Fertilizer Use

Granular organic fertilizers have been increasingly used in agriculture due to the longer delivery of nutrients to plants and the milder impact on the environment. The aim of this study was to determine the energy, environmental and economic efficiency of granular and non-granular organic fertilizers. Four technological scenarios of organic fertilizer use were used for comparative assessment: (1) manure fertilization (16.0 t ha−1), (2) manure fertilization (30.0 t ha−1), (3) manure pellet fertilization (2.0 t ha−1), and (4) fertilization with meat and bone meal pellets (0.7 t ha−1). Experimental studies using the mass flow method of laser spectroscopy were performed to evaluate the comparative environmental impact of granular and non-granular organic fertilizers. Economic assessment was performed for mechanized technological operations of loading, transportation and distribution of organic fertilizers, estimating the price of aggregates used and fuel consumed, the costs of individual technological operations and other indirect costs. The results showed that for mechanized technological operations, when fertilizing with granular organic manure and meat and bone meal fertilizer, energy consumption is 3.2 to 4.0 times lower compared to fertilization with manure. The average ammonia (NH3) emissions from granular organic fertilizers were found to be six times lower than from non-granular organic fertilizers. The lowest costs for mechanized works were incurred when using meat and bone meal pellets, the highest economic benefits of organic fertilizers by elements was when using manure 30 t ha−1, and the highest costs for organic fertilizers were incurred when using manure pellets.

[CABBAGE (Brassica olacea var. capitata) GROWTH AND YIELD AFFECTED BY COMBINATION OF ORGANIC AND INORGANIC FERTILIZER APPLICATIONS]. The use of organic fertilizer increasingly sought by farmers due to the increase in demand for organic products by consumers and also awareness of the sustainability of the land. The use of organic fertilizers in the cultivation alone could improve the soil quality but needs to be balanced with inorganic fertilizers to meet the nutrient adequacy. This study aims to examine the effect of organic and inorganic fertilizers combination on the growth and cabbage yield, and also to determine the most efficient dosage combination of organic and inorganic fertilizers. This research was conducted at the IPB Pasir Sarongge Experimental Station, Cianjur, West Java from November 2020 to February 2021. The study was compiled using RCBD with 4 replications and 7 treatments. The results showed the combination of 0.75 doses of inorganic fertilizer (150 kg/ha of urea, 75 kg/ha SP36, and 75 kg/ha KCl) and 3 tons/ha of organic fertilizer could increase 14.87 to 15.44% plant height and the number of leaves at 12.82 -15.11% compared to the same dose of inorganic fertilizer treatment alone. The combination of 1 dose (200 kg/ha of urea, 100 kg/ha SP36, and 100 kg/ha KCl) inorganic fertilizer application and 2 tonnes/ha of organic fertilizer could increase 50,60% yield/plot and yield/ha cabbage than 1 dose of inorganic fertilizer treatment..

The effect of application of sole organic, inorganic fertilizers and their combinations was investigated on the growth and biological yield of Fluted pumpkin (Telfairia occidentalis) at the Teaching and Research Farm, Babcock University, Ilishan Remo, Ogun state, Nigeria. Ten treatments were involved namely: No fertilizer (control), 100kgN/ha as Sulphate of Ammonia, SA (21%N), 100kgN/ha as Composted Maize Cob, CMC (0.97%N), 100kgN/ha as Composted Saw Dust, CSD (1.01%N), 50:50 CMC/SA combination, 50:50 CSD/SA combination, 50:50 CMC/CSD combination, 75:25 CMC/SA combination, 75:25 CSD/SA combination, 75:25 CMC/CSD combination, the treatments were replicated four times using Randomized Complete Block Design (RCBD). Seedling emergence, Leaf area, Leaf number, Plant height and dry matter weight of the crops were assessed. On the Plant height and Leaf number, application of 75:25 CMC/SA combination resulted in taller plants and more leafiness at 3 WAP compared to 75:25 CMC/CSD combination. The application of 100kgN/ha as sole Sulphate of Ammonia, gave the least leaf number and the shortest plant at 4WAP. The sole application of any of the organic fertilizers 100kgN/ha has proven to be superior in terms of (vegetative yield) of Telfairia occidentalis (ugu-elu) than its combination of each of the organic fertilizer with sulphate of ammonia.Keywords: Organic fertilizer, Inorganic fertilizer, Fluted pumpkin, Yield.

<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>

Oil palm (Elaeis guineensis Jacq.) holds a very strategic role in the Indonesia economy. Plants that have reached the economical age of 25 years need to be replanted using qualified oil palm seedling. The qualified seedling is obtained through proper fertilization. The combination of NPK fertilizer and organic material of oil palm empty fruit bunches (OPEFB) which has been given a cellulolytic bacterial consortium can provide sufficient nutrients for the growth of oil palm seedlings. The study aimed to determine the effect of giving a combination of OPEFB organic material, cellulolytic bacterial consortium, and NPK fertilizer on the growth of oil palm seedling (Elaeis guineensis Jacq.) at main nursery. This experiment used a single factor experiment arranged in a Completely Randomized Design (CRD). The treatments were a 100% NPK, a OPEFB compost, a 50% NPK + OPEFB compost, a 50% NPK + OPEFB + Cellulolytic bacterial consortium, and a OPEFB + cellulolytic bacterial consortium. The results showed that the application of inorganic fertilizers combined with organic fertilizers (a OPEFB compost and a OPEFB + cellulolytic bacterial consortium) had a good effect on each parameter. Giving organic fertilizer without inorganic fertilizer had not affected plant growth on all parameters. Application of a OPEFB compost and a OPEFB + cellulolytic bacterial consortium can reduce the use of inorganic fertilizers by 50%.

Phosphorus Losses

Phosphorus (P) is one of the limiting factors of eutrophication. P added to soil from fertilizer application could pose a threat to water quality. According to agricultural habits, swine manure (SM), oil cake (OC), biogas slurry (BS), commercial organic fertilizer (OF) and compound fertilizer (CF) were selected to compare their P losses on a slope-land under natural rainfall. The results showed that P losses of above fertilizers had significant differences (P &lt; 0.05) compared with control. P losses order arranged by Duncan test showed as total P (TP): SM &gt; OF &gt; OC &gt; CF &gt; BS &gt; CK, total dissolved P (TDP): SM &gt; OF &gt; BS &gt; CF &gt; OC &gt; CK, and particulate P (PP): OC &gt; SM &gt; OF &gt; CF &gt; BS &gt; CK. Concentrations of all the phosphorus forms increased with the increased rainfall. The ratio of TDP to TP gradually decreased after fertilizer application, and PP gradually increased. PP was the dominant form in surface runoff. Organic fertilizers had more P losses than inorganic fertilizers, even though both of them had obvious P losses.

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).
