ABSTRACT<br />Application of organic fertilizer into the soil is designated as a source of macro, micro nutrients and organic acids; it also acts as soil ameliorant that improve physical, chemical and biological properties of soil. Application of high rates organic fertilizer has a constraint namely the availability and ease of application. Therefore, it is necessary to learn the use of organic fertilizer with low rates to improve the efficiency of chemical fertilizers. This research was aimed to study the effect of organic and inorganic fertilizers on growth and yield of paddy rice, as well as the efficiency of N, P, K inorganic fertilizer. Field experiment was conducted at Sawah Baru Research Station, University Farm IPB, Bogor, West Java from September to December 2013. The experiment used Randomized Block Design consisted of two factors: rates of organic fertilizer (0, 250, 500, 750, and 1,000 kg ha-1), and rates of inorganic fertilizer (0, 100, 200, 300, and 400 kg ha-1). The results suggested that the application of 1,000 kg organic fertilizer ha-1 + 400 kg inorganic fertilizer ha-1 did not show significant interaction. Application of organic fertilizer alone up to 1,000 kg ha-1 resulted in low growth and yield. Increasing rates of  application up to 400 kg inorganic fertilizer ha-1 increased the growth and yield of paddy rice. The highest N efficiency was 89.19% at a rate of 500 kg organic fertilizer ha-1 + 200 kg inorganic fertilizer ha-1, whereas the highest efficiency of P and K, respectively were 69.55% and 92.52% at a rate of 750 kg organic fertilizer ha-1 + 300 kg inorganic fertilizer ha-1.<br />Keywords: NPK, organic fertilizer, paddy rice

The experiment was conducted during rabi season 2019-2020 at Agricultural Research Station, On Farm Research Division, Alamnagar, Rangpur to find out the useful effects of organic fertilizer on growth and yield of tomato. The experiment was arranged in a randomized complete block design (RCBD) with five treatments in three (03) compacted replicate blocks. The treatments included T1: 100% Recommended Chemical Fertilizer (RCF), T2: 85% CF + 3 tha-1 organic Fertilizer (OF), T3: 85% CF + 1 tha-1 OF, T4: 70% CF + 3 tha-1 OF and T5: 70% CF + 1 tha-1 OF. The highest yield was observed in T2 (50.59 t ha-1) due to more number of fruit plant-1& weight of fruit plant-1 and the lowest was in T5 (35.32 t ha-1). These results may be due the parameters of growth components increased with increasing amount of organic and inorganic fertilizers applied. Combination of organic and inorganic fertilizer treated plots produced higher yield than plots without combination of organic and inorganic fertilizer. The highest gross return (BDT. 607080) was found in T2 treatment and the lowest gross return (BDT. 423840) was recorded from T5. The highest gross margin (BDT. 328520 ha-1) was obtained from T2. The lowest gross margin (Tk. 145280 ha-1) was obtained from T5. Integrated nutrient management (combination of organic and inorganic fertilizer) is the best option for higher tomato production in Bangladesh. Progressive Agriculture 32 (1): 10-16, 2021

Shallot is the most produced vegetable in Indonesia. The consumption of shallot per kg/capita/year is continuously increasing, therefore there is a need to ensure enough supply. The lack of nutrients in the soil is a problem in shallot production. Shallot needs macronutrients such as Nitrogen (N), Phosphorus (P), Potassium (K), and Calcium (Ca) to improve its yield and quality. The application of liquid organic fertilizer from coconut husk and dolomite can be the solution. This study was conducted using Factorial Randomized Block Design consisting of two factors, concentration of liquid organic fertilizer (0%, 10%, 20%, and 30%) and dolomite (with dolomite or without). The results showed that the application of 20% liquid organic fertilizer, the application of dolomite, and the combination of both (P2D1) had the highest value on fresh shallot bulbs weight per clumps and bulb weight after storage parameters, and had the lowest value on weight loss percentage parameter.

       Rice is a food that produces rice. This food is a staple food for most Indonesians. Even as a staple food, rice can be replaced or substituted by other food ingredients, but rice has its own value for people who are accustomed to eating rice and cannot be easily replaced by other food ingredients. This study aims (i) to know the effect, and (ii) to get the best dose of granule organic fertilizer on the growth and yield of rice plants of Ciherang Varieties on lebak lowland. This research was conducted in Harusan Village, Amuntai Tengah District, North Hulu Regency, from February to May 2011. This study used a single randomized block design (RBD). The factors studied were 5 levels of granule organic fertilizer, namely: g0: 0 ton.ha-1, g1: 1 ton.ha-1 equivalent to or 8.571 g per clump or 0.3 kg per plot. g2: 2 ton.ha-1 is equivalent to 17.142 g per clump, or 0.6 kg per plot. g3: 3 ton.ha-1 is equivalent to 25,714 g per clump, or 0.9 kg per plot. g4: 4 ton.ha-1 is equivalent to 34.285 g per clump, or 1.2 kg per plot. The factors studied were as much as granule organic fertilizer. The results showed that the treatment of granular organic fertilizer dosage did not affect plant height, many tillers, but the treatment had a significant effect on the number of filled grain per clump. The treatment of granulated organic fertilizer dosage of 2 tons.ha-1 is equivalent to 17.142 g per clump, which is the best dose of the number of filled grain per clump

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.
