Plant growth, yield, fruit quality and fruit performance characteristics were evaluated for transparent (T1)-, white (T2)-, black (T3)-, silver coated black plastic (T4) mulched, organic mulched, (T5) and non-mulched (T6) peppers (var. Cubanelle) under drip irrigation during winter and summer of 1981-82. Values of plant growth parameters, fruit weight, fruit width and length were significantly higher at 5% level during the winter than during the summer in each treatment thus resulting in increased winter pepper yield. T1 plots caused lowest pepper yield at 5% compared to yield of T2, T3, T4, T5 and T6. The percentage of defective peppers was highest at 5% level during the summer than during the winter. Second harvest had highest fruit weight at 5% level in comparison with third and fourth harvests during the winter and summer.

A study was conducted to assess the effect of drip irrigation and plastic mulch on growth and seed yield of Semialata. Two types of plastic mulch (green and silver/black) were tested at three levels of irrigation (120%, 100% and 80%) by drip irrigation and one level (100%) by furrow irrigation. The daily water requirement of Semialata was estimated by the equation ETcrop= ETox crop factor. ETcrop is crop water requirement mm/day. ETo (reference evapotranspiration, mm/day) was calculated by FAO calculator which uses temperature and humidity data. In this experiments there were twelve treatments were considered. The treatments were replicated thrice. The experiment was laid in randomized block design. It was observed that drip irrigation with or without plastic mulch is yielding better results in terms of growth parameters and seed yield as compared to furrow irrigation without plastic mulch. It was also observed that maximum suppression (67.58%) of weeds resulted with drip irrigation and silver/black plastic mulch at 80% level of irrigation.

AbstractStrawberry (Fragaria x ananassa Duchense ex Rozier) is an important horticultural crop grown in Latvia. The aim of this research was to evaluate some newly introduced strawberry cultivars and perspective hybrids and to evaluate the efficiency of natural calcite leaf fertiliser (Megagreen®) on strawberry fruit quality and spread of pests and diseases. The trial was established in 2012 at Pûre, Tukums Municipality. Cultivars ‘Saint Pierre’, ‘Annapolis’, ’Sonata’, ‘Chambly’, ‘Elegance’, ‘Rumba’, ‘Honeoye’, ‘Senga Sengana’ and two hybrids: 35-1 and 39-1 were included in the investigation. Calcite fertiliser was applied four times per season in 2013 and 2014 by spraying on leaves in concentration 0.5%. Strawberries were grown on two row beds with black plastic mulch and drip irrigation. The evaluation was done for two seasons. Most of the evaluated newly introduced cultivars and hybrids had better fruit quality and resistance to diseases than control cultivars. Cultivars ‘Annapolis’, ’Rumba’, ‘Sonata’, ‘Elegance’, and 39-1 were selected as the most promising related to fruit quality and resistance. The application of calcite fertiliser (Megagreen®) on leaves had no statistically significant effect on strawberry fruit quality and resistance.

Background: Seaweed-derived extracts have gained popularity in agriculture as bioproducts with phytostimulatory effects on plant growth and development. Methods: This study assessed the effect of polysaccharide-enriched extracts (PEEs) derived from six Moroccan seaweeds on tomato growth, yield, and fruit quality. PPEs were applied to tomato plants as soil drench in a greenhouse experiment. Growth parameters including plant height (cm) and number of leaves, flowers, and flower buds were recorded every 15 days. Yield and quality parameters of the harvested fruits were also recorded after each harvest. Results: The obtained results showed that all PEEs improved the growth, yield, and fruit quality of treated tomato plants. According to principal component analysis, the presence of SO4, galactose, glucose, and maltose in the characterized polysaccharides was closely associated with their effect on plant growth, yield, and fruit quality parameters. Conclusions: PEEs obtained from Gelidium crinale,Schizymenia dubyi, Fucus spiralis, and Bifurcaria bifurcata exhibited the highest biostimulant effects and could be used as bioproducts for improved tomato yield and fruit nutritional quality.

Effects of plastic mulch types (transparent - T1, white - T2, black T3, silvercoated black plastic- T4), organic mulch (T5) and nonmulching (T6) were evaluated on growth parameters of drip irrigated summer peppers (Capsicum annuum L. cv. Cubanelle) in the semi-arid southem coast of Puerto Rico. Growth parameters (plant height, secondary and tertiary branches, number of nodes and buds on the primary branch) versus days after transplanting relationships were exponential. Transparent plastic caused lowest plant height and fruit weight. T2, T3, and T4 plots increased pepper yield by 28, 46 and 132%, respectively compared with non-mulched plots and accelerated flowering and fruit set. Relationships among plant height versus fresh pepper weight and growth parameters versus nutrient uptake were linear and the correlation coefficient varied from 0.90 to 0.99.

Two field experiments were doled out during 2014 and 2015 growing seasons to assess tomato growth and yield as affected by some biostimulants and micronutrients with or without mulching type. Certain physiological characters were also examined, plant height, the number of branches per plant chlorophyll a, nitrogen %, red fruit weight and total yield per plant as well as fruit firmness and ascorbic acid concentration in fruit was increased in tomatoes under black plastic mulch compared with bar soil. Application of either biostimulants or micronutrient used to increase all growth and yield characters as well as photosynthetic pigments, ions percentage, and fruit quality. Additive effects were shown under mulching, seaweed extract proved to be the most effective in this respect. It could be recommended that spraying tomato crop at 35 and 50 days from transplanting with 500 mg/l seaweed extract under clear or black plastic mulch in order for inducing the highest yield and improve fruit quality.

Prevalence of heavy soil is a major problem for fruit cultivation under Punjab conditions consequently leading to deficiency of several micro-nutrients including zinc (Zn), iron (Fe), and manganese (Mn) which adversely affects the growth and productivity. In this view, a study was planned to investigate the effect of foliar applications of zinc sulphate (ZnSO4), iron sulphate (FeSO4), and manganese sulphate (MnSO4) on vegetative growth, reproductive growth and fruit quality of papaya cv. Red lady. Plants sprayed with ZnSO4 (0.4 %) exhibited significantly highest plant height, plant girth, number of leaves, petiole length; initiated an earliest flowering and fruiting; and improved fruit quality viz., fruit weight, fruit length, titratable acidity, soluble solids concentrations, ascorbic acid content, total phenols content, and total carotenoids content as compared with the control and all other treatments. In conclusion, foliar application ZnSO4 (0.4 %) significantly improved plant growth and fruit quality in papaya cv. Red lady.

Winter and summer pruning are widely applied processes in all fruit trees, including in peach orchard management. This study was conducted to determine the effects of summer prunings (SP), as compared to winter pruning (WP), on shoot length, shoot diameter, trunk cross sectional area (TCSA) increment, fruit yield, fruit quality, and carbohydrate content of two early ripening peach cultivars (“Early Red” and “Maycrest”) of six years of age, grown in semiarid climate conditions, in 2008 to 2010. The trees were grafted on GF 677 rootstocks, trained with a central leader system, and spaced 5 × 5 m apart. The SP carried out after harvesting in July and August decreased the shoot length significantly; however, it increased its diameter. Compared to 2009, this effect was more marked in year 2010. In general, control and winter pruned trees of both cultivars had the highest TCSA increment and yield efficiency. The SP increased the average fruit weight and soluble solids contents (SSC) more than both control and WP. The titratable acidity showed no consistent response to pruning time. The carbohydrate accumulation in shoot was higher in WP and in control than in SP trees. SP significantly affected carbohydrate accumulation; postharvest pruning showed higher carbohydrate content than preharvest pruning.
