    RESPONSE OF BABY CORN (ZEA MAYS L.) TO SOWING PERIODS AND CROP GEOMETRY.
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola., 2017-07-11) CHAMROY, THEMMEICHON.; Kale, Dr. V. S.
    An experiment entitled “Response of baby corn (Zea mays L.) to sowing periods and crop geometry” was carried out during 2013-14 and 2014-15 at Main Garden, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.). The experiment was laid out in factorial randomized block design with three replications and twenty treatment combinations with factor A i.e. four sowing periods; P1 (35th met. week; last week Aug.), P2 (39thmet. week; last week Sept.), P3 (43rd met. week; last week Oct.) and P4 (48th met. week; last week Nov.) and factor B i.e. five different crop geometry ; S1 (30cm × 30cm), S2 (45cm × 15cm), S3 (45cm × 30cm), S4 (60cm × 15cm) and S5 (60cm × 30cm). The different sowing periods were found to influence the growth, yield and quality of baby corn. Among all the sowing periods under study, P2 (39th met. week; last week Sept.) exhibited significantly the highest values of almost all the plant growth characteristics such as plant height (198.73 cm), number of leaves plant-1 (12.96), leaf area (509.28 cm2), LAI (3.49) and leaf chlorophyll content (1.95 mg g-1). However significantly, the minimum number of days to 50% cob emergence, 50% tasseling, 50% silking and harvest i.e. 48.77, 48.57, 51.82 and 52.4 days respectively was observed in the sowing period P1 (35th met. week last week Aug.). The yield and its attributing characters like cob length (10.96 cm), number of cobs plant-1 (2.96), cob weight with husk (49.76 g) and without husk (8.97), cob yield with husk(146.95 g) and without husk (26.43 g) plant-1, yield with husk (10.47 kg) and without husk (1.89 kg) plot-1, yield with husk (387.75 q) and without husk (70.13 q) hectare-1, fodder yield hectare-1 (36.24 t). However the treatment P3 (43rd met. week;last week Oct.) exhibited highest quality parameters; protein (17.37 %), fibre (5.57 %), total sugar (3.33 %) and reducing sugar (3.29 %) content as well as dry matter accumulation plant-1 (166.03 g). The crop geometry was also found to influence significantly the growth, yield and quality of baby corn. Most of the growth parameters such as number of leaves plant-1 (13.04), leaf area (511.76 cm2), leaf area index (3.56) and leaf chlorophyll content (2.34 mg g-1) were found maximum in crop geometry S3 (45 × 30 cm), which also shows the maximum cob length (11.04 cm), cob weight without husk (19.17 g) and all the quality parameters; protein (17.95 %), moisture (89.51 %), total sugar (3.36 %) and reducing sugar (3.32 %) content, while S1 (30 × 30 cm) recorded the highest fibre content (5.59 %). The dry matter accumulation plant-1 (172.89 g), No. of cobs plant-1(3.04), cob weight with husk (50.87 g), yield plant-1 with husk (155.13 g) and without husk (27.21 g) were obtained in the wider geometry S5 (60 × 30 cm). However, the closer geometry S2 (45 × 15 cm) gives highest plant height (199.44 cm), yield plot-1i.e. with husk (11.41 kg) and without husk (2.06 kg), yield hectare-1 i.e. with husk (422.74 q) and without husk (76.29 q) and fodder yield (40.44 t ha-1). Among the treatment combinations, it was observed that P2S3 (39th met. week; last week Sept. + 45 × 30 cm) exhibited highest values for almost all the growth parameters; number of leaves plant-1 (13.63), leaf area (512.62 cm2), LAI (3.62) and chlorophyll content (2.40 mg g-1). Whereas the treatment combination P2S2 (39th met. week; last week Sept. + 45 × 15 cm) gives highest plant height (205.47 cm). The yield and yield attributing characters such as, number of cobs plant-1(3.43), cob weight with husk (54.34 g) and cob yield plant-1with husk (186.53 g) and without husk (31.64 g) were found highest in P2S5 (39th met. week; last week Sept. + 60 × 30 cm). While the treatment combination P2S3 (39th met. week; last week Sept. + 45 × 30 cm) recorded maximum cob weight without husk (9.87 g) and cob length (11.32 cm). However, P2S2 (39th met. week; last week Sept. + 45 × 15 cm) exhibit highest fodder yield (40.85 t ha-1), yield plot-1; with husk (12.02 kg) and without husk (2.19 kg), yield hectare-1; with husk (445.01 q) and without husk (81.10 q).The treatment combination P2S2 (39th met. week; last week Sept. + 45 × 15 cm) obtained the highest gross monetary returns (Rs. 324997.03 ha-1), net returns (Rs.186640.51 ha-1) and B:C ratio (2.35).

    GENERATION MEAN ANALYSIS FOR YIELD AND ITS COMPONENT TRAITS IN BOTTLE GOURD.
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola., 2017-07-11) CHAUDHARI, GANESH VASUDEO.; Nagre, Dr. P. K.
    The investigation entitled, “Generation mean analysis for yield and its component traits in bottle gourd” was conducted at Main Garden, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.), India during summer 2012, summer 2013 and summer 2014 to know the heterosis and inbreeding depression, gene action and gene interactions, heritability and genetic advance in bottle gourd for sixteen characters viz., vine length, internodal length, node at which first female flower appeared, days to first female flower, sex ratio (M:F), fruit set (%), days to first fruit harvest, number of fruits/vine, average fruit weight, yield/vine, yield/hectare, fruit length, fruit diameter-pedicelar, fruit diameter-central, fruit diameter-stylar and number of seeds/fruit. The experimental material consisted of five genetically diverse parents viz., P1(Samrat), P2(Arka Bahar), P3(PSPL), P4(DBG-5) and P5(Pusa Samrudhi); their six F1S’ viz., cross C1(P1XP4), C2(P1XP5), C3 (P2XP4), C4(P2XP5), C5(P3XP4) and C6(P3XP5); their respective six F2s’ and back crosses in both directions (six BC1s and six BC2s) were evaluated in randomized block design with three replications using ‘Warad’ as a check. Parents P1(Samrat), P2(Arka Bahar), P4(DBG-5) and P5(Pusa Samrudhi) with superior per se performance contributed for improved hybrid vigour in their progeny. All the six crosses viz., C1(P1XP4), C2(P1XP5), C3(P2XP4), C4(P2XP5), C5(P3XP4) and C6(P3XP5) exhibited considerable heterosis over respective better parents. Cross C1(P1XP4) and C2(P1XP5) showed useful heterosis over check for yield and yield contributing traits along with excellent fruit characters. The segregating and backcross populations of these crosses found with reduced hybrid vigour and yield, which was evidence of non-additive gene action. Three parameter model was used to estimate gene effects where non-allelic gene interactions were found absent i.e. for internodal distance (in cross C1, C3 & C5), node at which first female flower appeared (in C3 & C4) and average fruit wt. (in C6). In rest of the characters of six crosses non-allelic gene interactions were present. In purview of gene action viz, additive, dominance and gene interactions like additive x additive and dominance x dominance, their magnitude differed significantly for studied characters in six crosses. Duplicate type of epistasis was prevalent whereas complimentary epistasis found for few characters like fruit length (in cross C1, C2, C4 & C6), and no. of seeds per fruit (in C6 & C2). In all the six crosses, the traits like, fruit set (%), no. of fruits/vine, average fruit wt., yield/vine and yield/ha showed strong inclination towards adoption of heterosis breeding for improvement. The character like days to first fruit harvest can be expoited using both heterosis breeding (in C1, C2, C3, C5 & C6) and synthetic varietal breeding (in C4) for early harvest. Heritability and genetic advance investigation revealed, non-additive gene effect for vine length, internodal distance, node at which first female flower appeared, yield/vine and yield/ha for which heterosis breeding can be taken up. Both additive as well as non-additive gene effects were present in equal proportion for characters viz., days to first female flower, fruit set % and days to first fruit harvest; selection as well as heterosis breeding for improvement of these characters may be considered.
