    Evaluation of new genotypes of vegetable pea (Pisum sativum L.) under tarai condition of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2014) Pandey, Pooja; Uniyal, S.P.
    In order to evaluate the performance of some of the new genotypes of vegetable pea under tarai condition of Uttarakhand, an investigation was carried out at Vegetable Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, during rabi season of 2012-13. The experiment was laid out in Randomized Complete Block Design with three replications and 26 treatments. During study, observations for plant height, days to first picking, pod length, pod diameter, pod weight, pod number per plant weight of pod, yield and T.S.S. were recorded. In addition, to assess the profitability of crop, net profit and Benefit-Cost ratio had also been worked out. The findings of present investigation revealed that the genotype PMR 51 was found superior over 5 checks viz., Arka Ajit, Arkel, E6, Pant Uphar and PSM 3 in respect to number of pods per plant, average pod weight, pod yield, net profit and B-C ratio. This genotype yielded 20.3 t pods from one hectare area with net profit of Rs. 81,661.00 and Benefit-Cost ratio of 2.00. The other genotypes which had given more pod yield and secured IInd & IIIrd position in net profit were PMR 61 and PMR 64. These genotypes recorded the net profit of Rs. 73,116.00 and Rs. 69,876.00, respectively. Based on the findings of present investigation, it could be concluded that under prevalent climatic conditions of Uttarakhand tarai region, the new genotype PMR 51 is the most promising in respect to number of pods per plant, pod diameter, average weight of green pod, weight of green ovules, green pod yield and finally net profit per unit area compared to 20 other new genotypes and 5 commercial cultivars. With respect to pod length and number of ovules, the genotype PM 81 was found the best. The other genotypes which showed more yield and profitability in the experiment were PMR 61 and PMR 64. Therefore all the above said genotypes, in future, could be taken in further breeding programmes in order to improve the qualitative and quantitative features of existing cultivars.

    Effect of nitrogen scheduling on growth, yield and quality of potato (Solanum tuberosum L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-07) Pandey, Pooja; Manoj Raghav
    The present investigation entitled “Effect of nitrogen scheduling on growth, yield and quality of potato (Solanum tuberosum L.)” was carried out during winter season of two consecutive years 2014-15 and 2015-16 at Vegetable Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, U. S. Nagar, Uttarakhand. The experiment was laid out in randomized block design with three replications having ten treatments in each. During the study, observations for growth characters, yield characters, quality attributes, nitrogen uptake, nitrogen use efficiency and apparent recovery were analyzed. Besides of this, to assess the profitability, cost of cultivation, net profit and benefit-cost ratio also were worked out. Two year investigation revealed that nitrogen scheduling significantly influenced the performance of potato crop. Among all the treatments, T9 (25% N of RDF as basal + 50% top dressing at 25 DAP + one foliar spray of urea @ 3% at 40 DAP) was proved best with respect to overall plant growth, tuber yield (36.62 t ha-1 and 31.53 t ha-1) and nitrogen apparent recovery (65.8 % and 62.5 %) and also registered maximum benefit-cost ratio (1.69 and 1.48) during both the years, respectively. It not only recorded 7.23 % higher yield over recommended treatment T1 (50% N of RDF as basal + 50% top dressing at 25 DAP) but also save 15 % nitrogen (25 kg ha-1). While, treatment T7 (50% N of RDF as basal + two foliar spray of urea @ 3% at 25 & 40 DAP) produced maximum quality tubers having dry matter (19.4 % and 19.3 %) and specific gravity (1.09 g/cm3) during both the years, respectively. Based on overall performance, it could be concluded that under prevalent climatic conditions of tarai region of Uttarakhand, 25% N of RDF as basal + 50% top dressing at 25 DAP + one foliar spray of urea @ 3% at 40 DAP can be recommended to get maximum potato tuber yield and higher net return whereas, 50% N of RDF as basal + two foliar spray of urea @ 3% at 25 & 40 DAP can be recommended to get quality tubers.
