Expanding rice planting areas is one of Government’s strategy that could overcome increasing rice demand nationally. However the more rice planting areas the more chemical fertilizer used, which has a deleterious side effect on the soil, environment and high in cost production. Therefore, it is necessary to develop a less or without chemical fertilizer rice production system through applying biofertilizer and combining with a proper cultivation technology such as management on plant spacing. An experiment was conducted at Pusakanagara Research Station, Indonesia during August to December 2018 to evaluate the effect of form and dosage of biofertilizer application at different plant spacing toward the growth and yield response of lowland rice. The experiment was arranged in split-split-plot design with three replications. The main plot was plant spacing, i.e T1 – Jajar Legowo pattern 2:1 (25 cm - 50 cm) x 12,5 cm and T2 – Jajar Legowo Pattern 4:1 (25 cm - 50 cm) x 12,5 cm. The sub-plot was form of biofertilizer, i.e W1 – powder and W2 – granule, while the sub-sub-plot was dosage of biofertilizer, i.e P0 – without biofertilizer (control), P1 – 150 g/ha, P2 – 250 g/ha, and P3 – 300 g/ha. The result showed The interaction between plant spacing (T) x form of biofertilizer (W) x dosage of biofertilizer (P) affected significant on tiller number and panicle length and not significantly at the yield and yield components of lowland rice soil. The highest yield at control with the powder form at Jajar Legowo pattern 2:1 was 8.7 t/ha miled dry grain, but not significantly different from other biofertilizer dosage level. Applying biofertilizer at a rate of 150 g/ha in the form of powder at Jajar Legowo pattern 2:1 could increase grain yield up to 2.5 t/ha more than Jajar Legowo pattern 4:1.

“…In particular, the NO 3 --N content in soil treated with J0 increased by nearly 25% compared to CK, indicating that S. cerevisiae can accelerate the mineralization of soil nitrogen. The high levels of available nitrogen (AN) are the reason why yeast is able to increase the chlorophyll content of leaves [76] . Rice is widely considered to be sensitive to soil salinity [42,77] , and the results of this study demonstrate that the use of microbial agents is a feasible strategy to reduce soil salt stress.…”

In order to save fresh water and reduce soil salt accumulation, reclaimed water-fresh water combined irrigation, i.e, irrigation with reclaimed water for 50 d and then with fresh water till harvest, was used in rice planting. Bacillus subtilis and Saccharomyces cerevisiae were inoculated into the soil at the end of reclaimed water irrigation. The inoculation weight per pot of these microorganisms was as follows: 0 g and 0 g (J0), 5 g and 0 g (J1), 3.75 g and 1.25 g (J2), 2.5 g and 2.5 g (J3), 1.25 g and 3.75 g (J4), and 0 g and 5 g (J5), respectively. Treatment using reclaimed water in the whole stage was used as the control (CK). The plant height, tiller, physical and chemical properties of the soil, and soil bacterial diversity were measured. It was found that the plant height of rice was increased significantly by J1-J5 treatments. The dry weight of rice root, stem, and panicle and the 1000-grain weight increased significantly, while the leaf dry weight decreased. Microorganism inoculation significantly increased the nutrient absorption capacity of the crops. J1, J2, and J4 treatments significantly increased the amount of nitrate-nitrogen, ammonium nitrogen, available phosphorus, and available potassium, while J3, J4, and J5 treatments increased the soil organic matter, and microbial inoculation significantly decreased the EC of soil. J4 treatment induced the largest reduction in EC, and microorganisms treatments increased soil pH. Bacterial function prediction based on the KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway indicated that soil metabolic function was not significantly disturbed by the treatments. Organic matter and pH are the two main factors affecting the structure of the bacterial community in soil. 3.75 g of B. subtilis and 1.25 g of S. cerevisiae per pot is the best inoculation ratio.

“…In addition, the direct seed planting system generated good results at the flowering age with a time difference of 3-10 days. The direct seed planting system can accelerate the flowering age by nine days compared to conventional planting patterns and harvesting age (Bahua & Gubali, 2020;Sahardi, Nappu, Idaryani, Nurlaila, & Syam, 2021). The direct seed planting system showed better prospects and can increase the production of harvested dry grain, eliminate the negative impact of nursery and grain quality, and shorten the life of the plant (Bahua & Gubali, 2020).…”

This research aims to determine the appropriate concentrations of nitrogen, phosphorus, and potassium (NPK) in liquid organic fertilizer (LOF) and to determine the appropriate dose of NPK and LOF concentrations for the growth and yield of rice plants. The research was conducted in Mertajati Village, Sausu Subdistrict, Parigi Moutong Regency, Indonesia, from August to December 2019. The study used a two-factor randomized block design (RBD). The first factor is the dose of NPK, which consists of three levels, i.e., NPK 200 kg/ha-1, NPK 400 kg/ha-1, and NPK 600 kg/ha-1. The second factor is the concentration of LOF, which also consists of three concentration levels, i.e., without LOF, 2.5% LOF, and 5.0% LOF. The results revealed that the effects of LOF addition were the same for each dose of NPK and increasing the dose of NPK required an increase in the concentration of LOF. A dose of 400 kg ha-1 NPK fertilizer resulted in better growth and a higher yield, indicated by taller plants, higher panicles (19.53 panicles), and higher dry grain production (7.69 ton/ha-1). The application of 2.5% liquid organic fertilizer resulted in better growth and a higher yield, indicated by taller plants, a higher number of tillers, faster flowering, more panicles per clump (19.72 panicles/clump-1), a higher number of grains per panicle, a higher pithy grain weight (30.26 grams/1000 grains), and higher yields (7.79 tons/ha-1).
