WATER ECONOMIZATION IN RICE THROUGH MICROBIAL DECOMPOSITION OF RICE STRAW

Paper ID- AMA-25-06-2023-12367

Non-scientific use of rice straw causes environmental pollution and releases greenhouse gases to the atmosphere. The aim of this study was to enhance water productivity by recycling this huge amount of agricultural biomass by degrading it through microbial inoculants. The present study consists of three irrigation and seven nutrient management treatments viz., Continuous flooding (CON), Flooding with early and mid season drying (EMD), Irrigation as per SRI system (SRI) were assigned to main plot. Whereas, Nutrient management (NM) viz., Rice raw straw incorporation + 100% RDF (SF1), Rice raw straw incorporation + 75% RDF + 2% Urea foliar spray (twice) (SF2), Rice raw straw incorporation with Pusa Decomposer Capsules + 100% RDF (SF1D), Rice raw straw incorporation with Pusa Decomposer Capsules + 75% RDF + 2% Urea foliar spray (twice) (SF2D), Rice raw straw incorporation with TNAU Biomineralizer + 100% RDF (SF1B), Rice raw straw incorporation with TNAU Biomineralizer + 75% RDF + 2% Urea foliar spray (twice) (SF2B), 100% RDF (F1) were allocated to sub-plot. The outcome of the study revealed that irrigation as per SRI system (SRI) significantly recorded higher WUE of 7.32 kg ha-1 mm-1 in kharif 2021 and 6.35 kg ha-1 mm-1 in summer 2022. Concerning nutrient management practices, rice raw straw incorporation with pusa decomposer capsules + 100% RDF (SF1D) recorded marked influence with the highest WUE of 6.46 in kharif 2021 and 5.41 kg ha-1 mm-1 in summer 2022.

Generation mean analysis of yield and quality traits in carrot (Daucus carota L.)

Paper ID- AMA-25-06-2023-12366

Carrot is important root vegetable being used as raw and cooked form (gajar halwa). The root is main edible part, breeding should be focus on traits that can increase root production. The productivity of carrot depends upon the cultivar and its yield contributing characters. Information of the genetics analysis of yield traits is essential for developing new breeding lines which can contribute to improvement of specific traits. The production should be based on yield contributing traits like plant height, number of leaves, leaf length, root length, root diameter, core diameter, root weight, TSS, yield per plant, root fresh weight and root dry weight. As a result, the findings aid in the production of carrot hybrids or cultivars. Genetic analysis of yield traits of carrot was estimated through three cross combinations, and the results revealed the existence of additive [d], dominance [h], additive x additive [i], additive x dominance [j] and dominance x dominance [l] gene actions. In most cases, duplicate epistasis was seen for traits such as plant height, number of leaves, leaf length, core diameter, TSS, root fresh weight, and root dry weight. The presence of additive, dominance, additive, and dominance interaction effects was indicated by similar signs of (h) and (l) for the expression of root length, root diameter, root weight, and yield per plant, indicating the presence of additive, dominance, additive, and dominance interaction effects. The complementary type showed that these traits might have a significant degree of heterosis, and that recurrent selection could be employed to improve these traits in future generations.

Propagation Studies in Jamun [Syzygium cumini (L.) Skeels] under Rainfed Conditions

Paper ID- AMA-24-06-2023-12364

Investigation on propagation of jamun under rainfed conditions of Jammu sub-tropics was carried out in the year 2019-20, with four different methods i.e. T-budding, patch budding, tongue grafting and wedge grafting during three different timings viz. 4th week of July, 2nd week of August and 4th week of August under open field conditions. The results of the study indicated that among various methods and different timings of propagation, significantly minimum days taken to bud sprouting (16.45 days) were observed in wedge grafting performed during 4th week of July. Whereas, higher length in scion wood (39.90 cm), per cent sprouting (64.00 %) and success (59.66 %) was observed in wedge grafting during 2nd week of August. After 180 days of jamun propagation, maximum number of shoots (9.47) shoot length (49.68 cm), average leaf area (20.76 cm2) and plant height (89.70 cm) were recorded in wedge grafting performed during 2nd week of August, while, maximum stock-scion ratio was observed as 1.95 in patch budding performed during 2nd week of August.

Organic amendments and nitrogen levels effects on soil health and productivity of rice-wheat cropping system in North western India

Paper ID- AMA-23-06-2023-12362

Soil fertility is at risk in intensive cropping systems when using an exclusive regime of inorganic fertilisers without returning sufficient organic matter to the soil. Our objective was to evaluate the effects of organic amendments interacting with different rates of inorganic nitrogen fertiliser on crop yields of rice and wheat. Yield data from rice and wheat were collected for two seasons between 2018 and 2020 from a continuous field trial based at PAU, Ludhiana and Research station, Dyal Bharang, Amritsar in split plot design. Main plot consisted of four treatments (green manuring, farmyard manure, poultry manure and control) and four subplot treatments (Control, 50 kg N ha-1,75 kg N ha-1 and 100 kg N ha-1) replicated four times in rice crop and its residual effect was studied in wheat. Results revealed that rice-wheat productivity, plant growth, yield attributes and soil nutrients availability increased significantly (p<0.05) with the application of organic amendments at different nitrogen levels. Application of poultry manure in rice helped to increase grain yield over the other amendments and recorded 67.3 % and 61.4 % higher grain yield than control in both the years. The residual effect of poultry manure was also evident in subsequent wheat crop. It could be concluded that application of poultry manure along with 100 kg N ha-1 or 75 kg N ha-1 recorded similar yield, it implies that even lower dose could be sufficient for rice crop as well as following wheat crop to obtain higher yield.

Studies on response to day length extension on growth and flowering in spray chrysanthemum (Chrysanthemum morifolium Ramat).

Paper ID- AMA-23-06-2023-12361

This research were conducted to study the effect of different photoperiod in chrysanthemum cv. Autumn white and Diana orange for the period of 1st October 2021 to 20th March 2023 in climate controlled greenhouse at Centre for Protected Cultivation Technology (CPCT), IARI, New Delhi. Two spray Chrysanthemum varieties such as Autumn white and Diana Orange was exposed to 3 various day length extension treatments under semi climate controlled green house with use of Incandescent lamps for 10, 15 and 20 days duration and each 4 replications. Various observation in respect to growth and flowering were recorded at different intervals (0,15, 30,45 and 60 days). Vegetative growth parameters like plant height (95.79 cm), stem diameter (6.56 mm), inter nodal length (4.41cm), total number of leaves (39), leaf area (262.52 cm2), leaf area index(3.22), leaf fresh (24.91g) and dry weight(2.61 g), stem fresh (21.88g) and dry weight (3.23g) were measured and maximum under 20 days extended day length at 60 days after planting. Flowering parameters like bud diameter (16.78 mm), flower diameter (87.68 mm), time taken for flower bud induction(89.3days), time taken for flower opening (100.7 days), flower fresh(13.57g) and dry weight (1.59g) were taken at different blooming time intervals and highest were found in Autumn white at 60 days after planting for 20 days. Among two different varieties Autumn white showed significant difference than Diana orange.
