APPLICATION OF BIO-FERTILIZERS SUPPLEMENTED BY NPK AND BORON FOR ENHANCING GROWTH AND YIELD OF BREAD WHEAT

Abstract
ABSTRACT Bread wheat is one of the major economic crops, but its productivity is compromised due to low soil fertility and nutrient availability; hence, it has become a significant challenge for farmers. Recently, more emphasis is being inflicted on sustainable agriculture, and biofertilizer is considered one of the main driving factors, supplemented with Boron and NPK. For this purpose, a two-year study (2017-18 and 2018-19) was conducted to investigate the synergistic effects of two biofertilizers (Biozote @ 2.5 kg ha-1 and CC7 @ 5 kg ha-1), boron (B1 @ 1 kg ha-1, B2 @ 2 kg ha-1) and half of the recommended dose of NPK @ 50-40-30 kg ha-1 on various agronomic and yield contributing traits of wheat. A randomized complete block design was employed with three replications and seven treatments (Control, NPK+B1, NPK + B2, NPK + Biozote + B1, NPK + Biozete + B2, NPK + CC7 + B1, NPK + CC7 + B2) during both years. Wheat growth and productivity increased when Biozote and Boron were used with NPK. Results showed highly significant variability for treatment effects for all the studied traits, whereas years and interaction of treatments and years remained non-significant. According to the findings, two treatments, viz., NPK + Biozote + B2 and NPK + CC7 + B2 were found best promising amongst all treatments. Among yield contributing traits, number of plant m-2 (77 and 78), number of grain spike-1 (41 and 42), grain weight spike-1 (2.37 g and 2.46 g), thousand-grain weight (46.88 g and 47.10 g), and grain yield (2009 kg ha-1 and 2018 kg ha-1) were the highest with the treatment of NPK + Biozote + B2 for wheat crop in 2017-18 and 2018-19. Conclusively, it is observed that biofertilizer and Boron can improve wheat growth, development, and productivity, even with half of the recommended dose of NPK, which may have relatively lower economic input estimates than the full and recommended dose of NPK.
