Energetics assessment of rice-rice cropping system under different nitrogen management practices

Paper ID- AMA-26-01-2022-11069

This study evaluated energy requirements, gross energy output and energetic indices under different rice establishment methods and nitrogen management practices under rice-rice cropping system. The energy input in normal transplanting (M1) was 3.85 and 3.90 per cent higher than mechanized SRI (M2) during 2017 and 2018, respectively. There was no significant difference in gross energy output, net energy productivity, energy use efficiency, net energy returns and specific energy requirement due to establishment methods. Mechanized SRI recorded significantly higher energy intensity in economic terms (3.13 and 2.93 MJ ₹-1) as compared to normal transplanting (2.71 and 2.56 MJ ₹-1) during 2017 and 2018, respectively. Application of nitrogen as per recommendation of Nutrient Expert with NCU (N1) recorded higher energy input. Application of nitrogen as per recommendation of Nutrient Expert with NCU (75%) + VC (25%) (N2) recorded significantly higher gross energy output and net energy return as compared to nitrogen omission (N5) and absolute control (N6). Application of nitrogen as per recommendation of Nutrient Expert with NCU (75%) + VC (25%) (N2) recorded significantly higher energy use efficiency (EUE) and energy productivity (EP) than all other nitrogen management practices except recommended doses of nitrogen with NCU (75%) + VC (25%) (N4). Absolute control (N6) required significantly higher specific energy. Application of nitrogen as per recommendation of Nutrient Expert with NCU (N1) recorded significantly higher energy intensity in economic terms over nitrogen omission (N5) and absolute control (N6).

Impact of transplanting dates and shock preventing methods on nutrients concentration in grain and stover and their total uptake by pearl millet cultivars

Paper ID- AMA-26-01-2022-11067

A field experiment was conducted on loamy sand soil at the Rajasthan Agricultural Research Institute (SKNAU, Jobner), Durgapura, Jaipur, during two consecutive kharif seasons in 2019 and 2020. The investigation consist of two pearl millet varieties (RHB-173 and RHB-177), transplanting shock preventing methods (No treatment, Triacontanol @ 0.25 ml/litre, Triacontanol @ 0.50 ml/litre and Leaf clipping) and three dates of transplanting (15th June–30th June, 1st July–15th July, and 16th July–31st July) were replicated thrice in factorial randomized block design. Results revealed that the nutrients concentration in grain and stover of pearl millet were merely affected by both doses of triacontanol i.e. 0.25 and 0.50 ml/litre and their total uptake altered by all the experimental variables during individual year of study. The pearl millet cultivar RHB-173 recorded significantly higher grain yield over RHB-177. Among the transplanting shock preventing methods, triacontanol @ 0.50 ml/litre observed statically superior in increasing grain yield of pearl millet as compared to no treatment and leaf clipping, but it was found at par with triacontanol @ 0.25 ml/litre during each year of investigation. The crop transplanted during 1st July to 15th July noted significantly higher grain yield over 1st June to 15th June, however it was found at par with later (16th July- 31st July) transplanted crop.

Effect of Different Application Rates of Organic and Inorganic Fertilizers on Growth and Quality of Wheat (Triticum aestivum l.,)

Paper ID- AMA-26-01-2022-11059

Wheat (Triticum aestivum L.) is the staple food of 40 percent human population across the globe and requires adequate supply of nutrients especially nitrogen for its growth and yield. Therefore, an investigation entitled “Effect of nutrient management in wheat for improving fertilizer use efficiency, productivity and soil health” was conducted to sustain and enhance the productivity and soil health through novel sources of nutrients and their mode of applications on wheat variety DBW 71 with 14 treatments consisting of control, basal applications of recommended NPK(80:60:40)/NPK Granules (200 kg ha-1) + FYM (5 t ha-1) + Bio-stimulant granules ( 62.5 kg ha-1) +NPK Bio-fertilizer(seed treatment) and top dressing of urea 20 (kg ha-1)/ bio-stimulant(625ml/ha)/ NPK Powder (1%) sprays (40/55/70 DAS) in various combinations in RBD with 3 replications at crop research centre of SVPUA&T, Meerut (U.P.) during rabi 2017-19.The soil was well drained sandy loam, low in organic carbon and available nitrogen, medium in available phosphorus and potassium with slightly alkaline pH. The results of the study revealed that wheat when grown with incorporation of FYM +Bio-stimulant –L attainted significantly better growth as reflected by higher plant population, taller plants, higher LAI, LAD CGR,RGR,NAR, and higher dry matter accumulation across the stages. Application of FYM@ 5t/ha+NPK-G@200kg/ha + NPK-bio-fertilizer + Urea @ 20kg/ha and foliar spray of NPK-P @ 1% along with bio-stimulant-L@ 625 ml/ha (T-14) resulted in maximum accumulation of dry matter @ 151g/m1 at harvest in comparison to recommended NPK, while it remained at par with nutrient management practice involving application of FYM@ 5t/ha+NPK-G@200kg/ha + NPK-bio-fertilizer and foliar spray of NPK-P @ 1% along with bio-stimulant-L@ 625 ml/ha (T-13) and FYM @5t/ha +NPK 200kg/ha + NPK-bio-fertilizer + Urea@ 20 kg/ha each as basal &40 DAS + Bio-stimulant-L @ 625ml/ha (T-12) upto 90 DAS and at harvest stages. Thus, the wheat crop grown with application of FYM@ 5t/ha+NPK-G@200kg/ha + NPK-bio-fertilizer + Urea @ 20kg/ha and foliar spray of NPK-P @ 1% along with bio-stimulant-L@ 625 ml/ha had attained better growth (plant height, dry matter accumulation, LAI,LAD,CGR,RGR and NAR. Significantly improved the protein content and protein yield.

Measurement of Intensity and Duration of Seed Dormancy in Different Rice Varieties by Probit Analysis

Paper ID- AMA-25-01-2022-11058

The purpose of this study was to look into the nature of seed dormancy variation in distinct maturity groups, such as early, medium, and late duration varieties. During kharif 2017, the field experiment was conducted with 54 rice varieties which were released by the Odisha University of Agriculture and Technology (O.U.A.T), Bhubaneswar and the National Rice Research Institute (N.R.R.I), Cuttack. The number of days required from the day of harvest to achieve 50 percent (DG50) and 80 percent (DG80) germination, as determined by probit analysis, which was used to evaluate the duration of dormancy. In seed biology, probit analysis is used to describe how seed germination progresses over time in response to environmental conditions (e.g. temperature, season etc). The DG50 and DG80 of the varieties ranged from 1 to 60 days and 4 to 79 days, respectively. The variety Khandagiri had the minimum dormancy period of 4 days, while the varieties CR Dhan 506 and CR Dhan 508 had the maximum of 79 days. The percentage of non-germinated seeds on harvest day (NGH0) and 7 days following harvest (NGH7) were used to determine the intensity of dormancy. The NGH0 and NGH7 ranged from 0.67% to 100% and 49.34% to 99%, respectively. Varietal variations in dormancy duration and intensity were indicated in these ranges. The majority of early varieties had a short dormancy period with low intensity, whereas the majority of mid to late varieties had a long dormancy period with high intensity. Dormancy duration and intensity had a strong positive relationship, and both had a strong positive relationship with days to flowering and days to maturity. Several late varieties were observed to have the highest seed dormancy, suggesting that they could be utilised as donors for transferring dormancy to other early varieties to avoid yield losses caused by viviparous germination.

Factors responsible for restraining stimulatory (Stand-Up) phase and strategic model to strengthen entrepreneurship-Study in context of food processing in rural Haryana

Paper ID- AMA-25-01-2022-11056

The core objective of present article is to identify the restraining factors affects the stand-up phase of food processing entrepreneurship and on the basis of outcomes reflected an integrated strategic model developed to strengthen the stimulation in entrepreneurship. For this purpose, 160 entrepreneurs engaged in Micro, small and medium units were selected from four industrially sound districts of Haryana. As being prominent agrarian state in India, food processing entrepreneurship was considerd the most favourable venture to stand-up. Data was collected personally through interview schedule. Analysis was done to understand the severity of percieved factors based on weighted mean score obtained and ranked them accordingly. Unhealthy economic situation in rural areas; heavy government taxes and poor implementation of schemes; ambiguity in selection of product were identified as highly serious factors whereas technically unsound, low awareness political unwill and untrained youth were few serious factors responsible for restraining entery to food processing entrepreneurship. The seriousness of the factors was based on computed Z score. On the basis of estimated outcomes, expert opinion and reviewed literature, a strategic model has framed to ensure the integrated efforts of all stakeholders associated with the development of entrepreneurship in the state.
