Nutrients Requirement of Ashgourd (Benincasa bispida cogn.)Under Degraded Soils of Alluvial Region of Uttar Pradesh
Abstract
The field experiment was carried out during rainy season of 2009-10 and 2010-11 in the catchments area of left bank of Yamuna River. The study was made under “Farmers Participatory Action Research Programme on Water/Rain Water Harvesting (Scheme of Ministry of Water Resources, New Delhi)” for carring out the research programme on important technologies of water harvesting. The soil of experimental area was light loam with low plant nutrients status. The four treatment i.e., 20 kg N + 20 kg P2O5 + 40 kg K2O/ha, 40 kg N + 30 kg P2O5 + 60 kg K2O/ha, 60 kg N + 40 kg P2O5 + 80 kg K2O/ha and 60 kg N + 40 kg P2O5 + 80 kg K2O + 250 q FYM/ha were tested. The improved cv. Kashi Dhawal was planted between 10-15 July after rainfall during both experiment years and harvested after 110-115 days after planting. Application of 60 kg N + 40 kg P2O5 + 80 kg K2O + 250 q FYM/ha yielded single fruit by 5.65 kg, followed by 60 kg N + 40 kg P2O5 + 80 kg K2O/ha (5.20 kg weight/fruit). The lowest single fruit weight was noted under 20 kg N + 20 kg P2O5 + 40 kg K2O/ha as 3.80 kg/fruit. The applied dose of 60 kg N + 40 kg P2O5 + 80 kg K2O + 250 q FYM/ha registered highest fruits yield by 603.00 q/ha, followed by 60 kg N + 40 kg P2O5 + 80 kg K2O/ha (566.00 q/ha). The lowest yield was recorded at 20 kg N + 20 kg P2O5 + 40 kg K2O/ha by 350.00 q/ha. Fruits store up to six month with the waxination of stem end with wax under open environment without any natural hazards.
