Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk kandang sapi,

Bacillus sp., dan pupuk NPK terhadap perubahan sifat kimia tanah, serapan hara NPK,

dan pertumbuhan vegetatif tanaman bawang merah. Pengambilan sampel tanah

dilakukan pada awal sebelum perlakuan dan pada saat selesai masa inkubasi.

Pengambilan sampel tanaman dilakukan pada masa vegetatif maksimum yaitu 35 HST.

Penelitian ini dilakukan di lahan pasir pantai Samas, Bantul. Pada bulan Januari 2023 –

Maret 2023. Rancangan penelitian ini menggunakan kombinasi pupuk kandang sapi 0,

10, dan 20 ton/ha dengan penambahan Bacillus sp., serta pupuk NPK pada tanaman

bawang merah. Data yang diperoleh dari penelitian dianalisis menggunakan analisis

sidik ragam, apabila terdapat pengaruh nyata, maka dilanjutkan dengan uji DMRT taraf

5%. Hasil penelitian menunjukkan bahwa perlakuan pupuk kandang sapi 10 ton/ha

berpengaruh nyata terhadap C-organik tanah, serapan N tanaman, dan serapan P

tanaman tetapi tidak berpengaruh nyata terhadap pH tanah, serapan K tanaman, tinggi

tanaman, dan jumlah daun. Perlakuan Bacillus sp. berpengaruh nyata terhadap C-organik tanah, serapan N tanaman, dan serapan P tanaman tetapi tidak berpengaruh

nyata terhadap pH tanah, serapan K, tinggi tanaman dan jumlah daun. Pemberian pupuk

NPK berpengaruh nyata terhadap C-organik tanah, serapan N tanaman, serapan P

tanaman, dan jumlah daun tetapi tidak berpengaruh nyata terhadap pH tanah, serapan K

tanaman, dan tinggi tanaman. Interaksi pemberian pupuk kandang sapi, Bacillus sp., dan

pupuk NPK berpengaruh nyata terhadap C-organik tanah, serapan N tanaman, dan

serapan P tanaman tetapi tidak berpengaruh nyata terhadap ph tanah, serapan K

tanaman, tinggi tanaman dan jumlah daun.

The research aimed to determine the effect of applying cow manure, Bacillus sp., and

NPK fertilizer to changes in soil chemical properties, NPK nutrient uptake and

vegetative and generative growth of shallot plant. Soil samples were taken at the

beginning before and at the end of the incubation period. Meanwhile, sampling of plants

was carried out during the maximum vegetative period, which was 33 HST. This

research was conducted at Samas beach sand land, Bantul from January 2023 to March

2023. The data obtained from the research was analyzed using analysis of variance, if

there was a real impact, then it was continued with the DMRT test at the 5% level. The

results showed that the treatment of giving cow manure had a significant effect on the

uptake of N, P, and K. The results showed that 10 tons/ha of cow manure treatment had

a significant effect on carbon organic, soil N-uptake, and P uptake, but had no

significant effect on soil pH, K uptake, plant height, and number of leaves. Treatment of

Bacillus sp. had a significant effect on carbon organic, soil N-uptake, and P uptake but

had no significant effect on soil pH, K uptake, plant height and number of leaves. The

application of NPK fertilizer had a significant effect on carbon organic, N uptake, P

uptake, and number of leaves but had no significant effect on soil pH, K uptake, and

plant height. The interaction of giving cow manure, Bacillus sp., and NPK fertilizer has

a significant effect on carbon organic, N uptake, and P uptake but has no significant

effect on soil pH, K uptake, plant height and number of leaves.
