C.; Salvi V. G.; Salvi B. R.; Joshi M. S.The present investigation entitled “Studies on effect of soluble fertilizers on growth, flowering and yield of bush pepper (Piper nigrum L.)” was carried out at college of Horticulture, Dapoli. Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli. Dist. Ratnagiri (Maharashtra) during 2020-21 and 2021- 2022. The objectives of studies were to find out the effect of soluble fertilizers on growth, flowering and yield parameters of bush pepper. The present investigation comprises of seven treatments viz. T1- Application of 25 percent recommended fertilizer dose through water soluble fertilizers (WSF), T2- Application of 50 per cent recommended fertilizer dose through WSF, T3- Application of 75 percent recommended fertilizer dose through WSF, T4- Application of 100 percent recommended fertilizer dose through WSF, T5- Application of 125 percent recommended fertilizer dose through WSF, T5- Application of 150 percent recommended fertilizer dose through WSF and T7 (Control) – Application of 100 per cent RDF through straight fertilizers replicated four times and analyzed by Randomized block design. The growth parameters like plant height, AGR, RGR, number of primary branches, number of secondary branches, number of leaves per branch, total number of leaves per plant, total leaf area LAI and plant girth was recorded at 90 days interval whereas, shoot length, number of new shoots, internodal length, number of spikes and number of new spikes was recorded at 60 days interval. At 720 days after planting treatment T5 i.e. application of 125 per cent RDF through WSF at weekly interval recorded maximum plant height (102.30cm), AGR (0.166 cm/day), RGR (2.010cm/cm/day), shoot length (70.58cm), number of new shoots per plant (9.01), number of primary and secondary branches per plant (7.23 and 3.78, respectively), Total number of leaves per plant, total leaf area and Leaf Area Index (194.45, 22538.09 cm2 and 0.724respectively) and plant girth (2.82cm). At the end of the 1st and 2nd year maximum internodal length was registered by treatment T5 where plants were supplied with 125 per cent RDF through soluble form i.e., 11.51 and 12.55cm, respectively. However, at 360 days after planting (DAP) and 720 DAP maximum leaf area (109.96cm2 and 121.62 cm2) was observed in treatment T5. After harvesting (at 720 DAP) maximum shoot length (103.00cm), fresh shoot weight (990.75g), dry shoot weight (234.25g), root length (80.75cm), number of primary and secondary roots (19.00 and 77.25, respectively), fresh and dry root weight 123.00 and 67.75g, respectively) and shoot to root weight ratio (28.87) was reported by the treatment in which plants were supplied with 125 per cent RDF through soluble form i.e. (T5). At 720 days after planting maximum number of spikes and new spikes per plant was recorded in treatment T5 i.e. 104.50 and 194.72, respectively. At the end of the 2nd year minimum days for harvesting (232.85) and at harvesting maximum spike length (19.08cm), fresh spike weight (16.35g), number of berries per spike 85.25), fresh berry weight per spike (15.30g) and 100 fresh berry weight (20.55g) was observed in treatment T5. In respect of two years cumulative fresh berry yield per plant (2340.83g), dry berry yield per plant (772.47g), dry berry yield per plot (23.17kg), dry berry yield per guntha (38.62kg) and dry berry yield per hectare (3.79t), treatment T5 (application of 125 % RDF through WSF) found to be best with highest B:C ratio of 2.32 per guntha and 2.27 per hectare. The soil analysis at the end of both the years of experimentation showed that pH and electrical conductivity among different levels of fertilizers was non-significant whereas, organic carbon, available nitrogen, available phosphorus and available potassium differs significantly with different levels of fertilizers. Increasing trend was observed in case of available NPK with increased in levels of fertilizers however, organic carbon decreased with increasing fertilizer levels. At the end of second year maximum available nitrogen (259.50kg ha-1), available phosphorus (15.62kg ha-1) and available potassium (406.00 kg ha-1) was observed in treatment T6 where plants were supplied with 150 per cent RDF through WSF whereas, treatment T7 (application of 100% RDF through straight fertilizer) recorded maximum organic carbon (18.92g kg-1). Correlation study clearly stated that the yield was highly significantly correlated with plant height, number of leaves, number of spikes, available nitrogen, available potassium and organic carbon content in soil thereby revealing that the increase in the said factors helped to increase the yield. The highest net returns of Rs. 13,172.35/- per guntha and Rs. 12,83,619/- per hectare with B: C ratio (2.32 and 2.27, respectively) was recorded in treatment (T5) when plants were supplied with 125 per cent of recommended dose of fertilizer in soluble form.ThesisItem Open Access Influence of nitrogen levels, spacing, bio-fertilizers and organic manures on growth and yield of turmeric (Curcuma longa L) var.

From above findings, it could be concluded that the turmeric planted at the spacing 45 cm ×15 cm with the application of 300 kg nitrogen per ha and vermicompost 7.5 t ha-1 and 5 kg ha-1 PSB along with common dose of 50 kg phosphorus and 150 kg potassium per ha under Konkan agro-climatic conditions was found economicalThesisItem Open Access EFFECT OF DIFFERENT PLANT GROWTH PROMOTERS ON SURVIVAL AND GROWTH OF BUSH PEPPER (Piper nigrum L.) (Accession No. T06859)(dr. B.S.KKV., Dapoli, 2020-09) PAWAR, JYOTI TANAJI; Khandekar, R. G.The present investigation entitled “Effect of different plant growth promoters on, survival and growth of bush pepper cuttings (Piper nigrum L.)” was conducted at the College of Horticulture, Dapoli, and Dist. Ratnagiri during the year 20192020. The experiment was conducted in Randomized Block Design (RBD) with ten treatments and 3 replications. The treatments were T1-Vermiwash 5 % drenching, T2-Vermiwash 10 % drenching, T3-Vermiwash 15 % drenching, T4-Cow urine 5 % drenching, T5-Cow urine 10 % drenching and T6-Cow urine 15 %,T7 –Humic acid 0.05 % drenching, T8 -Humic acid 0.1 % drenching, T9 -Humic acid 0.2 % drenching, T10 –Keradix. Growth parameters of bush pepper cutting viz. days required for first sprouting, days required for peak sprouting and days required for last sprouting, sprouting percentage ,survival percentage, number of leaves per cutting, number of shoots per cutting, length of shoots per cutting, plant height, girth of plant ,leaf area, relative growth rate and absolute growth rate, root length, were significantly influenced by different plant growth promoters drenching. In treatment T9 (i.e. 0.2 % drenching) high survival per cent (55.45 %), high sprouting per cent (98.00), less days required for first sprouting (16.04), less days required for peak sprouting (38.16), less days required for last sprouting (50.13), more number of leaves per cutting (6.17), more number of shoot (8.05), highest length of shoot (12.96 cm), plant height (36.43 cm), girth of plant (5.73 mm). In treatment T3 ( i.e. Vermiwash 15%) maximum leaf area (105.53 cm2), In treatment T7 the length of root (40.00cm), were observed which was the best performed among treatments under study. The lowest performance in T10 (i.e. Keradix) lowest sprouting percentage (87.00), lowest survival percentage T10 i.e. keradix (44.82). In treatment T4 (i.e. Cow urine 5 % drenching ) of lowest leaves per cutting (4.73).In treatment T4 ( i.e. Cow urine 5%) lowest number of shoot (5.56). In treatment T1 ( i.e. Vermiwash 5%) lowest length of shoot (10.04), plant height (26.93). In treatment T10 ( i.e. Keradix) lowest girth (3.32 mm). Treatment T2 (i.e. Vermiwash 10%) lowest leaf area (78.20 cm2).In treatment T8 ( i.e. Humic acid 0.1%) lowest realative growth rate (0.00021 cm/cm/day).In treatment T8 (Humic acid 0.1%) lowest absolute growth rate(0.01600 cm/cm/day). In treatment T5 ( i.e.Cow urine 10%) lowest root length (15.9). In treatment T4 ( i.e.Vermiwash 5%) minimum no. Of days required for first sprouting (21.48), In treatment T10 ( i.e.Keradix) maximum no. Of days require for peak sprouting (45.52), In treatment T4( i.e. Cow urine 5%) maximum no. Of days required for last sprouting (61.14). The different plant growth promoters drenching at various concentrations improve sprouting, survival, and growth performance of bush pepper cuttings in comparison to control i.e. Keradix. Thus, from the present investigation it can be concluded that different plant growth promoters drenching gave more sprouting, survival, and better growth of bush pepper cuttings. . Moreover among all the concentrations of plant growth promoters drenching studied, treatment T5 (i.e. cow urine 10% drenching) recorded highest net profit of (Rs. 2143/-) with B : C ratio (1.81). The other treatment which recorded B : C ratio above control (1.50), were as treaments T3 (1.75), T2 (1.74), T1 (1.72), T7 (1.68), T8 & T6 (1.62), T4 (1.61) and T9 (1.59), respectively. As present study is only of one season, further invesstigation is necessary so as to confirm these results.ThesisItem Open Access EFFECT OF DIFFERENT POTTING MEDIA ON ROOTING OF BLACK PEPPER (Piper nigrum L.) CUTTINGS VARIETY: PANNIYUR 1 (Accession No. T06855)(dr. B.S.KKV., Dapoli, 2020-08) KHALE, PRITAM PANDURANG; Haldankar, P. M.The present investigation entitled ‘Effect of different potting media on rooting of black pepper (Piper nigrum L.) cuttings variety: Panniyur 1’ was carried out at College of Horticulture, Dapoli, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli (Maharashtra) during July-December 2019. The experiment was laid out in Randomized Block Design with nine potting mixture treatments namely, T1 = Soil + FYM (3:1), T2 = Soil + Vermicompost (1:1), T3 = Soil + Vermicompost + Rice husk (3:5:2), T4 = Soil + Vermicompost + Cocopeat (3:5:2), T5 = Soil + FYM + Vermicompost + Cocopeat (3:3:2:2), T6 = Soil + FYM + Vermicompost + Rice Husk (3:3:2:2), T7 = Soil + Vermicompost + Cocopeat + Rice husk (3:3:2:2), T8 = Soil + FYM + Cocopeat + Rice husk + Cocopeat (3:3:2:2), T9 = Soil + Cocopeat + Rice husk (3:3.5:3.5) in 10 × 20 cm bag size and replicated three times. The morphological parameters viz., days required for sprouting, sprouting (%), leaf area (cm2), number of leaves, number of roots, length of shoot (cm), length of root (cm), fresh weight of shoot (g), fresh weight of roots (g), dry weight of roots (g), dry weight of shoot (g), total dry weight of plant (g), root to shoot ratio of plant, survival (%) and mortality (%). , length of shoot (cm), length of root (cm), fresh weight of shoot (g), fresh weight of roots (g), dry weight of roots (g), dry weight of shoot (g), total dry weight of plant (g), root to shoot ratio of plant, survival (%) and mortality (%). Treatment T5 (Soil + FYM + Vermicompost + Coco peat = 3:3:2:2) recorded minimum days (18.40) for sprouting and maximum sprouting (64.67%). After 6 months of planting T5 registered the longest shoot length (81.01cm), longest root length (28.27cm), maximum fresh weight of shoot (43.93g), fresh weight of roots (5.07g), dry weight of shoot (6.67g), dry weight of roots (1.80g), number of leaves (11.33) and total dry weight (9.47g) with the highest survival (64.67%) and lowest mortality (35.33%). From present investigation, it was concluded that potting mixture containing Soil + FYM + Vermicompost + Cocopeat (3:3:2:2) resulted into better growth and superior morphological traits of black pepper cuttings. However, this is only one season data and confirmation of results by continuing the experimentation for the next 2 to 3 years is essential.ThesisItem Open Access STUDIES ON VARIETAL RESPONSE AND OPTIMIZATION OF NITROGEN LEVELS TO TURMERIC (Curcuma longa L.) cv. SALEM (Accession No. T06817)(dr. B.S.KKV., Dapoli, 2020-09) SATELKAR, AJIT GURUNATH; Salvi, B. R.The investigation entitled “Studies on varietal response and optimization of nitrogen levels to turmeric (Curcuma longa L.) cv. Salem” was undertaken at College of Horticulture, Dr.B.S.K.K.V, Dapoli, District-Ratnagiri (M.S.) during May 2019 to Feb 2020. The experiments under study were carried out in Randomized Block Design (RBD) with thirty treatments of different turmeric varieties as one set of experiment and four treatments of nitrogen levels to the variety Salem as second set of experiment. In first experiment, the thirty varieties of turmeric were evaluated under Konkan climatic conditions. All varieties under study differed in various growth parameters, yield parameters and curcumin content. However among the selections tested, the varieties Salem and PDKV Waigaon showed better performance under Konkan climatic conditions. The maximum yield of 36.72 ton per hectare was recorded by Salem followed by PDKV Waigaon with 30.92 ton per hectare which were at par with each other. The highest curcumin content was recorded in PDKV Waigaon (5.2%) and Salem (4.4%) which were at par with each other. of 36.72 ton per hectare was recorded by Salem followed by PDKV Waigaon with 30.92 ton per hectare which were at par with each other. The highest curcumin content was recorded in PDKV Waigaon (5.2%) and Salem (4.4%) which were at par with each other. In second experiment, the effect of different nitrogen levels on yield of turmeric cv. Salem observed marked improvement in growth and yield attributes without affecting the quality parameters i.e. curcumin content. The treatment T1 with 25 t FYM + 200 Kg N + 50Kg P2O5 + 150 kg K2O per hector recorded the maximum yield of 36.11 ton per hectare in turmeric cv. Salem. Considering the yield and curcumin content in Salem and PDKV Waigaon at both locations of College of Horticulture Dapoli and Central Experimental Station, Wakawali, Asond, it seems that both varieties can perform better under Konkan agroclimatic conditions. Instead of going for higher dose of N the various other levels of P and K with some micronutrients supplementation may give further promising results which needs to be studied in future. However, the continuous experimentation for at least three consecutive seasons is essential to confirm above findings.ThesisItem Open Access EFFECT OF POTTING MEDIA AND SEASON OF TRANSPLANTING ON GROWTH AND SURVIVAL OF CASHEW GRAFTS (Anacardium occidentale L.) CV. VENGURLA-4 (Accession No. T06691)(dbskkv., Dapoli, 2019) KHEDEKAR, SURAJ PANDURANG; Bhingarde, R. T.The present investigation entitled “Effect of potting media and season of transplanting on growth and survival of cashew grafts (Anacardium occidentale L.) cv. Vengurla 4” was conducted at nursery No.1, Department of Horticulture, College of Agriculture Dr. B. S. K. K. V. Dapoli, Dist. Ratnagiri during the year 2017-19. The experiment was executed in randomized block design with five and twelve treatments and four and three replications respectively. The five treatments consist of Control (i.e. Soil + FYM 3:1), Soil + FYM (1:1), Cocopeat (100%), Soil + Cocopeat (1:3), Soil+ FYM+ Rice Husk+ Cocopeat (1:1:1:1) and twelve treatments consist of December 2017, January 2018, February 2018, March 2018, April 2018, May 2018, June 2018, July 2018, August 2018, September 2018, October 2018 and November 2018. In this experiment survival, morphological attributes was observed periodically. The survival, morphological parameters such as plant height (cm), girth of graft (mm), length of new sprout (cm), number of leaves, leaf area (cm2), absolute growth rate (cm/ day), relative growth rate (cm/ cm/ day), root length (cm) and dry weight of root(g) were significantly influenced by different potting media. In potting medium, the highest survival percentage (93.00%) was observed in T5 i.e. soil + FYM + rice husk + cocopeat (1:1:1:1). The treatment T1 i.e. soil+ FYM (3:1) was recorded significant increase in plant height (57.98%) and relative growth rate (0.0064 cm/cm/day). T5 i.e. soil+ FYM+ rice husk+ cocopeat (1:1:1:1) was recorded significant increase in girth of grafts (11.64 mm) and new sprout length (34.80 cm). T2 i.e. soil+ FYM (1:1) was recorded significant increase in number of leaves (34.5), leaf area (9506.56 cm2) and highest absolute growth rate (0.1475 cm/day). Whereas, maximum root length (47.45 cm) and dry weight of root (23.20g) was obtained in treatment T5 i.e. soil + FYM + rice husk + cocopeat (1:1:1:1). In season of rebagging, the maximum survival percentage was recorded in T10 (96.00%) i.e. September 2018 followed by T3 (94.66 %) i.e. February 2018 whereas the maximum plant height percentage (39.14 %) in T5 i.e. April 2018, girth of graft (10.59 mm) in T8 i.e. June 2018, new sprout height (27.30 cm) in T4 i.e. March 2018. The number of leaves (30.33), leaf area (3766.7 cm2) highest relative growth rate (1.7429 cm/cm/day), highest absolute growth rate (0.2047 cm/day) and root length (49.00 cm) was observed in T3 i.e. February 2018. The treatment T10 i.e. September 2018 recorded maximum root dry weight (14.33g). Economics involved for different treatment showed that T5 i.e. soil+ FYM+ rice husk+ cocopeat (1:1:1:1) was promoting with highest net profit (Rs.1441.44) in potting medium. From the above investigation, it is concluded that potting mixture had significant effect on survival and growth of cashew grafts. The media containing cocopeat, FYM, soil along with rice husk was the ideal media for nursery, whereas the September and February was ideal months for cashew grafts rebagged in large sized polybags.
