the effect of using different levels of thinner olive oil (extra virgin olive oil) on the viability and abnormality of spermatozoa and the pH of the semen of duroc pigs. The research took place in September 2020 in Noenebu, Tapenpah Village, Insana District, North Central Timor Regency, and the Laboratory of the Faculty of Agriculture, University of Timor. This study used a completely randomized design (CRD) with 4 treatments and 5 replications. Treatment R1 consist of 10% tris solution, 10% olive oil, 80% semen; R2 treatment consist of 15% tris solution, 15% olive oil, 70% semen; R3 treatment consist of 20% tris solution, 20% olive oil, 60% semen, and R4 treatment consist of 25% tris solution, 25% olive oil, 50% semen. The results showed that the effect of different treatments was very significant (P <0.01) on the viability of spermatozoa. The mean spermatozoa viability of each treatment was R1 of 89 ± 2.57%, R2 of 76.9 ± 12.51%, R3 of 62.8 ± 3.11%, and R4 treatment of 41.2 ± 15, 38%. The spermatozoa abnormalities were significantly different (P <0.05). Where the abnormality of the spermatozoa in treatment R1 was 8.8 ± 1.30%, R2 was 10.4 ± 1.67%, R3 was 11.6 ± 1.81%, and R4 was 14.4 ± 3.78%. The degree of acidity (pH) of the semen was not significantly different between treatments. The pH value of each treatment was R1 of 7.92 ± 0.83, R2 of 8.04 ± 0.54, R3 of 7.96 ± 0.39; and R4 treatment of 8.06 ± 0.64. It can be concluded that the addition of 10% to 20% olive oil can maintain the viability and abnormality of duroc boar male spermatozoa. However, the use of olive oil up to 20% does not affect to degree of acidity of the semen produced.

ABSTRACT Cultivation using brackish waters can result in nutritional and metabolic imbalances in several plant species, consequently reducing the production of dry matter (DM) and accumulation of toxic ions (Na+ and/or Cl-) in plants. We evaluated the DM production, and nutrient and inorganic solute (Na+ and Cl-) content in green onion plants (cv. Todo Ano Evergreen - Nebuka) under different levels of nutrient solution salinity in combination with circulation frequencies of this solution. Two experiments were conducted in a hydroponic system, using a completely randomized design, in a 6 × 2 factorial scheme, with five replicates: six levels of nutrient solution salinity (1.5, 3.0, 4.5, 6.0, 7.5, and 9.0 dS m-1) and two solution circulation frequencies (twice and thrice a day). In Experiment I, the evapotranspired depth was replaced using brackish water that was used to prepare each of the salinity levels (used exclusively), whereas in Experiment II, brackish water was used only to prepare each of the salinity levels and public water was used (electrical conductivity [ECw] = 0.12 dS m-1) for replacement in all treatments. The increase in the nutrient solution salinity reduced the production of DM and accumulation of nutrients; the reductions were more pronounced when brackish waters were used exclusively (Experiment I). However, the circulation of solutions thrice a day resulted in the harmful effects of the salinity effect. Replacing the evapotranspirated blade with water supply (Experiment II) mitigated the deleterious effects of salinity. Moreover, three circulations of the nutrient solution daily resulted in lower accumulation of inorganic Na+ and Cl- solutes and increased accumulation of nutrients N, P, K+, Ca2+, Mg2+, and S in the culture.

The objective was to evaluate milk production, N2-fixation and N transfer, forage yield and composition (under two cutting intervals) in a silvopastoral system (SPS) with Leucaena leucocephala-Megathyrsus maximus and M. maximus-monoculture (MMM) with crossbred cows in a completely randomized design. Forage yield in the SPS was 6490 and 6907 kg DM ha−1 for cutting intervals (CI) of 35 and 50 days. Forage yield for the MMM was 7284 and 10,843 kg DM ha−1, and forage crude protein (CP) was 29.0% and 26.1% for L. leucocephala, harvested at 35 and 50 days, respectively. CP for the associated M. maximus was 9.9% and 7.8% for CI 35 and 50 days, respectively, and for MMM was 7.4% and 8.4%, harvested at 35 and 50 days. Milk production was 4.7 kg cow−1 day−1 for cows grazing MMM and 7.4 kg cow−1 day−1 under SPS. Nitrogen fixation in L. leucocephala (%Ndfa) was estimated to be 89% and 95%, at 35 and 50 days, with an N2 transfer to the associated grass of 34.3% and 52.9%. SPS has the potential to fix and transfer important amounts of N2 to the associated grass, and increase forage CP content and milk production.
