Abstract
An experiment was conducted during the December 1989. A full dose of NP fertilizer rainy season of 1989 to study the response of as per treatments was applied basal at the pigeonpea [Cajanus cajan (L.) Millsp.] to time of sowing. spacing and fertilizers. The field trial was Plant performance in terms of growth and conducted at 12 Navasari. There were 12 yield and attributes with wider row spacing treatment combinations, consisting of 3 row of .I20 cm. The seed yield was significantly spacings (60,90 and 120 cm) and 4 levels of higher with medium row spacing of 90 cm . nitrogen and phosphorus (0 : 0, 10 : 20,20 : compared with other row spacings, because 40 and 30 : 60 N : P kgha). The experiment of adequate plant population and also due to was laid out in factorial randomized block less competition between the plants for light, design with 4 replications on Gujarat Tur water and nutrients (Table 1).

The soil was clayey, with pH 8.1 and low (1985) also reported similar results. in available N, medium in available P and Higher grain yield recorded under 90 cm- rich in available potassium. The crop was row spacing was mainly due to optimum sown on 24 June 1989 and harvested on 18 plant density along with favourable growthReferences

The present study, therefore, was undertaken to evaluate newly developed genotypes of fababean under different sowing dates and row spacing.
The field experiment was conducted during the winter season of 199&91 at Hisar. The soil was sandy loam, low in available N(130 kgnia), medium in available phosphorus (14 kgha) and high in available potassium (420 kgha), with slightly alkaline in reaction (pH 8.2). A basal dose of 15 kg N and 45 kg P,05ha was drilled below the seed at the time of sowing. Treatments comprised 5 sowing dates (1, 15 and 30 October and 15 and 30 November) as main-plot treatment and 6 combinations of 3 row spacings (30, 45 and 60 cm) and 2 genotypes ('VH 82-1' and 'HB 180') as subplot treatments, replicated thrice in split-plot design. The crop was sown at the seed rate of 100 kglha.
The crop sown on early dates (1 and 15 October) gave significantly higher yield thanNon-conventional pulse fababean (Vicia faba L.) performs better than traditional winter-season pulse crops, viz. chickpea, pea and lentil in northern Madhya Pradesh (Srivastava and Bansal, 1988) and in Haryana (Singh et al., 1986).
