<p>Feasibility of growing muskmelon (Cucumis melo L.), a warm season crop, was studied under a low-input cultivation system in open field condition in high altitude (elevation 3344 m) trans-Himalayan Ladakh region. The marketable yield of five cultivars in different treatments varied from 5.4±0.4 t.ha-1 to 18.8±1.7 t.ha-1 and 4.0±0.2 t.ha-1 to 15.8±1.0 t.ha-1 in 2014 and 2015, respectively. Treatment of black polyethylene mulch (BPM) increased marketable yield by 25 per cent to 155 per cent depending on year and cultivar. The marketable yield of the best performing cultivar (Pusa Madhuras) under BPM was 17.3 t.ha-1, which suggested that muskmelon can successfully be grown in open field condition in trans-Himalaya. The fruit become ready for harvest in mid-August. Number of fruit per plant ranged from 2.3 to 6.3, and TSS ranged from 8.9 to 14.1 °Brix depending on cultivar. Temperature 10 cm beneath the BPM was 2.9±0.4 ºC higher than in bare soil. BPM reduced 74 per cent weed and save 77 per cent time in manual weeding.</p>

<p>Trench greenhouse is a low cost underground rectangular structure (30’×10’×3’; L×W×D) in north-south orientation with stone wall on four sides. It is covered with polyethylene sheet at ground level during winter months. The air temperature inside the trench was found to be 20.7±2.8 °C warmer during day and 7.0±1.2 °C at night that support growing of leafy vegetables during winter (mid October to early March). Three cycles of crops were grown in a year in the greenhouses as against single crop in open field condition in cold trans-Himalayan Ladakh region. Spinach production was 64 kg -70 kg per trench during mid October to early March. Black plastic mulch significantly increased spinach production during winter months. Vegetable seedlings (13,000 to 39,000 numbers per trench) were raised during late March to early May, which is not possible in open field condition otherwise. A variety of warm-season vegetables were harvested (6 kg - 210 kg per trench) from the trenches during summer months.</p>

Cucumis Melo L

Two cultivars (Huanghemi and Elizabeth) of muskmelon (Cucumis melo L.) were evaluated to determine the effect of photon flux density (PFD), leaf temperature, and CO,2 concentration on the net photosynthetic rate (Pn). The cultivars were evaluated under open field and solar-heated greenhouse conditions in northwest China. The Pn increased as the PFD increased, and then the rate of increase in Pn declined for Huanghemi and decreased for Elizabeth. Elizabeth registered 22 µmol m-2 s-1 for light compensation and 1127 µmol m-2 s-1 for light saturation, which, respectively, were 50 and 70% of those required by Huanghemi. The Pn increased with increasing leaf temperatures in the range of 9.8 to 50.8°C. The optimum temperature for photosynthesis was 35.3°C for muskmelon grown in open field, 2.4°C (7%) greater than that for muskmelon grown in the greenhouse. At optimal temperatures, the field-grown muskmelon had the Pn of 19.8 µmol m-2 s-1, 30% greater than that for the greenhouse-grown muskmelon. Both cultivars responded positively to CO2 concentrations of below the CO2 saturation points, whereas Huanghemi exhibited greater (51%) Pn and higher (49%) carboxylation efficiency than Elizabeth at optimal CO2 level. The two cultivars exhibited greater photosynthesis in open field than when grown in solar-heated greenhouses, while Elizabeth performed better than Huanghemi when light conditions were poor. Selective use of cultivars with low requirements for light and temperatures will enhance the photosynthesis and productivity of muskmelon grown in solar-heated greenhouses of northwest China. Key words: Light compensation, light saturation, photon flux density, transpiration

Cucumis Melo L

Growing melon under temperate climate conditions is quite risky due to the high climatic requirements of this species. Vegetable growers use plastic film mulches to heat soil, to reduce weed infestation, and to maintain optimal soil moisture content. The aim of our study was to determine the suitability of white and black plastic film for soil mulching in melon cultivation under temperate climate conditions. Plants of three Polish heterotic cultivars of melon (C. melo L. var. saccharinus Naud.): Emir F1, Junior F1, and Seledyn F1, as well as of the breeding line 61/2014 F1 were the subject of this study. Two soil mulching methods were applied: black polyethylene (PE) plastic film and white PE plastic film, using for this purpose double-sided whiteon-black PE plastic film. The use of black plastic contributed to a significant increase in marketable yield of melon fruits. The content of L-ascorbic acid and carotenoids in fruits of melon grown on white mulch proved to be higher than in those grown on black mulch. The Polish cultivars studied can be considered as tolerant to temperate climate conditions.
