Effect of Varieties on Growth and Yield of Yard Long Bean under Songhkla Conditions, Southern Thailand

Abstract

Yard long bean (<em>Vigna sesquipedalis</em> L. Fruw) is one of the most popular vegetables in many countries of Southeast Asia. Especially in Thailand, it has given high productivities for export in both fresh and frozen types. Yard long bean is considered as relatively low pod yield productivity and stability because it is quite sensitive to unfavorably environmental conditions, particularly for humid tropical regions with turmoil weather. The effect of varieties on growth and yield of yard long bean was conducted at Department of Plant Science, Faculty of Natural Resources, Prince of Songkla University, Hat Yai campus, Thailand to test for yield and other horticultural characteristics of seven varieties of yard long bean. All varieties of yard long bean were well grown under Songkhla’s conditions. Randomized complete block design (RCBD) was used with four replications. The experiment was taken from February to April, 2014. The results showed that the Mae Ping, Euro, Green Arrow, Kheow Dok, and Saifa varieties exhibited good growth and high yield. The Mae Ping variety gave the highest marketable yield of 12.25 t<sup>.</sup>ha<sup>-1</sup> not significantly different (p≤0.05) from the Euro, Green Arrow, Kheow Dok, and Saifa varieties which gave the marketable yield of 15.16, 14.13, 13.51, and 13.34 t<sup>.</sup>ha<sup>-1</sup>, respectively. The Negro and Taiwan varieties were the second high yielding varieties which gave the marketable yield of 11.90 and 11.92 t<sup>.</sup>ha<sup>-1</sup>, respectively. The Euro, Kheow Dok, Saifa, and Taiwan were interesting varieties because they had pod length longer than 60 cm to meet the needs of the consumers in Songkhla province and around this area. It is concluded that the Mae Ping, Euro, Green Arrow, Kheow Dok, and Saifa varieties were the most suitable for growing under Songkhla conditions, southern Thailand due to its high growth and yield.

Silvicultural, hydro-orological and economic aspects of a combination of vegetative (Falcataria moluccana-Vigna cylindrica) and terrace systems in soils of different slopes

“…Yard long bean (Vigna sesquipedalis L. Fruw) is one of the most popular vegetables in many countries of Southeast Asia, but this species has relatively low yield productivity (Nooprom and Santipracha 2015). The production, harvested area, and productivity of Vigna cylindrica (long beans) in Indonesia in 2017 was 381,185 ton; 56,111 hectare, and 6.79 ton hectare -1 , respectively (Ministry of Agriculture Republic of Indonesia 2018).…”

Phenotypic diversity and evaluation of fresh pods of cowpea landraces from Southern Europe

“…These findings indicate that green cowpea pods with an absence of pigmentation are preferred when consumed as vegetables in Southern Europe, as in many other parts of the world . Indeed, the green pod color with an absence of pigmentation has been found to be the most prevalent type in other cowpea collections worldwide, as well as in common bean …”

“…These findings indicate that green cowpea pods with an absence of pigmentation are preferred when consumed as vegetables in Southern Europe, as in many other parts of the world. 29 Indeed, the green pod color with an absence of pigmentation has been found to be the most prevalent type in other cowpea collections worldwide, 19,21 as well as in common bean. 30,31 Cowpea fresh pods were mostly characterized by a very small pod weight (1.41-5.89 g) and pod length (8.55-22.08 cm), medium diameter (0.68-0.76 mm) and medium number of locules (10-12) (see Supporting information, Table S2).…”

“…sesquipedalis. 18,19 Taking into account the lack of improved lines, the possibility of increasing incomes from cowpea cultivation and the growing consumer demands for vegetable cowpea in Europe, the present study aimed to: (i) determine diversity in fresh pod traits; (ii) define the most promising landraces regarding fresh pod yield; and (iii) identify significant correlations among fresh pod traits of a collection of cowpea landraces originating from Portugal, Spain and Greece.…”

Evaluation of Local and Exotic Hybrid Genotypes of Yardlong Bean (Vigna unguiculata) in Saline Prone Area of Bangladesh

“…with up to 10 subspecies distinguished, most of which are perennial wild types (Tantaswat et al, 2010). Due to its economic importance, agriculturalists aim to increase production to meet the high demand from consumers, particularly in Southeast Asian, Chinese, and Filipino cultures (Nooprom and Santipracha, 2015).…”
