Evaluation Of Okra Cultivars And Breeding Lines For Agronomic Traits In Umudike In Southeastern Nigeria

Six (6) genotypes comprising two (2) cultivars and four (4) breeding lines of Okra (Abelmoschus esculentus (L) Moench) were studied in a randomized complete block design with three (3) replicates to determine their performance under Umudike environmental conditions in 2002 and 2003 cropping seasons. With respect to fresh pod yield, all the genotypes performed very well in both years, although the breeding lines performed better than the two (2) varieties. Breeding lines LD88/1-8-16-2 and LD88/1-8-13-2-4 recorded fresh pod yields of 3.6 and 3.2 t/ha in 2002, 3.5 and 3.3 t/ha in 2003 respectively, which are well above the fresh pod yields recorded for Okra in the tropics. The early maturing Okra genotypes used in the present study with 3 to 4 months duration present a possibility of growing two crops of Okra (early and late croppings) in one year, unlike the indigenous photoperiod sensitive varieties with eight to nine months duration.

Evaluation of Tomato ( Lycopersicon lycopersicon ) Cultivars for yield and yield attributes in acid soil

This work which evaluated different Tomato Cultivars for yield and yield related parameters was carried out at the Research and Training Farm ofMichael Okpara University of Agriculture, Umudike using a randomized complete block design (RCBD) replicated three times. Ten treatments, namely DT 95/140A, DT 95/433, DT 95/257, DT 95/38, DT 95/237, DT 95/3B, DT 95/43, DT 95/146, DT 95/133B, and Local B obtained from NIHORTIbadan were studied. Data were collected on plant height, number of branches, dry matter yield, number of flowers, fruit circumference, number of fruits and total fruit weight. Results showed Local B had the highest yield while DT 95/237 had the least yield. Correlation analyses showed that number of fruits and fruit circumference were positively and significantly ( P.0.01 ) associated with total fruit yield. Their contributions to yield were also verysignificant ( P.0.01 )
