Abstract

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.

Abstract

The experiment has been conducted in Labuhan Dalam, Tanjung Seneng, Bandar Lampung from January to June 2008. This experiment consisted of 3 subtitles that are: (1)The effect of root stock age and shading degrees on physic nut plant propagation with grafting. Is a factorial experiment (3x4) with split plot design, shading degrees as main plot consisted without shading, light shading), moderate shading, and heavy shading .Root stock age as subplot consisted 6, 8, and 10 weeks after transplanting; (2) The effect of root stock high and scion length on physic nut plant propagation with grafting. Is a factorial experiment (3x3) with randomized completely block design, the first factors were root stock high consisted 10, 15, and 20 cm from nursery medium. The second factors were scion length consisted 5 cm, 7,5 cm, and 10 cm; (3) The effect of kind of bend and IBA concentration on physic nut plant propagation with grafting. Is a factorial experiment (3x3) with randomized completely block design, the first factors were kind of bend consisted raffia rope, plastic rope, and faucet cellophane tape rope. The second factors were IBA concentration consisted 0, 1000, and 3000 ppm. The treatments were consisted 3 replication and each experiment unit consisted 10 seedlings. The result shows that (1) root stock age 8 and 10 weeks produces physic nut seedling growth better than root stock age 6 week. Physic nut seedling without shading and light shading (1 layer paranet) grow better than with moderate shading (2 layers paranet) and heavy shading (3 layers paranet); (2) Root stock high 15 cm produce physic nut seedling growth better than root stock high 10 cm and 20 cm. Length of scion 7,5 cm and 10 cm produces physic nut seedling growth better than length of scion 5 cm; (3) Plastic and faucet cellophane tape rope produce physic nut seedling growth better than raffia rope. IBA concentration 1000 and 2000 ppm produces physic nut seedling growth better than o ppm Keywords: Physic nut, root stock, seedling, grafting

Abstract

Hybrid corn is a first generation (F1) from the cross between two or more inbred line. Hybrid maize seed produced in Indonesia by BISI, PT.Du Pont Indonesia, and Syngentha. Inbred line as seed imported from abroad. In Indonesia the company only produce F1 hybrid seed corn. The problem for Indonesia is a very large dependency needs seed hybrid corn to foreign countries.Polinela current tread olready up 13 single-cross maize hybrid with inbred line the assembly itself in Polinela. Research aims to find the groove single cross corn hybrids that have superior characters in the quality and quantity.Research conducted in Polinela, Maret 2009 until July 2009. Research conducted with Randomize Completly Block Design (RCBD) as the treatment were 13 single cross maize hybrid assembly Polinela. Use as a benchmark Pioneer 23 (P-23), all treatment repeated three times. To know the differences between the treatment then continued with Least Significant Different (LSD) on stage 5%. Results of the research potential of 13 single cross hybrid there are (1) Generally assembly Polinela hybrid have caracteristics not significant rather than P-23, (2) Two assembly Polinela hybrid that has the potential of higher than P-23, that is hybrid C (PL. 401xPL. 201) and Hybrid K (PL. 20xPL.401).

Abstract

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

Abstract

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. Keywords: fertilization, seed, soybean, harvest
