Abstract

Present experiment was conducted in participatory mode among ten tomato growers of Chatra district of Jharkhand during late Rabi of 2009-10 to summer 2010 including three technology options viz., Farmers practices i.e. plots provided with required number of irrigations without mulching (TO₁), use of black plastic mulch (TO₂) and use of rice straw mulch applied @ 10 t/ha to maintain 2 inch thickness (TO₃). Mulched plots were also irrigated whenever required to maintain soil moisture. Data were recorded on moisture content after one week of irrigation (%), number of irrigations during 130 days of crop duration, irrigation intervals (days) required to maintain at least 20-22 per cent soil moisture, weed population per m2 area, fruit weight (g), fruit yield per plant (kg), yield (q/ha) and C:B ratio. Results indicated that black plastic mulch was promising for increasing soil moisture content after one week of irrigation, fruit weight and reducing number of irrigations and weed population per m2 area but rice straw mulch increased number of fruits per plant and fruit yield. Rice straw mulching also exhibited maximum B:C ratio due to higher fruit yield and lower initial input required in application of this locally available mulch material . Therefore, it is recommended for large scale application in summer tomato crop for remunerative yield.

Abstract

Present investigation was conducted during summer-rainy season (March-July) of 2013 in the temperate hills of Tehri-Garhwal, Uttarakhnad (2000 m altitude, 78°24' E longitude and 30°18' N latitude). Among the treatments planting geometry e.g. single row (60x20 cm) and paired rows (15 cm apart paired rows at 60 x20 cm) and irrigation systems viz., furrow and drip with or without dried grass mulching were tested in all possible combinations across the varieties viz., Kufri Girdhari and Kufri Himalini. In paired row planting, tubers of 20±5 g weight were planted in 15 cm apart paired-rows on ridges spaced at 60x20cm (centre to centre) as against seed tubers of 40-50 g in single row planting geometry at 60x20 cm spacing and thus, the seed rate in all treatments was kept constant (20 q/ha). Results indicated that Kufri Himalini was found to be promising for tuber yield (30.7 t/ha) as affected by combination of planting geometry and irrigation system. Among the cultural practices, paired row planting geometry accompanied with furrow irrigation system (T₅) was found to be the best cultural combination for tuber yield (35.2 t/ha). The combination of paired row planting geometry and drip irrigation system (T₇) was second most important treatment (33.1 t/ha). When cultivars and cultural combination are considered simultaneously, Kufri Himalini exhibited maximum tuber yield in paired row planting system accompanied with furrow irrigation (36.3 t/ha) followed by at par values of Kufri Girdhari in paired row planting system accompanied with furrow irrigation (34.0 t/ha). Based on the results it could be concluded that two varieties of potato Kufri Girdhari and Kufri Himalini responded well to paired row panting geometry. Among the cultural packages paired row planting + furrow irrigation was most promising combination for tuber yield (35.2 t/ ha) followed by paired row planting + drip irrigation (33.1 t/ha) in temperate Himalayas.
