Abstract

Gerakan masyarakat hidup sehat (GERMAS) merupakan program pemerintah yang bertujuan untuk meningkatkan kualitas hidup manusia melalui kesadaran, kemauan dan kemampuan berperilaku sehat. Salah satu fokus kegiatan GERMAS adalah meningkatkan konsumsi buah dan sayur. Buah dan sayur merupakan produk hortikultura yang segar sehingga membutuhkan air yang banyak untuk memproduksinya. Desa Gumantar di Kabupaten Lombok Utara yang akan dijadikan Kawasan Pengembangan Tanaman Hortikultura, lahannya kebanyakan kering dan berpasir sehingga biaya produksi, khususnya air menjadi mahal. Oleh karena itu efisiensi penggunaan air harus ditingkatkan. Salah satu cara untuk meningkatkan efisiensi penggunaan air di lahan kering pasiran adalah dengan meningkatkan kandungan bahan organik tanah. Sumber bahan organik cukup berlimpah tersedia di wilayah tersebut, seperti biomassa tanaman jagung, kacang hijau, kacang tanah, melon, dan kotoran ternak. Permasalahannya petani belum memiliki pengetahuan dan teknologi untuk merubah secara cepat biomassa tanaman dan kotoran ternak menjadi bahan organik. Tujuan kegiatan ini adalah memberikan pengetahuan dan teknologi tentang penggunaan BioCompound untuk mempercepat proses dekomposisi limbah pertanian menjadi kompos untuk selanjutnya dijadikan bahan organik tanah. Di masa yang akan datang masyarakat desa Gumantar diharapkan menjadi lebih sehat karena mengonsumsi banyak buah dan sayur dengan terjadinya efisiensi dalam biaya produksi.

Abstract

The narrow-sense heritability and expected selection response are very important to be recognized in the F2 population of maize to determine the character to be selected. This study aimed to estimate the narrow-senseheritability and the expected selection response of quantitative characters in the F2 population. The experimental method used in this study was field experiments on dry land using pumping wells for irrigation. This was conducted from April to October 2022 in Amor-Amor Hamlet, Gumantar village, North Lombok district. The experiment was carried out in two growing seasons; namely: the first growing season was to establish kinship with NC1 and the second season was to test the results of crosses by used a Randomized Block Design (RBD). The number of treatments was 105; derived from 35 male parents. Each treatment was replicated 2 times, so there were 210 experimental units. Data were analyzed using analysis of variance (ANOVA); and then calculation of narrow sense heritability and response selection expectations was conducted. The results showed that the narrow sense heritability of all the quantitative characters observed was low, while the selection response of the biomass weight per plant was high; Plant height, leaf angle, and dry cob weight per plant were moderate and other characters were low. Fresh biomass weight per plant can be used as a selection criterion for improving the stay-green character. Yield can be improved through enhancing dry cob weight per plant. Keywords: corn; heritability; response of expected selection and dry land.

Abstract

Pineapple (Ananas comosus L. Merr) is one of the significant yields and the fundamental product created in Okinawa since it is appropriate climatic condition for pineapple improvement. seeds. This study intends to decide the quantitative characters of seedlings from stem engendering of pineapple (Ananas comosus L. Merr) stem cutting on two assortments in Okinawa, Japan. The review was led in December 2022 at Yagaji Island Nursery, Okinawa, Japan. A quantitative descriptive approach was used in the research, and random sampling was used to select 15 seedlings from each variety based on their age, starting at 60 HST, 90 HST, and 120 HST, for a total of 90 samples. Each seed test was noticed in view of boundaries set each month, in particular seedlding level, stem width number of leaves and. Research information were dissected utilizing basic measurement examination. The mean of each character was tried utilizing the T-test at the 5% level and the connection between's qualities was broke down utilizing the r-test at the 5% level. The outcomes showed that there were contrasts in quantitative characters of the two assortments, specifically the N67-10 assortment showing taller seedlings, more number of leaves and bigger stem at the three periods of perception, with the exception of 60 days for stem distance across and 120 days for seedling level. With a range of 0.44-0.77, the phenotypic correlation between characters is real.

Abstract

Selfing is the initial step to form hybrid varieties. Selfing has been carried out for four generations and 29 S4 lines have been obtained. All lines have been tested for their tolerance level to drought stress in dry land. The purpose of the study was to determine the tolerance level of S4 lines of corn plants to drought stress in dry land. Experimental methods with field trials were used for the test. And the correlation between characters and ISC values. The design used was a randomized block design at each stress level. Determination of the tolerance level used the observation parameter of the results (dry seed weight per plant) under mild stress conditions and normal conditions. The tolerance level to drought stress was measured from the Stress Sensitivity Index (ISC) value. The results showed that three S4 lines were tolerant to drought stress, namely lines S4.7, S4.15 and S4.24. Nine S4 lines have moderately tolerant category, namely lines S4.1, S4.3, S4.8, S4.12, S4.13, S4.14, S4.21, S4.26 and S4.29; the rest are classified as sensitive. The yield have a high negative correlation with the ISC value; the weight of dry cobs harvested per plant has a moderate negative correlation. The three tolerant lines can be used for the formation of S5 lines.

Abstract

The reason for the low productivity of cashew in the Indonesian province of West Nusa Tenggara is that they are never cared for and the land between the cashew tree rows is not intensively cultivated. The first factor is the type of organic fertilizer: cow, horse, and chicken manure; a mixture of cow + horse manure, cow + chicken manure, and horse + chicken manure. The second factor is the dosage ratio of organic fertilizer: 35 tons + NPK 0 kg ha-1, 25 tons + NPK 250 kg ha-1, 15 tons + NPK 500 kg ha-1, and 0 tons + NPK 750 kg ha-1. The application of organic fertilizer from a mixture of cow and chicken manure at a dose of 15-25 tons + NPK 250-500 kg ha-1 significantly increases soil fertility status and reduces the rate of soil erosion. When applying the best type of organic fertilizer, the dosage ratio of 35 tons + NPK 0 kg ha-1 and 0 tons + NPK 750 kg ha-1, the effect is not significantly different for all parameters. Applying a dose of 15 to 25 tons per hectare can replace the role of NPK fertilizer by 33.33 to 66.67% of the 750 kg per hectare dose and significantly increase the cattle breeding capacity of cashew plantations by up to 5,875 livestock unit hectare-1 season-1
