A field experiment was carried out during the summer seasons of 2020 and 2021 at Jaguli Instructional Farm, BCKV, Nadia (West Bengal), in the Gangetic alluvial soil, to assess the effect of varieties and micronutrient foliar spray on growth parameters, yield components, yield and economics of mungbean. Results revealed that different varieties significantly promoted growth parameters and variety Meha was found to be superior. Growth parameters was significantly higher under molybdenum foliar spray over other micronutrients foliar spray. The maximum number of pods per plant, pod length, seeds per pod and test weight were found in plants receiving sodium molybdenum foliar spray at 0.05%. Maximum seed yield and stover yield were also recorded in the same treatment where 0.05% sodium molybdenum spraying was done at pre flowering and pod development stage. Variety showed significant variation in pods per plant, pod length, seeds per pod and test weight and were maximum in variety Meha. Both seed and stover yield were highest in case of variety Meha over others. The gross returns, net returns and benefit: cost ratio were maximum in Meha variety with foliar application of sodium molybdenum. Hence, variety Meha with foliar spray of molybdenum could be more effective in augmenting mungbean growth, yield and economics in the Gangetic plains of West Bengal in the summer season.
2020 年和 2021 年夏季，在西孟加拉邦纳迪亚 BCKV 的 Jaguli 教学农场，在恒河冲积土壤中进行了一项田间试验，以评估品种和微量营养元素叶面喷施对绿豆生长参数、产量成分、产量和经济效益的影响。结果表明，不同品种对生长参数有明显的促进作用，其中以品种 Meha 为优。钼叶面喷施的生长参数明显高于其他微量营养元素叶面喷施的生长参数。钼钠叶面喷施浓度为 0.05% 的植株每株结荚数、荚长、每荚种子数和试验重量均最大。在相同的处理中，在开花前和豆荚发育阶段喷施 0.05% 的钼钠，种子产量和秸秆产量也最高。各品种在单株豆荚数、豆荚长度、每荚种子数和试验重量上都有明显差异，其中以品种 Meha 的差异最大。与其他品种相比，Meha 品种的种子和秸秆产量最高。在叶面喷施钼钠的情况下，Meha 品种的总收益、净收益和效益成本比都是最高的。因此，在西孟加拉邦恒河平原的夏季，叶面喷施钼的品种 Meha 能更有效地提高绿豆的生长、产量和经济效益。

In majority of the area of Dang district of Gujarat, chickpea is grown under rainfed condition with neither improved varieties nor with recommended practices. The Krishi Vigyan Kendra, Navsari Agricultural University, Dang has organized 323 numbers of FLDs. This programme is with the objective to demonstrate the improved variety of chickpea (GG 5) for production potential. The demonstrated variety GG 5 performed better in all years compare to farmer’s variety (2018-19 to 2020-21). In the FLDs, the results revealed that seed yield (1102 kg/ha) of improved technology was higher as compared to farmers’ practice (825 kg/ha). Higher gross returns, net returns and benefit cost ratio were also recorded in FLDs plots as compared to farmer’s practice. The average technology gap, extension gap and technology index were calculated as 1398 kg/ha, 227 kg/ha and 55.93 per cent, respectively. Every year, extension gap was lower than technology gap indicating the need to educate farmers in adoption of improved technologies. Thus, it is suggested that location-specific approaches would be needed to bridge the productivity gap of chickpea crop in the region.

The study was conducted on HC 3 variety of chickpea to optimize the seed rate for bold seeded varieties during rabi 2022-23. The results revealed that there was a decrease in plant stand establishment, days to flowering, and plant height as the seed rate is reduced from 120 kg to 72 kg/ha. However, the seed yield per plant increased when the seed rate is reduced. The highest seed yield of 2010 kg/ha was recorded in seed rate of 84 kg/ha, but it decreased to 1727 kg/ha in seed rate of 72 kg/ha. Graded seed yield was recorded as the highest with 84 kg/ha (1772 kg/ha) compared to 72 kg/ha (1541 kg/ha). In terms of economic returns, the net monetary return per hectare was highest with a seed rate of 84 kg/ha (Rs. 2,30,098/-) compared to 120 kg/ha (Rs. 1,70,010/-) with benefit-cost ratio 4.03 and 2.85, respectively. It is concluded from the study that optimal seed rate for achieving maximum seed yield and improved seed quality in bold-seeded variety of chickpea is 84 kg/ha.

A field experiment was conducted during the kharif season of 2019 at the Research Farm, School of Agriculture, ITM University, Gwalior (Madhya Pradesh) to evaluate the effect of phosphorus and sulphur levels on productivity and profitability of blackgram. The experiment was conducted in a randomized block design with four phosphorus levels viz., 0, 20, 40 and 60 kg P/ha, along with three sulphur levels, viz., 10, 20 and 30 kg S/ha, which were replicated thrice. Results revealed that among the P levels, the application of 60 kg P/ha recorded significantly higher number of pods/plant (25.9), number of seeds per pod (5.4), test weight (37.30 g), seed yield/plant (8.26 g), seed yield (1412 kg/ha), stover yield (3542 kg/ha), and biological yield (4954 kg/ha). While among the sulphur levels, application of 30 kg S/ha recorded significantly higher number of pods/plant (23.6), number of seeds/pod (5.1), test weight (36.33 g), seed yield/plant (7.84 g), seed yield (1255 kg/ha), Stover yield (3185 kg/ha), and biological yield (4441 kg/ha). Combined application of 60 kg P/ha and 30 kg S/ha produced significantly highest net returns and benefit-cost ratio. Thus, application of 60 kg P and 30 kg S/ha was found to be the more promising treatment for enhancing the yield in blackgram.

Chickpea is the dominant rabi pulse crop in India, accounting for 50% (13.5 mt) of the nation’s pulse production. This nutrient-dense and cost-effective legume provides a rich source of energy, protein, minerals, vitamins, and dietary fibre. Beyond its basic nutritional value, chickpea harbor a diverse array of non-nutritive phytochemicals, including oligosaccharides, saponins, tannins, polyphenols, flavonoids, and enzyme inhibitors, holding promising potential for antioxidant, anti-inflammatory, anti-diabetic, anti-obesity, anti cancer, prebiotic, and cholesterol-lowering effects. Recent advancements in genome sequencing have unlocked the chickpea’s complete genetic blueprint and empowered cutting-edge breeding methods like QTL analysis, GWAS, and genomic selection to effectively pinpoint and target beneficial genomic regions governing key nutritional traits. These findings help germplasm enhancement, nutritional enrichment and optimization of bioactive components to meet the food security of nations. This chapter reviews the current state of knowledge regarding chickpea’s nutritional profile, highlighting past breeding achievements and future prospects for enriching its nutritive value.

A study on evaluation of certain new insecticides against pod borer complex in pigeonpea was conducted at Regional Agricultural Research Station, Warangal for three consecutive years from Kharif 2019-20 to Kharif 2021 22 in medium maturity pigeonpea cultivar ‘Rudreswara’ (WRG-65). Seven treatments including untreated control were evaluated for their relative efficacy towards suppression of pod borer larval population and reduction of percent pod damage. The insecticide treatments along with untreated control were applied two times during the crop season viz., 50% flowering and pod formation stage. The results revealed that chlorantraniliprole 18.5 SC @ 0.3 ml/L followed by emamectin benzoate 5 SG proved significantly superior against gram pod borer (Helicoverpa armigera) and spotted pod borer (Maruca vitrata) with highest mean percent larval reduction and cumulative least percent pod damage (10.8 and 14.7%, respectively) over control. Further, chlorantraniliprole 18.5 SC followed by emamectin benzoate 5 SG @ 0.4 g/l recorded higher grain yields and best ICBR ratio (1:4.6; 1:4.5). Thus, the effective chemicals observed in the study could be used as basis for selection of label recommended insecticides for successful management of pod borers in pigeonpea.

The time taken from sowing to flowering in pigeonpea is positively associated to its photoperiod responses; and it is expressed in terms of delay in flowering when exposed to long photoperiods. The late maturing genotypes, without exception, are photo-sensitive with critical daylength of around 11 h. The early f lowering types, on the other hand, are invariably photo-insensitive. The past research on this subject has shown that the photo-insensitivity in pigeonpea was controlled by 2-3 simply inherited recessive genes. The present study was designed to understand dominance relationships among photo-sensitive and photo-insensitive alleles in six diverse crosses. It involved two photo insensitive (Prabhat and Pant A3) and three photo-sensitive (Code 14, ICP 7065, T17) genotypes. Under long photoperiods, the three Prabhat hybrids, on average, flowered in 190.8 days, while the Pant A3 hybrids took only 82.1 days to flower. It was concluded that the two photo-insensitive genotypes carried different sets of genes for this trait. In Prabhat the photo-insensitivity was recessive in nature, while in Pant A3 it was controlled by partial dominant genes. This is the first report in pigeonpea where a photo-insensitive genotype with partial dominant genes has been identified.

Conservation Agriculture (CA) has emerged as a pivotal paradigm in modern agriculture, emphasizing sustainable practices to enhance crop productivity while preserving soil health and natural resources. Conservation agriculture relies on three key principles: including minimum soil disturbances, permanent soil covers with crop residue and promoting crop/species diversification. Pulses possess unique attributes, such as biological nitrogen fixation, leaf litter fall, nutrient-enriched crop residues, and a deep root system with enhanced rhizospheric activities, which make them conducive to CA principles. In the agriculture systems of southern Asia, the continuous practice of conventional input-intensive cereal-dominated production has largely contributed to soil degradation, depletion of underground water resources, and reduced land and water productivity, ultimately jeopardizing sustainable food production. Given this, researchers emphasize the pivotal role of crop diversification including pulses in the system in order to conserve natural resources, foster soil health, and sustain crop productivity. Experimental findings from diverse agro-ecologies provide evidence that the integration of pulses in CA not only contributes to enhanced agricultural sustainability but also holds the potential to address food security and nutrition challenges in an era marked by climate uncertainties and environmental degradation. Given the growing significance of pulses in CA, there is a pressing need for more systematic studies across diverse agro-regions to maximize the benefits of CA. This article highlights the important role of pulses in CA, focusing on its potential benefits pertaining to sustainable crop production, resource conservation and soil health
