Impact of weather parameters on yield of groundnut (Arachis hypogaea L.) under varied environmental condition in Parbhani district of Maharashtra

Abstract

An experiment entitled 'Impact of weather parameters on yield of Groundnut (Arachis hypogaea L.) Under varied environmental condition in Parbhani district of Maharashtra was conducted at research farm of cotton research station, college of agriculture, Parbhani during summer season 2018. The field experiment was laid out in split plot design with five replications. there were forty treatments combinations comprising of four date of sowing viz. 3rd SMW, 5th SMW, 7th SMW and 9th SMW as main plot treatment with two irrigation methods as sub plot treatment viz T1 (drip irrigation) and T2 (furrow irrigation). The gross and net plot sizes were 4.2 x 7.5 m2 and 3.2 x 6.5 m2, respectively with spacing of 30 x 10 cm. The growth parameters like plant height, number of functional leaves, number of branches per plant, dry matter production were significantly influenced by the dates of sowing. The results revealed that groundnut sown in first date of sowing (D1-3rd SMW) with treatment T1 (Drip irrigation) is significantly higher growth and yield parameters due to more number of pods, number of grains per pod and 1000 seed weight, followed by D2 (5-SMW). Among treatment T1 (drip irrigation) (2017.2 kg/ha) recorded highest grain yield over T2 (furrow irrigation). The duration of crop growth stages were influenced by the sowing dates.
