Abstract

Maintaining soil quality can be done by cultivating soybean using the conservation soil tillage principle, which can be applied in no tillage soil system. The purpose of this study was to obtain the influence of the type of leaf fertilizer and the frequency of leaf fertilizer application on the growth and yield of soybeans in the without tillage system. This research was conducted in Kedawung, Sragen Central Java on May-August 2018. The research used randomized complete block design (RCBD) with 7 levels and 4 replications. Foliar fertilizer was given every 10 and 15 days. The observed variables were periodic observations, maximum vegetative, and yield. Maximum vegetative and periodic observations showed that P3 (gandasil D fertilizer every 15 days) has significant effect and resulted the highest yield. The results of the study showed that gandasil D fertilizer every 15 days treatment increased leaf area index. Gandasil b every 15 days treatment increased the yield of 100 seeds, but reduce the quantity of seed weight/plot, and foliar fertilizer is not effectively used in this cultivation.

Abstract

Sugar palm (Arenga pinnata) flour industry in Tulung, Klaten district is the center of the sugar palm flour production industry in Central Java. In the processing of sugar palm flour is a lot of obstacles, one of which is environmental pollution resulting from waste liquid produced. This reasearch was purposed to determine the effect of liquid organic sugar palm fertilizer with a variety of decomposition starters on the growth and yield of maize. The research was held from September to December 2014 at the Greenhouse of Faculty of Agriculture, Sebelas Maret University (UNS) of Surakarta with the design used was Randomized Complete Block Design (RCBD) that there is one factor, that is a variety of decomposition starters. The treatment of each repeated four times in order to obtain 24 plots. The results showed that fertilization using sugar palm liquid waste fermented with variety of decomposition starters have no significant effect on the growth and yield of maize. The combination treatment of sugar palm liquid waste fertilizer fermented with EM-4 resulted higher yield potency grain per cob is 36,49 grain or 7,3% of normal production grain per cob.

Abstract

Soybean is one of the commodity with high market demand. Soybean production process is limited by the lack of land. One of the efforts to improve the usefullness of land and production of soybean is an intercropping method between soybean and corn. Intercropping that over using chemical fertilizers have impact negatively on the land. Therefore, utilization of organic fertilizer to reduce the chemical fertilizer is necessary to prevent the damage of the land. This study aimed to examine the utilization of organic fertilizer to replace a part of chemical fertilizer. This study was conducted at the Center for Dryland Research Faculty of Agriculture, University of Sebelas Maret Surakarta, Jumantono, Karanganyar started on February until May 2013. The experiment was conducted using Randomized Complete Block Design (RCBD) with one factor fertilization consists of 6 levels, one control and two comparators monoculture. The results showed that application of organic fertilizer 800 kg ha-1, Urea 125 kg ha-1, SP-36 83.33 kg ha-1 and KCl 83.33 kg ha-1 with the highest yield for soybean 1.52 tons ha-1 and corn 1.25 tons ha-1 is optimal balance dosage of organic and inorganic fertilizers to soybean-corn intercropping. The treatment did not significantly different with inorganic fertilizer intercropping experiment. The research treatment showed that N, P and K fertilizer can’t be reduce by organic fertilizers.

Abstract

Erosion is the main factor causing  land degradation in area of planting vegetables dominated by Andisol soil. Andisol soil contains more fraction of dust so it is easily transported by runoff. This study aim to determine the influence of mulching corn stem with a terrace strengthen (Vetiveria zizanioides, Coix  lacryma-jobi  L., Panicum muticum, Annona squamosa) to surface runoff, erosion, growth and result of plant (red lentils, cabbage and white lentils) in Andisol soil. This study uses a randomized complete block design with four (4) treatment and repeated three (3) times as a group so that there are twelve (12) experimental unit. The grouping based on kinds of plant that are cabbage, red lentils and white lentils. The results showed that MS4 treatment (mulch corn stem twelve (12) ton/ha with panicum muticum+ Annona squamosa as terrace strengthen) produces smallest of surface run off, erosion and dry weight of weeds, increased growth and canopy and increased crop yields 40.27% of red lentils, 57.10% of cabbage and 14.54% of white lentils.

Abstract

Palm sugar solid waste create problem for local resident. Palm sugar liquid waste is one of the material that could potentially be used as an organic fertilizer. This study aims to obtain an organic fertilizer that can increase growth and yield of tomatoes. This study was held in the greenhouse of Faculty of Agriculture, Sebelas Maret of University (UNS). The study used Randomized Block Design Complete (RCBD) with one factor, that is the composition of organic fertilizer consisted of control (P0), palm sugar solid waste with cattle stool (P1), palm sugar solid waste with goat stool (P2), palm sugar solid waste with chicken stool (P3), palm sugar solid waste with quail stool (P4), palm sugar solid waste with bran (P5). Each treatment was repeated 4 times. Data were analyzed using ANOVA and be continued with Least Significant Differences (LSD). The result show that application of organic fertilzer from palm sugar solid waste with bran can increase growth and yield of tomatoes.

Abstract

Arrowroot is a plant that potential to be one of the alternative food source for the community. The intensity of the light received by the plant is one of the influential factors important for plant growth. This study was conducted to determine the arrowroot plant growth analysis at different light. This research was conducted at the Experimental Farm Faculty of Agriculture, University of Sebelas Maret in Jumantono Karanganyar. This study uses a randomized block design Complete (RAKL) one treatment factor with four levels ie without shade, 31% shade, 51% shade and 73% shade. Data were analyzed by analysis of variance and if there is a significant difference continued with DMRT (Duncan Multiple Range Test) level of 5%. The results showed that the treatment of 51% shade known to give better growth results in some growth variables observed were plant height, leaf area index (LAI), segment length and chlorophyll contents.
