Abstract:
A field experiment was conducted during rabi season of 2020-2021 at Experimental Farm Agronomy Section, Oilseeds Research Station, Latur to analyse the effect of various constraint on growth and yield attributes of linseed (Linum usitatissimum L.) in vertisol. The topography of experimental field was uniform and fairly levelled. The soil of experimental plot was clayey in texture, moderately alkaline in reaction having p^H 7.02 with chemical composition such as low in available nitrogen (231 kg ha^-1), very low in available phosphorous (8.57 kg ha^-1) and very high in available potassium (579.80 kg ha^-1). Soil was well drained which was favourable for optimum growth. The experiment was laid out in Randomized Block Design with eight treatments, replicated thrice. The result showed that the application of full package of practices (T₁) recorded higher growth, yield attributes and seed yield (1928 kg ha^-1) in linseed production. Among the different constraints of the single production factor, RDF was found to be the most crucial factor caused yield losses of up to 24%, followed by weeding (23%) and plant protection (18%) as compared to full package of practices. Among the two factor production constraints, RDF combined with weeding (T₅), RDF with plant protection (T₆) and weed management with plant protection (T₇) caused yield reduction up to 49%, 47% and 40%, respectively and was reported as major resource constraints in linseed production. Regarding the combination of three factor production constraints, RDF, weed management and plant protection caused yield reduction of52% as compared to full package of practices (T₁).
