The objective of this study is to determine the effect of rice varieties and different organic matter ofrice fields in one growing season to the 1000 grain weight and paddy rice biomass IP 400. Theresearch was conducted at paddy fields located at UPT Main Rice Seed Big of Pasar MiringTanjung Morawa Subdistrict, Deli Serdang District. This study uses a randomized block design(RBD) with two factors, namely rice varieties Inpari I and Ciherang and organic matter. Eachtreatment consisted of non-organic material, composted straw, cow manure.The results showed thatthe use of varieties of very significant effect on the dry weight of 1000 grain rice planting season IP400 I, and the very significant effect on rice biomass IP 400. Treatment of organic material verysignificant effect on the dry weight of 1000 grain rice IP 400 in the first growing season, and a verysignificant effect terhdap rice biomass IP 400. Interaction between rice varieties and application oforganic manures no significant effect on the dry weight of 1000 grains and rice biomasaa IP 400.Keywords: IP 400, 1000 grain weight, biomass rice

The influence of some botanical pesticides for handling grayak caterpillarSpodoptera litura F.(Lepidoptera: Noctuidae) on Deli tobacco. Grayak caterpillar (a kind ofcutworm) is one of an important pest in Deli Tobacco plant which can reduce production. Thepurpose of the research was to know the effectiveness of gadung storage root, babadotan, and castoroil stones with correct dosage in handling grayak caterpillar (S. litura) on Deli tobacco plants. Theresearch was conducted at Institute of Deli Tobacco PTPN II Sampali Medan, from November,2011 until January, 2012. The research used Randomized Block Design (RBD) design of non-factorwhich comprised ten treatments with three control repetitions: the solution of castor oil stones (40,80, and 120 g/l of water), the solution of babadotan (40, 80, and 120 g/l of water), and the solutionof gadung storage root (40, 80, and 120 g/l of water). The result of the research showed that thetreatment of the solution of gadung storage root with the dosage of 120g/l of water was the mosteffective with the lowest percentage of damage intencity (30.00%), the highest percentage of larvamortality (88.33%), and the highest percentage of plant production (11.22g/plot). The ineffectivetreatment was the control treatment with the highest percentage of damage intencity (49.00%), thelowest percentage of larva mortality (1.79%), and the lowest percentage of plant production(4.53g/plot).Keywords: Deli tobacco, botanical pesticides, Spodoptera litura

The effectivity of some entomopathogenic imago cocoa fruit borerConopomorpha cramerella Snellen (Lepidoptera: Gracillariidae) in the Laboratory. Theobjective of this research was to evaluate the effectifity of entomophatogen (B. bassiana,M. anisopliae and P. fumosoroseus) with different concentration level. The experiment wasconducted at the Laboratory Plant Pests, Faculty of Agriculture, University of Sumatra utara,Medan. From August to October 2012, using a completely randomized design (RAL) nonfactorial of 7 treatments and 3 replications. The treatments were L0 (control),L1 (M. anisopliae 40gr/1l), L2 (M. anisopliae 50gr/1l), L3 (B. bassiana 40gr/1l),L4 (B. bassiana 50gr/1l), L5 (P. fumosoroseus 40gr/1l), and L6 (P. fumosoroseus 50gr/1l).The results showed that 50gr/1l M. anisopliae is effective to control imago C. cramerella(100%), followed by treatments B. bassiana 50gr/1l, M. anisopliae 40gr/1l, andP. fumosoroseus 50gr/1l, the high number of imago C. cramerella overgrownentomopathogenic fungus colony found in 50gr/1l M. anisopliae (60%), followed bytreatments of P. fumosoroseus 50gr/1l, M. anisopliae 40gr/1l, B. bassiana 50gr/1l,B. bassiana 40gr/1l, while P. fumosoroseus 40gr/1l is less effective, and the behavior of deathimago C. cramerella entomopathogenic fungus infected seen with characteristic imago beinglazy move, the longer the body becoming limp and dead, and that eventually hardenedmycelium covered by different colors namely M. anisopliae has green colour, B. bassiana haswhite colour, P. fumosoroseus has yellowish white colour.Keywords : entomopathogenic, cocoa, Conopomorpha cramerella
