Plant Spacing Applications and Weeds Extracts against Plant Tomato (Lycopersicum esculentum, Mill) Productivity Intercropped with Aromatic Plants

Olivina Sofia Messakh, Zainal Arifin


Aims of this study are to find method to increase the productivity of tomato plants per unit area of land with the different of plant spacing and doze variation of weed extract that can enchance the productivity of tomato plants. The design used was randomized block 2 factorial design, the first factor was plants spacing which consist of 3 level, namely J1: 50 x 50 cm; J2: 50 x 60 cm; and J3: 50 x 70 cm;   and the second factor was doze variation of weed extract as much as 5 level namely G0: without plant extract; G1: Cyperus rotundus extract 40g/liter; G2: Cyperus rotundus extract 80 g/liter; G3: Ageratum conyzoides extract 40 g/liter; and G4: Ageratum conyzoides extract 80 g/liter. Each of treatment combination was repeated three times.The results indicate that plant spacing  is significant effect on plant height 5 WAP, number of fruits, fruit diameter, fruit weight, plant dry weight, leaf area 12 WAP and leaf area index 12 WAP. Weed extract was significant effect on number of fruits, fruit diameter, leaf area 12 WAP and leaf area index 12 WAP.

Keywords: tomato, intercropping, weed extraction, Cyperus rotundus, Ageratum conyzoides.
