A reaserch concerning effectivity ofarbuscular mycorrhizal applied on setaria (Setaria sphacelata) grass was conducted at Field Laboratory Peternakan (LLP) located on Utama Street Gampong Rukoh andat Nutritional Science dan Feed Technology Laboratory,Department of Animal Husbandry Faculty of Agriculture, Syiah Kuala University from February to April 2017. The objective of this research was to find setaria grass performance applied with arbuscular mycorrhizal. Completely Randomized Design was used in this research with 4 treatments (L0 = control/0 gr arbuscular mycorrhizal applied per clumps, L1 = 5 gr arbuscular mycorrhizal applied per clumps, L2 = 10 gr arbuscular mycorrhizal applied per clumps, and L3 = 15 gr arbuscular mycorrhizal applied per clumps. Plant height, leaf width, number of tillers, fresh root weight and dry root weight were the parameter determined. The statistical analisisindicated that there was no significant effect (P0.05) caused by treatments on plant height, leaf width, number of tillers, fresh root weight and dry rootweight. The results revealed that all level of arbuscular mycorrhizal applied showed no effectiveness on setaria grass performance. Abstract.

Katuk {Sauropus androgynus (L.) Merr} is a leafy vegetable which requires nitrogen for itsvegetative growth.  This study was aimed at assessing the agronomic performance of various accessions of katuk vegetable grown with different rates of urea fertilizer administration.  A completely randomized design with two factors was used.  The first factor was katuk accessions consisting of Sukaraja Sukabumi, Cugenang Cianjur, and Kemang Bogor.  The second factor was urea fertilizer administration in five rates, namely 0, 33.3, 66.7, 100%, and 133.3% of recommended rate (R).  Results showed that katuk plant of Sukabumi accession gave the best plant height and leaflet area.  Katuk plant of Cianjur accession had the highest values of plant height, number of buds, yield fresh weight, yield dry weight, and root length.  Katuk plant of Bogor accession was found to have the highest fresh root weight.  Urea administration of 66.7-133.3% R resulted in katuk plant with the best values of plant height, number of buds, stem diameter.  The widest leaf area was found in 100% R urea administration and the highest root weight was found in plants treated with 66.7% R urea administration.  The increase of urea fertilizer doses starting from 33.3% R in Cianjur and Bogor katuk accession increased the total harvest wet weight and dry weight, while in Sukabumi accession the significant increase in production was at a dose of 100% R and 133.3% R urea. The increase in vitamin C content was significant in the application of 133.3% R urea fertilizer.

Abstract This study aims to determine the mineral content of cuscus’ manure and its utilization on the growth of Setaria spachelata grass. The study was designed with a completely randomized design (CRD) with 3 treatments (control / P0; cuscus manure from banana fruit feed / P1; and cuscus manure from avocado / P2) and 5 replications. The dose of organic fecal fertilizer for cuscus, 40 grams / polybag. The setaria seedlings used were adult poles measuring 20 cm, which were planted in polybags measuring 30 x 15 cm and weighing 5 kg of soil. The results showed that there were differences content in manure mineral among the types of fruit eaten as feed. Furthermore, its use on setaria grass was able to increase its growth, namely plant height, number of leaves and number of tillers, the control treatment was significantly different from treatment P1 and P2 (P <0.05), but between P1 and P2 did not show any differences. Plant height ranges from 35.10-39.10 cm, the number of leaves is 71-101, while the number of tillers is 13-21 tillers per polybag. The cuscus manure has the potential as organic fertilizer.

AbstractThis study aimed at determining shoot and root characteristics of cassava as affected by root yield and the influence of soil moisture on vegetative growth and yield. Thirty cassava genotypes were evaluated for morphological and physiological characterization in three locations in Nigeria: Ibadan, Mokwa and Zaria. Randomized complete block design was used with four replicates. Studies on the pasting properties of the genotypes were also carried out. Data were collected on plant height, stem girth, stay-green ability, garri and fresh root weight. Genotypes differed significantly (P < 0.05) across and within locations for shoot and root characteristics. Across locations, genotype 011663 had the highest plant height (132.4 cm); 30572 had the largest stem girth (8.6 cm); and 010040 was the best stay-green (2.2). Genotype 011086 had the highest number of roots per plot (95.7), 950289 had the highest fresh root yield (24.3 t/ha), and 990554 had the highest percentage of dry matter (35.2). Trends in root yields across locations were Ibadan (28.9 t/ha), Mokwa (20.3 t/ha), and Zaria (8 t/ha). Five genotypes IITA-TMS-IBA950289, 010034, 990554, 011807, and 980581 had negligible interactions with the environment and so have broad adaptation and are considered stable; and two clones 011807 and 950166 were found to be the best for pasting properties. Breeding strategies that consider root size, total root number, harvest index, dry matter, with applications for household foods and industrial uses, will be an effective and efficient way to select genotypes for high yield.

This study aimed to determine the best dosage of goat manure as a natural fertilizer on Beha grass(Brachiaria humidicola). This study used 64 poles of Beha grass grown in polybags divided into 16plots, and it used a completely randomized design (CRD) to analyze the data. This study consist of 4treatments that is P0 (0 ton/ha of goat manure), P1 (10 ton/ha of goat manure), P2 (15 ton/ha of goatmanure), and P3 (20 ton/ha of goat manure). This study's variables were plant height, number of leaves,numbers of tillers, new production, and root length. Data analysis used ANOVA variance continued withreal honest difference test. The result of this study showed that averages of plant height (cm) wereP0=26, P1=50.5, P2=51.5, and P3=52.75. Averages of the number of leaves were P0=22, P1=110,P2=160, and P3=185. Averages of numbers of tillers were P0=7, P1=25, P2=37, and P3=38. Averages ofnew production (g) were P0=17.75, P1=123.5, P2=178, and P3=192.25. Averages of root length (cm)were P0=37.8, P1=39.5, P2=41.775, and P3=49.5. Fertilization with natural fertilizer from goat manurehas a genuine effect (P<0.01) on the growth of Beha grass. The best dosage of fertilization with goatmanure was 15 ton/ha.

Sugarcane (Saccharum spp. hybrids) is moderately sensitive to salinity and the effects on plant performance vary according to stress level and genotype. This study aimed to evaluate the effect of salt stress induced by application of different NaCl levels in the irrigation solution on plant height, indirect index of chlorophylls (SPAD), and macronutrients concentration (N, P, K, Ca, Mg and S) and Na in leaves of two sugarcane varieties: CP 72-2086 and Mex 69-290. The experiment was set in a completely randomized design with a 2×5 factorial arrangement. The study factors were sugarcane variety (CP 72-2086 and Mex 69-290) and NaCl concentration (0.0, 71.8, 143.6, 215.4 and  282.7 mM NaCl). Salinity as a single factor negatively affected plant height, SPAD units and N and P concentration in leaves; Ca concentrations increased, while K, Mg and S remained unaffected by the tested NaCl levels. Mex 69-290 grew higher and concentrated greater levels of N and K. Interactions of factors showed that salinity reduced growth in both varieties, but this reduction was more pronounced in CP 72-2086. SPAD units were also significantly reduced by salinity in both varieties. Concentrations of N and P in leaves decreased in both varieties in response to NaCl, while those of K and Ca increased in Mex 69-290. Concentration of Na was higher in Mex 69-290 which exhibited better performance than CP 72-2086. Sodium concentrations in leaves increased in direct relation to the tested NaCl concentrations. Mex 69-290 reached higher concentrations of Na in leave tissues but displayed better health than CP 72-2086. Thus, the variety Mex 69-290 showed more efficient Na-tolerance mechanisms related to Ca and K concentrations, and an indirect chlorophyll index better than CP 72-2086.
