Abstract

The influence of global climate to the Indonesian climate condition has been in serious condition which was already in high intensity. Flood becomes the fenomena in almost all area in Indonesia. In a swamp area, it can obstruct rice plant cultivation. The submerged rice plant create the obstruction of the rice plant photosynthesis and stress after being submerged. So that  an effort is needed to increase  its tolerance and recovery in order the reduction of the unhulled crop can be reduced.   This study was aimed to obtain a method to increase rice stage is vegetative  tolerance and recovery to submergence stress through the arrangement of nitrogen fertilizer aplication and rice variety.  The experimental design used was factorial completely randomized design with six replications. The factor consists of rice varieties (Inpara 3, Inpara 5, IR 64) and  treatment (P): P1: no submergence, all N dosage prior planting; P2: submerged (7-14 DAP), all N dosage prior planting; P3: submerged (7-14 DAP), all N dosage prior planting + (Si+Zn); P4: submerged (7-14 DAP), ½ N dosage prior planting + ½ N dosage 42 DAP + (Si+Zn); P5: submerged (7-14 DAP and 28-35 DAP), all N dosage prior planting; P6: submerged (7-14 DAP and 28-35 DAP), all N dosage prior planting + (Si+Zn); P7:  submerged (7-14 DAP and 28-35 DAP), ½ N dosage prior planting + ½ N dosage 42 DAP + (Si+Zn). The results showed that the arrangement of nitrogen fertilizer application before submerged to rice plant can increase the rice plant tolerance and recovery to the submerged stress.  The increasing of tolerance and recovery can be obtained at the rice variety given ½ N dosage prior planting + ½ N dosage 42 DAP + (Si+Zn).

Abstract

Gribaldi et al, 2016. Tolerance Improvement of Two Rice Varieties to Submerged Stress Through Fertilization Treatment in Swamp. JLSO 5(1):1-9.Rice plants tolerance to the submerged conditions need to be improved in order to minimize the crop damage during the immersion. To increase the tolerance of rice plants effort is required to produce a good plant growth and early high vigor before the immersion, one through fertilization treatment. This study aims to obtain proper fertilization technology that can increase stress tolerance of rice plants submerged in swampy embankment conditions. The experimental design used in this study is the split plot design with three replications. The main plot is the fertilization treatment (P) consists of;  P0 = full doses of N fertilization without submerged, P1 =  full doses of N fertilization with submerged, P2 = ½ doses of N fertilizer with submerged.  The subplots are varieties of rice (V) consist of; V1 = Variety of Inpara 5, V2 = Variety of IR 64. The results of the study showed that fertilization treatment affect on rice plants tolerance to stress submerged, ½ doses of N fertilizing may increase the tolerance of crops to submersion stress, Variety of Inpara 5 tends to be more tolerant to submersion stress than the varieties of IR 64 at various fertilization treatment.

Abstract

Gribaldi et al, 2016.  Increasing of Growth and Sweet Corn Production Through Implementationof Tillage System and Mulching on The Dry Land. JLSO 5(2):119-126. Tillage and mulching are intended to create good soil conditions which is suitable for plant growth so could increase crop production. This study aims to gain tillage system and the organic mulching which  can improve the growth and the production of sweet corn on the dry land.  The experimental design used in this study is a randomized block design arranged as factorial with two treatments factors and three replications. The first factor is tillage (P), which consists of no tillage (P0), minimum tillage (P1), and maximum tillage (P2). The second factor is mulching (M), which consists of no mulching (M0), mulching (M1). The results showed that  tillage systems affect the growth and production of sweet corn,  mulching no effect on the growth and production of sweet corn, and mulching on minimum tillage tend to affect both the growth and the production of sweet corn on dry land.

Abstract

Gribaldi et al, 2018. Increasing the Growth and Production of Oyong Through Setting the Planting Distance and Weeding Period in Dry Land. JLSO 7(2):157-163. Luffa acutangula (angled loofah) provide great benefits so that it is popular and consumed by the public. The increasing of L. acutangula production continues to be carried out in line with increasing market demand, one of them is through the improvement of cultivation techniques, such as fertilizer application, spacing and time for weeding. This study aimed to determine the increase in growth and production of L. acutangula plants at various planting distances and weeding time. This study used a randomized block design which was arranged through factorial with three replications. The factors studied consisted of: plant spacing (J), spacing of 40 cm x 50 cm (J1), spacing of 60 cm x 50 cm (J2), and spacing of 80 cm x 50 cm (J3). Weed weeding treatment (P) consists of: No weeding (P0), weeding at 15 DAS (days after sowing) (P1), weeding at 25 DAS (P2), weeding at 35 DAS (P3), and weed-free (P4). The results showed that the treatment of plant spacing and weeding time affected the plant growth and production. Spacing at 40 cm x 50 cm resulted in the best of plant growth and yield, and weeding at 35 DAS and weed-free plant produced the best growth and yield.
