One of the cultivation technologies that need to be considered in increasing rice production is the proper use of fertilizer. This study is to find out the substitution of NPK fertilizer with rice straw bokashi to the growth and yield of rice paddy plants cisantana varieties. This research was conducted from August to November 2020 in Samaku Village, Bualemo District, Banggai Regency. The method used is a RandomIzed Design Group (RAK) factorial pattern consisting of 2 factors, namely factor A (NPK fertilizer) and factor B (Straw Bokashi). The combination of NPK fertilizer and rice straw bokashi has no natural effect on rice paddy plants of Cisantana varieties. Still, it has a natural impact on grain dry weight per plot. The treatment of rice straw bokashi independently has a noticeable effect on the height of the plant, the number of saples, the number of productive saples and the length of the panic. The bokashi straw rice dose of 75% (3.75 tons/ha) is the best dose for high plant growth, number of saples, number of productive saples and malai length. While the dose of 75% NPK (187.5 kg/ha) + 75% bokashi rice straw (3.75 tons/ha) is the best combination dose for varied dry weight of grain per plot.

The objective of this research was to investigate the effectiveness of combination of bio-slurry fertilizer and NPK fertilizer on the growth and production of two varieties of rice. The experiment was assigned in a completely randomized design of factorial pattern. The first factor was the combination of bio-slurry and NPK fertilizer that consisted of P0 = no added fertilizer (control) 0 ton/ha, P1 = NPK fertilizer 550 kg/ha (165 kg N, 33 kg P, 45 kg K); P2 = bio-slurryfertilizer 2.3 tons/ha (45 kg N, 14 kg P, 23 kg K) and NPK fertilizer 400 kg/ha (120 kg N, 24 kg P, 32 kg K); P3 = bio-slurryfertilizer 4.6 tons/ha (90 kg N, 28 kg P, 46 kg K) and NPK fertilizer 250 kg/ha (75 kg N, 15 kg P, 20 kg K); P4 = bio-slurry fertilizer 5.9 tons/ha (115 kg N, 36 kg P, 59 kg K) and NPK fertilizer 100 kg/ha (30 kg N, 6 kg P, 8 kg K); and P5 = bio-slurryfertilizer 8.5 tons/ha (165 kg N, 52 kg P, 85 kg K). The second factor was varieties of rice that consisted of V1 : IR-64 and V2 : Ciherang. Each treatment was repeated three times. Parameters observed were plant height, number of tillers, weight of 1.000 grains, and rice production. Data were analyzed using ANOVA and continued with Duncan’s Multiple Range Test (DMRT). The results showed that the combination of bio-slurry fertilizer and NPK fertilizer were significantlyaffect (p <0.05)all observation parameters, while varieties of wetland rice did not show significant effect on all observation parameters (p<0.05). The application of bio-slurry fertilizer in single treatment or in either combination with NPK fertilizer had the same result with the treatment of NPK fertilizer on the growth and yield of rice.

Beneficial Elements

Background: The beneficial elements availability such as silicon was determined rice growth and yield. Rice requires a different dose of silicon during the growing period. Experiment was aimed to investigate the effect of silicate levels, rice varieties and the interaction of the two on the growth and yields of two local Indonesian varieties of rice. Methods: A completely randomized design of factorial pattern with 4 replications was used in the experiment. Treatments consisted of No added SiO2 (Si-0); added 100 and 200 kg SiO2 ha-1, respectively for Si-100 and Si-200 and two local rice varieties, Pandan wangi (P1) and Mentik susu (P2). Result: The treatment had no significant effect on growth and yield of rice. Addition of 100 and 200 kg SiO2 ha-1 to P1 and P2 did not show a significant difference on the growth and yield of rice compared to control (P0). Plant height and root dry weight at P1 was lower than P2, but the 1,000-grain weight was showed, vice versa. Silicon addition up to 200 kg SiO2 ha-1 may not be recommended to be applied in rice cultivation, especially Pandan wangi and Mentik susu varieties. Improving the two varieties, further research is needed by increasing the silicon doses.

Abstract The conservation of natural resources like soil and water and reduces chemical pollution in the environment is the desired goal of the directions of improving the performance of important crops for meeting the global food demand. However,System of Rice Intensification (SRI), is a rice cropping system that is consistent with Conservation Agricultural (CA) and Sustainable Agriculture (SA). The current study was aimed to investigate the effects of SRI method on grain yield and its components in two rice varieties compared with conventional practice in farmers' fields (CFM) in different environmental conditions in Iraq. The study was conducted in the fields during the rice season 2019 in three provinces in the south of Iraq (Najaf, Diwaniya and Muthanna). Anber33 and Jasmine rice varieties were grown in each location and the traits were conducted at sites having 2 donum of land (5,000 m2).The trial was performed as a factorial experiment based on a randomized complete blocks design (RCBD) having three blocks. The results showed superior significant of SRI method compared to CFM method in traits (plant height and panicle length, number per panicle, and percentage of unfilled grains). Furthermore, SRI method gave higher grain yield as a percentage with both varieties in each province (25.6% in Muthanna, 24.5% in Najaf, and 13.2% in Diwaniya province) compared to CFM. However, grain yield in Jasmine variety was higher than on Anber33 approximately 50% in three locations in this study. Overall, our results suggest that SRI method is the most convenient method in Iraq conditions due to the increased grain yield in rice compared to the CFM method.
