Abstract

The objective of this research was to know influence of interaction between the potassium dosage and soil dampness level, and also influence of potassium dosage and soil dampness level toward sweet corn growth and production. It was conducted from May to July 2006. The result of the research can be summarized as follow: (1) Interaction between potassium  dosage and soil dampness level had  significant effect on cob weight without coat and dry cob weight, and the best combination was 225 KCl/hectare with 85% soil dampness level; (2) Potassium dosage and soil dampness level also had significant effect on cob weight without husk, which was 64,29% higher than those without potassium at similar soil dampness level. This was the result for 225 KCl/hectare and soil dampness of 85%.

Abstract

Very low level of Phosphorus (P) availability in lowland area may cause serious hidrance on soybeanproduction in Riau. Addition of P fertilizer to the soil is significant for accelerating soybean production,however there were very limited farmers which were wiling to fertilize their soybean due to limitedcapital and unavailable cultivars that is efficient in absorbing P from soil particles. Therefore, it isimportant to investigate the efficiency of P fertilizer by soybean cultivars (Glycine nuv: L . Merril).This experiment are intended to identify soybean cultivars that are responsive to P-Fertilizer from dieobservation on the growth and production of soybean and to investigate the efficiency of P-Fertilizerby soybean cultivars. The experiment has been conducted in the Field Station of Faculty of Agricul-ture, Riau University located at Pekanbaru, Riau. The materials consisting of 5 cultivars of soybean, is: Kipas Putih, Malabar, Willis, Argoimtlyo and Bromo. Had been planted in plots applied by fourlevels of P fertilizer. The levels of P fertilizer were 20 kg, 40 kg, 60 kg PO per hectare and control.The experiment were arranged in a randomized factorial block experiment with three replications. Ingeneral, addition of fertillizcrdid not influence crop growth significantly especially on vegetative diyweight, the percentage of filled pods, individual seed weight, and P absorption efficiency.The cultivarsdiffered significantly in response to P fertilizer aplication. Optimum efficiency of seed production wasfound for Kipas Putih and Bromo at the level of 40 Kg PO per hectare while in other cultivars, theoptimal, was reached when they where not fertilized by P fertilizer. Optimum absorption of P fertilizerwere detected on Kipas Putih and Bromo at the level of 40 kg PO, per hectare, while in othercultivars the optimum absorption efficiency was obtained when crops were not fertilized.

Abstract

The study on growth production of paddy (Oryza sativa L.) Variety IR-64 in the peat soil given Dolomite andCopper (Cu) through leaves have been conducted at Simpang Baru Village Tampan, Pekanbaru City for 5bohths; starting from February to June 2003. The objective of the experiment was identity the effect ofbolomite and Copper given trough leaves and their interaction on the growth and pnKiuction of Rice in the peatisoil. The experiment was arranged in a randomized factorial block design with three replications. The firstfactor was various doses of Dolomite, that was KO (without Dolomite), K l (Dolomite of 0,5 ton/ha), K2 (Dolomiteof 1,0 ton/ha), K3 (Dolomite of 1,5 ton/ha), and K4 (Dolomite of 2,0 ton/ha). The second factor was various dosesof CuSO,, that was CO (without CuSO,), C I (CuSO, of 100 g/ha), C2 (CuSO^ of 200 g/Tta), C3 (CuSO, of 300g/lia), and C4 (CuSO, of 400 g/ha). Parameters observed were plant height, weight of drayed straw, number ofproductive samplings, percentage of well filled rice grain, weight of 1000 .seeds, weight of rice grain. Experi-ment result show tlrnt Dolomite could improve the growth and production of paddy rice and Chopper significantlyincreased weight of dried straw, percentage of well filled rice grain, weight of 1000 seeds and weight of ricegrain. The interaction between Dolomite and Copper significantly increased the weight of dried straw. Ricegrain production treated with 1,5 ton/ha Dolomite and CuSO^ 400 g/ha given trough leiives wiis 2,97 ton/ha.

Abstract

This research aimed to know the dose of pota«ium Tertilizer, phnt spacing and sawdust ash toincrease production of ginger and com planted at multiple cropping system. TMs research was conducted byCompletely Randomized Btocii Design (RAK) factorial consisted of 2 facton and 3 replications. The researchstarted on April and fmisbed on Augnst 2<m. The first factor was potaasinm fcrtlizcr with dose ofO kg KCVha, iOO kg KCI/ha, 200 kg KCI/ba, and 300 kg KCI/ha. The second factor was different plant spacmg ofginger crop which were 25 i3S cm, 30140 cm, and 35 x 45 cm. Every treatment and replication was 2 x 2 m.Parameters observed were height of ginger crop and corn crop, relative growth rate of ginger and corn,number of ginger crop, wet weight of ^nger crop, dry weight of ginger crop, the timeflowersappear of corn,dry grain weight of com crop, and weight of 100 com grains. The result of linear analysb of variant wascontinued by Duncan New Multi|rie Range Test (DNMRT) at 5 level Researchrasnhindicated that application%of potassium fertilizer with dose of 100 kg/ha and 25 x 3S cm of ginger crop spacing represented the besttreatmen t to increase production of ginger and application of potassium fertSizer with dose of300 kg/ha and30 X 40 cm, 35 x 45 cm represented (he best treatments to increase production of corn.
