    Effect of spacing on green pod yield of pea cultivars (Pisum sativum Linn.) in rainfed mid hills
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-07) Rawat, Devendra Singh; Uniyal, S.P.
    The present investigation was conducted during August, 2003 to November, 2003 at the Sub Research Station, Gaja, G.B. Pant University of Agriculture & Technology, Hill Campus, Ranichauri, Tehri Garhwal (Uttaranchal), to study the effect of spacing in green pod yield of vegetable pea cultivars. The experiment was laidout in a Factorial Randomized Block Design, having fifteen treatment combination with three replications. The plant spacing range was from 25x5 cm to 35x5 cm. During the course of investigation, plant emergence, plant height, number of primary branches, leaf area, fresh and dry weight of plant, root length, number and fresh weight of nodules per plant, number of pods per plant, pod length, green pod yield, total soluble solids, protein profile, linear correlation etc. were studied. Significant effect of spacing was observed on number of primary branches, leaf area at 45 DAS, fresh and dry weight of plant, number of nodules, green pods per plant, pod length and green pod yield. Except number of primary branches, leaf area, root length, TSS content, the varieties were differed significantly in respect of plant height, number of nodules, number of green pods/plant, pod shelling percentage and green pod yield. Among the five varieties selected for investigation, standard check „Arkel‟ was found the best with respect to pod length, number of pods per plant and green pod yield. In different spacing and varietal combinations, highest yield of green pods (79.80 q ha-1) was obtained in S1V5 („Arkel‟ was at planting distance of 25x5 cm). From economic point of view also, standard check „Arkel‟ had found to be the most profitable, having a net profit of Rs. 42,018.75/ha, under recommended package of practices followed by „Pusa Pragati‟. The B/C ratio was also same (2.33) in both the varieties. The total number of protein bands in the seed of five varieties during SDS-PAGE analysis were varied from 19 to 23. Based on the findings of the present investigation „Arkel‟ and „Pusa Pragati‟ are the most suitable varieties for the sowing in Rainy-Autumn season under the rainfed mid hill climatic conditions of Uttaranchal, it sown at a planting distance of 25x5 cm.

    Effect of organic matters on growth, yield and quality of potato (Solanum tuberosum L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-06) Arun Kumar; Singh, N.P.
    The present investigation entitled “Effect of Organic Matters on Growth, Yield and Quality of Potato (Solanum tuberosum L.)” was carried out at Seed Production Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, District-Udham Singh Nagar (Uttaranchal) during rabi season of 2002 - 2003. The experiment was laid out in Randomized Block Design with eleven treatments and four replications. The observations on growth characters were recorded at different growth stages, while yield and quality characters were recorded at harvesting. The data were analyzed for standard error of mean and critical difference (C.D.) at 5 % level of significance. Analysis of variance revealed significant differences for all the characters. Based on the findings of the present investigation, T5 treatment (FYM @ 40 t/ha) was found superior over other treatments. Maximum plant emergence, plant height, number of leaves, number of shoots per plant, maximum fresh weight and dry weight of potato tubers per plant, maximum average tuber yield of potato and chlorophyll content of fresh leaves were recorded with high dose of FYM (40 t/ha). But it was found that increasing fertility level with FYM resulted decrease in specific gravity and T.S.S. of fresh potatoes. It was found that higher dose of FYM (40 t/ha) resulted minimum incidence of late blight, aphid population and white fly population per plant.

    Effect of FYM and doses of NPK on growth, yield and quality characters of potato cultivars
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-06) Chauhan, Reshu; Manoj Raghav
    The investigation entitled “Effect of FYM and doses of NPK on growth, yield and quality characters of potato cultivars” was carried out to examine the response of FYM and NPK doses on growth, yield and quality characters of potato cultivars. Another aspect was to know the effect of treatments on economics of potato cultivation. The field experiment was conducted at Vegetable Research Centre, Pantnagar during autumn- winter season 2003 – 2004. The experiment was laid out in Factorial Randomized Block Design with three replications and eighteen treatment combinations. The observations of growth characters were recorded at different growth stages. While yield and yield attributes and quality characters were recorded at /after harvesting of the crop. The data were analysed for standard error of mean and critical difference at 5 per cent level of significance. Analysis of variance of treatment combination revealed significant differences for all the characters except plant height, number of haulms per plant, number of leaves per plant, tuber yield per plot (kg), total tuber yield (q/ha), average tuber weight (g) and tuber yield per plant (kg). Based on the findings of present investigation variety Kufri Sutlej with 120 : 75 : 90 Kg NPK/ha +10t FYM/ha was found superior for maximum tuber yield as compared to rest of the treatment followed by Kufri Badshah with 80 : 50 : 60 Kg NPK/ha + 10 t/ha FYM. But the later treatment gave maximum CB ratio, hence on the basis of study Kufri Sutlej with 120 : 75 : 90 Kg NPK /ha +10 t/ha FYM for getting maximum tuber yield and Kufri Badshah with 80 : 50 : 60 Kg NPK /ha +10 t/ha FYM can be recommended for getting maximum C.B ratio.

    Level of self–incompatibility and inbreeding depression in tropical cauliflower (Brassica oleracea L. var. botrytis)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-06) Damke, Sujata R.; Singh, B.P.
    The investigation entitled “Level of self-incompatibility and inbreeding depression in tropical cauliflower (Brassica oleracea L. var. botrytis)” was carried out with the following objectives : (i) To study seed set under different modes of pollination. (ii) To estimate self-incompatibility within cultivar. (iii) To study inbreeding depression in S1 over open and sib-pollinated progenies. The field experiment was conducted at Vegetable Research Centre, Pantnagar. The tropical cauliflower variety Pant Shubhra was subjected to open, bud and natural self pollination during autumn-winter 2002 – 2003. The progenies were evaluated during autumn-winter 2003 – 2004 in a Randomized Block Design with two replications. The ANOVA revealed significant differences between mean performance of open and bud pollinated progenies for all the characters. The mean performance of open pollinated progenies was 374.71 g net curd weight in comparison to 297.67 g in inbred progenies. Based on the findings of the present investigation, the average self-incompatibility was found tobe approximately 80 per cent in Pant Shubhra. The PS-74-I1 inbred line was found tobe the best line for most of the characters i.e. stalk length, number of leaves, leaf length, leaf width, equatorial diameter of curd, polar diameter of curd with minimum inbreeding depression. Inbred lines PS-89-I1 and PS-56-I1 were found tobe the best for early curd maturity and net curd weight respectively. From the above study, it was concluded that the inbred line PS-74-I1 was self-incompatible and proved tobe the best parental line showing minimum inbreeding depression for most of the characters.
