Agronomic evaluation of Gossypium Mrsutum hybrids for varied spacims and nitrogen levels in vertisols under raifed conditions

摘要

A field experiment was conducted on clavev soils at Regional Agricultural Research Station Lam Farm, Guntur under rainfed condition during kharif 2005-06 with the objective,to find out optimum spacing and nitrogen level for pre-released cotton hybrids ufe DHH-263 and Bunny ective to find out optimum spacing (90 chi 60 cm) with 120 kg N/ha was found to be optimum for both the hybbrids. tested, Bunny recorded more net returns (Rs. 3, 800/ha) significantly higher seed cotton yiekftlSn DHH-263 Sinirend w on economic point of view, where Bunny recorded more net r oserve even Neither the spacing adopted nor nitrogen applied caused any I
