Improvement of Productivity and Quality of Nepalese Tomato Genotypes Using Black Polyethylene Film as Mulching Material

An experiment was conducted to evaluate the effect of black plastic mulch on yield and other associated characters promising tomato genotypes developed by National Horticulture Research Centre, Nepal at Directorate Agricultural Research, Tarahara, Nepal, during winter season 2019. Nine (HRDTOM 011, HRD 109, HRDTOM 035, 080, 079, 084, 085, 086, Pusa Ruby as a check) were evaluated in randomized complete block design (RCBD) with three replications. Genotypes transplanted 60 cm apart. Analysis variance showed significant differences for marketable fruits per plant, average fruit weight, total unmarketable yield, yield. Among tested genotypes, HARDTOM 011 highest (174) number plant lowest (12.92 g) individual weight. In contrast, 080 produced (36) (49.70 109 provided (69.74 t ha-1) (38.51 yields, respectively. The also obtained from 109. Similarly, 085 035 had soluble solids size, Firmness pH content did not differ among genotypes. With same location (Tarahara), 98% greater demonstrated that production may be significantly boosted use polyethylene film mulching medium Nepal.
