The objective of this study was to evaluate the production of seedlings of Physalis L. species under different-colored shade nets. Four shade nets individually stained white, blue, red and black, all with 50% shading, were used in this study, and an additional treatment (control) was used in which seedlings were grown in full sun. The study examined four species of Physalis, namely, P. peruviana, P. pubescens, P. minima and P. ixocarpa. The experiment followed a randomized block design with three blocks and 25 seeds per plot. The species were sown in styrofoam trays. Germination was monitored daily to calculate the Emergency Velocity Index (EVI) and stabilize the overall percentage of emergence. Height, stem diameter, number of leaves, leaf area index and dry mass of seedlings were assessed at 50 days after sowing. The study found that these species react differently to changes in the light spectrum. Seedlings of P. peruviana should be grown under a white or red shade net; of P. pubescens under a white or black shade net; of P. minima under a white, red or black shade net; and of P. ixocarpa under a white shade net. For all species, 50% shade should be used.

A field experiment was conducted during 2017/2018 to assess the effects of Argel (Solenostemmaargel, Del. Hayne) and Nitrogen fertilizer on the performance of two Sunflower Hybrid cultivars, with the objectives to exploit an easy, economic, and accessible organic fertilizer, the Argel in the phase of the continuous increasing prices of chemical fertilizers.. This experiment was laid out on spilt-split-plot experiment in Randomized Complete Block Design (RCBD) with four replications. Observations were taken on some agronomic traits (Plant height (m), Leaf area (LA), leaf Number (NL), Leaf Area Index (LAI) and Mean Seed Weight). The results revealed that the application of Argel and Nitrogen fertilizer have significantly increased the leaf Area (F= 7.22, P < 0.001), Plant Height (F=2.68, P < 0.2001), Leaf Number (F= 3.90, P < 0.0024), Leaf Area Index (F= 3.83, P < 0.0026) and Mean Seed Weight of both Serena and Opera cultivars respectively compared to the control. However, the different treatments of Argel and Nitrogen reflected variable degree of increase for the studied parameters. The study concludes that Argel is very promising, therefore a further study with different levels of Argel including other plant parameters is recommended.

Abstract This study aims to analyse the effect of three types of organic fertilizers on the vegetative growth several varieties of soybeans. This study used a factorial randomized block design with two treatment factors, namely organic fertilizers and varieties. The first factor is: organic fertilizer from 3 levels, namely: K1 (1.5 kg of compost), K2 (1.5 kg of goat manure), and K3 (1.5 kg of chicken manure). The second factor is: soybean plant varieties consist of 4 levels, namely: V1 (Dena 1), V2 (Devon 1), V3 (Anjasmoro) and V4 (Derap 1). The parameters observed were plant height, number of branches, number of leaves, amount of chlorophyll, leaf area, and flowering age. The results of our research is organic fertilizers have a significant effect and are able to increase the growth of soybean plants except for leaf area and flowering age. Types of varieties had a significant effect and were able to increase plant height, number of branches, leaf area, and flowering age, but had no significant effect on the parameters of the number of leaves and the amount of chlorophyll. Moreover, there isn't interaction effect between the two treatments for all parameters.

The productivity of soybean in Assosa Zone particularly in Assosa and Bambassi districts is very low due to poor soil fertility management practices that resulted in severe soil acidity and low N-fixing inoculants in the soil. Hence, this experiment was conducted during the main cropping season of 2019 and 2020 in Assosa and Bambassi districts to evaluate the effect of biofertilizers, organic fertilizers, inorganic NPSB fertilizers, and lime on nodulation, growth, and yield of soybean (Glycine max L. Merrill). Factorial combinations of two biofertilizer inoculants (without biofertilizer (B1) and SB12 plus MAR1495 biofertilizers at their recommended rates of 500 g·ha−1 (B2); two organic fertilizers: without fresh cattle manure (M1) and fresh cattle manure at 10 t·ha−1 (M2); two lime rates: without lime (L1) and lime at 5 t·ha−1 (L2); two inorganic NPSB fertilizers: NPSB at 9.5-23-3.5-0.05 (F1) and NPSB at 19-46-7-0.1 (F2) at their recommended rates for soybean) were laid out in a randomized complete block design with three replications. Effective nodules, leaf area index, and grain yield were collected and analyzed using SAS 9.1.3 software. Results of the experiment showed that effective nodules, leaf area index, grain yield, bulk density, pH, total nitrogen, available phosphorus, organic carbon, and cation exchange capacity were highly ( P < 0.01 ) affected by the interaction of bio-, organic, and inorganic fertilizers and lime at both locations and years. Across all treatments, the grain yield of soybean was increased in the second year, while it was lowest in the first year at both locations. Finally, the interaction of SB12 + MAR1495, 10 t·ha−1 fresh cattle manure, without lime, and NPSB at 19-46-7-0.1 increased the grain yield of soybean in both Assosa and Bambassi districts and should be adopted appropriately to enhance the productivity of soybean in the areas and similar agroecologies, while the interaction effect of SB12 + MAR1495, 10 t ha−1 FCM, 5 t·ha−1 lime, and NPSB at 19-46-7-0.1 improved soil physicochemical properties in both the districts and similar agroecologies.

The aim of this study was to assess the leaf area index (LAI) of tomato and cucumber using an AccuPAR-LP-80-ceptometer to find the influence of irrigation. LAI was also determined by destructive sampling for comparison. The research was conducted at the Liaoning Water Conservancy Institute, North China in 2016. A randomized block design was used to test the influence of four treatments corresponding to field water capacity. Full irrigation (W1.0), 15% (W0.85), 25% (W0.75) and 35% (W0.65) water deficit were applied using the drip system. Regression model was developed to estimate LAI in response to irrigation. The results show that there is no difference between the two methods. The highest LAI obtained for tomato and cucumber was 5.21 and 3.21 m2/m2, respectively, with W0.85 at 70-days after transplanting, which corresponds with destructive results. This result was found 11% higher and equal compared with W1.0 for tomato (4.62) and cucumber (3.21), respectively. For both crops, LAI was found significantly influenced at 50-days after transplanting. It also indicated that LAI significantly influenced (by 15%) deficit irrigation for both crops and methods that achieved the highest yield. The predicted LAI was obtained best-fitting with the observed values, which indicated that the AccuPAR-ceptometer is suitable to be used.

The aim of this study was to evaluate the Paspalum oteroi native grass and its adaptive responses to shading and foliar fertilization in two pasture systems in the Cerrado-Pantanal transition region. A completely randomized block design with factorial arrangement was adopted to this study: three types of fertilizers [no fertilization – control (C); Foliar fertilizer for pasture (FF) and Soil fertilizer + Foliar fertilizer (SF)] x two pasture systems (WS - with shading, wooded P. oteroi pasture; NS - no shading, exclusive P. oteroi pasture) with four repetitions. P. oteroi seedlings were transplanted in November 2015. Data collection was from May 2016 to September 2016, during dry season. There were differences (p<0.05) in the sward height variables (H), dry matter (DM), crude protein (CP) content, dry matter production (DMP) and shoot: root ratio (S:R). In the WS system increased of 8,61% of the CP content and fertilizer SF increased of 8.81% of the CP content. However, in the WS system was observed reduced DM, DMP and S:R and in the FF and SF fertilizers increased leaf area index (LAI), in the latter months of the application. Probably, P. oteroi grass developed adaptation strategies to deal with the environmental conditions to which it was submitted during this study, such as variations in its morphophysiological traits: low shoot / root ratio, height, chemical composition, leaf area index e light interception. In conclusion, P. oteroi showed adaptation to wooded pasture systems, during dry period, however, the use of fertilization depends on economic viability studies.
