Abstract

The research was conducted to investigate the effect of copper (Cu) levels in irrigation water on the growth and production of rice variety IR64. The experiment was arranged in randomized complete block design with six replications. The Cu treatments were: 0, 300, 600 and 900 mg Cu L-1of irrigation water. The results showed that Cu content significantly decreased rice growth and production. Copper level of 600 mg L-1 decreased plant height, tiller number and leaf number. Copper level of 300 mg L-1 decreased panicle length, number of grains per panicle, empty grain weight, 100 grains weight, milled grain weight, and shoot dry weight. This experiment implies that remediation treatments should be considered when Cu level in irrigation water was more than 300 mg Cu L-1. Copper level of 300 mg L-1 could be used as a critical level for rice screening for Cu tolerant varieties in the plant breeding program. Keywords: copper toxicity, low land rice, rice growth and production, water quality

Abstract

Chitinase and peroxydase are important bioactive proteins or are specific enzymes that are related to plant resistance to pathogens. The aims of the research were to analyze the chitinase and peroxidase activities of crude protein extract from calli, stem, leaves and roots of T. cucumerinavar. anguina. In the first experiment, chitinase and peroxydase activities were analyzed from in vitro calli, leaves and roots obtained from 2-month-old of field grown plants. The media for calli induction were Murashige and Skoog medium with addition of 1 µM NAA + 1 µM BA, 2 µM NAA + 2 µM BA, 3 µM NAA + 3 µM BA, or 4 µM NAA + 4 µM BA. In the second experiment, the chitinase and peroxydase activities from crude protein extract of roots, stems and leaves were analyzed. The extracts were from 3-week-old seedling (less than a month), 1-month and 2-month-old plants. The first and the second experiment results showed that crude protein extracts of plant roots from the field grown plants had the highest chitinase and peroxidase activities. Stem of field grown plants had the similar level of chitinase activities with the plant roots. Chitinase activities of in vitro calli were not significantly different from those of plant roots so that it could be used as an alternative for plant roots in studying chitinase from T. cucumerinavar. anguina. Chitinase activities in crude protein extracts of roots appeared constant whereas peroxidase tend to increase with plant age. Keywords: calli, enzyme activities, leaves, roots, stem

Abstract

The objective of this experiment was to identify the growth and production of rice varieties as responses to drought period in low land rice system. Rice plants were grown under plastic house in plots separated by massive walls. Drought periods were treated as main plots, i.e. water was supplied during 3, 6, and 9 weeks after rice transplanting, and control (cultivation without drought treatment). Rice varieties were used as sub plots, consisted of IR64 and Ciherang (low land improved varieties), IPB-3S (new plant type), Menthik Wangi (an aromatic local low land rice), Rokan (a hybrid rice), Way Apo Buru (amphibian type), Jatiluhur and Silugonggo (up land type). Our results showed that drought periods suppressed plant height, tiller number, spikelets length, weight of 1,000 grains, shoot dry weight and harvest index, and increased number of empty spikelets. Interaction between drought periods and rice varieties significantly affected productive tiller number, percentage of plants to flower, and grain weight per hill. Jatiluhur, Ciherang and Way Apo Buru still gave relatively high yields under drought stress indicated that those varieties were relatively tolerant to drought stress; Silugonggo and IPB-3S had medium tolerance to drought stress; IR64, Menthik Wangi and Rokan were the most sensitive varieties. Keywords: drought stress, drought tolerant, improved variety, local variety

Abstract

The objectve of this research was to obtain the best materials composition and adhesive of organic pot for forest trees seedling production. Organic pot strength was evaluated by testing the strength of rupture elasticity and elasticity stiffness of each composition. The bioassay testing used Completely Randomized Design with factorial pattern, consisting of two factors, (1) basic raw materials of the pot (used newspaper, litter and compost) and (2) the type of adhesive (control, tanin and starch). The results showed that the adhesive starch gave higher strength, whereas adhesive tannin gave higher stiffness as compared to control. Results of bioassay showed that the mixture (50:50 v/v) of basic materials of used newspaper and compost (KKK) which were glued with tannin, produced the best results for height and diameter increament with the value of 35.85 cm, 0.31 cm respectively and biomass value of 0.99 g after 12 weeks of planting. The highest level of damage in organic pot with basic raw materials KKK without adhesive was 47.6%, whereas lowest level of damage in organic pot with basic raw material used newspaper (KK) with tannin addhesive was 2.0% after 12 weeks in the nursery.Keywords: adhesive, Gmelina arborea,organic pot, organic matter, nursery,

Abstract

Light use efficiency is a crucial parameter in plant growth associated with accumulation of energy interception. Nitrogen and phosphorus deficiency reduce leaf area index (LAI) and specific leaf nitrogen and phosphorus (SLN and SLP) content and reduce efficiency of light intercepted by plant canopy structure. This research was conducted in Kebun Bunga Mayang PTPN VII, North Lampung Regency, Lampung Province (04050’S, 104052’E, 38 m above sea level) from July 2008 to September 2009. Treatments were distributed in the field under a randomized complete block design factorial with three replications. The increase in nitrogen fertilizer (N) improved sugarcane light use efficiency. The light use efficiency of the sugarcane plants fertilized with 225 kg N ha-1 was 2.29 g MJ-1 at maximum stem phase. On the contrary, the increasing of phosphor (P) fertilizer did not affect light use efficiency but increased stem dry matter at maximum seedling phase or about 3 month after planting (3 MAP), at maximum stem phase (9 MAP), and at harvest (11 MAP); total dry matter at seedling phase (5 MAP) and at maximum stem phase (9 MAP). Nitrogen did not interact with P in affecting light use efficiency. Keywords: fertilization N and P, interception radiation, light use efficiency, sugarcane

Abstract

This research was conducted to determine peanut cultivar differences in sink and source sizes as represented by vegetative growth and yields. Two sets of experiments were conducted at Bogor Agricultural University farms, Sawah Baru and Cikarawang (06o33’, S, 106o45’E, 250 m altitude). Planting was conducted on June 12 and June 20, 2007 using 20 local and national cultivars in each location. Both experiments used randomized complete block design with three replications. Data were analyzed using correlation and regression analysis. Size of experimental unit was 1.6 m x 4.0 m, with planting density 125,000 plants ha-1. Urea, SP36 and KCl were applied at planting date in the rate of (kg ha-1) 45 N, 100 P2O5 and 50 K2O. Four stages of plant growth were studied: 25 days after planting (DAP); 6 weeks after planting (WAP); 10 WAP (pod filling) and 14 WAP (harvest). Five plants were sampled at 25 DAP, two plants at 6 WAP, 10 WAP and 14 WAP, and separated into leaves, stems, roots and pods. The average yield of two experimental stations showed that Biawak cultivar had the highest yield due to relatively higher aboveground dry weight (source), pod filling percentage and maximum number of gynophor+pods (potential sink). Jepara cultivar had the lowest yield due to low pod filling percentage and potential sink, although its source was considered to be in the medium category. Above ground dry weight at 6 and 10 WAP had close relation with Crop Growth Rate (CGR) during 25 DAP-6 WAP and 6-10 WAP, and the higher CGR during those periods were more related to leaf area index than to single leaf photosynthetic capacity. Keywords: crop growth rate, pod filling percentage, leaf area index, single leaf photosynthetic capacity

Abstract

The research objective was to study the agronomic and physiological characteristics of red chilli (Capsicum annuumL.) varieties under waterlogging stress. These studies were conducted at two locations: in Palembang, South Sumatra, from February to August 2010 and in Bogor in West Java, from September to November 2010. Experiments in Palembang was using split plot design with three replications. The main plot was waterlogging treatment for 1, 2, 3 and 4 days. The subplot was red chilli varieties: Kiyo F1, Riawan, Ferosa, Bravo F1 and Laris. Experiments in Bogor was conducted without the use of experimental design; the same plant varieties were waterlogged for 2 and 4 days. The results showed that waterlogging caused root damages on all varieties. Kiyo F1 had better agronomic characters and high levels of tolerance than other varieties. The content of ethylene in all varieties increased with increasing time of waterlogging, except for Laris. In all varieties both leaf chlorophyll and tissue N content tend to decline with the increase in waterlogging duration. However Bravo F1 experienced an increase in the chlorophyll content whereas Kiyo F1 had an increase in N in the plant tissue. Keywords: agronomic character, physiological character, red chili, waterlogging

Abstract

The objective of the research was to determine the roles of fertilizers application in improving rice ratoons. Statistical design used was a factorial randomized complete block design with three replications. The first factor was three levels of fertilizer rate (kg ha-1) i.e. 5 N + 27 P2O5; 45 N + 30 K2O; and 27 P2O5+30 K2O. The second factor was rice genotypes, i.e. Cimelati, Hipa-5 and Rokan varieties, and two lines of rice i.e. IPB106-7-47-DJ-1 and IPB106-F-8-1. The growth and production characters of main crops and ratoon were observed. The results showed that both genotypes and rates of fertilizer affected yield of ratoon. Following application of (kg ha-1) 45 N + 27 P2O5 three genotypes produced the highest ratoon, i.e. IPB106-7-47-DJ-1 and IPB106-F-8-1 lines and Rokan variety. Cimelati and Hipa-5 varieties produced higher number of ratoon with fertilizer rate (kg ha-1) 45 N + 30 K2O. Ratoon production of all genotypes ranged 38.1-56.6% of the main crop. This study clearly demonstrated that N, P and K fertilizer had important roles in increasing yield and yield components of rice ratoon. Keywords: fertilizer, productivity, rice genotypes, rice ratoon

Abstract

The objective of this research was to study the effect of bokashi livestock on the growth and yield of tomatoes. The experiment was conducted in Bandar Lampung from October 2009 until February 2010. The experimental design was randomized complete block design with 3 replications. The treatments were: control; inorganic fertilizers at a recommended rate of (kg ha-1) 135 N, 75 P2O5, and 110 K2O (RR); chicken manure bokashi + RR; chicken manure bokashi + 50% RR; cow manure bokashi + RR; cow manure bokashi + 50% RR; sheep manure bokashi + RR; sheep manure bokashi + 50% RR; horse manure bokashi + RR; horse manure bokashi + 50% RR. Each bokashi treatment was applied at the rate of 20 ton ha-1. The result of experiment showed that chicken manure bokashi was the best among bokashi livestock. The application of 50% RR combined with chicken, cow, sheep or horse manure bokashi gave a higher yield than treatment with inorganic fertilizer at recommended rates. These results demostrated that the application of bokashi livestock could potentially reduce the use of inorganic fertilizers while maintaining higher yield. Keywords: animal manure, inorganic fertilizer, bokashi livestock, tomatoes
