Abstract

ABSTRACTDrought stress in crop occurs due to imbalance between demand and supply of water. Crop responses to drought stress depend on their genotypes. Drought stress causes anatomical changes and root damage. The objective of this research was to study the effect of drought stress on anatomy and physiology of soybean root. The research was conducted at Laboratory of Microtechnique, Department of Agronomy and Horticulture, Bogor Agricultural University in November 2013. A Completely Randomized Design with two factors was used in the research i.e. soybean genotypes (Wilis, PG 57-1, SC 39-1) and PEG (0, 20%) with three replications. The result showed that genotype and PEG affected the size of the cortex, stele, and xylem. PG 57-1 genotype showed the decrease of cortical thickness, diameter of stele and the diameter of xylem, on the other hand, in SC 39-1, there was an increase. Drought stress (PEG 20%) could also cause damage to the root membrane as indicated by the occurrence of lipid peroxides. Wilis and PG 57-1 were tolerant while SC 39-1 was sensitive to drought stress.Keywords:cortex, lipid peroxides, PEG, Schiff’s reagent, xylem

Abstract

ABSTRACTBlack cumin (Nigella sativa L.) is a native medicinal plant to subtropical West Asia and the Mediterranean regions. So far, information regarding black cumin fertilization is still limited. The objectives of this study was to obtain the optimum rate of N and P fertilizer in order to promote the growth and production of black cumin under tropical climates. This research was conducted at Manoko Experimental Station, Lembang, West Java from October 2012 to January 2013. The research was arranged in randomized complete block design with two factors and three replications. The first factor was four rates of N fertilizer (0, 40, 80, 120 kg N ha-1), and the second factor was four rates of P fertilizer (0, 40, 80, 120 kg P2O5 ha-1). The results showed that application of N and P fertilizers increased plant height, leaf number, branch number, leaf area, leaf area index, relative growth rate, net assimilation rate, plant dry weight, number of capsule per plant, number of seed per capsule, seed weight per plant, and weight of 1,000 seeds. Moreover, growth and production of black cumin still increased at the highest rates of N and P fertilizers, therefore, it is necessary to study for N and K at higher rates in order to obtain optimum production rate.Keywords: medicinal plant, rate of fertilizer, tropical

Abstract

The productivity of forage is strongly influenced by cutting height and interval of defoliation. Experiment was conducted at the Research Institute for Industrial Plants and Other Palm (BALITKA) Manado since June 2008 until April 2009. The objective of the experiment was to find out the effects of intensity and intervals of defoliation on dry weight production and the quality of nutrients. The experiment was arranged in factorial RCBD. The intensity of defoliation was based on cutting height, i.e. 5, 10, 15 cm, whereas the intervals of defoliation were 30, 45, 60 day and 456.54 Degree Days (DD). The data of dry weight production, leaf stem ratio, nutrient quality were collected. The results showed that there were significant effects of treatments on all parameters. Productivity of B. humidicolai terms of high dry weight yield, high leaf stem ratio and crude protein, low crude fiber and acid detergent fiber (ADF) content were found in the interaction of intensity 10 cm with the interval of defoliation among the vegetative development stage of 30 and 45 days, as well as the interval of defoliation based on heat unit accumulation of 456.54 DD. The research implies that a cutting height at 10 cm and interval of defoliation as mentioned above is ideal for B. humidicola. Utilization of growing degree days (GDD) to determine the appropriate time for defoliation is considerable under this experiment.Keywords: B. humidicola, defoliation, forage, nutrient, productivity

Abstract

Iron (Fe) toxicity is a major constraint in rice production that decreases yield due to high level of soluble Fe. The aims of this experiement were to study the effect of particular Fe concentrations in nutrient solution on rice growth, and to determine Fe concentration in nutrient solution that caused light, moderate, and severe Fe toxiciy symptom. The experiment was conducted in a greenhouse, Bogor Agricultural University from May to July 2010. A randomized block design with two factors and three replications were used in this study. The first factor was Fe concentration in the medium solution (2, 50, 100, 200, 400, 600 ppm Fe), and second factor was rice genotypes (IR64, Margasari). The results showed the higher Fe concentration in the solution resulted in higher scores of iron toxicity symptoms, higher Fe levels in the plant, and caused stunted growth of rice plants. Levels of Fe in a solution of ≥ 200 ppm Fe inhibited plant growth. Iron toxicity symptom in Margasari was lower than the IR64 varieties, especially at concentrations of 200 and 400 ppm. According to the regression equation Y = 0.022X+ 1849, Fe concentration in the solution which caused light Fe toxicity symptom (score ≤ 3) was ≤ 52 ppm Fe, moderate (score = 5) was 143 ppm Fe, heavy (score = 7) was 234 ppm Fe, and severe (score ≥ 9) was ≥ 325 ppm Fe. Keywords: iron toxicity symptoms, iron concentration, rice

Abstract

Soybean (Glycine max L. Merrill) demand is high in Indonesia, however national production is low, therefore improving productivity is important. The research was aimed to determine the effect of application of biofertilizer containing N- fixing and P- solubilizing bacteria on the growth and production of soybean in lowland swamp. The experiment was conducted  at  Labuhan Ratu VI Village, District of Labuhan Ratu, East Lampung Regency from September to December 2014. The experiment was arranged in factorial randomized block design with three replications. N and P fertilizers were applied in four levels. Doses of N were 0, 11.25, 22.50, 33.75 kg ha-1, doses of P were 0, 36, 72, 108 P2O5 kg ha-1, in combination with and without biofertilizer application. The results showed that interaction between biofertilizer and N significantly affected number of branches and number of leaves at maximum vegetative phase. The influence of three types of fertilizer had no significant effect on the productivity of soybean in lowland swamp with soil pH of 7.0 and medium soil fertility. It is recommended to apply Biofertilizer + 11,25 kg N ha-1 + 36 kg P2O5 ha-1 to obtain high soybean production in lowland swamp area.Keywords: nitrogen, phosphate, productivity, soil fertility

Abstract

The effects of nitrogen fertilizer on agronomic and morphological characters depend on several factors such as genotypes and nitrogen rate. The study was aimed to evaluate nitrogen effects on rice panicle. A field experiment was conducted at Babakan Research Station during November 2015- February 2016 using a split-split plot design with three replicates. Nitrogen doses was a main plot, genotypes was a subplot, and time of application was a sub-subplot. A greenhouse experiment was carried out at PAIR, Jakarta during February-July 2017 using a completely randomized design with three replicates. The results from the field experiment indicated that the highest panicle number (13.25), number of filled grains (177.94) and spikelet number (213.76) were obtained at doses of 450 kg urea ha-1. Analysis of variance showed that the genotypic effects were significant for all traits observed, while the interaction effect between genotypes and time of nitrogen application was significant on the length of first grain from first node. However, the three-factors interactions were not significant for all traits. The greenhouse experiment revealed that both genotypes and N rates significantly affected all traits except for panicle number and the length of first grain from first node, respectively, while their interaction only significant for number of primary branch. Nitrogen increased all traits observed except the length of first grain from first node. Simultaneously, both experiments showed significant effects of genotypes for all traits observed. Doses of urea fertilizers above 400 kg ha-1 could improve the performance of panicle traits in order to increase yield potential.

Abstract

The objective of this research was to study the morphology and physiology of jatropha leaves and its relation to photosynthesis. Research was conducted using Randomized Complete Block Design with single factor, i.e., leaf ages at the canopy with ten replications. The results showed that jatropha had phyllotaxy 5/13 with angular divergence 1380 . In early growing leaf enlarged sharply and then constant after 9 week, remaining green for 14 weeks. Chlorophyll a, b, and total achieved maximum at 9 week, i.e., 0.45 g/cm2 , 0.19 g/cm2 , and 0.62 g/cm2 , respectively. Photosynthesic rate was maximum at 6 week, i.e., 8.99 µmol/m2 /s, while number of stomata was maximum at 9 week (289.47 mm2 ). This finding implies that leaf number 11 to 13 or age 6 week after emergence could be used as reference for photosynthetic evaluation.

Abstract

A study to explore the agronomic response of some soybean genotypes to temporary flooding in the type-B overflow tidal swamp and to obtain the adaptive genotype to the environment was arranged in a split-plot design at coordinates 2°64’46.77” S and 104°75’27.75” E with an altitude of 3.5 m above sea level. The main plot was subject to short-term flooding with a variety of cultivation technologies consisting of saturated soil culture (SSC) for one month without flooding, SSC for one month with flooding, SSC during plant growth without flooding, SSC during plant growth with flooding and non-SSC/dry cultivation. The subplot was soybean genotype consisting of 6 genotypes: Tanggamus, Karasumame (Naihou), M652, Anjasmoro, M100-47-52-13, and Tachinagaha. The result showed that impaired soybean growth at the beginning of the growth stage caused pressure on the later growth stage and decreased soybean yield. Short-term flooding reduced the soybean yield. The non-tropical genotypes of Karasumamae (Naihou), M652 and Tachinagaha produced the lowest yield of seeds; 20% lower than the tropical genotypes of Anjasmoro, M100-47-52-13 and Tanggamus with SSC during plant growth without flooding treatment. The Karasumame (Naihou) genotype produced the highest seed yield of the three non-tropical genotypes. Anjasmoro and M100-47-52-13 produced the highest seed yield at temporary flooding.
