Abstract
An experiment was conducted on medium black calcareous soil at Junagadh
(Gujarat) to evaluate FYM, biofertilizers and botanicals for organic cultivation of
coriander (var. Gujarat coriander 2). Nine treatments comprising of Control (T1),
FYM @ 5 t/ha (T2), FYM @ 5 t/ha + Azotobacter (T3), FYM @ 5 t/ha + Azotobacter
+ PSB (T4), FYM @ 5 t/ha + Azotobacter + PSB + KSB (T5), FYM @ 5 t/ha +
Azotobacter + PSB + KSB + SOB (T6), FYM @ 5 t/ha + Azotobacter + PSB + KSB +
SOB + seaweed extract as foliar spray @ 3.5% at 30 and 60 DAS (T7), FYM @ 5 t/ha
+ Azotobacter + PSB + KSB + SOB + seaweed extract as foliar spray @ 3.5% at 30
and 60 DAS + banana pseudostem sap as foliar spray @ 1% at 30 and 60 DAS (T8)
and FYM @ 5 t/ha + Azotobacter + PSB + KSB + SOB + seaweed extract as foliar
spray @ 3.5% at 30 and 60 DAS + banana pseudostem sap as foliar spray @ 1% at
30 and 60 DAS + cow urine as foliar spray @ 5% at 30 and 60 DAS (T9).
Biofertilizers @ 1 lit/ha were applied as a drenching in all plots except control at a
time of sowing. Experiment was layed out in randomized block design with three
replications.
The results revealed that the growth parameters, yield attributes and yield,
quality parameters, content and uptake of nutrients, soil available nutrients and soil
properties were significantly influenced by the various organic treatments.
The experiment results revealed that the application of FYM @ 5 t/ha +
Azotobacter + PSB + KSB + SOB + seaweed extract as foliar spray @ 3.5% at 30 and
60 DAS + banana pseudostem sap as foliar spray @ 1% at 30 and 60 DAS + cow
urine as foliar spray @ 5% at 30 and 60 DAS (T9) was found superior in respect of
growth parameters, yield attributes and quality parameters along with higher seed
yield (1379, 1377 and 1378 kg/ha), stover yield (1585, 1581 and 1583 kg/ha) in 2018,
2019 and pooled results respectively, N, P, K, S and Mn content in seed, N, P, K, S,
Mn, Zn and Cu content in stover, N, P, K, S, Fe, Mn, Zn and Cu uptake by seed and
stover and total uptake by the crop, available N, P2O5, K2O, S, Fe and Mn, physical
and biological properties of soil. The highest contribution of organic sources in seed
yield of coriander was observed in FYM to the tune of 13.1 % followed by seaweed
extract (4 %).

ABSTRACT
Abstract
II
Application of FYM @ 5 t/ha + Azotobacter + PSB + KSB + SOB + seaweed
extract as foliar spray @ 3.5% at 30 and 60 DAS + banana pseudostem sap as foliar
spray @ 1% at 30 and 60 DAS (T8) enhanced the Fe, Zn and Cu content in seed, Fe
content in stover, available Zn and Cu content in soil and organic carbon content in
soil.
It is concluded that higher production of coriander under organic farming can
be secured by application of FYM @ 5 t/ha + Azotobacter + PSB + KSB + SOB +
seaweed extract as foliar spray @ 3.5% at 30 and 60 DAS + banana pseudostem sap
as foliar spray @ 1% at 30 and 60 DAS + cow urine as foliar spray @ 5% at 30 and
60 DAS (T9), which also maintain physico-chemical and biological properties of
calcareous soil under South Saurashtra Agro-climatic conditions.
