“…Our results revealed that the positive and significant correlation between number of fruits plant -1 and 100 seeds weight (r 2 =0.919), agree with that of result by Kaya et al (2005), they observed positive and non significant correlation. The significant inverse correlation between moisture and starch (r 2 =0.901) obtained supports results of Casanas et al (2002) and Guchhait et al (2008). Above relationships indicate that improving number of leaves and leaf area as well as increasing number of fruit and chlorophyll contents could accompany improvement in energy value as well as quality of fruits.…”

To study the effect of foliar application of humic acid at 0.05%, zinc at 0.05% and boron at 0.02% on biochemical changes related to productivity of pungent pepper cv. Bullet (Capsicum annuum L.), a pot experiment in randomized block design with three replications was conducted in the net house of Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia-741252, West Bengal, India. In This experiment, we observed some physiological and biochemical characteristics of pungent pepper. Obtained results revealed that the highest value of height of plant, numbers of leaf plant-1 , leaf area, numbers of branch plant-1 , numbers of fruit plant-1 and fruit length were exhibited by foliar application of HA + Zn + B. The highest value of fruit diameter, weight of 20 fresh fruits, numbers of seed fruit-1 and weight of 100 seeds were exhibited by foliar application of Zn + B and HA + Zn + B, respectively. The total chlorophyll content significantly increased in HA + Zn + B followed by HA + B and Zn + B application. The highest value of reducing sugar, total sugar and starch content were obtained by application of HA + Zn + B. The highest content of protein, fat, energy and total phenol were exhibited by foliar application of Zn + B, Zn, HA + Zn + B and HA + Zn + B, respectively. The activity of polyphenol oxidase was significantly 'good performer' in HA + Zn + B followed by HA and HA + B application. There are significant and positive correlation of starch with some physiological characteristics such as leaf area, number of fruits plant-1 , fruit diameter and total chlorophyll. The correlation of energy value with carbohydrates, fat, protein, total chlorophyll and leaf area were positive and significant. Based on principle component analysis and considering average values of all variables, our results suggested that the good promising treatment in HA + Zn followed by Zn + B, HA + Zn + B and Zn alone application may bring about the proper value addition in quality as well as productivity of crop by enhancing the some physiological and biochemical characteristics in pungent pepper.

Corms of eighteen (18) genotypes comprising twelve (12) introduced and six (6) local genotypes were studied for their nutrient quality to provide information on their nutrient characteristics for a holistic development of the crop. The crop is known for its edible corms and leaves. Corms are boiled before eating and take a short time to cook as their carbohydrate structure is not complex. The leaves are eaten as vegetables. The crops were planted at Nobewam in the Ejisu-Juaben Municipality in the Ashanti Region of Ghana using the Randomized Complete Block Design (RCBD). The biochemical or nutritional analysis was done at Crop and Soil Sciences laboratory at Kwame Nkrumah University of Science and Technology (KNUST). Data were collected on the chemical and mineral compositions of the genotypes (corms). Variations were observed in both chemical and mineral characteristics. Carbohydrate content of the genotypes ranged from 62% to 76%; protein ranged from 13% to 25%; fibre ranged from 1% to 2%; calcium ranged from 0.29% to 0.72% and iron content ranged from 0.18 mg/100 g to 1.18 mg/100 g. Significant differences P<0.05 were observed in both chemical and mineral traits, indicating a higher degree of variability in the genotypes. Significant P<0.01 and positive correlations were observed between protein and energy levels; magnesium and iron; magnesium and calcium; and potassium and ash. The Principal Component Analysis (PCA) showed that the first component (PC1) accounted for 96% of variation. Some genotypes including; BL/SM/10, BL/SM/132, KA/019, SAO/020, BL/SM/151, BL/SM/80, BL/SM/116, BL/SM/16, and KA/035 possess desirable nutrient levels such as protein, fibre, carbohydrate, and iron which could be exploited for further development of taro in Ghana.

“…This result is of particular importance because, when taro is grown under upland conditions, cormels of suckers seldom reach a marketable size; and they may compete for assimilates with the marketable main corm. This finding may influence such decisions as to remove the competing suckers at later stages of crop growth [13].…”

“…Variation in mineral composition among the accessions of taro is probably due to differences in the genetic potential of each accession to obtain nutrients from the soil since different taro genotypes have different nutrient-use efficiencies [13,14]. As was found in the same study, regarding mineral content, high levels of variability in South East Asia and Oceania taro germplasm were also found with regards to chemical composition for minerals but also for lipids, proteins, amylose, glucose, fructose and saccharose [13,15]. Availability of N, P, K and S fertilizers increase yield as well as nutritional quality of root and tuber crops [16].…”

Taro (Colocasia esculenta (L.) Schott) is a staple crop of many of the South Pacific nations with an ever increasing export demand. In recent years, yields of taro have increased dramatically through breeding and selection. However, selections of improved lines are often entirely based on final yield. There are many physiological pathways by which increased potential yield may be achieved. Factors such as the accumulation of dry matter and nutrient use efficiency, merit investigation. Two improved (blight resistant) taro cultivars were planted and harvested for biomass measurements on 2 a monthly basis for a total of eight months (30-240 days after planting) through destructive sampling. At each harvest, plants were separated into various plant parts and their dry matter accumulation and nutrient content were determined. Comparatively, cultivar Samoa 2 showed significantly higher uptake of N (25%), P (37.5%), K (33%), Mg (36.4%), Mn (22.7%) and Zn (48.3%) than cultivar Samoa 1. Even though maximum levels of total plant uptake of nutrients by the two cultivars did not differ between the cultivars, cultivar Samoa 1 plants absorbed 17% less N, 26% less P and 20% less K than those of cultivar Samoa 2 with the uptake uniformly distributed over the entire life cycle of the crop. Although cultivar Samoa 2 resulted in higher total plant (19.6%) and corm dry matter (10.4%) productions, cultivar Samoa 1 had a higher nutrient use efficiency, (kg of edible dry matter produced per kg of nutrient taken up), for N, P, K, Mg, Mn and Cu over cultivar Samoa 2. However, for Ca, Fe and Zn. Cultivar Samoa 2 had a higher nutrient use efficiency over cultivar Samoa 1. Based on nutrient use efficiency of the cultivars, Samoa 1 is recommended for marginal to rich soils while Samoa 2 for good to rich soils.
