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

Efforts to improve soybean productivity in tidal land, including through land improvement (amelioration) as of lime, use of improved varieties and the fulfillment of plant nutrients. This study aims to determine the adaptation of some soybean varieties for high yield in the tidal land. Research activities conducted in tidal land Banyu Urip Village Subdistrict Tanjung Lago Banyuasin District from July to September 2013 design used is Split Split Plot Design consisting of 3 factors with 3 replications. Main plots were dose Dolomite (D0= 0 ton/ha dolomite, D1= 2 ton/ha dolomite), subplots were dose of urea (P1= 25 kg/ha urea, P2= 50 kg/ha urea, P2= 75 kg/ha urea) and the plot is children soybean varieties (V1= Argomulyo, V2= Anjasmoro, V3= Tanggamus). Variables measured were plant height 17 DAT, plant height 7 MST, leaf chlorophyll and number of branches. The results showed that the varieties that produce Argomulyo plant height, leaf chlorophyll content, and the number of branches is better than the soybean crop varieties Tanggamus and Anjosmoro. Thus soybean varieties are more adaptive Argomulyo planted in tidal land.

Abstract

The objective of this research was to study the effect of nutrient fertilization on the growth and development of nepenthes (Nepenthes mirabilis). The research was conducted from October 2011 until March 2012 at Sukarami village, Palembang, Indonesia. Factorial randomized block design with two treatment factors was applied. The first factor was NPK fertilizer dosage which consisted of three levels: Po = no fertilizer, P1 = 5 g, P2 = 10 g. The second factor was number of ants: S0 = none, S1 = 20, S2 = 40, S3 = 60. The results indicated that NPK fertilizer application of 5-10 g to the planting media could increase plant growth and development, particularly in plant height, stem girth, and leaf number of N. mirabilis. Giving 60 ants per plants into nepenthes pitcher could yield the largest pitcher number, 3-4 pitcher per plant. Combination of 5 g NPK and 20 ants, similarly, combination of 10 g NPK and 0 ants resulted in the largest leaf increment (10-11 leaves). Combination of 0 NPK and 60 ants resulted in the largest pitcher number (3-4 pitcher per plant).

Abstract

Low soil fertility is the most important factor constraining corn (Zea mays L.) yield in marginal land due to soil acidity.  Corn cultivars with high nutrient efficiency and tolerance to soil acidity offer an alternative to solve the problem.  A Complex population had been formed by natural crossing among six cultivars/line expected to carry the nutrient efficiency character; Sukmaraga, Lamuru, Srikandi Kuning, Bisma, Bayu, and Toray and used as a genetic material in this study.  The objectives were (i) to evaluate the agronomic performance of complex population in marginal land under limited nutrient supply, (ii) to select the superior entries in each population for nutrient efficiency, and (iii) to identify the characters relate to yield (nutrient efficiency).  The selection of nutrient efficiency was based on the ear dry weight produced per plant (yield).  The experiment was conducted in marginal land at Agro Techno Park, Indralaya, South Sumatra in January to April 2008.  Randomized Complete Block Design with four replications was used.  The treatment was number of entries that grouped into six populations based on a female parent.  Plants were fertilized with Urea, SP-36, and KCl at 30% of standard rate.  Sukmaraga population had the best agronomic performance among six populations evaluated. The superior entries selected were top 10% of the total entries in each population with ear weight more than 150 g. All the characters (ear length and diameter, plant height, leaf chlorophyll, leaf numbers above the ear, and ear leaf area) related to yield (nutrient efficiency) but plant height is the only character measured before anthesis.  The results suggest that Sukmaraga population had use nutrient more efficiently than the other populations and plant height may be used as selection criterion in early screening large numbers of corn entries or lines for nutrient efficiency.        Key words:  Agronomic characters, corn, marginal land, nutrient efficiency
