Abstract

The objective of the experiment were to know the performance and productivity of Inpari Sidenuk Variety. The experiment was conducted in Rempanga Village, Loa Kulu District, Kutai Kartanegara Regency. The seedlings at 21 days old were planted by jajar legowo method (2:1) with plant spacing  40 cm x 20 cm x 10 cm. The numbers of seedling per hill was one plant.   All paddy plants were fertilized by 400 kg Pelangi Prima compound (20-10-10) per ha at 1 week after planting.  Nitrogen fertilizer was given 40 days after planting, where previously examined leaf colour with leaf colour chart. The treatment of  nitrogen fertilizer consists of two level i.e without fertilizer (N0) and 125 kg ha-1 (N1). Observed variabel include plant height 28 DAP and harvest time, total number of tiller at 28 DAP and harvest time, number of productive tillers, panicle length,  number of grains per panicle, percentage of filled grain, 1.000 grain weight, and yields.T test was used to analyze the data, except for the yield. The results show that N1 treatment have significant effect on plant height at harvest time, panicle length, 1.000 grain weight. While its effect on yield was 7.52 tonnes ha-1.

Abstract

The experiment was conducted in the village of Tanjung Limau, Muara Badak Sub District  of Kutai Regency, East Kalimantan Province.  The purpose of the study was to determine the success of mangrove planting activity in the study area in the mangrove forest, and to identify factors that affect the rehabilitation of mangrove forests in study area.  Data was collected by creating a transect along 100m of land rehabilitation at three different locations based on the characteristics puddle.  Observations was carried out to observe and measure the height and diameter of the plant.  Data were recorded and measured at each transect include plant data (type of plant, number of living plants, plant height and growing conditions of the plants healthy).  Based on the observation and calculation of the percentage of growing plants was conducted on 20 plots, from mangrove rehabilitation activities carried out in 2009, in 2010 gained a growing percentage of the average of mangrove plants is ±78.18%.  While the results of crop assessment carried out in 2011 acquired the mangrove plants growing percentage average is ±66.40%.  From the comparison of measurements in 2011 with the results of measurements made in this study, there was a decrease in the percentage of mangrove plants grow on average is equal to ± 11.78%.  Based on the observations and calculations of the percentages obtained transect mangrove plants growing on average at 46%.  Based on these results it can be concluded that the success rate of rehabilitation of mangrove forests growing percentage decline in the number of mangrove plants.  From the results of measurements obtained in the field of plant height and diameter high average in each lane is as follows pathway 1 is the average height of 2.28 m and a diameter of 4.48cm, 2.61m and the second path average diameter average 4.03cm and the third lane average height of 1.91meters with an average diameter of 5.62cm.  High variation of different mangrove plants.

Abstract

Objectives of the research were to study the effect of type and concentration  foliar fertilizer, as well as their interaction on the growth and yield of Eggplant; and to find proper type and consentration of foliar fertilizer for better growth and production of Eggplant.  The research was carried out from July to October 2012, since preparation of growing media until crop harvested.  It was held at Experiment at Simpang Pait Village, Long Ikis Subdistrict, Paser District, Provinsi of East Kalimantan.   The research employed Completely Randomised Design (CRD) with factorial 2 x 5 experiment and 4 replications.  The first factor was type of foliar fertilizer (J), that consisted of two levels, namely:  Green Tonik (j1), and Supranik (j2). The second factor was concentration of foliar fertilizer (K), that consisted of five levels, namely: no foliar fertilizer as control (k0); 1,0 ml l-1 water (k1); 2,0 ml l-1 water (k2); 3,0 ml l-1 water (k3), and 4,0 ml l-1 water (k4).  Results of the experiment indicated that : (1) foliar fertilizer types (J) affect very significantly on plant height at 28, 42, and 56 days after planting, but it did not affect significantly on plant height 14 days after planting, blooming time, harvest time, number of fruit, and weight of fruit; (2) concentration of foliar fertilizer (K) affect significantly on plant height at 14, 21, 28 and 42  days after planting, and weight of fruit, but it did not significantly on blooming time, harvest time, and number of fruit.  The highest weight of fruit was attained on the 4,0 ml l-1 water treatment (k4) with 0,58 kg plant-1 while the worst one was on the no foliar fertilizer treatment (k0) with 0,49 kg plant-1; and (3) the interaction between those two factors did not affect significantly on all parameters observed, but it did affect significantly on plant height 24 days after planting.
