Impact of simple agro-ergonomic practices adoption in mulberry cultivation for natural resources saving; cost reduction and increase income to sericulture farmers
Publication Date : 04/03/2018
Scientific way of practicing sericulture through timely adopting recommended simple agro- ergonomic practices in the field at famers’ level has brought tremendous improvements on the utilization efficiency of natural resources like irrigation water, manpower, fertilizer input involved in mulberry cultivation and in silk worm cocoon crops, with increased quality linked productivity of mulberry leaves facilitated more disease free silkworm layings (dfls) brushing and quality cocoon production at less cost which doubled net income to farmers tackling constraints on irrigation water, skilled workers non- availability, its high costs and increased prices of inputs. Soil nutrients status of mulberry garden of 100 sericulture farmers @ 20 from 5 regions tested revealed that average organic carbon content of 0.64% (0.07-1.36%), phosphate 16.07 (5.4- 32.1 kg/ha) and high in potash of 545.99 (89.6-985.6 kg/ha) with average 7.76 pH (6.41-9.12) and electrical conductivity 0.20 (0.034-0.956 mmhos/cm). All the farmers identified were sensitised on the basic principles and importance of recommended simple agro-ergonomic practices adoption in time and closely monitored for one year (2016-’17). The studies revealed that significant improvements on the utilization efficiency of all direct measurable economic inputs with adopted farmers. Irrigation Water Use Efficiency (WUE) in terms of leaf productivity per ha mm irrigation water used increased to 131.11% with 60.31% irrigation water savings; Human Resource Use Efficiency (HRUE) in terms of work output man days utilised increased to 103.85% with equal man days savings; Fertilizer Use Efficiency (FUE) in terms of leaf productivity increased to 44.18%. Quantum of dfls rearing & production of cocoons per unit area increased to 25 & 49.26% respectively, whereas the overall production cost decreased by 44.62% and the net income through sale of cocoons alone with quantum jump increase of 129.33% more when compared to the non-adopters. The study details are discussed in the paper.
