The study evaluated the adoption of System of rice intensification (SRI) among rice farmers in Chanchaga Local Government Area of Niger State, Nigeria. A 3-stage sampling technique was used to collect data for the study through a structured questionnaire and interview schedule administered to 200 rice farmers. The results indicated that the majority of the farmers were males (83.0%) and married (68.5%) with no formal education (50.5%). Mean age was 44.1 years, household size was 8.8 persons, farming experience of 16years, average monthly income was N590,000.00 and average farm size was 1.7 ha. The most adopted SRI production practice was fertilizer and herbicide application (100.0%), planting depth (91.5%) manual land cultivation and planting method (91.0%). The respondents were at different stages of adoption with accelerating growth, rotary weeding and use of organic fertilizer having positive adoption index of 0.972, 0.970 and 0.601, respectively. Level of adoption of SRI technologies was low (34.5%) with a positive perception. Major constraints to SRI technologies were high labor ( =3.27), non-awareness of SRI technologies ( =3.14) inadequate understanding of SRI ( =2.89). The profitability of SRI in rice cultivation was higher compared to the conventional method. Therefore, the provision of  more training and demonstration programmes and input subsidy should be encouraged to boost adoption of SRI for improved rice production.

This community service took place in Simatohir Village, Padangsidimpuan District Angkola Julu, Padangsidimpuan City. The implementation methods used are counseling methods, cultivation technique training, and mentoring. The approach method used is: a) Counseling about the application of SRI technology. b) Make demonstration plots or demonstration plots. c) Use of 2 : 1 legowo planting system using ticks. In the generative phase clearly visible results from the application of SRI are applied to the rice field cropping. There is a distance that facilitates the care of farmers, efficiency in the use of paddy water and the number of productive tillers is 25-40 tillers / clumps and the yield reaches 1337 tons with an area of ​​1000 square meters and this difference is very obvious when farmers do not use SRI , which starts from tillage which is only extracted, unbalanced fertilization, irregular irrigation, perforated plants between 10-20 plants with productive tillers only 15-23 tillers. This will have an impact on harvest yields which only reach 900 kg with an area of​​ 1000 square meters.

Four seeding rates (25, 30, 35 and 40 g/m2) of rice in nursery were tested for seedling vigour recorded at 10, 17 and 24 DAS at Malan during 2013 and 2014. The seedling vigour so obtained in nursery was subsequently evaluated in field during kharif 2013. Thus twenty four treatments comprised of combinations of three seedling ages (10, 17 and 24 days) and two spacings (20 × 20 cm and 20 × 15 cm) in main plots and four seedling vigour from four seeding rates (25, 30, 35 and 40 g/m2) in sub plots were evaluated in split plot design. Seedling shoot length under all seeding rates (25-35 g/m2) was significantly higher compared to check (40 g/m2) during 2013. In the next year, shoot and root length (30-35 g/m2), tiller per seedling and leaves per seedling (25-30 g/m2) of 24 days nursery was significantly higher over check (40 g/m2). Plant height, tillers, leaves and dry matter accumulation were significantly higher when younger seedlings aged 10 and 17 days were used. The crop raised using 10 days old seedlings matured 3-5 days earlier than 24 days old seedlings. Wider spacing resulted in more plant height, tillers, leaves and dry matter accumulation. Seedlings from 25, 30 and 35 g seed/m2 resulted in significantly taller plants than 40 g/m2. The seeding rate, seedling age and plant spacing did not significantly influence rice productivity thereby permitting flexibility to the rice farmers in the adoption of these factors.

<p>Excessive use of inorganic fertilizers mainly NPK causes soil degradation, environment pollution, decreases production, and reduces soil biological activity. System of rice intensification is one method of rice cultivation. SRI main principles are seed transplanting at young age (7-11 days old), transplanting use single seedling methode, seedlings at wide plant spacing ≥ 25x25 cm, intermittent irrigation and field conditions are not flooded, and reduction of chemical fertilizers and application of organic fertilizer. This research was conducted at Situgede Village, West Bogor District, Bogor. The research design was split plot randomized complete block design with three blocks. Two rice cultivation system as the main plot and five combinations of fertilizer application as sub plot. In the main plot consisted of two rice cultivation which is conventional and SRI while the subplot consisted of five combinations of fertilizer application is no fertilition, 100% inorganic fertilizers (Urea = 250 kg ha-1, SP-36 = 75 kg ha-1 and KCl = 50 kg ha-1), 75% inorganic fertilizers (Urea = 187 kg ha-1, SP-36 = 56.8 kg ha-1 and KCl = 37.5 kg ha-1) + 200 kg of bio-organicfertilizer, 50% inorganic fertilizers (Urea = 125 kg ha-1, SP-36 = 37.5 kg ha-1 and KCl = 25 kg ha-1) + 200 kg of bio-organicfertilizer and 50% inorganic fertilizers (Urea = 125 kg ha-1, SP-36 = 37.5 kg ha-1 and KCl = 25 kg ha-1). The results showed that SRI method produced maximum number of tillers higher that of 25.8 tillers/hill or an increase of 64.33% compared with conventional methods. Wet and dry shoot weight of wet and dry weight of root is greater in successive SRI method of 13.3%, 19.1%, 1.40% and 41.8% compared with the conventional method. The number of productive tillers, grain number/panicle, 1000 grains weight, root wet weight and dry grain at SRI method was higher than those in conventional method respectively 58.6%, 37.0%, 2.50%, 25.1% and 32.6%. The uptake of N and P in the SRI method higher at 72.0% and 100% compared to conventional method.
