Cereal-legume intercropping can potentially increase yield of the intercropped cereals such as maize and rice. The aim of this research was to examine whether relay-planting peanut between rows of several promising lines of red rice could increase growth and yield of irrigated aerobic red rice. The Split Plot design was used to arrange the experiment consisting of three blocks and two treatment factors. The main plot factor was red rice line comprising four genotypes (G04, G10, G15 and G21) while the subplot factor was intercropping comprising two treatments (T0= monocropped rice, T1= rice-peanut intercropping). The results indicated that the rice-peanut intercropping could significantly increase red rice growth and yield while different lines only affected plant height and some yield variables. However, plant height and grain yield showed significant interactions of the treatment factors, in which G21 intercropped with peanut had the highest yield (47.16 g/clump equivalent to 9.34 tons/ha), while the lowest yield was on monocropped G04 (21.55 g/clump equivalent to 4.31 tons/ha). These indicated different responses among the red rice lines to additive intercropping with peanut, in which G21 showed the highest yield increase, followed by G15 and G04, while G10 showed no significant yield increase due to intercropping.

Additive intercropping with peanut increases growth and yield of various promising lines of red rice under aerobic irrigation system on permanent raised-beds

“…Both have the same strong influence on grain yields. According to [39] said that the correlation coefficient which shows a large number close to +1 means that it has a close relationship between the observed characters. The maximum number of offspring with a P-Value of 0.049 with a correlation value of 0.446 can be said to have a significant effect on a rather weak correlation.…”

One of the obstacles to increasing rice productivity in paddy fields in Tabanan district is the availability of adaptive new superior varieties (NSV) with high productivity. The aim of the study was to determine the agronomic performance, yield components and seed production of three NSV lowland rice which have the potential to be developed in irrigated paddy fields at Subak Guama Tabanan districs, in collaboration with AIAT Bali as NSV seed providers. The study was conducted from February to June 2021. The study used a randomized block design (RBD) with 1 factor 4 treatments including Ciherang as a comparison and each treatment was repeated 6 times. The collected data were analyzed using analysis of variance (ANOVA), then the treatment was further tested using the Tukey test at 95%. The results of the study showed that the application with a 2:1 legowo cropping system can increase the performance and components of crop yields. The use of NSV and the 2:1 legowo planting method can increase productivity by an average of 1.24 tonnes/ha of harvested dry grain (HDG) or an increase of 19.36% tonnes/ha of HDG. The application of ICM using NSV, the legowo 2:1 planting method is one way to increase rice production.

“…Correlation coefficient that shows a large number close to +1 or -1 can be used as the basis for selection criteria. This is because the correlation coefficient, which shows a large number, means that it has a close relationship between the observed characters [17].…”

By expanding the harvest index from 2 to 3 or even up to 4 harvests in a year, Salibu aims to boost land production. Using the legowo cropping system, two rows of rice plants are planted together to create a large chamber that extends in one direction. In order to determine which varieties are best for rice’s Salibu and to establish a pattern of relationships between characteristics and grain weight yield per clump of rice plants, this study will examine the physiological and growth characteristics of the five rice varieties in the first Salibu of the Legowo planting system. This study used a split-plot design with four replications and a fundamental design of Fully Randomized Block Design (CRBD) in Karang Tengah Village, Purbalingga. Inpago Unsoed 1, Inpari 24, Inpari 32, Inpari 43, and Logawa were the kinds that were used. The findings demonstrated that the amount of chlorophyll, flowering duration, and panicle length were significantly influenced by variety. Stomatal density, the number of active tillers, and the number of grains were traits that were tightly connected and had a significant direct impact on yield. Consequently, these traits could be employed as selection indications for rice with high yield.
