Abstract

The research was conducted in the village of Banyu Urip at Banyuasin district from March to June 2013. This study aimed to examine the effect of organic manure of fermented cow urine (liquid organic fertilizer/ POC) and combined with different doses of inorganic fertilizer on the growth and yield of corn land in the tidal area overflow type C. This study uses a randomized block design consisting of 5 treatment was repeated 5 times. Each treatment unit with a plot size of 1.5 m x 10 m. Treatment in this study are as follows: J0 = 100% recommended dose of inorganic fertilizer without POC cow urine; J1 = 75% recommended dose of inorganic fertilizer + POC cow urine; J2 = 50% recommended dose of inorganic fertilizer + POC cow urine; J3 = 25% recommended dose of inorganic fertilizer + POC cow urine, and J4 = 100 % POC cow urine without inorganic fertilizers. The results of fertilizer application treatments using organic and inorganic fertilizers on maize showed significant effect on all observed variables. Further test results show that the inorganic fertilizer treatment J2 = 50% of the recommended dose of cow urine + POC gives the highest yield for plant height (162.22 cm), number of leaves, corn with cornhusk weight (187.70 g), the weight of the corn without cornhusk (177.54 g), dry shelled weight (139.05 g), weight of 100 grains (30.87 g) and the number of seed rows per ear (16.60), as well as significantly different to the other treatments.

Abstract

The experiment about Diversity of weeds on rice and maize cultivation in the tidal-land Banyu Urip village subdistrict Tanjung Lago was conducted from November 2013 until Desember 2013. The purpose of the experiment is determinate the dominant weed species in cultivation of rice and maize in the tidal-land, to evaluate the results of weed control, and can be a basic weed control recommendations. The method used is squared method. The results showed that the dominant weeds in rice crops with highests sum dominance ratio (SDR) is: Ludwigia octovalvis, Fymbristilis littoralis, Alternanthera philoxeroides and Cyperus kylingia. Dominant species in maize planting is: Alternanthera phyloxeroides, Paspalum conjugatum, Borreria alata, and Euphorbia hirta. The use of a single active ingredient ?isopropylamine ? glifosat? in weed control in the tidal-land have not been able to effectively control weeds both broadleaf weeds, puzzles or grass. Mechanical methods of weed control on weeds with stoloniferous will increasingly dominant weed.

Abstract

An experiment on herbicide Penoksulam 25.5 g/L was conducted in tidal land. The objectives of this experiment was to determine the effectiveness of herbicides in controlling weeds in lowland rice. The experiment was conducted from November 2012 to March 2013. Randomized block design (RBD) with 6 treatments and 4 replications was used. The treatments tested the herbicide Penoksulam 25.5 g/L dose of 0.60 L/ha, 0.75 L/ha, 0.94 L/ha, 1,125 L/ha, manual weeding and control. The experimental unit was a plots measuring 5 m x 5 m. The results showed that the application of penoksulam 25.5 g/L  could to control weeds of lowland rice. Dominance weeds species in tidal land were Fimbristylis littoralis, Ludwigia octovalvis and Cyperus Iria. Application of herbicide at doses 0.60 L/ha up to 1.125 L/ha caused only mild symptoms of phytotoxicity on rice. Herbicides could be used to increase low land rice production on effective dose 0.60 L/ha to 0.75 L/ha.
