Effect of organic formulations on growth and yield of wheat in South-Eastern Rajasthan

Abstract

A field experiment was conducted at Research Farm of Agricultural Research Station Ummedganj, Kota during rabi season 2020-21 on clay loam soils. The experiment comprised of ten treatments consisted of farmyard manure, vermicompost, ghanjeevamrut and liquid organic manures viz., liquid consortia of biofertilizers, cow urine, vermiwash sasyagavya which were calculated on the basis of 120 kg/ha nitrogen equivalency, which were designed with three replications using randomized block design. A critical examination of data revealed that application of 50% organic manure + 50% vermicompost + vermiwash spray 10% recorded significantly higher plant height (60.22 cm), number of tillers/plant (6.9), chlorophyll content (2.91 mg/g), plant dry weight (75.0 g/mrl) and crop growth rate (7.83 g/m² /day) of wheat over control. Likewise, application of 50% organic manure + 50% vermicompost + 10% vermiwash spray plots exhibited significantly higher number of effective tillers (78.0), ear length (8.63 cm), number of seeds/ear (41.0), test weight (41.50 g), seed yield (4220 kg/ha), straw yield (6383 kg/ha), biological yield (10603 kg/ha), gross return (`145857), net return (`95792) and wheat production efficiency (31.26 kg/ha/day) as compared to rest of treatments. Therefore, application of organic manures combined with vermicompost and vermiwash spray proved better to obtain higher wheat yields under South-Eastern Rajasthan conditions.
