A study on physiological mechanism of sorghum to aluminum (Al) toxicity and phosphorous (P) deﬁ ciencies was conducted using several sorghum genotypes in rhizotron. The study was conducted in the greenhouse of the University Farm, Bogor Agricultural University from August to October 2009. The experiment was carried out as a Factorial experiment in a Completely Randomized Design with three replications. The ﬁ rst factor was sorghum genotypes consisted of Numbu (tolerant) and B-75 (sensitive), and the second factor was combination of lime and phosphorous fertilization consisted of: no lime-no P (R1), no lime-low P (R2), no lime-sufﬁ cient P (R3), lime-no P (R4), lime-low P (R5) and lime-sufﬁ cient P (R6). The results showed that all variables were signiﬁ cantly affected by the interaction of media and genotype, except for length of shoot and total P uptake. Under low P and Al toxicity, sorghum variety Numbu showed a higher nutrient efﬁ ciency than B-75 with ability of forming greater dry mass. The sensitive genotypes showed a higher nutrient uptake but a lower P nutrient use efﬁciency under Al toxicity and P deﬁ ciency. Total P uptake and P nutrient use efﬁ ciency were highly correlated with root growth and dry material accumulation. Keywords: sorghum, Al toxicity, P deﬁ ciencies, P nutrient use efﬁ ciency, P uptake

Plant nutrient absorptions depend on their environment and plants’ stage of development. Beside from soil, nutrient absorption also proceed through resorption in leaves. The resorption efficiency varies based on types of habitat. Drought stress also influences the efficiency of nutrient resorption, growth rate, and plant development. The purpose of this research was to study the change of nitrogen (N) and phosphorus (P) content and leaf resorption value of N and P, and specific leaf area of 6-years old cacao grown under drought stress. Research was carried out in a cacao plantation with 7-years old Gliricidia sepium Jacq. as shading trees. The results showed that drought stress with Troughfall Displacement Experiment (TDE) system did not affect the content and resorption level of N and P of cacao leaves. However, N resorption of cacao leaves tended to increase while P resorption decreased. Cacao plants experienced drought stress have the ability to resorp leaf N for 46.64-50.63%, leaf P for 47.98-58.40%, whereas, the control plants had the leaf N resorption of 45.05-52.97%, and leaf P resorption of 36.64-44.10%. Drought stress for 13 months on 6-years old cacao did not affect specifi c leaf area.

The objective of the research was to identify RAPD markers linked to QTL related to agronomic traits of soybean under low-light intensity condition. The genetic material used in the QTL analysis based on RAPD Markers were Ceneng, Godek, and F6 RILs derived from hybridization between Ceneng (tolerant parent) and Godek (sensitve parent). The results of molecular analysis showed that 9 primers were polymorphic and linked to the tolerant parent. Primers produce 14 RAPD markers which were polymorphic and linked to the tolerant parent. The markers were distributed into a linkage group that containing seven markers. RAPD Markers (OPE15-800, OPM20-800) were linked to two QTL controlling number of productive node and seed weight, respectively. The marker linked to the tolerant parent could be used as a marker assisted selection for high-yielding soybean lines under low-light intensity

Recently planting site of sugarcane was shifted from lowland to upland area. Sugar cane cultivation in upland has many constraints, especially limited water supply and low nutrition availability. The objectives of this research were to study the influence of application of composted filter cake on growth and water use efficiency of upland sugar cane. The research was conducted in Jengkol, Kediri. Treatments consist of three factors: frequency of irrigation (once every 1 week, once every 2 weeks, and once every 3 weeks); sugarcane varieties (PS-862 and PS-864); and compost doses (0, 2.5, 5, and 7.5 ton ha-1). Split plot design with three replications was used in each irrigation treatment, using composted filter cake as main plots and sugarcane varieties as sub plots. The results showed that the highest sugar content was reached at application of 5 ton ha-1 compost and the greatest crystal sugar was reached at 3.09 ton ha-1 compost. Compost application at 5 ton ha-1 on each planted row can reduce frequency of irrigation from once a week to once every 2 weeks.

Water use efficient varieties in rice may have good opportunity in term of economic value and scarcity of water. This study was conducted to determine water consumption among rice genotypes that conventionally cultivated as low land (IR64, IPB97-F-15, Ciherang, Mentik Wangi, and Rokan hybrid), up land (Jatiluhur, Silugonggo), and amphibian type (Way Apo Buru, that could be planted both as lowland and up land). Rice seedlings at 14 days old were transplanted in a plastic container containing 83 kg of air dried soil, 1 plant per whole and 6 plants per container. The experiment was conducted in a vinyl house, using randomized complete block design with three replications. During rice growth, water table was maintained at 2 cm above soil surface, and water was added and recorded weekly. The results showed that varieties reveal production components and yield were different significantly. Water consumptions among varieties were significantly different, ranged from 15.93 L plant-1 for IR64 to 24.13 L plant-1 for Jatiluhur, or equal with 3,639 to 4,827 m3 ha-1. Jatiluhur was the most efficient variety in using water. This finding may guide us to explore benefit of water use efficient variety as sustainable option in water management of rice cultivation.

The aim of this study was to characterize full length sequence of JJ3 isolated from shade tolerant soybean. The characterization of full length sequence involved analyses of structure of full length sequence, open reading frame (ORF) or coding sequence (CDS), and homology. The analyses of JJ3 full length sequence structure were done using GeneScanW program, coding sequence (CDS) or open reading frame (ORF) using ORF Finder program, and the homology of JJ3 full length sequence were done using BLAST and clustalW programs. Results showed that the full length sequence of JJ3 consisted of single exon and polyA. Single exon was a coding sequence (CDS) 633 bp produced open reading frame (ORF) with 210 amino acid deduction comprised of 136 conserved amino acids and 77 varied amino acids. The conserved domain of JJ3 produced functional protein, PsaD photosystem I (PSI) subunit, related to photosynthetic transport electron in PSI reaction center. The full length of JJ3 homolog to psaD, a gene encoding protein subunit photosystem I (PSI) related to mechanism of plant adaptation to shade stress, in wood tobacco (Nicotiana sylvestris), rice (Oryza sativa), tomato (Lycopersicon esculentum), barley (Hordeum vulgare), spinach (Spinacia oleracea), Arabidopsis (Arabidopsis thaliana), and potato (Solanum tuberosum).Key words: full length sequence, gene, homology, shade tolerant, soybean
