    Response of okra [Abelmoschus esculentus (L.) Moench] to levels of irrigation, nitrogen and mulch under drip irrigation system
    (CCSHAU, Hisar, 2022-10) Sangeet Kumar; Batra, V. K.
    The field experiment was conducted during spring summer season of 2019-20 and 2020-21 at Research Farm of the Department, Vegetable Science, CCS Haryana Agricultural University, Hisar to study the response of okra to levels of irrigation, nitrogen and mulch under drip irrigation system. The experiment was laid out in a Split-Split Plot Design with 27 treatment combinations comprised of three levels of drip irrigation (80, 100 and 120% ET) as main plots, three levels of nitrogen fertigation (75, 100, and 125 kg/ha) as sub plots and three level of mulch (no mulch, white plastic mulch and yellow plastic mulch) as sub-sub plots and one control treatment replicated thrice. The growth parameters were recorded maximum under drip irrigation at 120% ET, 125 kg/N per ha and yellow plastic mulch as compared to other levels, respectively, whereas all the yield and quality parameters were recorded maximum with white plastic mulch, 125 kg/N per ha and drip irrigation at 100 and 80% ET, respectively, as compared to other levels. The use of plastic mulch minimizes the weed population and maximizes the weed control efficiency. The lowest Weed dry weight and weed density and maximum weed control efficiency were recorded with white plastic mulch. However, the maximum WUE (71.03, 60.10 and 65.56 kg/ha/mm, respectively) and NUE (152.47, 148.31 and 150.39 kg/ha/kg, respectively) was observed from the level drip irrigation at 80% ET and 125 kg/N per ha, respectively. Further, the interaction of irrigation with nitrogen fertigation and mulch significantly affected almost all the growth, yield and quality parameters. The highest net returns (Rs.128289/ha and Rs.124478/ha) and benefit cost ratio (2.00 and 1.99) were recorded in the treatment drip irrigation at 100% ET with 125 kg/ha nitrogen fertigation and white plastic mulch as compared to rest of the treatments combinations. In the end it is concluded that for achieving the higher yield, better quality, maximum NUE, WUE and net profit, the okra crop can be irrigated at 80% ET through drip irrigation in combination with 125 kg/ha nitrogen fertigation and milky white coloured plastic mulch.

    Effect of intercropping on growth and yield of brinjal and palak
    (CCSHAU, 2017) Sangeet Kumar; Dhankhar, Surender Kumar
    The present investigation entitled “Effect of intercropping on growth and yield of brinjal and palak” was carried out at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during autumn-winter season of 2016-17. The experimental treatments viz., T1-brinjal sole crop of 60 X 60 cm , T2-palak (sole) 20 X 5cm, T3-paired row brinjal sole crop 30/at spacing of 60 X 60 cm , T4-brinjal + palak (broadcasting) T5-brinjal + palak single row, T6-brinjal + palak two rows, T7-brinjal + palak three rows, T8-paired row brinjal + palak single row, T9-paired row brinjal + palak two rows, T10-paired row brinjal + palak three rows and T11-paired row brinjal + palak four rows were laid out in a Randomized Block Design (RBD) with three replications. Based on the research investigation it was found that the intercropping of palak with brinjal significantly decreased plant height (cm), number of fruits per plant, fruit characters, days to first picking and total fruit yield (q/ha) in brinjal and leaf length, petiole length, leaf width, stem length, days to harvesting and leaf yield (q/ha) in palak. Growth and yield attributes of sole brinjal (60 X 60 cm) and sole palak (20 X 5 cm) exceeded over rest of the treatments due to minimum competition. Brinjal + palak single row gave highest net returns (Rs. 222652) and B: C Ratio (3.76) due to low cost of production, followed by treatment paired row brinjal + palak (two rows) with Net returns (Rs. 218052) and B: C Ratio (3.52). Also Paired row brinjal + palak (two rows) intercropping system gave highest LER (1.84), ATER (1.46), maximum Gross returns (Rs. 304598), BEY (507.6 q/ha) and PEY (217.6 q/ha) followed by treatment Brinjal + palak single row with LER (1.76), ATER (1.43), Gross return (Rs. 303442), BEY(505.6n q/ha) and PEY(216.7 q/ha). It has been concluded that brinjal normal or paired row intercropped with palak single row could be more remunerative for earning maximum net returns than the brinjal sole crop.
