Abstract

The experiment was conducted during summer seasons of 2015 & 2016 at the Research Farm of Highland Agriculture Research and Extension Centre, Kukumseri, Lahaul-Spiti district of dry temperate zone of Himachal Pradesh. The study revealed that the tribal farmers of Lahaul & Spiti district of Himachal Pradesh can take Frenchbean seed production of 'PalamMriduala' cultivar by sowing the crop in north-south row direction (more seed yield by 15.7% & Rs 1,31,467 as net returns/ha) at row spacing of 30 cm (more seed yield 22.7% &Rs 1,41,404 as net returns/ha) and by applying 62.5 N, 125 kg P₂O₅ and 62.5 kg K₂O/ha (7.25 % more seed yield & Rs.1,31,467 as net returns/ha) as basal application to realize more productivity and profitability compared to sowing in east-west at 45 cm row spacing and 100 % of recommended dose of fertilizer.

Abstract

Turcicum leaf blight (TLB) and Maydis leaf blight (MLB) are amongst the important diseases of maize grown in the North-Western Himalayas. The experimental material was evaluated at two environments (natural E₁ & inoculated E₁) representing different agroclimatic and ecological conditions of North-Western Himalayas (SAREC, Kangra E₁ and HAREC, Bajaura E₁) to identify new resistance sources and to establish durability of known resistance sources of 8 parental genotypes, their 28 crosses and four checks viz., Palam Sankar Makka-2, Vivek Hybrid-45, Bio-9544 and DKC 7074 and were evaluated in RBD during Kharif, 2019 under natural conditions in E , whereas, under both natural as well as artificial epiphytotic conditions in E₁. The present study indicated the identification of 3 parental lines viz., P₃, P₆, P₄ cross combinations viz., P₃ × P₄, P₃ × P₅, P₃ × P₆, P₇ × P₈ and checks viz., Palam Sankar Makka-2, Vivek Hybrid-45 and DKC 7074 exhibiting resistant reaction against TLB in both environments under natural conditions and under artificial condition in E₁, whereas, against MLB under both natural as well as artificial epiphytotic condition in E₁. The new sources of resistance in the present study will be helpful for their deployment in the breeding programmes. The identified lines against TLB and MLB would serve as valuable sources of resistance and can be utilized in resistance breeding programmes. The cross combinations can be further evaluated for yield and other characters and can be released as promising hybrid varieties resistant to TLB and MLB.

Abstract

The experimental material consisted of 25 lines, 2 testers, their 50 crosses and two checks viz., Palam Sankar Makka-2 and PSCL 4640 were evaluated in RBD during Kharif 2020 against turcicum leaf blight (TLB), maydis leaf blight (MLB) and banded leaf and sheath blight (BLSB) under natural epiphytotic conditions at SAREC, Kangra. Among lines, 14 showed resistant to BLSB and 15 were resistant to TLB. 18 lines were moderately resistant to MLB. Three crosses viz., L₃ × T₁ , L₂₄ × T₂ and L₂₅ × T₁ exhibited resistant towards BLSB, MLB and TLB. The cross combinations can be further evaluated for yield and other characters and released as promising hybrids resistant to TLB, MLB and BLSB.

Abstract

A field experiment was conducted under All India Coordinated Research Project on Rapeseed-Mustard at CSK HPKV, Shivalik Agriculture Research and Extension Centre, Kangra in rabi 2019-20. The experiment comprised of one test genotype of gobhi sarson ‘AKMS 8141’and three checks, viz., GSL1, Kranti & GSC 6 in main plots and three fertility levels viz., 100, 125 & 150 % RDF (recommended dose of fertilizers ) in subplots were tested in split plot design. The test genotype ‘AKMS 8141’(193 cm) was significantly taller than Kranti by 12 cm and GSC 6 by 38 cm. Significantly more seed yield was recorded by the test genotype ‘AKMS 8141" (1260 kg/ha) being at par with GSC 6 (1249 kg/ha) compared to GSL 1 (996 kg/ha) and Kranti (910 kg/ha) attributed to the higher value of siliquae perplant (366), seeds per siliqua (23.8) and test weight (3.28g). The test genotype ‘AKMS 8141’ having seed oil content of 40.8%, resulted in oil productivity 514.4 kg/ha on par with GSC 6. Significant variation in seed and oil yield was not recorded due to varying fertility level. Thus, it may be concluded that the new genotype of gobhi sarson ‘AKMS 8141’is productive and profitable and may be grown by the farmers of mid hills of Himachal Pradesh.
