“…This might have been influenced by favourable soil temperature, moisture conditions and depressed weed emergence control as influenced by wood shavings. The present finding was in accordance with Johnson et al (2000), Ansary and Roy (2005) in watermelon and Hanna (2000) in cucumber.…”

Organic weed control methods has a long time record in conserving soil moisture, improving soil structure and increasing soil organic matter. This testimonial should not be left out to manifest on vegetable crops that serve greater part as supplement for balanced meals. Field experiment was conducted in two years (2016 and 2017) to investigate the effects of different organic weed control methods on weed density, phenotypic traits and yield of Cucumber. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The experimental site was marked into (4) blocks while each block was also marked into (3) plots, giving a total number of (12) plots. Plots were 4m x 4m. Two seeds were planted per hole with inter and intra row spacing of 1m x 1m.The results showed that mulched plots (Sawdust and wood shaving) and hoe weeding had higher and significant growth and harvested number of fruits per plant (yield), compared to the control (Weedy and nonmulched plots), this indicated that mulching and hoe weeding as methods of organic weed control have positive effects on reducing weed emergence, increase growth and yield of cucumber. It was concluded that higher yield is not only synonymous to use of synthetic chemicals (pesticides and herbicides) but as well to cost effective and safe organic management practices in breeding programmes.

“…This result strengthens the suitability of black polyethylene film mulch for both dry and wet seasons. Hanna (2000) reported that leaf length, leaf width, plant dry weight, and total yield of cucumber planted next to tomato under black polyethylene film did not differ significantly with white polyethylene film, disproving the unsuitability of black polyethylene film as mulch in a cropping system of tomato -cucumber during summer. One significant problem with the use of white polyethylene mulch was enhanced weed growth beneath the mulch, which would compete with the crop for nutrients and water in addition to reducing the soil-warming effect.…”

Experiments were conducted over 2 years during the dry season of 2002 (June-September) and wet season of 2002-2003 at Regional Research Station, Tamil Nadu Agricultural University, Vridhachalam, India, to study the influence of two colors of polyethylene film mulch (black and white polyethylene film mulch), herbicides (Fluchloralin at 1.0 kg/ha and no herbicide application), and three plant geometries [30 Â 10 cm, 20 Â 20 cm (two seeds/hill), and 20 Â 15 cm] on soil properties, growth, and yield of groundnut. Results indicated that the soil physical properties such as rate of water loss/day was highest with white polyethylene film mulch, the hydraulic conductivity of the soil was significantly more with black polyethylene film mulch, and soil bulk density and percentage of pore space did not differ between the two colors of polyethylene films. The rate of water loss was highest with plots with no herbicide, whereas the hydraulic conductivity of the soil was more with herbicide-applied treatments. However, the bulk density and pore space did not differ significantly. The plant geometry did not have any significant influence on any of the soil physical properties. With regard to soil microorganisms, the bacterial and fungal population was significantly higher in black polyethylene film mulch at all the three stages of observation, whereas no significant difference between the colors of polyethylene film mulch was observed for actinomycetes at all the stages of observations. Interestingly, no variation in the population of soil microflora was observed between the herbicide and no-herbicide treatments. The soil-available nitrogen, phosphorus, and potassium (NPK), at harvest, was significantly higher with white polyethylene film mulch, whereas crop NPK uptake was higher with black polyethylene film mulch. The soil-available NPK and crop uptake was higher with herbicide application. The evolution of carbon dioxide (CO 2 ; soil respiration) was significantly influenced by polyethylene film mulch and herbicides, and the evolution of CO 2 was altered by the plant geometry. The crop dry-matter production, pegging percentage, pod setting ratio number of matured pods/plant, and pod yield were significantly higher under black polyethylene mulch. Herbicide application significantly improved the majority of the growth and yield attributes and significantly higher pod yield was obtained with herbicide application. However, most of the yield and growth attributes and pod yield were not significantly influenced by the different plant geometries studied.

“…[3,4] Root-zone temperatures (RZT) strongly influences plants growth and nutrient uptake. [5][6][7] Economically important crops such as the pepper, potato, tomato, and melon require optimal temperatures in the root zone for maximum growth and yield. [8] Thus, temperature can influence both the Mo concentration and NR activity.…”

Changes in root temperature caused by the application of plastic covers were studied in relation to the uptake and content of molybdenum (Mo) in the different organs of potato (Solanum tuberosum L. var. Spunta) plants (roots, tubers, stems, and leaves) and in relation to nitrogen (N) metabolism. For the semi-forcing technique of mulching, four different covers were used: T 1 (transparent polyethylene), T 2 (white polyethylene), T 3 (coextruded black and white polyethylene), and T 4 (black polythylene). The control treatment had no mulch. The results revealed a positive and significant effect of plastic covers on root temperatures:These thermal differences significantly influenced the Mo concentration, particularly in the T 2 and T 3 treatments in the leaves, roots, and tubers. The same temperatures significantly altered N metabolism in both the aerial and underground parts of the plants, and a strong interrelationship was found between Mo and nitrate reductase (NR) activity. The mulching of this crop proved to be a promising technique in phytoremediation.
