ThesisItem Open Access Response Of Different Varieties Of Gram To Varving Levels Of Graded Dose Of N-P Fertilization And Rhizobium Inoculation(Sardarkrushinagar Dantiwada Agricultural University,Sardarkrushinagar, 1993) Kamlesh I. Patel; L.R.Patel; Department Of Agronomy,College Of Agriculture,Qujarat Agricultural University,Sardar Krusi-Iinagar-385506,February-1993,A field experiment was conducted during Rabi season of 1991 on loamy sand soil at the Instructional Farm (Agronomy), College of Agriculture, Gujarat Agricultural University, Sardar Krushinagar with a view to study the "Response of gram (Cicer arietthum L.) varieties to varying levels of graded dose of N-P fertilization and Rhizobium inoculation", Sixteen treatment combinations comprising of two gram varieties viz., ICCC-4 and Chaffa four fertility levels viz., NPc, (0+0 kg NP/ha, N1 (10+20 kg NP/ha), N2P2 (20+40 kg NP/ha) and N 3 P 3 (30+60 kg NP/ha) and two levels of Rhizobium inoculation viz., c0 (without Rhizobium inoculation) and C1 (with Rhizobium inoculation) were tested in factorial randomized block design with four replications. Between the two varieties, ICCC-4 recorded significantly higher grain yield (2275 kg/ha) and straw yield (257 kg/ha) than that of Chaffa (1901 kg grain/ha and 2155 kg straw/ha). The fertility level N2P2 (20+40 kg NP/ha) significantly Increased plant height, number of branches per ii plant, number of pods per plant, number of nodules per plant, test weight grain and straw yield and nutrients (N and F) uptake by grain and straw of the crop plant. However, it was statistically at par with the N3?3 (30+60 kg NE/ha) fertility level. '22 recorded the maximum grain yield (2426 kg/ha) and straw yield (2764 kg/ha) than those of N3?3, N1P1 and N0?0 fertility levels. The N3?3 fertility level gave significantly higher protein content (19.77 %) in comparison to N2?2, N1F1 and fertility levels. N3?3 recorded significantly less number of days to 50 per cent flowering (58.19) and number of days to maturity (106.19) than those of N0?0 and N1?1. However N 3 F 3 was statistically at par with N2F2fertility level, Seed inoculation with Rhizobium culture also was significantly effective in increasing plant height, number of branches per plant, number of pods per plant, number of nodules per plant, test weight, grain and straw yield, protein content and nutrients (N and F) uptake by grain and straw of the crop plant. The higher grain yield (2276 kg/ha) and straw yield (2587 kg/ha) were recorded under c1 (with Rhizobium inoculation), The variety ICCC-4 secured more net profit (13545 Rc/ha) and B:C ratio (2,16:1) as compared to'(7372 R/ha and 1.18:1 B : C ratio). The maximum net return (10974 /ha) was obtaid under N2?2 fertility level which was higher than those of N3?3, N1?1 and N0?0 fertility levels. However, the maximum B:C ratio (1.71 :1) was obtained under N2P2 fertility level. While Rhizobium inoculation treatment secured higher net profit (10012 /ha) and B:C ratio (1,59:1) over urilnoculated. iii Among all the possible treatment comb1natjons , the combination of Variety ICCC-4 alongwltti Rhizobium inoculation and the application of 20 kg N + 40 kg P205/ha recorded the highest grain yield (2581 kg/ha), net profit (12038 R5/ha) and BC ratio (1.861) in comparison to all other treatnt combinations0 This findings allude that sowing of gram variety ICCC-4 inoculated with Rhizobium culture and fertilized with 20 kg N and 40 kg P205 per hectare proved the best from the view point of potential production and net profit in Rabi season under North Gujarat agroclimatic condition.
