Abstract

ABSTRAKRendahnya produksi padi gogo disebabkan masih banyaknya yang menanami lahan kering dengan padi gogo varietas lokal yang berumur panjang. Upaya meningkatkan produksi padi gogo dilakukan dengan sistem tanam jajar legowo. Penelitian ini bertujuan untuk mengetahui pengaruh sistem tanam dan jumlah bibit/lubang tanam terhadap pertumbuhan tanaman padi gogo. Penelitian dilaksanakan di lahan percobaan Fakultas Pertanian Universitas Samudra, Kota Langsa Provinsi Aceh. Penelitian dilakukan bulan November 2022 sampai April 2023. Penelitian disusun menggunakan rancangan acak kelompok (RAK) faktorial yang terdiri dari 2 faktor. Faktor pertama adalah sistem tanam yang terdiri T1 (jajar legowo) dan T2 (Tegel). Faktor kedua adalah jumlah bibit/lubang tanam yang terdiri J1 (1 bibit), J2 (2 bibit) dan J3 (3 bibit). Parameter yang diamati antara lain: tinggi tanaman (cm) dan jumlah anakan yang diamati pada umur 14, 28, 42, 56, 70, dan 84 HST, jumlah anakan produktif, umur keluar malai, panjang malai, umur panen dan produksi/tanaman. Hasil penelitian menunjukkan bahwa semua interaksi perlakuan sistem tanam dan jumlah bibit/lubang memberikan tinggi tanaman padi yang sama, kecuali penanaman bibit sistem tegel dengan 1 bibit/lubang tanam memiliki tinggi tanaman yang paling rendah. Jumlah anakan terbanyak didapat pada interaksi perlakuan sistem jajar legowo dengan bibit 3 bibit/lubang tanam dan interaksi sistem penanaman secara tegel dengan 3 bibit/lubang tanam, yaitu berturut-turut sebanyak 19.68 dan 17.10. Tetapi interaksi kedua perlakuan tidak berpengaruh nyata pada parameter produksi padi. Masing-masing perlakuan sistem tanam jajar legowo dan 3 bibit/lubang tanam memberikan jumlah anakan produktif (16.04 dan 17.33) dan produksi/tanaman yang paling tinggi (65.54 g/tanaman dan 73.68 g/tanaman). ABSTRACTThe low production of upland rice is due to the fact that many people still plant dry land with local varieties of upland rice that have a long life. Efforts to increase upland rice production are carried out using the jajar legowo planting system. This study aimed to determine the effect of the planting system and the number of seedlings/planting holes on the growth of upland rice plants. The study was conducted in the experimental field of the Faculty of Agriculture, Samudra University, Langsa City, Aceh Province. The study was conducted from November 2022 to April 2023. The study was arranged using a factorial randomized block design (RAK) consisting of 2 factors. The first factor was the planting system consisting of T1 (jajar legowo) and T2 (Tegel). The second factor was the number of seedlings/planting holes consisting of J1 (1 seedling), J2 (2 seedlings) and J3 (3 seedlings). The parameters observed include: plant height (cm) and number of tillers observed at the ages of 14, 28, 42, 56, 70, and 84 HST, number of productive tillers, panicle emergence age, panicle length, harvest age and production/plant. The results showed that all interactions of planting system treatments and the number of seedlings/holes gave the same rice plant height, except for the tile system seedling planting with 1 seedling/planting hole which had the lowest plant height. The highest number of tillers was obtained in the interaction of the jajar legowo system treatment with 3 seedlings/planting hole and the interaction of the tile planting system with 3 seedlings/planting hole, which were 19.68 and 17.10, respectively. However, the interaction of the two treatments did not significantly affect the rice production parameters. Each treatment of the jajar legowo planting system and 3 seedlings/planting hole gave the highest number of productive tillers (16.04 and 17.33) and production/plant (65.54 g/plant and 73.68 g/plant).

Abstract

ABSTRAK           Unsur iklim erat hubungannya dengan cuaca yang dapat menurunkan suatu usaha budidaya. Salah satu unsur iklim yang berpengaruh terhadap pertumbuhan dan produktivitas tanaman yaitu angin. Kecepatan angin memegang peran penting dalam evapotranspirasi, karena sebanding dengan evapotranspirasi. Data evapotranspirasi digunakan untuk kepentingan sumber daya air dan menghitung kesetimbangan air khususnya keperluan penentuan kebutuhan air bagi tanaman dalam periode pertumbuhan dan produksi tanaman sorgum. Penelitian ini bertujuan untuk menentukan bagaimana kecepatan angin dan evapotranspirasi mempengaruhi pertumbuhan dan produksi tanaman sorgum. Penelitian dilakukan di lapangan percobaan Stasiun Klimatologi BMKG Aceh, Aceh Besar. Metode penelitian yang digunakan meliputi analisa regresi linier berganda, uji T, uji F, koefisien korelasi dan koefisien determinasi. Parameter penelitian meliputi tinggi tanaman, jumlah daun, berat basah/tanaman dan berat basah/plot. Hasil penelitian menunjukkan bahwa kecepatan angin berpengaruh terhadap bobot basah tanaman dan bobot basah/plot. Evapotranspirasi berpengaruh secara parsial terhadap tinggi tanaman, jumlah daun dan bobot basah/plot. Hasil analisa uji F simultan menunjukkan bahwa kecepatan angin dan evapotranspirasi memiliki pengaruh secara simultan terhadap tinggi tanaman. Kecepatan angin menunjukkan hubungan yang kuat terhadap tinggi tanaman, jumlah daun, dan bobot basah/plot, serta memiliki hubungan yang cukup berarti terhadap terhadap produksi bobot basah tanaman/plot.  ABSTRACT           Climate elements are closely related to weather which can reduce a cultivation business. One of the climate elements that influences plant growth and productivity is wind. Wind speed plays an important role in evapotranspiration, because it is proportional to evapotranspiration. Evapotranspiration data is used for water resources purposes and calculating water balance, especially for determining water needs for plants during the growth and production period of sorghum plants. This research aimed to determine how wind speed and evapotranspiration affect the growth and production of sorghum plants. The research was carried out at the experimental field of the BMKG Aceh Climatology Station, Aceh Besar. The research methods used include multiple linear regression analysis, T test, F test, correlation coefficient and coefficient of determination. Research parameters included plant height, number of leaves, wet weight/plant and wet weight/plot. The results showed that wind speed had an effect on plant wet weight and wet weight/plot. Evapotranspiration partially influences plant height, number of leaves and wet weight/plot. The results of the simultaneous F test analysis showed that wind speed and evapotranspiration had a simultaneous influence on plant height. Wind speed showed a strong relationship with plant height, number of leaves, and fresh weight/plot, and had a significant relationship with the production of fresh weight of plants/plot.
