Abstract

Salinization of soil in coastal area is a serious problem and is increasing steadly. Application biofertilizer consortium is able to improve productivity of rice crops (Oryza sativa L.) grown in saline soils. Biofertilizer supplies nutrients and phytohormones that are beneficial for plant. The aim of this research was to find combination effects of biofertilizer consortium on population of phosphate solubilizing bacteria and dry weight of paddy grown in several level of salinity. This research was conducted from December 2016 to February 2017 at greenhouse of Faculty of Agriculture, Universitas Padjadjaran with altitude 752 meters above sea levels. This research used randomized block design single factor experiment which consist of eight combinations of biofertilizer (Azotobacter sp., Azospirillum sp., endophytic bacteria, PSB, and AMF) and salinity with four replications: A (non saline 0 mmhos cm-1), B (non saline of 0 mmhos cm-1 + biofertilizer), C (salinity of 2 mmhos cm-1), D (salinity of 2 mmhos cm-1+ biofertilizer), E (salinity of 4 mmhos cm-1), F (salinity of 4 mmhos cm-1+ biofertilizer), G (salinity of 6 mmhos cm-1), H (salinity of 6 mmhos cm-1+ biofertilizer). The result showed that at salinity level of 2-4 mmhos cm-1 the crops still survived growing under salinity stress. Salinity treatment of 2 mmhos cm-1 + biofertilizer significantly affected popuation of phosphate solubilizing bacteria and salinity treatment of 4 mmhos cm-1 + biofertilizer significantly affected dry weight of rice.

Abstract

Biofertilizers and Azolla are local potentials sources that can be used for inorganic fertilizers efficiency in increasing crop yields. The purpose of this study was to determine the dose of inorganic fertilizers that can be reduced by the application of biofertilizers and Azolla in lowland rice plants. The aims of study was to determine the increase in N plants, N soil, available P, P uptake, C organic, and the yield of lowland rice. The experiment was carried out at the Experimental Field, Ciparanje, Faculty of Agriculture, Padjadjaran University, in Jatinangor. The treatment in this experiment were A = without the use of fertilizer, B = NPK 100% Fertilizer of recommended dosage, C = 0% NPK + Biofertilizer + Azolla, D = 25% NPK + Biofertilizer + Azolla, E = 50% NPK + Biofertilizer + Azolla, and F = 75% NPK + Biofertilizer + Azolla. The study design used was a Randomized Block Design with four replications. The results showed that biofertilizer and Azolla combined with inorganic fertilizers can enhance total N soil, N plants, P available soil, P uptake of plants, and C organic soil. Application 50% NPK + Azolla + biofertilizer could increased Milled Dry Grain by 10.82% compared to the recommended dosage of inorganic fertilizer (100% NPK) and caould decrease the use of inorganic fertilizer by 50%.

Abstract

Carbofuran insecticide widely used in rice production. The carbofuran residue in agricultural threatens wide life and human health since its active ingredient carbamate is toxic. Humic acid (HA) amendment is an effective way to minimize the residue in soil since HA can adsorb the organic pollutant and induce growth of fungus that degrade the carbofuran. The objective of this research was to observe the influence of HA on the carbofuran residues in soil, straw, and rice; as well as yield of paddy (Oryza sativa L.) grown in carbofuran contaminated potted soil. The level of carbofuran residue in soil before experiment was 10 mg kg-1. The experiment was setup in Randomized Block Design to test various HAs extracted from organic matter. The results indicated that humic acid didn’t affect plant growth and yield but decreased the carbofuran residue in straw and unhusked rice grain. Rhizosphere of rice treated with HA showed higher fungal count than control. This experiment suggests that HA were effectively used to control the carbofuran residue in soil and rice grown in low carbofuran-contamination agricultural soil

Abstract

Utilization of saline land as an effort to increase rice productivity is still constrained by the adverse effects of salinity stress. The solution to this effort can be done by utilizing PGPR biofertilizers and applying ameliorant briquettes. The purpose of this study was to evaluate the effect of using biofertilizers and ameliorant briquettes on saline soils with various levels of salinity on the growth of rice plants. This research was conducted at the Ciparanje Jatinangor screen house from September 2022 to January 2023. The research design used was a randomized block design with 12 treatments and 3 replications. The treatment applied was PGPR biofertilizer, ameliorant briquettes, and their combination on saline soil 4 and 8 dS m-1 compared to control (non-saline soil). The results showed that PGPR biofertilizer increased the height of rice plants on saline soils 4 and 8 dS m-1 7 DAP. At 14 DAP, PGPR biofertilizer, ameliorant briquettes, and their combinations did not increase rice plant height, root length and volume, wet weight, and dry weight of rice plants, although the application of biofertilizers, ameliorant briquettes, and their combinations tended to increase wet weight and dry weight of rice plant compared to soil with the same salinity without biofertilizers and ameliorant briquettes.
