Abstract

This study aimed to determine the level of land suitability for cultivation of coffee, cocoa and cashew on the Experimental Farm of Halu Oleo University in the District of North Moramo, South Konawe. The method used in this research was the method of soil survey aimed to obtain data on soil characteristics. Land suitability evaluation was done by using the method of matching between the land characteristics and the eligibility criteria to grow crops that will be developed.  Results on actual land suitability for coffee crop was quite suitable (S2) with a land area of 149.6 ha, marginally suitable (S3) with total area of 101.06 ha and not suitable (N) with 3.01 ha land area; whereas for cocoa and cashew plants was marginally suitable (S3) with total area of 246.21 ha and not suitable (N) with 7.46 ha land area. Potentially, coffee plants were quite suitable (S2) with a land area of 213.65 ha, marginally suitable (S3) with a land area of 37.01 ha and not suitable (N) with 3.01 ha land area; cocoa plants were marginally suitable (S3) with a land area of 250.76 ha and not suitable (N) with 3.01 ha land area while cashew plants were quite suitable (S2) with a land area of 246.21 ha, marginally suitable (S3) with 4.45 ha land area and not suitable (N) with 3.01 ha land area.  Factors limiting plant growth were rainfall, air temperature, air humidity, soil depth, slope and erosion.  Management action carried out for the limiting factors erosion and slope was by land conservation, for the limiting factor of rainfall was by irrigation system settings and no management actions coul be done for the limiting factors of air temperature, humidity and soil depth because the limiting factors are permanent.

Abstract

The rain-fed rice fields of Jati Bali Village have contributed to increasing rice productivity in South Konawe Regency. This study aims to determine the status of soil fertility in rainfed paddy fields and to determine fertilization recommendations in rainfed lowland fields. This research was conducted in Jati Bali Village, West Ranomeeto District, South Konawe Regency and the Biology Laboratory of the Faculty of Mathematics and Natural Sciences, Halu Oleo University, taking place from May to July 2022. This research used a purposive sampling method based on different altitudes. Soil samples were taken, namely upper rice fields (65-71 m asl), middle rice fields (58-64 m asl) and lower rice fields (50-57 m asl) then carried out laboratory analysis on the soil samples. The results showed that the fertility status of rainfed lowland rice fields was classified as low and moderate. Low soil fertility is found in the upper paddy fields and middle paddy fields. While soil fertility is found in the lower paddy fields. Fertilizer recommendations for the upper paddy fields are 200 kg ha-1 of NPK fertilizer, 175 kg ha-1 of Urea fertilizer and 2 t ha-1 of manure. While the recommendation for fertilizer for middle and lower paddy fields is the application of NPK fertilizer as much as 150 kg ha-1, Urea fertilizer as much as 200 kg ha-1 and manure as much as 2 t ha-1.

Abstract

This study aims to determine the effect of the use of Inceptisol soil on the coast of Napabalano Subdistrict and the application of cow dung compost as a planting medium on the growth of Pulut maize (Zea mays var. ceratina) and determine the best dose of cow dung compost on the utilization of Inceptisol soil on the coast of Napabalano District against maize growth. This research took place in October-January 2022. This study used a Randomized Block Design (RBD) with five treatments, namely without cow dung compost (P0); cow dung compost 100 g polybag-1 (P1); cow dung compost 200 g polybag-1 (P2); cow dung compost 300 g polybag-1 (P3); cow dung compost 400 g polybag-1 (P4), repeated four times to produce 20 experimental units. The variables observed were nutrient levels of N, P, and K in Inceptisol soil on Napabalano District's coast and plant growth, including plant height and number of plant leaves. The results showed that cow dung compost increased the N-total nutrient content from 0,072% to 0,11%, P-total from 20,34 mg 100g-1 to 29.29 mg 100g-1, and K-total 21,24 mg100g-1 to 30,60 mg100g-1. Giving cow dung compost, 400 g polybag-1 significantly increased plant height and the number of plant leaves compared to other treatments.

Abstract

Nickel mining activities in Southeast Sulawesi have triggered the physical, chemical and biological degradation of soil. Therefore, the application of organic amendment was an alternative solution to restore the degraded soil. This research aimed to study the effect of ameliorant on soil chemical properties and the effect of ameliorant on yield of cayenne pepper on ex-nickel mining soil. This research was conducted on Field Experimentation Station. Faculty of Agriculture Halu Oleo University, from January to April 2021. This study was carried out using a Randomized Block Design (RBD), which consists of 4 treatments namely without ameliorant (B0), cow manure 60  (B1), biochar husk 60  (B2), cow manure + biochar husk (1:1) 60  (B3) with 4 replications. The results showed that overall ameliorant had an effect on increasing soil pH, Organic-C, available-P, available-K, and Cation Exchange Capacity. Soil pH increased from 4.32 to 6.1, C-organic increased from 0.78% to 1.89%, available-P increased from 3.87ppm to 16.87ppm, available-K increased from 10 mg 100g-1 to 40 mg 100g-1, Cation Exchange Capacity increased from 0.1 me 100g-1 to 75.11 me 100g-1, while total-N increased from 0.21% to 0,38%. Application of 60  (B1) of cow manure increased the plant height and the number of leaves by 29.65 cm and 51,25 respectively.

Abstract

Ultisol still has the potential for the development of dry land agriculture. However, the utilization of Ultisol faces soil fertility constraints which can inhibit plant growth, especially bean plants, if not managed properly. The aim of the study was to determine the effect of manure and dosage on pH, organic C, total N, and yield of chickpea plants (Phaseolus vulgaris L.). The research was conducted at Field Laboratory II, Faculty of Agriculture, Halu Oleo University, from November 2021 to January 2022. The research was arranged according to a Split Plot Design with a factorial pattern. The main plot consists of three levels, namely chicken manure (KA), goat manure (KK) and cow manure (KS). Subplots consisted of 4 levels, namely: without manure (D0), 2% manure (D1), 4% manure (D2) and 6% manure (D3). The results showed that chicken manure, goat manure and cow manure had an effect on soil pH, C-organic and N-total. The highest increase in soil pH was achieved in chicken manure treatment (6.3), followed by goat manure and the lowest in cow manure. The highest increase in C-organic occurred in the chicken manure treatment (2.07%), then goat manure and the lowest was cow manure. The highest increase in N-total occurred in the cow manure treatment (0.13%), then the chicken manure and the lowest was in the goat manure treatment. There was no significant interaction between manure and dosage on bean yields. Manure has an independent effect on the number of pods and pod weight. The highest number of pods and the heaviest weight were achieved in the KK treatment with 20.17 pods and 97.17 g weight, followed by the KA treatment with 17.00 pods and 75.75 g weight and in the KS treatment with 3.25 pods and weighs 12.17 g.

Abstract

This study aimed to determine the changes in some chemical properties of coastal soil and the growth of pakcoy (Brassica rapa L.) given chicken manure and to obtain a treatment that changed the chemical properties of coastal soil and the growth of pakcoy (Brassica rapa L.) was more good. This study used a randomized block design (RBD) consisting of 4 treatments, namely A0 (without chicken manure), A1 (100 g chicken manure polybag-1), A2 (200 g chicken manure polybag-1), and A3 (300 g chicken manure polybag-1). Soil analysis was carried out at the Nanotechnology Laboratory, Halu Oleo University. This study showed that chicken manure increased the nutrient content of total N-, P-available, C-organic, and pH in coastal soil, with a dose of organic fertilizer that gave the best effect, namely 100 g polybag-1.
