Abstract

Susilawati et al., 2012. Agronomic Characteristics and Tolerance of Red Chili Varieties under Water Logging Stress during Generative Phases. JLSO 1(1):22-30.The research objective was  to evaluate the responses of growth and tolerance of red chilli under waterlogging stress during generative phases. Experiments were conducted in village   Alang-alang Lebar Palembang, South Sumatra, from April  to November 2010. Experimental design used was split plot with three replications. The main plot was waterlogging for 1, 2, 3 and 4 days. The subplot was  red chili varieties consisted of Kiyo F1, Bravo F1, Taro F1, Lembang 1, Laris, Riawan, Mario and Kusuma. The results showed that the maximum period of waterlogging  of Red chilli plants in the generative phase was three days. Increased duration of waterloggingduring the generative phase significantly decreased the ability of plants to survive, the number of live plants,  plant height and the number of branches. Based on the agronomic characteristics found in the study, the variety that is the most  tolerant to  waterlogging  during the generative phase was Kiyo F1.

Abstract

Plants get stressed shortly after submerged, to improve the recovery and subsequent metabolic processes as well as internal repairs required plant availability of adequate carbohydrate reserves after submerged. Giving fertilization treatment after being submerged is an effort to improve plant recovery after being submerged. This study was aimed to obtain the best fertilization to increase rice recovery to submergence stress through the fertilization after being submerged. The experimental design used was factorial completely randomized design with three replications. The factor consists of rice varieties (Inpara 3 dan IR 64) and treatment (N): Without soaking, basic fertilization (N1), submerged 7-14 DAP (fertilization of N, P2O5, K2O (N2), and fertilization of N, P2O5, K2O + (Si + Zn) (N3), as well as fertilization of N, P2O5, K2O + PPC micro (N4)) given 7 days after submerged, the submerged 7-14 and 28-35 DAP (N, P2O5, K2O (N5), and fertilization of N, P2O5, K2O + (Si + Zn) (N6) and fertilization of N, P2O5, K2O + PPC micro (N7)) given 7 days after the first submerged. The results showed that the growth and grain yield decreased with more frequent of rice plants in stress submerged condition. Fertilization can improve recovery after being submerged rice plants, where the best recovery obtained on varieties of rice plants treated with fertilization of N, P2O5 and K2O + PPC micro 7 days after being submerged.

Abstract

The research has been conducted at rainfield lowland of non tidal swamp in Kecamatan Rambutan Kabupaten Banyuasin in March to May 2014. Objection of research was to find the treatment for seed of rice before planting with application of Zn and nitrogen fertilizer. This factorial experiment was set by randomized block design with three replications. First factor was 6 rice varieties, second factor is two levels of Zn treatment (0 mM and 5,0 mM), and third factor is two level of N fertilizer (30 and 60 kg/ha). The 15-day seedlings, were submerged for 5 days. The parameters, dry weight of seedling, carbohydrate of stem, and chlorophyll of leaf, were measured on 10 days after submergence treatment. Carbohydrate and chlorophyll was measured according to the methode of Yoshida et al. (1976). Result of research showed that application of Zn and N increased dry weight, carbohydrate, and chlorophyll of seedling. Therefore rice seedling will be more tolerant in submergence stress.
