Description A field experiment was conducted during rabi 2008-09 on sandy loam
soils of S.V. Agricultural College wet land farm, Tirupati Campus Acharya N.G.
Ranga Agricultural University, Andhra Pradesh to study the “Response of baby
corn genotypes to organic manures”. The experiment was laid out in a split
plot design, replicated thrice and the treatments consisted of three genotypes viz.,
golden baby (G1), G-5406 (G2) and G-5414 (G3) allotted to main plots and seven
manurial sources viz., recommended dose of fertilizer (T1), farm yard manure
(T2), sheep manure (T3), poultry manure (T4), green leaf manure (T5), cake (T6)
and vermicompost (T7) assigned to the sub plots.
Growth parameters of baby corn viz., plant height, number of leaves, leaf
area index and dry matter production were superior with the genotype (G3) while
the growth parameters were least with the genotype golden baby (G1). Among
the manurial practice, recommended dose of fertilizer (T1) resulted in the highest
stature of growth parameters .This was followed by the application of poultry
manure (T4) and green leaf manure (T5) while the lowest crop growth stature was
noticed with the application of vermicompost (T7). With respect to interaction,
the growth parameters were superior with the genotype G-5414 coupled with
recommended dose of fertilizer (G3T1), while the lowest values of growth
parameters were recorded with the genotype golden baby coupled with
vermicompost (G1T7).
The genotype G-5414 (G3) produced enhanced level of yield attributes
viz., highest values of cob length and girth, number of cobs plant-1 and cob
weight. The lowest values of the yield attributes were associated with golden
baby (G1). In case of the manurial sources, recommended dose of fertilizer (T1)
resulted in the highest stature of yield attributes followed by the application of
poultry manure (T4) and green leaf manure(T5) while the lowest level of the yield
attributes were associated with vermicompost (T7). Among the interactions, the
highest values of yield attributes were recorded with the genotype G-5414
coupled with recommended dose of fertilizer (G3T1) while the genotype golden
baby coupled with vermicompost (G1T7) accounted for the inferior values of the
yield attributes.
The highest husked and dehusked cob yields and fodder yield were
recorded with the genotype G-5414 (G3) whereas golden baby (G1) resulted in
the lowest yield level. Recommended dose of fertilizer (T1) resulted in the
highest husked and dehusked cob yields as well as fodder yield, followed by
application of poultry manure (T4) and green leaf manure (T5) while application
of vermicompost (T7) produced the lowest yield of husked and dehusked cob and
fodder yields. The yield obtained with poultry manure (T4) green leaf manure
(T5) with genotype G-5414 was lesser by 12 and 19 per cent respectively over the
recommended dose of fertilizer. With regard to interaction, the highest husked
and dehusked cob yields and fodder yield were recorded with the genotype G-
5414 coupled with recommended dose of fertilizer (G3T1) while the lowest yields
were recorded with golden baby coupled with vermicompost (G1T7).
The highest quality of cobs (protein, starch, carbohydrates reducing, nonreducing
and total sugars) was obtained with the genotype G-5414 (G3) while the
genotype golden baby (G1) resulted in the lowest quality. Regarding the manurial
sources, application of recommended dose of fertilizer (T1) produced the highest
quality cobs. This was followed by application of poultry manure (T4) and green
leaf manure(T5) .The lowest quality of cobs was associated with the application
of vermicompost (T7). With regard to interaction, the best quality characters were
recorded with the genotypes G-5414 coupled with recommended dose of
fertilizer (G3T1) while the lowest quality characters were observed with the
genotype golden baby coupled with vermicompost (G1T7).
The genotype G-5414 (G3) resulted in the highest nutrient (nitrogen,
phosphorous and potassium) uptake where as the genotype golden baby (G1)
resulted in the lowest values of all these. Recommended dose of fertilizer (T1)
recorded the highest nitrogen uptake by the crop where as the lowest nitrogen
uptake was recorded with vermicompost (T7).Among the interactions, the highest
nitrogen uptake was recorded with the genotype G-5414 coupled with
recommended dose of fertilizer (G3T1) while the lowest nitrogen uptake was
recorded with golden baby coupled with vermicompost (G1T7). With respect to
phosphorus uptake, application of poultry manure (T4 ) resulted in the highest
phosphorus uptake by the crop and the lowest uptake was recorded with neem
cake (T6).
Among the treatment combinations, the highest phosphorus uptake was
recorded by the genotype G-5414 coupled with poultry manure (G3T4) while the
genotype golden baby coupled with the application of neem cake (G1T6) resulted
in the lowest phosphorus uptake. The highest potassium uptake was noticed with
the application of vermicompost (T7) while the lowest amount was recorded with
the application of neem cake (T6).In case of potassium, the highest uptake was
recorded with the genotype G-5414 coupled with vermicompost (G3T7) while the
lowest uptake was recorded with the genotype golden baby coupled with neem
cake (G1T6).
The highest post harvest soil nutrient status (nitrogen, phosphorus and
potassium) was observed with the genotype golden baby (G1) while the genotype
G-5414 (G3) resulted in the lowest soil nutrient status. In case of the sources, the
highest post harvest soil available nitrogen and potassium were recorded with
application of vermicompost (T7) while the highest phosphorus content was
recorded with application of poultry manure (T4). The lowest soil available
nitrogen was recorded with recommended dose of fertilizer (T1) while the lowest
phosphorus and potassium contents were recorded with green leaf manure (T5).
With regard to interaction, the highest post-harvest soil available nitrogen and
phosphorus status was recorded with the genotype golden baby coupled with
vermicompost (G1 T7) while poultry manure (G1T4) accounted for the highest
phosphorus content with the same genotype. The lowest post harvest soil nutrient
status was recorded with the genotype G-5414 coupled with green leaf manure
(G3T5) in case of phosphorus and potassium while the same genotype along with
the recommended dose of fertilizer (G3T1) accounted for the lowest amount of
nitrogen.
The highest gross returns, net returns and benefit cost ratio were realized
with G-5414 compared to other genotypes while the lowest economic returns
were observed with golden baby (G1). Application of recommended dose of
fertilizer resulted in the maximum values of gross and net returns and benefit
cost ratio while the lowest values were recorded with application of
vermicompost (T7). The genotype G-5414 coupled with recommended dose of
fertilizer (G3T1) recorded the highest gross returns, net returns and benefit cost
ratio while the genotype golden baby coupled with application of vermicompost
(G1T7) resulted in the lowest economic returns.
The experimental results revealed that the performance of the genotype
G-5414 under recommended dose of fertilizer was found to be superior over the
rest of the treatment combinations. Since the present study pertains to response
of baby corn genotypes to organic manures, the next best alternative is to grow
the G-5414 genotype with the application of poultry manure (T4) or green leaf
manure(T5) for obtaining a better yield with good quality of baby corn.
