This study aimed to determine the productivity and nutrient content of three grasstypes with or without rubber trees shading. It was conducted in May-September 2020at Sangga Buana Village, Seputih Banyak, Central Lampung and Animal Nutrition andFood Laboratory, University of Lampung. This study used nested design with two factorsof rubber trees shaded and grass types with six replications. Both factors were shadedconditions: N0 (land without shade) and N1 (land under rubber trees shade); and grasstypes: elephant grass (A1); setaria (A2); and odot (A3). The results showed the shadeddecreased (P<0.05) leave length of each grass compared to non-shading conditions.Grass under the shade decreased their production and odot grass showed the lowestproduction (P<0.05). The number of tillers and plant height under the shade decreasedsignificantly (P<0.05) on elephant grass and setaria grass. Leaf width under the shadedecreased significantly (P<0.05) on setaria and odot grass. The shaded effected (P<0.05)nutrient content on elephant grass, setaria, and odot. It was concluded that Setariagrass (Setaria sphacelata) had the best productivity under the shaded based on yield.The nutrient content of each grass varied depending on the ability of the grass to adaptto shaded conditions.

Rubber tree production is reduced by weeds that compete for environmental resources; therefore, the timing and duration of weed control influences weed interference. The objectives of this study were to evaluate the growth of rubber tree (Hevea brasiliensis) plants, to determine the critical period for weed control, and to evaluate the growth recovery of rubber trees that coexisted with weeds for different periods of time after planting. Two groups of treatments were established under field conditions in the first year of the investigation: one group contained crescent periods of weed infestation, while the other contained crescent periods of weed control, also including a weed-free check and a total weedy check. In the second year of the investigation, the weeds were totally controlled. Urochloa decumbens was the dominant weed (over 90% groundcover). Crop growth was greatly reduced due to the weed interference. Plant height decreased more rapidly than did any other characteristic. Plant height, leaf dry mass, and leaf area decreased by 99%, 97% and 96%, respectively, and were the most reduced characteristics. Plant height also recovered more rapidly than did any characteristic when the period of weed control was lengthened. However, stem dry mass increased by 750%, making it the most recovered characteristic. The critical period for weed control was between 4 and 9½ months after planting in the first year; however, the rubber trees showed an expressive growth recovery when the weeds were controlled throughout the second year.

Potted chrysanthemums as one of high-demand potted ornamental plants are mostly cultivated using inorganic fertilizers. The organic fertilizers use as an alternative and complementary to inorganic fertilizers on potted chrysanthemum cultivation needs to be studied further. This study aims to determine the response of inorganic and organic fertilizer to agronomic characters of three potted Chrysanthemum varieties. The research was carried out in West Sumatra AIAT’s greenhouse from October to December 2020 using split-plot design with three replications. The main plots were fertilizer treatments (control, inorganic fertilizers, Bio-urine organic fertilizers) and sub-plots consisted of three potted chrysanthemum varieties (Armita, Avanthe, and Naura). Bio-urine organic fertilizers nutrient content N, P and K. The results showed that agronomic character of plant height, leaf length, leaf width, and the number of internodes resulted from type of fertilization treatments were significantly different. The highest plant height, leaf width, and number of internodes were significantly achieved in inorganic fertilizers then followed by Bio-urine organic fertilizers and control. The highest growth for the characters of plant height, stem diameter, leaf length, leaf width, petiole length, and flower diameter were attained from Avanthe. The interaction between fertilizers types and varieties was not significantly different in all observed characters.

Few reports have been presented on nutrient cycling in rubber tree plantations (Hevea brasiliensis Muell. Arg.). This experiment was carried out to evaluate: the effect of K rates on the amount of nutrients transfered to the soil in a 13-year old Hevea brasilensis RRIM 600 clone plantation, nutrient retranslocation from the leaves before falling to the soil, and nutrient loss by dry rubber export. The experiment started in 1998 and potassium was applied at the rates of 0, 40, 80 and 160 kg ha-1 of K2O under the crowns of 40 rubber trees of each plot. Literfall collectors, five per plot, were randomly distributed within the plots under the trees. The accumulated literfall was collected monthly during one year. The coagulated rubber latex from each plot was weighed, and samples were analyzed for nutrient content. Increasing K fertilization rates also increased the K content in leaf literfall. Calcium and N were the most recycled leaf nutrients to the soil via litterfall. Potassium, followed by P were the nutrients with the highest retranslocation rates. Potassium was the most exported nutrient by the harvested rubber, and this amount was higher than that transfered to the soil by the leaf literfall.

Passionflower is a member of Passifloraceae family, it can be used as medicinal and ornamental plants in addition to its consumption as fruit in the world. Guava (Psidium guajava L.) fruits, which has a rich nutrient content, are consumed both fresh and processed. Passionfruit and guava plants, which can only be cultivated in temperate southern coasts in our country, have gained commercial importance because of the fruits' export potential, high medical importance and nutrient. This study was carried out to determine the effects of some bioactivator applications on the criteria of sapling growth and development of passionflower and guava plants. The experiment was conducted between 2018-2019 under greenhouse conditions. Saplings obtained from seed germination in Akdeniz University Faculty of Agriculture Research and Experiment Area were used as plant material. 3 different commercial preparations called Messenger, Crop-set and ISR-2000 were used as bioactivators. Plant height (cm), stem diameter (mm) and number of leaves (number / plant) were measured weekly, in order to determine the effect of the applications on the growth and development of saplings. At the end of the study, it was determined that the highest average plant height (10.17 cm), stem diameter (13.53 mm) were obtained in ISR-2000 application. The highest average plant height (11.93 cm), stem diameter (16.44 mm) and number of leaves (9.07 units / plant) were obtained from Messenger application in guava plant. When the results obtained are evaluated, it is recommended that ISR-2000 bioactivator can be applied in passionflower sapling cultivation and Messenger bioactivator can be applied for guava sapling cultivation.

Cuscus is an arboreal animal whose habitat is in the forest with the type of food consumed are fruits, leaf shoots, and agricultural plants. Animal manure can also be used as organic fertilizer for forage plants. This study aims to determine the growth response of Setaria grass (Setaria sphacelata) given a dose of cuscus manure fertilizer with banana and avocado consumption. The study was designed in a CRD with 3 treatments. The treatments were P0 = without fertilizer (100% soil), P1 = 40 g/polybag of cuscus manure with banana consumption, and P2 = 40 g/polybag of cuscus manure with avocado consumption. Planting is done by pols on polybags measuring 30 x 25 cm. The results showed that the highest plant height of Setaria grass was found in P2 with an average of 101.70, then P1 was 101.47 and P0 was 71.16 cm/week. The results were the same for the number of leaves and tillers, P2 showed significantly higher results (P<0.05), followed by P1 and control. The application of organic fertilizer of cuscus manure with the consumption of bananas and avocados can increase the growth of Setaria grass.
