Abstract

A field experiment was conducted during February 2012 to December 2012 at College of Agriculture, under PFDC, ARS located at campus of S.K.R.A.U, Bikaner. The experiment was laid out in split - plot design with four replications and consisted of twelve treatment combinations, comprised of four water regimes (0.6, 0.8 and 1.0 volume of water through drip and another one 1.0 volume of water by surface irrigation method) and three RDF levels of NPK (75, 100 and 125% RDF). The maximum growth of plants was recorded with 1.0 volume of water through drip along with fertigation of 125 per cent RDF. As well as the maximum yield and economics were observed with 0.8 volume of water through drip along with fertigation of 100 per RDF.

Abstract

A field experiment was conducted to study the effect of different levels of drip irrigation along with various fertigation levels in fennel (Foeniculum vulgare Mill.) during Rabi season of 2010-11 at Swami Keshwanand Rajasthan Agricultural University, Bikaner. The experiment consisted of twenty one treatment combinations comprised of seven drip irrigation treatments (l 00: 100: 100 per cent ETc, 80:80:80 per cent ETc, 60:60:60 per cent ETc, 40:40:40 per cent ETc, 40:60:60 per cent ETc, 40:80:80 per cent ETc and 40: 100: 100 per cent ETc at three different development growth stages and three levels of fertigation (50, 75, 100 % recommended dose of N and P). The experiment was laid out in Split - Plot Design with three replications. Irrigation through drip was applied on the basis of ETc levels i.e. PE Kp Kc considering Kc values to be 0.70, 1.05 and 0.90 for initial (25 days), crop development (90 days) and final (35 days) stages, respectively. The fertigation was applied in six split doses at an interval of 15 days after sowing. Investigation results revealed that the the growth, flowering, yield and WUE of fennel significantly increased with different irrigation and fertigation levels. The maximum plant height (141.56 cm), number of branches per plant at 50 per cent flowering (39.22), diameter of main umbel (19.01 cm), dry matter of plant (34.46), biological yield (110.78) and test weight (8.58) were recorded under the treatment of 100 per cent Etc., whereas number of umbels per plant (21.40), number of umbellates per umbel (11.13), number of seeds per umbellate (10.63), seed yield (18.45 q ha-1) and WUE (0.542 q ha-1 cm) were recorded maximum under the treatment of 80 per cent ETc. level. However, the 100 per cent fertigation level was recorded highest plant height (108.52 cm), number of branches per plant at 50 per cent flowering (29.10), number of umbels per plant (18.25), diameter of main umbel (14.65 cm), dry matter of plant (27.33), number of umbellates per umbel (8.34), number of seeds per umbellate (8.17), seed yield (14.39 q ha-1), biological yield (62.50), test weight (7.83 g) and WUE (0.356 q ha-1 cm).

Abstract

A field experiment was conducted to study the effect of farm yard manure (FYM) and boron on growth and yield of Bael (Aegle marmelos) during, 2011-12. The results revealed that application 100 kg FYM significantly increased plant growth. Maximum fruit yield and its parameters recorded maximum viz., fruit weight (971.83 g), fruit yield (20.40 kg) and number of fruit (23.0) however, fruit cracking (4.41 %) was recorded minimum with application of 50 kg FYM. Quality parameters like TSS, sugar and ascorbic acid were also found maximum under this treatment. Application of foliar spray of borax 0.6 per cent was significantly increased fruit weight (962.0 g) and fruit yield (21.21 kg). Whereas, minimum fruit cracking (2.14 %) and peel thickness (2.41 mm) were also observed with application of 0.6 % borax. This treatment also improved quality parameters of fruit. The combined effect of FYM (50 kg tree-1) and foliar spray of borax 0.6 per cent was found significant pertaining to gain in tree height (49.20 cm), stem girth (2.75 cm), fruit weight (980.0 g) and fruit yield (36.34 q/ha) compared to control.
