Evaluation of garlic (Allium sativum) genotypes for yield and susceptibility to purple blotch

Twenty one genotypes of garlic (Allium sativum L.) were screened for yield and purple blotch susceptibility under field conditions for two years. Reaction of genotypes to purple blotch disease differed significantly during both years but the pooled analysis revealed that most of the variations were due to genotype × environment interaction. Nine genotypes viz., G-1, G-50, G-323, PGS-4, PGS-14, G-313,...

Improved model for estimation of leaf area index using airborne laser profiling

The study was conducted to derive a functional relationship between airborne laser generated forest profile area and ground-based leaf area index (LAI) for extensive estimation. Subsequently, LAI was estimated by applying parameterized derived equations to the laser data covering a 384 ha temperate forest in Ehime, Japan. There is a growing demand for accurate estimates of LAI in larger areas due to its role in...
