Different concentrations of compost applied as organic fertilizer can modify productive, quality, and chemical parameters in several fruit tree species. The objective of this study was to determine the effect of increasing applications of compost on physiological, productive, and quality parameters in calafate fruit during the seasons of 2018–2019 and 2019–2020. The study was conducted on a commercial calafate orchard using a randomized complete block design with four treatments (CK: no compost application, T1: 5 Ton ha−1, T2: 10 Ton ha−1, and T3: 15 Ton ha−1), each with four repetitions. The results did not show statistical significance for stomatal conductance (Gs), quantum yield of PSII, or photosynthetic active radiation (PAR) within treatments. As for fruit yield, a statistical difference was found between the control treatment and T1, which were lower than T2 and T3 in both seasons. The trees reached a higher leaf area index with T2 in both seasons. The highest antioxidant capacity was obtained with T3 and T2 for the first and second season, respectively. Polyphenols and total anthocyanin production showed statistical significance, with a higher content at the second season with T2. It is concluded that the dose under which yield, quality, and nutraceutical content of calafate fruit are optimized is the one used in T2, 10 Ton ha−1.

The study was carried out to find out the effect of zinc (Zn) and boron (B) on growth and yield of okra (BARI Dherosh 1). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The treatments of the experiment were, T0 (without Zn or B), T1 (20 kg Zn ha-1), T2 (30 kg Zn ha-1), T3 (10 kg B ha-1), T4 (20 kg B ha-1), T5 (20 kg Zn ha-1 + 10 kg B ha-1), T6 (20 kg Zn ha-1 + 20 kg B ha-1), T7 (30 kg Zn ha-1 + 10 kg B ha-1) and T8 (30 kg Zn ha-1 + 20 kg B ha-1) were undertaken to evaluate the best results of the study. The highest plant height was found in T8 (30 kg Zn ha-1 + 20 kg B ha-1) but the highest number of leaves plant-1 was recorded from T7 (30 kg Zn ha-1 + 10 kg B ha-1). On the other hand, the maximum leaf area index, SPAD value, mean fruit weight, fruit length, fruit diameter, fruit dry matter (%), number of fruits plant-1, fresh fruit weight plant-1 , fruit yield plot-1 and fruit yield ha-1 were found in T7 (30 kg Zn ha-1 + 10 kg B ha-1), while the control (T0) showed lowest performance for the respected parameters. It is strongly concluded that 30 kg Zn ha-1 with 10 kg B ha-1 combination may be helpful for okra cultivation in the field level to increase okra production.

A field trial was conducted at the Experimental Farm of the University of Benin, Benin City, Nigeria between May and July in both 2015 and 2016 to evaluate growth and yield responses of cucumber (Cucumis sativum L.) to different nitrogen levels of goat manure. The experiment was laid out in a randomized complete block design involving five treatments and replicated three times. The treatments were cured goat manure applied at levels of 0, 100, 200, 300 and 400 kg N ha-1. Growth parameters were collected on vine length (cm), vine girth (cm), number of branches, number of leaves and leaf area index (LAI). Yield parameters assessed were fruit length (cm), fruit girth (cm), number of fruits per plant and fruit yield (t ha-1). Goat manure application significantly (P < 0.05) influenced growth parameters positively, which led to the enhancement of the fruit yield. Goat manure application levels of 200 (20.85 t ha-1), 300 (20.85 t ha-1) and 400 (26.21 t ha-1) kg N ha-1 had similar (P > 0.05) fruit yield, but significantly (P < 0.05) higher than those of 0 (12.34 t ha-1) and 10 (16.96 t ha-1) kg N ha-1. It thus recommended that goat manure at 20 kg N ha-1 is more appropriate for cucumber production in the humid ultisols environment.

ABSTRACT This study aimed to evaluate the use of wastewater from the cassava processing as organic fertilizer on pastures of Brachiaria brizantha cv. ‘Marandu’. The treatments were wastewater doses (0, 15, 30, 60 and 120 m3 ha-1), in a randomized block design with four replicates. The structural characteristics and morphological composition of the pastures were evaluated, from July 2013 to January 2014. The addition of wastewater promoted a positive linear increase in the three cuts for the canopy height, light interception and leaf area index. The maximum dry matter (DM) production was obtained with 120 m3 ha-1 of wastewater (2796 kg ha-1 of DM in the second cut). The mass of senescent material in the second and third cuts fitted to positive linear equation. The increase in wastewater doses promoted the reduction of undesirable plants. The recommended dose of residual water in pastures of ‘Marandu’ grass is 120 m3 ha-1, which promotes a higher mass of forage and lower of undesirable plants.
