Aim: To find out the direct and residual effect of application of organics, inorganics and their combination on yield and yield parameters of rice-maize cropping system. Study Design: The experiment was laid out in randomized block design during kharif season and split plot design during rabi. Place and duration of Study: At Agricultural college farm, Bapatla during 2018-19 and 2019-20. Methodology: After the preliminary layout, paddy was sown in kharif and maize was sown in rabi season. Vermicompost and green leaf manure were applied two weeks before sowing of paddy. Treatments applied for paddy were considered as main plots and each main plot was divided into two sub plots during rabi. Results: Higher grain yield, straw yield, drymatter production at tillering stage were recorded with the application of 50% RDN through vermicompost +50% RDN through inorganics (T9) during both the years of study. However, in succeeding maize, the kernel yield, straw yield and yield attributing characters (drymatter, cob length and test weight) were significantly highest in the treatment which received 75% RDN through green leaf manure+ 25% RDN through inorganic (T5). Among the fertilizer levels applied to maize, S2 (100% RDF) recorded significantly higher dry matter production over S1 (50% RDF) at all the stages of crop growth and during two years of experimentation. Conclusion: Substitution of 50 % N through vermicompost improved rice yield and yield attributes whereas substitution of 75% N through GLM have shown better residual effect in terms of improvement of yield and yield attributing characters of maize. Among the subplots application of 100% RDF significantly increased the yield when compared to 50% RDF.

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.

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.

A field experiment was carried out to evaluate the influence of ground and unground rice straw application as organic manure on the yield and proximate composition of groundnut seeds, at the University of Ilorin teaching and research farm. The field layout was a split plot Complete Randomized Block Design with four replications. The ground and unground rice straw were in the main plot and different application rates of the rice straw (0; 1,250; 2,500; 3,750 and 5,000 kg /ha) were in the subplots. The results revealed that ground and unground rice straws at 1,250 and 2,500 kg/ha application rates significantly increased (p < 0.05) yield attributes such as pods’ number with a range of 48.33-74.33 pod weight (23.95-42.70), number of seeds (45.67-77.33), seeds’ weight (13.55-25.56 g) and hundred seed weight (34.34-38.05 g) as well as some aspect of proximate composition such as ash content, crude protein and crude fats which ranged between 2.71-2.79%, 31.47-31.56% and 46.61-47.13% respectively, in order of their mention. The forgoing study revealed that ground and unground rice straw applied at the rate of 1,250 and 2,500 kg/ha can serve as an alternative for soil nutrient amendment in groundnut as it ensured a reasonable yield that is able to meet the nutritional needs of man and livestock.

The Mean

The present study was conducted to investigate the changes in yield attributes and protein content with the application of zinc and biofertilizers in hybrid rice and chickpea. The experiment was conducted in as a Randomized Block Design (RBD) in Students Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh, India, during 2018-2019 and 2019-2020. The experiment included twelve treatment groups replicated three times in Randomized Block Design. The results revealed that the treatment which received T7 (100 per cent RDN + 25 per cent N FYM + S40 + ZnO + *Azotobacter or **Rhizobium) recorded highest value of all yield attributes and protein content. The mean values of both years of plant height, number of tillers/hill, panicle length, no. of filled grains/panicle, no. of unfilled grains/panicle and total no. of grains/panicle increased up to 96.08 cm, 8.38, 24.29, 181.03, 18.71 and 199.74, respectively in treatment T7 in hybrid rice. Similarly, in case of chickpea the mean values of plant height, no. of branches/hill, no. of pods/plant, no. of seeds/plant, no. of nodules/plant and dry weight of nodules/plant also increased up to 62.60 cm, 5.22, 62.62, 1.88, 17.63 and 2.08, respectively. The protein content was also found to be maximum in Treatment T7 in rice (7.94 and 8.04%) and in chickpea (23.25 and 23.27%) during the years, respectively. Therefore, combination of micronutrients and biofertilizers, as remunerative and beneficial for growth, improved the yield and ultimately productivity of both hybrid rice and chickpea in areas with deficient available micronutrients in soil.

Relative Change

The present study “Relative changes in Boron fractions in black gram rhizosphere” was contemplated with two objectives: 1) To find out the suitable source, dose and method of boron for black gram and 2) To study the changes in relative boron fractionation under black gram rhizosphere. To achieve the present objectives a field experiment was conducted with Greek gram var. IPU2-43 in factorial randomized block design with three sources, four doses and two methods of application of boron replicated thrice at Bihar Agricultural College Farm of BAU, Sabour during the year 2018-19. Three sources were: S1: Borax, S2: Solubor and S3: Boric acid; Doses: D1: 0.5 kg ha-1, D2: 1.0 kg ha-1, D3: 1.5 kg ha-1, D4: 2.0 kg ha-1and methods: Soil and foliar application. Based on the findings of field experiment it can be concluded that the application of 1.5 kg B ha-1 (D3) registered maximum seed yield of (8.27 q ha-1), straw yield of (10.04 q ha-1), nutrient uptake by grain (12.64 g ha-1) and nutrient uptake by straw (16.95 g ha-1) which was statistically at par with the application of 2.0 kg B ha-1 (D4) and was found to be statistically superior over rest of the doses. Among the sources, the maximum seed yield (7.96 q ha-1), straw yield (9.53 qha-1), nutrient uptake by grain (12.42 gha-1) and nutrient uptake by straw (16.36 gha-1)was found to be highest under the plots receiving 1.5 kg B ha-1 through foliar application of Solubor (S2) and the lowest grain yield (7.88 qha-1), straw yield (9.36 q ha-1),nutrient uptake by grain (11.85 gha-1) and nutrient uptake by straw (15.60 gha-1)was recorded from 0.5 kg B ha-1(D1) which was found statistical inferior over rest of the boron doses. Foliar application resulted in a better yield of straw as compared to soil application.

To study the weed management in drilled paddy an experiment was conducted at Agriculture Research Station, Anand Agricultural University, Derol Dist: panchmahal, Gujarat during kharif seasons of the years 2012-13, 2013-14 ,2014-15 and 2015 -16 . Ten treatments for weed management were studied in randomized block design with four replications. Results that all the growth and yield attributes except plant height and test weight were significantly influenced due to different weed control treatments. The grain and straw yield of drilled paddy were also altered significant due to weed control treatments. In general, T2 (two hand weeding at 20 and 40 DAS) recorded the highest yield among all. It was, however, at par with three other treatments which included pre and post emergence application of herbicides. Since, the application of Oxadiargyl @ 90 g/ha f/b Bisbyribac sodium @ 25 g/ha at 20 DAS is one among the dual application of herbicide, it can be recommended for drilled paddy in options of two hand weeding.
