Abstract

East Nusa Tenggara is a classified as semi-arid with short rainy month and the soil is generally less fertile. One of the land management efforts with existing condition is the application of biochar and mycorrhizae. The aims of this study were to investigate the effect of biochar combined with mycorrhizae to incrase maize resistance to drought and yield of maize. This study was designed in a randomized block design (RBD) with 12 treatments including; Biochar + AMF daily watering, Biochar + AMF every two days watering, Biochar every three days watering, Biochar daily watering, Biochar every two days watering, biochar every three days watering, AMF daily watering, AMF every two days watering, AMF every three days watering, Without Biochar and without AMF daily watering, Without Biochar and without AMF every two days watering, and Without Biochar and without AMF every three days watering. There were three replicates for each treatment. Variables observed were soil water content, organic C, total-N, available P, exchangeable K, weight of cobs without cornhusk and weight of cobs with cornhusk The results showed that the application of biochar and mycorrhizae with daily watering had a significant effect on cob weight without cornhusk. The application of biochar and AMF gave better soil water content, total N, available P, exchangeable K, and cob weight with and without cornhusk compared to the treatment without biochar and wthout AMF

Abstract

Dryland farming in Timor island is always constrained with the shortage of water supply, soil fertility as well as the availability of nutrients especially Phosphor (P). This condition can be eliminated by application of organic matterial to soil, because organic matter can increase the soil’s ability to hold water and soil fertility. Biochar as an organic material has been proved to increase soil water holding capacity and able to adsorb nutrients to prevent it from leaching. This research aimed to study the effect of combination of biochar and water supply on the availability of P in soil, uptake P by plants and yields of Turnip planted ini calcareous soil of Timor . This research is designed using Completely Randomized Design (CRD) and it is a single factor trial. There are 7 treatments of a combination of rice husk biochar dosage and volume of water supply. The results showed that there is a significant effect of the combination of rice husk biochar dosage and volume of water supply on the availability of soil P and the weight of radish tubers. Application of 300 gram.polybag-1 of biochar + 90% Etm of water supply gave higher available P (87,22 ppm), while application of 300 gram.polybag-1 of biochar + 80% Etm of water supply gave a better fresh weight of tuber (305,00 g ) compare to other treatments.
