Jurnal Penelitian Pertanian Terapan is a peer-reviewed journal that publishes scientific articles from agricultural disciplines covering Plantation crops, Food crops and horticulture, food Technology, Agriculture biology and agribusiness. Articles published in the Journal of Applied Agriculture may be research results (original) and scientific review articles (review). Applied Journal of Agriculture is published by Research Unit and Community Service of Lampung State Polytechnic Society 3 edition one year, that is January, May, and September. JPPT was first published in January 2000. JPPT published a print version in 2007, then started the online version or Open Journal System (OJS) in 2014. Early online versions of JPPT or OJS editing have not yet been fully implemented online management and are beginning to make improvements Web Journal view and journal cover and OJS governance management on Volume 2 No. 2 of 2017. JPPT has been indexed on Google Scholar and Garuda IPI by 2015, and by 2017 it has indexed SINTA and registered DOAJ and Crossref in the same year. We accept submissions from all over Indonesia. All submitted articles will not be published elsewhere, original and not considered for other publications.

Abstract

Moler disease caused by Fusarium oxysporum f. sp. cepae is a main disease on shallot resulting high yield loss and always found in every shallot plantation. Biological control using antagonistic microorganism is an effective method in controlling moler disease with the mode of action of induced resistance. Expression of induced resistance may be affected by several factors such as the concentration of inducer. This research studied the effect of concentration of inducer in increasing induced resistance of shallot to moler disease so that the best contration was revealed. Single factor (spore concentration) with Completely Randomized Design and three replications was used. Spore concentration of avirulent F. oxyssporum f. sp. cepae used in this research was as follows: A = control, B = spore concentration of 104/ml, C = spore concentration of 105/ml, and D = spore concentration of 106/ml. Induced resistance was raised by soaking the shallot bulbs in the spore suspension of the inducer for about 30 minutes. The bulbs were then planted in polybags containing planting media of soil : cow manure with the ration of 1:1 (v/v). The results showed that the treatments were able to increase shallot resistance to moler disease from susceptible to moderate. Regression analysis revealed that the higher the concentration the higher the suppression of moler disease intensity. Increasing suppression of moler disease intensity may increase the growth and yield of shallot.

Abstract

Issues surrounding hybrid corn seeds in Indonesia include the increasing demand for seeds from year to year and the limited selection of hybrid varieties on the market. One solution to reduce the problem of hybrid corn seed availability is to develop new strains or varieties using parent plants from local areas. Polinela corn breeders have currently developed several hybrid corn lines (F1) that need to be tested for performance. The objective of this study was to determine the performance advantages of five Polinela hybrid corn lines compared to five superior commercial hybrid corn varieties developed by several multinational companies. The study was designed using a completely randomized block design (CRBD). The treatments used were five Polinela hybrid corn lines and five commercial hybrid corn varieties. The observations included quantitative yield components and yield potential, as well as several qualitative characteristics of the lines and varieties. The results showed that there were three new hybrid lines, namely line PL 401/PL 20, line PL.401/PL.2020, and line PL 202/PL 40), which had yield potential equivalent to the hybrid varieties BISI 18, NK 22, and Pertiwi 3, with a dry grain yield potential of between 11.7 and 12.9 tons.ha-1. There are three new hybrid corn lines with grain yield potential equivalent to three commercial varieties and higher than two comparison varieties, namely Pioneer 88 and Pertiwi 6.
