Abstract

ABSTRACT The purpose of the research was to studied the application of gliricidia MOL on the growth and yield of lowland rice in the salibu method, and to get the best concentration of gliricidia liquid organic fertilizer  (POC) on the growth and production of lowland rice. Field research has been conducted in Tababo Village, Subdistrict of Belang, district of Southeast Minahasa. The treatment in the experiment consists of one treatment factor, that were concentrations of gliricidia POC, ie  : 0, 50 , 100, 150, and 200 ml/litre. The results showed that gliricidia POC  have an effect on plant height, the number of  grain/panicle, and the dry grain yield (GKP) / plot, but not affect the number of productive tillers and weight of 1,000 grain. The best results were achieved in gliricidia POC concentration 200 ml/litre  with the highest values were: plant height was 98.93 cm; 116.420 grain/panicle; and 8.300 kg dry grain yield or equivalent to 6.92 ton/ha.Keywords : gliricidia POC, production, lowland rice,  salibu method

Abstract

ABSTRACT   This study aimed to examine the growth and production of potato crop varieties and varieties Granola Supejhon on two altitude, which is 750 m above sea level and 1200 m above sea level, studies using randomized block design with two factors. The first factor is the Granola variety and Supejhon. The second factor is the altitude, which is 750 m above sea level and 1200 m asl. The results of this study indicate that the rate Crop Growth Rate (LTT) and the Tuber Growth Rate (LTU) of Supejhon Granola varieties have a much higher altitude 1200 m asl (Modoinding) compared with altitude 750 m asl (Langowan). The altitude effect on the number of tubers / plant and production / plot, otherwise varieties had no effect on the number of tubers / plant, weight of tubers / plot and production / plot, and there is no interaction between variety and altitude. At altitude 750 m asl, both varieties yield an average production of tubers / plot of 1343.20 g (1.34 kg), whereas the altitude of 1200 m asl generate 7462.18 g (7.46 kg). Based on the average, the weight of tubers / plant and production / plots at very low reached by the two varieties of Granola and Supejhon well, so that the two varieties are not recommended to be cultivated at altitude 750 m above sea level. Further research is needed to examine other potato varieties that can be cultivated in areas with altitude of 750 m asl. Keywords: Potato, growth, production, level altitudes ABSTRAK Penelitian ini bertujuan untuk mengkaji pertumbuhan dan produksi tanaman kentang varietas Granola dan varietas Supejhon pada dua ketinggian tempat, yaitu 750 m dpl dan 1200 m dpl, penelitian  menggunakan Rancangan Acak Kelompok dengan dua faktor.  Faktor pertama adalah varietas  Granola dan Supejhon.  Faktor kedua adalah ketinggian tempat, yaitu 750 m dpl dan 1200 m dpl. Hasil penelitian ini menunjukkan bahwa Laju Tumbuh Tanaman (LTT) rata-rata dan Laju Tumbuh Umbi (LTU) rata-rata varietas Granola dan Supejhon memiliki nilai yang jauh lebih tinggi pada ketinggian tempat 1200 m dpl (Modoinding) dibandingkan dengan ketinggian tempat 750 m dpl (Langowan).  Ketinggian tempat berpengaruh terhadap jumlah umbi/tanaman dan produksi/petak, sebaliknya varietas tidak berpengaruh terhadap jumlah umbi/tanaman, bobot umbi/petak dan produksi/petak, serta tidak terdapat interaksi antara varietas dan ketinggian tempat. Pada ketinggian tempat 750 m dpl, kedua varietas menghasilkan rata-rata produksi umbi/petak sebesar 1343,20 g (1,34 kg), sedangkan pada ketinggian tempat 1200 m dpl menghasilkan 7462,18 g (7,46 kg).  Berdasarkan nilai rata-rata, bobot umbi/tanaman dan produksi/petak yang sangat rendah dicapai oleh kedua varietas baik Granola maupun Supejhon, sehingga kedua varietas tersebut tidak dianjurkan untuk dibudidayakan pada ketinggian 750 m dpl.  Perlu dilakukan penelitian lanjutan untuk menguji varietas kentang lainya yang dapat dibudidayakan pada daerah dengan ketinggian tempat 750 m dpl.

Abstract

Spinach (Amaranthus sp) is a plant belonging to the Amaranthaceae family. Spinach is one of the oldest food plants in the world originating from America, which has been cultivated around 6700 years BC and is now spread throughout tropical and subtropical areas throughout the world. Copra fumigation ash contains macro and micro nutrients that plants need, one of which is potassium. This research aims to determine the effect of copra fumigation ash on the growth of spinach plants. This research was carried out at the Green House, Faculty of Agriculture, Sam Ratulangi University, Manado, North Sulawesi from June to July 2024. This research used a Randomized Group Design (RAK) with six treatments and four replications consisting of Without Ash Copra Fumigation (K0), 5 tons Copra Fumigation Ash/ha (K1), 10 tonnes of Copra Fumigation Ash/ha (K2), 15 tonnes of Copra Fumigation Ash/ha (K3), 20 tonnes of Copra Fumigation Ash/ha (K4) and 25 tonnes of Copra Fumigation Ash/ha ( K5). The research data were analyzed using the F test using the Microsoft Office Excel program to determine the effect of copra fumigation ash treatment on the growth of spinach plants. The research results showed that copra fumigation ash had a significant effect on the variable height of spinach plants but not on the number of leaves and width of spinach leaves. Copra fumigation ash also has a very significant effect on the fresh weight of spinach plants. It is recommended to use copra ash at a dose of 20 tons/ha as the recommended dose for spinach cultivation activities.
