Abstract

ABSTRACTRice as a staple food for most of Indonesia's population,their needs increase withincreasing population, conversely production decreases. One effort to meet theneeds of rice is by planting upland rice in dry land. Ultisol is the most extensivedry land in Indonesia. The yield of upland rice in Ultisol is very low, this iscaused by various problems including acid reaction, high Al saturation and Pfixation, availability of macro nutrients (N, P, K, Ca, Mg), low micro nutrients(Mo). Rice husk ash and natural phosphate can be used to increase pH andnutrient availability. The purpose of study was to study the effect of the interaction of rice husk ash and natural phosphate in increasing the growth andyield of upland rice (Oryza sativa L.) on Ultisol medium. The study was conducted at the Faculty of Agriculture greenhouse, University of Riau fromMarch to July 2019. The research was an experiment in the form of a 4x3 factorial using a completely randomized design. The first factor consists of four levels of rice husk ash (0.0; 1.5; 3.0; and 4.5 tons ha-1), the second factor of natural phosphate consists of 3 levels (0, 25 and 40 kg P2O5 ha-1), each repeated three times. The results showed the interaction between rice husk ash with a dose of 1.5 tons ha-1 and natural phosphate with a dose of 25 kg P2O5 ha-1 increased plant height, number of productive tillers, panicle length, number of paddy grains with pan, paddy grains and dry grain weight milled compared without rice husk ash and natural phosphate, each of these parameters tends to increase higher at the highest dose (4.5 tons ha-1 rice husk ash and 40 kg P2O5 ha-1 natural phosphate).

Abstract

ABSTRACTThe main problems of rice cultivation in Ultisol medium are acid reactions, Al saturation and height P fixation, as well as low availability macro, micro nutrients especially Mo and Si. Rice plants need silicate in large quantities even though it is not an essential nutrient, therefore husk ash can be used as a source of Si. Pavailability increased by applying P fertilizer which was classified as slow realease so that fixation can be supported. The research aims to study the interaction of rice husk and rock phosphate is able to improve Si and P uptake and the growth of upland rice growth on Ultisol medium. The research was conducted at the Green House of the Faculty of Agriculture, University of Riau, Pekanbaru from January to March 2019. The research in form factorial experiment 4×3 was arranged in a completely randomized design, 3 replications. The first factor wasrice husk consist of 4 levels (0, 1,5, 3, and 4,5 ton ha-1). The second factor wasrock phosphate consist of 3 levels (0, 25, 40 kg P2O5 ha-1. The results showed the application of rice husk dose of 3 ton.ha-1 and rock phosphate dose of 25 kg P2O5 ha-1 increased Si and P uptake, P uptake efficiency, the root volume, dry weight, root canopy ratio, and plant growth rate.

Abstract

Rice commodities are the main food and are widely planted in Pulau Rambai Village, Kampa District, Kampar Regency. Pest attacks are the main obstacle in cultivating rice. The concept of integrated pest management (PHT) is applied to rice farmers. This management includes combining compatible pest management techniques, prioritizing natural management using natural enemies. This activity aims to provide counselling, assistance and guidance to rice farmers to implement PHT to increase the quantity and quality of rice production. The intended target was rice farmers in Pulau Rambai Village. The method of implementation carried out is counselling, mentoring and assisting. Counselling is in the form of presentation on farmers' paddy farms introducing the concept of PHT, management of plant cultivation that is not suitable for rice pest development, the introduction of natural enemies of pests, and types of environmentally friendly control such as vegetable pesticides and biological agents. Guidance and mentoring were also given to farmers in monitoring pests, natural enemies, and rice ecosystems. The level of achievement of the program targets was monitored from the questionnaire filled out by farmers before counselling and at the end of the mentoring activities program. From the questionnaire, there was a change in the views and knowledge of farmers in the concept of pest control. The program's achievement is also seen from the change in cultivation methods such as the legowo 4x1 system with three seeds per clump and pest control using biological pesticides according to the guidance.
