“…Rice plants grow optimally when under normal conditions, namely in conditions that are not flooded and not stressed by drought. Rice growth will be stable under normal conditions [8]. The application of Zn nutrients affects the plant height of mentik wangi rice plants under stressed conditions.…”

Mentik wangi rice (Oryza sativa L.) is a variety originating from Magelang Regency, Central Java. Mentik wangi has the advantages of fragrant smell, fluffier texture, and high market demand. The weakness of mentik wangi rice is long life (4 months), long stems, easy collapse. The problem of long-lived rice if the planting period enters the dry season and the availability of water is limited, it will have an impact on productivity. This study aims to overcome problems by applying Zn nano to drought stress. Zn is one of plant microelements that functions as auxin biosynthesis, cell elongation, stem segments, and enzyme activator. Enzyme activators function in slowing the increase in reactive oxygen species (ROS) during drought stress, maintaining physiological resistance and rice growth. The study was conducted with a factorial completely randomized design in a screen house. The results showed Zn nano maintains yield and plant growth under stress. The most optimal dose. However, there is a tendency at the 3.75 ppm Zn nano dose to get low yields, it is suspected that if an excessive dose of Zn causes poisoning in plants. The application of Zn nano is optimal when applied under stressed conditions compared to normal conditions.

“…Perlakuan J3 akan menyebabkan pemanfaatan energi matahari menjadi lebih baik dari pada J1 (Aribawa, 2012). Selain itu penggunaan model jarak tanam jajar legowo 2:1 berpeluang memiliki populasi padi yang banyak dibandingkan J2 (Ikhwani et al, 2013). Keadaan ini akan menjadi lebih baik bila kedalamnya diberikan pupuk bokasi yang cukup, yaitu 15 ton/ha (P3), karena akan menyebabkan terjadinya penambahan unsur hara ke dalam tanah yang cukup banyak (Rozen dan Kasim, 2018).…”

This research aims to determine the real interaction between bokashi dose treatment and spacing models on the growth and yield of paddy plants. The study used a 3 x 3 factorial with 3 replications. The first factor was the spacing model which consists of 3 levels, namely J1 = tile spacing model (20 x 20 cm), J2 = Jajar Legowo 4:1 (20 cm x 40 cm x 10 cm), and J3 = Jajar Legowo 2:1 (20 cm x 40 cm x 10 cm). The second factor was the dosage of bokashi fertilizer which consists of 3 levels, namely P1 = 5 tonnes per hectare, P2 = 10 tonnes per hectare, and P3 = 15 tonnes per hectare. The research discovered that there was an interaction effect on plants aged 45 days after planting as well as an increase in yield in the form of an increase in grain weight per plant clump. Model treatment also had a significant effect on plant height at the age of 15 and 30 days after planting. In addition, there were also changes in the number of tillers, productive tillers, seeds per panicle, panicle length, and grain weight per plot for all observed ages. The 4:1 legowo row model treatment resulted in the best growth and production of paddy fields, while the highest production was produced by the legowo row 2:1 treatment. Bokashi dosage treatment was 15 tons per hectare.Isi artikel ini bertujuan mengetahui adanya interaksi yang nyata antara perlakuan dosis bokasi dan model jarak tanam terhadap pertumbuhan dan hasil tanaman padi. Penelitian menggunakan rancangan acak kelompok (RAK) faktorial 3 x 3 dengan 3 kali ulangan. Faktor pertama adalah model jarak tanam yang terdiri dari 3 taraf, yaitu J1 = model jarak tegel (20 x 20 cm), J2 = Jajar Legowo 4 :1 (20 cm x 40 cm x 10 cm), dan J3 = Jajar Legowo 2 : 1 (20 cm x 40 cm x 10 cm). Faktor kedua adalah dosis pupuk bokashi yang terdiri dari 3 taraf yaitu P1 = 5 ton/ha, P2 = 10 ton/ha, dan P3 = 15 ton/ha. Riset yang dilakukan membuktikan bahwa adanya pengaruh interaksi pada tanaman umur 45 hari serta peningkatan hasil panen berupa berat gabah per rumpun yang mengalami kenaikan. Perlakuan model juga memiliki pengaruh nyata terhadap tinggi tanaman pada usia 15 dan 30 hari sejak masa tanam. Selain itu juga adanya perubahan pada jumlah anakan, anakan produktif, biji per malai, panjang malai, dan berat gabah per petak semua umur pengamatan. Perlakuan model jajar legowo 4 : 1 menghasilkan pertumbuhan dan produksi padi sawah pertanaman paling baik, sedangkan produksi paling tinggi dihasilkan oleh perlakuan jajar legowo 2 : 1. Perlakuan dosis bokasi 15 ton/ha

“…The yield of rice cv. Inpara 1 and 4 in jarwo cropping system was higher than that in tegel cropping system , the varieties of Air Tenggulang, Banyuasin, Dendang, Inpara 2, Inpara 3, and Inpara 5 showed no significant differences in grain yield when planted in tegel and jarwo cropping systems (Ikhwani and Makarim, 2012). The research aimed to determine of the effect of cropping systems and varieties on the rice growth and yield in acid sulfate soils of the tidal swamplands.…”

Swampland plays a critical function in agriculture, specifically in growing rice production. The study aimed to determine the effects of cropping systems and varieties on the rice growth and yield in acid sulfate soil of tidal swampland. The experiment was conducted in a potential acid sulphate soils in Kapuas Regency, Central Kalimantan Province. The experiment was arranged in a split plot design with three replications. The main plot consisted of three HYV’s of rice, namely Inpara 8, Inpari 32, and Margasari. The subplot consisted of five cropping systems, namely, Jarwo 2:1A, Jarwo 2:1B, Jarwo 2:1C, Hazton, and Tegel. The plot size was 4 m x 5 m. The variables observed included initial soil properties, plant growth, and yield components. The jajar legowo cropping system in this study was not able to increase rice yields in acid sulphate soil. There was an interaction effect of cropping systems and varieties on the plant height and number of tillers at vegetative phase. At generative and pre-harvest phases, there was significant single effect of variety and cropping system in the planting height and number of tillers, respectively. Both cropping system and variety significantly affected the number of panicles per hill, while panicle length, grain per panicle and grain yield were only affected by variety. There was no significant effect of both factors on the number of filled grains per panicle. Inpara 8 variety achieved the highest grain yield, which was 6.78 ton.ha-1 or equivalent to 4.34 ton.ha-1 of 14 % water content.
