Background: Yard-long bean is one of the exporting crops of Fiji, with approximately half a ton exported annually. Lack of information on the varietal performance under the field condition walls the ability of farmers to choose a suitable variety for higher production under different growing conditions. Therefore, this study aims to identify a higher-yielding variety of yard-long bean that performs to the maximum under the tropical climate of Fiji. Methods: Three varieties of yard-long bean were selected based on their availability and were planted under three different growing conditions. The data on the chlorophyll content, stem girth, plant height, pod number, pod length and pod weight were collected and analyzed. Result: The experiment results indicate that the JS15P variety of yard long bean had significantly the highest leaf chlorophyll content in Trial 1 and Trial 2; however, no significant differences were observed in Trial 3 among the three varieties. No significant differences were observed in the stem girth among the three varieties. As for the plant height, the JS15P variety had significantly the highest among the other two varieties. The results also indicated that the JS15P variety of yard-long bean had significantly the highest yield in all three trials; therefore, the JS15P variety of yard-long bean is highly recommended to farmers in Fiji or those cultivating crops under tropical climatic conditions.

Effect of laser priming on canola yield and its components under salt stressThe effect of laser priming at different irradiation times on canola yield and its components under saline conditions were investigated. The results showed that laser priming had a positive effect on yield and its components and caused yield increase under saline conditions. Increase in salt levels had a negative and significant effect on seed yield, number of seeds per pod, number of pod per plant, pod length and plant height. The results showed that 45-min laser priming had the strongest effect on yield and yield components and reduced significantly the adverse effects of salinity. By contrast, laser radiation applied for 60 and 75 min, resulted in a dramatic decrease in yield and its components. Correlation coefficients between the attributes showed that canola yield had a positive and significant correlation with plant height, number of seeds, pod per main branch and lateral branches, length of pod and number of lateral branches. Effects of laser and salinity were significant on lateral branch pod length but not on main branch pods.

Correlation Study with Path analysis was performed on 29 Lentil Genotypes to determine direct and indirect effect of some morphological as well as Biochemical parameters on Yield. Following traits were studied: Root Nodule number, Nodule weight, Primary Root Length, Secondary root numbers, Root Fresh and Dry weight, Plant Height, Pods per plant, Days to 50% Flowering, 100 seed weight, Leaf chlorophyll content, Seed Carbohydrate with Starch content, Seed Protein content and Yield. Considering both genetic Advance and GCV, it was observed that selection for the following characters viz. Plant Height, Pods per plant, Days to 50% flowering, 100 seed weight, Seed Protein content & Yield will be rewarding. Seed Yield per plant showed significantly Positive correlation with the following traits: 100 Seed weight, Pod number per plant, Plant height and seed starch. Negative association with yield was found for Days to 50% flowering. Path coefficient study revealed that there was a strong positive direct effect of 100 seed weight and Pod no. per plant along with Leaf Chlorophyll content on Yield. Hence, direct selection only for Pods number and 100 seed weight will be rewarding as these characters also gave higher heritability % along with high Genetic advance. Plant height gave strong negative direct effect on yield, but it gave a positive correlation due to high indirect effect in association with pod number. It may be due to short winter span of West Bengal which results into forced maturity of the crops. So short plants with higher pod numbers will be desirable for higher yield in short winter span condition.

Lead (Pb) is one of the contaminants found in polluted air, especially in the area with dense traffic. Herbaceous plants are potentially used to reduce the Pb content in the polluted air. This study was designed to evaluate the potential of several plants, such as Jatropha integerrima, Duranta erecta and Hibiscus rosa-sinensis, as Pb absorbents from polluted air based on Pb accumulation and chlorophyll levels. The lead content was measured using atomic absorption spectrophotometry (AAS), while the chlorophyll content was tested using spectrophotometers at wavelengths of 649 nm and 665 nm. Results showed that the three plant species had potential as Pb absorbents from the air. The highest lead content was found from J. integerrima at 1.293 mg/kg, followed by H. rosa-sinensis at 1.232 mg/kg and D. erecta at 0.840 mg/kg. On the other hand, the highest level of leaf chlorophyll content was H. rosa-sinensis at 16.116 mg/kg, followed by D. erecta L. at 12.594 mg/kg and J. integerrima Jacq. of 10.297 mg/kg. No correlation was found between the Pb level and chlorophyll content of the three plants. It can be concluded that the three herbaceous plants have potential as Pb absorbents in the polluted air.

The present research was carried out to evaluate response of Bell peppers (Capsicum annuum L.) to plant density and nitrogen fertilizer under field conditions. Plant density at four levels (20×50 cm, 30×50 cm, 20×100 cm and 30×100 cm) and nitrogen treatments at four levels (0, 50, 100 and 150 kg·N·ha-1) were applied. Plant height, lateral stem number, leaf chlorophyll content, yield, and were assessed at immature and mature stages. The results showed that vegetative growth characteristics (plant height, lateral stem number and leaf dry matter) and reproductive factors (fruit volume and fruit weight) decreased with increasing plant density, but total yield (kg·ha-1) increased with increasing plant density. The highest and lowest total yields were obtained by plant density 20×50 cm and 30×100 cm respectively. Nitrogen fertilizer was significantly affected on plant height, lateral stem number and leaf chlorophyll content. It was observed that fertilization with 150 kg·N·ha-1 resulted to the highest fruit volume and plant yield. There were significant differences between fruit volume and fruit weight by interaction between plant density and nitrogen treatments.

Foliar Fertilizer

Foliar application of fertilizers can guarantee nutrient availability to beans, leading to higher yield and seed quality. Different approaches including glycine have been used to improve mineral nutrient status of plants toward safer products and improved human health. However, limited research has been undertaken to understand the response of beans to amino Zn and Mg foliar fertilizer application in Ghana. This study was conducted to investigate the effect of zinc, magnesium, and combined zinc and magnesium foliar fertilizer application on two improved common bean (Phaseolus vulgaris L.) varieties locally referred to as Adoye and Nsroma in the forest (Fumesua) and forest-savannah transition (Akumadan) agro-ecological zones of Ghana during the 2018 and 2019 cropping seasons. The treatments were arranged in split-plot design with the two improved common bean varieties as the main plot, and foliar fertilizer options (zinc, 200 g/ha; magnesium, 224 g/ha; combined zinc and magnesium, 100 g/ha Zn and 112 g/ha Mg) and water spray (control) as the subplot treatments. The zinc and combined zinc and magnesium treatments had similar and significantly ( P ≤ 0.05 ) higher plant height of 37.1 cm and 38.7 cm compared to the control and magnesium treatments. The results also showed that chlorophyll content was approximately 15.6% higher in plants treated with zinc plus magnesium compared to the other treatments. Similarly, stomatal conductance was significantly ( P ≤ 0.05 ) increased by 35.6% with zinc plus magnesium treatment relative to the other treatments. The improved chlorophyll content and stomatal conductance in those treatments resulted in ∼55.3–80.6% increase in crop biomass and seed yield. Crop performance parameters such as plant height, canopy spread, and chlorophyll content were significantly higher ( P ≤ 0.05 ) at Akumadan, resulting in a greater seed yield of 1486.2 kg/ha compared to 1365.3 kg/ha at Fumesua. Combined application of zinc and magnesium appears to be a potential soil improvement strategy for common bean production in tropical soil environment of Ghana.

This study presents the results of the variety comparison trials conducted with the French bean variety candidate BU-16 on sandy soil, during two years at the Research Center of the University of Debrecen.The outstanding characteristics of this variety candidate are the early maturity, the showy pods (yellow, straight, cylindrical cross-section „pencil bean”) and the high yield potential.The experiments were conducted with a randomized design, with five varieties and four replications. The varieties (of which two are foreign and three are domestic) were as follows: BU-16 fj, Maxidor, Paridor, Hungold and Budai piaci. The individual plots were 2 m wide and 4 m long. The seeds were sown at a density of 30 germs per m2, with a row spacing of 50 cm.The following parameters were taken: time of flowering, time of green maturity, plant height, height of the lowest pod above ground level, number of pods per plant, distribution of the pods by the state of development (20 plants), usable pod length (1 kg of standard crop-yield), yield per hectare based on the number of plants per plot. The experiments were evaluated statistically with Excel and SPSS softwares.Results obtained with the variety candidate BU-16:– The time from the emergence to green maturity is 45 to 46 days, which is short as compared with the other cultivars studied.– Plant height is 38cm (two years average), which is among the highest ones, together with Paridor.– The pods are set high above the ground level similarly to Paridor, the height of the lowest pod is 19 cm.– The average number of pods per plant is 13 (two years average) similarly to Paridor and to Maxidor.– The distribution of pod size in 2007 is as follows: 68% of the pods of BU-16 is of the standars size, which is a good rate. The value of this trait for the other varieties is 60 to 63%, except for Paridor, the value of which is similar to that of BU-16.– The usable pod length (10 to 14 cm) is 63% in 2007 and 84% in 2006. Similar pod length rates were obtained for Maxidor, while the rate for Paridor is as high as 91%.– The total yield and the standard yield of BU-16 is among the highest ones.According to the results obtained and presented above, the variety candidate BU-16 is the earliest maturing among the varieties tested with high yield potential which, however, is not significantly different from that of the others. Significant differences can only be detected in plant height and the number of pods per plant. Considering the results, BU-16 is to be further tested.

The Relationship

The relationship between SPAD-501 meter readings (SPAD) and total chlorophyll content (TCHL) was evaluated for `Delicious' apple (Malus domestica Borkh.) leaves grown in various environments. Regression models were developed between SPAD and TCHL for each of six separate experiments and were evaluated for statistical coincidence. SPAD was linearly related in a positive manner to TCHL in five of the six experiments; however, models differed between experiments, particularly between field- and greenhouse-grown trees. Thus, the relationship between SPAD and TCHL must be determined for each experiment.

Soybean has economically stood out worldwide. In MATOPIBA region of Brazil (Maranhão, Tocantins, Paiuí e Bahia) it is the most economically important crop with participation in the country’s GDP growth. Due to this great growth economic and the incentive to the production of this oilseed, this study aimed to understand the behavior and physiological quality of soybean genotypes and to determine the productive potential of soybean seeds of different cultivars in the Cerrado of the State of Piauí. To this end, an experiment was carried out at Celeiro Farm, located in Serra do Quilombo, municipality of Monte Alegre do Piauí. Sowing followed the usual standards and was carried out on January 10, 2016. The experiment was set up in a randomized complete block design with four replicates. The treatments consisted of five cultivars of INTACTA RR2 PRO soybean, with different maturity groups: C1: MG 8.6, C2: MG 8.3, C3: MG 8.6.1, C4: MG 7.9 and C5: MG 8.5. The analyzed variables were: plant height, number of nodes, internode length, pod length, number of grains per pod, number of grains per plant, one thousand seed weight, productivity, first germination count, germination, seedling length, germination speed index and seedling dry mass. The results indicated that the best cultivars were: C5:TMG 2185 IPRO for plant height, internode length and pod length, and C4: BÔNUS IPRO for number of grains per pod, number of grains per plant, one thousand seed weight, and productivity. Considering the first count, germination, and germination speed index, the best cultivar was C5.

Climate warming is subjecting plants to heat stress, which can affect their physiological processes thereby impacting their growth, development, and productivity. Potato (Solanum tuberosum L.) is a staple food worldwide, but potato crops are very sensitive to heat stress. We have studied the effects of heat stress on the leaf chlorophyll content, plant growth, and tuber yield of 55 commercial potato cultivars in clonal tests under heat-stress conditions [HS; 35 °C (day), 28 °C (night)] and control (non-stress) conditions [CK; 22 °C (day), 18 °C (night)]. The potato cultivars varied in their response to heat stress. Overall, heat stress reduced leaf size, increased the SPAD index values for leaf chlorophyll by up to 65%, and increased plant height by 64%, but severely reduced (by 93%) the mass of the largest tuber. The HS:CK SPAD ratios positively correlated with the HS:CK plant height ratio, mass of the largest tuber under heat stress, and the HS:CK ratio for mass of the largest tuber. Potato cultivars displayed a correlated response to heat stress for their leaf chlorophyll content, plant height, and tuber mass. We have identified the most heat-tolerant and heat-susceptible cultivars for these traits. Under heat-stress conditions, potato cultivars tend not to show as much reduction in tuber mass if the plants have greater increases in leaf chlorophyll content and plant height.

The effect of regional diversity on 12 agro-morphological descriptors of Sesbania bispinosa (Jacq.) W. Wight was studied. The mean sum of square varied significantly for six of these traits viz., plant height, branch number/plant, pod number/plant, pod length, seed number/pod and seed width. Among the ten regions, plants grown from seeds of Tangail, Chuadanga and Sirajganj districts of Bangladesh performed better in terms of plant height, number of branches/plant, number of pods/plant, pod length, number of seeds/pod and seed width. In principal component analysis, first six principal components (PC1, PC2, PC3, PC4, PC5 and PC6) showed Eigen value >1 and accounted for 85.6% of the total variance. In cluster analysis based on the studied agro-morphological descriptors, the cluster 1 consists of three regions (Chuadanga, Tangail and Jhinaidah), cluster 2 of six regions (Khulna, Mymensingh, Rangpur, Sunamganj, Gaibandha and Faridpur) and cluster 3 of only one district (Sirajganj). Considering these multivariate analyses, three different morphotypes of S. bispinosa could be identified from different locations.
