A Trial conducte at Khajura Banke

A trial conducted at khajura, Banke district, during 2004 to observe the influence of PGR’s on morphological aspects and yield of brinnjal cultivars namely Pusa Purple Long (PPL) and Pusa Purple Cluster (PPC). The treatment consisted of control, 40 ppm NNA, 10ppm GA₃, 2ppm2,

4-D, 300 ppm ethenphone, 30 ppm BAP and 5 ppm triacontanol. The first spray was made at flowering stage while other were carried out at 20 days anterval. The PGRs had no major effect on plant height, stem diameter, fruit number per plant, fruit yield and days to 100% flowering. 40ppm NAA produced highest fruit numbers per plant, fruit yield as compared to other. The PPC produced highest number of fruits per plant and yield (t/ha) than all other treatment. (Sharma 2006).

 A study was conducted studies in Chitwan during 2003/2004 to establish the PGR’s in promoting growth and yield of chilli. The cultivars were Jwala and suryamukhi  suryamukhi ranked better than Jwala for many yield-attributing parameters. Jwala was better in vegetative parameters as compared to suryamukhi. 2,4-D at 2 ppm was better in terms of fruit set, numbers of fruits per plant, fruit length, number of seeds per fruit, seed weight per fruits, 1000 seed weight and fruit yield. NAA@40ppm produced highest leaf area index. PGRs remain inffective an promoting flowering and GA₃ @ 10 ppmgave maximum amount of ascorbic acid content.( Chaudhry et al.2006).

            At BARI, joydebpur, to compare the effects of 3 PGR’s on the yield and seed and quality of chilli. Treatment NAA@10 ppm produce considerably highest fruit yield (277.8). control plants produced the lowest yield (146.6 g/plant). 10 ppm NAA treated plants showed the highest germination percentage. Control plants produced the lowest germination percentage of seed (Wahida et al. 2006)

The studies were conducted to develop a proficient micro-procedure for capsicum annuum . cultivar. ‘Morok Amuba’, using shoo-tip and axillary shoot-tip explants. A maximum shoot bubs was induced on MS media containing 10 mg/l zea. Maximum rooting and elongation of the shoot bubs were produced on MS media containing 0.5 mg/l IAA or IBA. For decapitation axillary shoot were induced on the rooted plantlets. For futher inducaton of shoot buds the axillary shoot-tips explants were used by culturing them on a media containing BAP with IAA. The shoot buds were rooted on a media supplemented with 0.5 mg/l IBA. The plantlets showed good survival percentage during transplanting. (Sanatombi et al. 2007)

Field studies were conducted at Bangladesh Agricultural Research Institute, Gazipur during 1998-1999 to compare the performances of various bell pepper (capsicum annuum L.) genotypes in response to PGR’s.  Ten genotypes namely, CP0039, CP0041, CP0043, CP0044, CP0045, CP0053, CP0054, CO0055, CP0061,and CP0068. Milstim and litosen were employed as treatment in this experiment. Due to significant variation existed among genotypes about morphological aspects, physiological characters, fruit and seed yield. CP0039 produced highest number of leaves (63.64), highest number of branches (7.36), maximum plant height (24.23cm), maximum number of fruit per plant (19) and highest seed yield (150). Maximum fruit yield (18.6*9 t ha_­­­–1) was obtained in CP0045. Maximum fruit weight (18.58g) was recorded in CP0061. seeds of CP0041 retained highest (92%) germination percentage. (Hasan-uz-zaman et al.2007)

Studies were conducted to conducted to examine the accel (BA plus GA₄₊₃), on growth and yield of chillies. Conccntrations namely 0, 10, 15, 20, and 25 mgL_-1 were used. All the conccntrations significantly increased the 2-year pooled data. (Batlang, 2008)

Experiment were conducted to study the effect of PGR’s on the yield and quality of paprika cultivar. KT-PI 19.NAA @ 25 ppm increased the number of fruit per plant, fruit set percentage and numbers of flowers per plant. NAA @ 50 ppm increased fruit weight, fresh fruit yield per plant, fresh yield per plant, fresh yield per plot, dry yield per plant, capasaicin, oleoresin, and capsanthin content. 2,4-D @10 ppm increased TSS and ascorbic acid contents. (Kannan et al.2008)

    

Trials were carried out during 2006-2007 to computer the effect of PGR’s namely 40 ppm NAA, 50 ppm GA_3, CCC and 5 ppm 2,4-D and method of application in paprika chilli  cultiva. Kt-PI-19. 40 ppm NAA applied at flower bud initiation was most effective in increasing plant height, 1000 seed weight, of fruit per plant, fruit yield per hectare, seed yield per plant and seed yield per hectare. 40 ppm NAA and 50 ppm GA₃ applied at flower bud initiation were most effective in increasing fruit and seed yield. (Shantappa et al. 2009)

Series of experiments involving chilli (capsicum annuum) cultivar phule jyoti were carried out during 2004-2005 in Rahuri, Maharashtra, India. The treatment were 20 ppm NAA, 140 and 280 ppm B, 0.25% and 0.50% znso₄, 140 ppm B+0.25% Znso₄₊ 20 ppm NAA, 280 ppm B+0.25% znso₄ +20 ppm NAA, 280 ppm B+0.50% znso₄ +20 ppm NAA, and control. The PGR’s along with micronutrients were applied twice at 15 days interval starting just before flowering. Foliar application of PGR’s and micronutrients at flowering increased growth and yield in chilli.20 ppm NAA applied at flowering produced highest fruit yield as compared to all other treatments. (Bhalekar et al; 2009)

      The experiment were conducted at coconut at Garden of Tamil Nadu Agricultural University, Coimbatore during July-December 2002 to evalutate the effects of PGR’s on paprika cultivate. Kt-PI-19. the GA3 application at 50ppm produced highest number of primary branches per plant. Application of NAA at 50ppm resulted in highest number of leaves per plant. Maximum plant height, early flowering and maximum fruit yield. (Mannam et al 2009).

            The study was conducted to observe ill effects of tropical climate frequently such as high temperature, laow humidity and other relative disturbs on thecrop husbandry of paprika chilli in relation to their plant growth, development and yield. The major issues of low productivity in paprika chili were increased fruit drop percentage and decreased fruit set percentage and delayed flowering. NAA had promontory effects on plant growth and yield parameters. GA3 application significantly affected the growth  and yield parameters. (Kannan et at.2009).

            The trial was carried out to examine the effects of PGR’s on growth attributes and fruit yield in chilli. All the PGR’s and nutrient treatments increased the growth attributes viz, AGR, CGR, RGR and NAR  Cyocel treatment decreased leaf area with an increase in SLW. All the PGR’s and nutrient treatments significantly increased fruit yield as comprared to control (Gollagi et . 2009).

            The investigation were carried out on the pare and post harvest physiology and qulaiyf responses of green pepper (Capsicum annumn) L cultivar Standar p.13/0211003-01- Agris’ on exogenous foliar application of 100uM GA3, 100mgL-1 Prohexadione Calcium 100 mgL-1 Cycocel and 100 mgL-1 Etherphone. Among PGRs, 100uM GA3 was efficient to induce floweintg and bette for vegetative aspects. The concentration of chlorophyll a+b  in leaves were distinctly inhibited by the application of GA3 Prohexadione Calcium, Cycocel and Ethephon. The Brix content and maturity index wrew reduced after application of Prohexamone-Calcium, Cycocel and Etherphon. (Georgia et al. 2010).  The studies wrer conducted to observe the effects on chili plants sprayed with Miyobi solution 30 days after transplanting. Miyobi application increased plant height, number of branches, leaf number, root length number and wieth, stem weieth, total dry biomass, chlorophyll content, fruit per plant and fruit yield as compared to control. Opposite trend was examined in fruit size. The morphological, biochemical, yield increased by applying Miyobi solution (Rana etat. 2011).

            The effect of bio regulators were studied in Garhwal region on the growth and yield attributes in capsicum unde protected conditions. The research revealed that the spray of bio regulators had major effect on the growth and yield of chili. Plant height, number of secondary branches, lef area index, days taken to flowering number of flowers per plant, number of fruits per plant, number of fruits per plant, fruit weight and yield per plot increase when sprayed with NAA @ 50ppm. NAA @ 50 ppm produced maximum plant height (114.38) and maximum fruit yield (1.85 kg ) per plant. (Sindh.el.2012).
