Abstract

Biofertilizers are a promising alternative solution to reduce the long-term adverse effects of chemical fertilizers and are increasingly important for promoting sustainable agriculture. Unfortunately, biofertilizers have a relatively short shelf life, and microbial effectiveness often decreases during storage and application. Therefore, innovation is needed regarding the formulation of biological fertilizer carriers that have the potential to maintain microbial viability and effectivity during storage. The comprehensive study was carried out using Systematic Literature Review (SLR) method by the search engine to evaluate and assess the current status of solid carrier formulation to improve the viability and effectiveness of biofertilizers inoculants. The results of a systematic review of scientific literature were obtained from as many as 149 articles from ScienceDirect and Scopus, and a total of 10 articles were chosen for further review. Several carrier materials have been reported can increase the viability and effectiveness of N-fixing inoculant. Each carrier material provides various benefits, such as increased microbial shelf life, microbial activity, and plant growth. Some carrier materials have the potential for further development in Indonesia.

Abstract

This research was conducted from May to September 2022 in the experimental field of the Faculty of Agriculture, Padjadjaran University, Jatinangor District, Sumedang Regency, at an altitude of 700 meters above sea level. This study aims to study the interaction between the application of nutrient solution to the leaves and the type of fertilizer on the growth and yield of large red chili (Capsicum annum L.) Baja F1 variety. The Environmental Design used a Split plot design consisting of two treatments which were repeated 4 times. The main plot was application of nutrient solution to leaves (F) which consisted of two levels: f0 (without application) and f1 (application of nutrient solution to leaves every 10 days). Subplots were the fertilization technology (M) which consisted of four levels: m0 (nutrient solution), m1 (4 tons ha-1 cow compost), m2 (6 kg ha-1 bioamelioran) and m3 (4 tons ha-1 amelioran plus) ). The experimental results showed an interaction between the application of nutrient solution to leaves and the type of fertilizer on growth (plant height 1, 2, 3, 4, 5 WAP, number of leaves 1, 2, 3, 4, 5 WAP, stem diameter 1, 2, 3, 4, 5 WAP) and yield (number of fruits per plant and weight per fruit) of chili plants. Application of nutrient solution to leaves and bioamelioran showed the best results on growth (plant height at 2, 3, 4, and 5 WAP, number of leaves at 1, 2, 3 and 4 WAP, stem diameter 4 and 5 WAP) and yield of chili plants ( number of fruits per plant). The type of amelioran plus fertilizer without the application of nutrient solution to the leaves gave the best results on the growth of chili plants (plant height at 1 WAP, number of leaves at 5 WAP, and stem diameters of 1, 2, and 3 WAP). Types of bioamelioran fertilizers without the application of nutrient solution to the leaves give the best results on chili plant yield (weight per fruit). Keywords: Amelioran plus, Application of nutrient solution to leaves, Bioamelioran, Cow compost,  Nutrient solution A and B, red chili.

Abstract

Plant productivity is influenced by soil quality and availability of plant nutrients. Soil conditioner can improve soil quality by enhancing soil properties. Both macro and micronutrients can be fulfilled through application of nutrient solution containing macro and micronutrients and biofertilizer. This experiment was conducted from at experimental field of the Faculty of Agriculture, Universitas Padjadjaran to test the combination of soil conditioner, NPK fertilizer, nutrient solution (NS), and biofertilizer (BF) effects on soil biological and chemical properties and red chili growth. The experiment was designed using a Randomized Block Design with seven treatments and four replications. The treatments consisted of control, combination of NPK and NS with a dose of 0, 6, and 12 kg.ha-1 BF contained Azotobacter sp., Azospirillum sp., and Pseudomonas sp.. The doses used for a single application were 15 gplant-1 NPK and 300 mLplant-1 NS. Manure was applied to the control treatment and soil conditioner to the other treatments as a basic fertilizer at a dosage of 4 ton.ha-1. The results showed that the combination of soil conditioner, NPK fertilizer, nutrient solution, and biofertilizer had significant effects on soil biological properties and red chili growth, but didn’t show significant effect on soil chemical properties. The combination of soil conditioner + NPK + 12 kg.ha-1 BF increased soil fungal population (113,4 x 103 CFU.mL-1) and bacterial population (599,5 x 108 CFU.mL-1). Meanwhile, the combination of soil conditioner + NS + 6 kg.ha-1 BF increased plant height (60,48 cm).

Abstract

The use of Ultisols for plant cultivation has constraints, namely the nature of the soil is acidic and the availability of phosphate for plants is low. The use of Rocks Phosphate (RP) and Phosphate Solubilizing Bacteria (PSB) can be used as an alternative to increasing the availability of phosphate for environmentally friendly plants. PSB has the potential to increase the solubility and availability of phosphate in plants. The increase in the availability of phosphate for plants can be through the enzyme phosphatase and organic acids produced by PSB. This study aims to examine the effect of the type of PSB consortium and the dose of Rocks Phosphate on P uptake and growth of maize in Ultisols from Kentrong. The research was conducted at the Ciparanje Experimental Garden, Faculty of Agriculture, Padjadjaran University, Jatinangor. The design used was a randomized block design with factorial pattern consisting of phosphate solubilizing bacteria (without the PSB consortium, exogenous PSB consortium, indigenous PSB consortium, and mixed consortium) and Rocks Phosphate dosage (100% SP-36, 100% RP, 80% RP, 60% RP) with three replications. The results showed no interaction between the type of PSB consortium and the dose of Rocks Phosphate. The results of the independent effect showed that the treatment of using SP-36 was the best treatment in available P.

Abstract

Ensuring food security by Indonesia's Golden Year in 2045 presents a formidable challenge, with advancements in agricultural technology anticipated to play a crucial role in attaining this goal. Rice is the major food crop in Indonesia, and its consumption is still considerably high, indicating that daily nutrient uptake relies on its grain. However, the current population of Indonesia demanding rice is 31.2 million tons and this number of populations will grow at the rate of 0.41 percent. The rice consumption of the Indonesian people is quite high, namely 114.6 kg per person per year. The rice harvest area in 2023 decreased by 2.45%, from 10.45 million hectares to 10.20 million hectares, resulting in rice production which also decreased from 31.54 million tons to 30.90 million tons. The average conversion of paddy fields to non-harvest areas in Indonesia reached 100,000 hectares per year. Meanwhile, the average ability to print rice fields is only 60,000 hectares a year. This means that there is a difference in the conversion of paddy fields of around 40,000 hectares per year. Therefore, the purpose of this study is to elucidate how agricultural technology can enhance rice production across different land types in Indonesia, thus supporting food security efforts. To achieve the objectives of this research, a systematic literature review method was used. The result of this study shows that the amalgamation of diverse technological advancements and innovative practices in rice cultivation holds immense promise in bolstering productivity, bolstering sustainability, and tackling nutritional deficiencies. Prospectively, the use of cutting-edge technology offers some insights that can be input for policy formulation, technological innovation, and community engagement strategies aimed at creating a safer, fairer, and more sustainable food future for Indonesia to achieve food security by 2045.

Abstract

The productivity and quality of red chili are greatly influenced by soil conditions and the availability of nutrients. Nutrients play a critical role in the growth and development of red chili plants. This experiment aimed to determine the combination of ameliorant, nutrient solution, and biofertilizer on the population of phosphate-solubilizing bacteria (PSB), available P, P-uptake, and red chili production in Inceptisols. The experiment was conducted at the experimental field of the Faculty of Agriculture, Universitas Padjadjaran. The experiment used a Randomized Complete Block Design (RCBD) with seven treatments and four replications, consisting of control, NPK, and nutrient solution (NS) with doses of 0, 6, and 12 kg ha-1 biofertilizers. The dosage used in a single application was 15 g plant-1 of NPK fertilizer and 300 mL plant-1 of nutrient solution. The base fertilizer consisted of manure in the control treatment and an ameliorant in other treatments at a dose of 4 t ha-1. The results showed that the combination of ameliorant + NPK + 6 kg ha-1 biofertilizer increased PSB population (4.93 x 106 CFU mL-1), available P (15.4 ppm), and P-uptake (0.74 g plant-1). Meanwhile, the combination of ameliorant + nutrient solution + 6 kg ha-1 biofertilizer increased fruit diameter (15 mm), and length of red chili (17.3 cm). Correlation analysis indicated positive correlation between red chili production with stem diameter and fruit length, but a negative correlation with P-uptake. Regression analysis indicated that stem diameter and PSB population had the most dominant effect on red chili yield.

Abstract

Soil fertility is recognized as a crucial factor in supporting plant growth and productivity. The utilization of biofertilizers as environmentally friendly fertilizers is aimed at enhancing soil fertility and plant productivity. This study aims to explore the potential of local material for developing local wisdom biofertilizers (LWB) for achieving sustainable agriculture. A systematic literature review was conducted using bibliometric analysis, Preferred Reporting Items for Systematic Reviews, and Meta-Analyses (PRISMA) method, employing the Scopus search engine with the keywords "local AND wisdom AND biofertilizer" OR "biofertilizer" OR "local AND microorganism" OR "soil AND health OR crop AND productivity OR sustainable agriculture". The search yielded 704 articles, of which 11 were deemed eligible after selection. Based on the literature review, it was found that there are local materials, including fish waste, seaweed, Azolla, fruit waste, Moringa oleifera, microalga, bamboo roots, banana hump, golden snail, mangrove leaves, fruit, and vegetable waste that can be used as raw materials for LWB to improve soil health, plant growth, and productivity. The development of LWB as a new fertilizer technology faces challenges such as lack of regulations, low public trust, limited farmer awareness, weak promotion, and raw material shortages. Further research is needed to intensively study and enhance the effectiveness of LWB through enrichment using beneficial microorganisms.
