Abstract

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.

Abstract

The aim of this research was to study the growth of sugar palm seedling from different altitudes of mother plant, growing in different organic media. The experiment was conducted at Seed Technology Laboratory and Academic Garden of Agronomy Department, Faculty of Agriculture, Tadulako University, from February to July 2008. The experimental design was factorial randomized block design with two factors. The first factor was seed from different altitudes of mother plant sources, i.e, : from Parigi (<500 m asl), from Palolo (500-1,000 m asl), and from Napu (>1,000 m asl). The second factor was types of organic fertilizers added on soil taken from sugar palm land. The organic fertilizer treatments were without fertilizer, manure, compost of rice husk, and sugar palm residue. Each experimental unit was comprised of 25 seeds with three replications. The results showed that seeds from Parigi grown in media with compost of rice husk gave a better growth than other treatments. Germination percentage at this treatment was 88.01% and dry weight of seedlings was 0.41 g in average, eligible to be transferred to main nursery.

Abstract

Potassium (K) is required in a large amount for plant growth and production of most fruit crops, including pineapple. However, excess application may decrease its growth and production. Therefore, fertilizer application must be site specifi c, based on soil nutrient status and plant requirements. The aims of the research were (1) to determine the soil K nutritional status of pineapple and (2) to determine the optimum dosage of K fertilization for pineapple grown in Sawah Baru, Darmaga, Bogor. The research was conducted using split plot randomized block design with fi ve soil K status as main plots i.e. 0, 70, 140, 210, and 280 kg K2O ha-1 representing status levels of very low, low, moderate, high, and very high, respectively. The sub plot was dosage of K fertilizer i.e. 0, 200, 400, 600, and 800 kg K2O ha-1. The result of the research showed that plant growth and production of pineapple were improved by soil K nutrient status and dosage of K application. The level of soil K nutrient availability was classifi ed into low (<14 ppm K2O), medium (14-50 ppm K2O), and high (>50 ppm K2O). Potassium fertilizer is recommended for the soil with low soil K status of 634 kg K2O ha-1 .

Abstract

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

Abstract

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.

Abstract

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.

Abstract

Phosphorus (P) deficiency is one of major problems in rice cultivation. Development of a tolerant variety to P deficient soil is expected to reduce the needs of P fertilizer. The aim of this research was to evaluate the agronomic performance of Pup1-introgression rice lines. This research consisted of two separate experiments, an evaluation on rice grown in nutrient solution in the greenhouse of ICABIOGRAD, Bogor; and field evaluation at upland rice screening site Taman Bogo, Lampung. The rice lines used were BC2 F3 derived from crossing of Situ Bagendit with Kasalath and NIL-C443, and from crossing of Batur with Kasalath and NIL-C443. Molecular analysis was conducted to verifiy the Pup1 introgression in the lines used and successfully confirmed the occurance of homozygote Pup1 segment in those lines. Evaluation of rice lines grown in nutrient solution was performed in a split plot factorial design, using the dose of Al (0 and 45 ppm Al3+) as main plots and dose of P (0.5 and 10 ppm P) as subplots. Field evaluation was performed in split plot design, with P fertilization (0 and 500 kg SP-18 ha-1) as main plots and BC2 F3 lines as the subplots. Evaluation using Yoshida nutrient solution showed that the BC2 F3 lines had greater total dry weight under low-P condition (37.5-112.5%), especially under Al-toxicity, compared to the respective parental varieties (Situ Bagendit and Batur). Field evaluation showed that the Pup1-introgression lines had greater shoot dry weight than the respective parental lines (10.5-74.82%). However there was no significnant effect of Pup1 introgression in terms of weight of filled grain.

Abstract

The objective of this research was to determine the trait variance in black soybean lines in terms of yield and yield components. The materials used were F8 lines generated from hybridization of two local varieties, i.e. black seeded Ceneng and greenish yellow seeded Godek, and then selected under single seed descent method, except  SC-39-1, SC-62-2 and GC-74-7 that were generated through bulk selection method. The results showed that the traits between plant genotypes were significantly different, except number of productive node and number of unfilled pod. Total variance was contributed more by number of filled pod, seed weight per plant and 100 seed weight.  Seed weight per plant and 100 seed weight had high heritability with genetic variance and broad-sense heritability which were significantly different from zero. These characters are important for further selection to improve yields of black soybean lines.Keywords: black soybean lines, broad sense heritability, total variance

Abstract

Drought inhibits several physiological process and induces oxidative stress due to the enhanced production of reactive oxygen species (ROS) mainly in photosynthetic apparatus. Silicon (Si) is known to increase tolerance of rice against drought stress.  However, long period of intensive crop cultivation depleted the available soil Si by approximately 11-20%. Rice husk ash (RHA) is potential Si source. The objective of this research was to analyze the potency of RHA through pot experiment to observe: 1) internal water balanced; 2) integrity of cell membrane and  antioxidant content; and 3) production of tolerant cultivar ‘Segreng’ and sensitive one ‘Cempo merah’. Application of RHA was at level of 0, 4, and 8 tons ha-1. Drought stress was imposed by with holding water until soil water content reached 50% of field capacity (moderate stress) and 25% of field capacity (severe stress). Application of RHA significantly increased leaf relative water content and membrane stability index of rice ‘Segreng’ and ‘Cempo merah’. Tolerant cultivar ‘Segreng’ had better response than ‘Cempo merah’ as shown by greater leaf relative water content under moderate and severe stress. RHA application at level of 8 tons ha-1 increased index of membrane stability and level of antioxidant (AAred and α-tocopherol) which determine production of both rice ‘Segreng’ and ‘Cempo merah’ during drought.Keywords: antioxidant, field capacity, membrane stability, segreng cultivar, α-tocopherol

Abstract

Area of ratoon cane (RC) in Indonesia is more than 75% of total area of cane with productivity lower than plant cane (PC). To improve the productivity proper fertilizer application is required in accordance with the planting system used. This study was aimed to acquire a package of NPK compound fertilizer efficient for several planting systems of ratoon cane. The experiment was conducted in Muktiharjo Research Station, Pati in October 2013-September 2014. Two packages of compound fertilizer, i.e. 15N:15P:15K:10S formula package (500 kg compound fertilizer + 600 kg ZA ha-1) and 16N:8P:18K:2S:2Si formula package (500 kg compound fertilizer + 100 kg ZA ha-1) were arranged in randomized block design with four replications. Both packages were applied to two single row planting systems and two double row planting systems. The results showed that in single row planting system with both center - to - center (ctc) distances, i.e. 130 and 110 cm, the application of 16N:8P:18K:2S:2Si formula package resulted productivity, sugar content, and sugar yield that are no different from those with 15N:15P:15K:10S formula package. However, in double row planting systems with ctc 50/170 cm, 16N:8P:18K:2S:2Si formula package increased 9.20% sugar yield. The profit from 16N:8P:18K:2S:2Si formula package (12.07 million-14.23 million rupiah ha-1) in single row planting systems were lower than that of 15N:15P:15K:10S formula package (13.15 million-15.15 million rupiah ha-1). However in double row planting systems with ctc 50/170 cm, 16N:8P:18K:2S:2Si formula package produces profits (39.92 million rupiah ha-1) higher than with 15N:15P:15K:10S formula package (28.49 million rupiah ha-1).Keywords: planting-system, productivity, sugar-content, sugar-yield
