Abstract

This study aimed to determine the effects of PGPR type and application interval on the growth and yield of cucumber plants. The study was conducted from October 26 to December 15, 2025, in Menjing Village, Jenawi Subdistrict, Karanganyar Regency, on Latosol soil at an elevation of 510 meters above sea level. This study employed a factorial design with a Randomized Complete Block Design (RCBD), consisting of two treatment factors and three replications. The first treatment factor was the type of PGPR (M), comprising three types (M1 = bamboo roots, M2 = mimosa pudica roots, and M3 = a mixture of bamboo and mimosa pudica roots). The second treatment factor, the PGPR application interval (P), consisted of three levels (I1 = 4 days, I2 = 8 days, and I3 = 12 days). The interaction between the type of PGPR treatment and the application interval had no significant effect on all observed parameters, with the best results observed in the combination of bamboo root PGPR treatment with a 4-day application interval (M1I1). The highest fruit weight of 11.61 kg/plot (60.48 tons/ha) was obtained in the M1I1 treatment combination (bamboo root PGPR applied at 4-day intervals). The lowest fruit weight of 8.19 kg/plot (42.64 tons/ha) was obtained in the M2I3 treatment combination (PGPR from mimosa roots applied at 12-day intervals).

Abstract

This study aims at identifying the use of organic and anorganic mulch of the zucchini plants appropriate elephant manure inyorder to obtain optimal growth and yield. The study has been on, Boyolali Regency with an altitude of 170 m above sea level.Thishresearch method is an experiment using a factorial treatment Randomized Completed Block Design (RCBD) with 3 times. There are two kinds of treatment under the study that is dose of elephant manure and kind of  mulch, elephant manure dose treatment factor (G), there are 3 levels of treatment, namely (G1) Elephant manure dose 5 tons / ha, (G2) Elephant manure dose 10 tons / ha, (G3) The dose of elephant manure is 15 tons / ha, the treatment factor is mulch (M), there are 3 types of treatment, namely (M0) without mulch (M1) Silver mulch (M2) mulch straw.Therresults of this study show that treatment for the dose of elephant manure (G) showed no significant different to all observed parameters, the mulch type treatment (M) show highly significant to fruituweightoperlplantmand fruit diameter, show significant to fruit length, and biomassyfreshpweight per plant, while biomasydry weight per plant showed no significant effect. The interaction between elephant manure dose and mulch type (GxM) showed no significant to all observed parameters. The highest fruit weight yield was (478.84 g) in the treatment combination and the lowest was obtained in the treatment combination (253.05 g).
