    Effect of Fruit Position and Fruit Retention Load on Seed Yield and Quality and Seed Invigouration Treatments on Seed Quality in Okra [Abelmoschus esculentus (L.) Moench]
    (UAS Dharwad, 2013) Basavaraj S. Lakkundi; A. S. Channaveerswami
    Studies on effect of fruit position and fruit retention load on seed yield and quality and seed invigouration treatments on seed quality in okra were made at Main Agricultural Research Station, Dharwad during 2011 and 2012 kharif seasons. Results of the experiment involving two fruit retention loads and seven fruit positions revealed that retention of fruits bourne on 1-8 nodes for the seed purpose and harvesting remaining fruits for vegetable purpose recorded significantly higher fruit length (27.54 cm), number of seeds per fruit (60.16), seed yield (659 kg/ha), economic yield (146350 Rs./ha), benefit :cost ratio (2.44) and seed quality parameters viz., normal seedling percentage (84.67%), seedling vigour index-I (3030) and lower hard seed percentage (5.37%) dead seed percentage (9.96%). Results of the experiment involving seven foliar insecticides sprays indicated that lamda cyhalothrin 30 g a.i/ha recorded significantly lower per cent fruit damage per plant (18.44), per cent seed damage per fruit (10.03), higher seed yield per ha (1548 kg), germination (85.46%) and seedling vigour index-I (3100). Results of the experiment involving hydropriming revealed that soaking the seeds for twelve hours and drying back to original moisture content recorded significnalty higher germination (79.75%), seedling vigour index-I (2731) and field emergence (77.93%). Results of the experiment involving osmopriming indicated that osmopriming of seeds with PEG 1.00 Mpa and drying back to original moisture content recorded significanlty higher germination (84.75%), seedling vigour index-I (3048) and field emergence (81.30%). Results of the experiment involving chemopriming revealed that chemopriming of seeds with KI @ 1.0% and drying back to original moisture content recorded significantly higher germination (83.25%), seedling vigour index (2944) and field emergence (79.50%).
