This research evaluated the growth, yield and quality of gypsophila New Amore® variety grown in gutters filled with substrate in a system with leaching recirculation in southern Brazil. The treatments were the result of the combination of four substrates [carbonized rice husk (CRH100%), raw rice husk (RRH100%), CRH + organic commercial substrate S10 (Beifort®) (15%) and RRH+S10 (15%)] with two pruning times (early and late). The substrates did not affect the dry matter partitioning between the flowers and vegetative organs or the balance between the shoot and root growth. However, RRH100% reduced the shoot growth, flower stem yield and quality. The CRH100% and RRH+S10 substrates can be indicated for gypsophila cultivation once, in a general way, they presented promising results. The late pruning increased the gypsophila growth and yield and benefited the quality of the stems. The gypsophila plants adapted well to the employed crop system.

Tuberose (Polianthes tuberosa L.) is a perennial summer flower grown by smallholders in Kenya for export. However, its production and export volumes have declined drastically due to nematodes infestation. This study evaluated the effect of Cleome gynandra accessions on nematode management on tuberose. Experiment was conducted at the Horticulture Research Field, Egerton University, Kenya using a randomized complete block design with four replications. The treatments were: five accessions of C. gynandra namely ‘Simlaw’, ‘Egerton’, ‘Taastrup’, ‘PS’ and ‘IP8’, applied at 6 kg/m2 and compared with Brassica napus, solarization and untreated control. Data was collected on growth and yield parameters, nematode infestation and quality of tuberose. Data collected was subjected to analysis of variance at p≤0.05 and means separated using Tukey’s test. Biofumigation with Cleome gynandra accessions helped to reduce nematode population by 34%, gall numbers by 83% and galling index by be 96% when compared with the control. Use of biofumigation helped to improve plant height and leaf number of tuberose by 16% and 87%, respectively, when compared with the control. Use of biofumigation helped to improve spike length by 32%, marketable spikes by 80%, and flower yield by 90% and reduced nonmarketable spikes by 95% when compared with the control. Based on the above results, use of Cleome gynandra accessions and other biofumigants such as rape seed can be used to manage nematodes and improve growth, yield and quality of tuberose.

The effect of organic mulches and mycorrhizal substrate on growth, yield and quality of Gold Milenium apples on M.9 rootstock. Can. J. Plant Sci. 94: 281–291. A 3-yr study was conducted to evaluate the effects of organic mulches and mycorrhizal substrate on growth and yield of apple cv. Gold Milenium grown on M.9 rootstock. Straw (rye), pine bark, conifer tree sawdust, compost (plant debris), cow manure, peat moss substrate (commercial), and mycorrhiza substrate (Mykoflor®, containing mycorrhizal fungi: Glomus intraradices, G. mosseae, G. etunicatum) were applied in spring of each year. All the applied treatments did not affect significantly the tree growth. Mulches did not have a positive effect on total soluble solids of the fruit and the number of fruits in different size categories. Only sawdust mulch significantly increased the number of fruit in size diameter class of 7.0–7.5 cm compared with the control. The use of mulches affected the concentration of macro- and microelements in leaves, particularly Cu, Fe, Mn and Zn. Mulches positively affected the pH and organic matter content of soil. The best results were observed with the use of the compost, cow manure and the mycorrhizal substrate, where the concentrations of P, K and Mg, most of microelements and soil organic matter were elevated.

Crop bio-life is used as a foliar spray to enhance the symbiotic effect between roots and soil micro-organisms enabling the plant to better assimilate nutrients essential for growth. The aim of the study was to assess the effect of crop bio-life on growth, yield and quality of wild okra. The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications. The experiment consisted of four treatments. The treatments were different crop bio-life concentrations of 0, 25, 50 and 75 ppm.  The highest plant height (103.5 cm) was obtained in plants treated with 25 ppm crop bio-life and the lowest plant height (91.2 cm) was in plants treated with 75 ppm crop bio-life. Plants with the highest chlorophyll content (29.08 µmol per m2) were those treated with 50 ppm crop bio-life while the lowest (18.6 µmol per m2) was 0 ppm treatment.  The highest wild okra yield of 22.3 g leaf wet mass was obtained in plants treated with 25 ppm crop bio-life and the lowest yield (12.9 g) obtained from plants applied with 75 ppm crop bio-life. From the results of this study, it was observed that the plants treated with 25 ppm crop bio-life grew better and had a higher yield, therefore, it is the treatment recommended to farmers.

There is an immense need to replace chemical fertilizers with biofertilizers to address the soil, environment, and health issues. Endophytic bacteria act as biocontrol agents and promote plant growth and yield. Present study was designed to evaluate the microbial effect of endophytic bacteria on growth, fruit yield and quality of phalsa (Grewia asiatica L.). Three years old healthy, disease and insect-pest free plants were selected for the study. Experiment was laid out in randomized complete block design with four treatments; control, two bacteria such as Burkholderia phytofirmans strain PsJN, Bacillus sp. strain MN54 and their combination (PsJN + MN54) with three replications. The treatments were applied after pruning (January) and flowering (March) as plants need nutrition for both vegetative and reproductive growth. Combined application of PsJN + MN54 resulted in greater vegetative and reproductive growths of plants i.e. number of shoots/plant (29.6), number of leaves/shoot (15.9), number of fruit clusters/shoot (14.0), number of fruits/cluster (14.1), fruit weight (13.7 g) and yield/plant (8.8 kg) than PsJN or MN54 alone and control. Fruit biochemical characteristic i.e. TSS (8.78 °Brix), TA (0.53%), ascorbic acid (44.44 mg 100 mL-1), total sugar (12.29%), reducing sugar (9.59%) and non-reducing sugar (4.92%) contents were also higher in plants treated with PsJN + MN54. All growth, yield and biochemical parameters correlated positively with each other except titratable acidity. Based on performance, the combined treatment (PsJN + MN54) can be applied at two stages, after pruning and at flowering, for better growth, yield and quality of phalsa crop.

Nano-fertilizers of essential plant nutrients, including micronutrients, have the potential to improve nutrient use efficiency and productivity of field crops in deficient soils. The present study reports the comparative influence of zinc oxide nanoparticles (ZnONPs) and bulk Zn salt (ZnSO4) on the growth, yield, and quality of fodder maize (Zea mays) (var. J-1006) cultivated under field conditions in the year 2019. Three levels (0, 20, and 40 mg L−1) of Zn fertilizers were used for seed priming and coating in triplicate following the randomized complete block design model. An increase in vegetative and yield parameters (number of plants, plant height, stover yield, plant biomass), acid detergent fiber (ADF%), and hemicellulose contents and shoot zinc (Zn) content on treatment of seeds with ZnONPs (20 mg L−1) concentration as compared to bulk ZnSO4 and control treatments was observed. The application of ZnONPs (40 mg L−1) significantly enhanced the total chlorophyll content, available soil nitrogen and phosphorus, neutral detergent fiber (NDF%), and cellulose contents and improved the total soil microbial counts and soil enzyme activities (dehydrogenase, acid and alkaline phosphatase enzyme activities), whereas a significant increase in available soil potassium and zinc contents was recorded under ZnONPs (20 mg L−1) treatments. These findings suggest an encouraging effect on the growth and yield attributing characteristics of fodder maize after ZnONPs seed coating at low concentration. Furthermore, ZnONPs seed coating can also be considered an effective tool for the delivery of Zn micronutrient to fodder maize crop.
