Effect of organic manures on growth and yield of summer cowpea [Vigna unguiculata (L.) Walp] under middle Gujarat conditions

Abstract

An experiment was carried out on loamy sand soil of Bidi tobacco Research Station Farm, AAU, Anand to evaluate the effect of organic manures (farmyard manure, vermi-compost, poultry manure, neem cake and castor cake) on growth and green pod yield of cowpea during summer season of 2013-14 in randomized block design with four replication. Application of recommended dose of fertilizer 20-40-0 NPK kg ha -1 recorded significantly higher green pod, stover yield and yield contributing characters viz., number of green pods plant -1 , number of seeds pod -1 over different organic sources; However, application of 2 t ha -1 vermicompost was at par with RDF. The plant population per meter row length at 25 DAS and at final picking and number of branches plant -1 and plant height at 30 DAS showed no significant difference between different treatments, but at 60 DAS and at final picking significantly higher plant height was observed due to use of RDF 20-40-0 NPK kg ha -1 .

Effect of Organic Manures, Organic Supplements and Biofertilizers on Growth and Yield of Cowpea [Vigna unguiculata (L.) Walp]

“…The above findings are in confirmation with the research findings of Shrikant (2010) and Erdal et al, 2008. Vermicompost treatments greater root extension under biofertilizers application might have helped in greater uptake of nutrients which ultimately improved the yield attributing characters like pod length, pod yield, pod weight, number of pods per plant and number of seeds per pod (Joshi et al, 2016).…”

Root Development and Nodulation in Cowpea as Affected by Application of Organic and Different Types of Inorganic/Plastic Mulches

“…Increased weight of root nodule in organic mulch treatment might be due to favourable effect of paddy straw organic mulch in improving the overall physical, chemical and biological attributes of the soil and thus improving root symbiosis process with soil nodule rhizobacteria thereby enhancing root nodulation activity of Rhizobium in the soil. Similar results were reported by Goud et al, (2010) and Joshi et al, 2016. On the basis of the results obtained from the current study, it is clear that use of various organic and plastic/inorganic mulches has profound effects on root development and root nodulation in cowpea plants, however, application of different irrigation level has resulted in the variable type of findings. Among various treatments of organic and plastic mulches, organic mulches application has positive effects on most of the parameters associated with root development and nodulation, while it was negatively affected by black mulches.…”

The Effect of Iron, Zinc and Organic Fertilizer on Yield of Chickpea (Cicer artietinum L.) in Mediterranean Climate

“…Overall findings showed that in studied area modern agriculture based on only chemicals fertilizer will not be prosperous because of many problems such as poor soil condition, imbalanced nutrients, surface and ground water pollution from fertilizers and sediments impending shortages of non-renewable resources and low farm income from high production costs (Joshi et al, 2016). However, there is increasing awareness of the need for corrections in nutritional management in chickpea production system in semi-arid region.…”

“…Moreover, in normal soils with some organic matter content, exchangeable cations such as Ca 2+ and Mg 2+ link clay particles to humic acids of the organic matter, generating stable micro-aggregates which are the basis for soil structure, porosity, and internal drainage (Machado and Serralheiro, 2017). Furthermore, modern agriculture based on merely chemicals is not sustainable because of many problems such as loss of soil productivity from excessive erosion and associated plant nutrient losses, surface and ground water pollution from pesticides, fertilizers and sediments impending shortages of non-renewable resources and low farm income from high production costs (Joshi et al, 2016).…”
