Plants that can be used as pesticides are Gadung tubers. Gadung tubers contain cyanide acid to kill armyworm pests because they contain dioscorin toxins which can cause nervous disorders. The purpose of this study was to determine the effect of Gadung tuber extract (Dioscorea hispida) on Caterpillar mortality (Spodoptera exigua) in Shallot plants. This type of research is experimental research. This study used a completely randomized design (CRD). The sample used was 5 caterpillars (Spodoptera exigua) in each polybag with 5 repetitions for each concentration of Gadung tuber extract, namely 0%, 0.5%, 1.0%, 1.5%, 2.0% and 2.5%, so the total Caterpillar used was 150 Caterpillars. Gadung tuber extraction was carried out by maceration method with methanol solvent. Data were analyzed using a one-way analysis of variance at the 95% significance level, followed by DMRT (Duncans Multiple Range Test). The results showed that the Gadung tuber extract had a significant effect on the mortality of caterpillars (Spodoptera exigua) because the F count was greater than the F table (45.40>2.62), and the DMRT test results showed that the optimal concentration of Gadung tuber extract was 2.5%. Therefore, it can be concluded that the extract of Gadung tuber (Dioscorea hispida) affects the mortality of Caterpillars (Spodoptera exigua) in Shallots (Allium cepa).

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.

The objective of this study was to evaluate alternative methods to overcome dormancy in Leucena (Leucaena leucocephala) seeds. The seeds were collected from four different matrices and subsequently submitted to different treatments with mechanical scarification and immersion in water and soft drink at different times (0, 6, 24 and 48 h) at 25 ºC. A completely randomized design was used, consisting of 14 treatments composed of four replications containing 50 seeds each. The variables analyzed were: Germination at the first count (G); Normal Seedlings (PN); Hard or Dormant Seeds (SD); and Germination Speed Index (IVG). The results increased higher percentages of germination (G) in the T1 treatment (mechanical scarification) with 46.7 and 43.2% of normal seedlings (PN) with 43.2% and IVG of 41.9. However, when observing only the treatments submitted in different combinations, it was noted that the treatments T8 (Mechanical scarification and immersion in soda for 6h at 25 ºC) and T2 (Mechanical scarification and immersion in distilled water for 6h at 25 ºC) presented a germination of 44.7 and 39.7%, respectively. Thus, shorter water immersion times associated with mechanical scarification are required to obtain the highest percentage of germination and formation of normal seedlings.

The evaluation of seed priming methods on the seed and seedling performance of soursop was conducted January 9 to April 3, 2019 in San Nicolas, Ilocos Norte, Philippines.  The study was conducted to investigate the effect of seed priming methods  capable of breaking dormancy; improve germination rate; determine the seed vigor of soursop; and identify the best seed priming method that provide better seedling performance. The experimental  treatments (unprimed and three priming methods, hydropriming, halopriming and hormonal priming) were laid out in Completely Randomized Design with three replications. A     total of 20 polyethylene bags were used per treatment per replication with one seed sown in every bag. Alternative way to improve seed and seedling performance is the use of these seed priming methods. The seed and seedling performance of soursop were significantly affected by priming methods. Primed seeds had higher percentage germination rate (PGR) than unprimed seeds. But numerically, the highest PGR was hydropriming. Hormonal priming produced significantly taller seedlings at 10 and 40 days after emergence (DAE) than unprimed seeds and more leaves per seedling at 30 to 50 DAE. Hormonal, hydropriming and halopriming produced significantly higher fresh weight of seedlings than unprimed seeds.

Chlorophyll is a pigment of photosynthesis which is also efficacious as a cure for brain, lung, and oral cancer, and can be used as a disinfectant, antibiotic and dietary supplement, while carotenoids are useful as antioxidants. The content of the two pigments is strongly influenced by the age of the plant, especially for vegetable crops used in leaves such as cowpea (Vigna unguiculata (L.) Walp.). The purpose of this research is to know the pattern of chlorophyll content and carotenoid of cowpea leaf during the growth phase and to know the age of the right plant for harvesting cowpea so that the highest chlorophyll and carotenoid content is obtained. Cowpea seeds obtained from seeds are added then planted in pots containing ready-made planting media in the greenhouse. Chlorophyll and carotenoid analyzes were performed at different plant ages from 1 to 11 weeks. The research design used is Completely Randomized Design. Data were analyzed using variance analysis and continued with Duncan test at 95% significance level. The results showed that the highest chlorophyll and carotenoid content was produced by the cowpea leaf in the vegetative phase or before the flowering time. The highest chlorophyll content was obtained at 4WAP (weeks after planting) of age crop, while the highest carotenoid content was obtained in 3WAP.

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.

Grains, brans, and vegetable meals may contain non-starch polysaccharides (NSP), which increases viscosity in the gastrointestinal tract (GIT) and interfere with the digestion and absorption of nutrients. This study aimed to evaluate the performance and determine the metabolizable energy of a sorghum-based broiler diet with and without the supplementation of an enzymatic complex. The experiments were conducted in a completely randomized design with 1200 chickens, using sorghum-based feed with and without the addition of 50 g of enzyme-CCE complex (?-glucanase and ?-xylanase), and with two levels of metabolizable energy (ME kg-1): ME; ME + CCE; reduced ME (-50 kcal kg-1); and reduced ME + CCE. The data were subjected to an analysis of variance and the means were compared using a Tukey’s test at the 5% significance level. At 42 and 47 days of age, the living weight of the birds fed with the reduced ME was low, while birds fed with reduced ME + CCE had the same weight as those fed with other energy diets (ME and ME + CCE). Feed conversion was poorest at 47 days of age for the birds on reduced ME diet. In the metabolic test (with fattening diets) to determine AME and AMEn, the reduced ME diet had the lowest result, confirming the effect of the addition of enzymes. The addition of CCE to sorghum-based diets provides enough enzymatic activity to increase the metabolizable energy of the diet (50 kcal of AME) and influence the growth performance of broilers at the slaughtering age.
