This study aims to determine the effectiveness of N2-fixing microbes contained in organic organic fertilizers at four levels of nitrogen fertilizer application in increasing the performance of oil palm seedlings. The experiment was carried out in the form of an experiment using a Randomized Block Design with 2 factors: organic organic fertilizer and nitrogen fertilizer. The first factor with three levels of treatment, namely without organic biological fertilizer, Organic fertilizer from cow dung (Agro Flower) 1 g / kg of Soil and Organic organic fertilizer (Biost) 1 g / kg of Soil. While the second factor consists of four levels, namely without N fertilizer, N fertilizer 50% of the standard dose, N fertilizer 100% of the standard dose, and N fertilizer of 150% of the standard dose. Each treatment was tested on 4 oil palm seedlings and repeated 3 times, so that 144 experimental plants were obtained. The observations made were the variable plant performance includes plant height, number of leaves, and stem diameter. Variants of plant nutrient levels included total N nutrient levels, P nutrient levels, and K nutrient levels. The results showed that N-inhibiting microbes contained in organic organic fertilizer increased plant height and stem diameter significantly in oil palm nurseries. The use of a 100% dose of N fertilizer together with organic biofertilizers shows the best crop performance results.

The experiment was carried on a Coto clay (an Oxisol). The effect of four levels of N (0, 57, 170 and 340 kg/ha) and four levels of B (0, 2.3, 4.5, 6.8 kg/ha) were determined using the P.R. 7-65 papaya variety. Treatments were initiated when the transplanted seedlings were three months old, and were repeated every six weeks. The information recorded showed the following results: Increments of N and B levels did not show a marked effect on plant height and stem diameter. Boron tended to be more effective than N in increasing stem height and diameter. The petiole fresh and dry weights increased linearly as the N and B levels were raised. The number and weight of fruits borne on female and hermaphroditic trees increased linearly as the N and 8 levels were raised. The results of the experiment showed that the papaya plant requires a high N and B fertilization rate.

The productivity of forage depends on the availability of nutrients in the soil where it is grown, so fertilization to replace harvested produce is absolutely necessary. This study aims to study the response of gamal and indigofera forage on application of inorganic and organic fertilizers. Research using a completely randomized design factorial pattern of two factors, the first factor is the type of plant (G = Gamal; I = Indigofera) and the second factor is the type of fertilizer (T = without Fertilizer; A = Inorganic fertilizer NPK; K = commercial organic fertilizer; O = conventional organic fertilizer; B = bioorganic fertilizer), repeated 4 times so that it consists of 40 experimental units. The variables observed were plant height, number of leaves, stem diameter, leaf dry weight, stem dry weight, total dry weight of leaves, ratio of dry weight of leaves/stems and leaf area per pot. The results showed that there was no interaction between plant species and types of fertilizer in influencing the response of gamal and indigofera plants. Plant species have a significant effect on stem diameter, while fertilizer types have a significant effect on plant height, leaf dry weight, total dry weight of leaves and leaf area per pot. Based on the results of the study it can be concluded that the response of gamal plants is similar to indigofera, all types of fertilizers can improve the response of plants and organic fertilizers produce the same crop response with inorganic fertilizers. Keywords: gamal, indigofera, inorganic fertilizer, organic fertilizer

Total-N and NO3-N content of forage were determined for six grass species — timothy (Phleum pratense L.); crested wheatgrass (Agropyron cristatum (L.) Gaertn.); intermediate wheatgrass (Agropyron intermedium (Host) Beauv.); stream-bank wheatgrass (Agropyron riparium Scribn. and Smith); bromegrass (Bromus inermis Leyss.); and Russian wild ryegrass (Elymus junceus Fisch.). The grasses were fertilized with ammonium nitrate in early spring and were sampled at four levels of applied N — 0, 185, 550, and 940 kg/ha — and at three stages of maturity — early heading, anthesis, and seed-set. Total-N and NO3-N increased in all grasses with increasing levels of N fertilizer; Russian wild ryegrass showed the greatest increase and timothy the least. As maturity advanced, total-N content decreased. Total-N contents were similar in crested wheatgrass, intermediate wheatgrass, and streambank wheatgrass. As maturity advanced, the NO3-N content of fertilized timothy, crested wheatgrass, and bromegrass decreased while that of Russian wild ryegrass increased. The NO3-N content of intermediate wheatgrass and of stream-bank wheatgrass was highest at anthesis. At 0 and 185 kg N/ha, the NO3-N content was well below the lethal level for ruminants, but at the two higher N fertilizer levels it often exceeded the lethal level. Timothy can be considered a low, Russian wild ryegrass a very high, and the other four grasses high, NO3-N accumulators.
