Dioscorea is potentially used as staple food to support food security. The research was aimed to determine the effect of stake length and time of stem twining on the growth of Dioscorea sansibarensis Pax. The experiment was conducted in Purwodadi Botanic Garden from December 2014 until May 2015 using split plot randomized block design consisted of two factors, i.e. the stake length and time of stem twining. The stake length was the main plot consisted of 150 cm, 100 cm and 50 cm above soil surface and without stake (control). The time of stem twining as subplots, i.e. stem twined early, twined at the time of 4 leaves stage, and twined at 8 leaves stage. Each combination of the treatments was replicated three times. The results showed that there was significant effect on the stake length and the time of stem twining treatments on the plant growth and yield. The stake length of 150 cm treatment produced the highest fresh tuber and total plant dry weight, i.e., 257.24 g and 132.77 g per plant, respectively. On the contrary, the plant without stake produced the lowest fresh tuber and total dry weight of plant, i.e., 112.10 g and 48.65 g per plant, respectively.<br /><br />Keywords: biomass,leaf area, photosyntesis, tuber weight

ABSTRACT In vegetables, especially the leafy ones, nitrogen (N) and water are essential in its growth, being N the second most absorbed and identified nutrient in the arugula leaf tissue. Water is essential for horticultural crops, so its use must be rational in order to achieve high yield. The objective of this study was to evaluate the effect of nitrogen levels and irrigation depths on the productive characteristics, the total leaf chlorophyll index (ICF) and nitrogen contents in the arugula culture. The experiment was arranged in a randomized block design subdivided in plots, with two factors: A) nitrogen levels applied in coverage (25, 50, 100, 125 and 150 mg dm-3) and B) irrigation depths [(50 and 100% of the available water capacity (AWC)]. At harvest, 37 days after transplantation (DAT), we observed a significant effect of the treatments when individually analyzed, and also a significant interaction between factors of the analyzed variables. The nitrogen content in the plant showed no effect for irrigation depths. However, the highest content was found in the level of 129 mg dm-3 (27.8 g kg-1), corresponding to an increase of 26% in relation to the lowest level (25 mg dm-3; 22.07 g kg-1). In conclusion, the supply of 150 mg dm-3 nitrogen and full irrigation management (100% of AWC) provided substantial increase in height, leaf area and fresh mass of aerial part of the plant.

Chromolaena odorata (L.) is a potential compost since it has high biomass and contains calcium, manganese, potassium and nitrogen. The aim of this research was to know the potency of siam weed Chromolaena odorata compost on soil chemical and chili plant performance. The experiment was arranged in factorial randomized block design consisted of two factors and three replications. The first factor was variety of fertilizer (no fertilizer, cow manure, siam weed compost and inorganic fertilizers) and the second one was the tanglefoot (with and without tanglefoot). Overall, the results of study showed that C. odorata compost could increased crop performance when compared with the other fertilizers in terms of number of fruits, fresh/dry weight of fruits, dry weight of crops, and N-total (leaf, stem, root and fruit), though there was no difference in fresh weight of crops among treatments. Furthermore, the effect of siam weed compost was not significantly different on soil chemical if compared with all treatments. This study is likely suggesting that C. odorata compost gives a positive effect to crops performance and soil chemicals.Keywords: Chili, Chromolaena odorata, compost fertilizer, tanglefoot

Nutritional Characteristics

The objective of this study was to evaluate the influence of five levels of N and two regrowth intervals on the structural, productive, and nutritional characteristics of Tifton 85 grass (Cynodon spp). The experiment was conducted in a hay production field at the State University of West Paraná, planted in 2004 with Cynodon spp. cv. Tifton 85. The experiment was established in a randomized block design with factorial treatments of five N fertilization amounts (0, 25, 50, 75 and 100 kg ha-1 cut-1) applied as urea after each cut, and two regrowth intervals (28 and 35 d), with four replicates. N application promoted changes in plant structure, such as increased canopy height, stem length, leaf elongation rate, and dry mass (DM) production. The greatest N use efficiency, considering the four harvests, occurred in the plot with 25 kg N ha-1 cut-1 at the 35-d interval, with a production of 13.79 kg DM kg-1 of N applied. A nutritional analysis indicated that 100 kg ha-1 of N cut-1 promoted higher crude protein (CP) at 28 d, with the highest concentration observed in the fourth cut (208.2 g kg-1 DM) and the lowest in the second cut (140.12 g kg-1 DM). The content average in the four cuts for CP and LIG at 28 days of regrowth was 175.85 and 104.33 kg-1 g MS and at 35 days of regrowth interval was of 164.45 and 118.65 g kg-1 DM, respectively. No differences were found between regrowth intervals in the contents of mineral matter and acid detergent fiber (ADF). Environmental factors including the wide variation in precipitation (greater than 200 mm between the peak in December 2010 and the lowest in March 2011) greatly influenced Tifton 85 grass production, affecting DM and the nutritional value of the forage in each cut.

The main problem encountered by soybean crop in acid sulfate tidal lands is less availability of P, because of its chemical bond with Fe. Heavy dose of fertilization often lead to high fertilizer residue, wich could be used for crops farming using AMF. Research was conducted to study the effect of soybean culturing technique and AMF inoculants source on growth of soybean. The treatments consisted two factors, arranged in a randomized block design with three replications. The first factor was four inoculants sources of AMF, namely AMF and without inoculation AMF, inoculants from rhizospheres of kudzu (Pueraria javanica), sorghum (Sorghum bicolor), corn (Zea mays) and soybean (Glycine max). The second factor was culturing tehnique, namely water saturated and dry soil culture. Soybeans were grown in pots containing 5 kg soil derived from tidal land, Simpang Village, District of Berbak, East Tanjung Jabung Regency, Jambi Province. Results showed that the interaction saturated soil culture with inoculants from corn’s rhizosphere had positive effect on the variability of N, P and K uptake, N and P content in the plant, relative efficiency of inoculants and relative efficiency of P uptake, stem diameter, biomass dry weight, the number of filled pods and seed dry weight of soybeans. Dry soil culture with inoculants of corn’s rhizosphere had greater root colonization, but overall for the growth and grain yield of soybean, saturated soil culture with inoculants from corn rhizosphere has better effect on other growth variables.
