Rice is the most essential staple food of Indonesian. The strategy to meet these food needs is through efforts to increase productivity by means of agricultural intensification. One of efforts to increase productivity is the application of integrated technology using the System of Rice Intensification (SRI) method and organic cultivation. The research was conducted from March to June 2017 in Sambirejo, Sukorejo, Sragen. Forty rice varieties originating from the Center for Rice Research, Sukamandi, Subang, West Java were tested in this study. Planting was carried out by transplanting using 1 seedlings of 15 days after dispersing (HSS) / planting hole on a plot measuring 2 m x 2 m with a spacing of 20 cm x 20 cm. The research was organized using a completely randomized block design with four replications. Cultivation techniques are carried out organically with guidelines for integrated plant management. Observations were made on the character of the agronomic performance and yield. The results of the analysis of variance showed that there were differences between the varieties tested on all agronomic characters and yields. Varieties that responded well to organic land with the SRI system at the study site were Membramo, Sintanur, Inpari 13, Inpari 32 and Inpari 5 Merawu varieties, while the varieties that responded poorly to the study were Batutegi and Lusi varieties.Padi merupakan makanan pokok masyarakat Indonesia yang mutlak harus terpenuhi.

Application of system of rice intensification (SRI) method has been considered as one of powerful efforts to increase the harvested yield by modifying the plant and itssurrounding environment. This study was aimed to determine the effect of different environment towards the response of rice varieties grown using SRI method. Two rice varieties, Batang Piaman and IR-42 were grown in District of Tanjuang Barulak (Regency of Tanah Datar) and District of Saniang Baka (Regency of Solok). Plant height and several yield parameters, such as productive tillers, panicle length, grain number per panicle, and yield per plot were assessed from both varieties and locations. Statistical analysis was conducted using randomized block design (RDB) and significance was further evaluatedusingDuncan’s New Multiple Range Test (DNMRT) with a p>0.05. Batang Pariaman appeared in taller performance than IR-42. Regarding the number of productive tiller, Batang Piaman resulted more productive tillers in Solok, while IR-42 was dominant in number of productive tiller compared to Batang Piaman in Tanah Datar. Unlike IR-42, Batang Piaman exhibited longer panicle, more grain amounts per panicle, and higher yield per plot than IR-42 in both locations.

Increasing rice productivity has been the main priority for the Government of Indonesia to meet people's food needs, however, there are a number of obstacles such as technology adoption. This study aims to explore the condition of farmers' cultivation, especially in terms of planting systems, varieties developed and reasons for selecting varieties in three different land topographic types (low, medium, and high). Sampling was done purposely with a total sample of 45 farmers who cultivate rice. Data collection includes observation and structured interview, data were analyzed descriptively. The results showed that most of the planting system that developed in three types of topography is the ‘tegel’ planting system, other technologies such as “jajar legowo” and system of rice intensification (SRI) have low developed. This is influenced by the new planting system need more skilled labor, more expensive input, and lack of farmers' knowledge. Local rice varieties have declined significantly, dominated by certain superior varieties. The main reason for selecting varieties is due to high productivity and disease resistance. In addition, the accessibility of rice seeds by farmers at the nearest farm shop. This research suggested more intensive mentoring efforts should be done through farmers’ group meetings and improvement of supporting facilities, furthermore the Local Government should improve farmers' affordability of quality seeds.

Participatory action research was conducted in Luinyata VDC of Bajhang district during main rice-growing season of 2012 to evaluate the effects of cultivation practices in rice varieties. The experiment was in factorial randomized complete block design, where two methods of cultivations: System of rice intensification (SRI) and conventional transplanting (CT) and 3 different varieties: Khumal-4, Thapachini and Hansaraj Basmati were evaluated. Data were collected on grain yield, number of tillers, panicle length and number of filled and unfilled grains per panicle. Results averaged across the three varieties showed significantly better crop performance with SRI practices: higher number of tillers per hill, panicles per hill, tillers per m2, panicles per m2, and grain yield. The values of these parameters comparing SRI with conventional practice were, respectively, 24.5 vs. 11.3, 21.5 vs. 9.5, 305 vs. 273, 273.5 vs. 233.8, and 7.6 vs. 4.46 tha-1. Among the varieties evaluated, the highest yield was achieved with the Thapachini (8.11tha-1) using SRI methods. Average yield increase across the three varieties with SRI practice was 70% compared CT. These results indicate the practical relevance of SRI principles for increasing rice production in mountainous regions of Nepal.

Crop Sustainability

Restoration of soil has been identified as the option; to ensure crop sustainability. However, as per Trophobiosis Theory of French Scientist F. Chaboussou, focus on development of healthy plants is necessary to abate pest and disease invasion so as to ensure sustained crop performance, even under unfavorable environmental conditions. The present study, in randomized block design with green gram as test crop; was undertaken in Krishi Vigyan Kendra (Howrah, West Bengal) to evaluate the effectiveness of Inhana Rational Farming (IRF) Technology towards crop yield and soil quality development under different sustainable models viz. organic cultivation, integrated soil with organic crop management and non- chemical crop management; as compared to conventional farming practice. Highest yield was recorded under organic (933 kg ha-1) followed by integrated (921 kg ha-1) and non- chemical plant management (902 kg ha-1). The results were well corroborated with the plant development index obtained under these treatments. Favorable trend of soil quality under sustainable models especially in terms of microbial properties indicated the role of quality compost towards speedy rejuvenation of soil dynamics. The study indicated that reduction of synthetic fertilizers and qualitative management of soil is essential to restrict yield decline. However, plant management shall be prerequisite for ensuring crop sustainability without any time lag and under the changing climatic patterns. In this respect the potential of IRF Technology has been well accounted.
