Abstract

ABSTRACT This research aims to study response of sweet corn plants (Zea mays saccharata L.) that were fertilized with organic fertilizer. The research was implemented in green house of Agriculture Faculty, Sam Ratulangi University of Manado, on July to November 2012. The result of research as follow : Height of plants on D treatment (15 tons of stable fertilizer per hectare + 750 kilograms of granul organic fertilizer per hectare) gave best respons, Number of leaves on C treatment (15 tons of stable fertilizer per hectare + 500 kilograms of granul organic fertilizer per hectare ) and D treatment ( 15 tons of stable fertilizer per hectare + 750 kilograms of granul organic fertilizer per hectare) gave best response. Result of sweet corn that were measured by length, diameter and weight of corn cob on B treatment (anorganic fertilizer of N, P and K with recommended doses N 300 kg per hectare, P 150 per hectare, P 150 kg per hectare, and K 150 kg per hectare) gave best response. Keywords :sweet corn, organic fertilizer

Abstract

ABSTRACTThis research aims to study the response of growth and production paddy rice methods sri (system of rice intensification) toward granting the organic and inorganic fertilizer that implemented in the village of Tara-Tara II, subdistrict tomohon west for 5 months start from march to august 2013. This study uses a randomized block design group (RAK) and the faktor the meticulous is a kind of organic fertilizers combined with the treatment of inorganik fertilizers (NPK) consists above P0 = 100 % NPK, P1 = organic fertilizers market waste + 40% NPK, P2 = organic fertilizers plant calliandra + 40% NPK, P3 = organik fertilizers rice straw + 40% NPK, P4 = organic fertilizers mixture + 40% NPK.awarding Organic and inorganic fertilizer give influence the growth and production paddy rice methods SRI (System of Rice Intensification). treatment p3 is the best results high toward rice plants with a value of 96.7, but not significantly different with treatment P1, P2, and P4. the influence most well toward the number of produktive tillers and the persentage of grain pithy/ panicles by value 96,58%. Treatment p3 derive the best results in a variable number of grain / panicle with a value of 234.0, but not significantly different with treatment P1 and P2. treatment P4 is the best result toward weight 1000 grain of dry grain harvest with a value of 28.24 grams, although not significantly different with treatment P1, P2, and P3. on variables outcome dry grain harvest the / plot, the best result is the treatment P3 with a value of 8.0 kg, although not significantly different from P2 treatment.keywords: Paddy rice, SRI (System of Rice Intensification), organic fertilizers and inorganic fertilizers.

Abstract

ABSTRACT This research aims to study the application of Rice Straw Compost on Growth and Production of Sweet Corn ( Zea mays saccharata Sturt ) This study was conducted in the village of Tomohon sub district Taratara Dua West , Tomohon for 3 ( three ) months starting from the month of August to October  2014.  Experimentalwas design arranged in a Randomized Block Design (RBD), consisted of five treatments.It is treatment wasreplicated three times. The treatments waswhitout rice straw compost (K0), 5 ton/ha of rice straw compost (K1), 10 ton/ha of rice straw compost (K2), 15 ton/ha of rice straw compost (K3), and 20 ton/ha of rice straw compost (K4). Data was analysed using variance analysed Least Significant Difference ( LSD ) at level 5%. Results slowed that the treatment significantly effected on growth and production of sweet corn  ( Zea mays saccharata Sturt ) that were plant height, number of leaves , cob length, cobweight, but not significant to cob circle  effect  Keywords : Sweet Corn, Organic fertilizer
