Effect of cultivars and nutrient levels on productivity and profitability of rice

A field experiment was conducted during kharif season of 2019 to assess the effect of cultivars and nutrient levels on productivity and profitability of wheat. The experiment was conducted in randomized block design with three replications. The treatments consisted of four cultivars of rice Viz. Basmati-370, Jammu Basmati-123, Jammu Basmati -118 and Jammu basmati-138 and four levels of nutrient viz. Control, 15:10:5 kg/ha N:P₂O₅:K₂O, 30:20:10 kg/ha N:P₂O₅:K₂O and 45:25:15 kg/ha N:P₂O₅:K₂O. The soil of the experimental site was sandy clay loam in texture, slightly alkaline in reaction (7.42), low in organic carbon (4.73 g/kg) and available nitrogen (247.06 kg/ha), but medium in available phosphorus (14.28 kg/ha) and potassium (149.60 kg/ha). The experimental results revealed that Jammu Basmati-138 (41.62 q/ha) recorded higher grain yield which was followed by Jammu Basmati-123 (39.82 q/ha) and Jammu Basmati-118 (38.35 q/ha) at fertility levels of 45:30:15 kg N:P₂0₅:K₂O/ha and the% increase of these Basmati cultivars over Basmati-370 were to the tune of 12.46, 16.87 and 22.05%. Likewise, Jammu Basmati-138 recorded highest net returns ( Rs 78078.98/ha) and B:C ratio (1.71) with 45:30:15 kg N:P₂0₅:K₂O/ha.
