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.

Abstract

With an agroecological philosophy, the SRI (System of Rice Intensification) technique is a rice production technology approach that prioritizes soil, plant, and water management through local expertise and group empowerment based on environmentally beneficial activities. The purpose of this study is to investigate lowland rice growth and yield by using composted straw instead of NPK fertilizer. Implemented in Tara-Tara II village, West Tomohon sub-district for 5 (five) months with one factor treatment, namely the ratio of NPK fertilizer dose and straw compost dose: 100% NPK + straw compost 0% straw compost (P0), 75% NPK + 25% straw compost (P1), 50% NPK + 50% straw compost (P2), 25% NPK + 75% straw compost (P3), and 0% NPK + 100% straw compost (P4). The variables observed included: plant height, number of fodder, number of panicles/clumps, weight of 100 harvested dry grains, number of grains/panicles, percentage of smooth grains/clumps and harvested dry grain yield. Substitution of NPK fertilizer with compost straw has no effect on the height of lowland rice plants using the SRI (System of Rice Intensification) method, but does affect the number of productive tillers. The highest number of productive tillers was found in P2 (50% NPK + 50% straw compost), P3 (25% NPK + 75% straw compost) and P4 (0% NPK + 100% straw compost), with an average value of 31, respectively. 27; 28.20 and 27.53 tillers, while treatment P3 (25% NPK + 75% straw compost) and lower values in treatments P0 (100% NPK + 0% straw compost) and P1 (75% NPK + 25% straw compost ) with an average value of 25.83; and 25.67 offspring. Keywords: System of Rice Intensification (SRI), rice, straw compost.

Abstract. Edy Lengkong1*, Friska Malintoi 1, Jemmy Najoan1, Frangky J. Paat1, Tommy B. Ogie1, , Ronny Nangoi1. The Effectiveness Of Liquefied Organic Fertilizer (LOF) Market Waste On Increased Growth and Red-Spinach Production (Amarathus tricolor. L). Ekoton   11. 44-6. Red spinach (Amarathus tricolor L.) is a commodity that has very high development, it is proven that the number of requests tends to increase. Not inferior to other horticultural crops, red spinach plants have a fairly high economic value. Apart from being consumed every time, red spinach also contains nutrients needed by the body (Irwan et al., 2005). According to the Central Statistics Agency (BPS) in 2017, the total harvested area of ​​spinach in Indonesia in 2017 reached 40,608 hectares with a production of 160,248 tons ranks 9th out of 18 commercial vegetables cultivated and produced in Indonesia. There are 3 traditional markets in Manado City, namely Bahu Market in Malalayang District, Karombasan Market in Wanea District, and Bersehati Market in Wenang District. Can giving market waste POC affect the growth and yield of red spinach? The purpose of this study was to determine the effectiveness of giving market waste POC to the growth and yield of red spinach. And knowing the best POC concentration for the growth and yield of red spinach. It is hoped that this research can provide information on the use of market waste as a source of nutrients for the growth and yield of red spinach in the form of liquid organic fertilizer (POC). This research was arranged using a Randomized Block Design (RAK) with 5 treatments of POC concentration of market waste on red spinach plants. P0: control, P1: 25%, P2: 50%, P3: 75%, P4:100%. Each treatment consisted of 5 plant samples and was repeated 3 times to obtain 75 samples. Market waste POC with a concentration of 75% is the best concentration on the variable height of red spinach plants. Keywords: POC, Red Spinach, Market Garbage

Abstract

To achieve sustainable and environmentally friendly agriculture, organic-based rice cultivation techniques utilising local resources are gaining popularity. Biosaka, a plant extract solution, functions as an elicitor with the potential to increase plant productivity. This study aimed to analyse: (1) the single effect of Biosaka application time on the growth and production of lowland rice; (2) the single effect of Biosaka concentration on the growth and production of lowland rice; and (3) the interaction between application time and concentration in influencing the growth and production of lowland rice. The study was conducted in Taratara Dua Village, West Tomohon District, Tomohon City, from April to October 2024. This field study used IR-64 rice varieties and a randomised block design with two factors: application time (5, 10, and 15 days) and concentration (0, 30, and 60 ml/15 L). The variables measured included plant height, number of productive tillers, panicle length, and grain yield. The results showed no interaction between the two factors. Although the application time factor did not significantly affect any variables, the Biosaka concentration significantly affected the number of productive tillers, panicle length, the number of filled and empty grains, and the dry grain yield per plot. Interestingly, this study achieved the highest yield in the control treatment (0 ml/L), with a dry grain yield of 6.19 kg per plot. This indicates that the Biosaka application, at the concentration tested, did not increase rice yield in this study.
