Desa Tanak AwuÂ adalah salah satu desa di Kecamatan Pujut-Kabupaten Lombok Tengah dan merupakan tempat Bandara Internasional Lombok. Sumber mata pencaharian penduduk Desa Tanak Awu adalah sebagai petani lahan kering meskipun produktivitas dan pendapatan dari sistem pertanian ini rendah sehingga mengakibatkan kemiskinan. Kemiskinan dan rendahnya produktivitas pertanian di desa ini mengakibatkan kurangnya kemampuan pengadaan modal untuk aplikasi input pertanian secara optimal dan untuk pengupahan tenaga kerja. Namun, Â berdasarkan hasil penelitian yang terkait dengan model pemberdaayaan kelompok perempuanÂ yang disuluhkan pada kegiatan ini ditemukan kondisi kontra-produktif tradisi patriarhi yang dianut masyarakat. Kelompok perempuan tidak bekerja di lahan pertaniannya, partisipasinya sebatas penyedia makanan untuk pekerja liar keluarga. Secara kultural peran mencari nafkah terbeban mutlak di kelompok laki-laki dan potensi produktif perempuan terpendam meskipun kekurangan tenaga kerja untuk mengelola usahataninya. Untuk itu, kegiatan pengabdian kepada masyarakat ini bertujuan memberdayakan potensi kerja kelompok perempuan melalui pengembangan kegiatan produktif-ekonomi yang selaras tradisi.Â Tradisi tersebut memilik potensi positip yakni tersedianya banyak waktu luang kelompok perempuan diantara aktivitas domestikasi dan disuluhkan untuk pengembangan sistem pertanian organik tanaman hortikultura dalam wadah polybag di halaman pekarangan. Sistem binaan ini selaras tradisi serta hemat lahan dan waktu pengelolaan sehingga lebih optimal perolehan produksi dan pendapatannya. Implikasinya adalah kelompok perempuan dapat berkontribusi secara ekonomi untuk membebaskan keluarganya dari kemiskinan.

ABSTRACTSuccessful castor (Ricinus communis L.) cropping depends on the reliability of production technique. Branching is a useful agronomic trait because infloresence developed at each branch’s terminal. Pruning is considered as an important technique for branching stimulation. This study attempted to elucidate the effect of main stem pruning on the yield of Beaq Amor local variety of castor (Ricinus communis L.) with short cultivation system. The experiment was conducted on dry land area of Amor-Amor, North Lombok, West Nusa Tenggara during February-July 2011 and was arranged in a single-factor randomized complete block design with three replications. The treatments were four types of pruning (i.e. no pruning, main stem pruning at 30 days after planting, 45 days after planting, and 60 days after planting). The results showed that the effect of pruning was significant on dry seed yield and was not significant on kernel oil content. Pruning at 30 days old and 45 days old plant yielded in the highest dry seed weight (374.9-387.8 g tree-1 or 943.0-974.3 kg ha-1) with oil content of 62.2%.Keywords: branching, canopy, dry seed, Ricinus communis L.

This study aimed to determine the efficacy of several varieties of maize at various rate of manure under drought condition on the dry land of North Lombok. The experiments were designed using split plot design, with manure rates (0, 5, 10, 15 and 20 t.ha-1) as the main plots, and five different maize varieties (P4IS, Gumarang, Lamuru, Sukmaraga and NK212 Hybrid) as subplots. The efficacy of several maize varieties were determined from the weight of dry seeds per plant. Experimental data were analyzed using analysis of variance (ANOVA) at 5 percent significant levels. The mean of each treatments was further tested using the Honestly Significant Difference (HSD) at the same level. The results showed that the highest yield of maize crop was obtained on Lamuru variety at rate of manure of 20 t/ha, ie 85.94 g.plant-1 or 6.14 t.ha-1. The yield of Lamuru variety is similar to that of Sukmaraga, but it is higher compared to P4IS, Gumarang and Hybrid of NK212.The highest yield of maize crop was obtained at rate of manureof 20t.ha-1.

The objective of the research is to investigate the selection response indirectly on the corn yield in dry land, and the yield improvements of yield due to seven cycles. The selection method used were mass selection with and without pollination controll. The method used to minimize environmental effect during selection was subdivided block that (subselection block divided into small plots). In each plot, there was 40 plants, and the number plants selected were 5 %. Randomized Completely Block Design was used to study the selection result. The data collected were analyzed using Analysis of Variance, and the difference between populations were tested using Least Significant Difference in 5 % significant level. The average of selection response per cycle every technique used was gained from polynomial regression coefficient among the characters observed with selection cycle The percentage of the corn yield improvement was gained from the difference between the seventh cycle and the base population, and then, substracted by the base population. The result showed that the response indirectly of mass selection with and without pollination controll were significantly linear, and the values were 47.88 and 72.80 g per plot, respectively. The yield improvements were 43.46 % and 79.21 %, respectively

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

This study aimed to determine the degree of additive variation and the dominant varietion of yield and fresh biomass and other properties and also to identify the narrow sense heritability of all observed traits. The research activity was carried out in two stages, namely making kinship with NC I and testing the results of the crosses. A total of 60 crosses were tested from 20 male parents. The design used for the crosses was a randomized block design with two replications. Each treatment (the result of crosses), planted in one row; each row contained 40 plants. The properties observed included plant height, number of leaves, fresh biomass weight, harvested dry ear weight, ear length, ear diameter, and yield. The data from the observations were analyzed by means of an analysis of variance with the model following the design of the NC I cross at the 5% ignificant level and continued with the estimation of the additive and dominant variants and the standard deviation of each of these variance evaluation. The results showed that the variety of additives was greater than the dominant variation, especially obtained in plant height, number of leaves, weight of fresh biomass per plant, ear length, and yield; on the other hand, the dry weight of harvested cobs and ear cobs had a smaller additive variety than the dominant variety. The heritability of narrow sense is high in fresh biomass weight and ear length; moderate on the number of leaves per plant, ear diameter, and yield; and classified as low on plant height and ear diameter. The increase in yield and fresh weight of the P8IS population should be carried out by further selection method.
