Abstract

Sistem tanam (ST) yang sering digunakan petani yaitu ST tegel. Sampai sekarang masih banyak petani yang menggunakan bibit lebih dari tujuh batang per lubang tanam (BpLT). Tujuan penelitian adalah untuk mempelajari respon tanaman padi terhadap  ST dan jumlah bibit per lubang tanam (JBpLT). Penelitian dilakukan di Desa Raman Aji, Kecamatan Raman Utara, Lampung Timur pada bulan Februari sampai Mei 2016.  Perlakuan disusun dalam Rancangan Kelompok Teracak Lengkap dengan pola split plot.  Petak utama adalah ST jarwo 2:1, ST Jarwo 4:1, dan ST tegel 25 x 25 cm. Anak petak terdiri atas JBpLT: 1 BpLT, 2 BpLT, dan 3 BpLT. Data dianalisis ragam dan dilanjutkan uji orthogonal  kontras, semua pengujian dilakukan pada taraf 5%.  Hasil percobaan menunjukkan bahwa (1) ST jarwo 2:1 dan ST jarwo 4:1 meningkatkan pertumbuhan padi hibrida Mapan P-05 dibandingkan ST tegel 25 x 25 cm, (2) penanaman 1 BpLT meningkatkan komponen hasil padi dibandingkan penanaman 2 BpLT dan 3 BpLT, dan (3) penanaman 1 BpLT memberikan hasil GKG (6,86 t ha-1) yang lebih tinggi dari penanaman 2 BpLT (5,64 t ha-1) dan 3 BpLT (4,59 t ha-1) pada ST jarwo 2:1, ST jarwo 4:1 dan ST tegel 25 x 25 cm, secara berurutan.AbstractThe common planting system (PS) used by the farmers is Tegel system. Yet, many farmers still use more than seven seeds per planting hole (SpPH). The research objective was to study the reponse of rice plants to the planting system and the number SpPH. The research was conducted in Raman Aji Village, Raman Utara, East Lampung from February to May 2016. The treatments were arranged in a RCBD with a split plot pattern (the main plot were the PS i.e. jarwo 2: 1, jarwo 4: 1 and “Tegel” 25 x 25 cm; the subplots are the number of SpPH i.e. 1 SpPH, 2 SpPH, and 3 SpPH). The results showed that (1) the jarwo 2: 1 system increased rice growth compared to the 25 x 25 cm “Tegel”; (2) application of 1 SpPH increased the yield  component  of rice compared to planting 2 SpPH and SpPH; and (3) application of 1 SpPH (6.86 t ha-1) gave the higher weight of milled grain than using 2 SpPH (5.64 t ha-1) and 3 SpPH (4.59 t ha-1), both planted in the jarwo 2:1, jarwo 4:1 and 25 x 25 cm  “Tegel” System

Abstract

Liquid organic fertilizer is fertilizer that is applied to the leaves. The advantage of fertilizer application through leaves is that nutrients are more easily absorbed by plants, both macro and micro nutrients. This study aims to determine the time intervals of fertilization and differences in the concentration of liquid organic fertilizer on the growth and yield of red spinach, as well as to determine the interaction between the two. The treatment used was the time of fertilization and the difference in the concentration of liquid organic fertilizer. The results showed that the timing of fertilization had a significant effect on the weight of red spinach plants. The time interval of fertilization every 3 days gave better results, namely 18.94 g. And there is no interaction between time interval and concentration of liquid organic fertilizer on the growth and yield of red spinach for all variables.

Abstract

Dragon fruit is one type of plant that is quite popular in Indonesia because of its sweet taste and high selling price. Dragon fruit has various types, including dragon fruit with red flesh, white flesh with yellow skin color and red skin with white flesh. Dragon fruit contains high betacharotene and antioxidants to prevent cancer and ward off free radicals. The fiber content in it can facilitate digestion, prevent colon cancer, and cope with diabetes. The objectives of this study were to determine effect of length stem cuttings on the growth of red dragon fruit cuttings, effect of different methods of giving between immersion and watering coconut water on the growth of dragon fruit cuttings, and interaction lengths cuttings and how to give coconut water to the growth of dragon fruit cuttings. The results showed that red dragon fruit stem lengths of 25 cm and 30 cm give better results than 15 cm and 20 cm. Dragon fruit stem lengths of 25 cm and 30 cm had a significant effect on bud emergence variables, number of shoots, average shoot length per cuttings and number of roots, but the root length variables, root wet weight and root shoot ratio were not significantly different. The method of giving coconut water shows that watering is better than soaking. but on the variable number of shoots per cuttings, the average length of shoots per cuttings, root wet weight and root crown ratio had no significant effect. There is no interaction between rod length and means giving coconut water to the growth of red dragon fruit cuttings on all observed variables.

Abstract

Organic fertilization of cow manure bokashi and inorganic fertilizer SP-36 is an alternative to improve soil fertility in red-yellow podzolic soil. However, due to its slow availability, the application of this fertilizer from previous plantings still leaves residue to improve the quality of mung beans in subsequent plantings. The aims of the study were to determine: 1) The effect of various residual doses of bokashi fertilizer on the growth and yield of mung bean. 2) The effect of various residual doses of SP-36 fertilizer on the growth and yield of mung bean. 3) Interaction of various doses of bokashi and SP-36 fertilizer residues on the growth and yield of mung bean. The research was carried out in the experimental garden of the Dharma Wacana College of Agricultural Sciences, Margorejo Subdistrict, Metro City, from February to April 2021. The study used a Complete Randomized Block Design which was arranged in a factorial manner with three replications. The first factor was residues of cow manure Bokashi fertilizer (B) which consisted of three levels, namely dose of 5 tons/ha (b1), 10 tons/ha (b2), and 15 tons/ha (b3). The second factor was SP-36 (P) fertilizer residue which also consisted of three levels, namely dose of 150 kg/ha (p1), 200 kg/ha (p2), and 250 kg/ha (p3). The results showed that residues of various doses of bokashi and SP-36 had no significant effect. No interaction was found between residues of bokashi fertilizer and SP-36 on the growth and yield of mung bean. However, mung beans show a fairly good production.
