Abstract

Saturated soil culture (SSC) is a cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. By keeping the water-table constantly, soybean will be avoided from negative effect of inundation on soybean growth because soybean will acclimatize and improve its growth. The objective of the research was to study the response of soybean varieties under saturated soil culture on tidal swamps. The research was conducted at Banyu Urip of  Tanjung Lago Sub District, Banyuasin District, South Sumatera Province, Indonesia from April to August 2009. The experiment was arranged in a split plot design with three replications. The main plot was water depth in the furrow consisted of without watering, 10, 20, 30, 40 cm under soil surface (uss). The subplot was soybean variety consisted of Tanggamus, Slamet, Willis, and Anjasmoro. The result showed that the interaction between varieties and water depth significantly affected growth and seed production, except pod numbers/plant. The values of all variables were higher under SSC compared to those cultivated without watering (control), but varieties responded to SSC differently. The highest seed production was obtained from Tanggamus with 40 cm uss, i.e. 4.83 ton/ha but it was not significantly different from those at water depth 20 (4.63 ton/ha) and 30 cm uss (4.71 ton/ha). However, technically and economically, 20 cm uss was the most appropriate water depth for soybean production on tidal swamps.   Key words: Glycine max L. (Merr.), water management, water table

Abstract

Saturated soil culture (SSC) technology appropriate to prevent pyrite oxidation on tidal swamps and has been proved to increase the productivity of soybean on non-tidal swamp. The objective of the research was to determine the growth response of soybean varieties under saturated soil culture on tidal swamps. The research was conducted at Banyu Urip, Tanjung Lago, Banyuasin District, and South Sumatera Province, Indonesia from April to August 2009. The experiment was arranged in a split plot design with three replications. The main-plot of the experiment was water depth in the furrow consisted of 10, 20, 30, and 40 cm under soil surface (USS). The subplot of the experiments was soybean varieties consisted of Tanggamus, Slamet, Wilis, and Anjasmoro. No-watering was arranged out of the design as a comparison. The result showed that nutrient absorption of N, K and Mn by Tanggamus was higher than those of other varieties, except K, however K absorption of Tanggamus was not significantly different from Anjasmoro. P and Fe absorption of Tangamus tended to be higher than the other varieties, although statistically they were not affected by variety. However, technically and economically, 20 cm USS was the most appropriate water depth for soybean production at tidal swamps.

Abstract

Penelitian bertujuan untuk mendapatkan takaran bokashi jerami terbaik terhadap pertumbuhan dan hasil 5 galur/varietas tomat, untuk mendapatkan galur/varietas tomat yang potensial pada pemakaian bokashi jerami, dan untuk mendapatkan interaksi takaran bokashi jerami dan galur/varietas tomat yang terbaik terhadap pertumbuhan dan hasil. Penelitian dilaksanakan di Kandang Mas Mulya Kota Bengkulu menggunakan Rancangan Acak Kelompok Faktorial 3 ulangan. Faktor pertama takaran bokashi jerami terdiri dari tanpa bokashi jerami; Bokashi jerami 10 ton/ha; 20 ton/ha; dan 30 ton/ha. Faktor kedua Galur/Varietas tomat , yaitu: G5 (LV 3644), G8 (LV 3681), G10 (BPH 1604), G13 ( Lokal), dan G15 (Panah Merah). Data yang diperoleh dianalisis dengan Uji Fisher dilanjutkan dengan uji DMRT 5 %. Takaran bokashi jerami berpengaruh sangat nyata terhadap umur panen, berpengaruh nyata terhadap jumlah tandan buah pertanaman, dan berpengaruh tidak nyata terhadap peubah lainnya. Hasil penelitian menunjukkan tanpa penggunaan bokashi jerami memberikan pertumbuhan dan hasil terbaik bagi galur/varietas tomat. Perlakuan Galur/Varietas berpengaruh sangat nyata terhadap tinggi tanaman umur 4 minggu setelah tanam, jumlah cabang umur 4 minggu setelah tanam, dan umur panen, berpengaruh nyata terhadap jumlah tandan buah pertanaman dan jumlah buah pertanaman, serta berpengaruh tidak nyata terhadap peubah lainnya. Galur/varietas yang potensial adalah G13 (Varietas Lokal) Interaksi Takaran Bokashi Jerami dengan Galur/Varietas berpengaruh sangat nyata terhadap umur panen, dan berpengaruh tidak nyata terhadap peubah lainnya.

Abstract

The experiment was aimed to know the effect of BAP Plant Regulator to the formation and the development of Potato’s Micro Tuber. The treatment were 0; 2,5; 5; 7,5 mg/L BAP. The growing media was Murashige and Skoog (MS0). The result showed that BAP did not significantly affected the number, diameter, wet and dry weight of the tuber. However, the highest of number, diameter, wet and dry weight was found at the 7,5 mg/L BAP. The fastest formation of tuber was yielded in 5 mg/L BAP.

Abstract

The investigation was done to use the allelopathical potency of tested weeds as botanical herbicide, to find the best concentration of weed extract, to find the effect of allelopathy to either weed of onion or the onion. The experiment was carried out in experimental land of Agriculture Faculty, The University of Hazairin, North Bengkulu and Laboratory of Agronomy for four months.The experiment was arranged factorially in a randomized block design with three replications. The kinds of extract weeds were Imperata cylindrica, Cyperus rotundus, Mikania micrantha and Ageratum conyzoides. Concentration was applied at 0%, 10%, 20%, 30%, and 40%.The result concluded that extract, concentration or interaction of the two not only affected insignificant to growth and yield of onion but also dry weight of weed. However, extract of Cyperus rotundus tent to suppress the weed around the onion. Concentration of extract showed inconsistent response to all parameters. It probably because the concentration was still low so that the effect of maintenance was dominant.
