Studies on conventional and organic production system on productivity and quality of garlic

Abstract

A field experiment was carried out in the Research Farm, Department of Horticulture, Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, District Satna (M.P.) during two consecutive Rabi seasons of 2014-15 and 2015-16 to study the Studies on conventional and Organic Production System on Productivity and Quality of Garlic (Allium sativum L.) . The research work was conducted in the Factorial Randomized Block Design with three replications. Each replication was comprised of 18 treatment combinations of three levels of Conventional production system vis. Control-CO, RDF (100% NPK at 100:60:60 Kg. ha-1) C1, 50% NPK (50:30:30 Kg. ha-1) + FYM 5 t ha-1 - C2 and six levels of Organic Production System i.e. Sowing on root days (according to moon) - O1, Vermi compost at 5 t. ha-1 -O2, Treatment of cloves with Bijamrita for 5 minutes at 10 % -O3, Irrigation with Jiwamrita at field preparation and with every irrigation 500 1 ha-1- O4, Panchagavya at 3% Foliar application (30, 60 and 90 days after planting) - O5, Vermi Wash at 10% (30, 60 and 90 days after planting) - O6. The G-282 of garlic variety was used as test crop. The soil of the experimental site having pH 8.43, EC 0.165 dSm-1, organic carbon (%) 0.19, available N, P, and K, 110, 5.08 and 201.80 kg ha-1, respectively. The growth attributes at all growth stage (40, 60, 80, 100 and 120 days), sink parameters at harvest and bulb quality parameters after harvest of crop were significantly affected by conventional and organic production systems during 2014-15, 2015-16 and pooled basis as well. The maximum plant height (), No. of leaves per plant (), length of leaves ( cm), width of leaves, stem girth ( mm), fresh weight of plant ( g) and dry weight of plant was observed in 100% RDF- N:P:K 100:60:60 kg NPK/ha (C1) and minimum in control (C0) at harvest during 2014-15, 2015-16 and their pooled values. Under organic production system the maximum plant height (), No. of leaves per plant (), length of leaves ( cm), width of leaves, stem girth ( mm), fresh weight of plant ( g) and dry weight of plant was observed in treatment vermicompost at 5 t/ha (O2) while, minimum in O1 i.e. Sowing on root days (according to moon). Considering the interaction between both production systems the maximum plant height (), No. of leaves per plant (), length of leaves ( cm), width of leaves, stem girth ( mm), fresh weight of plant ( g) and dry weight of plant was found in treatment O2C1 (Vermicompost at5 t/ha + 100% RDF- N:P:K (100:60:60 kg NPK/ha)) while, minimum in O1C0 (Sowing on root days (according to moon) and control)). newline
