    Integrated pest management of various insect-pests infesting Capsicum under protected cultivation and chilli in open condition
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2014-06) Pankaj Kumar; Srivastava, R.M.
    During present investigation different acaricide formulation, botanicals, and insecticides were evaluated against mites and sucking pest, infesting capsicum and chilli crops grown under polyhouse condition and open field condition respectively. Present study was a documentation of insect fauna associated with capsicum crop grown under polyhouse condition and chilli crop grown under agro-climatic condition of tarai region of Uttarakhand. Evaluation of biopesticide, botanicals and newer pesticides against insect pests in capsicum grown under protected condition indicated that incidence of aphid, thrips, mites, whitefly and bihar hairy caterpillar commenced on crop around 25-30 days after transplanting. It then gradually increased attaining peak during the period of December and January. Mealy bug incidence which was seen in low levels initially but attained peak during February month and then declined. It was noticed with reference to crop damage and significantly higher fruit yield was recorded in Chemical intensive which was superior to biopesticide and botanicals proved to be the best treatment as realized by the highest net returns as against biopesticide and botanicals. Maximum yield of 21433.3kg/ha was obtained in capsicum crop grown under protected condition treated with Thiamethoxam25%WG and minimum 13382.0kg/ha in neem oil. In chilli crop grown in open field condition observation of various insect pests indicated that whitefly, mite, thrips, pod borer (helicoverpa armigera), red cotton bug, cut worm and lady bird beetle occurred on crop during the April to June month and attaining peak with varied densities. In chilly crop grown in open condition significantly higher fruit yield were recorded in newer systemic insecticide/ acaricide provided considerable pest management and marketable yield. Maximum yield of 527.75 kg/ha was obtained in chilli crop grown in open condition treated with Propargite 57%EC and minimum 238kg/ha in NC-512 dose-150ml/ha in single picking of fruits.

    An economic analysis of kharif rice cultivation in Udham Singh Nagar district of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-07) Pankaj Kumar; Singhal, A.K.
    An attempt has been made in the study to examine the economics of Kharif rice cultivation in Udham singh nagar district of Uttarakhand. The primary data required for the study obtained from a total of 60 sample farmers drawn through simple random sampling which comprised of 29 marginal farmers, 17 small farmers and 14 large farmers. Cost of cultivation was computed using CACP cost concept and the resource use efficiency in rice cultivation was examined through Cobb-Douglass production function and MVP analysis. The per hectare total cost of cultivation for overall farms (cost C3) was found to be Rs. 39841.27 and total cost were highest on marginal farms i.e. Rs.43327.56 followed by small farms Rs.41608.17 and large farms Rs.38594.01 respectively. Average rice yield per hectare for overall farms was noticed at 46.98 qt/ha in case of large farmers 47.62 qt/ha which was followed by small farmers (46.02 qt/ha) and marginal farmers (44.83 qt/ha). The gross return per hectare for overall per hectare farm basis was Rs. 101059.20 and for marginal, small, land large were Rs. 35305.53, Rs.91055.52 and Rs.248152.40 respectively. The MVP analysis had shown that the resources such as fertilizers human labour and machine labour were exerted significant effect on kharif rice yield and also plant protection chemicals were found to be significant influence on rice yield. It was found that the marginal value products (MVPs) of the aforementioned resources exceeded their marginal input costs (MICs) indicating underutilization of resources. Hence, the rice yield could be increased by increasing the level of these resources. Major production constraints encountered in crop management practices, lack of skilled labourers, labour shortage, occurrence of weeds, pest and disease incidence and non-availability of credit. Some other constraints related to production aspects were low price for output and the crop failure also noticed.

    Studies on soil and foliar application of macro and micronutrients on yield and quality of mango (Mangifera indica L.) cv. Dashehari
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-05) Pankaj Kumar
    The present investigation was carried out at Horticulture Research Centre, Pattharchatta, G. B. Pant University of Agriculture and Technology, Pantnagar, district- Udham Singh Nagar, Uttarakhand during the year 2015-16. The experiment was laid out in RBD (Randomized Block Design) with 10 treatments and 3 replications. The results showed that the foliar application of macro and micronutrients exhibited improvement in fruit set, fruit yield, quality and nutrient status of soil and leaf. The investigation has shown that the application of RDF (1000 g N : 750 g P : 1000 g K) + NPK: 20:20:20 @ 1% (2 spray: first-15 days and second- 45 days after fruit set) + foliar spray of ZnSO4 @ 0.4% + Boric acid @ 0.2% + CuSO4 @ 0.2% (2 spray at just before flowering and marble stage) was found very effective for increasing the number of fruit set per panicle at marble stage (3.29), yield plant-1 890(228.24 kg), yield ha-1 (22.82 tonnes), per cent increase in yield (197.41 %), fruit weight (254.60 g), fruit length (10.86 cm) and fruit width (5.65 cm). The content of TSS (19.18 0B), total sugar (15.38 %), reducing sugar (3.94 %), non-reducing sugar (11.47 %), total carotenoids (12.08 mg 100 g-1 pulp) and ascorbic acid (48.47 mg 100 g-1 pulp) were also increased with this treatment. The results have shown that there was no consistency with respect to the effect of macro and micronutrients on soil and leaf nutrient status. Thus, it is concluded that the foliar application of NPK (20:20:20) @ 1 % + ZnSO4 @ 0.4 % + Boric acid @ 0.2 % + CuSO4 @ 0.2 % along with RDF (1000 g N : 750 g P : 1000 g K) may be adopted for improving fruit set, yield and quality of mango cv. Dashehari.
