GROWTH AND YIELD ANALYSIS OF TRITICALE UNDER VARIOUS HUMIC ACID AND COMPOST LEVELS
Muhammad Suliman
Abstract
A field trail was carried out at Agronomy Research Farm, The University of Agriculture, Peshawar, during Rabi season 2019-20 to analyse growth and yield of triticale as influenced by various humic acid (HA) and compost levels (CL). The experiment was carried out in a randomized complete block (RCB) design, consisting of four replications. Before sowing, humic acid at the rate of (0, 3, 6, 9 and 12 kg ha-1) in combination with compost (50% domestic waste + 50% FYM) at the rate of (0, 5, 10, 15 and 20 tons ha-1) was used. Prior to application humic acid was mixed with sand and then applied to all plots according to requirement. The size of experimental unit was 2.4 m x 3 m having 8 rows per plot with row to row distance of 30 cm. Seed rate was used at 120 kg ha-1. All the agronomic practices like irrigation and weeding etc. were carried out in a uniformly. The crop was sown on 14th November 2019 and harvested on 21st May 2020. It is obvious from findings that different compost levels significantly influenced growth and yield of triticale. Compost application @ 15 tons ha-1 increased emergence m-2 (131), maximized grains spike-1 (55), average crop growth rate (15.8g m-2 day-1), days to physiological maturity (175), thousand grain weight (51.4 g), biological yield (11782 kg h-1) and grain yield (4960 kg ha-1). Likewise humic acid @ 9 kg ha-1 also improved emergence m-2 (130), spike length (11.6 cm), grains spike-1 (54), average crop growth rate (15.7g m-2 day-1), days to physiological maturity (175), thousand grain weight (51.5 g), biological yield (12227 kg h-1) and grain yield (5205 kg ha-1). Higher flag leaf area (23.96 cm2), harvest index (41%) and days to anthesis (134) were noted when compost was applied @ 10 tons ha-1 and humic acid @ 6 kg ha-1. However maximum spikes m-2 were recorded when compost was applied @ 20 tons ha-1 and humic acid @ 6 kg ha-1. Consequently both humic acid and compost levels enhanced and improved growth and yield of triticale. It was deducted from the experiment that compost @ 15 tons ha-1 along with humic acid @ 9 kg ha-1 accelerated growth and improved the yield of triticale. So for higher grain yield and luxurious growth of triticale, application of compost @ 15 tons ha-1 with humic acid @ 9 kg ha-1 are recommended in study area.
