A field experiment was conducted at Rice Research Unit, Bapatla during Kharif, 2013 to observe the performance of hybrids under Krishna Western Delta. The experiment was laid out in Randomized Block Design with four replications. The treatments are 5 rice hybrids like DRRH2, DRRH3, KRH2, PA6201 and CRHR32. The results of study revealed that the hybrids exhibited superiority in respect of different growth parameters like plant height, number of tillers per hill, panicle length grain yield and straw yield. Among various tested rice hybrids, maximum grain yield (6408 kg/ha) and straw yield (7178 kg/ha) were recorded in PA6201 which might be due to better growth parameters and yield components of hybrids.
A field experiment was conducted during Kharif, 2012 at Rice Research Unit, Bapatla to study the quality of rice affected by integrated use of nitrogen. The experiment was laidout in Randomized Block Design with ten treatments. Results of the investigation revealed that significantly the highest quality parameters of rice like head rice recovery, volume expansion ratio, iron and zinc content were recorded by the application of 50 per cent nitrogen though organics and 50 per cent nitrogen through in-organics and it was on par with 100 per cent RDN through organic source treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
