ThesisItem Open Access Effect of pruning intensity on yield and fruit quality of sweet orange cultivars under high density plantation(College of Horticulture and Forestry Dr YSP UHF, Neri, Hamirpur(H.P.), 2024-01-09) Sharma, Aditi; Banyal, Sanjeev K.A field experiment was conducted during 2022-23 on 5 years old citrus orchard “to study the effect of pruning intensity on yield and fruit quality of sweet orange cultivars under high density plantation” of variety Blood Red, and Mosambi in the experimental farm of the Department of Fruit Science, College of Horticulture and Forestry, Neri, Hamirpur (HP). The experiment was laid out in factorial randomized block design with four replications. The investigation comprised of five treatments involving treatment T1 (2.5 cm Heading back), T2 (5cm Heading back),T3 (10 cm Heading back),T4 (15 cm Heading back), T5 (control). In general the higher intensity of pruning enhanced vegetative growth that observed in treatment T4 (64.79 cm), stem girth (2.85 cm), tree-spread (41.33 cm), number of new shoots (5.50). All flowering characteristics including (time of bud break, time of first flowering, fruit set and full bloom) were recorded earlier in treatment T3. Lower intensity of pruning T2 (5 cm Heading Back) & T1 (2.5 cm Heading Back) resulted in lesser vegetative growth as compared to 15 cm Heading Back but there was reduction in fruit yield and quality as well. Maximum fruit yield (14.16 kg) and fruit quality that includes TSS (8.73 °B), reducing sugar (3.68 %) and total sugar (6.23 %) was recorded in treatment T4.Therefore (15 cm Heading Back) can be regarded as the best treatment in the present study.ThesisItem Open Access Evaluation of newer molecules against sucking pest complex in Bt cotton (Gossypium hirsutum L.)(RVSKVV, Gwalior (M.P.), 2022) Sharma, Aditi; Badaya, Dr. A. K.ThesisItem Open Access Nutritional Status of Pregnant Women and Its Effect on Lactation Performance(CCSHAU,HiSAR, 2020-09) Sharma, Aditi; Sindhu, Sangeeta CCurrent study was undertaken at Hisar City of Haryana State in North India to assess the nutritional status of pregnant and lactating women and to assess its impact on lactation performance. One hundred pregnant women in last trimester of pregnancy were selected randomly from the government and private hospitals. The respondents were again contacted at three different stages of lactation viz. 15 days post-partum, three months post-partum and six months post-partum. Nutritional status was assessed in terms of anthropometric measurements and dietary intake. Pregnancy outcome was evaluated in terms of gestational weight gain and baby birth weight. Lactation outcome was evaluated in terms of maternal weight loss, baby weight gain, milk output and exclusive breast feeding for 6 months. Majority (n=57) belonged to the age group of 24-30 years, were graduate (n=48); were employed (n=44); sedentary workers (100 %) and had family income between Rs. 30000- 60000/- per month (n=51). It was first parity for majority of respondents (n=47). No major metabolic or mental health problems were evident from their medical records. The reported problems were hypertension (n=5), hypothyroidism (n=3) and insomnia (n=1). Mean blood pressure was 116/81± 3.12. Majority of respondents (n=52) had Hb levels more than 11 gm/100 ml. Majority (n=65) had normal weight for height (pre pregnancy) with BMI ranging from 19-24.9. None of the respondents was found as underweight during lactation period. Namely 54, 65 and 41 respondents were overweight/obese during the three respective periods of lactation.Intake for all the food groups was significantly (P ≤ 0.05) lower than recommended intake for pregnant women. Dietary intake of most nutrients at three months postpartum was significantly (P≤0.05) higher than pre partum or other postpartum lactation stages. Mean gestational weight gain during pregnancy was 11.4 ± 2.32 kg. Mean birth weight of babies was 3.21 ± 1.41kg. Only nine babies had low birth weight (<2.5kg). Average milk output was 22.41±3.0, 133.51±3.4 and 168.16±3.1g/lactation during the three phases of lactation and corresponding baby weight was 3.64±1.81, 5.58±2.73 and 8.21±1.34 kg. Supplements in form of cow milk and formula milk were introduced as early as first fortnight postpartum. Only 16 per cent of respondents were practicing exclusive breast feed up to six months. Significant (p≤ 0.05) positive correlation was observed between BMI of respondents at last month pregnancy and birth weight of child ; weight gain of mothers during pregnancy and birth weight of child as well as between mid-arm circumference of mothers at last month pregnancy and birth weight of child. Also a significant (P≤ 0.05) positive correlation was observed between energy intakes during pregnancy/ lactation and milk output except at sixth month of lactation. Another significant (P≤ 0.05) positive correlation was observed between protein intakes during pregnancy/ lactation and milk output at respective intervals except at sixth month of lactation. Dietary fat intake by mothers during pregnancy as well as at 15 days postpartum was found to have significant (P≤ 0.05) positive correlation with milk output at 15 days postpartum.
