Participatory varietal selection (PVS) with farmers and Seed Companies was conducted at Maradi research station (07°05'E/13°48'N) and in farmer field to evaluate and select sorghum hybrid varieties for high yield and other important agronomic traits. The experimental design was a randomized complete block with three replications where flowering (days), plant height (cm) and yield (kg) were collected. The analysis of variance showed highly significance among treatments of all traits measured Environment and Genotype by Environment interactions also contributed significantly to the performance of yield components. The highest average grain yield was recorded from hybrids P9511A x ST9007-5-2-1 (4289 kg/ha), NE223A x 90SN1 (3666 kg/ha), NE223A x Sepon 82 (3533 kg/ha) and NE223A x P9405 (3519 kg/ha) across locations. Farmers’ preferences were the panicle size, good seed set, earliness, and seed color. Hence, in a variety selection farmer’s preferences focus more on prioritized yield-related trait. The best varieties ranked by traits of interest were P9511A x ST9007-5-2-1, NE223A x 90SN1, NE223A x P9405 and P9511A x SEPON 82 that performed well under their circumstances. The results showed that farmers’ preferred varieties match with researchers. Therefore, based on objectively measured traits, farmers’ preferences and the agro ecologies of the site, varieties NE223A x 90SN1 and P9511A x ST9007-5-2-1 were found promising for production.

Introduction: Goiter is the most common endocrine disease in the world. The objective of our study is to assess and compare the morbidity linked to the surgical management of goiters and thyroid tumors in the general surgery department of the Niamey National Hospital. Result: We collected data on a prospective basis on 112 cases having undergone a thyroidectomy between March 2019 and April 2020. The female sex is predominant with 96.4%, i.e. a sex ratio of 0.037. The average age is 41.2 years with extremes ranging from 22 to 72 years old. The average duration of evolution of goiter is 7.5 years with extremes ranging from 5 months to 20 years old. The first reason for consultation is anterior cervical swelling. TSH testing confirmed euthyroidism in 107 patients (95.5%). Therapeutically, loboisthmectomy is the most performed procedure with 43.7%. The postoperative hormonal assessment revealed 32% hypothyroidism at 6 months, with a significant difference for cases of total thyroidectomy. The occurrence of postoperative hypocalcemia was significantly greater after total and subtotal thyroidectomy. There is no significant difference in terms of recurrent complications. Conclusion: Thyroidectomies must be performed after adequate preparation and information to the patient on possible postoperative complications, hence the need for close medical monitoring immediately and remotely.
