    Effect of date of sowing and irrigation levels on yield of bottle gourd
    (CCSHAU, 2011) Ravinder Pal Singh; Avtar Singh
    The present study entitled “Effect of date of sowing and irrigation levels on yield of bottle gourd” was carried out at the Research Farm and Laboratory of Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during the summer season, 2010. The experiment was laid out in a factorial RBD design with three replications having three levels of irrigation (50 mm CPE,75 mm CPE and 100mm CPE), three date of sowing(25 February, 12 March, 25 March) and two cultivars (variety GH-22 and hybrid HBGH-35), thus making a total of eighteen treatments combinations. The plot size per treatment was 15 m2 (2 raised beds of 2.5×3m accommodating ten plants spaced at 60cm). The earliest appearance of first female flower, lowest node to first female flower and minimum number of days was taken for first fruiting period with D1–25 February and I1–50 mm CPE. Maximum length of fruit, fruit diameter was recorded in 25 March sowing with irrigation at 100 mm CPE. Application of irrigation at 50 mm CPE and 25 February sowing results in maximum number of branches per vine, maximum average fruit weight and longest fruiting period. Maximum number of fruits per vine, fruit yield per plant (kg/vine) and total fruit yield (q/ha) was recorded with D1–25 February and I1–50 mm CPE. The treatment combination D1 (25 February), I1 (50mm CPE) and variety V2 (HBGH-35) showed maximum net return of Rs.1,11,237/ha followed by D1V1I1 Rs.1,00,926/ha.

    Co-integration approach for estimation of supply response of major crops in Haryana
    (CCSHAU, 2011) Vikas; Manocha, Veena
    The present study is an attempt to estimate the acreage and yield response functions for major crops in Haryana within the framework of co integration and error correction model and to compare the short-run and long-run supply elasticities of major crops. The long-run acreage response to lagged price was positive and significant in the case of rice, rapeseed-mustard and sugarcane with elasticity values 0.19, 0.22 and 0.29, respectively. In case of other crops except bajra and gram, very low positive but non significant price elasticities have been observed. In the short-run, lagged price elasticities were found to be positive for all the crops. However, the positive significant values have been observed in case of rapeseed-mustard, sugarcane and bajra. The long-run acreage response to lagged year yield was found to be positive and significant in case of rice, wheat and cotton (Am.) with elasticity values 0.26, 0.18 and 0.29, respectively,. Irrigation elasticity has been observed to be positive for all the crops in the long-run, while it is positive for all the crops except gram and rapeseed-mustard in the short-run. However, only wheat and sugarcane are found to be positively and significantly responsive to irrigation in the long-run as well as short-run. The long- run yield response to price has been observed to be very low and non-significant in case of all the crops except wheat, rapeseed-mustard and sugarcane. The yield response to irrigation has been observed to be positive and significant in case of wheat, rapeseedmustard and cotton (Am.) only.
