Effect of tillage and crop management practices on phenology, productivity and energetics of potato under north-western Himalayan conditions
Keywords:
<i>Solanum tuberosum</i> L., Tillage, Energetics, Organic farming, Natural farmingAbstract
The experiment comprising of three tillage practices viz. conventional tillage (CT), minimum tillage (MT) with furrow and minimum tillage flat-bed (MTF) as main-plots and three crop management practices (CMPs) viz., organic farming (OF), natural farming (NF), and natural farming + FYM as sub-plots was conducted under a split plot design with three replications during rabi seasons of 2022-23 and 2023-24 at Palampur. Among tillage practices, CT and MT with furrow were more promising for most of the traits than MTF. CT gave significantly higher tuber and haulm yields along with energy output, net returns of energy, energy efficiency, energy intensity and energy productivity over the years. NF + FYM recorded maximum plant emergence, tuber yield, haulm yield, energy output, net returns of energy and energy intensity, whereas energy efficiency and energy productivity had high values under NF without FYM.
