Some of rhizobacteria have been known to stimulate the growth of some crops through their fitohormon (IAA = indole acetic acid). Those rhizobacteria can stimulate the development of epidermis cells formation at root hair site and increase the infection sites to increase the nodulation and N2 fixation. The aims of this study were to study the effect of Rhizobium strains inoculation and indole acetic acid (IAA) application on crop growth, root nodulation. and N, P uptake of soybean on the Ultisols. The greenhouse experiment used Completely Randomize Design (CRD) with four replications. The treatments were: I) Without inoculation (blank), 2) 100 ppm N application, 3) 0.4 ppm IAA application, 4) Inoculation of Rhizobium 1004 (106), 5) Inoculation of Rhizobium 1004 (I05) + IAA, 6) Inoculation of Rhizobium RD-20 (104), 7) Inoculation of Rhizobium RD-20 (106), 8) Inoculation of Rhizobium SNI-2 (106). 9) Inoculation of Rhizobium SNI-2 106 + IAA. Result of the experiment indicated that inoculation of Rhizobium and IAA application increased crop growth, nodulation, and nutrient uptake of soybean. Inoculation of Rhizobium I004(106). RD-20(104)R, D-20(I06),S NI-2(I06), and IAA 0.4 ppm increased dry weight of crop by 33.5%,37.8,17.3%,35.1%,and 3.8% respectively compared to blank. Application of IAA at Rhizobium inoculation treatment of SNI-2(106) and 1004(106i)n creased dry nodule weight on soybean 40.9%, and 55.7 % respectively compared to without IAA application.

Dioscorea was a member of Dioscoreaceae, ordo of liliales and class of Monocotyledoneae, Two types of Dioscorea were annual and perennial. As much as 50-60 species of 600 species was cultivated as food source. This research was conducted to study tuber characters and nutrition content of Dioscorea sp. Plant material was Dioscorea collection from some places in Indonesia. Five accessions of Dioscorea alata. Dioscorea esculenta and Dioscorea hispida. were analyzed for the content of fat, protein and starch. Tube characters observed were tuber number, tuber weight, length and diameter. There were significant differences of tube character, protein and starch content between Dioscorea accession. The highest tuber weight and starch content were resulted by D.alata especially accession number 49. The highest protein content was resulted by accession number 67 of D. esculenta. Positive correlation between tuber diameter and tuber weight of D. alata showed that higher accumulation of fotosynthate was followed by increasing tuber diameter. In other words, sink capacity was determined by tuber diameter. Key words: Tuber, Dioscorea spp., Nutrition content

This research was aimed to find out the tolerant and susceptible soybean genotypes to drought stress. Twenty two genotypes were tested on three levels of drought stress, based on soil moisture conditions: 80% of field capacity (FC ), 60% FC and 40% FC. The experiment was conducted in plastic house at the experimental field of Meteorological Station, Sampali, Medan, from February to May 2000. The results show that increasing on the severity of drought caused significantly reduced growth and yields, which indicated by the reduction on shoot dry weight, stem diameter, filled pod number, seed number/plant and seed dry weight. The level of growth and yield reductions varied 1 among genotypes. The highest variation was shown at the drought level of 60% FC. Sindoro and Lokon were selected as tolerant and susceptible genotypes, consecutively. It was concluded that the adaptation of tolerant plants strongly related to their ability to improve the root system and to reduce the transpiration surfaces. Key words: Soybean, Drought, Tolerant, Susceptible

Potatoes can be severely affected by late blight, a fungal disease caused by Phvtophthora infestans. which can destroy the foliage and tubers of the crop. Initial attempts to control late blight in potato deployed resistance genes (R genes) derived from the hexaploid Solanum demissum (RI - Rll). However, their immunity reaction can be easily overcome by the development of new virulent factors. It is currently accepted that the most effective solution against late blight involve the use offield-resistant varieties as part of an integrated pest management strategy. Field resistance to Phvtophthora i!!festans were examined in a diploid segregating potato population. The population produced crosses between Solanum microdontum genotype (MCDI67) and ~ tuberosum genotype (SH2988) have been assessed for resistance to f.. infestans (late blight) in the field and prol1ed to segregate for f.. infestans resistance. A genetic linkage map of this population was constructed by using PCR-based CAPS markers. The result showed that one QTL on foliage resistance to late blight were linked with marker GP 180 on chromosome 4 of potato in coupling phase. Key words: CAPS markers, Field resistance, Late blight, Phvtophthora infestans. potato, QTL

Two parallel experiments were conducted to study the effect of training and pruning on the growth and development of durian. Two-years old durian clones Matahari and Monthong had been pruned and or trained for 19 months as open center, central leader, palmette leader and left untreated (control treatment) in five (for Matahari) and six (for Monthong) replications. Training and pruning treatments resulted in more open crown as indicated by lower (35 - 40%) leaf area index, better growth analysis as indicated by better dry matter partition and growth rate. Relative growth rate (RGR) and net assimilation rate (NAR) of trained and pruned trees were high during 12 - 15 months after treatment, although their absolute growth rate cumulative crown dry matter low compared to untreated trees. Compared to pruning \, training treatment gave higher contribution to NAR. Due to wet climate of local Bogor and ontogeny of the durian used in this experiment (at late juvenile stage, 3.5 year old durian), the effect of training and pruning on the development of the durian as observed by flushing phenology had not been revealed. Flushing rhythmic pattern of treated and untreated durian were almost same. Key words: durian, tree architecture, training, pruning, phenology.

The experiment was aimed to study the quality and shelflife of Fremont fruit harvested from different land elevation. Fruit were harvested according to orchard harvest criteria. The experiment used Randomized Complete Design, with the treatment of land elevation level i.e. 500 - 600 m, 600 - 700 m, 700 - 800 m above sea level. Land elevation level influence peel color, at the higher land elevation level the orange color on peel was more appeared. Land elevation level in the range of 500 - 800 m above sea level did nor affect firmness and total soluble solids (TSS) content in fruit juice at harvest time, however there was a tendency that higher acid and vitamin C content were observed in fruit of tree grown in the higher land elevation. The decrease on weight of fruit, fruit firmness, acid and vitamin C contents and increase of TSS content were observed during storage. The fruit of Fremont not be stored more than four weeks, because in this experiment, the fruit at four week after harvest experienced significant weight loss and severe peel shrinkage they resulted in unmarketable fruit.
