Fruit retention loads, fruit positions and seed yield

Studies were carried out during kharif 2023 -2024 to assess the influence of fruit load in okra cv. Arka Anamika on seed quality and yield. Data on fruit and seed characters was recorded. Significant differences in all the growth parameters except days to flower initiation were noticed due to fruit retention load. R1 (Retention of fruits borne on different nodes for seed purpose and harvesting remaining fruits for vegetable purpose) fruit retention load recorded significantly highest fruit length (10.01 cm), number of fruits/ plant (23.83 ) and number of seeds per fruit (52.58) respectively over R2 (Retaining all fruits) fruit retention load. Fruit positions differed significantly among themselves in days to flower initiation, fruit length, number of fruits/ plant, and number of seeds per fruit. Fruit position P1 (collection of seeds from fruits borne on 1-3 nodes) recorded significantly maximum fruit length (11.29 cm), number of fruits/ plant (23.83), number of seeds per fruit (58.72) and lowest days to flower initiation (40.71) over other fruit positions respectively while lowest fruit length (8.44 cm) and number of seeds per fruit ( 41.68) was recorded in fruit position P2 (collection of seeds from fruits borne on above 8th node) and highest ( 42.30 ) days to flower initiation was also recorded in fruit position, P3 respectively. Green fruit yield exhibited significant difference on fruit positions only because, in R2 (retaining all fruits), green fruits were not harvested for vegetable purpose. Among the fruit positions, significantly highest green fruit yield (3624.00 Kg/ha) was recorded in P1 (collection of seeds from fruits borne on 1-3 nodes) fruit position while was recorded respectively. Significant difference in seed yield was found due to fruit retention loads. The fruit retention load, R1 (Retention of fruits borne on different nodes for seed purpose and harvesting remaining fruits for vegetable purpose) recorded significantly highest seed yield respectively. Seed yield differed significantly due to fruit position. The seed quality assessed by standard germination %, test weight, root length, shoot length, seedling dry weight, seed vigour index-I and II exerted significant differences due to fruit positions and fruit retention loads values. The fruit retention load R1 recorded significantly higher values for standard germination % (79.11 %), test weight (62.84 g), root length (13.90 cm), shoot length (19.22 cm), seedling dry weight (0.210 g), seed vigour index –I (2649.29), seed vigour index –II (16.80) over R2 respectively. Among the fruit positions, the fruit position, P1 (collection of seeds borne on 1-3 nodes) recorded significantly maximum germination % (83.76%) test weight (72.21 g), root length (13.90 cm), shoot length (20.18 cm), seedling dry weight (0.264 g), seed vigour index-I (2936.72), seed vigour index –II (22.18) respectively while, lowest values for germination % (67.24 %) test weight (46.73 g), root length (12.04 cm), shoot length (17.43 cm), seedling dry weight ( 0.169 g), seed vigour index-I (2089.29 ) seed vigour index –II (11.37 ) were recorded in P3 (From fruits borne on above 8th node) position of the fruit respectively.
