Assessment of poor quality irrigation water under different cropping systems in arid and semi-arid region, India.
The study was conducted to assessment of poor quality irrigation water under different cropping systems in arid and semi-arid region, India. The quality of irrigation was high SAR saline (EC= 6.1 dS m-1, SAR=10.6 mmol l−11/2) in sugarcane and rice-wheat, and marginally saline (EC= 2.7-3.8 dS m-1; SAR = 5.3-7.5 mmol l−11/2) in guar-wheat, and cotton wheat cropping systems. The SOC ranged from 3.52 to 8.98 g kg-1 under different cropping systems. Among the different cropping systems, sugarcane (8.98 g kg-1) cropping system possessed higher SOC content followed by rice-wheat (6.49 g kg-1), guar-wheat (4.99 g kg-1), moth bean-chickpea (4.93 g kg-1), cotton-wheat (3.85 g kg-1) groundnut-wheat (3.52 g kg-1). Saline water is widely used as an alternative water resource for agriculture production to overcome the freshwater shortage in arid and semiarid regions. But long-term using of the saline water for irrigation would negatively affect soil properties and crop production. the salinity and high SAR of the irrigation water should be properly managed to reduce the risks.
Effect of Dairy & Agricultural based ingredients and different fat levels of milk on Technology optimization and Quality Characterization of Chhana Podo
Chhana podo is a baked traditional Indian dairy product having nutritional benefits consumed widely in Orissa, West Bengal, and in other parts of the country. It is made from chhana, sugar semolina and often garnished with nuts, cloves & cardamom. The objective of the present study was to optimize the dairy & agricultural based ingredients, process parameters for the preparation of Chhana podo and its quality characteristics. The different fat levels of mixed milk (3%, 4.5% and 6%) were tried for preparation of chhana and the same was used for chhana podo preparation. The chhana prepared from mixed milk with 4.5% fat and 8.5% SNF was used for chhana podo preparation having more sensory acceptability than others. Nine-point hedonic scale was used for sensory evaluation of chhana podo. The chhana podo prepared was analyzed for the Physicochemical, textural, and microbiological attributes showed a good stability along with health benefits and high commercial value.
Effect of stabilization methods on bioactive components and stability indicators of wheat bran
The present investigation was undertaken with the objective to determine the best stabilization method which would safely preserve the wheat bran. For the stabilization of wheat bran, different methods (microwave heating (2450 MHz for 3 minutes), hot air oven (120℃ for 10 minutes), autoclave (121℃ at 15 psi), roasting (190℃ for 10 minutes) and chemical (ethanol 95%) were used and their effect on bioactive components and stability indicators were studied. The results showed significant increase in water activity from 0.542 to 0.607, moisture content from 7.19 to 7.88 %, free fatty acid (4.88 to 7.08 % as oleic acid), peroxide value (3.22 to 11.25 meq/Kg) during 90 days of storage. Among stabilization methods, the total phenolic content and antioxidant activity varied from 168.38 to 356.70 mg GAE/100g and 38.31 to 56.56%, respectively. Considering the role of water activity, moisture, free fatty acid, peroxide value and total microbial count in storage stability, microwave stabilization was found to be the most effective stabilization methods, followed by hot air oven and autoclave methods. After 90 days of storage, stabilized wheat bran samples were found to be shelf stable.
Effect of abiotic factors on the incidence of major sucking insect pests and their natural enemies associated with cluster bean, Cyamopsis tetragonoloba (Linn.) Taub. in Semi-Arid Region of Rajasthan
A field experiment was conducted at Agronomy Farm, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner to study the effect of abiotic factors on the incidence of major sucking insect pests and their natural enemies associated with cluster bean, Cyamopsis tetragonoloba (Linn.) Taub. during kharif season 2015 and 2016. The invasion of major sucking insect pests, jassid, Empoasca motti Pruthi; whitefly, Bemisia tabaci (Genn) and aphid, Aphis craccivora Koch commenced in the second week of August (33rd standard meteorological week, SMW) during 2015 as well as 2016 and reached at their peak in the first and second week of September i.e., 37th and 38th SMW. The population of jassid at peak period was 14.80 &15.50 and that of whitefly was 15.85 & 17.20 per 3 leaves during 2015 and 2016 respectively. The population of aphid reached at the peak in first week of September (36th SMW) and it was 7.80 and 6.85 per 3 leaves in the respective years. There was significant negative correlation of the population of jassid (r=-0.65*) and whitefly (r= -0.63*) with relative humidity during 2015. The correlation of the population of aphid (r=0.55*) with relative humidity was significantly positive in 2016. The correlation of the population of jassid (r= 0.47*, 0.63*) and whitefly (r= 0.52*, 0.72*) with maximum temperature was significantly positive in 2015 and 2016, respectively. The correlation of the population of aphid (r=0.55*, 0.52*) with minimum temperature was significantly positive in 2015 and 2016, respectively. The population of Coccinella septempunctata L. had significant positive correlation with the population of jassid (r= 0.89*, 0.95**), whitefly (r= 0.78*, 0.96**) and aphid (r= 0.55*, 0.56*) during both the years. The population of Chrysoperla carnea showed significant positive correlation with the population of jassid (r= 0.66*, 0.85*) and whitefly (r= 0.53*, 0.91**) but non-significant with aphid C. carnea during both the years.
Genetic diversity through D2 and cluster analysis for structural and economic traits in yardlong bean (Vigna unguiculata var sesquipedalis L.) under rainfed semi-arid conditions of Gujarat
The experiment was carried out at Central Horticultural Experiment Station, ICAR- CIAH Godhra, Gujarat. The genetic diversity was assessed to seventy genotypes of yardlong bean for three consecutive growing seasons during 2020, 2021 and 2022 for nine quantitative traits viz., plant height, number of branches per plant number of pods per plant, pod length, pod girth, pod weight, Days to first flower, days to fist harvest and pod yield per plant. The maximum inter cluster D2 value was observed between cluster I and cluster IV (54.85) followed by cluster II and cluster IV (51.83) which exhibits the wider genetic diversity which showed the wider genetic diversity among the genotypes of these clusters. The contribution of individual character to genetic divergence mainly comes from the traits like pod length (30.35%), pod weight (21.74%), number of pods per plant (19.92%), days to first flowering (15.82%). The various patterns of clusters shows the valuable traits for attaining high pod yield was present in cluster IV followed by cluster V. The cluster IV having higher mean values with respect to plant height, number of branches per plant, pods per plant and pod yield per plant. Whereas, the cluster V having higher mean values for pod length, pod girth and pod weight. The cluster II having higher mean values for earliness like days to first flowering and days to first harvest. Thus, more weightage should be given to the cluster IV and cluster V for yield and yield attributes and clusters II for earliness for parental selection and development of variety in future breeding programme of yardlong bean.
