Beetroot (Beta vulgaris L.) is one of the widely and popularly used salad vegetable in the Kingdom of Eswatini: However, there is scarcity of information pertaining to its organic production. A field study laid out in a Randomised Complete Block Design (RCBD) was conducted at the Horticulture Farm, Faculty of Agriculture, Luyengo Campus, at the University of Eswatini to determine the effects of cattle manure on growth, yield, quality and shelf-life of beetroot. Five treatments were applied in this experiment, and included cattle manure applied at 20, 40, 60, and 80 t/ha and a control of inorganic fertilizer, NPK [2:3:2 (22)] applied at 100 kg/ha as basal dressing and limestone ammonium nitrate (LAN) (28) applied at 80 kg as a top dressing. The treatments were replicated four times. The results obtained showed that beetroot grown under the application rate of 80 t/ha exhibited higher values in plant height (32.5 cm), number of leaves (9), leaf area (206 cm2), root diameter (5.1 cm), root length (11.7 cm), root fresh mass/plant (10.8 g), root dry mass/plant (9.2 g), marketable yield/plant (9.2 g) and quality [(aroma (33.5%), flavour (34%), texture (35%)] of the edible part. Plants supplied with 20 t/ha of cattle manure and inorganic fertiliser (control) gave the lowest vegetative growth parameters, quality parameters and marketable yield.

Abstract The adoption of melon hybrids by the productive sector necessitates a prior evaluation of the productivity, quality and shelf life of their fruits. Due to the different environmental conditions under which the hybrids are evaluated, an accentuated genotype-environmental interaction is expected to become apparent and likewise play important role in manifestation of phenotypic traits. The objective of the present work was to evaluate melon hybrids in the state of Rio Grande do Norte. The adaptability and stability of the genetic values were estimated by the HMRPGV method (Harmonic Mean of the Relative Performance of Genetic Values) for the following traits: yield, and soluble solids (SS) content in the period between 2010 to 2015. In 2017, the more promising melon hybrids from previous trials were evaluated under commercial conditions to determine the fruit’s yield, quality and shelf life. The predominance of the complex part of the genotype-environmental interaction was verified for both yield and SS content. Hybrids HC-02 and HC-11 show promising traits when grown under the conditions of the Mossoró-Assu Agricultural Complex owing their high stability, adaptability, yield, and fruit quality. Hybrids HC-02, HC-11, and ‘Hy Mark’ are suitable as international exports due to their long shelf life.

Background: Grapes are mostly propagated by hardwood cutting. Most of the time, auxin (Indole Butyric Acid) is used in liquid form. There are some problems associated with using auxin in liquid form viz. cell sap may exude from cutting end on dipping in solution that may lead to contamination, every time auxin solution should be freshly prepared etc. In order to address these problems, auxin hormone is used in powder form by using Talcum powder. Methods: In the present investigation, rooting powders containing different concentration of auxin were tried for root induction behavior. Approximately 15-20 cm long and 1-1.5 cm thick hardwood cuttings of grapes were taken. Result: The results indicates that grape cuttings treated with Indole Butyric Acid @ 3000 ppm in powder form was found to be best for root induction behavior. However, in most of the cases observations were at par with Indole Butyric Acid @ 2000 ppm (powder form) and with treatment @ 2000 ppm in liquid form but if we consider other benefits like long shelf life, no contamination etc. It can be concluded the rooting hormone in powder form should be considered better alternative to liquid form for root induction.
