Palam Lalima and Suvarna performed best when they were planted during first fortnight of April as compared to first fortnight of May. Significantly higher fresh rhizome yield (18.77 and 17.77 t/ha) net return (Rs 2,00,748 and 1,92,748/ha) and B C ratio (2.23 and 2.18) was recorded when turmeric was sown in first and second fortnight of April as compared to first fortnight of May. Higher net returns (Rs 3,39,393/ha) and B C ratio (3.09) was observed in Palam Lalima. Owing to better growth attributes higher rhizome yield /plant (236.78 g) mother, primary and secondary rhizome weight had assisted Palam Lalima to attain higher rhizome yield. Thus significantly superior growth attributes viz., plant height (50.2 cm); LAI (6.43) and number of leaves/plant (9.0) were recorded in Palam Lalima. Palampur, , Himachal Pradesh, Kangra, Dharamshala, Hotels in Palampur, palampurpanorama.com and yield attributes observed in IISR Alleppey Supreme and IISR Prathibha was due to sub optimal temperature prevailed in the experimental area. Among tested cultivars higher curcumin (4.73%) and oil content (6.7%) was recorded in IISR Alleppey Supreme and Suvarna respectively.
Among the turmeric cultivars Palam Lalima recorded highest fresh rhizome yield (25.10 t/ha) followed by Suvarna (18.02 t/ha) and found to be suitable for cultivation in mid hills of North West Himalayas. 50 per cent N through FYM to rice followed by 100 per cent NPK to wheat recorded highest net returns in rice-wheat cropping sequence while application of 100 per cent NPK through chemical fertilizers recorded highest benefit cost ratio. However Palampur, , Himachal Pradesh, Kangra, Dharamshala, Hotels in Palampur, palampurpanorama.com was recorded when turmeric was established by transplanting seedling as compared to conventional rhizome planting. Zero fertilization led to decline in the levels of all the forms of sulphur at both the depths as compared to the buffer plots while, application of sulphur containing fertilizers and organics increased all the sulphur fractions in soil compared to control. There was a significant increase in organic carbon, CEC and available phosphorus content, respectively, through integrated use of organics and inorganics for the last twenty years over its initial value while available N and K declined over the years in all the treatments. The continuous use of chemical fertilizers alone for twenty years brought out marked depletion in the pools of Zn and Cu compared to buffer plots while, integrated application of organics and chemical fertilizers recorded relatively higher content of pools of Zn and Cu over chemically treated plots.
Integrated use of inorganic fertilizers along with organics enhanced the productivity and NPK uptake by rice and wheat significantly. Besides, pH, organic carbon, CEC, available N, P, K and S and micronutrient cations were also determined in surface soil samples taken before rice (2010 and 2011) and wheat (2010-11 and 2011-12) using standard methods of analysis. Heat soluble S and organic S was found to play major role in supply of sulphur in rice and wheat, respectively. Abstract: newline ABSTRACT newlineThe present investigation was carried out to study the effect of integrated nutrient supply on transformation of sulphur, zinc and copper into various chemical pools in the on going long-term fertilizer experiment initiated during 1991 at Bhadiarkhar farm of College of Agriculture, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur in randomized block design with twelve treatments replicated four times. Palampur, , Himachal Pradesh, Kangra, Dharamshala, Hotels in Palampur, palampurpanorama.com , HPSEB, said efforts were on the way to restore the supply.
