Abstract Rice productivities in the swamp radish area is still in low category. It needs to introduce technology innovation through integrated crop management approach. Adopting technology innovation process needs farmer’s behaviour changing. Farming instructor has strategic role in changing of farmer behaviour. There are many methods can be used, one of them is Aplply Experiment in effort technology dissemination Indonesian Agency for Agricultural Research and Development, do a studying applicating swamp rice cultivation to improve farmer behaviour. This paper aim to (1) to measure farmer’s knowledge and behaviour in swamp rice cultivation using PTT approach. (2) to evaluate farmer’s applying level in rice swamp cultivation using PPT approach. (3) to analyse relation between farmer’s knowledge and  behaviour in rice swamp cultivation using PTT approach. This research has been done on December 2020 in Pemulutan village I, Ogan Komering Ilir district using survey method and interview using questioner. Being analysed descriptively and non-parametric Spearman Rank correlation. the result shows that most of respondents has known and agree  with swamp rice cultivation technology by PTT approach exception in fertilization frequency and fertilization based on PUTR and only 40% and 30% farmers know about each component . Most farmer’s absorbing level is in trying level and just few reach applied level. Spearman rank Relation test result shows a significant relation between knowledge and farmer’s behaviour with relation direction positively with  correlation coefficient is 1,00 and signification number is 0,000.

Lowland rice has a very important role in meeting national rice needs because around 90% of rice production comes from paddy fields. The aim was to determine the performance growth and production of the Inpari variety that is adaptive and high yielding in irrigated rice fields. Inpari 42 and Inpari IR Nutri Zinc are white label with comparison to Inpari 32. The need for fertilizer is 300 kg of Ponska NPK and 200 kg of Urea/ha. Observational data included: growth performance consisting of plant height, number of productive tillers, panicle length. The performance of the yield and yield components consisted of the number of grain/panicles, the number of full grain/panicles and productivity. Data were analyzed by means of equality test (t-test).  The results showed that the plant height of inpari 42 and inpari IR Nutri Zinc was relatively short while inpari 32 was classified as medium. The number of productive tillers and panicle length of inpari 42 and inpari IR nutri Zinc were not significantly different from inpari 32. The highest production of inpari 42 was 8.5 tons gkp/ha followed by inpari Ir nutri Zinc which was 7.0 tons gkp/ha better than comparison varieties.
