Physicochemical, proximate and sensory evaluation of pearl millet and pigeon pea based nutrient dense mix

Severe acute malnutrition serves a high risk of mortality among children aged 6-59 months. At a community level anganwadi centers play a vital role in identifying malnutrition among children and enabling resources for growth and development. The aim of this study was to develop a nutrient dense mix using pearl millet and pigeon pea and evaluate its sensory, physicochemical and proximate properties. The nutrient dense mix was formulated using pearl millet and pigeon pea in several variations and the best accepted variation was selected through sensory evaluation and analyzed for its physiochemical and proximate composition. Variation 3 of the nutrient dense mix prepared by balancing pearl millet with rice had the highest acceptability in all sensory parameters. It had favorable physicochemical properties including water solubility index (20.1%), swelling power (3.7%) and low moisture content (3.7%). The proximate analysis revealed high energy (347.10±0.85 kcals), protein (14.28±0.04 g), fat (19.53±0.03) and calcium content (154.63±2.2 mg). The percentage adequacy of the nutrients from the nutrient dense mix showed that 31.27% of energy as per the estimated average requirements was met for 1-3 year olds and 25.5% for 4-6 year olds. The high sensory acceptability, low cost and good micro and macronutrient profile encourages further exploration for the product in curbing malnutrition.

Effect of Germination Time on the Properties of Flours from Red and Brown Varieties of Pigeon Pea (Cajanus cajan) Seeds

This study was designed to evaluate the effect of germination time on the proximate composition, functional and pasting properties of flours from red and brown varieties of pigeon pea seeds. The red and brown pigeon pea seeds were cleaned and germinated for 48, 72 and 96 h, respectively and processed into flours, while the flours produced from the ungerminated red and brown pigeon pea seeds served as control samples. The flours obtained were analyzed for proximate, functional and pasting properties using standard methods. The proximate composition of the samples showed that the flours produced from the red pigeon pea seeds had a range of 6.24 � 9.34% moisture, 10.37 � 20.95% crude protein, 1.21 � 1.12% fat, 2.32 � 3.32% ash, 3.14 � 4.23% crude fibre, 76.75-61.07% carbohydrate and 329.29 � 338.10KJ/100g energy, while that of the brown pigeon pea flours had a range of 6.44-9.77% moisture, 10.47-23.69% crude protein, 1.23-1.13% fat, 2.42-3.13% ash, 3.18-4.31% crude fibre, 76.26-57.99% carbohydrate and 358.18-336.83KJ/100g energy. The functional properties of the red pigeon pea flours revealed that the bulk density, water absorption capacity, oil absorption capacity, swelling capacity, gelation capacity and foam capacity ranged from 0.58-022 ml/g, 1.36-1.58 %, 1.40-1.61 %, 2.13-2.38 ml/g, 8.24-11.13 ml/g and 12.28-12.01 %, while that of the brown variety ranged from 0.63-0.36 ml/g, 1.47-1.69 %, 1.46-1.67 %, 1.67-2.46 ml/g, 8.88-11.41 ml/g and 13.33-13.06 %, respectively. The pasting properties of the red pigeon pea flours also showed that the peak, trough, breakdown, set back and final viscosities as well as the peak time and pasting temperature ranged from 3.10 � 5.556cP, 3.35 � 4.86cP, 2.65 � 4.57cP, 5.23 � 7.75cP, 8.82 -10.02cP, 6.79 � 7.34min and 69.79 � 92.710C, while that of the brown variety ranged from 3.59 � 6.21cP, 4.19 � 5.61cP, 3.77 � 5.23cP, 5.59 � 8.25cP, 9.60 � 11.08cP, 7.07 � 7.99min and 80.11 � 99.21oC, respectively. The study, however, revealed that the flours produced from both the red and brown pigeon pea seeds could be generally used as nutrient dense and functional ingredients in the preparation of a wide range of food products especially in Nigeria and other developing countries of the world where there is acute shortage of protein in order to ensure food and nutritional security.

Evaluation of different Starch Binders on physical quality of fish feed pellets / Avaliação de diferentes aglutinantes de amido na qualidade física de rações para peixes

Binders are the products that are used to bind, glue or hold the various feed ingredients together in order to maintain pellet integrity. For aqua-culturists, feed manufacturing is an expensive exercise due to the high cost of ingredients along with traditional artificial binders. The use of grain starches as aqua feed binders have advantages which include availability of that binder, nutritional contribution, and minimization of feed cost. A research trial was conducted to test physical properties such as palatability, water stability, dustiness, friability, settling velocity and floatation time of locally available starch i.e. wheat gluten, pea starch and guar gum and to assist their incorporation in on-farm aqua feed. Results revealed that among these three starch, the starch from pea source was proved superior over other two (wheat gluten and guar gum) as all physical quality parameters (dustiness, water stability and friability) revealed better performance of pea starch except pelletability in which guar gum performed best. Although not a single diet proved best in case of flotation time (Tf) and settling velocity (Vset) at varying lengths (6mm, 9mm and 12 mm). This finding indicates the significance of suitable binders for optimal water pollution and sustainable aquaculture. The use of these binders i.e. wheat gluten, pea starch and guar gum in fish feed pellets may also reduce dependence on synthetic binders and minimizes cost.

Aglutinantes são produtos usados para unir, colar ou manter juntos os vários ingredientes da ração, a fim de conservar a integridade do pellet. Para os aquicultores, a fabricação de ração é uma atividade difícil e cara por causa do alto preço dos aglutinantes artificiais tradicionais. O uso de amidos de grãos como aglutinantes de rações aquáticas tem vantagens que incluem acessibilidade, disponibilidade, contribuição nutricional e minimização do custo da ração. Um ensaio de pesquisa foi conduzido para testar propriedades físicas, como palatabilidade, estabilidade em água, pulverulência, friabilidade, velocidade de sedimentação e tempo de flutuação de amido disponível localmente, ou seja, glúten de trigo, amido de ervilha e goma de guar, e para auxiliar sua incorporação em rações aquáticas. Os resultados revelaram que, entre esses três amidos, o amido de ervilha se mostrou superior aos outros dois (glúten de trigo e goma de guar), pois todos os parâmetros de qualidade física (pulverulência, estabilidade da água e friabilidade) obtiveram melhor desempenho, exceto peletabilidade, em que a goma de guar se destacou. Nenhuma dieta se mostrou melhor no caso de tempo de flotação (Tf) e velocidade de sedimentação em comprimentos variados (6 mm, 9 mm e 12 mm). Essa descoberta indica a importância de aglutinantes adequados para a poluição ótima da água e a aquicultura sustentável. O uso desses aglutinantes, ou seja, glúten de trigo, amido de ervilha e goma de guar, em pellets de ração para peixes também pode reduzir a dependência de aglutinantes sintéticos e minimizar o custo.

Study of the Most Suitable Combination of Intercropping Systems of Indian Mustard (Brassica juncea L.) with Chickpea, Lentil, Linseed and Field Pea

Abstract: Intercropping system enhances crop productivity and profitability by growing different species together on the same piece of land in distinct row combinations. Hence, a field experiment was conducted to study the most suitable combination of mustard based intercropping with different crops at students’ instructional farm, C. S. Azad University of Agriculture & Technology, Kanpur (U.P.) during Rabi season 2021-22. The experiment was laid out in Randomized Block Design with nine treatment combinations viz., T1 Sole Mustard, T2 Mustard: Chickpea (1:1), T3 Mustard: Chickpea (2:1), T4 Mustard: Lentil (1:1), T5 Mustard: Lentil (2:1), T6 Mustard: Linseed (1:1), T7 Mustard: Linseed (2:1), T8 Mustard: Field Pea (1:1) and T9 Mustard: Field Pea (2:1) with replicated thrice. The results revealed that the significant impact of intercropping system on the growth, yield attributes, and overall yield of mustard when intercropped with chickpea, lentil, linseed, and pea. Plant population of intercrops showed non-significant differences, but at later stages, a 1:1 ratio consistently led to higher plant populations. Plant height, primary branches, and dry weight were generally higher in the 1:1 ratio compared to the 2:1 ratio in all intercrops. Yield attributes, including the number of pods or capsules and seeds per pod or capsule, favoured the 1:1 ratio. The highest yield was observed in the 1:1 ratio, contrasting with the minimum in the 2:1 ratio of mustard + intercrops. Overall, the 1:1 ratio demonstrated superior performance in terms of growth, yield attributes and yield, emphasizing the importance of intercrop ratio in optimizing crop growth and productivity.

Stability Analysis in Field Pea (Pisum sativum L.) Genotypes under Various Environmental Conditions

Present study was undertaken to estimate the G x E interactions and identify the stable genotypes for yield traits in field pea. A total of 43 field pea genotypes were evaluated in Randomized Complete Block Design (RCBD) in three replications along with three different dates of sowing at BSP Soybean Unit, Department of Genetics and Plant Breeding, College of Agriculture, JNKVV, Jabalpur during Rabi Season 2022-2023. The analysis of variance was applied on 16 different quantitative traits both individually and pooled under various environmental conditions. The stability analysis for seed yield per plant was assessed using Eberhart and Russell's model, revealing significant variations among different genotypes and environmental conditions. The mean squares attributed to both environments and genotype-environment interactions (E + G x E) indicated significant interactions between genotypes and environments. Further, partitioning of genotype-environment (linear) interactions was found to be highly significant for seed yield per plant. Genotypes Shikha, KPMR 485 and HFP 94-12 were found ideal and stable genotypes for seed yield per plant as that possessed mean value higher than general mean, regression coefficient near to unity (Bi=1) with minimum deviation from regression (S2di~0). Thus, identified stable genotypes can be utilized for different seasons and regions for obtaining the stable yield performance.

Hence, significantly highest dry matter plant-1, no. of pods plant-1, seed weight and seed yield plant-1 was observed in 25th SMW sowing; seed yield (417.7 kg ha-1), seed yield heat use efficiency (0.20 kg ha-1 0C day-1) was recorded highest in 27th SMW sowing and lowest in 25th SMW sowing. Significantly highest no. of pods plant-1, seed weight and seed yield plant-1, seed yield heat use efficiency, pheno thermal index was observed in BDN-711 variety and significantly lowest in BSMR-853 variety. The significantly highest total dry matter plant-1 was observed in BSMR-853 and lowest in BDN-711 variety. Significantly highest GDD, HTU and PTU required for completion of different phenophases were recorded in BSMR-736 variety and significantly lowest in BDN-711 variety. Weather indices viz., GDD, HTU, PTU, PTI showed non-significant correlation at all the phenophases with seed yield of pigeonpea. The yield prediction model based on thermal indices and seed yield heat use efficiency at floral bud initiation to 50 % flowering and at 50 % flowering to 50 % pod formation phenophases was found useful in assessing the crop yield one and half to one month in advance.

Impact of Technological Interventions on Pigeon Pea for Enhancing Income through Cluster Front Line Demonstrations

Aims: The area and production of pigeon pea in Bhadohi are still significantly lower than in other districts of other states. There is a significant yield gap between the potential output and the yield under current farming conditions. To study the impact of technological interventions on the pigeon pea crop for increasing income through Cluster Front Line Demonstrations was the goal of the current study.Place and Duration of Study: Cluster front line demonstrations on improved pigeon pea technologies were carried out by ICAR-IIVR-Krishi Vigyan Kendra, Bhadohi, at farmers' fields from 2015–16 to 2019–20.Methodology: A total of 155 pigeon pea cluster front line demonstrations on improved pigeon pea technologies covering a 45.70 hectare area were held in one hundred eighteen localities. Field days, training and group meetings were also organized to provide opportunities for other farmers to witness the benefits of demonstrated technologies. The output data were collected from CFLD plots as well as control plots (farmers practice) by random crop cutting method and analyzed using simple statistical tools such as per cent change in yield, cost of cultivation, net income, and benefit cost ratio etc. Results: In the experimental plots, the mean yield over five years was 15.44 q/ha, while it was only 11.21 q/ha in the control plots. Over the course of the five years of the study, the yield development varied, though on average, it was measured at 42.49 percent. When compared to the farmer's practice (28,463/ha), the average net return for the demonstration plots at the farmer's field over the investigation period was greater at 56,611/ha. Additionally, the demonstration plots' benefit-cost ratio was larger (2.32) than the farmer's practice's (1.69).Conclusion: From the aforementioned findings, it can be concluded that using modern technologies for pigeon pea cultivation may significantly close the extension and technology gap, increasing pigeon pea yield in the area. It requires collaborative extension efforts to enhance the adoption of location and crop specific technologies among the farmers to bridge these gaps.

Genetic Variability, Heritability and Genetic Advance Studies in Field Pea (Pisum sativum L.) for Yield and its Attributing Traits

An investigation was carried out with 48 genotypes of pea obtained through line x tester mating and were tested using a randomized block experimental design with three replications. The result showed a highly significant difference for all the 14 characters under study. The variability, heritability and genetic advance as percent mean were studied for all the characters. A high genotypic coefficient of variation was observed for the traits number of secondary branches, plant height, number of pods per plant, harvest index, nodules fresh weight and nodules dry weight. High heritability coupled with high genetic advance estimates was recorded for the number of secondary branches, plant height, pod length, number of seeds per pod, number of pods per plant, 100 seed weight, grain yield per plant, harvest index, nodules fresh weight and nodules dry weight indicating the role of additive gene action and selection for these traits could be reliable.

Effect of Organic Mulches on Yield, Water Productivity and Economy of Garden Pea Cultivars

Mulching techniques that are adaptive and extremely successful may be able to reduce the detrimental impacts of crop production and water stress on different varieties of peas in a climate change scenario. Field experiment was carried out in the Umroi region of Meghalaya during the rabi season (2020–2021) for this reason. This study used a split-plot design with three organic mulches as the main plot treatment and four pea types as the sub-plot treatments, which was replicated three times. The field trial showed that paddy straw mulch significantly outperformed both weed mulch and no mulch in terms of green pod yield, water productivity, and benefit cost ratio, with values of 89.33, 54.14 kg ha-1 mm-1, and 3.16, respectively.VM 12 greatly topped other cultivars in terms of green pod yield, water productivity, and benefit-cost ratio (BCR), with values of 89.78 kg ha-1, 54.41 kg ha-1 mm-1 and 3.33, respectively. The investigation showed that the best alternative agronomic strategy for achieving the maximum yield output of garden pea was paddy straw mulch, followed by weed mulch and un-mulch.
