Daily maximum and minimum temperatures of 4 stations and rainfall of 22 stations of Himachal Pradesh for the period of 1970 to 2014 have been used to work out extreme climate indices and trends. The temperature and rainfall indices for different stations studied showed no uniform trend. The results indicated the increasing trend in minimum of maximum and minimum of minimum temperature. The increased frequency of warm nights and warm spell but decrease in the number of hot days and hot nights were observed at Bajaura and Shimla. The maximum one day rainfall amount, maximum 5-day rainfall during the month and very wet days were found to decrease at most of the stations in the state. Consecutive wet days (CW D) and annual total rainy days (PRCPTOT) showed statistically mixed trends at various stations in the state. © 2017, Association of Agrometeorologists. All rights reserved.

A field experiment was conducted during 2012–13 and 2013–14 on a silty clay-loam soil of Palampur, Himachal Pradesh, to study the productivity and economics of wheat [Triticum aestivum (L.) emend. Fiori & Paol.]+ chickpea (Cicer arietinum L.) intercropping under irrigation and nutrient management. Growth, yield attributes, grain and straw yields of wheat and chickpea were affected significantly with irrigation and nutrient-management practices. The irrigated condition resulted in higher wheat-equivalent yield and benefit: cost ratio over rainfed condition. Integrated nutrient management (INM), being statistically at par with organic nutrient management, recorded the highest wheat-equivalent yield over inorganic nutrient management and farmer’s practice. Organic nutrient management recorded higher net returns (32.6 × 103/ha), whereas INM recorded higher benefit: cost ratio (1.92). Higher values of available nitrogen (215.3 kg/ha), phosphorus (37.1 kg/ha) and potassium (177.3 kg/ha) in soil were recorded in INM than the other nutrient-management practices. © 2017, Indian Society of Agronomy.

On-farm experiment was conducted in sub-montane and low hills sub-tropical zone of Himachal Pradesh to study the impact of application of recommended dose of nutrients and full package of practices with and without farm yard manure (FYM) along with farmers' practice in rice-wheat cropping sequence under irrigated conditions for four consecutive cropping seasons during 2007-08 to 2010-11. The single intervention of applying recommended fertilizer nutrients over the existing farmer's practice increased the overall grain yields of rice and wheat by about 18.1 and 21.9%, respectively. The application of recommended package of practices further increased rice and wheat yields by about 8.1 and 10.2%, respectively and rice grain equivalent yield and net returns by about 30.4 & 40% over the fanner's practice. Both crops also responded to the application of FYM which significantly increased rice and wheat grain and straw yields, rice grain equivalent yield and gross and net returns over the other treatments.

A field experiment was conducted on a silty clay loam soil of Palampur during 2009–2011, to study effect of tillage and planting-management techniques in maize (Zea mays L.)–wheat {Triticum aestivum (L.) emend. Fiori & Paol.} cropping system. Zero tillage in rainy (kharif) and winter (rabi) seasons resulted comparable yield as with multi-crop planter, manual seed drill and conventional tillage methods. However, multi-crop planter and manual seed drill in the rainy season produced significantly higher effective plants/m2 of maize (8.0 and 7.8, respectively). In case of wheat, conventional tillage in the rainy season produced significantly the highest effective spikes/m2 (322.6) over the other treatments. However, multi-crop planter in the winter season produced significantly the highest effective spikes/m2 (337.6). Water productivity in the rainy season was minimum under zero tillage {41.3 kg maize grain equivalent yield (MEY)/ha-mm} and maximum under manual seed drill {48.5 kg (MEY)/ha-mm}, while water use was the lowest under manual seed drill and the maximum under zero tillage. System’s total energy output was the highest with conventional tillage in the rainy season and multi-crop planter in the winter season. In maize crop, manual seed drill and multi-crop planter in the rainy season produced significantly lower total weed count at 60 days after sowing (DAS). Similarly, the total weed dry weight at 90 DAS was lowest under manual seed drill. In wheat crop, multi-crop planter, manual seed drill and conventional tillage in the winter season produced significantly lower weed count (at 30 and 60 DAS, respectively) compared to zero tillage. Seeding with zero tillage, multi-crop planter and manual seed drill in the rainy season and the winter season could save 9, 11.5 and 6 mandays and 22, 16 and 9 man-days, respectively, over the conventional tillage. © 2014, Indian Society of Agronomy.

A field investigation was carried out during rabi seasons of 2012 and 2013 at Palampur with nine treatments comprising three doses of metsulfuron methyl (2, 4 and 8 g/ha), two doses of clodinafop (60 and 120 g/ha), two combinations i. e. clodinafop+metsulfuron methyl 60+4 g/ha and isoproturon+2,4-D 1.0+0.5 kg/ha and weedy check to evaluate their performance against mixed weed flora in wheat. Experimental field was mostly infested with grassy weeds with Phalaris minor as the most dominant weed constituting 48.03% of total weed flora. Lolium temulentum, Avena fatua and Vicia sativa were the other important weeds. Among different herbicides, clodinafop 120 g/ha being statistically alike with its lower dose i. e 60 g/ha resulted in significantly lower count of grassy weeds viz., P. minor, L. temulentum, A. fatua at 90 and 120 DAS. Combination of clodinafop+ metsulfuron methyl 60+4 g/ha was the next best in this regard. Same herbicide i. e. clodinafop120 g/ha recorded significantly lower dry matter of all these grassy weeds at both the stages of observation. However, clodinafop+metsulfuron methyl 60+4 g/ha was at par with it for reducing the dry matter of A. fatua at both the stages of observation and P. minor and L. temulentum at 120 DAS and also with clodinafop 60 g/ha for L. temulentum at both stages and for A. ludoviciana and P. minor at 90 and 120 DAS, respectively. Among different herbicides, tank mix application of clodinafop+metsulfuron methyl 60+4 g/ha and isoproturon+2,4-D 1.0+0.5 kg/ha being at par with metsulfuron methyl 4 and 8 g/ha resulted in recording significantly lower weed count and dry matter of V. sativa and Anagallis arvensis at both stages of observation. Similarly, both these tank mixtures at both the stages and clodinafop 60 and 120 g/ha at 120 DAS being at par with each other were significantly superior for controlling other weeds. Tank mix application of clodinafop+metsulfuron methyl 60+4 g/ha being at par with clodinafop 60 and 120 g/ha resulted in recording significantly lower weed count and weed dry matter of total weeds. Clodinafop applied at either 60 or 120 g/ha being at par with both combinations of herbicides i. e. clodinafop+metsulfuron methyl 60+4 g/ha and isoproturon+2,4-D 1.0+0.5 kg/ha produced significantly higher grain, straw and biological yield of wheat. Clodinafop 60 g/ha was the best in recording highest net returns of Rs. 29385/ha with B : C ratio of 1.21, followed by clodinafop+metsulfuron methyl 60+4 g/ ha and isoproturon+2, 4-D 1.0+0.5 kg/ha having net returns of Rs. 29364 and 28386/ ha, respectively, with similar B : C ratio of 1.19.

Diversification and intensification of existing maize-wheat cropping system on small, undulating and marginal farmer's field with suitable resource conserving practices is the key answer for increasing the profitability of hill farmers. Keeping this in view, an experiment with two tillage methods viz., zero tillage and conventional tillage, three cropping systems viz., maize-wheat, baby corn+frenchbean-pea-summer squash and maize+soybeangobhi sarson+toria, two mulch treatments viz., no mulch and crop residue mulch, and two fertilizer treatments viz., recommended dose of fertilizers and 75% RDF+25% N through FYM was conducted at Palampur during kharif 2012-rabi 2014. The results showed that conventional tillage produced significantly higher maize grain equivalent yield [MGEY (11.2%)], production efficiency (13.9%), productivity of the system (11.2%), net returns (17.3%) and B: C ratio (12.4%) over zero tillage. Replacing traditional maize-wheat with baby corn+frenchbean-pea-summer squash increased MGEY (190.8%), production efficiency (190.5%), productivity of the system (182.1%), gross returns (121.0%), net returns (176.4%), B: C ratio (64.1%) and profitability of the system (176.4%). Application of mulch significantly increased MGEY by 7.4% as compared to no mulch. Similarly, integrated nutrient management also signifcantly inceased MGEY by 4.3% over recommended dose of fertilizers.

Effect of nitrogen substitution through different organics on yield, uptake and available nutrients in a rice- wheat system was studied after 17 and 18th cropping cycles. Nitrogen substitution through different organics increased significantly the productivity and NPK uptake by rice and wheat. Grain yield of rice, wheat and that of the system increased significantly with the increasing levels of NPK. The maximum yield of rice (3.62 t ha-1) and that of the system (7.04 t ha-1 in terms of rice grain equivalent) was recorded under T5 (50% NPK along with 50% N through FYM during kharif followed by 100% NPK during rabi), while wheat grain yield was maximum (3.20 t ha-1) in T4(100% NPK to both the crops). The total uptake of N, P and K by rice-wheat system was also highest in T5. Though the chemical sources of nutrients increased crop yields over control, these failed to improve the soil properties vis-a-vis combined use of the organics and inorganics. The improvement of soil fertility with respect to available macronutrients and micronutrient cations was also prominent with the application of 50% NPK + 50% N through FYM in kharif followed by 100% NPK in rabi.

The field experiment was conducted during Rabi 2010-11 at Palampur with five varieties (HS-490, VL-804, VL-829, VL-892 and VL-907) and four dates of sowing (5th November, 20th November, 5th December and 20th December) in split plot design with three replications. The sowing beyond 20th November up to 20th December resulted in significant reduction in yield. The decrease in grain yield over 20th November date of sowing was 12.9 per cent due to rise in maximum and minimum temperature by 4.0 and 2.2 °C during reproductive phase and 0.7 and 0.8 °C during maturity phase when the crop was sown on 5th December. The comparative reduction in 20th December date of sowing was much higher (22.6 %) when the crop experienced higher maximum and minimum temperature by 4.7 and 2.5 °C during reproductive phase and 1.4 and 1.8 °C during maturity phase. Among all varieties, HS-490, VL-892 and VL-907 recorded significantly higher grain yield on 20th November sowing and remained at par with 5th November sowing. Variety VL-804 and VL-829 produced significantly higher grain yield on 5th November sowing and remained at par with 20th November sowing. Copyright © EM International.

The present investigation was carried out to study the effect of integrated nutrient management on rice yield and sulphur transformation in soil into its various chemical pools in an on-going long-term fertilizer experiment initiated during kharif 1991 at research farm of CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur. Nine treatments comprising control, inorganics viz., 50 and 100% NPK and conjoint use of 50 and 75% NPK with 50 and 25% N substitution either through FYM, wheat straw or green manure, Sesbania aculeata (Dhaincha) to rice (June-October) followed by 100 and 75% NPK through inorganics to wheat (November-May), respectively, were imposed since the inception of the experiment. Different S fractions were estimated in surface soil samples after the harvest of wheat (June, 2011). Data in respect of grain and straw yield of rice and different soil properties were also recorded for two years (2010 and 2011). The results of surface soil samples (0-0.15 m) collected after the harvest of wheat showed that zero fertilization led to decline in the levels of all the S forms, while application of sulphur containing fertilizer and organics increased it over control. Organic sulphur was found to be the most dominant fraction (about 96%) followed by heat soluble sulphur. Integration of chemical fertilizers with organics proved better as compared to application of chemical fertilizers alone. Integrated use of inorganic fertilizers in conjunction with organics increased pH, organic carbon, CEC, rice grain and straw yields over inorganically treated plots. Highest grain and straw yield of rice was recorded when 50% N was substituted through FYM. Pre-transplant incorporation of 50% N through FYM produced 76.7 q/ha rice grain yield which was statistically at par with yield obtained under its 25% N substitution.
