A study was conducted to assess the impact of different organic manures on soil properties and growth parameters in okra-broccoli cropping sequence. Study area lies in between 32°39' N latitude and 74°47' E longitude at an elevation of 332 meters above the mean sea level in the Shivalik foothill plains of North-Western Himalayas. Surface soil sampling from 0-15 cm depth was done randomly from four spots of the field prior to start of the experiment.
The data on various characters studied during the course of investigation were statistically analyzed by using Tukey’s test with an aim to figure out which groups in our sample differ by using Honest Significant Difference. Further, influence of organic manures on soil physical, chemical and biological properties was studied and was found that there was a significant impact of organic manures on soil physical properties viz. WHC, BD and IR.
In nutrient status, organic manures reviewed a positive impact on Available N, P and Fe. However, available K, S, Zn, Cu, Mn, Total N, Exch. Ca and Mg were found to be non-significant in the experiment. All growth parameters of okra and broccoli including okra yield and curd weight showed significant increase except number of leaves in broccoli.

- Evaluation of crop growth and yield performance in vegetable sequences.
- Statistical analysis of nutrient uptake and soil enzymatic activities.
Excerpt from the Book
INTRODUCTION
Continuous and massive application of fertilizers during early seventies helped in improving the soil fertility and also the replenishment of nutrients lost due to abiotic factors or consumed by the plants and ushered an era of green revolution. After 50 years of green revolution, the continuous trend of application of fertilizers in imbalanced way because of some govt. policies like subsidy on urea led to the emergence of problem of soil and water bodies’ pollution by nitrate. As a result, economic efficiency of fertilizers use as well as quality of crop products deteriorated.
History is the witness that organic manure based agro-production systems continues to support the agriculture growth both quantitatively as well as qualitatively. Researchers concluded that Organic Nutrient Management in agriculture as a way tends to be more promising and reliable to take on all the issues pertaining soil, climate and crop productivity sustainably (Larson and Clapp 1984; Doran and Parkin 1994 and Sudha and Chandini 2003). Organic manure has the tendency to improve soil physical properties through increased soil aggregation, decrease in the volume of micropores while increasing macropores, increased saturated hydraulic conductivity and water infiltration rate thereby improving soil water-holding capacity at both field capacity and wilting point.
