Rice is a rice-producing food crop which now plays an important role in economic life in Indonesia. Namely rice as a staple food is very difficult to replace by other staples. Among them are corn, tubers, sago and other carbohydrate sources. So that the existence of rice is now a top priority for the community in meeting the needs of carbohydrate intake that can be filling and is a source of primary carbohydrates that are easily replaced into an energy source. Rice as a staple food is consumed by approximately 90% of the total population in Indonesia for daily essential food (Saragih,2001). How to plant with the jajar legowo system has the advantage that the plants are on the edge so that optimal sunshine can cause plant productivity to be high, facilitate weed control and pests / diseases, use of fertilizer more effectively and the availability of empty space for regulating water channel circulation on land (Sirrapa, 2011). This research was conducted using Factorial Randomized Block Design (RBD) method, which consisted of two factors and each factor consisting of 3 levels repeated 3 times, namely: J1: Conventional,J2: Jajar Legowo 2: 1,J3: Jajar Legowo 4: 1. Factor II: Varieties with 3 levels, V1: Situ Bagendit, V2: Ciherang,V3: IR-64. Of the two factors 9 combinations of treatments were obtained and repeated 3 times. Data obtained from observations were calculated by analysis of variance with the Fisher test (-F test at the level of 5% and 1%), if there were significant differences, it would be followed by the Smallest Significant Difference test (LSD 5%). The treatment of the legowo 4: 1 row system and the ciherang variety (V2J3) produces a better value than other treatments.

Rice is the main staple food in Indonesia. The high needs of national rice must be balanced with the high production of rice crops. One of the efforts to increase the production of rice is the application of liquid smoke originated from agricultural waste, namely husk. The research was aimed to determine the effect of the application of husk liquid smoke on rice growth and production. The research used a single-factor randomized block design (RBD) with 5 treatments and 5 replications. The treatments consisted of several concentrations of liquid smoke : 0% (control), 0.5%, 1%, 2%, and 3%. This research employed several stages; land processing, seedling nursery, rice planting, applicating the liquid smoke, fertilizing, maintaining plants, and harvesting. The results showed that the application of husk liquid smoke significantly affected all observational parameters. On the parameters of rice growth and production, the application of 2% liquid smoke showed the best result. The plant height increased by 25.80% and the number of tillers increased by 49.70% compared to the control. The highest increase is in the number of grains per panicle and the weight of 1000 grains was 4,984% and 26.78% respectively.

Effect of nitrogen and bio-fertilizer on growth and productivity of hybrid rice (cv. PHB 71) was assessed during dry seasons of 2017 and 2018 at Research Farm of BCKV under new alluvial zone of West Bengal. The experiment was laid out in factorial randomized block design with 12 treatment combinations having 4 levels of N and 3 types of bio-fertilizer replicated thrice. Application at 180 kg N/ha produced tallest plants at 90 DAT with maximum LAI (60 DAT), DMA (90 DAT), tillers/hill (90 DAT) and CGR (30-60 & 60-90 DAT). The same N rate resulted in highest panicles/m2, panicle length, panicle weight, filled grains/panicle and 1000-grain weight. A decrease in N dose from 180 to 150 kg/ha caused reduction in all those yield components; however, the variation was non-significant except for number of panicles/m2. Maximum grain yield, straw yield and harvest index was also achieved with 180 kg N/ha accounting 120.1, 34.9 and 32.8% more than the values obtained with zero-N; however, it was statistically at par with the yields and HI obtained with 150 kg N/ha. The Azospirillum application increased all the growth parameters, yield components and yield of hybrid rice over other tested bio-fertilizers (Azospirillum > PSB > K mobilizer), accounting 5.9 and 8.8% more than the yields obtained with PSB and K mobilizer. The interaction of N and bio-fertilizer exerted significant effect on growth attributes but failed to record any significant variations in yield components and yield of hybrid rice. The maximum economic benefit was achieved with combined application of 180 kg N/ha and Azospirillum.
