Abstract

Plants which experienced the stress immersion of photosynthesis and its respiration were hampered, as a result of gas diffusion and penetration of low light. Penetration of light that can be captured by the plant which experienced the stress immersion is highly depending on the turbidity of water and the height of immersion. Some rice varieties have different growth responses to the stress immersion at various water turbidity. This study aims to obtain varieties that are tolerant to stress immersion in various conditions of water turbidity. The experimental design used in this research is completely randomized design arranged in a factorial with two factors treatments and three replications. The first factor is rice varieties consists of IR 64 (V1), Inpara 3 (V2), and Inpara 5 (V3). The second factor is the turbidity of water immersion consists of without an immersion (K0), immersion in pure water (K1), immersion in ½ water turbid (K2), immersion in water turbid (K3). Submersion did on 7hst for 7 days. The results showed that rice crops which experienced the stress immersion in various water turbidity showed a response to agronomic character’s changing which is different, Inpara 5 varieties tend to be more tolerant of stress immersion in various water turbidity, the more turbid water immersion, the greater damage to the rice crop and the lower production of grain produced per hectare

Abstract

Maize is cultivated not only as producer but also as a seed of green fodder. Increasedcorn needs according to population growth and the increasing need for animal feed, inwhich 52.4% of the feed is from cron. This study aimed to determine the effect of plantingdistance on the production of hybrid corn plants bisi-2. This study used a randomizedblock design experiment (RAK) are arranged in groups and comprise 1 to 3 treatmentfactors, namely: J1 (50 x 20 cm), J2 (50 x 40 cm), A3 (50 x 60 cm) and 5 replications.Planting the drill is done by using the spacing of the rows in each treatment, the seed isinserted into the planting hole as much as 2 seeds per hole. The results of the study givinga spacing significantly affected maize crop production parameter dry weight of plants, cobwet weight, dry weight and pith. Giving a spacing of 50 cm x 40 cm can not increase theproduction of corn. Giving a spacing of 50 cm x 60 cm gives the best effect on theproduction of corn.

Abstract

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, 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.
