Abstract

Identification of Physiological Cooking Markers for Cucumber (Cucumis sativus L.) Seed Harvest. Cucumber (Cucumis sativus L.) has a wide adaptability to the environment. Cucumber production in Indonesia has decreased every year. The availability of quality seeds is one of the important factors in increasing the productivity of cucumber plants. This study aims to identify physiological ripening markers, especially in cucumber fruit. This study used a one-factor randomized block design method with 4 levels of treatment at harvesting age of cucumbers, namely 24, 27, 30, and 33 days after flower blooming. The variables observed in this study were; a) identification of fruit and seed maturity markers; 1) fresh weight of fruit (g), 2) fresh weight of 100 seeds (g), 3) oven dry weight of 100 seeds (g), 4) seed moisture content (%), and 5) fruit color development; b) testing of seed quality; 1) seed germination (%) and 2) seed germination vigor (%).The results showed that the right harvest time based on the character of the fruit and seeds to produce quality seeds for cucumber plants was 27 days after the flowers bloom. The character of the fruit at that time was shiny green with a yellow tinge and reached the maximum fresh weight, while the character of the seeds at that time was bright yellow seeds, with a fresh weight of 100 seeds was 3,95g and an oven dry weight of 100 seeds was 1,51g reaching the maximum weight. And seed moisture content at the age of 27 with the lowest percentage. The quality of cucumber seeds harvested when physiologically ripe was obtained with the highest average values such as seed germination (93.17%) and simultaneous growth vigor (81.83%).

Abstract

Effect of PGPR (Plant Growth-Promoting Rhizobacteria) Application on Growth and Yield of Local Rice (Oryza sativa L.) Varieties in Jatiluwih Village. The decline in local rice production in Jatiluwih Village needs to be overcome to meet the needs of the community, one method that can be used is the application of PGPR. This study aims to determine the differences in the effect of cultivation with PGPR application and without PGPR application on the growth and yield of local rice varieties and to find out which local rice varieties shows the highest yields. This study used a paired experiment that compared cultivation with and without PGPR application on four local rice varieties, namely Cicih, Cendana, Ketan and Mansur varieties. The results of the analysis showed that the application of PGPR in the cultivation of Jatiluwih local rice varieties was able to increase the average value of plant height, number of leaves per clump, leaf chlorophyll content, total number of tillers per clump, number of productive tillers per clump, panicle length, total grain per panicle, good grain per panicle and yield, respectively 1.66%, 16.89%, 5.97%, 18.79%, 15.65%, 11.54%, 25.65%, 30.55% and 10.53% when compared to cultivation without PGPR application. The Local varieties of Jatiluwih rice that showed the highest yield when compared between cultivation with PGPR application and without PGPR was the red rice variety Cicih, which increased by 19.27% ??from the previous 5.45 ton/ha to 6.50 ton/ha, while in Cendana variety only increased by 5.76%, Kentan variety increased by 11.33%, and Mansur variety increased by 5.57% after PGPR was applied.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh beberapa metode perendaman terhadap pematahan dormansi serta metode yang mampu mempercepat pematahan dormansi benih padi varietas Ciherang. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap satu faktor yaitu metode perendaman dengan 5 taraf perlakuan: metode tanpa perendaman (P0), metode perendaman menggunakan air bersuhu 30 °C selama 24 jam (P1), metode perendaman menggunakan air panas dengan suhu awal 60°C selama 24 jam (P2), metode perendaman menggunakan larutan GA3 dengan konsentrasi 0,5 ppm selama 24 jam (P3), dan metode perendaman menggunakan larutan KNO3 dengan konsentrasi 3% selama 48 jam (P4) dengan lima kali ulangan. Penelitian dilaksanakan di Laboratorium Pemuliaan Tanaman dan Teknologi Benih Fakultas Pertanian Universitas Udayana pada bulan September 2020 sampai November 2020. Hasil penelitian menunjukkan metode perendaman berpengaruh sangat nyata terhadap variabel daya kecambah (%), potensi tumbuh maksimum (%), intensitas dormansi (%), dan kecepatan berkecambah (%/etmal), serta berpengaruh nyata terhadap pertumbuhan jamur benih (%). Perlakuan P3 mampu mematahkan dormansi benih padi selama 5 minggu pengamatan dengan nilai daya kecambah tertinggi (95,16%) dan memperoleh nilai intensitas dormansi terkecil (4,56%) lebih baik dibandingkan dengan perlakuan P0 tanpa perendaman (kontrol) memperoleh nilai daya kecambah sebesar (7,76%) dan nilai intensitas dormansi sebesar (89,52%). Kecepatan berkecambah tertinggi diperoleh pada perlakuan P3 dan P4 yaitu masing-masing (6,08%/etmal) dan (3,35%/etmal).
