Abstract

Human activities in seeking agricultural lands, has change the traditional agricultural system into intensive cultivation system. One effort to minimize intensive agriculture system is the use of natural enemies to control pests. Habitat management should be implemented by creating habitat favored by natural enemies. This research aims to determine the spatial and temporal distribution of natural enemies of wild plants: Mimosa pudica, Vernonia cinera, Marsilea crenata, and Pistia startiotes on agricultural land. This research was conducted in March-April 2010 in Malang Sawojajar farmland. Plants placed in the corner field (refugia areas), visiting insects was observed starting from refugia areas and two meters away from the refugia area. Observations of insect use the "visual control" metode. The results showed that natural enemies visiting to the refugia areas were 6 orders (15 families): Coleoptera, Odonata, Aaraneae, Hymenoptera, Diptera, and Orthoptera. Not all natural enemies have spatial and temporal distribution, only 9 families who indicate a pattern spatial or and temporal distribution. Overall, natural enemies do not show any significant spatial pattern (F> 0.05), but indicate a temporal pattern (F

Abstract

This study was conducted to evaluate the heritability, heterosis, and correlation among firmness, total soluble solid (TSS), and color in the F1 hybrids between two day-neutral (DN) and six short-day (SD) cultivars. The firmness of DN cultivars and the sweetness of SD cultivars were considered as a criterion in choosing parent cultivars. Parents and eleven F1 progenies were grown in completely randomized block design. Heritability of TSS, color (a*: opponent channel between red/magenta and green), and firmness was 0.67, 0.55, and 0.49, respectively. Most of the DN × SD hybrids had higher firmness and TSS than the crossing of SD × SD and DN × DN, respectively. In the DN × SD progenies, all heterosis values of TSS and most of heterosis of firmness were positive and negative, respectively. The genetic advance of TSS was higher than firmness. ‘DNKW002’ was a better donor for firmness and can be used as female parent in producing DN cultivar with high TSS. Correlation between firmness and TSS was negative, hence the simultaneous selection was recommended. Principle component analysis (PCA) based on characteristics indicated three groups: group of DN parents and hybrids of DN × DN, group of SD parents and SD × SD hybrids, and group of DN × SD and SD × DN hybrids. Additional key words: firmness, total soluble solid, heritability, PCA

Abstract

Current research was conducted with the objectives to identify the utmost traits that may be beneficial for the higher productivity of the grains on high protein content genotypes lines by path coefficient. Path coefficient can define coefficient correlation directly and indirectly to gain information about nature relationship between yield component and protein content to grain yield. Research material consisted of 61 selected plants from G39×Ciherang and 66 selected plants from Mentik Wangi×G39 at F4 generation. Plants were planted in Banyumas in May 2011. Number of panicles per plant, panicle length, 1000 g of grain weight, percentage of filled grain per panicle, protein content, and grain yield were correlated by using Pearson correlation and were followed by path coefficient. Number of panicles per plant, panicle length, 1000 g of grain weight, percentage filled grain per panicle, and protein content were used as dependent variable, while grain yield was used as independent variable. The result showed that protein content in both populations was not correlated with all yield components. The numbers of panicles, followed by panicle length, had highest positive direct effect to yield. The number of panicle was a positive mediator variable to yield from another variable.Keywords: correlation, direct effect, indirect effect, mediator variable, path analysis

Abstract

Gamma irradiation to induce mutation in plant has been used intensively since several decades ago.  On maize, 275 Gy gamma irradiation have been known to increase genetic variability indicated by their morphological variation.  Identification on genetic changes by molecular technique is important to answer whether there is mutation happening on DNA level of the plants.   The objective of this research was to identify RAPD marker polymorphism on gamma irradiation mutants compared to their parents.  The initial step of the research was to select random primers could positively amplify the maize DNA.  The result showed that selection on 60 random primers yielded 15 primers that positively amplified the maize DNA.  Amplification on both mutants and their parents by those 15 selected primers indicated that only 5 primers yielding polymorphism between mutants and their parents.  Polymorphisms on mutant G1, G3 and G6 were detected on one locus, meanwhile on mutant G7, G8 and G9 were on two loci.

Abstract

Research to study the effect of application of rock phosphate (RP) enriched with SP36 to soybean on Ultisol was conducted at ILETRIs' green house from July to October 2008. Treatment consisted of combination of rock phosphate from Lamongan and Bojonegoro at rates of 162 kg P2O5/ha with three rates of SP36 (0, 9, 18 and 27 kg P2O5/ha). The treatments were arranged in randomized complete block design and replicated three times. The result showed that application of RP from Lamongan and Bojonegoro to Ultisol Lampung at rates of 162 kg P2O5/ha increased soil pH by 0.3 and 0.5, available P (Bray 1) by 400% and 823% respectively compared to check.Highest soybean yield was attained by application of RP from Lamongan combined with SP36 at rates of 18 kg P2O5/ha or RP from Bojonegoro combined with SP36 at rates of 9 kg P2O5/ha which yielded 4.98 and 5.21 g/pot respectively. This result indicated that RP from Lamongan and Bojonegoro can be applied directly as P fertilizer for soybean in acid soil, and combining them with SP36 will increase their effectiveness.Keywords: rock phosphate, SP36, soybean, ultisol

Abstract

Physical characteristicsare among soil propertiesaffecting the susceptibility to erosion.  Determination of physical characteristics of Ultisol was aimed to evaluate the dynamics of soil properties as well asthe impact on soil erosion and runoff (RO) during soybean cultivation in wet tropical area.  Soybean was planted within erosion plots (18 m2)  at 25% slope in UltisolLimauManis (having > 5000 mm annual rainfall).   Soil samples for physical properties (soil texture, bulk density, total pore, permeability, aggregate stability,and organic carbon) as well as amount of RO and soil loss were analyzed at 5 different times (stages) during the cultivation.  The results showed that there was fluctuation in physical properties of Ultisol during the cultivation. Likewise, the amount of runoff and soil loss also changed during the study.  Among the physical properties analyzed, the aggregate stability index of the soil highly correlated to the amount of RO (R2=0.73) and soil loss (R2=0.94).  Amount of RO and soil loss was controlled by soybean development at the average rainfall intensity ≤ 36 mm/day, but not at rainfall intensity >36 mm/day.  It is suggested not to open heavily clayey-low OC soils for seasonal crop farming during rainy season in wet tropical area. Keywords: soil physical properties, Ultisol, erosion,runoff, soybean cultivation

Abstract

The objective of this study was to characterize salak of local varieties and their hybrids. The fruits characterized were taken from plants that were grown in October 2004. The results revealed that fruits ³ 61 g were mostly produced by hybrids, in which one of their parents was Mwr or Ph. Fruits with flesh thickness ³ 0.85 cm were mostly yielded from Sdp, Sdm, and hybrids where one of their parents was Sdp or Mwr. While fruits with edible portion ³ 65.0% were mostly yielded from Sdp, Gp, and hybrids where their female parents were Mwr, Ph, and Sdp. Fruits with small seeds (≤ 3.0 g) were observed on Gp, whilst those with big seeds (≥ 7.0 g) were on Sdm, Sdm-Sj and Sdp-Sj. Hybrids from the female of Ph and Sdp mostly gave sweet taste (TSS ≥ 20º Brix). Mwr x Sdp crossing produced non-astringent fruits, while Ph x Java (K, M, Mj), Sdp x Sjg and some Sdp x Mwr crossing as well as Mwr produced astringent fruits. The four superior characters, namely fruit ≥ 61 g, flesh thickness ³ 0.85 cm, edible portion ≥ 65%, and TSS ≥ 20º Brix were found in Mwr-Sp-8, Sdp-Sj-8, and          Ph-M-7. Fruits produced by Mwr-Sp-8 were not astringent, while those produced by Sdp-Sj-8 and Ph-M-7 were astringent. These findings suggest that the selection of parent can play an important role in improving the varieties of salak. Keywords: salak, characterization, variety, hybrid, fruit
