“…The phosphorous impact on rice yield was also reported by Dakshina-Murthy et al [34] who observed increasing of rice yield with phosphorous supplying. Phosphorous application induced increasing of rice yield and quality [10]. Then, rice cultivation in Benin need to supply phosphorous because in tropical Africa soil, phosphorous availability of plant was the lowest due to susceptibility losses by leaching, run off (on sandy textured soils) and fixation by soil inorganic colloids [35].…”

“…However, the local rice production doesn't cover the rice needs of the population. In West Africa most rice is grown under rainfed conditions and among the factors which limit the rice yield, plant nutrients are the major constraint in increasing of their production [10]. This is because of the severe nutrient depletion and the widespread decline in the fertility of African soils, leading to abysmally low rainfed rice yields.…”

Inorganic fertilizers are alternative ways of providing the necessary nutrients to rice crop and increase its productivity. In order to identify the factors determining inorganic fertilizer technology adoption and rainfed rice yield, a survey was carried out among 763 farmers in 11 municipalities in four agriculture development centers (ADC) of Benin. Composite soil samples were collected from 227 farmer fields and analyzed at the laboratory. Rainfed rice yields were determined in these different fields. Data collected was analyzed with R version 3.5.1 software. Results show that inorganic fertilizer technology adoption depends significantly on age, educational status, household size, contribution of rice to household income and organic fertilizer use (0.004 < p < 0.034). However, using intensity of inorganic fertilizer is significantly influenced by the age of the farmer, the quality of the training of the farmer on soil fertility management, filed areas under rice crop, contribution of rice to household income, years of farming experience, inorganic fertilizers availability and organic fertilizer use (0.0001 < p < 0.023). Inorganic fertilizer use intensity ranges from 12.6 to 248.9 kg•ha −1 with a mean of 74.68 kg•ha −1. The quantities of inorganic fertilizer applied differ more importantly from one farmer to another and range from 4.58% to 90.5% with a mean of 27.15% of the level recommended by research. However, nitrogen, phosphorous, potassium, organic carbon, pH water, and exchanging capacity cation determine the rainfed rice yield. The policies that aim at promoting inorganic fertilizer among rainfed rice farmers must take into account these factors.

“…Furthermore, sufficient nitrogen rate remarkably increased grain yield and quality [26]. Beside nitrogen, phosphorus has important role as energy storage and transfer within plant [27]. Phosphate has a function in transporting energy from the results of plant metabolism, stimulating root growth, flowering, seed formation and cell division; Potassium has a function in the photosynthesis process, transporting products from assimilation, water, minerals and enzymes, able to increase plant immunity to disease, and Nitrogen has a function in stimulating growth in plants to synthesize amino acids and proteins in plants [19,[28][29][30][31].…”

The progressive decrease in rice production in Indonesia is associated with soil infertility, resulting in inhibited plant growth. This study investigated the impact of bioactivators on soil properties and the growth and yield of two rice (Oryza sativa L.) varieties, namely Inpari 32 and IR 64. A factorial nesting design was implemented, taking into account two primary factors: the dose of bioactivator (ranging from 10-30 ml/l, applied pre-or postplowing) and the rice variety. Two control conditions, namely inorganic and organic fertilizers, were also included. The results demonstrated that both the rice variety and bioactivator application significantly influenced various plant and soil parameters, such as plant height, clump diameter, number of tillers per clump, root length, plant fresh and dry weight, yield, and soil properties. While the control treatments of inorganic and organic fertilizers yielded superior results in terms of clump diameter and number of tillers, bioactivator application resulted in longer roots and higher biomass across both rice varieties. Notably, the application of a 10 ml dose of bioactivator prior to plowing, specifically on the Inpari 32 variety, was found to improve plant dry weight and fresh weight more effectively than the control and other treatments. Moreover, post-plowing application of a 20 ml/l bioactivator concentration increased soil water content, the potential of C-organic, and P2O5. These findings suggest that bioactivator application could be an effective strategy for enhancing soil fertility and rice crop productivity, thereby addressing the ongoing decrease in rice production in Indonesia.

“…Jumlah malai per rumpun (r=-0,0550) tidak memiliki korelasi nyata terhadap hasil. Badawi et al (2017) melaporkan bahwa peningkatan dosis P2O5 meningkatkan jumlah malai. Pemberian pupuk P2O5 tidak berpengaruh nyata dan tidak berkorelasi nyata terhadap hasil pada lahan sawah dengan status P tinggi, menunjukkan tanaman tidak respon terhadap pemupukan P2O5 (Ismon, 2016) Peningkatan dosis K2O hingga 200% dari dosis acuan meningkatkan jumlah gabah per malai sebesar 30,92% dibandingkan perlakuan tanpa K 2 O. Peningkatan dosis K 2 O hingga 150% dari dosis acuan meningkatkan bobot 1.000 butir sebesar 5,04% dibandingkan tanpa penambahan pupuk K (Tabel 3).…”

Fertilizer requirements for each rice variety are different from other varieties. Research on the optimum dosage of fertilization on new superior varieties is needed to obtain optimum growth and yield. This study aims to determine the optimum dosage of N, P, and K fertilizer for the growth and productivity of lowland rice of the Bioemas Agritan variety. The research was conducted at Banten Assessment Institute for Agricultural Technology, from February 2022 to June 2022 on soils with very low C-organic and total N conditions. The study consisted of three parallel experiments, namely the N, and P, K fertilization experiment using a single factor randomized complete block design which was repeated three times. Fertilizer dosages consist of five levels, namely 0, 50, 100, 150, and 200% of the reference dosage. Determination of the optimum dosage based on the maximum value of the relative yield quadratic equation. The optimum fertilizer dosage for the lowland rice variety Bioemas Agritan is 140,93% of the reference dosage or equivalent to 422,79 kg ha-1 urea, while the optimum dosage of P2O5 and K2O fertilizer cannot be determined.ABSTRAK Kebutuhan pupuk setiap varietas padi berbeda antara varietas satu dengan varietas lainnya. Penelitian dosis optimum pemupukan pada varietas unggul baru diperlukan untuk mendapatkan pertumbuhan dan hasil yang optimum. Penelitian ini bertujuan untuk menentukan dosis optimum pupuk N, P, K untuk pertumbuhan dan produktivitas padi sawah varietas Bioemas Agritan. Penelitian dilaksanakan di BPTP Banten, pada bulan Februari 2022 sampai dengan Juni 2022 pada tanah dengan kondisi C-organik dan N total sangat rendah. Penelitian terdiri atas tiga percobaan paralel yaitu percobaan pemupukan N, P, K menggunakan rancangan kelompok lengkap teracak faktor tunggal yang diulang sebanyak tiga kali. Dosis pupuk terdiri atas lima taraf yaitu 0, 50, 100, 150, dan 200 % dari dosis acuan. Penentuan dosis optimum berdasarkan nilai maksimum dari persamaan kuadratik hasil relatif. Dosis pupuk optimum untuk padi sawah varietas Bioemas Agritan adalah 140,93% dari dosis acuan atau setara dengan 422,79 kg ha-1 urea, sedangkan dosis optimum pupuk P2O5 dan K2Otidak dapat ditentukan.
