- Abstract
Pb input into agricultural land in addition to the natural geological activities, can also be produced from anthropogenic activities such as the application of organic matter, fertilizers and the use of pesticides. Although Pb is not an essential element for plants, plants can absorb it from the soil and accumulate it in plant parts in various concentrations. This study aims to determine the effect of the use of production inputs in the form of fertilizers and pesticides containing Pb on the growth and yield of vegetable crops. The research method used is Split Plot Design, as the main plot namely the source application of Pb (A) consists of 4 levels (A1: pesticide (99 mg Pbkg-1); A2 = fertilizer (21 mg Pb/kg); A3 = Pb(NO3)2 (50 mg kg−1) and A4= control (without Pb input) and as a subplot namely type of vegetable (B) consists of two levels chinese cabbage(B1) and bean (B2). In general, the results show that the application of Pb sources from the use of fertilizers and pesticides has no significant effect on plant height, number of leaves, fresh weight, and total dry weight of the chinese cabbage and bean. Application of different Pb sources affects on the total chlorophyll of the chinese cabbage and bean vegetable plants. Chinese cabbage plants that applied Pb source from pesticides produced higher total chlorophyll (17,21 mg g−1), on the contrary, on the bean plants total chlorophyll that applied to the Pb source from pesticides produced the lowest total chlorophyll (4,66 mg g−1). The shoots of Chinese cabbage which applied Pb from pesticides accumulate Pb equal to 0,445 mg per dry weight (concentration of 38,63 mg Pb kg−1) higher than the accumulation of Pb on the control Chinese cabbage shoot. The Pb concentration that exceeds the safe limit for food from vegetables equal to 0,5 mg kg−1, needs to be a serious concern to be minimized.
