Five Trichoderma species/strains, Trichoderma virens IMI-392430, T. pseudokoningii IMI-392431, T. harzianum IMI-392432, T. harzianum IMI-392433 and T. harzianum IMI-392434 were tested against anthracnose and fruit rot of chilli. Effect of Trichoderma species in suppressing anthracnose and fruit rot as well as the growth and yield of chilli were evaluated. Seven treatments consisting of five Trichoderma strains, one Colletotrichum capsici and control were used as seed treatments. Chilli seeds were treated with spore suspension or secondary metabolites of each Trichoderma species/strain and C. capsici separately. Mixture of suspension of each Trichoderma species/strain with C. capsici was also used as spore suspension or secondary metabolites. Percent fruit infection in the control treatment was found almost similar to the treatment that contained T. viridae and T. pseudokoningii spore suspension or secondary metabolites. T. harzianum strains alone suppressed fruit infection (%) significantly. Further all the Trichoderma species/strains reduced the fruit infection (%) than the diseased control even when seeds were treated with Trichoderma separately mixing with C. capsici. Spore suspension of T. harzianum IMI-392433 was found much more effective against C. capsici which suppressed 95.8% and 79.6 % fruit infection respectively under natural (without C. capsici) and high inoculum pressure of C. capsici. All the tested Trichoderma species/strains showed higher plant growth and increased fruit yield irrespective of rest of the treatments. It was found that Trichoderma strains control chilli fruit rot significantly but high inoculum pressure of C. capsici reduced fruit yield drastically. Among the treatments, spore suspension of T. harzianum IMI-392433 increased the fruit yield 83.6% and 76.5% per plant compared to spore suspension of C. capsici and control treatments, respectively. These results implied that T. harzianum IMI-392433 can effectively control fruit rot of chili caused by C. capsici through host resistance and antifungal metabolite activity. The fruit yield was increased due to the influence of T. harzianum IMI-392433 on vigorous physiological growth of plants as well as efficacy against the disease. The Agriculturists 2018; 16(2) 75-87

Three different plant extracts (Khaya ivorensis, Azadirachta indica and Daniella oleifera) and two Trichoderma species (T. harzianum and T. atroviride), singly and in combination, were assessed on nematode population changes and also in the control of plant parasitic nematodes on tomato under field condition during 2018 and 2019 planting seasons. During each trial, plant parasitic nematodes encountered in the field were Meloidogyne, Pratylenchus, Xiphinema and Helicotylenchus species. The experiment was a randomized complete block design with 4 x 3 factorial scheme and five replications. Factor A being plant extracts (Khaya ivorensis, Azadirachta indica, Daniella oleifera) and control, and factor B being bio-control agents (Trichoderma harzianum, T. atroviride) and control, resulting in 12 treatments. Significant reductions were observed on the population of the plant parasitic nematodes at all treatment levels with neem plant extract, in combination with either T. harzianum or T. atroviride resulted in the greatest significant decrease. Applications of different plant extracts and Trichoderma species, singly and in combination, enhanced the growth and yield of tomato infected with parasitic nematodes.

Tomato a highly nutritious and income relevance crop. The optimum productivity is constrained by a number of factors such as soil fertility management. A field experiment was conducted at Teaching and Research Farm, Federal University of Technology, Akure, Nigeria between December 2012 to April 2013 (irrigated) and March – August 2013 (rainfed) to investigate the effect manuring on the growth and yield of tomato varieties. Four manuring sources (Organic, Organo-mineral, Urea and No fertilizer) and four tomato varieties (Beske, Ibadan local, Roma and UC) laid out as a randomized complete block design in a factorial arrangement and replicated three times. Results showed that manuring influenced on set of flowering in tomato, organic fertilizer prolonged day to anthesis (22.72 day) closely followed by organomineral (22.49 days) while control (no fertilizer) was earliest (20.88 days). Beske significantly showed earliness to flowering, Ibadan local and Roma were delayed but had similar flowering dates (P≤ 0.05). The varieties had distinct fruit yield responses to fertilizer application, fruit produced were in order of Beske, Ibadan local and UC (721.9;626.4) g;(683.6; 696.2) g; (550.0; 463.6) g (384.4; 431.5) g for rainfed and irrigation respectively. Varietal effect was significant on fruit yields for irrigated, Beske recorded heaviest fruit yield (6.03g) followed by Ibadan local (4.72), Roma (2.6) and UC (2.14). Harvested fruit among the varieties in both seasons were (3978.5t/ha;3484.9t/ha;1229.8t/ha and 985.2 t/ha) and (3947.2t/ha; 3452.8t/ha; 1197.8t/ha; 953.2t/ha) for Beske, Ibadan local, Roma and UC respectively. Fertilizer application were significant for both season on harvested fruits weight in magnitude order of Organomineral, organic fertilizer urea and control (3535.9;3503.9t/ha),organic fertilizer (2935.2;2903.2t/ha), Urea (2078.8;2047.4t/ha) and control (1128.0;1096.5t/ha). Beske and Ibadan local varieties performed better in the rainforest zone of Nigeria. Organic fertilizer sources complimented with mineral fertilizer timely applied with good agronomic managements are measures to enhance growth and yield performance of tomato.

Three popular tomato varieties namely, Ratan, BARI tomato-3 and BARI tomato-6 were experimentally evaluated to identify the potential mulch on growth and yield, where the experiment consisted of four mulching treatments viz. water hyacinth, straw, am-ada leaf and banana leaf with a control (no mulch). The experiment was conducted under rainfed condition. In the experiment, mulching showed significant effect on growth, yield components and thus on the yield of tomato. Yield contributing characters were significantly higher when water hyacinth mulch was used. The variety Ratan produced the highest (53.74 t/ha) fruit yield, while BARI tomato-3 showed the lowest (48.89 t/ha) fruit yield. The combination of mulching and variety exhibited significant variation in some yield components and yield. The combination of water hyacinth and Ratan produced the maximum yield (62.16 t/ha) and thus the experiment revealed that water hyacinth and straw mulches have potentiality to increase the yield of tomato.

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.

To study the effects of cover methods and nitrogen (N) levels on the growth and yield components of tomato Cv. Pear F1, field experiments with a 4x3 factorial design were conducted in the 2019 spring and winter seasons using a randomized complete block design with three replications. The cover methods included four treatments: bare soil (BS), black plastic mulch (BPM), transparent polypropylene row cover (RC), and a combination of BPM and RC (BPMRC) with the RC removed approximately 30 days after transplanting. Nitrogen (N) was applied at three levels (150, 180, and 210 kg N ha-1). Using BPM and RC generally led to an increased air temperature, air humidity, soil moisture, and soil temperature compared to the BS treatment. Higher N rates (180 and 210 kg N ha-1) did not result  in different tomato fruit sizes and fruit weights but positively increased fruit yield and quality (Brix values and fruit dry weight) as compared to the 150 kg N ha-1 addition. The cover methods positively affected the yield components and fruit yield of tomato as well as the fruit characteristics compared to the BS treatment. Using cover materials (BPM and RC) combined with a higher N application significantly increased the yield attributes and fruit yield. The highest fruit yield was achieved under the mulching treatment by black plastic (BPM treatment) combined with a 210 kg N ha-1 application, resulting in 50.90 tons ha-1 in the spring and 58.27 tons ha-1 in the winter.

<p>Temperature rise is one of the most challenging climate change impacts that increase the intensity of heat stress. In this investigated the production of celery (<em>Apium graveolens</em> var. <em>rapaceum </em>F1 hybrid)) was tested during the late season. The experiment was carried out during the two successive summer seasons of 2019 and 2020 in Giza Governorate, Egypt. The experimental design is a split-plot, the main plots consist of three low tunnel cover treatments, and three spray treatments with three replicates in sub-main plots. Results showed that the use of white net cover gave the highest vegetative growth and yield followed by the black net. Values of plant yield were 951, 765, and 660 g/plant for white, black and without cover, respectively, in the first season. The foliar application of 3 mM of potassium silicate produced the highest vegetative growth and yield compared to the control treatment. Referring to the effect of spray foliar application of potassium silicate on yield 1.5 mM (S1), 3 mM (S2), and control were 892, 795, and 689 g/plant in the first season, respectively. The best combination that delivered the highest vegetative growth and yield was a cover low tunnel with a white net combined with S2 foliar application.</p>

Exploring ways to improve stand establishment and crop productivity under abiotic stresses like drought is important. Two years experiments were conducted at University of Agriculture, Peshawar-Pakistan to examine the efficacy of six pre-sowing seed hardening agents. Seeds of wheat cultivar Uqab-2000 were hardened in six different chemicals of various concentration viz; PEG-8000 (10%), CaCl2 (4%), KNO3, (3%), Mannital (4%), NaCl (5%), Na2SO4 (2%) along with water soaking and dry seeds as control for 24 hours and drying back to original moisture content at room temperature. The soaking and drying of seeds was repeated twice for 12 hours. The results showed that pre-sowing hardening of seed with PEG-8000, CaCl2 and KNO3 gave higher germination, decreased days to 50% germination, increased shoot length, root length, seedling fresh and dry weight in laboratory experiment as compared with other hardening and control treatment. Under field conditions, maximum plant height (93.53cm), spikelet’s spike-1 (17.16), grains spike-1 (50.82), 1000 grain weight (39.97 g), grain yield (3482 kg ha-1) and maximum harvest index (32.5%) were observed in PEG-8000 hardened seed than control treatment (2872 kg ha-1). Seed hardened in PEG-8000, CaCl2 and KNO3 gave 30% increase in grain yield as compared to Mannital, NaCl and Na2SO4 which gave 15% increase in grain yield over control treatment.
