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

The high content of NaCl in soil may lead to nutrient imbalance and inhibit the Nitrogen uptake by plants. Azolla pinnata can be used as an organic ameliorant to help plant roots in absorbing nutrients and enhancing the number of available N for plants. The aims of this research were to ascertain whether Azolla pinnata as organic ameliorant gave the significant difference on the enhancement of N content of soil, pH of soil, and dry weight of rice plant on various salinity level of soil and also to find out if Azolla pinnata can suppress salinity stress at certain salinity. The experiment was conducted at the Greenhouse of Faculty of Agriculture Universitas Padjadjaran, Jatinangor and also at the Laboratory of Soil Fertility and Plant Nutrion, Departement of Soil Science and Land Resources on November 2016 until March 2017. The experimental design used was randomized block design with 8 treatments and 4 replications. The treatments consist of without the organic ameliorant Azolla pinnata, and with the application of Azolla pinnata on salinity level 0, 2, 4, 6 mmhos cm-1. The results showed that the application of NaCl and Azolla pinnata gave the significant difference on soil pH, and dry weight of plant. The application of Azolla pinnata is not able yet to suppress the rice symptom of salinity stress at 2, 4, and 6 mmhos cm-1 on the enhancement of dry weight of plant. The application of Azolla at salinity 6 mmhos cm-1 was equivalent with salinity 2 mmhos cm-1 in producing dry weight of plant.
