Abstract

Plutella xylostella is a major pest on cabbage plants. At times of hight population numbers, the larvae will eat all the leaves and leave only the bones of the leaves, this will cause severe damage, thereby reducing production yields. The result are quickly seen despite the negative impact, as a result the crops that should be of hight quality and nutrition become contaminated with chemical pesticide residues and are dangerous if consumed. The results showed that the highest mortality was in the single test of neem leaf extract, which was 57% and the highest mortality was in the mindi leaf extract which was 33%. Keywords: Mortality, Plutella xylostella, Leaves of Neem, Leaves of Mindi

Abstract

Tomatoes are a horticultural commodity that is widely consumed by the public, so they need to be increased using organic fertilizer plus Trichoderma. This research aims to determine the effect of organic fertilizer plus on increasing the growth and production of tomato plants. This study used a randomized block design with treatments namely no organic fertilizer plus (A0), organic fertilizer plus 3 t.ha-1 (A1), 6 t.ha-1 (A2), 9 t.ha-1 (A3), 12 t.ha-1 (A4), and 15 t.ha-1 (A5). The variables observed were plant height, number of leaves, number of branches, number of flowers forming fruit, number of flowers, number of fruit, fruit weight, fruit diameter and productivity. The observational data is analyzed for variance and data that shows a real effect will be further tested using Duncan's Multiple Range Test. The results of the study showed that organic fertilizer plus treatment had an effect on the growth of tomato plants. The highest variables of plant height, number of leaves, stem diameter and number of branches were obtained in the organic fertilizer plus 15 t.ha-1 (P5) treatment which was not significantly different from the 12 t.ha-1 (P4), 9 t.ha-1 (P3), 6 t.ha-1 (P2), 3 t.ha-1 (P1), but significantly different from the treatment without organic fertilizer plus (P0).
