Monocropping of rice in Brahmaputra valley of Asom region has led to deterioration of soil quality, a serious threat to its sustainability. Therefore on farm field experiments were conducted during 2005 to 2007 at four different sites, viz siteI (Nogaon), siteII (Hatichungi), siteIII (Chowkhatbharalua) and siteIV (Baruabari) in dominant soil series of Jorhat district of Assam to evaluate production potential, resource use efficiency and economics of four rice (Oryza sativa L.) based cropping systems (1.rice-fallow, 2. rice-potato, 3. rice -pea and 4. rice-mustard) at two levels of management, i e farmers practices (FP) and recommended package of practices (RPP). The cropping system productivity in terms of Rice Equivalent Yield (REY) of rice-potato cropping system (155.9 q/ha) in Aeric Fluvaquents with RPP was found economically significant followed by Fluvaquentic Endoaquepts(131.83 q/ha) and in Typic Endoaquepts, (109.6 q/ha), whereas rice- pea (102.2 q/ha) performed best and found economically viable in Typic Fluvaquents under flooded situation. Thus ricepotato system is productive, sustainable, resource-use efficient and remunerative cropping system followed by rice-pea and rice-mustard. Recommended package of practices performed better over farmers practice at all the sites for all cropping systems but specifically best results were recorded at Nogaon (Aeric Fluvaquents). Rice-potato cropping system gave highest gross returns in Aeric Fluvaquents (RS 103 097 ha) followed by Fluvaquentic Endoaquepts (RS 91 168 ha) and in Typic Endoaquepts with RPP (RS 72 975 ha) was found economically significant, whereas rice-pea gave highest gross return RS 95108/ha in Aeric Fluvaquents.

Fatigue index exhibits gender difference. This study was carried out to compare fatigue index of young, national level male and female field hockey players; and to explore physiological variables contributing to this difference. We measured running-based anaerobic sprint fatigue index and selected physiological parameters in male and female players matched for age, duration of training, diet, habitual physical activity, body weight and BMI. The male hockey players showed lower resistance to repeated sprints fatigue than the female players. Body weight, BMI and power variables positively correlated to fatigue index in both sexes; while lean body mass and age in males only, and body fat % in females only were found to be correlated to fatigue index. Difference in lean body mass, body fat %, strength and anaerobic power might be responsible for gender difference in intermittent & repeated sprints fatigue index observed in studied players. © 2015, Association of Physiologists and Pharmacologists of India.

Three post rainy season crops, viz. potato (Solanum tuberosum L.), pea (Pisum sativum L.) and mustard (Brassica juncea L.) were evaluated for their economic efficiency for two years (2005-06 to 2006-07) in four hydric rice growing soils under two management levels (farmers' practice and recommended package of practices) in upper Brahmaputra valley of Asom. The farm experimental results recorded tuber yield of 208 q/ha for potato, 9.48 q/ha of grain yield of mustard and 57.5 q/ha of green pod yield of peas under recommended doses with high benefit cost ratio of 2.44 for potato and 2.35 for mustard in Lahangaon series (coarse loamy Aeric Fluvaquents) as compared to farmer's practice (benefit cost ratio of 1.57 for potato to 1.71 for peas). The performance of potato and peas in rice fallows of Brahmaputra valley was evident in all soils under recommended practices in terms of benefit cost ratio, efficient uptake of NPK and yield.
