This research is proposed to find out the response of growth and yield of paddy rice situ bagendit variety by tillage of land ground and frequency of weeding. It was conducted at Dinas Pertanian UPT BBI, Tanjung Selamat with a height of 57 m above sea level on March until June 2012 with the soil which has ever tillage before, by using a Randomized Block Design of two factors, they are tillage of land ground (no tillage, two tillage and three tillage) and frequency of weeding (weeding 7 day, 14 day, 21 day and weeding full). The parameters observed were plant’s height, numbers of tiller, numbers of panicle, percentage shell of empty rice, number shell of rice containt, production shell of rice contain, 1000 grain weight, production shell of plot weight dry root and weight dry paddy stem. The results showed that tillage of land ground and frequency of weeding showed significant effects on plant’s height of 6 MST, numbers of tiller of 4 MST, numbers of tiller of 8 MST, percentage shell of empty rice, weight dry root and weight dry paddy stem.

This research aims to test the response of seedling growth of cocoa (Theobroma cacao L) againstNPKMg fertilizer (15: 15: 6: 4) and the filter cake compost on soil media subsoild Ultisol. Thisresearch using randomized block design (RBD) factorial with 2 (two) treatment factors. The firsttreatment is: Compost filter cake with 4 level: M0 = subsoil Ultisol + compost filter cake (5kg+ 0 kg), M1 = subsoil Ultisol + compost filter cake (3.75 kg + 1.25 kg), M2 = subsoil Ultisol +compost filter cake (2.5 kg + 2.5 kg) , M3 = subsoil Ultisol + compost filter cake (1.25 kg+ 3.75 kg). The second factor, namely: Fertilizer dose NPKMg follows: P0 = 0 g / polybag,P1 = 3 g / polybag, P2 = 6 g / polybag and P3 = 9 g / polybag. Parameters measured wereseedling height, stem diameter, number of leaves, total leaf area, canopy wet weight, dry weightcrown, root wet weight and dry weight of roots. The result showed that the treatment effect is notreal compost filter cake growth of cocoa seedlings.

Coconut water is good in increasing the plant’s growth because it containsfitohormon and several growth vitamins. The right dosage of NPKMg fertilizationcan maximize the growth of cacao seedling. This research was conducted in desaTanjung Selamat kecamatan Medan Sunggal, start on January 2012 and end onMay 2012. The design used was a factorial randomized block design with twotreatment factors. The first factor is the duration of soaking in coconut water in 4stages, which are K0 (0 hour), K1 (6 hours), K2 (12 hours), dan K3 (18 hours).The second factor are the application of NPKMg fertilizer (15:15:6:4) in 4 stages:which are: P0 (0 g), P1 (7 g), P2 (14 g), P3 (21 g). The soaking of cocoa seeds incoconut water has significant effect on plant height and number of leaves.Interaction between soaking of cocoa seeds in coconut water and NPKMgfertilizer application has no significant effect on all parameters.Key words : coconut water, NPKMg fertilizer, cocoa, growth and production

ABSTRACTGrowth of Cocoa Seedlings (Theobroma cacao.L) In Media Ultisol Subsoil with FertilizerProvision NPKMg(15:15:6:4) and Manure. This research aims to determine the effect of manureand fertilizier NPKMg(15:15:6:4) on the growth of cocoa (Theobroma cacao.L) in media landultisol subsoil. Research carried out in field trials USU Faculty of Agriculture, Medan with altitudeof about 25 meters above sea level at the beginning of November until March 2012. Experimentalmethod use is a randomized block design with two treatment factor. Planting media as the firstfactor with five standard treatment that is 0% Manure + 100% Ultisol Subsoil, 25% Manure + 75%Ultisol Subsoil, 50% Manure + 50% Ultisol Subsoil, 75% Manure + 25% Ultisol Subsoil, 100%Manure + 0% Ultisol Subsoil and fertilizer NPKMg(15:15:6:4) as the second factor with four levelis 0 g/polibag, 4 g/polibag, 8 g/polibag and 12 g/polibag with 3 replications. Parameter wereobserved at high parameters of shoots, girth, number of leaves, the aweight of wet canopy, wetweight of roots, canopy dry weight, and root dry weight. The results that 75% Manure + 25%Ultisol Subsoil showed the best results at high parameters of shoots, girth, number of leaves, theaweight of wet canopy, wet weight of roots, canopy dry weight, and root dry weight. NPKMgfertilizier(15:15:6:4) in this study showed significant results in all parameters, but obtained at thehighest treatment level 8 g/polibag and 12 g/polibag. The interaction effect was not significanteffect on all parameters.Keywords: manure, NPKMg fertilizer, Theobroma cacao.L .poultry manure

Research on title the growth and yield of shallot on different soil tillage and giving NPK fertilizerthis research was to determine growth and yield of Shallot on different soil tillage and Giving NPKfertilizer. This research had been conducted at Farm Resident on street Pasar I number 89, TanjungSari, Medan at ± 25 m asl from May until July 2013 using split plot design with two factor, i.e. SoilTillage (once tillage and twice tillage) and dose of NPK fertilizer (0; 0,6; 1,2; 1,8 and 2,4 g/ plant).Parameter observed were plant height, tillers number per sample, leaves number per sample, clovenumber per sample, wet weight tuber per sample, wet weight tuber per plot, dry weight tuber persample, dry weight tuber per plot and dry weight root per sample. The result showed different soiltillage treatment significantly affected on wet weight tuber per sample and dry weight tuber persample. NPK fertilizer treatment significantly effected on parameters plant height, wet weighttuber per sample, wet weight tuber per plot, dry weight tuber per sample and dry weight tuber perplot. The interaction of two factor not significantly affected all of parameter observed.Keywords : Soil Tillage, NPK Fertilizer, Shallot
