Declines in cabbage (Brassica oleracea var. capitata) crop quality may result from delaying harvest to allow for greater total yield. An accurate, reliable, rapid and inexpensive method to estimate yield before harvest not requiring direct weight measurements would assist cabbage growers and handlers in harvest scheduling. Results from 3 years of study during which a tool to predict cabbage yie...

Studies were conducted to assess the response of hot pepper cultivars for yield and quality in the local soil and climatic conditions of the US Virgin Islands. Seven cultivars namely `Ring of Fire’, `Compadre’, `Camino Real’, `Jalapeno M’, `Caribbean Red’, `Hungarian Yellow Hot Wax’, and `Aguila Real’ were tested in the field.Significant differences were observed in cultivars for marketable fru...

Despite the continuous breeding that has been conducted with asparagus (Asparagus officinalis L.) since the beginning of the last century, there is little information on parameters for predicting direct and indirect selection response. Yield traits for blanched asparagus production were studied along a two-year period in a half-sib family population planted in Zavalla, Argentina. Half-sib famil...

Root crops are an important staple food in the Pacific region. Yields are generally low and inorganic fertilizers are deemed an option to increase root crop production. The effects of inorganic N fertilizers on upland taro (Colocasia esculenta (L.) Schott) and sweet potato (Ipomoea batatas (L.) Lam.) were quantified with the aim to investigate relationships between inherent soil fertility, N up...

The northern root-knot nematode (Meloidogyne hapla) is a major pathogen of processing carrot in New York, significantly reducing marketable yield and profitability. Severely infected carrots are stubby, galled and forked and therefore unmarketable. In field microplot trials in 1996 and 1998, the incidence and severity of root-galling increased and the marketable yield of carrot decreased as the...

A study was carried out in mungbean Vigna radiata (L.) Wilczek) with eight ‘lines’ and four ‘testers’ crossed in a Line x Tester Genetic variability, heritability and genetic advance were estimated for marketable and its component yield traits in 48 lines of carrot (Daucus carota var. sativa L.). The study showed high ranges for total yield (3.15 -7.56 kg/plot), marketable yield (2.60 – 6.85 kg...

Eight plant densities (8.8, 9.5, 10.4, 11.4, 17.6, 19.1, 20.8, and 22.9 plants m ) in 2001–2002 and 12 plant densities (8.8, 9.5, 10.4, 11.4, 12.7, 14.3, 17.6, 19.1, 20.8, 22.9, 25.4, and 28.6 plants m ) in 2002–2003 were evaluated on growth and fruit yield of ‘Sweet Charlie’ strawberry (Fragaria ananassa Duch.) grown in a passively ventilated greenhouse. Plant densities were derived by varying...

Eighteen hybrid onion and 23 open-pollinated (OP) varieties were tested in southern New Mexico for plant characteristics, disease resistance, and bulb yield in order to determine if hybrid varieties outperformed OP varieties. Varieties were shortto intermediate-day in their bulbing response and were planted in the fall seasons of 1997 and 1998 and harvested the following May or June. Varieties ...

abstract in order to study the effects of irrigation regimes and plant spacing on bulb yield of two onion (allium cepa l.) genotypes, an experiment was conducted at kabootar abad research station of isfahan during two growing seasons (2005 and 2006). the experiment design was split-factorial with a randomized complete block arrangement with four replications. main plots included three irrigatio...
