Effects of phosphorous (P) level on performance, yield and nutritional value of Celosia argentea L. were evaluated with the aim of determining the P level that supports the best growth, yield and nutritional qualities of the crop. The levels of P were: normal (1.348 mg·kg-1 of P/pot, NP), medium (6.743 mg·kg-1 of P/pot, MP), high (13.48 mg·kg-1 of P/pot, HP) and no P application (control, CP). The crop growth rate (CGR) increased with  increase in phosphorus gradients (NP = 0.05 g/m2·d-1, MP = 0.09 g/m2·d-1 and HP = 0.12 g/m2·d-1). High and medium P rates increased the relative growth rate (RGR), HP had the highest RGR (0.05 g·g-1/day) followed by MP (0.04 g·g-1/day). Addition of P increased leaf area (LA) of C. argentea. Crude protein of the control was higher (5.56%) compared to the other P treatments (NP = 5.14, MP = 5.11 and HP = 5.03%). Phosphorus applications were beneficial for growth and enhancement of nutritional quality of C. argentea. NP and MP are recommended for growing this vegetablecrop.

Tomato is one of the most widely consumed fresh vegetables in the industrialized world and an important source of healthy constituents of the human diet. Despite the unique flavor characteristics of tomatoes, which make them extremely valuable in cooking, and their recognized beneficial role in the diet, the quality of tomato was traditionally only considered in connection to external appearances. As it happened with other highly requested crops, breeding programs of tomato focused their efforts on developing new varieties with higher yields and stress resistance, with better uniformity in fruit size, brighter color and prolonged shelf life. The downside of these strategies was that organoleptic features and nutritional value were often neglected, with a detrimental effect on commercial tomatoes. Over the last years, there has been an increase in consumers’ demand for tasty and healthy products. This aspect, paired with novel and multidisciplinary approaches to tomato research, allowed both sensory and nutritional qualities to be reconsidered as valuable parameters in breeding. In this review we describe the main chemical constituents of tomato, focusing on the flavor compounds (both volatile and non-volatile compounds) and secondary metabolites. Particular attention is paid to their beneficial effects on human health and their relevance to the overall quality of tomato.

Background: Among the pulse crops mungbean is one of the richest sources of protein. There is great loss in the yield of mungbean due to various reasons may be biotic or abiotic constraints. To overcome the yield loss various physiological activities are studied. Physiological activities of the plant are greatly influenced by the source manipulation, plant growth regulators and chemical in mungbean. In correspondence to this, an experiment was conducted to study the physiological parameters in greengram.Methods: A factorial randomized block design in two respective years, i.e. 2016 and 2017 to study the response of source manipulation (nipping, 25% defoliation and 50% defoliation), plant growth regulators (GA3 and NAA at 25 and 50mg/l respectively) and chemical (Thiourea 500 and 1000mg/l) on the physiological parameters like Crop Growth Rate (CGR), Relative Growth Rate (RGR), Net Assimilation Rate (NAR) and Leaf Area (LA) in greengram at 30, 45, 60 and 75 DAS/harvest at Regional Research Station, Anand Agricultural University, Anand. Result: From the obtained results it can be proposed that the physiological parameters like crop growth rate, relative growth rate and net assimilation rate increased with the increasing phase and decreased at harvesting stage. While leaf area increased significantly at each growth phase. The treatment of nipping M2 was noted significantly higher value for CGR i.e., 8.42, 16.17 and 11.48 g/cm2/day/10, for RGR i.e., 0.544, 2.967 and 1.290 g/day, for NAR i.e., 0.466, 2.959 and 1.484 mg/cm2/day and for LA i.e. 96.87, 218.94, 381.88 and 588.78 cm2. While the treatment S2 GA3 25 mg/l was noted significantly higher value for CGR i.e, 8.60, 16.67 and 11.69 g/cm2/day/10, for RGR i.e., 0.568, 2.938 and 1.202 g/day, for NAR i.e., 0.372, 3.043 and 1.529 mg/cm2/day and for LA i.e., 96.61, 224.75, 382.20 and 580.42 cm2 contributing to the higher seed yield under M2 nipping treatment i.e., (1719.7 kg/ha) and S2 treatment i.e., GA3 25 mg/l (1714.1 kg/ha). Thus, GAM-5 had a better source-sink partitioning efficiency.

The experiment was conducted at Coconut Research Station, Balaramapuram with an objective to assess the effect of seed invigouration with ZnSO4 and borax alone and along with Trichoderma viride on physiological parameters and nodulation of grain cowpea. Seed invigouration treatments had significant effect on physiological parameters as well as nodulation parameters in grain cowpea. Leaf area index and total chlorophyll content were found to be higher in seeds primed in ZnSO4 0.025 and 0.05 per cent for 4h at both 30 and 60 days after sowing (DAS). From 30 to 60 DAS, crop growth rate (CGR) and relative growth rate (RGR) were the highest in seeds pelleted with borax 50 mg kg-1 seed and from 60 DAS to harvest, seeds primed in ZnSO4 0.05 per cent for 4h registered the highest CGR and RGR. Total number of nodules and effective nodules per plant were found to be higher in seeds pelleted with borax 50 and 100 mg kg-1 seed. However, the nodule fresh and dry weight were the highest in seeds primed in ZnSO4 0.05 per cent for 4h. Hence it can be concluded that compared to seed pelleting with borax, seed priming with ZnSO4 was found better for nodulation as well as better expression of physiological parameters in grain cowpea.

Grazing strategies alter sward leaf area patterns of growth, affecting herbage accumulation and utilisation. The objective of this experiment was to evaluate the growth of marandu palisadegrass (Brachiaria brizantha cv. Marandu) swards subjected to strategies of intermittent stocking. The experiment was carried out in Piracicaba, São Paulo, Brazil, from October/2004 to September/2005. Swards were grazed at 95 and 100% canopy light interception (LI) to post-grazing heights of 10 and 15 cm, following a 2 × 2 factorial arrangement with four replications in a randomised complete block design. The response variables evaluated were: crop growth rate, relative growth rate, net assimilation rate, leaf area ratio and leaf weight ratio. In early and late spring, the highest crop growth rate was recorded for treatment 95/15 (11.2 and 10.1 g m-2 day-1, respectively), along with high values of net assimilation rate (4.4 and 6.9 g m-2 day-1, respectively), leaf area ratio (0.0095 and 0.0103 m-2 g-1, respectively) and leaf weight ratio (0.56 and 0.56 g g-1, respectively). To compensate reductions in net assimilation rate plants made some morphological and physiological adjustments increasing leaf area and leaf weight ratio. Relative growth rate and net assimilation rate were 26 and 50% higher, respectively, on swards grazed at 95% than at 100% LI. In early spring treatments 100/10 and 95/15 resulted in the highest relative growth rate (0.086 and 0.059 g m-2 day-1, respectively). Treatment 95/15 resulted in the most favourable pattern of growth (crop growth rate, relative growth rate, net assimilation rate), particularly during the transition period between winter and spring.

Effect of Nitrogen Fertilization on Yield and Quality of EndiveThe aim of the experiments carried out in 2007-2008 was to assess the effect of various nitrogen doses on the growth, yield and nutritional value of two endive cultivars Cigal and Excel. The effects of two types of fertilizers were compared: that of ammonium nitrate with that of the product Entec-26. On the basis of the results obtained, it was shown that endive cv. Excel produced a marketable yield that was on average by 35.5% higher than that of the cultivar Cigal. A significantly higher marketable yield of endive was obtained by fertilizing with a single dose of the fertilizer Entec-26, particularly at the rates of 90 and 135 kg N·ha-1, and also 180 kg N·ha-1. The experiments also revealed a significant effect of the fertilization method and nitrogen application rate on the biological value of the endive cultivars under evaluation. The cultivar Excel was characterized by a higher degree of nitrate accumulation, whereas the cultivar Cigal had a higher vitamin C content, dry weight, and chlorophyll content.

A trial was carried out to investigate the effect of limited water supply on leaf area duration (LAD), relative growth rate (RGR), crop growth rate (CGR), and above-ground biomass (AB) of spring maize. The results indicated that the LAD was significantly (p<0.05) increased by 10.6%, 15.4%, 16.9%, 19.3%, 13.4% and 17.0%,12.2%, 19.7%, 18.4%, 20.9% in MI1, MI3, MI4, MI5, CK than MI2 during both 12-leaf stage to heading and heading to silking. There was no significant difference (p>0.05) in RGR among all the treatments and check during 6-leaf to 12-leaf stage and silking to middle grain filling, but significant difference occurred during other measured stages. Also, significant difference was found in CGR among some treatments and check during all the measured growth stages. The maximum AB of maize was maintained in CK with 23.0 t ha-1, significantly improved by 16.2%, 16.2%, 22.3% and 41.1%, 35.3% respectively than in MI1, MI4, MI5 and MI2, MI3, and the minimum AB was recorded in MI2 with 16.3 t ha-1.

SUMMARYDifferences in the age at which okra pods were harvested (4, 7, 10 or 13 days after pod set) had no effect on vegetative growth or pod yield, but pods harvested more than seven days after pod set were of poorer quality. The reduction in pod quality arose mainly from an increase in crude fibre and a reduction in the moisture, crude protein and ash content of older pods.

Two pomegranate cultivars, Mollar de Elche, native to Spain, and Wonderful, the most widely cultivated pomegranate variety in the world, were studied in a commercial orchard in Sicily, and their phenological behavior was compared. During the development of the fruit, their dimensional growth was monitored, and after harvest, physicochemical and sensory analyses were carried out to highlight the differences between fruit of the two cultivars. Results showed that Mollar de Elche fruit require less time from flowering to fruit maturity, resulting in an earlier harvest, which was due also to a higher relative growth rate of the fruit’s diameters. On the other hand, physicochemical analyses confirmed that Wonderful is the variety that is most appealing for fresh produce consumers due to its intense coloring. However, Mollar de Elche showed economically desirable characteristics such as a good softness of the seed. Moreover, sensory analysis showed that fruit of the cv. Mollar de Elche was found to have a sweeter taste of both arils and juice.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh to investigate the effect of age of tiller seedlings, number of tiller seedlings hill-1 and application of urea super granules (USG) on some physiological attributes of transplant Aman rice cv. BRRI dhan52. The experiment consisted of two ages of tiller seedlings viz. 25- and 35-day old, three levels of tiller seedlings hill-1 viz.1, 3 and 5 seedlings hill-1 and three USG levels viz. 0, 1.8g and 2.7g USG per four hills in every alternate row. The experiment was laid out in a randomized complete block design with three replications. The effect of age of tiller seedlings, number of tiller seedlings hill-1 and USG application were significant on crop growth rate (CGR), relative growth rate (RGR), net assimilation rate (NAR) and leaf area index (LAI). The highest CGR and RGR were found by transplanting 35-day old tiller seedlings during the period at 15-30 and 60-75 DAT when 5 tiller seedlings hill-1 were transplanted. The highest NAR was observed at 60-75 DAT with transplanting 5 tiller seedlings hill-1 and the lowest one was recorded at 30-45 DAT. The highest LAI was found at 35-day old tiller seedlings during the period at 60 and 75 DAT when 5 tiller seedlings hill-1 were transplanted. CGR and RGR were found highest by applying 1.8 g USG at 45-60 and 60-75 DAT while NAR was the highest with application of 2.7g USG at 60-75 DAT and lowest one was found in control (0 g USG) at 45-60 and 60-75 DAT. The highest LAI was found by applying 1.8g USG at 15, 30, 45 and 60 DAT and the lowest one was found at 60 DAT in control and at 15, 30 and 45 DAT when 2.7g USG was applied. The highest LAI and CGR were found in older tiller seedlings (35- day old) by transplanting five tiller seedlings hill-1 fertilized with 1.8g USG whereas the highest RGR and NAR were obtained in younger tiller seedlings (25-day old) by transplanting single tiller seedling hill-1 fertilized with 1.8g USG per four hills of every alternate row.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19094 Progress.

O objetivo deste estudo foi avaliar o efeito de misturas de um substrato comercial e pó de fibra de coco (PFC) no crescimento e na qualidade de mudas de Inga laurina (Sw.) Willd. (Fabaceae). Tubetes de polietileno foram preenchidos com quatro misturas do substrato comercial HS Florestal® (HSF) e PFC nas proporções: T1 = 100% HSF; T2 = 80% HSF + 20% PFC; T3 = 60% HSF + 40% PFC e T4 = 40% HSF + 60% PFC. Os experimentos foram realizados de forma independente, em presença (experimento I) e ausência (experimento II) de adubação suplementar. Foram realizadas avaliações de crescimento e qualidade das mudas ao final dos experimentos, aos 81 dias (experimento I) e 110 dias (experimento II) após a repicagem. Concluiu-se que o uso da adubação suplementar não apresentou diferenças em crescimento e qualidade das mudas de I. laurina até o percentual de 60% de PFC misturado ao substrato comercial. Sem a adição de adubação suplementar, a mistura com 80% HSF + 20% PFC é indicada para a produção de mudas de I. laurina. Além disso, a ausência de adubação suplementar nitrogenada e a adição de PFC ao substrato estimularam a nodulação.Growth and quality of Inga laurina seedlings as a function of the substrate and additional fertilizationThe aim of this study was to evaluate the effect of mixtures of a commercial substrate and coconut coir dust (CCD) to grow Inga laurina (Sw.) Willd. (Fabaceae) seedlings. Polyethylene tubes were filled with four mixtures of a commercial substrate HS Florestal® (HSF) and CCD in the following proportions: T1 = 100% HSF, T2 = 80% HSF + 20% CCD, T3 = 60% HSF + 40% CCD and T4 = 40% HSF + 60% CCD. The experiments were conducted independently, with supplement fertilization (experiment I) and without (experiment II). Seedlings growth and quality were evaluated at the end of the experiments, 81 days (experiment I) and 110 days (experiment II) after transplanting. It was concluded that supplement fertilization presented no differences in the growth and quality of I. laurina seedlings until up to 60% of PFC mixed with commercial substrate. Without supplement fertilization the mix of 80% HSF + 20% PFC is indicate for production of I. laurina seedlings. Moreover, the lack of supplement nitrogen fertilization and addition of PFC to the commercial substrate stimulated nodulation.Index terms: Dickson quality index; Relative growth rate; Forest restoration
