The objective of this study was to evaluate the effect of dosages NPK and harvest day on seeds viability. The study was conducted at the experiment station of Polinela, Bandarlampung and Seed Laboratory, Unila from Januari to June 2008.Treatment consicted of two factors arranged in factorial design (5x7). A Split plot design with three replications was used. The main plot factor was NPK dosages, i.e., 0, 25, 50,75, and 100 kg.ha-1. The Subplot factor was harvest day, i.e., R7, R8, R8+3, R8+6, R8+9, R8+12, R8+15. Examination of hypothesis done with regression analysis at significance level 5%. Interaction between fertilizer doses NPK supplement and harvest day influences initial vigour of variety soy seed Anjasmoro. Germanation uniform and germination speed can be improved with addition of NPK supplement to 100 kg/ha though harvested at R8+15 day while at harvesting since R8 until R8+12 day, initial vigour not reality; phase R8 or day 81stafter planting. Harvest day 88-89th after planting or R8+15 day to yield maximum initial vigour based on variable germination speed ( 30,19 %/day) if dose NPK supplement is improved to 100 kg/ha. Harvest R7, germination seed are still increase at various doses NPK supplement while harvesting since R8 until R8+15 day, the influence of germinates power is not significant.

The research was to study the interaction between crop lettuce and tomato under intercropping system, its effect straw mulch on growth and yield of both crop. The experiment was conducted at the Mujimulyo village, Natar. The experiment was conducted from April until July 2008. The Strip Plot Design was used with two factors and three replication. Intercropping followed additive series system: the first factor was croppings, i.e.: crop lettuce 100%, crop lettuce 75% : tomato 25%, crop lettuce 50% : tomato 50%, crop lettuce 25%: tomato 75%, and tomato 100%.The second factor was straw mulch, i.e.: no mulch, 4 and 8 ton ha-1. Experimental results showed that: (1) Straw mulch treatment did not effect on growth and plant yield, but croppings conferred effect to plant yield. (2) In intercrop, the two crop interacted leading to an increase of tomato yield but a decrease in crop lettuce. Graph of the replacement series indicated a compensation with respect to crop yield. (3) The best scheme with regard to yield was 50%:50% intercrop as it had a retative yield total 1,17. Keywords : interaction, straw mulch, crop lettuce, tomato, intercropping.

Sweet bread is a very popular food in Indonesia and the quality is largely determined by the filler used. Today, the bread is very varied filler that are the fruit aroma to chopped meatballs. The meatballs as a filler of sweet bread can only self life for no longer than 2 days, therefore it needs a preservation effort. One of technical preservation was application of liquid smoke. The research objective was to characterize of the meatballs as filler and of liquid smoke of coconut cell and to know the effect of concentration of liquid smoke to self life of sweet bread filled meatballs in storage. The results showed that dipping the meatballs in a liquid smoke was lowered taste, but only slightly affected the color, surface mucus, texture, and preference until the third day. The higher concentration of liquid smoke was the lower of total microbes in the meatball during storage. Liquid smoke was not advisable as a preservative in bread balls for sweet bread filler, because the concentration of smoke liquid 2% only decreased the bread taste. Keywords: Liquid smoke and meatballs bread filler

Standard PK fertilizer (100 kg. ha SP 36 + 100 kg / ha-1KCI) dose AMOGRO ½-s, 5). Standard PK fertilizer+¾ Amogro_S dose, 6). Standard PK fertilizer + 1 dose Amogro-S, 7). Standard PK fertilizer +1 ¼ Amagro dose-S and 8).Standard PK fertilizer dose of 1 ½ Amagro-S. Research design using a randomized block design with 3 replications. The results showed that the fertilizer-S amagro meet the quality requirements that have been established as a solid organic fertilizer. Fertilization amagro=S at a dose of 2000-6000 kg. Ha-1 with P and K in high doses to plant standards, the number of seedling weight and 1000 grain harvest of dry grain weight (GKP) is not significantly different in nominal terms even better compared with the dose of fertilizer N, P and K standards. Dry grain harvest Hasik / GKP highest (5.850 t / ha) achieved by the treatment of 4000 kg.ha-1Amagro-S disetai with P and K fertilizer at standard doses. Fertilization Amagro-S from 2000 to 6000 kg.ha-1along with P and K fertilizer at standard doses can increase the Relative Agronomic Effectiveness (RAE) between 18,40-69,33% higher. While the use of fertilizer Amagro-S at a dose of 4000 kg / ha of fertilizer without P only gives rise RAE of 3.99%. Solid organic fertilizer / bulk Amagri-S can be used for paddy rice, but the monitoring needs to be done soil properties on the usage of fertilizer-S Amagro long term.
