Respon Pertumbuhan Aksesi Kemangi Pada Berbagai Komposisi Pupuk Nitrogen Alami

Abstract

Basil is not only useful as a vegetable, but also has many medicinal properties. This encourages thedevelopment of environmentally friendly basil cultivation, through the use of natural fertilizers.This study aims to determine the response of various basil accessions to the composition of sourceN fertilizer derived from cow urine, kipahit (Tithonia) compost and Urea. The study was conductedwith a factorial completely randomized design. The first factor is the accession of basil, namelyKemang, Ciaruten, Cijujug and Gasol. The second factor is the combination of N fertilizer (10levels), namely 100% N-Urea, 100% N- cow urine, 100% N-kipahit, 75% N-Urea + 25% N- cowurine, 75% N-Urea + 25 % N-kipahit, 50% N-Urea + 50% N-urine cow, 50% N-Urea + 50%kipahit, 25% N-Urea + 75% N-cow urine, 25% N-Urea + 75% N - kipahit, 0% N-Urea + 0% Ncow urine + 0% N-kipahit. The dosage of N fertilizer used is 150 kg N ha-1. The results showedthat the accession of basil which showed good growth and production was 'Ciaruten' and 'Gasol'.The application of Urea fertilizer composition with kipahit compost and Urea with cow urineproduces better growth and production compared to the use of Urea fertilizer or organic fertilizerseparately.Keywords: basil, cow urine, kipahit compost

Production and Quality of Seven Basil (Ocimum basilicum L.) Accessions in Various Composition of Urea Fertilizer and Mexican Sunflower Compost

“…Analysis of organic fertilizers showed that Mexican sunflower compost contained N of 2.69%, P2O5 0.99%, and K2O 4.96%. The products are relatively low compared to the previous study [18] that N content of Mexican sunflower compost is 3.90%, and Lestari [14] that Mexican sunflower contains 3.50-4.00% N, 0.35-0.38% P, 3.50-4.10% K. The total N content in compost has decreased because composting for 25-30 days with materials that have a high N content [19].…”

PERTUMBUHAN TANAMAN POHPOHAN (Pilea trinervia Wight) PADA BERBAGAI KOMPOSISI PUPUK NITROGEN ORGANIK

“…Menurut Gottimukkala et al (2019) Pemberian komposisi pupuk 75% N-Urea + 25% N-kompos kipahit juga menghasilkan jumlah tunas, panjang tunas total dan bobot basah dan kering panen setara dengan yang diberi 25% N-Urea + 75% N-urine sapi. Hal ini menunjukkan kemampuan kompos kipahit untuk menyediakan hara, terutama N, karena kandungan Nnya relatif tinggi, sebesar 3,76% (Rahayu et al 2021). walaupun dengan dengan porsi Urea yang lebih tinggi dibandingkan dengan urine sapi.…”

The Effect of Organic Liquid Fertilizer Chicken Eggshell with Onion Skin Waste For The Growth and Yield of Basil Plant (Ocimum basilium L.)

“…Diketahui penanaman secara anorganik dapat memiliki efek samping jika hasil pertaniannya dikonsumsi dalam jangka waktu yang panjang akibat residu kimia yang dimiliki pupuk anorganik, banyaknya penggunaan pestisida dan pupuk kimia sintetik secara terus menerus dalam jangka waktu yang panjang pada budidaya tanaman kemangi akan berdampak pada kesehatan konsumennya bahkan mampu mengubah kesuburan tanah tempat budidaya [6]. Selain itu, dikarenakan efektivitas penggunaan pupuk urea tidak bertahan lama maka pupuk urea digunakan secara berulang-ulang yang membuatnya menyebabkan perubahan struktur tanah, pemadatan, serta membuat kandungan unsur hara dalam tanah menurun dan mengalami pencemaran tanah.…”
