UJI TOLERANSI PENUNDAAN WAKTU PINDAH TANAM DAN CEKAMAN KEKERINGAN TERHADAP PERTUMBUHAN DAN HASIL TANAMAN KUBIS DATARAN RENDAH (Brassica oleracea L. var capitata)
The aims of this study were determine limits tolerance of delaying transplantation and drought stress effect on growth and yield of lowland cabbage. This research was conducted from April to July 2020 at Jakabaring (104º46’44” E; 3º01’35” S), Palembang. The researchs were arranged according to the factorial randomized block design with 2 factors and collected data were analyzed using the ANOVA and t-test procedures. The first factor was Delaying Transplantation, consisted of three different times i.e. T1 = 21 Days After Sowing (DAS), T2 = 28 DAS, and T3 = 35 DAS. The second factor was drought stress phases i.e. K0 = control, K1 = head shoot growth (63 DAS – 67 DAS), and K2 = head enlargement (91 DAS – 95 DAS). The result exhibited the delay in transplantation for ≥ 28 DAS exceeded the tolerance limit which was indicated by small average number of leaves; the longer average harvest age; and inhibited growth in leaf length, leaf width, leaf area and sun canopy area; head fresh and dry weights; volume of head. The drought stress still at the tolerance limit. It can be seen from the results of the analysis of diversity, namely that drought stress has no significant effect on almost all variables except for average number of leaves by 70 DAS and 91 DAS. However, the drought stress factor in the head enlargement resulted in a decrease the level of soil moisture and leaf water content which was more than in the head shoot growth. It can be seen that the decrease in soil moisture level reaches 8% and leaf moisture content reaches 56%. Based on the results of the study, it is recommended not to carry out transplantation ≥ 28 HSS because it has exceeded the tolerance limit and can reduce the productivity of lowland cabbage head. Further research related to the ability of F1 Sehati seeds with drought stress treatment at soil moisture < 8% needs to be done to determine the specific tolerance limits and responses of plants to drought stress.
