    Genetic variability studies in pea (Pisum sativum L.) under sub tropical conditions of Himachal Pradesh
    (College of Horticulture and Forestry Neri, Hamirpur (H.P.), 2022-10-06) Kumari, Manisha; Sharma, Deepa
    The present investigation entitled “Genetic variability studies in pea (Pisum sativum L.) under sub tropical conditions of Himachal Pradesh” was carried out during Rabi season 2021-2022 at Experimental Research Farm, Department of Vegetable Science, College of Horticulture and Forestry, Neri, Hamirpur (H.P). Twenty eight genotypes including check variety Punjab-89 were evaluated in Randomized Complete Block Design with three replications to estimate the extent of variability, heritability, genetic advance, correlation and path coefficient analysis for yield and other horticultural traits. Analysis of variance revealed significant differences among all the genotypes with respect to the characters studied. The genotypes Pusa Pragati (3.23 kg, 54.67, 9.77 g, 4.74 cm), LC-P-1 (2.91 kg, 57.33, 8.46 g, 4.71 cm) and LC-P-2 (2.86 kg, 59.67, 8.78 g, 4.60 cm ) were recorded superior over the check Punjab-89 for pod yield per plot, days to first flower, pod weight and pod girth, respectively. The estimates of PCV and GCV were high for plant height, pod weight and disease index of rust. High heritability along with high genetic advance was observed in days to first flower, node at which first flower appear, days to 50 % flowering, pod length, pod weight, number of primary branches per plant, plant height, number of pods per plant, number of seeds per pod and disease index of rust. The correlation studies at genotypic and phenotypic levels revealed that pod yield per plot had significant and positive correlation with pod length, pod weight, pod width, pod girth, number of pods per plant, number of seeds per pod, shelling percentage and total soluble solids. The path coefficient analysis indicated that pod length had maximum positive direct effect on pod yield per plot followed by pod weight, plant height, node at which first flower appear, number of pods per plant, total soluble solids, days to marketable maturity, pod width, days to 50 % flowering and shelling percentage. Therefore, main emphasis should be given on these traits, while making selection in pea genotypes.

    INTEGRATED NUTRIENT MANAGEMENT IN PEA (Pisum sativum L.) UNDER SUB-MONTANE AND LOW HILLS SUBTROPICAL ZONE OF HIMACHAL PRADESH
    (COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2021-04-16) Kumari, Manisha; Kumar, Anil
    A field experiment was carried out to study the effect of integrated nutrient management in pea (Pisum sativum L.) under sub-montane and low hills subtropical zone of Himachal Pradesh at the Experimental Farm of the College of Horticulture and Forestry, Neri, Hamirpur, (HP) during rabi season 2019-20 in a randomized block design with eleven treatments replicated thrice. The soil of the experimental site was sandy loam in texture, neutral in reaction, medium in organic carbon, low in available N, medium in P and K at the initiation of the experiment. The treatments consisted of control (T1), 100 % RDF (T2), VC @ 10 t ha-1 (T3), 75 % RDF + VC (T4), 100 % RDF + VC (T5), PM @ 10 t ha-1 (T6), 75 % RDF + PM (T7), 100 % RDF + PM (T8), FYM @ 10 t ha-1 (T9), 75 % RDF + FYM (T10) and 100 % RDF + FYM (T11). Surface soil samples collected after the harvest of pea (Rabi 2019-20) from each plot were analyzed for different physical (bulk density, particle density, porosity and water holding capacity) and chemical properties (pH, EC, OC, available N, P, K, S, exchangeable Ca, Mg and DTPA extractable Fe, Cu, Zn and Mn). Grain and stover samples were also collected and analyzed for nutrient content to work out their uptake and quality of pea grain was also assessed. The results revealed that combined application of fertilizers and manures significantly influenced the plant height, number of pods per plant, number of grains per pod, shelling percentage, pod yield, stover yield and seed yield and nutrient uptake by pea. The treatment comprising of 100 % RDF + poultry manure @ 10 t ha-1 (T8) recorded the highest plant height, number of pods per plant, number of grains per pod, shelling percentage, pod, stover and seed yield. However, this treatment was closely followed by the treatment receiving 75 per cent recommended dose of fertilizer + poultry manure (T7). Moreover, addition of organic manures along with recommended dose of fertilizers improved the soil health in terms of physico-chemical properties of soil
