Growth, yield and quality of sorghum [Sorghum bicolor (L.) MoenchJ as influenced by planting densities, genotypes and different levels of nitrogen

摘要

Field experiment was conducted during summer season of 2006 at Research Farm of College of Agriculture, Indore, Madhya Pradesh to investigate the effect of plant density, genotypes and nitrogen levels on cane and grain yield of sweet sorghum. The results showed that the higher grain yield (2427 kg/ha) along with cane yield and juice yield was recorded under plant density 45 cm x 15 cm. Plant density of 45cm x 15cm gave higher gross returns (Rs 37592/ha), net returns (25871/ha) and benefit cost ratio(3.21). Among the genotypes, NSSH-104 was found better in respect of all the growth characters as well as yields attributing characters and yield. A positive correlation was observed between the growth, yield attributes and yield along with higher levelsof nitrogen applied. Application of 120 kg N/ha was found suitable and recorded the maximum yields and monetary returns and benefit cost ratio.
