Abstract

Normally papaya plant can create sap white when tapped or in hur. Sap white it very well may be created on the entirety of its parts like natural product, blossoms and leaves petiole. Papain is a proteolytic catalyst that is created by secluding papaya sap. Papain is valuable as a breakdown of protein particles, and is regularly utilized by numerous individuals in different kinds of mechanical fields. The advantage of papain are so assorted thatb it has been broadly need for improvement perposes in industry, medication and creature feed. Papain creation can be developmentt with Biotechnology tissue culture .With improving the creation of callus plantled outgrowth leaves can expanded the cantaint of papain. The exploration goals were to decide the sorts of papaya assortments whose leaf callus could create the best papain. Realizing the papain content that can be created from three assortments of papaya leaves planted on MS and VW media. The exploration strategy utilized a totally randomized plan. Factor I was papaya assortments with 3 levels (California, Bangkok, and Gantung ). The subsequent factor is the sort of culture media (MS and VW). There are 6 mixes. Every treatment mix is rehashed multiple times with 10 test tests. The outcomes appeared; (1) There was a cooperation between the treatment of the concentrate source from the leaves of 3 sorts of Papaya assortments and the utilization of MS and VW media on callus amount and callus quality boundaries. (2 The amount and nature of callus on MS media was better compared to in VW media. (3) Callus of leaves California assortment produce Papain best than Bangkok and Gantung Variety. (3) Research result show that : all callus produces papain. The callus papaya all assortment containing papain range 11,86 % - 19,50 %.. The best found in treatment papain M1V1 ( MS Media - California (19,50 %); M2V1 (VW Media – California) 18,06 % papain content

Abstract

The research was conducted in Sawerigadi Subdistrict on Sustainable Food Agricultural Land (LP2B) consisting of five profiles. The research objectives were to determine soil characteristics in physics, chemistry, biology, and to determine the level of soil fertility on it. The research method that is; 1) Land Survey, 2) Research implementation includes the both preparation stage and data collection stage (field implementation), 3) Soil analysis includes analysis of physics, chemistry and biology. Observation and carried out soil sampling were by making soil profiles at the each point. The results of the observation physical properties from the five profiles were almost the same, which had a reddish yellow to brownish yellow color with the texture of loam, clay, clay loam to silty clay. Soil structure is angular blocky and rounded blocky and has a slightly sticky to very sticky consistency. The results of laboratory analysis of the five research profiles have slightly acidic to neutral pH, very low to low C-Organic and NTotal, very low to moderate CEC, very low to very high alkali saturation, P-available is low to very high, K-available is low to moderate, and very low to high base cations (Mg, Ca, Na, K). The value from the results of laboratory analysis of the five profiles at each layer tended to decrease with soil depth. The biological characteristics of the five research profiles are related to macro and micro activity of soil fauna, a little to a lot, the existence of macro and micro activity of soil fauna depending on vegetation conditions on the soil surface. The soil fertility level of the five research profile is in the low to medium category

Abstract

The purpose of this study was to determine the effect of biofertilizer application based on the types and spraying frequencies on the yield components of maize variety SINHAS 1. The research was conducted in Tarowang Village, Galesong Selatan District, Takalar Regency from August to November 2020. Three types of biofertilizer were used applied in five different frequencies of spraying. The study employed a split plot design with types of biofertilizer as the main plot and application frequencies as the sub plots. The research was repeated 3 times, resulted in a total of 45 experimental units. The maize variety used was SINHAS 1 and observations were made on the yield components of the ear height, wet weight of peeled cobs, ear length and diameter, percentage of seed yield, weight of 1000 seeds at 15% moisture content, and productivity. The results shows that the frequency of biofertilizer application had more dominant effect than the type of biofertilizer. The type of biofertilizer used has relatively the same role in the growth of the yield components of SINHAS 1 corn. Based on the results, it is recommended to apply the biofertilizer in four times in fertilizing the SINHAS 1 maize crop

Abstract

Shallot production and productivity of Indonesia is still low; thus, needs to be increased by providing biological organic fertilizers (POH) and growth regulators (ZPT). The research was carried out in the Covid-19 Pandemic Area from December 2019 to March 2020 in Talotenreng Village, Wajo Regency. The aim of this study was to determine the shallot (Allium ascalonicum L.) productivity by using POH and ZPT. Two experimental factors with the Randomized Block Design were used as method for this study. The first factor was the POH (P) concentration of 0 ml liter of water-1, 10 ml liter of water-1, 20 ml liter of water-1, and 30 liter of water-1. The second factor was the ZPT concentration (Z) of 0 ml liter of water-1, 1.0 ml liter of water-1, 1.5 ml liter of water-1, and 2.0 ml liter of water-1. The experimental results showed that the POH concentration significantly affected the weight of fresh blubs per plot and the concentration of growth regulators had a significant effect on the number of bulbs per plot and the productivity of shallots as much as 8.09 t ha-1.

Abstract

Bananas are a horticultural commodity that originates from Southeast Asia and the West Pacific, including Indonesia. Banana cultivation is carried out with the aim of increasing the economic value of the community by cultivating the Cavendish banana species. Cavendish banana (Musa acuminata L.) is one type of banana that is widely exported, and has high economic value. The constraints in the cultivation of this Cavendis banana plant are the small, high-quality tillers produced in large quantities and in a short time. Propagation of seeds with tissue culture technology is one solution in dealing with the problem of providing these seeds. This study aims to determine the effect of ZPT IAA and BAP concentrations on the growth of cavendish banana shoots in vitro. This research was conducted at the Tissue Culture Laboratory of the Faculty of Agriculture, Cokroaminoto University, Palopo, on Jalan Lamaranginang, Batu Pasi Village, Wara Utara District, Palopo City. Starting from January to May 2020. This research was arranged in a completely randomized design (CRD), which consisted of 5 treatments and 3 replications with a total of 15 experimental units. By giving treatment concentrations of P0: Control, P1 (IAA 0.5 mg L-1 and BAP 1 mg L-1), P2 (IAA 1 mg L-1 and BAP 2 mg L-1), P3 (IAA 1.5 mg L-1 and BAP 3 mg L-1), P4 (IAA 2 mg L-1 and BAP 4 mg L-1). With research parameters callus color, callus texture, root emergence time, shoot emergence time, number of shoots, and number of leaves. The results showed that at the concentration with treatment P3: IAA 1.5 mg L-1 and BAP 3 mg L-1 produced the highest number of leaves, namely 3 strands. The fastest root emergence time was 25.33 days and the highest number of shoots was 2.33. While for the time of emergence of treatment shoots P0: Control showed the best results, namely 7 DAS (days after planting). This is because a balanced amount of auxins and cytokinins can affect the growth of banana plants in vitro

Abstract

This study aimed to determine the effect of composition of growing media and types of fertilization on the growth and production of mustard plants. This study was carried out at the Experimental Garden of Uniprima-Sengkang from February to April 2020, using a randomized block design with two treatment factors, namely the growing media consisting of soil (control), manure + soil (1: 1), bokashi + soil ( 1: 1), and soil + manure + Bokashi (1:1:1) and fertilization, namely: without urea and Azotobacter, urea 50 kg ha1 (0.2 g/plant), Azotobacter, urea 50 kg ha-1 (0.1 g/plant+ Azotobacter). The results showed that the composition of the growing medium Soil + Manure + Bokashi (1:1:1) and fertilization with ½ Urea 50 kg ha-1 (0.1 g/plant) + Azotobacter tended to show higher result in the parameters of plant height, number of leaves, leaf width and plant weight than other treatments, however, it statistically showed no interaction between the composition of the growing media and fertilization
