ThesisItem Open Access INFLUENCE OF ZINC AND BORON ON WHEAT PRODUCTIVITY AND POTASSIUM USE EFFICIENCY IN AN ACID ALFISOL(CSHHPKV Palampur, 2012-12-01) NEHA; Sharma, R.P.The present investigation was carried out at experimental farm of Department of Soil Science, College of Agriculture, CSK HPKV, Palampur with sixteen treatments consisting of four levels of K (0, 50,100 and150% of recommended dose), two levels of Zn (0 and 10 kg ha-1 ) and two levels of B (0 and 1 kg ha-1 ) in factorial randomized block design. Application of K @ 50, 100 and 150 per cent of recommended dose increased plant height, dry matter accumulation, total and effective tillers per metre row length, grains per ear and test weight significantly. Similarly, application of Zn (10 kg ha-1 ) and B(1 kg ha-1 ) influenced these growth and yield attributes of wheat significantly. Highest grain (42.52q ha-1 ) and straw (66.80q ha-1 ) yield of wheat was recorded under 150 per cent of recommended dose of K. Application of 150 percent of recommended dose of K increased grain and straw yield by 43.7 and 46.9 per cent over no K, respectively. Application of Zn (10 kg ha-1 ) increased grain and straw yield by 10.9 and 9.8 per cent over no Zn, respectively. The increase in grain and straw yield with the application of B (1 kg ha-1 ) was 5.6 and 6.3 per cent, respectively. Application of K increased N, P, K, Mn, Fe, Cu and B contents significantly at maximum tillering and harvesting. Application of Zn increased Zn and B contents significantly at both the stages but the contents of Fe, Mn and Cu decreased. However, B increased the contents of Zn and B only at maximum tillering stage and Zn, Mn and B at harvesting (grain and straw). Almost similar effects of K, Zn and B application on total nutrient uptake were observed. Application of Zn increased partial factor productivity, physiological efficiency, agronomic efficiency and apparent recovery. B application increased partial factor productivity and apparent recovery only. Application of K, Zn and B increased available K, DTPA extractable Zn and available B content significantly, respectively.ThesisItem Open Access Effect of phosphorus solubilizing bacteria on economy of phosphorus in soyabean (glycine max L.)(CSKHPKV, Palampur, 2012) Rana, Manisha; Pathania, PawanThesisItem Open Access Effect of sowing dates and initial cutting time on forage yield and seed production of oat in mid hills(CSKHPKV, Palampur, 2012) Singh, Prabhjot; Sharma, V.K.ThesisItem Open Access Biochemical evaluation of adzuki bean (vigna angularis willd. ohwi and ohashi)genotypes(CSKHPKV, Palampur, 2012) Sharma, Shivani; Singh, NageswerThesisItem Open Access Assessment of nutritional status and cognitive development of selected pre school children of district Kangra(CSKHPKV, Palampur, 2012) Verma, Sakshi; Sood, SangitaThesisItem Open Access Performance of maize based intercropping system under organic conditions(CSKHPKV, Palampur, 2012) Kaushal, Shilpa; Kumar, RameshwarThesisItem Open Access Molecular characterization of a major begomovirus infecting pulse crops in Himachal Pradesh(CSKHPKV, Palampur, 2012) Sharma, Shivani; Singh, NageswerThesisItem Open Access Persistence studies of pretilachlor and its biochemical effects in transplanted rice(CSKHPKV, Palampur, 2012) Reetu; Sharma, NeelamThesisItem Open Access Biochemical evaluation of potato as influenced by metribuzin(CSKHPKV, Palampur, 2012) Suman Kumari; Sharma, Neelam
