Abstract

AMMI analysis of wheat yield for nano urea formulations treatments had observed highly significant variations due to treatments, locations, and TxL interactions with 44.6%, 33.5%, and 12.8% respectively. Thousands of grains weight of treatments observed that the first AMMI interaction component contributed to 78.9% whereas AMMI2,  AMMI3, AMMI4 accounted for 10.2%, 3.5%, 2.3% respectively. AMMI analysis-based measures ASV & ASV1 have utilized 73.4% of interaction sum of squares and T6, T8, T5 recommended by ASV1 whereas ASV pointed for T6, T8, T5 treatments for wheat yield. Measures MASV1 and MASV based on all significant IPCAs of the AMMI analysis for thousands grains weight and considered 94.9% of interactions sum of squares had recommended T6, T5, T11 and T6, T8, T7 treatments for stable performance respectively. Superiority index measures had considered 65% and 35% of ratios of average value and stable performance in weighted average observed suitability of T8, T3, T6 treatments for wheat yield. Analytic adaptability measures based on BLUP of treatments effects settled for T3, T4, T7 treatments as far as thousands of grains weight was considered in the present study. Biplot analysis observed a very tight positive relationship of ASV with ASV1, W1 , W2, W3, W4, W5, W6, WAASB , MASV with MASV1 values. Analytic measures PRVG , HMPRVG expressed strong bondage with BLUE and  BLUP effects of treatments for wheat yield. The clustering pattern for thousands of grains weight had expressed first consisted of superiority indexes corresponding to mean, GAI, HM of treatments effects irrespective of BLUE and BLUP estimates joined hands in the first cluster and next cluster was of analytic measures PRVG, HMPRVG for treatments effects irrespective of BLUE and BLUP estimates with IPC1 measures in the present study.

Introduction

Wheat (Triticumaestivum L.) has been established as one of the most important cereal crops at the world level [1]. The green revolution of the country observed an Invitation from Acta Traditional Medicine very good response of dwarf wheat genotypes towards inorganic fertilizers [2]. Owing to the growing awareness of the harmful effects of fertilizers, the last decade has witnessed extensive research into biofertilizers, microbiomes, and soil health [3]. More applied fertilizers have shown reduced fertilizers use efficiency through the mechanism of leaching and dnitrification etc [4]. In the last decade, nanotechnology as a novel technology has solved many problems in different fields of science and industry and it has found its position and functions in agriculture [5],[6]. Nano fertilizers are the most important part of nanotechnology in the production phase of agriculture to increase the efficiency of nitrogen fertilizers, reduce the amount of nitrogen fertilizer applied without affecting production, and reducing the risks of environmental pollution on soil and water [7],[8]. Foliar application of nano-fertilizers significantly increased the yield of the crop [9]. Application of nano fertilizers instead of common fertilizers, nutrients are provided to plants gradually and in a controlled manner [10]. The current study was carried out to find out the possible advantages of nano urea formulations treatments with conventional use of urea fertilizer on wheat yield by evaluation under multi-location trials during the last year.

Methods and materials

The thirteen treatments based on nano urea formulations were evaluated at fifteen major locations viz. Delhi, Gurdaspur, Gwalior, Hisar, Jammu, Karnal, Ludhiana,  Pantnagar, Bilaspur, Durgapura, Indore, Jabalpur, Junagadh, Powarkheda, and Vijapur during 2021-22 cropping season to evaluate yield and thousands grains weight wheat genotype by optimizing the nitrogen dose and nano urea formulations under irrigated conditions. The recommended agronomical interventions were followed after thorough ploughing and field layering. One-third of nitrogen along with full phosphorus and potash as basal dose as per treatments and the remaining 2/3rd nitrogen as 1/3rd at first irrigation and 1/3rd at second irrigation wherever required as per treatment. Well-labelled plots were of gross size of 1.80 m x 8 m = 14.40 sq. m. (9 rows at 20 cm spacing). The quantity of Nano urea will be 4 ml /litre of water. The quantity to spray solution will be 400 litre of water/ha. Harvest of net plot size 1.40 m x 7 m = 9.80 sq. m. (7 inner rows x 7 m long) were analyzed statistically by AMMI soft and SAS 9.3 version softwares. A number of AMMI and BLUP  measures [11] are mentioned below for ready reference and details about treatments and locations in table 1.

The stability measure as a weighted Average of Absolute Scores has been defined [12] as

WAASB =

whereWAASBiwas the weighted average of absolute scores of the ith genotype; IPCAikwas the score of the ith genotype (or environment) in the kth IPCA, and EPkwas the amount of the variance explained by the kth IPCA. A superiority index has been devised that allowed  weights  between yield and WAASB as index SI = ; where rGiand rWiwere the rescaled values for yield and, respectively. The superiority index had weighted between yield and stable performance of treatments to be of 65% and 35% respectively.
