    The assesment was conducted at Tandun, Tokan Hulu district in MT 2010. The study was designed with a randomized block design with two factors, three replications. The first factor is the time of planting soybean after rice planting of: (1) two days after the rice harvest, (2) 5 days after the rice harvest, (3) 8 days after the rice harvest, and (11) 11 days after the rice harvest. The second factor is rice straw mulch (a) 2 t / ha, (b) 4 t / ha, and (c) 6 t / ha. From the results showed planting date affect growth and yield of soybean. Planting at 2 days after harvest rice crop gives the best results to the number of branches, pods / plant and the results compared with other treatments. Straw mulching also significantly affect plant height, number of pods / plant and yield. Rice straw mulching with a dose of 6 t / ha gave the highest yield compared to the other dose. The interaction between soybean after rice planting mulching also significantly influenced the growth, yield components and yield of soybean. Combination treatment between planting two days after the rice harvest by mulching with a dose of 6 t / ha gave the highest yields

    KAJIAN PEMUPUKAN P, RESIDU PEMUPUKAN P DAN PUPUK KANDANG TANAMAN PADI TERHADAP PERTUMBUHAN DAN HASIL KEDELAI DI PROPINSI RIAU

    Assessment of P fertilizer, P fertilizer residues and manure on the growth of rice and soybean yields in the province of Riau conducted in Tandun Riau Rokan Hulu, MT 2010. This Assessment wasdesigned 2-factor randomized block design with three replications. The first factor is the residual fertilizer P, K and manure in rice plants which include: (A) 200 kg urea / ha 100 kg SP- 36/ha 100 kg KCl / ha. (B) 200 kg urea / ha 75 kg SP-36/ha 100 kg KCl / ha and manure 2 t / ha (C) 200 kg urea / ha 25 kg SP-36/ha 100 kg KCl / ha, and (D) 200 kg urea / ha 0 kg SP-36/ha 100 kg KCl / ha and manure 2 t / ha. Factor II is the P fertilization on soybean include (a) without P fertilizer and (b) 75 kg SP-36 / ha. The results of the assesment showed the residual of sice fertilizer gave a significant effect on the growth and yield of soybean. Residues of rice fertilization treatment B gave the highest yield of soybean, while treatment D gave the lowest yield of soybean. P fertilization significantly influenced the growth and yield of soybean. P fertilizer application by 75 kg / ha gave better growth than without fertilizer P. So is the residual effect of fertilizer in rice and fertilizer P on soybean significant influence on the growth and yield of soybean. Combination treatment. B with b treatment gave the highest soybean yield.

    This assesment conducted planting systems and rice straw mulch on the growth and yield of soybean in upland province of Riau. Assesment conducted in dryland Tandun, Rokan Hulu districts with slope 9% in MT 2010. The assesment was designed with a randomized block design with two factors with three replications. The first factor is soybean planting systems which include: (A) 10 cm spacing in rows parallel to the contour, and 40 cm between rows. (B) in rows 20 cm spacing of parallel contours, and 40 cm between rows and (C) the way farmers (spacing of 20 cm x 40 cm). The second factor is the provision of rice straw mulch with a dose of: (a) without mulch (b) 2 t/ha (c) 4 t/ha, and (d) 6 t/ha. Observations included the growth and yield of soybean. The results of the study showed significant cropping system on growth, and yield of soybean. Planting system of A gives the best results. Mulching effect on the growth and yield of soybean. Planting and mulching system significantly affect the growth and yield of soybean. Planting system of A combination with mulching with a dose of 6 t/ha gave the best results
