Abstract This study was carried to examine the best provenance of seed source of Manglietia glauca at 4.5 years old. The study was conducted in Candiroto, Temanggung, Central Java. A Randomized Complete Block Design with three provenances consisting of 15 parent trees from Tasikmalaya, ten parent trees from Sumedang, and 75 parent trees from Sukabumi, West Java, were divided into ten replications. Each replication has 100 plots, and each plot consists of four plants with a planting distance is 4 m x 3m. The plant characteristics, including height and stem diameter, were measured at the age of 0.5, 1.5, 2.5, 3.5 and 4.5 years. Variant analysis and Duncan Multiple Range Test in each measurement stage were performed. The significant differences of plant height among provenances were found from 0.5 to 3.5 years old and were not significantly different afterward. The stem diameter differs significantly among the provenances at 1.5 years old only; afterward, they were not significantly different. The average plant height and stem diameter at 4.5 years old were between 864-917 cm and 12.34-12.48 cm, and they were not significantly different. Therefore, it is possible to choose any seed sources of the three provenances of manglid to be used for plantation.

An experiment was carried out using eight double cross F1s (DCF1s) as lines and two testers to obtain sixteen Line ×Tester hybrids for the evaluation of major growth and flowering traits thereby to understand the breeding potentiality of the parental lines. The performance of growth and flowering traits of all twenty-six genotypes were evaluated in a randomized complete block design (RCBD) with three replications. The analysis of variance (ANOVA) showed all the genotypes were significantly different for all agro-morphological traits under study. The estimated general combining ability (GCA) effects showed that parent 5(P5), were superior for plant height, stem diameter, number of leaves, leaf length, days to flowering and attitude of floral axis followed by parent 2(P2) for leaf length, leaf width, days to flowering and attitude of floral axis and parent7 (P7) for number of flower, flower diameter, bud length and attitude for floral axis. Likewise; tester 1 found to be best combiner with significant GCA effect for almost all growth and flowering traits (except number of leaves). The plant height, leaf width, number of flower and attitude of floral axis showed prevailing additive gene action while stem diameter, number of leaves, leaf length, days to flowering, flower diameter and bud length indicated predominance of dominance gene action. We can conclude that parent P5, parent P2 and parent P7 can be used as good mother lines and the tester 1, as good donor for the seed production. SAARC J. Agri., 17(1): 175-187 (2019)

Onion (Allium cepa L.) is one of the most important vegetables in family Alliaceae, which is cultivated worldwide. In onion, weeds are among one of the major concerns which cause its yield reduction. The present study was designed to assess the effectiveness of different methods for weed control in onion. In this study, five treatments were selected including control, black polythene mulch sheet, white polythene mulch sheet, Dual Gold spray @ 9.0 mL L-1 and Preact spray @ 7.5 mL L-1 to control weeds. The weedicides were applied as pre-emergence sprays before transplanting the seedlings. The experiment was laid out in Randomized Complete Block Design with three replications. From the results, it was concluded that there were significant differences among the studied weed control treatments. Among the five treatments, greater plant height (33.0 cm), number of leaves per plant (8), bulb diameter (4.7 cm) and bulb weight (73 g) were observed in the ridges covered with black mulch sheet. However, the minimum weed biomass (fresh and dry) was recorded in black mulch sheet and Preact pre-emergence weedicide spray (140 and 80 g in both). Thus, black polythene sheet as mulching material was found better option for weed management in onion fields.
