Abstract: The Design of worldwide rice production is linked to the development of hybrid rice. Total rice growing land will be reduced due to the production of hybrid rice which has helped to feed people worldwide. The present study was initiated to select the few hybrid seeds of rice as compared with Nationally selected 6 number of check hybrid seeds or control. The field experiment was conducted at Nuziveedu Seeds Limited, Regional Research Station, Barrackpore, 24 Parganas North (22º 7’48” and 88º 30’ 0’’ E), Kolkata-700121, West Bengal, India, during the Rabi season in the year of 2021-2022. Altogether, sixty-six (66) treatments were carried out in a Randomised Complete Block Design (RCBD) with four replications in the Regional Research Station. The obtained data exhibited the higher yielding capacity only 12 No. of hybrids and the occurrence of a 5% extra yield deviation from the control hybrids' yielding capacity. The tallest height (cm) of variety (T58= NPHK-2), maximum length (cm) of panicle (T40=TCH-54), highest Days of Flowering (50%) (T57=NPHK-14 and T27=NPHK-3), highest of Ear Bearing Tiller number (T13=NPHK-28), highest Grain panicle-1 number (T51=TCH-44)), maximum Chaffs panicle-1 number (T19=TCH-100), highest Plant yield (gm) (T54=TCH-94), maximum 1000 Grain weight (gm) (T49=TCH-97), maximum Plot yield (Kg) (T49=TCH-97) and maximum Yield production tons ha-1 (T49=TCH-97) were observed all morphological parameters in compares with control treatments. Out of the 60 hybrids, only 12 numbers promising hybrids T49= TCH-97, T50= NPHK-17, T51= TCH-44, T52= NPHK-18, T53=TCH-38, T54=TCH-94, T55=TCH-106, T56=TCH-42, T57=NPHK-14, T58= NPHK-2, T59= NPHK-8, and T60=TCH-86 in yielding capacity have been selected for large scale seed production. Henceforth, the above-mentioned hybrid seeds are available for undertaking large-scale farming by farmers.

Abstract: Profitable fish farming, as one of the fastest growing sectors of food production, requires the knowledge of resource use efficiency, especially by farmers who run hatchery. This study therefore examined the economic viability of Clarias gariepinus fingerlings production in Ibadan, Oyo State, Nigeria. The study used primary data sourced from 31 purposively selected hatchery farmers. Data were analysed using descriptive statistics, profitability ratios, 3-points likert scale, and Pearson chi-square correlation test. Findings show that Clarias spp. was mostly cultured alone (38.7%) for over 6 months (77.4%), broodstocks were mainly sourced from private farms (61.3%), and fingerlings were harvested more than thrice per year (71.0%). The average fish seed produced per cycle is 15,451.6. The costs and returns per cycle showed a higher total variable cost (₦237,919.90) than the total fixed cost (₦104,705) incurred, of which fish feed had the highest proportion (22.6%). The profitability results show a positive benefit-cost ratio (1.54), expense structure ratio (0.44), and return on investment (0.54), showing that production of catfish fingerlings is economically viable. Furthermore, there exist significant relationships between cost of fish feed (x2=16.336, p<0.01), poor fish breed (x2=9.772, p<0.05), obsolete technologies (x2=17.718, p<0.01), and transportation cost (x2=16.118, p<0.01) with production capacity of catfish fingerlings. Thus, challenges faced by fingerling-producing farmers significantly influence the production capacity of catfish fingerlings in Ibadan. Therefore, measures should be put in place to ensure affordable loans, prompt extension services, availability of fish feed, and supply of quality broodstock to hatchery fish farmers in Ibadan, Oyo state, Nigeria.
