This research was conducted at Wanasaba Kidul, Talun Sub-District, Cirebon Regency, West Java, Indonesia from June until September 2018. This research is located at altitude of 20 meters above sea levels (masl) and rainfall type method is rainfall type C (rather wet). This research was arranged by Completely Randomized Block Design Factorial, with two factors and repeated three times. First factor is phosphate fertilizers rate with three levels (50, 100, 150 kg ha-1) per plots. Second factor is mycorrhizal arbuscular fungi inoculation rate with three levels (200, 400, 600 kg ha-1). The result showed that phosphate fertilizers gave significantly effect to flowering age, weight of dry pods per plant and weight of dry seeds per plant. Mycorrhizal arbuscular fungi inoculation gave significantly effect number of trifoliate leaves at 28 Days After Planted (DAP). There were interaction between phosphate fertilizers and mycorrhizal arbuscular fungi inoculation to plant height 21 DPA and 28 DPA, root volume and weight of dry seeds per plot.

Blast disease caused by Pyricularia oryzae is one of the primary diseases that can reduce rice production in Indonesia. This disease has spread in almost all agroecosystems, including swamps. This study aimed to obtain information on the incidence and severity of blast disease based on routine monitoring for rice blast disease control strategies in swamp agroecosystems in Central Kalimantan. The blast disease incidence and severity were observed from the early vegetative phase, flowering, and grain ripening until before harvest. Observations were made at the sample point of the same rice clump with an area of 14 ha at the display location of rice varieties and 66 ha at the rice demfarm. The blast incidence in the presence or absence of blast symptoms in the observed clump, while the severity of disease in the form of severe and low damage to the clump was observed using a scoring method that refers to the Standard Evaluation System for Rice from IRRI. Incidence and severity of blast disease at the varieties display and rice demfarm location in Blanti Siam village, Pandih Batu Sub-District, Pulang Pisau District Central Kalimantan was relatively low. In September, blast disease incidence and severity were still low when rice plants were in the vegetative phase. Blast disease incidence and severity increase in October when the plant enters the generative phase. The incidence of the disease decreased in November. Leaves showing blast symptoms ran into leaf death, and blast pathogens did not infect new leaves, so rice blast symptoms were not found or in low conditions.

Planting rice resistant varieties to bacterial leaf blight (BLB) is a major component in controlling BLB disease, which is practical for farmers to implement. However, resistant varieties are constrained by the ability of pathogens that cause BLB disease to form new pathotypes of Xanthomonas oryzae pv. oryzae (Xoo) can break the resistance of rice varieties. This study aimed to evaluate the resistance level of IRBB rice lines to BLB in the field as parent material for crossbreeding resistant varieties to control BLB disease. The research was conducted in Cikadu village, Cibatu sub-district, Purwakarta district, and in Rancamahi village, Purwadadi sub-district, Subang district in the 2018 planting season. The results showed that two IRBB lines, namely IRBB 54 and IRBB 64, the Java 14 differential variety, and the new high yielding variety Inpari 32, consistently reacted highly resistant to BLB in Purwakarta. Three IRBB lines, namely IRBB 2, IRBB 54, IRBB 64, Java 14, and Inpari 32, consistently reacted high resistant to BLB in Subang. In Purwakarta, two types of Xoo were identified: pathotypes IV and VIII. While in Subang, one kind of Xoo was identified, namely pathotype VIII. The highly resistant and resistant varieties can be recommended as parent sources of resistant genes for the assembly of BLB resistant varieties, especially for the Xoo population of pathotypes IV and VIII in Purwakarta and Xoo pathotype VIII in Subang.

The experiment was carried out in Mekarjaya Gantar Village, Indramayu - West Java, in July - November 2021. The experimental method was Randomized Block Design (RAK) with a combination pattern, with two treatments repeated three times, namely the combination treatment of phosphate fertilizer application (100 kg/ha, 150 kg/ha, 200 kg/ha) with spacing treatments (25 cm x 50 cm, 25 cm x 60 cm, and 25 cm x 70 cm). The experimental data were processed using linear model statistical tests, analysis of variance, and Scott-knot cluster further test analysis. The correlation between treatment with growth components and sesame yield was used Product Moment correlation coefficient. The experimental results showed: (1) The combined treatment of distance and phosphate showed plant height at 14 HST, leaf number at 14 HST, and seed weight per clump, but did not affect plant height at 28 HST and 42 HST, leaf number at 28 HST. and 42 HST, stem diameter, root compaction, leaf area index, plant growth rate, fruit number per clump, fruit number per plot, fruit weight per cluster, fruit weight per plot, 1000 seeds, and seed weight per plot ( 2) The highest seed weight of each plot was produced by a combination of treatments F, which was 25 x 60 cm and phosphate 200kg/ha with an average weight of 1.03 kg (together with 1,715 tan/ha), (3) There was a significant correlation between plant height and leaf number at 28 HST and 42 HST with seed weight of each plot in the strong category. However, there was no significant correlation between plant height and leaf number at 14 HST with seed weight in each plot with weak and simple categories.
