Abstract

Production and Quality of Tomatoes (Lycopersicum esculentum Mill.) Due to Chemical, Organic, Mineral Fertilization, and The Combination of Fertilizer in Inceptisol Experimental Garden Agriculture Faculty of Udayana University The purpose of this research is to know the influence of some fertilizers to increase production and quality of tomatoes at Inceptisol, as well as chemical properties at Pegok. This research was held on August until November 2016 at the Experimental Garden, Faculty of Agriculture, and the Laboratory of Soil and Environmental Sciences Faculty of Agriculture, University of Udayana. The design used was a Randomized Block Design (RBD) with seven fertilization treatments and three replication with the number of plots 21 consist of P0 = Control, P1 = Organic fertilizers, P2 = Mineral fertilizers, P3 = Chemical fertilizers, P4 = fertilizer combination (PO + PK), P5 = fertilizer combination (PM + PK), P6 = fertilizer combination (PO + PM + PK). Statistical test by analysis of variance was significantly different when followed by LSD (Least Significance Different) test with a confidence level of 95% using Costat program.The role of chemical fertilizers are increase tomatoes production, the highest 54,67 tonnes ha-1 in treatment P3 (200 kg Phonska and 200 kg Urea) ha-1 up 207,12% compared with P0 (Control) is 17,80 tonnes ha-1, followed by P6 (5 tonnes Organic Fertilizer + 2,5 tonnes Chemical Fertilizer + 100 kg Phonska + 100 kg Urea) ha-1 is 41,20 tonnes ha-1 up 131,46% compared with P0 (Control), P5 (100 kg Phonska + 100 kg Urea + 2,5 tonnes Chemical Fertilizer) ha-1 is 40,13 tonnes ha-1 up 125,47% compared with P0 (Control), P4 (5 tonnes Organic Fertilizer + 2,5 tonnes Chemical Fertilizer) ha-1 is 28,53 tonnes ha-1 up 60,30% compared with P0 (Control), P1 (10 tonnes Organic Fertilizer) ha-1 is 27,60 tonnes ha-1 up 55,06% compared with P0 (Control), P2 (5 tonnes Chemical Fertilizer) ha-1 is 26,33 tonnes ha-1 up 47,94% compared with P0 (Control). The highest quality of tomato was shown by formula of P5 : combination of chemical and mineral fertilizer.

Abstract

The Relationship Between Population of Whiteflies (Bemisia tabaci) (Genemadius) (Hemiptera : Aleyrodidae) with Incident of Yellow Disease on Tomato Plant (Solanum lycopersicum Mill.) in Dusun Marga Tengah, Kerta Village, Payangan District, Bali The disease of tomato is namely yellow disease that is caused by a Geminivirus from species Tomato Yellow Leaf Curl Virus (TYLCV) . That virus can be propagated through the vector that is Bemisia tabaci.This study aimed to know the relationship between population of Bemisia tabaci (Genemadius) (Hemipteraaleyrodidae) with incident of yellow disease on tomato plant (Solanum Lycopersicum Mill.) This study is located at the center of tomato cultivation in Dusun Marga Tengah, Kerta Village, Payangan, Bali from December 2016 to February 2017. This study observe the number of nymphs Bemisia tabaci on tomato plants as sample that choosen and observed the incidence of disease in tomato plant area. Relationship between yellow disease incidence with population of Bemisia tabaci is analyzed by a linear regression model. The results showed that the incidence of yellow disease in tomato plants correlated positively and significant with the increase of vector insect population Bemisia tabaci that is 87,37%.
