Abstract

The hydroponic system is still constrained by the high cost of AB mix nutrients. This study aimed to determine the effect of adding rabbit urine as Liquid Organic Fertilizer (LOF) to the nutrient solution on the growth and yield of three varieties of pak choi (Brassica rapa L.) with a wick hydroponic system. The experiment used a split plot design for the main plot of LOF (K) which consisted of 3 levels, namely control (K0), mixture AB + 6 ml/l LOF (K1), and mixed AB + 12 ml/l LOF (K2), and sub plot of varieties (V) consisting of 3 levels, namely Nauli f1 (V1), Emone 26 (V2) and Green (V3). The results showed that increasing the concentration of LOF in rabbit urine in 12 ml/l nutrient solution did not have any significantly different result on the growth and yield of pak choi plants. However, Emone 26 varieties showed a very significant effect on growth and yield, with average values on the parameters of plant height, number of leaves, fresh weight, crown fresh weight and crown dry weight at 35 Days After Planting (DAP). 25.14 cm, 14.22 pieces, 94.69 g, 79.06 g, and 4.43 g, respectively. There was no interaction between the addition of LOF rabbit urine to the growth and yield of three varieties of pak choi on all parameters observed. Further research needs to be done on other hydroponic systems in order to obtain the right POC concentration to reduce the use of AB mix nutrients.

Abstract

The purpose of this study was to determine the effect of plant spacing and variation of weeding time on the growth and yield of curly red chili varieties of Kencana (C.annuum). This research was conducted at IP2TP Balitsa Serpong from May to September 2022. The experiment used a randomized block design (RBD) with 2 factors. The first factor was plant spacing (J) which consisted of 2 levels, namely J1 (50 cm x 50 cm), and J2 (50 cm x 60 cm). The second factor was weeding time (P) which consists of 5 levels, namely P0 - (With Weeds), P0 + (Without Weeds), P1 20 Days After Planting (DAP), P2 40 DAP, P3 60 DAP. Parameters observed included plant height (cm), number of leaves (strands), stem diameter (cm), fruit length (cm), fruit diameter (mm), number of fruit (fruit), fruit weight (g), number of fruit per plot (fruit), and fruit weight per plot (g). The J2 treatment gave the best results on the growth and yield of the Kencana variety but did not give the best results at 28 DAP, 1st harvest fruit diameter, and 3rd harvest fruit weight. The J2 treatment also gave the best results on the growth and yield of the Kencana variety but did not give the best results at 28 DAP, 1st harvest fruit diameter, and 3rd harvest fruit weight. The combination of plant spacing of 50 cm x 60 cm and weeding time of 60 DAP gave the highest average fruit length, which was classified as no 2 quality according to SNI.
