Performance of Tomato with Organic Manures in Plastic Tunnel

Abstract

Tomato is one of the most demanded vegetable with increasing trend of commercial cultivation in Nepal. As it is the heavy feeder crop thus soil nutrient management has been always challenging. Since, in modern world organic production has been favored by consumers for many reasons thus we aimed to compare the efficacy of various compost, mineral fertilizers and their combinations in tomato production and soil productivity. For the purpose a field experiment in plastic tunnel was carried out in Horticulture Research Division, Khumaltar in two consecutive years (2014 and 2015). Srijana, a popular tomato hybrid among commercial producers, was purposively selected. Eight treatments (control, recommended doses of chemical fertilizers, compost 15 t ha -1 + cattle urine, compost 10 t ha -1 + cattle urine, compost 12.5 t ha -1 + cattle urine, compost 15 t ha -1 + 1/4 recommended dose of chemical fertilizers, compost 10 t ha -1 + ¾ recommended dose of chemical fertilizer and compost 12.5 t ha -1 + 1/2 recommended dose of chemical fertilizer) were laid out in randomized complete block design and replicated thrice. The result showed significant (p < 0.05) positive correlation between the plant height and yield of tomato. The treatment with compost dose of 12.5 t ha -1 with half dose of recommended dose of chemical fertilizers produced the highest incremental yield (85% increment) over other treatments followed by compost 15 t ha -1 with cattle urine. Addition of soil organic carbon, soil nitrogen, soil potassium by the increasing level of compost though not significant, but increment in carbon content, nitrogen content and potassium content of soil observed in successive years. For commercial producer at plastic tunnel, compost at the rate 12.

Diamondback Moth Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae); A Real Menace To Crucifers And Its Integrated Management Tactics

“…Vegetable cultivation seems to be one of the most productive businesses for food security and cash generation in the city's proximity, where agriculture is the primary source of income and livelihood (Rai et al, 2019). Commercial farming is becoming more popular day by day in Nepal (Shrestha et al, 2018). Over the last two decades, intensification of agriculture and increased production of Cruciferous Brassica vegetable crops have increased the pest status of the diamondback moth (DBM), Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae), (Furlong et al, 2013).…”

Evaluation of lures for monitoring the population of thrips and whitefly in the major horticultural crops in Nepal

“…Insect pests play a major role for declining the yield of horticultural crops. In Nepal, commercial farming has increasing trend (Shrestha et al, 2014(Shrestha et al, , 2018 and it shared a larger fragment of urban agriculture in Kathmandu Valley as the profitability attracted farmer day by day. The crop loss due to pest is estimated to be 35-40% of the total production (PPD and FAO, 2004).…”
