Abstract

One of maintain self-sufficiency is programs realized through the implementation of field school of integrated crops management (SLPTT) target increased quality rice with rice cultivation techniques, increased cropping intensity and productivity of rice. This research was conducted at SLPTT locations of Pesawaran regency (4 district), Lampung Province, from May until September 2010. The number of observed samples consisting of 180 units such as LL VUB (Field Laboratory of New Superior Variety) location is 60 units, LL non VUB location is 60 units and non SLPTT location is 60 units. The treatment applied SLPTT LL VUB is PTT (ICM) model such as superior verieties (Inpari 1, Inpari 7, Inpari 9 and Cigeulis), jajar legowo planting system (2:1 and 3:1), and site-specific fertilizer recommendation (Ministry Agriculture recommendation), and application pattern field school (PFS). At the SLPTT LL non VUB location, treatment applied was Ciherang variety and fertilizer dose of local farmers (specific location), while non SLPTT location adapted to the habits of farmers. Data collected were production cost, yield components, and farming system problems. The results showed that the average productivity of paddy at the SLPTT LL VUB location is 7.174 kg/ha, SLPTT non VUB 6.737 kg/ha and non SLPTT 4.587 kg/ha. Use of new superior varieties (VUB) increased productivity by 8,85% compared with SLPTT non VUB and 47,13% compared with non SLPTT. Farmer income in SLPTT LL VUB locations is Rp.17.410.000,-/ha (R/C=3,15), SLPTT LL non VUB location Rp.13.488.806,-/ha (R/C=2,46) and non SLPTT location Rp.9.885.625,-/ha (R/C=2,34).

Abstract

Organonitrofos is one type of organic fertilizer capable of providing macro nutrients that more than other organic fertilizers, particularly nitrogen and phosphorous from the compost of a mixture of fresh manure and rock phosphate using Microbial N2-fixer and P-solubilizer. Research purpose was to study the effect of organonitrophos combined with inorganic fertilizer on the growth, production, yield of sugarcane, and determining the most effective combination of agronomically and economically in up landsugarcane. Research consisted of 5 treatments with 3 replications arranged in a randomized complete block design. The treatment were A (300 kg ha-1 Urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl), B (300 kg ha-1 Urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl, 5,000 kg ha-1 Organonitrophos), C (150 kg ha-1 Urea, 75 kg ha-1 TSP, 150 kg ha-1 KCl, 10,000 kg ha-1 Organonitrophos), D (10,000 kg ha-1 Organonitrophos), and E (without fertilization). The results showed that the dose of fertilizer recommendation (300 kg ha-1 urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl) supplemented with 5 ton ha-1 Organonitrofos compared to the doses of fertilizer recommendation (300 kg ha-1 Urea, 150 TSP kg ha-1, 300 kg ha-1 KCl) was not significantly different on growth, yield, productivity of sugarcane and sugar. While the addition of 10 ton ha-1 Organonitrofos at half dose of recommendation (150 kg ha-1 urea, 75 kg ha-1 TSP, and 150 kg ha-1 KCl) produced 106.11 tons ha-1of sugarcane and 7, 95 ton ha-1sugar being lower than the dose of fertilizer recommendation that produced 133.02 tons ha-1sugarcane and 10.72 ton ha-1 sugar resulting macro nutrients derived from half dose of fertilizer recommendation are not able to increase the productivity of sugarcane and sugar.Dose of fertilizer recommendation plus 5 ton ha-1 Organonitrofos was an effective dose of fertilizer agronomically while fertilizer dosage recommendation was the most efficient dose of fertilizer economically.Keywords :dry land, fertilizer, inorganic, Organonitrophos, sugar cane

Abstract

Oil palm (Elaeis guineensis Jacq.) is one of the important excellent crop plantations which have significance for the development of national farm and country source of foreign exchange earnings.Oil palm cultivation is mostly done on the ground of ultisol that have constraints phosphorus deficiency that needed improvement in the quality of the nursery with the utilization of arbuscular mycorrhiza fungi (AMF). The study aimed: (1) determine the best type of AMF in enhancing the growth of oil palm seedlings, (2) determine dose of NPK fertilize most appropriate for the oil palm seedling, (3) determine whether the response of oil palm seedlings to type AMF influenced by dose NPK fertilizer, and (4)determine the best dose of NPK fertilizer for each type of AMF. The treatment design is a factorial (6x2) arranged in randomize completely block design with 5 replications. The first factor is the type of AMF, design as without AMF, Glomus sp. Isolate MV 23, Glomus sp. Isolate MV 26, Entrophospora sp. Isolate MV 22, Entrophospora sp. Isolate MV 25, Entrophospora sp. Isolate MV 28.The second factor is number of NPK fertilize design as p1 (100 % from recomendation) and p2 (50 % from recomendation). Means homogeneity among the treatments were tested using Barlett test and the aditivity data were tested with Tukey test. Separation of means value were analyzed using Least Significant Difference (LSD) at 5% significance level. The results showed the interaction between the type and dose of NPK fertilizer AMF is can be concluded that (1) oil palm seedlings response to AMF inoculation type is determined by the dose of NPK fertilizer on the variable plant height, dry weight of root, and number of primary roots, 2) the optimum dose for each type of AMF are used based on the data root dry weight is a combination of 100% NPK fertilizer with each type of AMF, excepton the AMF types Entrophospora sp.

Abstract

Soybean is one of the crops that produce seeds with high protein content, as well as used by the inhabitants of Indonesia. Domestic soybean production can not meet the needs of the national soybean thus needs to be improved, one through breeding varieties with superior. One important step in plant breeding is the selection. To save time and costs of selection, it is necessary to determine the estimated correlation between characters  and to determine the causal relationship between characters used path analysis. Through path analysis can be seen directly and indirectly influence between variables forecaster with the response variable. The purpose of this study to obtain information (1) correlation between characters agronomic towards production. (2) direct and indirect effects of agronomic between characters towards production. The research was conducted from October 2013 until January 2014 in the integrated field laboratory of the Faculty of Agriculture, University of Lampung and observations made in Laboratory of Seed and Plant Breeding, University of Lampung. Soybean seeds used were  F5 generation zuriat from Wilis x Mlg 2521,  Willis and Mlg 2521. The treatment laid out in a randomized block design,  2 replications. The results showed that  there was a positive phenotype correlation between character of days to flowering, plant height, number of branches, number of pods, weight of 100 grains with grain weight per plant and there was no correlation between day to harvesting with the seed weight per plant. Direct selection of the most effective  was through the number of pods because number of  pods have a direct effect almost equivalent to the correlation. The relationship between the number of pods  and weight of seeds per plant explained a real relationship. Keywords: correlation, path analysis, selection, soybean
