A field experiment was carried out during kharif, 2012 to summer, 2013 under rainfed condition in the organic block of Assam Agricultural University, Jorhat to find out the effect of different green manuring practices and other organic sources of nutrient on productivity of scented (joha) rice and their residual effect on linseed crop. Results revealed that though green manuring practice had no significant effect on yield and yield attributes of both scented (joha) rice and succeeding relayed linseed crop but higher values were recorded with the incorporation of dhaincha as in-situ green manuring in respect of all the yield attributes and yield of both the main and succeeding crops. Among various organic sources of nutrient, application of enriched compost produced the highest yield in both scented rice as well as linseed crop. The increase in grain yield of scented rice with enriched compost over the other sources of organic nutrient and control treatment ranged from 7.33 to 30.04 per cent. The corresponding increase in case of linseed crop ranged from 29.1 to 39.8 per cent which reflected better residual effects of both the sources of nutrient on linseed crop. The residual available nutrient contents in soil after harvest of linseed crop showed similar trends and increased all the major nutrients over their initial status.

Green Manuring

Rice-wheat is the most widely used cropping pattern in Nepal. This cereal-based cropping system is highly nutrient exhaustive and unsustainable from a soil management perspective. They contribute neither nitrogen nor biomass to the soil. The net effect is the export of nutrients from the soil. The unused period between wheat harvest and rice transplanting is the summer fallow, and the incorporation of green manure during this short period increases the yield of both crops and improves the soils chemical properties. Altogether, there were 9 treatments and 3 replications with the randomized complete block design (RCBD). Dhaincha, sun hemp, black gram, cowpea, mung bean, and rice bean were used as pre-rice green manure. No chemical fertilizers were used for the green manure, and in wheat, 150 : 50 : 50 NPK kg/ha was applied. Goat manure was applied at the rate of 10 t/ha. The main objective of the study is to ascertain the residual effect of pre-rice green manuring on the chemical properties of the soil and the yield attributes of the succeeding wheat crops. The chemical properties of the soil were analyzed before and after the harvesting of wheat, and the yield attributes parameters were analyzed. The result showed that the green manure-treated plots gave a significantly higher yield as compared to solely chemical fertilizers-treated plots. The maximum grain yield was obtained from black gram (5.870 t/ha). There was a 39.76% increase in the grain yield in the black gram-incorporated plots as compared to the only-chemical fertilizers-treated plots. There was a highly (<0.001) significant difference in the soil organic matter of the green manure-treated plots and the only-chemical fertilizers-treated plots. The sun hemp-incorporated plot increased the soil organic matter by 71% when compared to the only-chemical fertilizers-treated plot. There was no significant residual effect of pre-rice green manuring on the soil pH in a one-cropping season. However, there was a significantly higher residual effect of the green manure on the soil’s total nitrogen content in all green manure-treated plots. It was found to be the highest (0.087%) in pre-rice dhaincha. The overall results indicate that the incorporation of pre-rice green manuring improved the soil’s chemical properties and increased the grain yield of the succeeding wheat crops in a rice-wheat cropping system.

Weed Infestation

Background: Maize followed by summer pulses is the emerging cropping system in many places in India. Herbicides are the efficient tools for checking weed infestation and their usage is increasing throughout the globe due to increased labour cost and quick weed control. Some herbicides do not degrade quickly and may remain in the soil for weeks, months or years after application and may inhibit the growth of succeeding crops. Methods: Field experiment was conducted in a randomized block design (RBD) during rabi and summer seasons of 2017-18 and 2018-19 to know the residual effect of different herbicides applied in maize on succeeding greengram. Result: The present study revealed that lower density and dry weight of total weeds and higher yield attributes and yield was recorded with the practice of adopting two hand weedings at 15 and 30 DAS, which was however, at par with atrazine 1.0 kg ha-1 as PE fb one HW at 30 DAS, atrazine 1.0 kg ha-1 as PE fb topramezone 30 g ha-1 as PoE and atrazine 1.0 kg ha-1 as PE fb tembotrione 120 g ha-1 as PoE, without any significant disparity among them. Herbicides applied in maize did not alter statistically the enzyme activity and microbial count in the soil at harvest of succeeding greeengram.

The experiment was conducted at the Bangladesh Institute of Nuclear Agriculture (BINA) sub-staion, Tajhat, Ranpure, using potato-Boro-T. aman rice cropping pattern with an objective to evaluate the direct and residual effects of sulphur and zinc on the growth, yield and nutrient uptake by the crops. The surface soil was sandy loam texture, pH 6.3, organic matter 1.24%, available sulphur 6.62 ppm and available zinc 0.45 ppm. The experiment comprised of eight treatments for potato S15Zn2 (T2, T4 and T8, S8Zn1 (T5 and T6)and S0Zn0 (T1, T3 and T7), for boro rice S20Zn4 (T3, T5, T6 and T7) and S0Zn0 (T1, T3, T4 and T6). The experiment was laid out in a randomized complete block design with three replications. Average tuber yield of potato (var. cardinal) varied from 28.29 to 32.86 t ha-1 with the highest yield in S15Zn2 treatment (100% recommended dose) and the lowest was in the S0Zn0 treatment (control). In the second crop (Boro rice), growth and yield attributes, grain and straw yields responded significantly to S and Zn applied either in the first crop or in both crops. The average grain yield varied from 3.51 to 5.27 t ha-1 over the treatments. In the third crop (T. aman rice), the grain and straw yields responded significantly to S and Zn applied either in the first and second crop or in the third crops. The grain yield of T. aman rice varied from 2.96 to 4.46 t ha-1 over the treatments. The growth and yield contributing characters were also significantly influenced by the treatment. There was a significant direct and residual effect of the treatments on S and Zn uptake by the crops.DOI: http://dx.doi.org/10.3329/pa.v19i1.16987 Progress. Agric. 19(1): 33 - 38, 2008

ABSTRACT The aim of this study was to evaluate the residual effect of pesticides sprayed on peach orchards on S. zeamais. The study consisted of two experiments, according to the method of pesticide application. For Experiment I, pesticides were directly sprayed on peach trees and in Experiment II, the application of pesticides was performed under laboratory conditions. In both Experiments, the effect of pesticides was assessed in laboratory through the release of ten weevils per peach fruit. The effect of treatments was assessed by variable number of surviving insects. The results for pesticides [a.i. (ml or g.100L)] have shown that application of treatments in the field (Experiment I), malathion (200) presented persistence at 1DAT (Days after treatments spraying) and control higher than 80%, and thiametoxan (30) up to 3 DAT , while for phosmet (200) and fenthion (100), the control percentage was over 70% at 1 DAT . Under laboratory conditions, the application of the same insecticides showed control of 100% at 120 HAT (Hours after treatment application). In this context, the use of insecticides by spraying plants must be considered an alternative method for the control of S. zeamais in peach, being necessary to the development and adoption of new control tools for its management.

Field experiments were conducted for two consecutive years during kharif and rabi season of 2015-16 and 2016-17 at Research area, Department of Agronomy, CCSHAU, Hisar to evaluate the direct and residual effect of planting methods and phosphorus levels on productivity, agro-meteorological indices, thermal and energy efficiencies in mungbean– wheat cropping system. The experiment was laid out in split plot design during kharif and in split -split plot design during Rabi with five replications at same site during both the years. Main plot treatments consisted of planting methods viz. furrow irrigated raised bed (FIRB) and conventional where as sub plot consisted of three levels of phosphorus, viz., 30, 40 and 50 kg P2O5 /ha applied to mungbean in kharif and sub -sub treatments applied to wheat in rabi were 40, 50 and 60 kg P2O5 /ha. Sowing of mungbean and wheat crops on beds i.e. furrow irrigated raised bed was superior over conventional sowing in respect of productivity. In mungbean, application of 50 kg P2O5/ha to mungbean significantly increased grain yield over 30 and 40 kg P2O5/ha, respectively but it did not differ significantly with 40 kg P2O5/ha. The residual effect of phosphorous applied to mungbean was found to be non significant on yield attributes and yield of wheat. However, direct application of phosphorous to wheat had significant effect on yield attributes and yield. The agro meteorological indices values were similar under FIRB and conventional method however, thermal and energy efficiencies were higher under FIRB planting as compared to conventional and increased with increasing levels of phosphorous.

Acid reactions and low available phosphorus in tropical soils limit forage yield. The aim was to evaluate soil chemical characteristics pH, P and Mg, forage nutritive values, critical soil and plant P levels and the residual effect of each source. The experiment was in a greenhouse with a Rhodic Haplustox, loam texture. Experimental design was a 5 x 4 factorial with five replicates which phosphate fertilizers were triple superphosphate, reactive rock phosphates Gafsa and Arad, and fused magnesium phosphate powder and coarse, applied at rates of 30, 60, 90 and 120 mg kg-1 P and a control treatment without P. The effectiveness of rock phosphates increased due to their residual effect. The coarse fused magnesium phosphate resulted in the lowest efficiency. The P critical level in soil and plant were 18 mg kg-1 and 2.4 g kg-1, respectively. The increase of phosphorus rates provided an increase in crude protein content.

SUMMARYA two-year field experiment on a mollisol at Pantnagar showed that organic sources of N gave generally higher rice yields than the equivalent split dressing of prilled urea (PU). In 1985/86, Sesbania green manuring (40 kg N/ha) and PU (40 kg N/ha) and, in 1986/87, Sesbania (40 kg N/ha) + Azolla (40 kg N/ha) gave significantly higher yields than a split application of 80 kg N/ha as PU. Yield increases were attributed to significant variations in panicles/m2, filled spikelets/panicle and nitrogen uptake by the crop. These components, and grain yield, were significantly correlated with wet soil NH+4-N, which was increased by organic manuring. Wheat grown after each rice crop showed significant residual effects of the different sources of N applied to rice.

A field experiment was conducted for two consecutive years (2011-2012 and 2012-2013) on fine texture soils of Agricultural college farm, Bapatla. The experiment was laid out in a randomized block design in kharif season with four treatments. The treatments consisted of M1 (RDF (Recommended dose of fertilizers) - Control), M2 (10t FYM (Farm Yard Manure) ha-1 + RDF), M3 (1.5t vermicompost ha-1 + RDF), M4 (Green manuring + RDF). During the immediate rabi, the experiment was laid out in a split-plot design without disturbing the soil for succeeding maize with the four treatments given to kharif rice as main plot treatments and each of these divided into five sub-plots to receive five levels of fertilizer NPK application viz., N1 - 75% NPK, N2 - 100% NPK, N3 - 125% NPK, N4 - 150% NPK and N5 - 175% NPK for succeeding maize. Data collected on available NPK after harvest of maize crop were significantly increased with the application of 100% NPK in combination with FYM @10t ha-1 to preceding rice crop, irrespective of the NPK levels applied to succeeding maize crop. However, it was on par with that of green manuring together with 100% NPK during both the years of the study.

A field experiment was conducted to evaluate the effect of land management practices and residual effect of nutrient management practices of rice on the performance of subsequent wheat crop in the rice-wheat cropping system in Agriculture and Forestry University (AFU), Rampur, Chitwan, Nepal during June 2018-March 2019. The experiment was executed in a split-plot, included two establishment methods viz. (i) conventional tilled dry direct-seeded rice followed by (fb) zero tillage wheat (CT-DDSR fb ZT) (ii) puddled transplanted rice followed by conventional tillage wheat (Pu-TPR fb CT) as main plot treatments, and four nutrient management practices: (i) 100% recommended dose (100% RDF; 150:45:45 and 80:60:40 kg N, P2O5, and K2O ha-1 respectively for rice and wheat), (ii) Residue retention @ 5 t ha-1 of wheat on rice fb residue of rice on wheat + 75% RDF of each crop (RR +75%RDF), (iii) Nutrient expert (NE) dose (140:56:53; 140:60:45 kg N, P2O5, and K2O ha-1 for rice and wheat respectively), (iv) Brown/green manuring of Sesbania in rice fb rice residue @ 3.5 t ha-1 in wheat +75% RDF of each crop (BM/GM fb R+75% RDF) as subplot treatments with three replications. The variety of wheat ‘Bijay’ was sown @120 kg ha-1 with spacing 20 cm × continuous. The data on phenology, yield, yield attributes, and economics were recorded and analyzed by R studio. The study revealed that none of the yield attributes and yield of wheat were significantly influenced by the establishment methods. Significantly more effective tillers (281.94 m-2) and grains per spike (44.48) and higher straw yield (5.95 t ha-1) were recorded under NE dose. The grain yield of wheat was 21% and 16% more under NE dose and BM/GM fb R+75% RDF respectively compared to 100% RDF. CT-DDSR fb ZT wheat had slightly less net returns (NRs. 4523 ha-1) than Pu-TPR fb CT-wheat. NE dose was the most profitable. Hence, rice establishment methods were indifferent but NE dose was the best nutrient management practice for better production and profitability for the wheat in the rice-wheat system.
