Abstract

Yielding variety is one of the important component technologies to increase production. Selection of varieties is suitable with a very supportive environment agro-ecosystem rice farming success. This research aims to determine the proper performance of growth and production of new superior varieties of lowland rice. The experiment was conducted at the farmers’ rice field Sikabau, Pulau Punjung, Dharmasraya Regency, from June to October 2012, using a randomized block design (RBD) with five replications. Treatment used three new varieties of lowland rice, i.e., Logawa, Tukad Unda, Mekongga and the high-yielding varieties of lowland rice of IR 66 which has evolved a long enough as a comparison. The seedlings was planted 3-5 seedlings/hill with spacing of 25 x 25 cm. Fertilizers applied is 300 kg Ponska, 100 kg urea and 30 kg KCl/ha. Data were collected consisted of plant height, maximum number of tiller/hill, number of productive tiller/hill, yield components and yield. The results showed that three new varieties of lowland rice, namely Logawa, Mekongga and Tukad Unda had good growth and yield. The new varieties which had a very good response were Logawa (5.8 t/ha), Mekongga (5.6 t/ha) and Tukad Unda (5.5 t/ha).

Abstract

The use of fertilizers with the right amount could increase the growth and yield of lowland rice. This research aims to determine the effect of fertilizer use on the growth and yield of lowland rice. The experiment was conducted on the farmers field in Sungai Lareh, Koto Tangah District, Padang City of West Sumatera Province, from July to December 2009. Research used Randomized Completely Block Design (RCBD) with five replications. The treatments tested were: (A) Urea + KCl, (B) Urea + SP36, (C) Urea + SP36 + KCl, (D) without fertilizers (as control). The dosages of fertilizer were: 150 kg Urea, 100 kg SP36, and 75 kg KCl per hectare. The results showed that the use of a complete fertilizer (Urea + SP36 + KCl), or combination of Urea + KCl, or combination of Urea + SP36 had a significant effect on the growth and yield compared to without fertilizer treatment. The use of Urea + KCl resulted about 5.04 t/ha dry grains harvest (DGH) or increased grain yield as much as 14.03%, and the use of Urea + SP36 gave the results as much as 5.69 t/ha DGH or increased grain yields as much as 28.73%, and use of a complete fertilizer Urea + SP36 + KCl gave the results 6.13 t/ha DGH or increased yields about 38.69%. Whereas, without fertilized gave only grain yield as much as 4.42 t/ha DGH.

Abstract

Seedling age on the transplanting system is one of the factors that affect productivity of rice crop. This research attempted to determine the effect of seedling age of rice production for obtain the optimal yield. The experiment was conducted on farmer’s rice field in Lubuk Minturun Sungai Lareh village, Koto Tangah district, Padang city, West Sumatra Province, from September 2009 to January 2010. Randomized Block Design (RBD) with four replications and six treatments was used. The treatments were seedling age, namely A (10 days after sowing), B (15 days after sowing), C (20 days after sowing), D (25 days after sowing), E (30 days after sowing) , and F (35 days after sowing). The seedlings used were Batang Lembang variety which was planted on 4 x 5 m plots with a spacing of 25 x 25 cm and three seedlings per hill. Fertilizers used are 150 kg Urea, 100 kg SP36, and 75 kg/ha KCl and were given at 7, 28, and 45 days after planting (DAP ), while the SP36 was given entirely at DAP 7 together with giving Urea and KCl. The parameter measured included plant height, maximum number of tiller/hill, number of productive tiller/hill, yield components, and yield. The results showed that the seedling age affected significantly (P < 0.05) plant height, maximum number of tillers, yield components and yield. The treatment of 20 days on after sowing showed the highest yield components and grain yield, while the treatment seedlings of 35 days after sowing was lowest grain yield. The results suggest that the optimal yield of rice in transplanting system will be obtained by using the 20-day old seedlings.
