Abstract

Cocoa pod husk is potential organic matter source to improve soil fertility as it contains relative high nitrogen and potassium. The objective of this study was to explore the effect of urea and cocoa pod husk compost application on availability of N, P, and K, uptake of N, P and N, and yield of mustard in an Inceptisol.  Treatments tested were K0 = control, K1 = 100% Urea, K2 = 75% Urea and 25% cocoa pod husk compost, K3 = 50 % Urea and 50% cocoa pod husk compost, K4 = 100% cocoa pod husk compost, and K5 = 200% cocoa pod husk compost. Results of this study showed that application of 75 %  Urea (163.05 kg ha-1) and 25% cocoa pod husk compost (2.717 Mg ha-1 ) increased available N of 230.43%,  available P of 26.10 mg kg-1, and available K of 0.95 cmol kg-1 in the soil studied. Application of 200% cocoa pod husk compost (21.739 t ha-1) resulted in the highest organic C (2.17%) and pH (5.58). The highest N uptake by mustard plant (16.44 mg plant-1) was obtained from 100% Urea (217.40 kg ha-1 ) treatment. Application of 75% Urea and 25%  cocoa pod husk compost produced the highest P uptake (3.08 mg plant-1), K uptake (6.39 mg plant-1), leaf area (635.46 cm2 plant-1), fresh weight (48.57 g plant-1 ) and dry weight (2.35 g plant-1), which were not significantly different with the application of  100% Urea.

Abstract

Ultisols are characterized by less aggregate stability, high clay, solid, organic material, and low pH. These can be managed by using calcification, augmentation of organic material and fertilization. One of soil amendments than can be used to improve properties of Ultisol is biochar.  The objective of this study was to elucidate the effects of cocoa's shell biochar application on soil aggregate stability and growth and yield of maize at an Ultisol. Treatments tested in this study were D0 (no biochar application), D5 (application of 5 t biochar ha-1), D10 (application of 10 t biochar ha-1), D15 (application of 15 t biochar ha-1), D25 (application of 25 t t biochar ha-1), dan D40 (application of 40 t biochar ha-1). The results showed that in one growing season giving some doses cocoa's shell biochar had not been able to affect soil aggregate stability. The highest aggregate stability was found at treatment of 15 t ha-1 of cocoa’s shell biochar with an index of 130.12. The increased levels of soil organic C was followed by the increase in aggregate stability index. The highest organic C was found at D40 treatment with 4,09%. While the highest retention of water was found at the D10 with 32,96%. The increased aggregate stability index was not followed by the ability of soil to retain water. The addition of cocoa's shell biochar could increase soil organic C but not in line with the ability to retain water. If cocoa's shell biochar was given at the hig dose then it can give high maize yield.

Abstract

Mercury is one of heavy metals that is highly dangerous as it affects human health when it pollutes soils used for growing plants. The purpose of this study was to examine the potential of Brassica oleracea, Brassica rapa, and Brassica juncea in reducing levels of mercury in mercury-contaminated soil. Each of the three plant species was grown on a 3 kg of soil in a polybag which first contaminated with four concentrations of mercury (0 ppm, 0.5 ppm, 1 ppm, and 1.5 ppm ). The results showed that Brassica rapa accumulated mercury better then Brassica oleracea and Brassica juncea. On the soil contaminated with the lowest mercury concentration (0.5 ppm ), Brassica rapa root was able to absorb 0,081 ppm of mercury, at the concentration of 1 ppm, Brassica rapa root was able to absorb 0,091 ppm of mercury, while at the highest mercury concentration (1.5 ppm), Brassica rapa root was able to absorb 0,311 ppm. The ability of Brassica juncea roots to absorb mercury were better than those of Brassica rapa and Brassica oleracea.
