Department of Olericulture, College of Horticulture, Vellanikkara, during
September to December 1995 and May to August 1996 to study the source
efficiency relations of different organic manures on quality, productivity and shelf
life of okra. The experiment comprised of sixteen treatments and were laid out in a
randomised block design.
Study revealed that plant height at first harvest was increased by poultry
manure at highest dose (100 kg N ha"), Relative Growth Rate was higher for
groundnut cake equivalent to 75 kg N ha-I and 100 kg N ha-I during 30-45 DAS
and during 45-60 DAS the maximum RGR was for FYM at 75 kg N ha-I. During
30-45 DAS poultry manure at 75 kg N ha-I recorded maximum Net Assimilation
Rate.
Yield per plot was increased with groundnut cake equivalent to 75 kg N
ha-I and yield per plant was maximum for poultry manure at 75 kg N ha".
Mucilage content of fruit was maximum for poultry manure at 100 kg N
ha". Starch content was maximum for vermicompost at 75 kg N ha", when
organoleptic test was conducted the maximum score was obtained for FY M
equivalent to 75 kg N ha-I.
Percentage of unmarketable fruits showed difference for different
treatments and percentage of unmarketable fruits was maximum for control on fifth
day of storage.
Seed yield per plant was maximum for groundnut cake equivalent to 7S
kg N ha-I and number of seeds were maximum for poultry manure equivalent to 7S
kg N ha-I, Germination percentage was maximum for poultry manure equivalent to
50 and 75 kg N ha-I,
Soil properties like organic carbon and total nitrogen and pH did not show
significant difference by the addition of organic fertilizers,
Jassid incidence increased by higher dose of groundnut cake and poultry
manure, Mosaic incidence increased by higher levels of nitrogen,
Maximum net return was obtained from plots receiving higher dose (100
kg N ha") of poultry manure,
