Semanggi (Marsilea crenata Presl.) is one of the aquatic plants that have been widely used by the community as food and medicinal raw materials. One of the important factors in cultivating clover is optimal fertilizer management. The incorporation of organic and inorganic nutrients has an effect on soil fertility has been repeatedly demonstrated in several studies, but there are not specific guidelines on clover cultivation. The challenge now is to combine organic matter of different qualities with inorganic fertilizers to optimize nutrient availability for the clover plant. The results of research on clover cultivation have also not been widely carried out. Therefore, it is very important to do this research with the aim of knowing the optimal effect of organic (cow manure) and inorganic (nitrogen, potassium) fertilizers on the growth and yield of clover (Marsilea crenata Presl.). The research was conducted at the Screen House of the Faculty of Agriculture, Brawijaya University. The study was designed using a non-factorial randomized block design (RBD) with 8 (eight) treatment combinations of soil types and fertilization [inorganic (N, K) cow manure organic fertilizer (CM)], namely: P0 = soil, without fertilizer; P1 = soil, 138 kg N ha-1; P2 = soil, 136 kg K ha-1; P3 = soil, N and K, 138 and 136 kg ha-1; P4 = soil, 20x103kg of cow manure ha-1; P5 = soil, 20x103 kg of cow manure ha-1, 138 kg N ha-1; P6 = soil, 20x103 kg of cow manure ha-1, 136 kg K ha-1; P7 = soil, 20x103 kg of cow manure ha-1, N and K, 138 and 136 kg ha-1 with 3 replications, so that 24 experimental units were obtained. Each experimental unit consisted of 5 plants. Growth observations were observed destructively at the ages of 4, 8, 12, 16, 20, 24, 28, 32 days after planting (DAP). The results showed that there was an increase in the growth and yield of biomass in the soil combination, 20x103 kg of cow manure ha-1 (P4) was compared with the treatment without the addition of organic fertilizers (cow manure) on plant growth and yield parameters, such as stolon length (74.78 cm), number of leaves (160.44), leaf area (1379.28 cm2), root length (23.85 cm), stomata density and number of stomata (13.25); Stomata width (10.87 cm); Stomata length (19.76 cm), leaf fresh weight (12,907 g), leaf dry weight (1,802 g), total fresh weight 210,830 g, total dry weight 7,823 g, leaf harvest fresh weight (64.19 g); stalk (130.54 g); root (79.75 g); total 274.48 g), harvest dry weight of leaves (11.36 g); stalk (24.88 g); root (9.55 g); a total of 45.78 g) and the chlorophyll a content (0.804 mg.g-1); chlorophyll b (1.121mg.g-1); and total chlorophyll (1.924 mg.g-1).

<p>ABSTRACT</p><p>Degradation of soil fertility due to inaccurate  application of fertilizer become one of the factors causing the stagnant rice productivity improvement in Indonesia. Straw incorporation, organic fertilizers and biofertilizers applications potentially reduces a rates of inorganic fertilizers and improves soil fertility. The aim of this study was to evaluate growth and yield of 3 lowland rice varieties (high yielding variety, new plant type, and local variety) in response to reduce NPK rates with straw incorporation, organic fertilizer, and biofertilizer in 7th planting season. The research was conducted at rice field in Karawang, West Java, from April-August 2013. The research was arranged in split plot randomized block design with 3 replications. The main plot was fertilizer application consisted of 10 treatments (combination of organic and inorganic fertilizers), while the sub plot was rice varieties (Ciherang, IPB 3S, and Mentik Wangi). The application of inorganic fertilizer, 400 kg NPK 30-6-8 ha-1, was control treatment. Plot size was 6.5 m x 10 m, with a double row spacing (25 cm x 15 cm x 50 cm). The result showed that growth of the three varieties was not significantly different so as the yield at 50% reduced NPK rate with incorporation of straw, organic fertilizer and biofertilizer. Adding of solid and liquid organic fertilizer, and biofertilizers on treatment of straw incorporation + 50% NPK rate was unnecessary due to insignificant yield increase.</p><p>Keywords: Ciherang, fertilizer, IPB 3S, local variety, Mentik Wangi, new plant type</p>

Red onion production can be increased by fertilization. Fertilization serves to provide nutrients for plant growth. Chemical fertilizer provides a bad impact on the environment in the long term so that the application of organic fertilizer can be a recommendation. Organic fertilizers are fertilizers derived from animal matter, animal manure, human excreta, and vegetable matter (e.g. compost and crop residues). Waste mushroom logs, cow manure fertilizer, and decomposers used in this research. All of the matter in this research can be a source of nutrients for growing plants and an increase of production and yield of red onions. The objective of this research was to study the combination test between of waste mushroom logs, cow manure fertilizer, and decomposers to growth and yield of red onion. This research was arranged in a Randomized Block Design (RBD), where the main plot is cow manure fertilizer and waste mushroom log, the subplot in the form of a decomposer. The results showed that there was not interaction between cow manure fertilizer and decomposer waste on all parameters of observed growth and yield of red onion. Special decomposer real treatment of the growth of the number of leaves of plant ages 15 HST (18.98), 20 HST (20.33), 25 HST (23.47), 30 HST (25.76), and 35 HST (26.11), and plant height is 35 HST (33.21 cm). The treatment of waste mushroom logs 100% produces a relatively large number of tubers compared to others, which is 8.89 tubers.

Planting shallots in Buahan Village is only carried out once a year, namely in July. The continuous use of synthetic fertilizers at high doses without being balanced with natural fertilizers has degraded the land so that soil fertility has decreased. The negative impact caused is a decrease in the yield of shallots. Quality organic fertilizers can overcome this problem. Organic vermicompost and biosllury fertilizers are quality organic fertilizers that can replace synthetic fertilizers to increase the growth and yield of shallots. The research objective was to determine the growth and yield of shallots by giving the type and dose of organic fertilizers outside the growing season. The research was conducted from March to July 2019 in Buahan Village, Kintamani District, Bangli Regency. The study used a simple randomized block design with one factor with 6 treatments, namely B0 (Without Organic Fertilizer), B1 (2000 kg / ha vermicompost); B2 (1000 L / ha biosllury) B3 (1000kg / ha vermicompost + 500 L / ha biosllury); B4 (4000 kg / ha vermicompost); B5 (2000 L / ha biosllry); B6 (2000kg / ha vermicompost + 1000 L / ha biosllury); B7 (4000 kg / ha vermicompost + 2000L biosllry) and B8 (5000 kg / ha vermicompost + 3000L / ha biosllury). The parameters observed were plant height, number of tillers, tuber wet weight per clump, harvest dry weight of tubers per clump and number of cloves per clump, soil pH, N-total (%), C-organic and total population of soil microorganisms. The results showed that the type and dose of organic fertilizer had a significant effect on all the meters observed. Treatment of 5000 kg / ha vermicompost + 3000L / ha biosllury gave the highest yield, namely 56.8 g per clump, 60% higher than the control 35.5 g per clump.

To produce optimally good quality shallots, proper cultivation techniques are required. Efforts that can be made include modifying the environment in which plants grow. Alternative efforts to increase the quantity and quality of agricultural products, especially shallots can be done by using organic fertilizers and the use of Trichoderma sp. as a plant growth promoting agent, as well as improving the quality of organic fertilizers. The purpose of this study was to determine the role of Trichoderma in increasing the ability of plants to absorb nutrients from the growing media and to determine the best type of organic fertilizer to increase the growth and yield of shallots. The research was conducted at the experimental field of the Faculty of Agriculture, UPN "Veteran" Yogyakarta, Wedomartani, Sleman, Yogyakarta Special Region, at an altitude of approximately 104 meters above sea level. The time of the research is from May to July 2021. This study was arranged in a factorial Completely Randomized Block Design with 3 replications. The first factor is the type of manure (P1: without manure, P2: cow manure and P3: goat manure). The second factor was inoculation of Trichoderma sp isolates (I0: without inoculation of Trichoderma sp. isolates. and I1: by inoculation of Trichoderma sp. isolates). Based on the results of this study, it can be concluded that the addition of cow and goat manure was able to produce more leaves and plant height than without the addition of manure, although it did not show a significant effect on the yield of shallot bulbs. There is no significant difference between cow manure and goat manure. Trichoderma inoculation has not had a significant effect on the growth and yield of shallots
