Abstract

ABSTRACT This research aims to study the increase of the yields of sweet corn and soil fertility by applying integrated fertilizers management system in Jajar Legowo 2:1 planting system. The results of this research show that providing the 25% inorganic fertilizers plus 75% organic fertilizers as treatment has given better result for the yields of sweet corn than providing 100% inorganic fertilizers or 100% organic fertilizers as treatment. Chemical properties of the soil before and after the treatment of fertilizers, it is found out that the contents of C-Organic, N of soil, and K2O of the researched soil are categorized as low to very low. However, it is found out that the available content of P2O5 has increased by 4.29 ppm through the 25% inorganic fertilizers plus 75% organic fertilizers as treatment and has increased by 1.73 ppm through the 100% organic fertilizers as treatment.

Abstract

ABSTRACT The aim of the research was to studied the application of gliricidia MOL on the growth and yield of lowland rice in the SRI method, and to get the best time of gliricidia MOL application on the growth and production of lowland rice. Field research has been conducted in Tara-Tara II Village, West Tomohon Subdistrict for five months starting from June 2017 until November 2017. Treatment in the experiment consists of one treatment factor, that was interval time of gliricidia MOL application, ie  : 0, 5 , 10, 15, and 20 days. The results showed that time application of gliricidia MOL have an effect on the number of productive tillers, the number of filled grain/panicle, the number  of empty grain/panicle, and the dry grain yield (GKP) / plot, but not affect the plant height. The best results were achieved in gliricia MOL application on interval time every 15 days with a values were : 28.66 productive tillers; 176.90 fillet grain/panicle; 19.80 empty grain/panicle (lowest); and 9.50 kg dry grain yield or equivalent to 7.92 ton/ha.Keywords: gliricidia MOL, production, lowland rice,  System of Rice Intensification  (SRI)

Abstract

Penggunaan pupuk kimia dengan dosis yang tinggi dan dalam jangka waktu yang panjang berdampak terhadap penurunan kesuburan lahan pertanian. Hal tersebut menyebabkan kondisi tanah menjadi asam, padat, dan mengurangi aktivitas mikroorganisme di dalam tanah, sehingga diperlukan upaya untuk mengatasi masalah kesuburan tanah, yaitu dengan penambahan bahan organik seperti pemberian pupuk kandang, kompos padat maupun pupuk organik cair (POC).  Penelitian ini bertujuan untuk : (1) mengkaji pengaruh POC daun gamal pada pertumbuhan dan produksi jagung manis, (2) mendapatkan dosis POC yang terbaik untuk  meningkatkan pertumbuhan dan produksi jagung manis.  Penelitian dilaksanakan di Kelurahan  Walian Kota Tomohon Sulawesi Utara, pada bulan April 2019 sampai dengan Agustus 2019. Penelitian disusun dengan  menggunakan Rancangan Acak Kelompok (RAK). Faktor yang diteliti adalah konsentrasi POC daun gamal, yang terdiri atas : 0,50, 100, 150, dan 200 ml per liter air. Variabel yang diamati meliputi : tinggi tanaman, jumlah daun, panjang tongkol, diameter tongkol, dan bobot tongkol.  Data dianalisis dengan analisis ragam dan dilanjutkan dengan uji beda nyata terkecil (BNT) 5%.  Hasil penelitian menunjukkan bahwa pemberian POC daun gamal berpengaruh terhadap tinggi tanaman, jumlah daun, panjang tongkol, diameter tongkol, dan bobot tongkol. Nilai tertinggi dicapai pada pemberian 200 ml POC daun gamal, dengan kenaikan panjang tongkol, diameter tongkol, dan bobot tongkol masing-masing sebesar 18,51% ; 8,03% ; 6,55% ; 5,36% dan 24,52% dibandingkan dengan kontrol.
