Abstract

The requirements for rice as the staple food in Indonesia tends to increase every year along with the increase in population. As anticipation, an alternative that can be taken is to increase the productivity of carbohydrate-producing crops as the main non-rice food source on dry land. Sorghum is a versatile plant that can be used as a source of food, animal feed, and industrial raw materials. The purpose of this study was to determine the production of 3 varieties of sorghum to reduce the dose of NPK fertilizer. The research was conducted in Sumber Agung Village, Plosoklaten, Kediri Regency in May-August 2020. The research used a factorial randomized block design with the first factor being 3 varieties of sorghum, namely Kawali, Numbu, and Suri 4, the second factor was the dose of NPK fertilizer, which was 100%, 75 %, 50%, 25%, and 0%. The results showed an interaction between sorghum varieties and fertilization doses. Kawali variety only produces maximum if fertilization is 100%, Numbu variety still produces maximum at 50% fertilization and Suri 4 variety can still produce maximum at 25% fertilization.

Abstract

Sweet corn provides high profit relative when cultivated properly (Sudarsana, 2000). One of the efforts that can be taken in producing quality sweet corn is the determination of the dose of organic fertilizer “Petroganik and proper biofertilizer. The alternative to resolve the problems of soil with low fertility is by way of utilization of arbuscularmycorrhiza fungi (CMA). This study purpose: 1) to know the interaction dose of organic fertilizer “Petroganik” and mikoriza on growth and production of sweet corn; 2) to know the effect of dose of organic fertilizer “Petroganik” and mikoriza on growth and production of sweet corn. The study was conducted in January - March 2017, in Kalen, Sidomulyo Village, District Wates, Kediri Regency. This study used a factorial randomized block design (RAK), consisting of two factors and three repetitive. The results of the study concluded that: 1) sweet corn was inoculated mycorrhiza fungi was not significantly different from the treatment combination with the addition of dose of “Petroganik” fertilizer; 2) on plant growth the overall treatment had no real effect and no interaction occurred.

Abstract

Chili is an important horticultural commodity in Indonesia. However, its production is still not optimal because there are not many superior seeds available, which causes low productivity. One solution to this problem is to improve planting material (seeds) by a plant breeding program through a hybridization process. Crossing different types of chili requires the right time to increase the chances of success. The purpose of this study was to determine the effectiveness of crossing three genotypes of chili (two introduced and one local). The study was carried out with a factorial randomized design. The first factor was a combination of crosses of three parents, namely Sweet Italian, Garda and Katokkon by dialel crosses. The second factor was the time of crossing, namely at 04.00, 05.00, 06.00, 07.00, 08.00. The results of the analysis showed that the combination of parents had an interaction with crossing time in increasing the dsuccess of the crosses. Each parent combination hah a specific time for crossing. If the female parent was Sweet Italian, the time of crossing early in the morning (low temperature) was more optimal, which was between 04.00-07.00. For Katokkon×Garda crosses and their reciprocals, the percentage of successful crosses increased if it was done at 06.00-08.00. None of the crosses between Garda×Sweet Italian were successful or were entirely lethal. Keywords: chili, crossing time, dialele , introduction genotype ABSTRAK Cabai merupakan komoditas hortikultura yang penting di Indonesia. Namun produksinya masih belum optimal karena belum banyak tersedia benih unggul, yang menyebabkan rendahnya produktivitas. Salah satu solusi masalah tersebut adalah dengan perbaikan bahan tanam (benih) melalui program pemuliaan tanaman dengan proses persilangan (hibridisasi). Persilangan cabai yang berbeda jenis memerlukan waktu yang tepat untuk dapat meningkatkan peluang keberhasilannya. Tujuan penelitian ini adalah untuk mengetahui efektivitas waktu persilangan tiga genotipe cabai (dua introduksi dan satu lokal). Penelitian dilaksanakan dengan rancangan acak kelompok faktorial, Faktor pertama adalah kombinasi persilangan dari tiga tetua, yaitu Sweet Italian, Garda dan Katokkon secara dialel. Faktor kedua adalah waktu persilangan, yaitu pada pukul 04.00, 05.00, 06.00, 07.00, 08.00. Hasil analisis menunjukkan bahwa kombinasi tetua memiliki interaksi dengan waktu persilangan dalam meningkatkan keberhasilan persilangan. Tiap kombinasi tetua memiliki waktu yang spesifik untuk persilangan. Jika tetua betina Sweet Italian, waktu persilangannya semakin pagi (suhu rendah) semakin optimal, yakni di antara pukul 04.00-07.00. Untuk persilangan Katokkon×Garda maupun resiproknya, persentase keberhasilan persilangan semakin meningkat jika dilakukan pada pukul 06.00-08.00. Tidak ada penyerbukan silang antara Garda×Sweet Italian yang berhasil persilangan atau seluruhnya letal. Kata kunci: cabai, dialel , genotipe introduksi, waktu persilangan

Abstract

Plants have an important role in the development of human civilization. Human civilization progresses along with the development of the agricultural system and vice versa. Therefore humans have been trying to improve cultivated plants for thousands of years by trial and error. Traditionally, mankind have improved plants through repeated selection. However, the human population is increasing so rapidly that it necessitates a doubling of the increase in world food production. The program is constrained by the fact that we cannot increase arable land. So one solution is through biotechnology which is expected to produce more food without demanding an increase in agricultural land. At present, the application of biotechnology in agriculture can be done by genetic engineering such as genetic transformation and gene editing which are almost entirely aimed at forming transgenic plants. One of the developments in biotechnology that has been widely used is GMO (Genetically Modified Organism) or plants that have been genetically modified or are popularly known as transgenic plants. Genetic modification of plants has become the most promising approach for increasing crop yields, providing nutrients, exploiting stressed land, overcoming the energy crisis, and for producing cost-effective biopharmaceuticals.

Abstract

The aimed this study was to determine the effect of rabbit urine liquid organic fertilizer on N uptake, growth, and yield of pakcoy plants and to determine the dose of rabbit urine liquid organic fertilizer on pakcoy plants. This research used a randomized block design which repeated four times. Treatment factor: administration of rabbit urine concentration consisting of 6 treatments: U0 = 0 ml/Plant (Control or no treatment), U1 = 25 ml/Plant, U2 = 30 ml/Plant, U3 = 35 ml/Plant, U4 = 40 ml/ Plant, U5 = 45 ml/ Plant. Two phases of observation parameters were observed in this study, namely the vegetative phase which includes the height of the pakcoy plants in cm units, the number of pakcoy leaves (strands), and the area of the leaves using the length x width times the constant method. The generative phase was observed fresh weight of the plants and the total N uptake at harvest. There are significant differences in the parameters of plant height, number of leaves, and leaf area. Meanwhile, there was no significant difference in the fresh weight of the plants. There were differences in the percentage of nitrogen uptake in each treatment, the highest uptake was in treatment U5, namely using rabbit urine 45 ml/plant, and the lowest in treatment U4, namely using rabbit urine 40 ml/plant.

Abstract

The study understood the influence of giving rabbit manure ordure to nitrogen uptake, growth, and yield of pakcoy and how to judge the effect of different doses of rabbit manure on nitrogen uptake, growth, and yield of pakcoy plants. The survey was conducted in October-November 2021. The method used was a non-factorial Block Design of Randomized. The factor consisted of 6 dose levels which were repeated four times. The element was the provision of rabbit manure to pakcoy plants, composed of 6 groups of rabbit manure fertilizer doses. K0 = 0 Kg/ha, K1 = 2500 kg per hectare K2 = 5000 Kg per hectare, K3 = 7500 Kg per hectare, K4 = 10000 Kg per hectare and K5 = 12500 Kg per hectare. The results showed that all observed variables were affected: plant height, leaf number, and leaf area at the age of 27 days after planting. Each K3 variable has better growth and yields, like fresh plant weight and total N uptake. K3 treatment had the best results but was not significantly different from K2, K4, and K5.
