| dc.description.abstract | A field experiment was conducted to study the planting geometry and soil moisture conservation practices in late kharif sunflower (Helianthus annuus L.) at the Main Agricultural Research Station (MARS), University of Agricultural Sciences, Dharwad during 2017 in black clayey soil. The experiment consisted seven treatments with five different planting geometries (60 cm × 30 cm, 60 cm × 20, 45 cm × 15 cm, 45 cm × 20 cm and 120 cm × 10 cm) and three land configurations (flatbed, skip row after every two rows of planting and skip row after every two rows of planting with opening furrow in skipped rows). The experiment was laid out in completely randomized block design with three replications. Significantly higher number of green leaves per plant of 22.7 at 60 DAS (days after sowing), leaf area index (1.21, 3.75 and 1.86 at 30, 60 DAS and at harvest respectively), leaf area duration (73.40 and 83.07 days at 30-60 DAS and 60 DAS-harvest respectively) and crop growth rate (0.154 g dm-2 day-1 at 30-60 DAS), seed yield (2,240 kg ha-1), stalk yield (3,589 kg ha-1) and oil yield (868 kg ha-1) were recorded with skip row after every two rows of planting (45 cm × 15 cm spacing) + opening furrow at 30 DAS: 98,765 plants ha-1. Soil moisture content and soil dehydrogenase activity (DHA) were not differed significantly due to planting geometry and soil moisture conservation practices. Skip row after every two rows of planting (45 cm × 15 cm spacing) + opening furrow at 30 DAS: 98,765 plants ha-1 recorded significantly higher seed yield (2,240 kg ha-1) and gross returns ( 78,400 ha-1). However, skip row after every two rows of planting (45 cm × 15 cm spacing): 98,765 plants ha-1 recorded significantly higher net returns ( 49,157 ha-1) and B: C ratio (2.71). | |
