A field experiment was carried out at Research Farm of Department of Agronomy and Rice and Wheat Research Centre (RWRC) Malan, Himachal Pradesh, India to study the “Influence of cultivation practices and varieties on productivity and profitability of wheat-rice cropping system”. Four tillage methods viz., reduced tillage, zero tillage, conventional tillage, and natural farming were applied to three varieties each of rice (HPR 1156 (Sukara Dhan 1), HPR 2656 (Him Palam Dhan 1) and HPR 2795 (Him Palam Lal Dhan 1)) and wheat (HPW 349, HPW 368, and HS 562) during winter 2019-20 to rainy 2021. The experiment was conducted in split-plot design. The experimental results revealed that conventional tillage resulted in a higher system equivalent yield of 8.15 t ha-1 and 8.19 t ha-1 at Palampur, and 8.54 t ha-1 and 8.37 t ha-1 at Malan during both years whereas among varieties, V3 (HS 562 fb Him Palam Lal Dhan 1) varieties of rice and wheat, resulted in a higher system equivalent yield during both years and at both locations, respectively. Higher values of economic indicators were recorded in conventional tillage among cultivation practices while lower values of economic indicators were recorded in natural farming treatment during both the years and in both the crops. Among the varieties, V3 (HS 562 fb Him Palam Lal Dhan 1) varieties of wheat and rice recorded higher values of economic indicators in rice-wheat system at both locations and during both years. Conclusively, for higher system productivity and profitability from the wheat-rice system, conventional tillage along with V3 (HS 562 fb Him Palam Lal Dhan 1) varieties must be adopted.
The experiment was carried out at Department of Renewable Energy Engineering, College of Technology and Engineering, Maharana Pratap University of Agriculture and Technology, Udaipur to study drying of aloe vera gel (Aloe vera barbadensis miller) in solar cabinet dryer. In the present investigation, aloe vera dried in solar cabinet dryer and compared with open sun drying method. Results showed that moisture content, average drying rate in aloe vera gel as 98.45 per cent (wb) to 8.82 per cent (wb) and 1.47, 1.34 and 1.19 g/100g dm/ h to 3.96, 2.7 and 2 g/100g dm/ h in solar cabinet dryer and in open sun, respectively. The moisture diffusivity varied in the range of 1.59×109m²/s to 1.54×109 m2/s in open sun drying and 1.88×109 m2/s to 2.56×109 m2/s in solar cabinet drying of aloe vera samples. Among the twelve thin layer drying model, best-ranked model applicable to the variation of moisture ratio with drying time of aloe vera samples in open sun drying were two-term model whereas in cabinet drying was diffusion approach model.
Sorghum is the forth important crop among the world’s leading cereals. Millions of people in Asia and Africa depend on sorghum as the staple food. Seeds have to be stored, of course, because there is usually a period of time between harvest and planting. Good seed physical quality, germination and vigor is expected to happen with good storage. This study was undertaken to assess storage potential of various sorghum genotypes stored under ambient condition. Seeds of sorghum varieties viz., CO30, CO32, K12 and Paiyur 2, pre-released cultures viz., TNS661, TNS663, TNS676 and TNS680 and land races viz., Vaiyappamalai local, Thenkasi local, Edapadi local and Chithalathur were treated with Carbendazim@ 2g/kg of seed, packed in cloth bag, kept in storage and assessed at bimonthly intervals. During storage, a reduction in vigour and viability was observed both in control and treated seeds in all the genotypes, but reduction is lower in treated seeds. Viability percent was maintained above to the Indian Minimum Seed Certification Standards (IMSCS) (75 %) upto 8 months of storage and in some of the genotypes, it was started to decline below to the IMSCS from 10 months after storage. Among the genotypes, Edapadi local maintained higher germination of 75 and 77% in control and treated seeds, respectively up to 22 months after storage. Hence, from this study it was inferred that the genotypes, edapadi local treated with carbendazim @ 2 g / kg of seed can be stored under ambient condition upto 22 months after storage.
A field experiment was started from Kharif 2012 (establishment year) to 2015 at JNKVV, Jabalpur to evaluate the performance of lowland grasses regarding crop establishment, forage productivity and nutrient management. The treatments consisted of three types of grass, viz., para grass (Brachiaria mutica), humidicola grass (Brachiaria humidicola) and guinea grasses and four nutrient management practices, viz., M1- 100% NPK through inorganic fertilizers; M2- 50% NPK through inorganic fertilizers + FYM @ 5 t/ha; M3- FYM @ 5 t/ha and M4- Farmer practice (without nutrient) laid out in split plot design and replicated three times. The study on the effect of nutrient management on the productivity of perennial grasses under high moisture conditions revealed that the grass Brachiaria mutica grown with M1- 100% NPK (inorganic fertilizer) gave the highest green and dry fodder yield and net monetary returns fb by M2- 50% NPK through inorganic fertilizer + FYM @ 5 t/ha.
Tea has anecdotally been associated with stress relief, but this has seldom been tested scientifically. To investigate the effects of 6 weeks of black tea consumption, compared with matched placebo, on subjective, cardiovascular, cortisol and platelet responses to acute stress, in a parallel group double-blind randomised design. Seventy-five healthy nonsmoking men were withdrawn from tea, coffee and caffeinated beverages for a 4-week wash-out phase during which they drank four cups per day of a caffeinated placebo. A pretreatment laboratory test session was carried out, followed by either placebo (n = 38) or active tea treatment (n = 37) for 6 weeks, then, a final test session. Cardiovascular measures were obtained before, during and after two challenging behavioural tasks, while cortisol, platelet and subjective measures were assessed before and after tasks. The tasks induced substantial increases in blood pressure, heart rate and subjective stress ratings, but responses did not differ between tea and placebo treatments. Platelet activation (assessed using flow cytometry) was lower following tea than placebo treatment in both baseline and post-stress samples (P < 0.005). The active tea group also showed lower post-task cortisol levels compared with placebo (P = 0.032), and a relative increase in subjective relaxation during the post-task recovery period (P = 0.036). Compared with placebo, 6 weeks of tea consumption leads to lower post-stress cortisol and greater subjective relaxation, together with reduced platelet activation. Black tea may have health benefits in part by aiding stress recovery.
