Abstract

A research entitled the effect of various sources of organic matter on improvement of N,P,K Nutrient of Ultisol was conducted in Limau Manis Padang. The research was aimed to investigate the contribution of different source of organic matter to improve N,P,K content in soil. Field research was arranged in Randomized Block Design (RBD)  consisting 5 treatments and 3 replications (blocks). Treatments are : A = no organic matter added, B = Tithonia, C = Paddy Straw, D = Imperata cylindrica, and E = Leucaena glauca. The dosage for each treatment was 20 ton/ha. The result showed that tithonia gave the best contribution in improving N,P,K content of Ultisol Limau Manis.Keywords :organic matter, N, P, K of Ultisols.

Abstract

The endophytic bacteria are bacteria whose life cycle is partially or completely associated in the host plant tissue in various kinds of relationships (symbiosis) that it undergoes. The potential of endophytic bacteria as microbial resources is widely used as a biological control for plants, including as the producer of phytohormones and the agent of biocontrol and biofertilizer. This study aims to test selected endophyte bacterial isolates from chili as a biofertilizer to meet the nutrient requirements that are useful during the vegetative growth period of red chili in Ultisols. The study used a completely randomized design with 4 treatments and 3 replications, namely A = fertilizer N  recommendation; B = Azospirillum sp AK+ Fertilizer N recommendation; C = Azospirillum sp BT+ Fertilizer N recommendation; D = Azospirillum sp DN+ fertilizer N recommendation. Azospirillum sp AK and Azospirillum sp DN isolates gave better vegetative growth than those of Azospirillum sp BT isolates with average dry weight, respectively, 19.49 g and 18.93 g and with a height of 29.67 cm and 29.60cm. The superiority of the 2 isolates was also shown in the observation of the number of leaves 30.39 and 22.50 and the number of branches 6.45 and 6.28 respectively for Azospirillum sp AK and Azospirillum sp DN isolates.Key words : Endophytic bacteria, red chili, Ultisols

Abstract

A research about amelioration of psycho-chemical of Psamment by using organic mulch and techniques of conservation tillage on corn growth had been conducted in 2009. Field experiment was located in Korong Olo Bangau, Batang Anai, Padang Pariaman Regency. The general objective of the research was to improve fertility of Psamment and to find out the best tillage practice for corn growth based on soil and water conservation rules. The treatment consisted of two factors (3 x 5) which was designed in RBD. The first factor was tillage (No till, Minimum till, convensional till) and the second factor was mulch source (without mulch, Tithonia, Chromolaena, rice straw, and corn straw). Parameters analysed were either soil physical (moisture, BD, total pore, aggregation) or chemical (pH, N, P, and K) properties, as well as crop production. The result showed that both treatments were able to improve soil-physico-chemical properties of Psamment and corn yield. The value of BD decreased, soil organic mattere, total pore, and aggregation increased. Then, the soil pH as well as available P and K tended to increase. The highest yield (dry seeds) was found from combination between minimum tillage and tithonia mulch.Keywords: sifat fisiko-kimia, Psamment, mulksa, olah tanah konservasi, jagung.
