Abstract

A 2-year study conducted to determine the effect of integrated nutrient management on yield and quality of basmati rice varieties in non-traditional area with 54 plots in split plot design. Variety HUBR 10-9 produced 18.8% higher mean grain yield and superior quality parameters than HUBR 2-1. Mean milling, head rice recovery, amylose content and alkali digestion value noted higher with HUBR 10-9 by 4.1%, 4.1%, 8.5% and 15.1% over HUBR 2-1, respectively. Addition of 75% recommended dose of fertilizers with 25% recommended dose of nitrogen as farmyard manure produced higher mean values by 3.1%, 4.2% and 4.0% for hulling, milling and head rice recovery respectively over 100% recommended dose applied as inorganic sources. Combined use of bio-inoculants (blue green algae plus Azospirillum) exhibited higher values for yield and quality parameters. HUBR 10-9 be grown using 75% recommended dose of fertilizers with 25% nitrogen as farmyard manure and blue green algae plus Azospirillum for enhancement in yield and quality in non-traditional areas of eastern Uttar Pradesh. Further investigation required under diverse conditions.

Highlights

Rice (Oryza sativa L.) is the second most important food crop for more than half of the world population, provides carbohydrates, proteins, vitamins and is an important source of nutrients due to its every day consumption (Heinemann, Fagundes, Pinto, Penteado, & Lanfer-Marquez, 2005)
Yield enhancement with HUBR 10-9 was due to improvement in growth parameters, yield components, translocation of photosynthates from source to sink and genetic makeup of genotype
Bio-inoculants followed the order of B3, B1 and B2 (Table 1)

Summary

Introduction

Rice (Oryza sativa L.) is the second most important food crop for more than half of the world population, provides carbohydrates, proteins, vitamins and is an important source of nutrients due to its every day consumption (Heinemann, Fagundes, Pinto, Penteado, & Lanfer-Marquez, 2005). Popular basmati rice varieties traditionally grown namely Basmati 370, Basmati 386 and Taraori Basmati are low yielder, tall in stature and lodge at higher levels of inorganic fertilizers. Growing of these cultivars in non-traditional areas causes reduction in grain size and aroma with enhanced breakage. Climatic limitations restrict cultivation of basmati rice in non-traditional areas because of inferior quality and are a major constraint. Temperature plays vital role on grain quality in non-traditional areas. Higher temperature during grain filling affects the yield and amylose content of basmati rice (Ahmed et al, 2015). Genotypic factor is considered as most prominent which determines the plant response to different soil conditions and other external factors (Chandel et al, 2010)
