Aplikasi Pupuk Gliocompost dalam Meningkatkan Efisiensi Pemupukan dan Pertumbuhan Tanaman Selada Keriting (Lactuca sativa L.).

Abstract

Tanaman selada (Lactuca sativa L.) merupakan salah satu komoditi hortikultura yang memiliki nilai ekonomis, kandungan gizi dan mineral yang cukup tinggi. Permintaan pasar terhadap selada yang terus meningkat, membuka peluang pasar yang semakin besar. Penggunaan pupuk organik hayati Gliocompost berpotensi meningkatkan kesuburan tanah dan produktivitas selada dengan memperbaiki struktur tanah dan meningkatkan aktivitas mikrob. Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi dosis pupuk organik hayati Gliocompost dan NPK terhadap karakteristik biologi dan kimia tanah, serta pertumbuhan tanaman selada keriting. Perlakuan disusun dalam Rancangan Acak Lengkap (RAL) satu faktor yaitu kombinasi dosis pupuk Gliocompost dan NPK yang terdiri terdiri dari P0 = (Kontrol), P1 = (100% NPK), P2 = (Gliocompost), P3 = (Gliocompost + 50% NPK), P4 = (Gliocompost + 75% NPK), kemudian pada masing-masing perlakuan memiliki 3 ulangan, sehingga terdapat total 15 petak percobaan dengan ukuran 120 cm x 80 cm dan jarak tanam 30 cm. Hasil penelitian ini menunjukkan bahwa kombinasi Gliocompost dan NPK 75% meningkatkan kandungan populasi total mikrob dan fungi, serta pada karakteristik kimia seperti pH, C-Organik, N-total, dan K-total. Pertumbuhan tanaman menunjukkan korelasi positif antara kombinasi dosis pupuk gliocompost dan NPK melalui nilai pertumbuhan tinggi tanaman dan jumlah daun tanaman dengan dosis terbaik yaitu pada perlakuan P4 (Gliocompost + 75% NPK) untuk tanaman selada (Lactuca sativa L.).

Lettuce (Lactuca sativa L.) is one of the horticultural commodities that has economic value, high nutritional and mineral content. Market demand for lettuce continues to increase, opening up greater market opportunities. The use of biological organic fertilizer Gliocompost has the potential to increase soil fertility and lettuce productivity by improving soil structure and increasing microb activity. This study aims to determine the effect of the application of Gliocompost and NPK biological organic fertilizer doses on soil biological and chemical characteristics, as well as the growth of curly lettuce plants. The treatments were arranged in a one-factor Completely Randomized Design (CRD), namely a combination of Gliocompost and NPK fertilizer doses consisting of P0 = (Control), P1 = (100% NPK), P2 = (Gliocompost), P3 = (Gliocompost + 50% NPK), P4 = (Gliocompost + 75% NPK), then each treatment had 3 replicates, so there were a total of 15 experimental plots with a size of 120 cm x 80 cm and a spacing of 30 cm. The results of this study showed that the combination of Gliocompost and 75% NPK increased the total population content of microbes and fungi, as well as on chemical characteristics such as pH, C-Organic, N-total, and K-total. Plant growth showed a positive correlation between the combination of gliocompost and NPK fertilizer doses through the growth value of plant height and number of plant leaves with the best dose in the P4 treatment (Gliocompost + 75% NPK) for lettuce plants (Lactuca sativa L.).
