Plant spacing and pruning effect on yield productivity of jatropha
Arunyanark Anuruck,Foytong Kanniga,Jompuk Choosak,Srinives Peerasak,Tanya Patcharin 한국작물학회 2024 Journal of crop science and biotechnology Vol.27 No.4
The study examined the effect of plant spacing on yield productivity and assessed yield after pruning for jatropha. The experimental design was split-plot in a randomized complete block, including two main-plots of planting space comprised of 1×1.5 m (S1) and 2×1.5 m (S2), and 14 sub-plots were jatropha varieties of 11 interspecific hybrids crossed between jatropha and peregrina, and three jatropha varieties with four replications. The data collection was done continuously for two years and found that planting space was not significantly different in traits. In year one, S1 showed a higher value of fruit yield ha−1 and seed yield ha−1 than S2, while in year two, S2 displayed a higher mean, fruit weight plant−1 , and seed weight plant−1 than S1. The inter-specific hybrid jatrophas, KUJL70 and KUJL106 gave more seed yield ha−1 and oil content than other jatropha breeding lines.

This work was conducted to identify mungbean genotypesshowing yield stability and resistance to mungbeanyellow mosaic virus (MYMV) disease. Sixteen genotypes were evaluated in a randomized complete block design with two replications for two years (2011 and 2012) at three locations (Gazipur, Ishurdi and Madaripur) of the Bangladesh Agricultural Research Institute. An analysis of variance exhibited significant effects of genotype (G), environment (E), and genotype × environment (G×E) on grain yield. Among eight agronomiccharacters, the principal component 1 (PC1) was always higher than the PC2. Considering G×E interaction, BM6 was the best genotype at all three locationsin both years. Based on grain yield and stability performance, BM6 ranked first while the worst performinggenotypes were BM1 and G10. Based on discriminationand representation, Gazipur was identified as an ideal environment for these mungbeans. Relationshipbetween soil-plant analysis developments (SPAD) value was positive with yield but negative with MYMV severity. BM6, G1 and G2 were considered as promisingsources of resistance for low disease score and stable response across the environments. The environment proved to have an influence on MYMV infection under natural infestation. A positive correlation was observed between disease score and the temperature under naturalgrowing condition.

This work was conducted to identify mungbean genotypes showing yield stability and resistance to mungbean yellow mosaic virus (MYMV) disease. Sixteen genotypes were evaluated in a randomized complete block design with two replications for two years (2011 and 2012) at three locations (Gazipur, Ishurdi and Madaripur) of the Bangladesh Agricultural Research Institute. An analysis of variance exhibited significant effects of genotype (G), environment (E), and genotype ${\times}$ environment ($G{\times}E$) on grain yield. Among eight agronomic characters, the principal component 1 (PC1) was always higher than the PC2. Considering $G{\times}E$ interaction, BM6 was the best genotype at all three locations in both years. Based on grain yield and stability performance, BM6 ranked first while the worst performing genotypes were BM1 and G10. Based on discrimination and representation, Gazipur was identified as an ideal environment for these mungbeans. Relationship between soil-plant analysis developments (SPAD) value was positive with yield but negative with MYMV severity. BM6, G1 and G2 were considered as promising sources of resistance for low disease score and stable response across the environments.
