The effect ot the type of herbicide to controlling weeds and the increasing thegrowth and yield of rice plants in tabelaltot planting system. Rice plants are the most important crop cultivation because most of the population makes rice as a staple food. Efforts to support the fulfillment of rice needsare made by maintaining rice productivity. Increased rice productivity is currently stillexperiencing obstacles such as in improper crop cultivation techniques and problemsin weed control, therefore proper weed cultivation and control techniques need to beassessed. The purpose of this research was to find out the type of herbicide that is mosteffective in controlling weeds and can increase the growth and yield of rice plants intabelaltot planting system. This study used a randomized block design (RCBD) with4 treatments, namely control (without herbicide treatment), logran herbicide,metafuron herbicide and benfuron herbicide. The treatment was repeated six times.The results showed that the herbicide treatment significantly affected the weight of thedried grain harvest compared with control. Logran herbicide treatment showed thehighest dry grain weight of ha-1 harvest was 8.38 tons / ha-1 and significantly differentfrom the control of 6.00 tons / ha-1, the high yield was due to the ability of logranherbicide that could suppress growth of the highest weeds, namely 77% compared toherbicides metafuron namely 57% and benfuron namely 56% and significantlydifferent compared to controls, the competition that occurred between rice plants andweeds in logran herbicide treatment was less so that it made yields increase.

Effectiveness of Giving Some Herbicides on Weed Growth and Yield of Rice Plants with Direct Seed Sowing System without Ground (TABELATOT) One of the obstacles in rice cultivation is the presence of weeds. Weeds are plants that humans does not want in the located that can reduce agricultural yields. Weed control techniques in rice plants can be done by using herbicides. This study aims to determine the types of weeds that grow in rice cultivation with the tabelatot system for each type of herbicide used, to determine the effectiveness of each type of herbicide used on weed growth and lowland rice yield in the tabelatot system, to determine the type of herbicide. which one can increase the growth and yield of rice in a tabelatot planting system. This study used a randomized block design (RBD) with 4 treatments, namely control, logran herbicide, metafuron herbicide and benfuron herbicide. This treatment repeat six times. Based on the statistical results, it was found that the types of weeds that grew in rice cultivation were 2 (two) from grass groups, namely Echinochloa crusgalli (L.) Beauv, and Cynodon dactylon, 1 (one) from the nut group namely Cyperus difformis L, and 4 ( four) from broadleaf groups, among others, Monochria vaginalis (Burm.f.), Ludwigia octovalvis, Spenochlea zeylanica, and Limnocharis flava. The results showed that the herbicide treatment logran, metafuron and benfuron could reduce the weight of wet weeds m-2 at the age of 42 hss, 0.90 kg and 0.92 kg, respectively or decreased by 86%, 57% and 56% compared to the control, namely 2.13 kg and reduced the weight of oven dry weeds as much as 0.01 kg, 0.09 kg and 0.09 kg, respectively or decreased by 95%, 59%, and 59% compared with 0.22 kg without herbicide. he most effective herbicide in controlling weeds in the table cropping system is logran herbicide seen from the parameters of oven dry grain weight ha-1 (ton), the treatment of logran herbicides, metafuron and benfuron can produce weight of 5.31 tons, 5.28 tons respectively. and 5.25 tons or increased significantly by 65%, 64% and 63% compared to the control, namely 3.23 tonnes, the high yield was due to the ability of logran herbicides to suppress weed growth so as to minimize competition between rice and weeds.

This study was conducted in Balai Benih Induk (BBI) Luwus, Baturiti District, Tabanan Regency, with the high of place 506m above sea level occurring in March to May 2014. This research used randomized block design arranged per factor, namely population of plants (P) including three steps: P1=80.000 plants per hectare, P2= 100.00 plants per hectare, P3= 120.000 per hectare; and mulch (M) that include: M0= without mulch and without cleaning, M1= without mulch with clean weeding, M2= rice plants straw mulch (5 ton per hectare) and M3= black silver plastic mulch. Eventually, there were 12 combination treatments, each of which was repeated 3 times to obtain 36 land slots. The research indicates that there was no real interaction between the treatment of plant population and mulch usage in all variables observed. The 100.000 plant population per hectare can produce the weight of dry and fresh oven corn kernel without highest cornhusk that was to say 4.79 tons and 0.53 tons or 11.66 % and 20.45% higher compared to 120.000 plant population per hectare. The use of black silver plastic and rice plants straw mulch can produce the weight of fresh and dry oven corn kernel without cornhusk per hectare each of which is 4.69 tons, 4.57 tons, and 0.54 tons, 0.47 tons or 26.76%, 38.46 %, and 23.51 %, 20.51 % higher than without mulch and without clean weeding. Clean weeding treatment can produce the weight of fresh and dry oven corn kernel without cornhusk per hectare with its weight of 4.63 tons and 0.51 tons or 25.35 % and 35.90 % higher than without mulch and cleaning. Clean weeding treatment was not obviously different from mulch treatment. The identification of weed types were 19 kinds of weeds and Cyperus rotundus L. Weeds. They have the highest density and each absolute frequent of 1249.333 stems m-2 and 1.00.
