PENGARUH DOSIS NUTRISI ORGANIK CAIR PLUS INSEKTISIDA NABATI TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN LOBAK PUTIH (Raphanus sativus L.)

Abstrak

The aim of the study was to determine the effect of liquid organic nutrition on the growth and production of white radish plants. The research was carried out at Experimental Garden I and Agronomy Laboratory, Faculty of Agriculture, Halu Oleo University, Kendari, from March to May 2022. The study used a randomized block design consisting of five treatments, namely without giving liquid organic nutrients plus vegetable insecticides or control (P0), liquid organic 30 ml + vegetable insecticide 20 ml/liter of water (P1), liquid organic nutrition 60 ml + vegetable insecticide 30 ml/liter of water (P2), liquid organic nutrition 90 ml + vegetable insecticide 40 ml/liter of water (P3), liquid organic nutrition 120 ml + vegetable insecticide 50 ml/liter of water (P4). Each treatment was repeated three times so that there were 15 experimental units. The variables observed were plant height, number of leaves, tuber length, tuber diameter and tuber fresh weight. Observational data were analyzed by means of variance. If the variance shows a significant effect, then it is continued with the Least Significant Difference Test (BNT). The results showed that the administration of several doses significantly affected the growth and yield of white radish. The best treatment was obtained at a dose of liquid organic nutrients plus vegetable insecticides 60 ml + 30 ml/liter of water with a plant height of 26.01 cm, number of leaves 16.66 cm, tuber length 26.67 cm, tuber diameter 6.42 cm and fresh weight. tubers 505.05 g.
