Abstract
An Investigation was carried out with three experiments for studying the
influence of plant population and nutrient management on seed yield and quality of
baby corn hybrid at Water and Land Use Management Institute (WALMI) farm,
Dharwad, during Kharif 2010. Influence of sieve size grading on seed quality and
storage on specialty corn were studied at Seed Quality and Research Laboratory of
National Seed Project (crops), University of Agricultural Sciences, Dharwad.
Significantly higher seed yield (48.22 q ha-1) was recorded with 200:100:80 kg
NPK ha-1 compared to 150:75:37.50 kg NPK ha-1 (41.36 q ha-1). Significantly higher
seed yield (48.08 q ha-1) was recorded with spacing of 60 x 25 cm compared to
spacing of 60 x 10 cm (38.71 q ha-1). Among interaction application of
200:100:80 kg NPK per ha with spacing of 60 x 25 cm recorded significantly higher
seed yield (51.33 q ha-1).
Among four genotypes significantly higher seed recovery (95.38 %) and
germination (99.32 %) were recorded with the genotype PEHM-2. Significantly
higher seed recovery (95.48 %) was recorded in lower sieve size with Top: 10.50 mm
X Bottom 3.50 mm. whereas higher germination (99.34 %) was recorded with higher
sieve size Top: 10.50 mm X Bottom 6.00 mm.
The seeds of PEHM-2 genotype recorded significantly higher germination
(88.94 %) compared to the rest of the genotype studied. Among four treatments T3
(Thiram @ 2.5 g kg-1 seed + Malathion @ 2 g kg-1 seed) recorded significantly higher
germination (90.13 %) at the end of twelth month of storage period as compared to
the rest of the treatments. Higher seed germination was recorded with seeds stored in
polythene bag (87.58 %) as compared to cloth bag (85.81 %) at the end of twelve
months of storage period.
