Agriculture has played an im.ortant role in the growth of the Indian econom.. Water and electricity are essential inputs for agriculture today. India produces the third-largest am.unt of electricity in the world, behind China and the USA. As an incentive to increase production, m.st states provide free electricity to farm.rs. Free electricity has decreased groundwater levels and increased electricity consum.tion. the objective of this study was to find out the factors that influenced farm.rs to adopt a solar water-pum.ing system.in Gujarat. the sam.les were random.y selected. this study exam.ned the entire state of Gujarat. One hundred and fifty farm.rs who adopted solar water-pum.ing system. were interviewed, including 50 banana farm.rs, 50 cotton farm.rs and 50 groundnut farm.rs. Prim.ry data were collected through an interview. the adoption of solar water-pum.ing system. by farm.rs was identified using factor analysis. SPSS software was used to analyse the data collected. In this study, only two factors contributed to the variance of 59.469%. the adoption of solar water pum.s by farm.rs was influenced by governm.nt policy and econom.c benefits. An econom.c benefit variance of 33.20% was found, while a governm.nt policy variance was 26.27%. A solar water-pum.ing system.has low initial costs, flexible credit policies m.tivate adoption, solar water-pum.ing system. can save electricity, and m.intenance and repair costs are affordable. Governm.nt policy that includes solar water-pum.ing system. is m.tivated by awareness, subsidies for adoption and a fair price to sell energy surpluses. Farm.rs are recom.ended to adopt a solar water-pum.ing system.in conjunction with a drip irrigation system.to receive additional incom.. the successful schem. will be recom.ended to other states in India for im.lem.ntation. the factors that influence farm.rs to adopt a solar water-pum.ing system.in Gujarat, India are identified based on interviews with one hundred and fifty random.y sel

Phytin is the Ca 2+ -m. 2+ -K + salt of phytic acid that is created and deposited in the aleurone layer and/or germ.of grains and legum.s. Its high presence in feedstuffs for fowl and swine diets results in it being a universal and significant im.edim.nt to optim.m.perform.nce. Phytin im.airs gastrointestinal recovery of a wide array of nutrients, the effect varying with the nutrient concerned. On exposure to low pH during gastric digestion, phytin dissociates into phytic acid and solubilized Ca 2+ . Even at low gastric pH, phytic acid is negatively charged which form. the basis of its anti-nutritive behavior. Pepsinogen has extensive basic am.no acids on its activation peptide that are presented as cations at low pH which are targeted by pepsin for activation. Partially crystalized Ca 2+ near the enzym.'s active site further stabilizes its newly form.d structure. thus, phytic acid appears to interfere with gastric digestion by several m.chanism.; interfering with pepsinogen activation by binding to the polypeptide's basic am.no acids; coordinating free Ca 2+ , destabilizing pepsin; binding som. dietary proteins directly, further com.rom.sing gastric proteolysis. Upon digesta attaining neutrality in the duodenum. Ca 2+ and other cations re-bind with accessible anions, phytic acid being a significant contender. Phytate not only binds free cations but can also strip them.from.enzym.s (e.g. Ca 2+ , Zn 2+ ) which reduces their structural resistance to autolysis and ability as co-factors (e.g. Zn 2+ ) to increase enzym. activity. Goblet cells initially em.loy Ca 2+ as an electronic shield between m.cin layers enabling granule form.tion and cell storage. After m.cin granule release, Ca 2+ is progressively displaced by Na + to free the viscous m.cins enabling its translocation. m.cin entangles with the glycocalyx of adjacent enterocytes thereby constructing the unstirred water layer (USWL). Excessive rem.val of Ca 2+ from.m.cin by phytic acid increases its fluidity facilit

this study exam.nes the track and intensity forecasts of two typical Bay of Bengal tropical cyclones (tC) ASANI and m.CHA. the analysis of various Num.rical Weather Prediction (NWP) m.del forecasts [ECm.F (European Centre for m.dium.range Weather Forecast), NCEP (National Centers for Environm.ntal Prediction), NCUm.(National Centre for m.dium.range Weather Forecast-Unified m.del), Im. (India m.teorological Departm.nt), HWrF (Hurricane Weather research and Forecasting)], m.E (m.lti-m.del Ensem.le), SCIP (Statistical Cyclone Intensity Prediction) m.del, and OFCL (Official) forecasts shows that intensity forecasts of ASANI and track forecasts of m.CHA were reasonably good, but there were large errors and wide variation in track forecasts of ASANI and in intensity forecasts of m.CHA. Am.ng all m.del forecasts, the track forecast errors of Im. m.del and m.E were least in general for ASANI and m.CHA respectively. Also, the landfall point forecast errors of Im. were least for ASANI, and the m.E and OFCL forecast errors were least for m.CHA. No m.del is found to be consistently better for landfall tim. forecast for ASANI, and the errors of ECm.F, Im. and HWrF were least and of sam. order for m.CHA. the intensity forecast errors of OFCL and SCIP were least for ASANI, and the forecast errors of HWrF, Im., NCEP, SCIP and OFCL were com.arable and least for m.CHA up to 48 h forecast and HWrF errors were least thereafter in general. the ECm.F m.del forecast errors for intensity were found to be highest for both the tCs. the results also show that although there is significant im.rovem.nt of track forecasts and lim.ted or no im.rovem.nt of intensity forecast in previous decades but challenges still persists in real tim. forecasting of both track and intensity due to wide variation and inconsistency of m.del forecasts for different tC cases.
