Abstract

This research aims to determine the effect of various types of mulch on the growth and yield components of shallot varieties Lembah Palu were are given the containment. This research was conducted at the Hall Horticulture Seed Napu Watumaeta Village, Poso district, Central Sulawesi Province. The timing of the research in the May-July 2015. This study uses a randomized block design one factor. The treatments tested were four types of mulch that is without mulch, rice straw mulch, black plastic mulch and silver plastic mulch, each treatment was repeated three times so that there are 4 x 3 = 12 units of a plot. Data processed by analysis of variance and differences  among the treatments were tested were determined by LSD 5%. The results showed that rice straw mulch and silver plastic mulch resulted in the highest increase plant height and length of the longest leaf at the age of 50 days after planting. Black plastic mulch, and silver plastic mulch and without mulch produce the largest bulbs convolution results.

Abstract

The aims of this research are to determine growth and production of chili (Capsicum annuum L.) provided compost and bacteria Azotobacter sp. This study used a randomized block design factorial with two treatment factors. The first factor is compost consisting of : compost 15 t ha-1, 20 tha-1, and 25 t ha-1. The second factor is the bacteria Azotobacter sp. consisting of without giving Azotobacter sp. and giving Azotobacter sp. Each treatment was repeated four times so that there are 24 units trial. The results showed the bacteria Azotobacter sp. administration significantly affected plant height, root length, root volume, fresh weight of plants, plant dry weight, number of fruit crops, and the weight of the fruit crop. The results showed plant height, root length, root volume, fresh weight of plants, plant dry weight, number of fruit crops, and the weight of the fruit crop the highest in the delivery of Azotobacter sp. is each by 42,1 cm, 238,4 cm, 8,88 ml, 22,1 g, 5,60 g, 4,92 buah, 5,79 g. While the treatment of compost and their interaction had no significant effect on the observed variables. Key Words : Azotobacter sp., Chili, Compost, growth, production.

Abstract

The research aimed to obtain the better concentration of liquid organic fertilizer on the growth of each cacao, compare the growth of cleft grafting seedling of Sul 1 and Sul 2 cacao clones and gain the concentration of liquid organic fertilizer which was better on the growth of early grafting cacao seedling. The research was conducted in December 2015 to February 2016 in Green House of Faculty of Agriculture, Tadulako University. The research used two-factor Randomized Block Design. The first factor was clone consisting of Sul 1 and Sul 2 clones. The second factor was the concentration of liquid organic fertilizer consisting of concentration of liquid organic fertilizer by 0.0%, concentration of liquid organic fertilizer by 0.25%, concentration of liquid organic fertilizer by 0.50%, and concentration of liquid organic fertilizer by 0.75%. The data were analyzed by using analysis of variance of median value test done with BNJ 5%. The research showed that the concentration of liquid organic fertilizer by 0.75% is better on Sul 1 clone. It was shown by more numerous and long shoots, more numerous and wide leaves and the more total chlorophyll. Mean while, the concentration of liquid organic fertilizer which is better for Sul 2 clone is the 0.50%.       it was shown by more numerous and long shoots, more numerous and wide leaves and the more total chlorophyll.

Abstract

The study aimed to find plant spacing for better growth and yield of wetland rice crops under direct seeded planting system.  The study was arranged in a Randomized Block design with two factors i.e. two different spatial plantings and three kinds of Jajar Legowo patterns.  The plant spacing of 25 cm  x 25 cm with Jajar Legowo pattern of  2:1 produced highest grain yield (8.21 ton ha-1) followed by the plant spacing of 20cm x 20cm with Jajar Legowo pattern of 3:1 (7.21 ton ha-1).  Jajar Legowo pattern of 3:1 resulted in better plant height (74.80cm), similarly plant spacing of 25cm x 25 cm also had same plant height, more tiller number (30.69) and panicles per clump, longer panicle length and more grain number. Key Words: Jajar Legowo, Plant spacing, and Rice.

Abstract

This study aims to get the right pattern Legowo row on each plant spacing; get Legowo row patterns are better on growth and yield of paddy; get better spacing on growth and yield of paddy. The study design randomized complete block design (CBD) with two factors, the first factor was spacing of the second stage and the second factor was the pattern Legowo row with 3 levels thus obtained 6 treatment combinations. Each combination treatment was repeated three times as a group so that the required 18 experimental plots. The results showed that the adoption of patterns Legowo row 2: 1 at a spacing of 20 cm x 20 cm resulted in higher plants while a spacing of 25 cm x 25 cm pattern Legowo row 3: 1 resulted in higher plants. Implementation patterns Legowo row 4: 1 to produce tillers and panicles number per clump more, whereas usage patterns Legowo row 3: 1 resulted in higher grain with an average of 7.29 tonnes ha-1 compared to other plant spacing pattern.
