Super paired rows planting technology (Jarwo Super) is an integrated rice cultivation technology on irrigated rice field based on 2:1 paired rows designed to improve rice yield. The super 2:1 paired rows is defined as crop planting technique where by every two rows of rice plants was followed by one blank row and to be repeated for the next row arrangement. The technology super 2:1 paired rows consisted of: (1) improved variety; (2) bio-decomposer; (3) inorganic fertilizer and biofertilizer; (4) biopesticide and chemical pesticides; and (5) the use of agricultural machinery. The objective of this study was to determine the technical feasibility, financial feasibility, and the sensitivity analysis of the adopter of Jarwo Super farmers to be compared with the traditional planting farmers. The research was carried out in three provinces: Aceh Province, North Sumatra and South Sumatra Province. Data were collected using survey method using the structured questionnaires involving 267 Jarwo Super farmers and 214 traditional planting farmers. Results showed that rice yield obtained from the Jarwo Super adopter increased by 31% in Aceh, 37% in South Sumatra and 12% in North Sumatra. The cost allocation for Jarwo Super cultivation was about 37.19% and for the traditional planting farmers was 43.59%, the values of each R/C ratio was 2.69 and 2.29 and the B/C ratio was 1.69 and 1.29, respectively. The value of MBCR is 5.25 which mean the introduction of Jarwo Super technology was financially feasible. The sensitivity analysis indicated that the Jarwo Super technology was not sensitive to the changes of price and rice yield.

<p>Water and fertilizer scarcity amid the increasing need of rice production challenges today’s agriculture. Integrated crop management (ICM) is a combination of water, crop, and nutrient management that optimizes the synergistic interaction of these components aiming at improving resource use efficiency, i.e. high productivity of water, land, and labor. The objectives of the study were to investigate the effects of crop establishment method, organic matter amendment, NPK management, and water management on yield of lowland rice. Five series of experiments were conducted at Sukamandi and Kuningan Experimental Stations, West Java. The first experiment was focused on crop establishment method, i.e. plant spacing and number of seedlings per hill. The second, third, and fourth experiments were directed to study the effect of NPK and organic matter applications on rice yield. The fifth experiments was designed to evaluate the effect of water management on rice yield. Results showed that 20 cm x 20 cm plant spacing resulted in the highest grain yield for the new plant type rice varieties. Organic matter and P fertilizer application did not significantly affect grain yield, but the yield response to P fertilization tended to be stronger with organic matter amendment. Split P application did not significantly increase grain yield. The use of a scale 4 leaf color chart reading resulted in a considerable N fertilizer saving without compromising rice yield. Intermittent irrigation technique saved water up to 55% without affecting yields, resulting in a 2-3 times higher water productivity.</p>

The diverse sources of agricultural extension information do not guarantee increased farmers’ capabilities to adopt agricultural innovations. Consequently, efforts to accelerate the adoption of agricultural innovations should pay particular attention to farmers’ compatibility with different information sources. This study aims to analyze farmers’ perceptions of various information sources about rice commodity innovations and determine the information sources influencing farmers’ capabilities in adopting rice innovations. The study was conducted from June to December 2019 through a structured survey approach with 270 rice farmers in Subang, West Java and Boyolali, Central Java, Indonesia, by using structural equation model analysis. The results showed that rice farmers had positive perceptions of government, private, and self-subsistent extension. The capability level of rice farmers showed that all indicators were significantly different. Farmers could improve their capabilities and sustainability of rice farming by adopting agricultural innovations. Information from government and private extension providers had a positive effect on the capacity and capability of rice farmers. The role of self-subsistent extension was more of a facilitator and did not directly affect the capacity and capability of farmers. Participatory extension activities are recommended as a form of intervention that can improve rice farmers’ capacity and capability in terms of technology adoption processes. The extension activities should be provided as a series, rather than one-off events, so that farmer knowledge accumulates over time through a style and pace to match their skills and level of education.
