Abstract
Wheat is an important food crop of the world. This crop has wider adaptability due to its genetic makeup. The sowing environment and varieties interaction plays important role in enhancing its productivity and optimum utilization of the resources. As this crop has wider adaptability so we planned our experiment to study the grain yield, heat use and water use efficiency of diverse wheat varieties which have been recommended in different wheat growing zones, sown at different environment in North-western India, to increase the varietal spectrum. A field experiment was conducted during the winter (rabi) season of 2022 23 at Dugurpur village Palka, (Dumdum), Bhabua Block, District Kaimur, Bihar under on Farm Trial by Krishi Vigyan Kendra, Kaimur, to investigate the Integration of Different Forms of Fertilizer on Yield, Yield Attributes and Soil Chemical Properties of Lentil. The experiment was tested in a randomized block design with Farmer Practice (N: P: K: 20:40:00) kg/ha, Technology Option 1 is 50% of RDF + WS 18:18:18: @ g g/l water (Single spray at pre flowering stage) and Technology Option 2 is Seed treatment with PSB + Rhizobium, 50% RDF + WS 18:18:18 @ 5 g/l water (Single spray at pre flowering stage). Results revealed that, yield attributes were significantly higher with Seed treatment with PSB + Rhizobium, 50% RDF + WS 18:18:18 @ 5 g/l water (Single spray at pre flowering stage) followed by Technology Option 1 and minimum yield was recorded in Farmer Practice (Seed treatment + RDF). This treatment also resulted in 12.23 and 6.0% more grain yield with Farmer Practice (15.45 q/ha). The number of pod per plant which resulted in significantly higher in Technology Option 2 (53.13) followed by Technology Option 1 (51.38) and minimum in Farmer Practice (48.25). Thus, Seed treatment with PSB + Rhizobium, 50% RDF + WS 18:18:18 @ 5 g/l water (Single spray at pre flowering stage) are the more productive options for lentil-growing farmers keeping view of the reducing soil fertility.
