Yield, Water Use Efficiency and Economics of Drip Fertigated Broccoli (Brassica Oleracea Var. Italica)

Communications in Soil Science and Plant Analysis (2021)

Renu Kapoor Sanjeev K. Sandal

The present study was conducted with the objectives of evaluating the effect of drip irrigation and fertigation levels on soil water retention, water use efficiency, and productivity of broccoli. The treatments comprised of (a) two-drip irrigation levels, namely, I0.4 – Drip at 40% Cumulative pan evaporation (CPE) and I0.8 – Drip at 80% CPE (b) Four fertigation levels, namely, F50 – 50% recommended dose of fertilizer (RDF), F100 – 100% RDF, F150 – 150% RDF and F200 – 200% RDF (c) Farmer’s practice – FYM @ 1 kg m−2 + 10 g m−2 IFFCO + 2 g L−1 of 19:19:19 at 15-day intervals and drip irrigation @ 2 L m−2 daily (d) Recommended Practice (RP)- 100% RDF + drip at 100% CPE replicated thrice. Results indicated that the soil moisture increased with increase in drip irrigation level from I0.4 to I0.8 with very less depletion rate per day resulting in the soil moisture content near the field capacity in all drip irrigated treatments. Among the drip fertigation treatments, higher fertigation doses (200% RDF and 150% RDF in combination with 40 and 80% CPE) produced more yield but also resulted in high cost of cultivation, which leads to low benefit cost ratio. However, fertigation treatment I0.8F50 resulted in high benefit cost ratio with higher water use efficiency and fertilizer expense efficiency, which further saved water and fertilizers to the tune of 20 and 50% as compared to recommended practice to maintain same yield levels in broccoli.

Effect of ZnSO4 on yield and quality of Gobhi Sarson (Brassica napus) var GSC-7

Journal of Mountain Research (2024)

S. D. Dhiman Paranjay Rohiwala Jaya Chaudhary Rajeev Raina Renu Kapoor

The present investigation was conducted to assess the effect of soil and foliar application of ZnSO4 on Gobhi Sarson var GSC-7. The experiment was conducted for two consecutive rabi seasons of 2022-23 and 2023-24 at Bhagot farm of KVK Chamba (Himachal Pradesh), Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, to study the effect of ZnSO4 on growth, yield, uptake of nutrients and quality of seeds in Gobhi sarson. There were six treatments viz. T1: RDF + soil application of ZnSO4 @ 25kg/ha, T2: RDF + foliar application of ZnSO4 @ 5g/litre at 45 days after sowing, T3: RDF + foliar application of ZnSO4 @ 5g/litre at 45 and 60 days after sowing, T4: RDF + foliar application of ZnSO4 @ 5g/litre at 45 and 75 days after sowing T5: RDF, and T6: Farmer’s practice i.e. application of FYM only. The experiment was laid out in randomized complete block design in replication of three. The results indicated that soil application of RDF + ZnSO4 @ 25 kg/ha was most effective which was followed by RDF + ZnSO4 spray @ 5g/L 45 and 60 DAS in reducing the number of days for flower initiation (88.71 and 88.20), increased branches bearing pods (15.54 and 14.93), plant height (190.33 and 188.33), number of siliquae/plant (215.67 and 214.30), 1000 seed weight (4.34 g and 4.29 g), seed yield/plant (6.33 g and 6.27 g), oil yield (337.42 kg/ha and 334.58 kg/ha), protein yield (357 kg/ha and 353.67 kg/ha), germination % (93.33 and 92.67) and other seed quality parameters. The soil application of ZnSO4 at 25 kg/ha or foliar application @ 5g/litre at 45 and 60 days after sowing were effective treatments in enhancing growth, yield, uptake, status of nutrients and quality of produce in Gobhi sarson in present investigation.

Fetal loss and contraceptive acceptance among the Bhopal gas victims

Biodemography and Social Biology (1991)

Renu Kapoor

Abstract The rates of fetal loss and family planning acceptance among Bhopal gas victims from 1984 to 1989 were compared to those of a control group. In all, 136 eligible women in the affected area and 139 women in the control area were interviewed. Care was taken to ensure that these women had conceived at least once during the previous five years. The fetal loss rate among the gas‐affected women was abnormally high (26.3 per cent) compared to that of women in the control area (7.8 per cent). Family planning acceptance in both areas was similar, with most women using permanent methods. In the case of temporary methods, the percentage of use was higher in the gas‐affected area.

RESPONSE OF EXOTIC VEGETABLES TO PLANT SPACING, FERTILIZATION, AND INSECT PEST MANAGEMENT UNDER SUBTROPICAL REGION OF WESTERN HIMALAYAS OF HIMACHAL PRADESH

Innovare Journal of Agricultural Sciences (2024)

Renu Kapoor Dharminder Kumar Chandel VGS Anil Kumar ANURAG SHARMA

Objective: The study was conducted with the objective to study the effect of different plant spacing and fertilizer treatments on the yield and growth parameters of exotic vegetables. Methods: The study was carried out at the experimental farm of Regional Horticultural Research and Training Station Jachh (32° 16’ N latitude and 75°51’ E longitude, 440 m above mean sea level) during the year 2021–22. The experiment was laid out in a factorial randomized complete block design with three replications. The treatments were comprised of three levels of fertilizers (120, 100, 75% RDF) and two levels of spacing. Results: The observations revealed significant variations in the fresh yield of Kale, Parsley, and Celery in response to different fertilizer doses and plant spacing. Specifically, the fresh yield of Kale, Parsley, and Celery showed significant improvements with higher levels of fertilization (F1) and narrow plant spacing (S2). In addition, the number of leaves per plant increased with higher fertilizer doses but did not vary significantly across different spacing levels in all three crops. While the leaf length and width of Kale were not significant, the leaf length of Parsley and Celery varied significantly with increasing fertilizer doses. Furthermore, among the three crops studied, Kale was observed to be infested by aphids, particularly Brevicoryne brassicae, during the crop period. The application of imidacloprid (0.5 ml/L) and chlorantraniliprole (0.4 ml/L) demonstrated effective management of this pest, providing better results for pest control. Conclusion: Fresh yield of kale, parsley, and celery increased under high level of fertilization and narrow spacing as well. Moreover, imidacloprid and chlorantraniliprole can be utilized for the management of cabbage aphids in Kale crop.

Growth and yield response of broccoli (Brassica oleracea var. italica) to varying drip irrigation and fertigation levels

The Indian Journal of Agricultural Sciences (2019)

Renu Kapoor Sanjeev K. Sandal

The study was conducted during 2013â€“14 and 2014â€“15 at experimental farm of Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya, Palampur with the objective to evaluate the effect of drip irrigation and NPK fertigation levels on crop growth, nutrient uptake, nutrient use efficiency and productivity of broccoli (Brassica oleracea var. italica) The treatment combinations comprised two irrigation levels (0.4 and 0.8 CPE), four fertigation levels (50, 100, 150 and 200% RDF), one farmerâ€™s practice (FYM @ 1 kg/m2 + 10 g/m2 IFFCO (basal) + 2 g/L of 19:19:19 at 15 days intervals and drip irrigation applied @ 2 L/m2 daily), and one recommended practice (100% RDF by conventional method + drip irrigation at 100% CPE). The results revealed that plants grown under fertigation had more number of leaves and plant height as compared to those grown under conventional method. Study on drip fertigation revealed that root length, volume and mass were significantly higher with F200 over F100 and F50 leading to higher marketable yield. However, fertigation treatment F50 resulted in high nutrient use efficiency and saving of 50% and 20â€“60% fertilizers and water, respectively, as compared to conventional fertilization with drip irrigation at I1.0 to maintain the same yield levels in broccoli.
