Abstract:
〈 p 〉 The influence of black polyethylene mulch (BPM) on growth and yield of tomato was investigated under a low-input cultivation system in arid high altitude (elevation 3344 m) in trans-Himalaya. The mean marketable yield varied from 27.8±2.5 t.ha-1 in open-pollinated varieties with no mulch treatment to 81.2±11.9 t.ha-1 in hybrid tomatoes with BPM. The yield of hybrid tomatoes with BPM is similar or greater than those reported in high-input systems. With BPM, total marketable yield in hybrid varieties increased by 102 per cent and 107 per cent in 2014 and 2015, respectively. Yield increase due to mulching in open-pollinated varieties was 86 per cent and 80 per cent in 2014 and 2015, respectively. Increase in early fruiting under BPM was observed in all the five varieties studied. Difference in soil temperature between mulch and unmulch was significantly higher at early growth stage than during later stages. BPM reduced 57 per cent weed and save 74 per cent time in manual weeding. Incidence of insect-pest and diseases was minimal, and rotten fruit was less than 2 per cent of marketable yield without staking and pesticide or fungicide application. 〈 /p 〉
