    Effect of Staggered Sowing and Spacing on Growth, Yield and Quality of Carrot (Daucus carota L.) Varieties in Arid Region of Rajasthan
    (Agriculture University, Jodhpur, 2019-05-28) Somveer; Choudhary, Santosh; Moond, S.K.; Raiger, P.R.
    A field experiment was conducted at College of Agriculture, Mandor, Jodhpur during the Kharif season of 2018, to find out the suitable variety and its optimum sowing time and spacing for higher yield, quality and net returns of carrot in western Rajasthan. The treatments comprising two varieties (‘Pusa Rudhira’ and ‘Pusa Vrishti’), three spacing (20 cm × 10 cm, 30 cm × 10 cm and 30 cm × 20 cm) and four dates of sowing (10th August, 25th August, 10th September and 25th September) allocated in Factorial Randomized Block Design with three replications. Experiment results revealed that variety ‘Pusa Vrishti’ recorded significantly higher growth parameters while ‘Pusa Rudhira’ recorded significantly higher yield parameters, root yield (23.8 t ha-1), quality parameters and net returns (Rs. 2,55,491) with lesser days to marketable maturity (73.9). Among different spacing, significantly higher growth and yield parameters were observed in widest spacing (30 cm × 20 cm). However, root yield (24.5 t ha-1) and net returns (Rs.2,26,604) were recorded highest in S1 (20 cm × 10 cm). The 25th September sowing recorded significantly highest growth parameters, yield parameters, yield (25.8 t ha-1) and quality parameters besides being earliness in term of maturity (73.7 days). However, the highest net returns (Rs. 3,09,028) and B:C ratio (4.33) were recorded in 10th August sowing. The combination of ‘Pusa Vrishti’ sown on 25th September, recorded highest plant height at 60 DAS (39.3 cm) and fresh weight of aerial part (101.9 g) whereas, ‘Pusa Rudhira’ sown on 25th September combination recorded significantly higher values of fresh weight of root (139.4 g), root yield (11.1 kg plot-1) and root yield (25.8 t ha-1). Hence, variety ‘Pusa Rudhira’ sown in closer spacing of 20 cm × 10 cm spacing under staggered sowing is found to be superior in terms of yield, quality, earliness and net returns in the arid regions of Rajasthan.

    (Agriculture University, Jodhpur, 2019-07-01) Sirohi, Sushila; Kumhar, S. R.; Choudhary, B.R.; Ram, Moola
    An experiment entitled “Heterosis and combining ability studies in sesame (Sesamum indicum L.)” was carried out during kharif season of 2018 at research farm of Agricultural Research Station, Mandor, Jodhpur. The experiment comprised of twelve parents, their twenty seven crosses and one check, was shown in randomized block design with three replications. The analysis of variance for all the characters revealed that genotypes, parents and hybrids showed significant differences for most of characters expect oil content for parents indicating the presence of sufficient variability in the study material. On the basis per se performance, parents viz., RT-54, RT-103, RT-371 and RT-372 were found promising and crosses viz., RT-351 × TKG-22, RT-351 × RT-377 and RT-54 × TKG-22 were revealed better performance for seed yield per plant. Cross, RT-351 × TKG-22 depicted the highest heterosis, heterobeltiosis and standard heterosis. In combining ability analysis, the extent of GCA variance was lower than SCA variance for most of the characters demonstrating the predominance of non additive gene action except oil content. Based on gca effects, TKG-22, GT-10 and RT-372 were good general combiner for seed yield and some of the component characters. Crosses, RT-351 × TKG-22 and RT-54 × RT-372 were most promising hybrids for seed yield and these crosses involved average × good and average × average parents and could be exploited for heterosis breeding or to produce for desirable segregants for sesame crop improvement.

    Genetic Variability and Divergence Study for Seed Yield and it’s Components in Pearl Millet [Pennisetum glaucum (L.) R. Br.]
    (Agriculture University, Jodhpur, 2019-05-24) Yadav, Shankar Lal; Rajpurohit, B.S.; Choudhary, B.R.; Choudhary, Santosh
    An experiment entitled “Genetic Variability and Divergence Study for Seed Yield and it’s Components in Pearl Millet [Pennisetum glaucum (L.) R. Br.]” was carried out during Kharif 2018 at the Research Farm of Project Coordinating Unit, AICRP on Pearl Millet, Mandor, Jodhpur. The experiment was laid out in Randomized Block Design (RBD) with 30 genotypes and three replications to estimate the extent of genetic variability, heritability, genetic advance, correlation coefficient, path coefficient analysis and genetic divergence among all the genotypes. Analysis of variance showed highly significant variance among the genotypes for all the characters, under study, indicated availability of wide spectrum of variability among the genotypes. The phenotypic coefficient of variation (PCV) was slightly higher than the respective genotypic coefficient of variation (GCV) for all the characters under study indicated less influence of environment on the genotypes in expression of traits. Highest magnitudes of PCV and GCV were observed for zinc content whereas, the lowest PCV and GCV were observed for days to maturity. High estimate of heritability along with high genetic advance as percentage of mean were observed for days to 50% flowering, plant height, number of productive tillers per plant, panicle length, panicle diameter, stover yield per plant, grain yield per plant, 1000 grain weight, harvest index, iron content and zinc content indicated role of additive gene action for expression of these characters and are proven important for improving seed yield. High heritability values with moderate genetic advance as percentage of mean were observed for days to maturity and protein content. The grain yield per plant was found positively correlated with plant height, panicle diameter, stover yield per plant, 1000 grain weight and harvest index which showed that these traits are may be the selection criteria in breeding programme for improvement of seed yield. Path coefficient analysis revealed that stover yield per plant, harvest index, plant height and 1000 grain weight were the important characters for selection of high yielding accessions as they exerted high positive direct effect as well as showed positive significant correlation with grain yield per plant. Based upon the genetic variability, heritability, genetic advance as percentage of mean, correlation and path analysis it was concluded that stover yield per plant, grain yield per plant, harvest index, number of productive tillers per plant, panicle diameter and panicle length are most important yield components in pearl millet breeding programme. Based on the relative magnitude of D2 values resulted through Tocher’s method the genotypes were grouped in six clusters. Out of six clusters, cluster I was the largest comprising of 25 genotypes followed by mono genotypic cluster II, III, IV, V and VI. This suggested the existence of high degree of diversity among the genotypes. The trait iron content contributed maximum towards genetic divergence. The intra cluster distance was recorded in cluster I. The inter cluster distance was highest between cluster IV and VI followed by cluster V and VI, and III and VI indicated that superior recombinants can be achieved by crossing between the genotypes RIB-17/009 x RIB-15177, J-2405 x RIB-15177 and RIB-335/04 x RIB 15177 in a definite fashion.

    Genetic Variability, Correlation and Path Analysis in Sesame (Sesamum indicum L.)
    (Agriculture University, Jodhpur, 2019-06-26) Kumari, Babita; Kumhar, S.R.; Rajpurohit, B.S.; Raiger, P.R.
    An experiment entitled “Genetic Variability, Correlation and Path Analysis in sesame (Sesamum indicum L.)” was carried out during kharif 2018-19 at the Research Farm of Agricultural Research Station, Mandor, Jodhpur (Rajasthan). The experiment was laid out using Randomized Block Design with forty genotypes in three replications to estimate the extent of genetic variability, heritability, genetic advance, correlation between yield and other characters and the direct and indirect effect of yield contributing traits through path coefficient analysis. Analysis of variance exhibited significant difference for all the characters suggesting the presence of great genetic variations among the genotypes studied. The phenotypic coefficient of variation (PCV) was slightly higher than the respective genotypic coefficient of variation (GCV) for all the characters, indicating less environmental influence on the genotypes. The highest magnitudes of PCV and GCV were observed for number of primary branches per plant whereas, the lowest was for days to maturity. Days to 50% flowering, days to maturity, number of primary branches per plant and seed yield per plant showed high estimates of heritability. High heritability coupled with high genetic advance as per cent of mean were altogether at a glance, observed for the traits like number of primary branches per plant and seed yield per plant suggesting additive gene action for expression of these characters. Hence, these characters may be proved as effective criteria for selection to improve seed yield in sesame. Correlation studies among the characters revealed that seed yield per plant had a highly positive and significant association with characters viz., number of primary branches per plant, number of capsules per plant, capsule bearing length and harvest index both at phenotypic and genotypic levels, therefore, selection for these characters may bring simultaneous improvement in the seed yield. Path coefficient analysis revealed that the highest positive direct effect on seed yield per plant exhibited by number of capsules per plant followed by capsule bearing length, harvest index, number of primary branches per plant, 1000 seed weight, plant height and days to 50% flowering, therefore, these traits may be used for further improvement in seed yield of sesame. Out of 40 genotypes EC-370867, IC-203936, RMT-251, IC-204531, RMT 244 and IC-203983 were found promising in seed yield and other characters. Hence, these genotypes would be used as parental source for future breeding programme.

    (Agriculture University, Jodhpur, 2019-06-19) Mandiwal, Mukesh; Shukla, U. N.; Mehriya, M. L.; Raiger, P. R.
    A field experiment entitled “Effect of phosphorus and biofertilizers on growth and yield of mungbean [Vigna radiata (L.) Wilczek]” was conducted at Agricultural Research Station, Mandor, Jodhpur during kharif season of 2018. A field experiment was laid out in randomized block design (RBD) with nine treatments and replicated thrice. The treatments taken in the investigation were Control (F0), 20 kg P2O5 ha-1 (F1), 40 kg P2O5 ha-1 (F2), 20 kg P2O5 ha-1 + PSB (F3), 40 kg P2O5 ha-1 + PSB (F4), 20 kg P2O5 ha-1 + Aspergillus awamori (F5), 40 kg P2O5 ha-1 + Aspergillus awamori (F6), 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7) and 40 kg P2O5 ha-1 + PSB + Aspergillus awamori (F8). According to treatments, seeds of mungbean were inoculated with PSB + Aspergillus awamori, while different doses of phosphorus were applied in the soil. Among growth attributes viz. plant height (14.73, 46.08 and 49.48 cm), dry matter accumulation plant-1 (3.02, 21.45 and 24.63 g) at 30, 60 DAS and at harvest, respectively, while final plant population (3.29 lakh ha-1), number of branches plant-1 (7.81) as well as yield attributing characters viz. number of pods plant-1 (48.34), seeds pod-1 (12.57) and 1000-seeds weight (44.66 g) resulted in higher seed yield (1583 kg ha-1) and stover yield (3504 kg ha-1) were recorded significantly under treatment applied with 40 kg P2O5 ha-1 + PSB + Aspergillus awamori (F8) followed by 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7). However, 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7) and 40 kg P2O5 ha-1 + Aspergillus awamori (F6) were statistically at par with each others with respect to growth attributes, yield attributes and yield of mungbean.Similarly, integrated application of 40 kg P2O5 ha-1 + PSB + Aspergillus awamori (F8) recorded significantly higher phosphorus content in seeds (0.477%) and stover (0.273%) results in higher uptake of phosphorus by seeds (7.56 kg ha-1) and stover (9.56 kg ha-1) of mungbean and showed significant superiority over rest of the treatments. However, 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7) and 40 kg P2O5 ha-1 + Aspergillus awamori (F6) were statistically at par with each others with respect to phosphorus content and uptake by seeds and stover. Increase in seed and stover yield, which subsequently improved gross returns ( 1,31,440 and 1,20,787 ha-1), net returns ( 1,08,671 and 98,960 ha-1 ) and B: C ratio (5.77 and 5.53 ) and recorded highest under 40 kg P2O5 ha-1 + PSB + Aspergillus awamori (F8) followed by 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7), respectively

    (Agriculture University, Jodhpur, 2019-07-26) BORANA, HITESH; Singh, Ishwar; Ram, Moola; Shukla, U.N.
    A field experiment was conducted at Agricultural Research Station, Mandor, Agriculture University, Jodhpur during kharif season of 2018 to study the “Effect of Weed Management Practices on Growth and Yield of Clusterbean [Cyamopsis tetragonoloba (L.) Taub]”. The Field experiment was laid out in randomized block design (RBD) with ten treatments of replicated thrice. The treatments comprises of W1-Weedy Check, W2-Weed free, W3-Pendimethalin 750 g ha-1 (PE), W4- Imazethapyr 40 g ha-1 (Early post-emergence), W5-Pendimethalin + imazethapyr 750 g ha-1 (PE), W6-Imazethapyr + imazamox 50 g ha-1 (Early post-emergence), W7- Pendimethalin 750 g ha-1 (PE) + one hand weeding at 25 DAS, W8-Imazethapyr 40 g ha-1 (Early post-emergence) + one hand weeding at 35 DAS, W9-Pendimethalin + imazethapyr 750 g ha-1 (PE) + one hand weeding at 25 DAS, W10-Imazethapyr + imazamox 50 g ha-1 (Early post-emergence) + one hand weeding at 35 DAS. According to treatments, pendimethalin and its ready mix with imazethapyr was applied as pre-mergence (within 2 DAS), while imazethapyr and its ready mix with imazamox was applied as early post-emergence (20 DAS). Among treatments, application of imazethapyr + imazamox 50 g ha-1 (early post-emergence) + one hand weeding at 35 DAS significantly reduced weed density of narrow and broad-leaved weeds and weed dry matter at 40, 60, 80 DAS and at harvest however, it was found at par with imazethapyr 40 g ha-1 (early post emergence) + one hand weeding at 35 DAS. Similarly, higher weed control efficiency was also obtained under these treatments which resulted in reduction of weed index as well.The plant height, no. of branches plant-1, dry matter accumulation (g plant-1) as well as yield attributing characters viz., no. of pods plant-1, no. of seeds pod-1 and 1000-seed weight of clusterbean were produced significantly higher under application of imazethapyr + imazamox 50 g ha-1 (early post-emergence) + one hand weeding at 35 DAS. Due to better growth, higher number of yield attributes and less weed index, this treatment resulted in maximum seed yield of 1180 kg ha-1 which was statistically at par with weed free season long plot (1237 kg ha-1). Application of imazethapyr 40 g ha-1 (early post-emergence) + one hand weeding at 35 DAS produced seed yield of 1120 kg ha-1 which was statistically at par with imazethapyr + imazamox 50 g ha-1 (early post-emergence) + one hand weeding at 35 DAS (1180 kg ha-1). The highest amount of total nitrogen uptake by crop (112.1 kg ha-1) was recorded with weed free treatment which remained at par with imazethapyr + imazamox 50 g ha-1 + one hand weeding at 35 DAS (106.5 kg ha-1). The lowest amount of nitrogen removal by weeds (22 kg ha-1) was obtained with the application of imazethapyr + imazamox 50 g ha-1 + one hand weeding at 35 DAS followed by imazethapyr 40 g ha-1 + one hand weeding at 35 DAS. The highest net monetary return and B:C ratio of 49,693 and 3.23 were obtained with imazethapyr + imazamox 50 g ha-1 (early post-emergence) + one hand weeding at 35 DAS, respectively followed by imazethapyr 40 g ha-1 (early post emergence) + one hand weeding at 35 DAS.

    Effect of Zinc and Iron Application on Growth and Yield of Mungbean [Vigna radiata (L.) Wilczek]
    (Agriculture University, Jodhpur, 2019-06-19) Gehlot, Navratan; Ram, Moola; Choudhary, B.R.; Raiger, P.R.
    Field experiment was conducted at Agricultural Research Station, Mandor, Agriculture University, Jodhpur during kharif season of 2018 on sandy loam soil of low nitrogen, phosphorus, zinc and iron and medium potassium content with 7.8 pH of soil. The experiment was laid out in randomized block design (RBD) with 3 replications. The treatments comprised of T1- RDF (common to all treatments), T2- Soil application of zinc sulphate at 25 kg/ha, T3- Foliar application of zinc sulphate at 0.5% at 35 DAS, T4 = (T2+T3), T5- Soil application of ferrous sulphate at 25 kg/ha, T6- Foliar application of ferrous sulphate at 0.5% at 35 DAS, T7 = (T5+T6), T8- Soil application of zinc sulphate and ferrous sulphate each at 25 kg/ha, T9 = (T8+T3), T10 = (T8+T6). The results in terms of plant height, dry matter accumulation, number of branches/plant, number of pods/plant, number of seed/pod, test weight, seed and stover yield of mungbean increased significantly due to soil application of zinc sulphate and ferrous sulphate each at 25 kg/ha (T8) over control. The maximum increment in the growth and yield attributes were due to application of T10 followed by T9 but these were statistically at par with T8. The significantly higher seed yield (1323 kg/ha) and higher net returns ( 83,128/ha) was recorded with application of T8 which was further increased due to T9 and T10 but BC ratio remained highest (4.52) with T8. Therefore, it was concluded that soil application of zinc sulphate and ferrous sulphate each at 25 kg/ha can be used for higher grain yield, net return and BC ratio of mungbean in western Rajasthan conditions. These results are based on one year experiment hence requires validation through further experiments to formulate recommendation.
