Judul: Efektivitas Paket Pupuk Daun Growmore 12-45-10 Dengan Pupuk Konvensional Terhadap Pertumbuhan, Produksi, Dan Kadar Hara Tanaman Jagung (Zea mays L.) Pada Lahan Latosol Darmaga
Abstrak: The limitation of com comudity in the country has not been enough to fulfill the national needs. The increasing of production com could be made by giving correct fertilizer on time, the amount and the kind of the fertilizer in the application. Beside giving fertilizer through the soil it can be done also through the leaves. Fertilizing through the leaves have strongness point, the dosage will by standard, then the sensivity can be arranged and the accuracy is better, it provides good result in macro and micro, in the amount and limited tirr ' The leaves shell and the root shell, take good result through "apoplast". This research is hoped to observe the effectivity of Growmore leaves 12-45-10 on the dosage of conventional fertilizer is differen. fertilizing by using conventional standard dosage (advice from "Depart, Pertanian") on the increasing of products parameter and the basic plantation c and well as the economic growth. The design of this reserch used is rando mehod (planing random group) 10 treatment and 3 replicates. The result of this research indicates that the application of the Growmore leaves fertilizer 12-45-10 gives positive effect better than standard dosage activities and the control on the growth parameter, product component and basic hara (N, K and Ca). The value of RAE (Relative Agronomic Effectiveness) on the treatment of dosage conventional fertilizer 225 Kg/ha Urea, 100 Kg/ha SP-36, 75 Kg/ha KCL and the dosage of Growmore fertilizer 15 Kg/ha, can reach 173,4% compare with treatment standard. On the analysis at farmer business effort competence by using R/C ratio, the package of Growmore leaves fertilizer 12-45-10 with conventional growth fertilizer the biggest one is on the conventional fertilizer 150 Kg/ha Urea, 50 Kg/ha SP-36, 37,5 Kg/ha KCL and dosage of the Growmore fertilizer 12 Kg/ha, the ratio score is 1,60 and the profit will be taken is about 0,60 times from capital.

Judul: Efektivitas Pupuk Daun Growmore 6-10-40 Terhadap Pertumbuhan, Produksi Dan Kadar Hara Tanaman Jagung (Zea mays. L) Pada Tanah Latosol Darmaga
Abstrak: One of the methods in using fertilizer is the use of fertilizer on the leave, commonly known as a foliar fertilization. Absorption of nutrient elements which is sprayed on the leave is conducted by stomata and cuticle. Foliar fertilization leave is relatively more efficient compared with fertilizing through roots. The nutrient absorption on leaf is faster than those at the roots. So crop growth is better and may reduced soil degradation. The objective of this research was to study the effectiveness of foliar fertilizer of Growmore 6-10-40 on the growth, production and nutrient content of corn plant (Zea Mays L. ) in Latosol Dannaga and economic feasibility. The design of the research was randomized completely block design (RCBD) with one factor and three replication. The factor consists of 10 treatments i.e. 1) control (without fertilizer); 2) SI (200 Kg Urea, 100 Kg SP~36, and 37,5 Kg KCl per hectare) Gl; (3,5 Kg Growmore per hectare); 3) SlG2 (7 Kg Growmore per hectare); 4) SlG3 (10 Kg Growmore per hectare); 5) S1G4 (14 Kg Growmore per hectare); 6) S2 (250 Kg Urea, 150 Kg SP-36, 75 Kg KCI per hectare) Gl; 7) S2G2; 8) S2G3; 9) S2G4; and 10) Standard! Standard Fertilizer's dosage (300 Kg Urea, 200 Kg SP-36, 150 Kg KCI per hectare) The result of this research indicated that generally application of foliar fertilizer of Growmore 6-10-40 significantly increase variables of the nitrogen content of corn leaf, diameter and length of corn, weight of 100 seeds of corn, weight of fresh grain and seed of corn The Highest RAE grade occurred at standard treatment (100 %) while on Growmore 6-10-40 treatment, the highest RAE occurred at S2G4 treatment (97,6%), followed by S1G3 (93,8%), SlG4 (92,68%), S2G2 (82,25%), S2Gl (81,12%), S2G3 (70,14%), S1G1 (67,04%) and SlG2 (66,20%). Based on the economically feasibility using Revenue/Cost Ratio, all of treatments were able to be recommended, except treatment of control. The highest RIC ratio was belonging to S1G3 treatment (1,63). Thereafter, based on the computation of optimwn rate, the optimum rate of Growmore 6-10-40 was 1,95 gil and its equal 6,26 Kg per hectare.
