Efforts to produce wheat in Indonesia need to be supported by the availability of cultivation technology suitable for agro-climate conditions in Indonesia, including the use of proper population density and fertilization dosages, which are fundamental for obtaining maximum yields. This study was aimed to determine ideal population density and dosage of urea for optimum grain yield of wheat in Lombok Island. The experiment carried out at Aik Bukak, Central Lombok at elevation of 400 m asl, to observe the growth and yield of two varieties of wheat, Nias and Gladius, with 4 plant population densities (133, 160, 200, and 250 plants m-2) and 3 dosages of urea fertilization, 200, 300, and 400 kg ha-1. Data from this study indicated that Lombok Island has the potential for growing wheat with quite dense population density of 250 plants m-2. This density yielded higher, 1.74 tons ha-2, due to the increased number of kernel per unit area without reducing individual kernel weight. The use of urea 300 kg ha-1 exhibited the best growth and yielded 1.32 tons ha-2.Keywords: fertilization, population density, wheat varieties

This study aimed to determine the change in total genetic diversity after eight cycles of mass selection using a technique of selection index for yield, fresh dry matter, and weight of dry harvested cob, and to find out the average of these three characters compared to the initial population. This experiment was carried out at Pringgabaya District, East Lombok Regency using Randomized Block Design (RBD) with 11 treatments, namely eight selected populations, initial populations and two hybrid varieties. Each treatment was replicated 3 times, resulted in 33 experimental units. Data obtained were analyzed using analysis of variance at 0.05 levels. Variance of phenotype is obtained from the variety of samples; while the environmental variance is defined as the average variance of the two hybrid phenotypes. Genetic diversity is obtained from the variety of phenotypes of each population minus the environmental diversity. F-test of 0.05 was performed to find out whether the genetic diversity of the eighth cycle population is the same or different to that of the genetic diversity of the initial population. The average between the initial population and the eighth cycle population was tested using the HSD-test at 0.05 levels. The results showed that the total genetic variation in the population from the eighth cycle selection for yield, harvested dry weight of cobs, and fresh dry matter of maize were smaller than the genetic diversity of the initial population. The average yield, harvested dry cob weight and fresh dry matter weight of population of the eighth cycle selection are higher than the initial population

This study aims to determine the average leaf angle, harvest age and yield of F1 from cross-hybrid composite; heterosis value and knowing the maternal effect of these three traits on maize. The experiment was carried out in technically irrigated rice fields from November 2019 to February 2020. The design used in this experiment was a randomized block design with two replications. The treatment was 28 F1 as a result of crossing P8IS vs NK212 and P8IS vs NK7328 and their respective reciprocal crosses. The experimental data were analyzed by means of analysis of variance and further tested with the LSD test at the 5 percent level. Heterosis values were calculated on the basis of the parents whose scores were higher (High Parent Heterosis). The t test at the 5% level was used to determine whether the maternal effect was significant. The results showed that the mean leaf angles of F1 lines from crosses and reciprocal P8IS vs NK212 were the same as the two parents; whereas the P8IS vs NK7328 cross is different. The reciprocal of cross number 13 (P8IS vs Nk7328 /R13) has smaller leaf angle than P8IS and is the same as the leaf angle of NK7328. The yield of the F1 lines from the two types of crosses was the same as each of the two parents; however, there was a tendency for an increase in yield compared to P8IS for most of the F1 lines. There was a change in leaf angle properties, harvest age and yield of F1 lines compared to one of the best parents with heterosis values are negative and positive with variations from 0.00 to 65.70 percent. Coefficient of correlation between heterosis with the average value of traits was classified as strong for the harvest age; moderate for yield and weak for leaf angle. These three traits in the two types of crosses showed no maternal effects. Smaller leaf angle, super early harvest age and higher yield, are possible to be obtained from the lines of both crosses.

This study was aimed to determine the average of leaf angle, yield and harvest age of each F2 line compared to the two parents respectively. In addition, we also want to evaluate the coefficient of genetic diversity and heritability of the three traits. The experiment was designed in a randomized block design with a total treatment of 20 populations, namely 16 F2 lines and 4 parents. Each treatment was repeated 3 times, so that 60 experimental units were obtained. The experimental data were analyzed by analysis of variance at the 5 percent significance level and further tests using the Least Significant Difference at the same significance level. The results showed that the F2 P8IS x T1NK7328 (R16), F2 P8IS x T1NK7328 (R18) lines, and the F2 P8IS x NK212 (R4) lines, had leaf angles same as each parent of the first hybrid/hybrid offspring (T1NK7328 and NK212) and smaller than the Sinta Unram. The harvest time of the three F2 lines was classified as super early. Yield (weight of dry seeds per plot) of F2 P8IS x T1NK7328 (R16), F2 P8IS x T1NK7328 (R18) lines, were the same as both parents and F2 P8IS x NK212 (R4) lines, higher than Sinta Unram; but the same as the hybrid parent (NK212). Coefficient of genetic diversity of yield is high; medium for harvest time and low for leaf angle. Heritability in broad sense is classified as high, obtained at harvest time and yield; while the heritability of leaf angle is low. The three F2 lines can be used as basic population material for subsequent breeding activities. Key words: hybridization; Sinta Unram; yield; leaf angle

ABSTRAK Peranan actinomycetes endofit sebagai agen pengendali hayati telah banyak diketahui, terutama dalam menghambat jamur pathogen tanaman, tetapi perannya dalam menekan infestasi nematode masih sedikit diketahui. Tujuan penelitian ini untuk mengamati potensi actinomycetes endofit dalam menghambat nematoda parasit tanaman Meloidogyne javanica. Ekstrak methanol dari 42 strain actinomycetes endofit diuji secara in vitro untuk mengamati efeknya sebagai nematisida pada root-knot nematode (Nematoda puru akar) M. javanica. Metabolit dari 84% strain-strain yang diuji secara signifikan menurunkan motilitas nematoda, sedangkan 21% menyebabkan kematian juvenile. Metabolit dari Streptomyces somaliensis PM143 dan Streptomyces peruviensis EN26 menunjukkan efek nematostatic tertinggi dengan tingkat penurunan motilitas M. javanica yang signifikan, berturut-turut 54% dan 44%. Evaluasi selanjutnya dilakukan in planta untuk menguji aktifitas nematisida dari 8 strain terpilih representasi dari berbagai tingkat aktifitas nematisida secara in vitro pada tanaman mentimun (Cucumis sativus L.) sebagai crop model. Walaupun jumlah nematode yang memasuki system perakaran tidak terpengaruhi, tetapi S. somaliensis PM143 dan S. peruviensis EN26, juga S. somaliensis PM349 mampu menghambat perkembangan stadia nematode dan menurunkan jumlah puru akar (root galls) pada tanaman mentimun. ABSTRACT The role of endophytic actinomycetes as biocontrol agents has been studied, especially in inhibiting fungal plant pathogens. However, little is known on their role in suppressing nematode infestation. Therefore, the main aim of this study was to observe the potential of endophytic actinomycetes in suppressing plant-parasitic nematodes Meloidogyne javanica. Methanol extracts of 42 strains of endophytic actinomycetes were screened in vitro to determine their nematicidal effects on the root-knot nematode M. javanica. Metabolites from 84% of the strains tested significantly reduced the motility of nematodes, while 21% caused juvenile mortality. Metabolites of Streptomyces somaliensis PM143 and Streptomyces peruviensis EN26 showed the highest nematostatic effect in vitro, with a significant reduction in motility of M. javanica by 54% and 44%, respectively. Further evaluation was carried out in planta to test the nematicidal activity of eight strains representing various level of nematicidal activity in vitro using cucumber (Cucumis sativus L.) as crop model. Even though the number of nematodes invading the root system was not affected, S. somaliensis PM143 and S. peruviensis EN26, as well as S. somaliensis PM349, were able to inhibit nematode growth and reduce the number of root galls in cucumber plants.
