Abstract
The field investigation entitled “Effect of seaweed extract on growth and yield of soybean (Glycine max (L.) Merill)” was conducted at Experimental field, Central farm, Balsa, VNMKV, Parbhani. The experimental field was leveled and well drained. The soil was clayey in texture, low in nitrogen (196.50 kg ha-1), low in phosphorus (12.90 kg ha-1), rich in potash (518.70 kg ha-1) and alkaline in reaction. The environmental conditions prevailed during experimental period was favorable for normal growth and maturity of soybean crop.
The experiment was laid out in Randomized block design with seven treatments viz., T1- Control, T2- 75% RDF (22.5:45:22.5 NPK kg ha-1), T3- 100% RDF (30:60:30 NPK kg ha-1), T4- 75% RDF + @ 20kg SG (Seaweed extract in granular form) + @ 2ml SL (Seaweed extract in liquid form), T5- 75% RDF + @ 40kg SG + @ 2ml SL, T6- 100% RDF + @ 20kg SG + @ 2ml SL, T7- 100% RDF + @ 40kg SG + @ 2ml SL and 3 replications. Sowing of soybean variety MAUS-71 was done on 14th July, 2017 by dibbling the seeds at spacing 45 cm × 05 cm. The recommended cultural practices and plant protection measures were taken. Fertilizer viz., nitrogen, phosphorus and potassium were applied to respective plots by using urea, SSP and muriate of potash uniformly in the lines opened for sowing as per the treatments. The crop was harvested on 29th October, 2017.
Application of 100% RDF + @ 40kg SG + @ 2ml SL (T7) recorded significantly higher growth attributes, yield attributes, seed yield (2232 kg ha-1), straw yield (2879 kg ha-1) contributing characters and GMR (70,955 Rs ha-1) followed by application of (T6), (T5) and T7 was significantly superior over the rest of the all treatments. The significantly lower growth attributes, yield attributes and seed yield of soybean was observed in control (T1). The higher net monetary returns was recorded (37,280 Rs ha-1) with the application of (T7) and followed by T6 and T5 treatments. The lower net monetary returns were recorded with control (T1). The higher benefit: cost ratio was recorded with the application of (T6) and the lower benefit: cost ratio was recorded with control (T1).
On the basis of above findings it may be inferred that for getting maximum yield of soybean net returns and B: C ratio, application of 100% RDF + @ 20kg SG + @ 2ml SL (T6) was found effective in increasing production of soybean crop.
