Effect of Detopping Practice on Growth Parameters and Yield of Rabi Maize (Zea mays L.)
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2017, Vol 6, Issue 8
Abstract
A field experiment was conducted at College of Agriculture, Professor Jayashankar Telangana State Agricultural University, Hyderabad, India, in rabi 2014-15 to study the effect of different stages and different heights of detopping on growth parameters and yield components of maize (DHM-117). The experiment was laid out in a randomized block design comprising of a factorial combination of three stages of detopping viz., D1-10 days after silking, D2-20 days after silking and D3-30 days after silking and three heights of leaves detopping viz., L1-detopping up to two leaves, L2-detopping up to four leaves, L3-detopping up to six leaves with a control and replicated thrice. The results revealed that, higher plant height, number of leaves, LAI, dry matter production and yield were recorded in control (no-detopping) than the treatments. However, detopping at different stages did not show significant effect on these parameters, but highest dry matter production and yield were observed with D3 (detopping at 30 days after silking) and lowest in D1 (detopping at 10 days after silking). In case of different heights of detopping more plant height, no. of leaves, LAI, dry matter and yield were observed in L1 (detopping up to 2 top leaves) and lowest in L3 (detopping up to 6 top leaves). SPAD readings were not affected by either different stage of detopping nor different heights. It was inferred that leaves which are adjacent to the cob (especially two above the cob) has more leaf area to produce more dry matter hence yield.
