Abstract

A field experiment on effect of clay mixing, irrigation and sulphur on growth and yield of fenugreek (Trigonella foenum- graecum L.) on loamy sand soil, was conducted at S.K.N. College of Agriculture, Jobner (Rajasthan) during Rabi seasons 2006-07 and 2007-08. The experiment consisted of 36 treatment combinations of 3 levels of clay mixing (0, 1 and 2 %), 3 levels of irrigation [4 application of irrigation at lateral bud initiation (LBI) + flower initiation (FI)+ pod initiation (PI) + grain development (GD), 6 application of irrigation at LBI + PI and 8 irrigations applied at all the phenological stages of crop growth (LBI + branching + FI + full flowering + PI + pod enlargement and grain formation + GD + ripening] as main plot treatments and 4 levels of sulphur (0, 20, 40 and 60 kg S/ha through gypsum) as sub plot treatments was laid out in split plot design with three replications. The results indicated that application of clay @ 2 per cent gave significantly higher growth, yield attributes and yield and remained at par with application of clay @ 1 per cent in both the year as well pooled mean over control. The results further indicate that application of 8 irrigation resulted in significantly higher growth, yield attributes and yield and remained at par with the application of 6 irrigation in pods per plant and seeds per pods in both the years as well as pooled mean over the control. The application of sulphur @ 40 kg/ha gave significantly higher the growth, yield attributes and yield in pooled mean basis over rest of treatments.

Abstract

A field experiment was conducted during summer season of 2012 on medium black soil to the study of effect of nitrogen and phosphorus levels on uptake by cowpea (Vigna unguiculata (L.) Walp) and residual N, P and K content in soil. The experiment consisted of four treatments of nitrogen levels (control, 20, 30 and 40 kg/ha) and four treatments of phosphorus levels (control, 40 60 and 80 kg P₂O₅/ha) thereby making sixteen treatment combinations tested in Factorial Randomized Block Design with three replications. The results indicated that the application of nitrogen @ 40 kg/ha gave the maximum and significantly higher the N, P and K uptake and residual content in soil and remained at par with 20 and 30 kg N/ha over control. Results further indicated that the application of phosphorus @ 80 kg/ha gave the maximum and significantly higher the N, P and K uptake and residual content in soil and remained at par with 40 and 60 kg P₂O₅/ha over control.
