The purpose of this study was to determine the effect of land preparation methods on the soil infiltration which can be used as a basis for designing irrigation for dryland rice cultivation. The study was arranged in a completely randomized design (CRD) with three land preparation treatments, namely T0 (no tillage), T1 (hoeing), and T2 (hoeing plus loosening). Each treatment was carried out with three replication plots. Artificial rain was given with an average intensity of 4.61 mm/h for 120 min. Observations were made on the infiltration thickness and rainwater volume. Results showed that land preparation methods resulted in very significant differences in the cumulative infiltration depth and infiltration rate, where the T2 treatment caused the highest infiltration. During 120 minutes of rain, 331.83 liters of water volume was poured out and resulted in an average infiltration thickness of 7.3 cm for T0 (no tillage), 18.09 cm for T1 (hoeing), and 21,3 cm for T2 (hoeing plus loosening). The results also showed that cumulative infiltration (y) increased with rain water volume (x) that followd a logarithmic curve with an R2 value of more 94-98% for the three land preparation methods with order T2 > T1 > T0.Keywords: Rain, Tillage, Infiltration, Dry land, Rice
This study aims to determine the effect of the volume of water application and the composition of goat manure and urea on the growth and yield of sunggal rice varieties. This research was conducted in Kepuhan Hamlet, Argorejo Village, Sedayu District, Bantul Regency, DIY from September to December 2021. The experimental design in this study was a Completely Randomized Design (CRD) with 3 replications. There are two factors consisting of the volume of water supply, namely: N1 (300 ml), N2 (600 ml), N3 (900) and the composition factor of goat manure: urea, namely: P1 {80% (31.4 g):20 % (7.85 g)}, P2 {50% (19.625 g):50% (19.625 g)} and P3 {20% (7.85 g):80%(31.4 g)}. There were two variables observed, namely growth variables including plant height, number of tillers, fresh weight of stover, and dry weight of stover and yield variables including number of panicles, panicle length, percentage of grain content, weight per 1000 grains, weight of grain per clump and weight of grain. contents per clump. Observational analysis used variance at a level of 5%, followed by Duncan's Multiple Range Test (DMRT) at a level of = 5%. The results showed that the volume of water treatment and the composition of goat manure showed no interaction with all growth variables, but there was a significant difference in the fresh weight of the stover. Meanwhile, for the treatment variable, the volume of N1 water as much as 300 ml and the composition of goat manure and urea P2 50%:50% showed an interaction with the yield variable, namely weight of grain per clump and weight of filled grain per clump.
This study aims to determine the concentration of liquid smoke on the growth and yield of white and red radishes. Knowing the best type of soil by giving the concentration of liquid smoke for the growth and yield of red and white radishes. Knowing the type of radish that gives the best radish growth and yield. The research was carried out at the UPTD Bantul Agricultural Seed Center on Mindi Street, Ngentak Hamlet, Sumberagung Village, Kapanewon Jetis, Bantul Regency, Special Region of Yogyakarta starting in October 2022 - January 2023. This research was a factorial experiment consisting of 3 factors. The first factor is the type of soil, the concentration of liquid smoke, and the type of horseradish. Based on the results of the study, it can be concluded that the Mediterranean soil type treatment gave better results than the red-yellow podzolic soil. Treatment of liquid smoke concentration of 1% and 3% gave the same results. This type of white radish plant gives better growth and yield than the red radish type
